What You Need to Know About AC Repair

Air conditioning units are the superheroes of our homes on hot summer days, but even superheroes need a little maintenance. Learn about AC Repair North Hollywood so you can understand the process better and feel confident calling in the professionals.

AC Repair

A clogged or frozen evaporator coil can prevent your AC from cooling your home properly. A professional can use a vacuum or hose to clear the clog and defrost the coil.

The blower motor in your HVAC system moves air through the ducts and into the cabin, which is how your AC circulates cold or hot air. Like other mechanical and electrical parts, the blower motor can be prone to problems that need professional repairs. A few common problems include poor airflow, an inoperable blower motor, a dirty fan or a faulty capacitor.

Poor airflow is typically a sign that the blower motor needs to be replaced. However, it can also be a sign of a larger problem that needs to be addressed in the system. A lack of airflow can be caused by dust and debris accumulation, a defective motor resistor module or connections, a broken fan or a bad relay. If you can’t find a clear cause of the problem, it’s best to contact a professional air conditioning service.

A squealing noise from the blower motor is another common sign that it’s time for a replacement. This noise may occur every time the blower runs or it may happen intermittently. The sound could indicate that the motor is reaching the end of its life or it may need to be replaced because the bearings are worn out.

An inoperable blower motor is one of the most serious symptoms that your air conditioning system is experiencing. It’s usually easy to identify a problem with the blower motor, but it’s important that you contact an expert to help diagnose the issue and repair it.

A reliable HVAC company will inspect the blower motor before submitting a quote for repair or replacement. This allows them to find the right replacement motor for your system and ensures that it will work properly with the other components in the unit. The right replacement motor will ensure that your system will continue to function well for years to come. A good HVAC company will provide a high-quality replacement and offer a warranty on the new blower motor. They will also ensure that the correct size replacement is used so that your HVAC system continues to operate at peak efficiency.

Thermostat

Your thermostat is your direct line of communication with the HVAC system. It sends signals to the system to turn on and off, and to change the temperature as needed. Thermostats can often get clogged with dust and other debris. This can cause problems with the internal triggers. A faulty thermostat can also result in inaccurate temperature readings. This can lead to energy waste and higher utility bills over time.

A few easy fixes for a malfunctioning thermostat can help you save money and avoid costly AC repair. First, make sure your unit is properly installed. The thermostat should be located in a central area of the home, about five feet off the ground and away from any heat sources such as sunlight, other appliances, heater vents or windows. The thermostat should also be clear of any blockades such as furniture or drapes, which may prevent airflow through the return and supply vents.

Another quick fix is to replace the batteries. Most units have standard AA or R6 batteries that can be changed in minutes, and the process is relatively simple. Lastly, dust the thermostat with a soft brush to remove any build-up. This can be especially important if the unit is old and hasn’t been cleaned in a while.

Thermostats that aren’t responsive to changes in the environment can be frustrating on hot or cold days. A professional technician can diagnose the problem and determine whether it requires a new thermostat, a new blower or another more complex AC repair.

Depending on the severity of the issue, the technician will recommend a course of action that fits your needs and budget. A minor AC repair or replacement can help you extend the life of your unit, while a more complicated problem may push you toward a complete system overhaul. The expert technicians at Gee! Heating & Air can provide you with a thorough inspection and assessment of your cooling system. Contact us today to schedule an appointment! We serve homes and businesses in the greater Detroit, Michigan, area. We offer 24-hour emergency AC repair services, and our technicians are licensed and insured.

Contactor

In addition to capacitors, another common AC component prone to wear and tear is the contactor. This is a type of switch that’s responsible for turning your system’s components on and off. If it fails, your system won’t start or run. The contacts in the contactor snap together through magnetic action each time the system starts up, drawing high peak currents that eventually burn them up. This is caused by a combination of excessive inrush currents, unstable control voltages, and too low transition times between the high peak currents. It can also be exacerbated by dirt, dust or moisture ingress into the air gap around the electromagnetic coil.

The good news is that the contactor and start/run capacitor are relatively inexpensive parts, making them a safe bet to replace when they fail. In fact, your AC technician will likely do this during a routine maintenance appointment — provided that they aren’t dealing with a more serious problem like a refrigerant leak.

Besides replacing the parts that are damaged, your AC technician will also recharge your system. Recharging involves adding more refrigerant to your system, which allows it to cool and dehumidify your home as it should. The process is done by hand, and it requires a special gauge that can measure the exact amount of refrigerant needed to fill your unit.

If your AC repair includes addressing a refrigerant leak, the service technician will have to drain your unit’s lines and drip pan before recharging it. They may also have to repair any faulty connections and seals. If your AC repairs involve a refrigerant leak, it’s important to have a qualified specialist do the job to avoid contamination. They’ll also be able to determine whether your system is in need of a complete replacement or a simple repair. With this information, you’ll be able to make the best decision for your home and budget.

Refrigerant

Many homeowners are unsure what role refrigerant plays in their air conditioner’s operation. It is a chemical compound that can transition from liquid to gas and back again. Its ability to absorb and transfer heat has made it the essential ingredient in cooling, refrigeration, and heat pump systems for decades. While the term “refrigerant” is often associated with a specific brand, such as Freon, the generic name for any type of refrigerant will suffice.

During normal operation, refrigerant travels between two sets of coils in your system: an indoor and outdoor coil. The refrigerant absorbs heat and humidity from the indoor air, which is cooled by the blower fan and then sent outside. This process repeats until the desired indoor temperature is reached. A leak in the system, however, will allow refrigerant to escape.

A professional technician can find the source of a leak and repair it. He will also locate and correct any major underlying issues that may be causing refrigerant loss. When refrigerant is lost, the AC’s output shifts from cool air to room temperature. This can lead to serious safety problems if it is allowed to continue for too long, such as skin or eye irritation and dizziness.

In some cases, your technician might recommend adding more refrigerant to your system to compensate for a leak or other issues. Be wary of any technician who says your refrigerant needs to be topped off, as this could mean they are either trying to scam you or don’t know what they are doing.

Your air conditioning contractor will likely replace your old refrigerant with a new, safe and environmentally friendly option. There are several different types of refrigerants available, including R-22, HCFC-22, and Norflurane. The R-22 refrigerant is being phased out because it contains chlorine, which has been shown to damage the ozone layer. The HCFC-22 and Norflurane refrigerants contain no ozone-depleting chemicals and are safer for the environment.

What Is Plumbing and Why Is It Necessary?

Plumbing is a complex network of pipes that bring freshwater in and remove waste water out. It includes everything from toilets and sinks to water heaters and drains. For more information, click the Website to proceed.

Plumbers use a variety of tools and skills to install, repair, and maintain these systems. They often work with fast-changing technologies and must keep up with evolving regulations.

Plumbing involves the installation, repair and maintenance of pipes and fixtures. It also includes the venting and drainage systems in a building. Plumbing work can range from simple tasks, like repairing a leaky faucet, to more complex projects, such as installing new water heaters or septic systems. Regardless of the scope of the project, all plumbing work must comply with local and national building codes.

Generally, residential plumbing systems are comprised of pipes made from copper, steel or plastic. These pipes transport freshwater in the home, as well as waste water and sewage. They can be run through walls, floors and ceilings. The main function of a residential plumbing system is to supply water and remove waste in a safe and efficient manner.

When it comes to plumbing new homes, builders often rely on plumbers to set up the essential lines. This is usually done before the concrete foundation is poured. It also happens during what’s called the rough-in phase, which is after framing but before hanging drywall. During this time, the plumber will connect all of the major lines to what’s called the stack.

The stack is a series of pipes that carry waste to the sewer system or on-site disposal system. It’s important that this pipe is installed correctly to prevent any health and safety issues down the road. For example, if the stack isn’t properly vented, it could lead to backpressure hazards or even back siphonage.

Besides ensuring that the stack is vented properly, plumbers also install all of the plumbing fixtures and appliances in a home. This includes toilets, sinks, bathtubs, showers and more. Plumbers are also trained to handle gas plumbing, which is becoming increasingly common in many buildings. In fact, some plumbers specialize in gas plumbing and can even be certified as master plumbers. This is because it takes a special type of training and certification to deal with highly pressurized and dangerous gas lines. As such, it’s important to only trust your gas plumbing to a qualified professional.

Plumbing fixtures and appliances can break down or wear out over time, requiring repair or replacement. Plumbers have the tools and skills to fix a wide range of problems, such as leaky faucets, toilets, tubs, showers, drains, and water heaters. Before beginning any repair, it’s important to shut off the water supply valve. Also, be sure to use the right tools for the job and don’t over-tighten fasteners, which can cause them to break. It’s also a good idea to read the manufacturer’s instructions for each fixture and appliance. This can help you avoid common mistakes that can lead to costly repairs.

For more serious issues, plumbers can repair or replace sewage systems and water heaters, as well as install or replace drain lines and vents. They can also handle more complicated tasks such as rerouting or modifying existing pipes to improve their function.

Plumbing systems are complex, but they’re also essential to the comfort and safety of your home. Maintaining your plumbing can prevent expensive repairs and keep it functioning efficiently. For routine maintenance, look for leaks and clogs in faucets, showers, toilets, and drains. Check for water heater problems, like corrosion or mineral buildup, and make sure to regularly clean your pipes and fixtures.

A plumbing professional can help with any of these issues. Plumbers use specialized tools and skills to install and repair pipes, fixtures, and appliances. They can also interpret blueprints and building codes to plan and execute plumbing projects. They may work in residential, commercial, or industrial settings.

Plumbers often work with pipes made of different materials, including copper, steel, cast iron, and plastic. Each type of pipe has its advantages and disadvantages. For example, plastic pipes are lightweight and less expensive than metal, but they can corrode over time. Metal pipes are stronger and more durable, but they can be difficult to install and repair. Plumbers must be able to work with a variety of materials and make the best choice for each situation.

Performing regular maintenance can help prevent plumbing emergencies and extend the life of your fixtures and appliances. Start by looking for leaks and clogs, especially in older pipes. If you notice any, have them repaired as soon as possible to avoid further damage and costly repairs.

Other maintenance tasks include installing and repairing water filters, maintaining hot water tanks, and checking for potential water heater problems. You can do some of these tasks yourself, but it’s always a good idea to call in a professional plumber for more serious issues.

A plumber’s job can be dangerous, especially when they work with sewage pipes. Sewage contains harmful microbes that can cause infections if not properly handled. Plumbers should wear protective clothing and gloves when handling sewage to minimize the risk of infection. They should also carefully inspect sewage pipes for any signs of damage or leaks. They should also be aware of the location of any tree roots that could be growing into sewage lines, as these can cause problems when they grow too large.

Even with proper maintenance, plumbing fixtures may wear out over time and need to be replaced. This includes essential anything that delivers or drains water in a home, like faucets, sinks, toilets, showerheads, and tubs. Replacing these fixtures can improve water quality, reduce energy bills, and improve convenience in the home. Keeping an eye out for signs that plumbing fixtures are wearing out, such as a loss of water pressure or flow, a change in color or smell of the water, and high water and/or energy bills, can help homeowners know when it’s time to invest in new ones. Plumbing suppliers can offer helpful advice and guidance when choosing the right products for a specific project. They can also provide information about warranties and other important details that should be considered.

The work environment in the plumbing field can be physically challenging. It requires a high level of physical strength and endurance, as well as the ability to work in awkward positions for extended periods of time. The work can be stressful, especially when it involves emergency situations. Plumbers must be able to listen carefully to customers’ concerns and respond in an effective way. They must also be able to read and interpret blueprints, as well as follow all safety regulations when working with machinery, tools, and chemicals.

Many plumbers choose to pursue further education after earning a high school diploma or equivalent. This can be done through a number of options, including community colleges, technical schools, and trade schools. These programs can provide additional training in specialized areas of plumbing and offer certifications. Courses may include topics like local plumbing codes and regulations, blueprint reading, math and physics, and welding.

Plumbers can also learn on the job from more experienced colleagues. Many experienced plumbers will often mentor younger employees and share their knowledge and expertise. This can help newcomers to the industry gain a foothold and succeed in their careers.

Plumbing work can have a positive impact on people’s lives by providing them with access to clean drinking water and by safely disposing of waste. Without these systems, life would be much more difficult for many people. This is why it is so important for plumbers to keep up with maintenance and repair work.

The first step in creating a job posting for a plumber is to write a clear and concise description of the position and what qualifications are required. It is also important to include a salary range, as this will allow applicants to determine whether the role is a good fit for them.

Local Law 152 – Gas Line Safety

Local Law 152 Plumbers are part of a larger group of regulations designed to maximize gas line safety. Building owners must have their gas piping systems inspected by a Licensed Master Plumber or someone working under their direct supervision every four years.

Local Law 152 Plumbers

A safety regulation passed by the city’s Department of Buildings in 2016 and taking effect in 2020, Local Law 152 requires periodic inspections of buildings’ gas piping systems. During these inspections, certified and licensed professionals check for leaks and other issues that could lead to dangerous incidents like fires or explosions. The inspections also require that building owners submit a report to the DOB to show they comply with the law.

The law explains how frequently buildings must be inspected, who can conduct the inspections, and other details about the requirements. For instance, a person conducting a Local Law 152 inspection must be either a licensed master plumber or work under the supervision of one. Additionally, only certain insurance policies are accepted by the DOB as proof that an inspector is qualified to perform a Local Law 152 inspection.

Buildings that stay current with maintenance will typically have no trouble passing their inspections. Regular service calls from a trusted plumbing and boiler specialist help prevent the need for major repairs that could fail an inspection. These preventive maintenance services also allow the expert to address small problems that can lead to big problems later on – like radiator water hammer or low water pressure in some apartments.

If a building fails its Local Law 152 inspection, it must have the inspection done again within 180 days of the date of the original inspection. Failure to do so can result in a fine of $5,000.

Local Law 152 inspections are essential to keep the city’s gas piping systems safe for everyone. Keeping up with the inspections will prevent dangerous gas leaks that can lead to disaster in a matter of seconds. It will also help ensure that every tenant has access to safe, reliable energy for heating and cooking.

Having an easy way to track your Local Law 152 inspection dates will help you avoid missing them. We’re happy to share that we now have a dedicated Local Law 152 inspection portal on our website so you can get reminders and never miss an inspection again.

The gas line in most buildings consists of metal lines that carry natural gas throughout the structure. These lines can be subject to corrosion over time, which can lead to dangerous leaks. If left unchecked, these leaks can cause a fire or even an explosion. To avoid these hazards, it’s important to keep an eye out for the signs of a possible gas leak. These can include the rotten egg smell, dead patches of grass near your pipes, bubbles in standing water, and even hearing a hissing sound.

If you notice any of these signs, call your Licensed Master Plumber right away. Licensed Plumbers are trained to know how to detect a potential gas leak, so they can catch it before it becomes a problem. Luckily, catching a gas leak early is the best way to prevent damage to your property or injuries to people who live or work in the building.

In addition to detecting dangerous gas leaks, a Licensed Plumber can also conduct a LL152 inspection to ensure your building is up to code. This inspection involves walking the entire exposed gas piping system from point of entry to tenant spaces (excluding restrooms), as well as inspecting for gas leaks and illegal connections. The Licensed Plumber must complete forms GPS1 and GPS2, submit them to the DOB, and report any unsafe or hazardous conditions.

While it may be tempting to skip a gas piping inspection, doing so can result in a $10,000 fine from the City of Most buildings that keep up with routine maintenance and schedule regular service calls from their plumbing and boiler experts will have no trouble passing their LL152 inspection. This is because small problems are fixed before they have a chance to grow into larger ones that would require costly repairs.

For most buildings, the LL152 inspection is due once every four years. However, if you have a major repair or renovation that needs to be done before the inspection date, you can request an extension from the DOB. Be sure to file this request before the deadline.

Ultimately, the responsibility for compliance with Local Law 152 falls on building owners. They must arrange for the required inspections of their exposed gas piping and submit a certificate of inspection to the Department of Buildings.

Buildings that fail to comply with the requirements of Local Law 152 can be subject to penalties, including fines of up to $10,000. Moreover, noncompliance can pose a serious safety risk to the health and wellbeing of building occupants. Aging gas piping can corrode over time, resulting in dangerous gas leaks or fires. Additionally, gas leaks can lead to carbon monoxide poisoning.

A building owner can avoid these consequences by working with a Licensed Master Plumber (LMP) to conduct the required gas piping inspections. An LMP has the necessary training and experience to ensure that all aspects of a gas piping system are inspected for compliance with Local Law 152. Additionally, an LMP can work with a building owner to correct any violations identified during an inspection and complete the required paperwork for submission to the DOB.

Additionally, building owners can help ensure that they will pass their LL152 inspections by scheduling regular maintenance visits with their plumbing and boiler specialists. These visits can catch small issues before they become larger, potentially hazardous problems. Small issues such as radiator water hammer, low shower pressure, and faulty valves can all be fixed before they lead to an inspection violation.

Finally, a building owner can avoid LL152 penalties by keeping detailed records of each inspection and any repairs made. This includes keeping copies of each certificate of inspection on file.

In addition to these measures, a building owner can also request an extension from the DOB for their LL152 gas piping inspections. This extension can be granted up to 180 days after the inspection due date, and it can only be requested once per inspection cycle.

After a series of tragic gas leaks and explosions that killed several people, injured others, and destroyed buildings throughout the city, the Council enacted a set of rules to protect building residents. One of those rules mandates that all buildings must have their gas piping system inspected periodically. These inspections must be conducted by a licensed master plumber or someone under their direct and continuing supervision. Building owners who fail to adhere to these regulations face severe fines.

A qualified local master plumber can help make the process of complying with this law as simple and stress-free as possible. They can assist with identifying problematic piping issues, filing the required paperwork, and bringing the gas system up to code. In addition, they can provide valuable insight on how to avoid future issues and keep the system up to date with the latest changes.

When a Local Law 152 inspection identifies a hazardous condition, the gas utility is forced to shut off gas service until the issue can be fixed by a licensed professional. This is known as a Class A violation and is the most serious type of violation that can be issued. When a class A violation is identified, it is important to work with a skilled master plumber to have the gas service restored and the violation removed as quickly as possible.

The costs associated with completing an LL 152 inspection and bringing the gas system up to code will vary depending on the specifics of each situation. A reputable and qualified master plumber can help determine what the total cost will be, including any necessary repairs, filings, or closeout costs.

While is not affiliated with the Department of Buildings, we can still help you stay in compliance with this regulation by performing your LL 152 inspection and filing the required paperwork on your behalf. Our goal is to take the burden of keeping your building compliant off of your shoulders, so you can focus on what matters most.

We can also file your LL 152 extension request for you if you are unable to meet the deadline for your next inspection. This gives you an additional 180-day period to have your building’s piping inspected by a certified LMP.

What Is Plumbing?

Plumbers Dunwoody is the network of pipes, fixtures, and fittings that bring water into and remove wastewater from buildings. It’s an essential part of construction projects and ensures clean drinking water, facilitates waste disposal and heating, and protects buildings from damaging water-borne diseases like cholera.

Becoming a plumber has several benefits, but it’s not for everyone. Learn more about what to expect from this trade before making the decision.

The water supply line is vital to carrying fresh, clean drinking water into your home. It’s typically a large-diameter pipe connecting to a public water source or a private well. From there, your water travels through several pipes before arriving at your house. The system also includes a main plumbing valve to shut off the water and a meter that tracks your home’s water usage.

Your drinking water plumbing system depends on the correct functioning of all components for its effectiveness. This includes the piping that transports water, the plumbing fixtures that use that water, and the drains that remove wastewater. The sensitivity of this system means that any issues with it will have far-reaching consequences. For this reason, it is important to maintain a plumbing system with regular inspections and services from professional plumbers.

The pipes transporting water throughout a plumbing system are designed to meet specific requirements. For example, some piping is designed to be corrosion-resistant and can handle high pressures. Other piping is designed to be more flexible and can accommodate curves and bends in the water supply system. The type of piping you choose will depend on the location and purpose of your system and your budget.

For the piping that transports potable water, you’ll want to consider its durability and strength. Stainless steel is an excellent choice, as it’s resistant to corrosion and damage from extreme temperatures and human activities. Other options include galvanized steel and polyvinyl chloride (PVC). PVC is popular for plumbing fixture drainage lines, as it’s inexpensive and easy to work with. It can withstand cold and hot temperatures and is less prone to blockages than copper or steel pipes.

The piping that connects the sanitary drainage system to the water supply system must be leak-proof and backflow-resistant. Backflow is the reversal of flow in a plumbing system, which can introduce contaminants into a safe water supply or cause water to back up into lower-level pipes and fixtures. A backflow preventer assembly, backwater valve, or other device should be installed to protect against this.

Drainage systems collect used water and waste from plumbing fixtures and send it away for disposal. Like supply lines, they are mostly angled downward, using gravity to ensure wastewater moves quickly toward sewerage pipes and doesn’t back up into sinks, toilets, or bathtubs. Drainage pipes also have vents to escape toxic gases and chemicals, preventing foul odors from developing inside homes.

If you have ever noticed a strong sewer smell coming from your home, it’s likely because the standing water in your drain traps has evaporated, allowing sewer gasses to enter your living spaces. To refill their drain traps, you can avoid this by regularly running water at all available outlets, especially your toilets.

Aside from preventing sewer gasses from entering your home, the main function of a drainage system is to prevent wastewater from flooding your property. This is achieved by collecting excess rainwater in gutters and directing it to drains at the lowest point of your structure. In addition, a stormwater drainage system can help minimize erosion and protect gardens and other areas with soil from constantly becoming muddy and washing away.

Because drainage systems are primarily underground, they’re usually out of sight and out of mind until something goes wrong. But when problems arise, it’s important to know whether you have a plumbing or drainage issue so you can call the right plumber.

While plumbing covers everything with water supply and distribution, drainage is responsible for collecting, transporting, and treating wastewater. This includes baths, showers, kitchen and laundry sinks, toilets, urinals, and any other appliance in your home that uses water.

As the name suggests, drainage systems utilize gravity to move wastewater away from your home and into sewer pipes. These pipes are then taken to your local sewerage treatment plant or septic tank. To avoid blockages, it’s crucial to dispose of waste properly, including food scraps, oils, and other liquids, rather than pouring them down the drain. If you suspect your drainage system isn’t working, a plumber can use specialized equipment to inspect your pipes and recommend the right solution.

In addition to delivering water, plumbing systems can also provide heating and cooling. This is achieved through a network of pipes that carry steam, hot and cold water, or gas throughout buildings. The pipes can also transport sewage and other wastes to sewer systems or treatment plants.

Plumbing is a trade that requires extensive training and certification. Many plumbers attend a vocational school or community college to earn their credentials, but there are also opportunities to learn on the job with an apprenticeship. Plumbers must be physically fit and comfortable working with tight spaces and heavy equipment. They often work unscheduled shifts and may be on call for emergency repairs.

It is important to differentiate plumbing from process piping. While both systems use pipes, plumbing deals with fluids for end-user applications, while process piping is associated with industrial manufacturing processes. Knowing the difference can help consumers understand what type of plumbing services to seek and avoid. In addition, it is helpful for consumers to see the distinction when requesting quotes or estimates from plumbing companies. This will ensure that the right plumbing service is fairly priced. This can save homeowners money and reduce the risk of overpaying for plumbing services.

Generally, the more efficient your plumbing system is, the less water and energy it consumes. Improving its efficiency can significantly reduce both your energy and water bills and help protect the environment. Leaks, poorly insulated pipes, and appliances that aren’t energy-efficient all contribute to wasted water and energy, but they can be easily addressed through regular inspections and maintenance.

Energy-efficient plumbing systems use less water and electricity for heating, cooling, and general operation. Their insulated pipes minimize heat transfer and loss and have shorter runs to hot water supply points, which also helps conserve energy. These efficiencies are further enhanced by implementing a hot water recirculation system and using energy-efficient appliances that meet specific energy standards.

The choice of pipe material is another important consideration for a plumbing system’s energy efficiency. PEX pipes are popular among eco-conscious consumers due to their insulation properties and corrosion resistance. Also, the design of a plumbing system can impact its energy efficiency, with pressure regulators helping to maintain an optimal water pressure level that preserves both water and electricity.

Proper plumbing installation has a significant influence on the level of energy consumption in residential and commercial buildings. Its effects range from minimizing water waste and optimizing heating processes to reducing air conditioning costs, promoting water conservation, and adopting eco-friendly practices.

Inefficient toilets account for a quarter of indoor water consumption in residential homes, so checking and fixing leaks promptly is important. Water-efficient showerheads, faucets, and appliances, such as washing machines and dishwashers, can be installed to reduce water usage further. Rainwater collection and greywater recycling systems are other ways to reduce water and energy consumption.

Remembering that a plumbing system can become inefficient over time is crucial, and this often happens without noticeable signs or symptoms. Regular inspections conducted by qualified professionals can reveal hidden issues before they escalate and ensure the plumbing system is functioning at its best. In addition to routine maintenance, upgrading outdated and inefficient equipment with high-efficiency new systems is also advisable.
