Things You Should Know About AC Repair

When an air conditioning unit isn’t cooling a home, it usually means one or more components need repair. These components could be clogged, frozen, or simply worn out.

AC Repair

Before deciding on an ac repair service, homeowners should check for a license and insurance coverage. In addition, look for a company with great customer reviews. Contact AC Repair North Hollywood for professional help.

The thermostat is the brains of your AC unit. It sends a signal to the cooling system when it’s time to turn on. If your thermostat isn’t functioning properly, you may not be able to cool down your home. In some cases, the problem is as simple as replacing a battery. Before rushing to call for a professional, try these five quick and easy steps to resolve your problem.

The first thing to check is the thermostat itself. If the screen is completely dark, it’s a good idea to change the batteries. This is one of the most common causes of a non-responsive thermostat and can be solved with a simple pair of AA batteries.

Another common issue is a tripped circuit breaker. If the breaker responsible for powering the thermostat has been tripped, simply flip it back on. It’s also a good idea to check for debris around the thermostat and in the vents. Furniture, toys, drapes, and other objects can block airflow through vents and cause your ac to malfunction. It’s a good idea to perform routine maintenance on your furnace, heat pump, and ventilation system to prevent problems like this from occurring.

Thermostat problems are often due to programming issues. If the thermostat is programmed for the wrong type of equipment, running a pre-selected schedule, or has bad connections, it can cause the system to run against your home’s needs. An experienced HVAC technician can help you correct these problems quickly and easily.

Check the Condenser

An air conditioner condenser is the outdoor portion of your AC system that contains a fan, coil, various controls and a compressor. This unit collects latent heat from your home or business and moves it outdoors where it is dissipated into the atmosphere. If the condenser stops functioning properly, it can hinder your air conditioner’s overall performance and possibly lead to the system failing entirely.

The technician checks the condition of your outdoor condenser, inspecting the rust level, checking for any leaks and examining the fan and coils to make sure they are clean. He may use a rough paint brush to clear away debris that is easy to dislodge, but will usually prefer to use a garden hose set at a low pressure. This helps avoid damaging the delicate fins that characterize most outdoor condenser units.

If the large fan inside the condenser isn’t working correctly, it can’t properly circulate heat and cool air. A blown relay switch, bent blades or a malfunctioning motor can all contribute to this problem. Depending on the severity of the issue, the technician can either replace the fan motor or install a new relay switch.

Unusually high energy bills during the summer are an indication that the condenser isn’t operating effectively. This is due to a loss of efficiency that requires your system to work harder to disperse the same amount of latent heat.

Check the Evaporator

If ice forms on your evaporator coil it will greatly reduce the ability of the refrigerant to pull heat out of the air. This is a bad thing for your system because it means that the rest of the system will have to work harder to compensate, increasing your energy bills and stressing the system out, leading to early wear and failure.

The first step in checking the evaporator is to turn off the system and allow it to completely thaw. This can take up to 24 hours. It is important to note that you should never re-activate your AC after it has been defrosted because doing so can cause the evaporator coil to freeze again.

After the evaporator has thawed, it’s time to start looking at the possible causes of the problem. Some of these problems can be as simple as a dirty air filter or blocked return air ducts. Other problems can be more complicated, like a frozen evaporator coil or low refrigerant levels. If the problem is more complex, a professional needs to be consulted for further testing and repair.

In order to properly check the evaporator coil, it is important to perform proper bubble testing and make sure that it was thoroughly evacuated during installation. To do this, a special vacuum gauge (not a manometer) should be used to create negative pressure. A video scope may also be necessary to get an accurate picture of the evaporator coil and its connections. Once a positive screen has been accomplished, it is a good idea to apply a sealant such as BIG BLU to any suspect surfaces. The best areas to begin searching for leaks are the suction and discharge lines due to their large surface area. However, it is recommended to spray coat all of the fittings starting with the compressor and suction line, then moving on to the condenser coil U-joints, and finally the liquid line connection at the evaporator section.

Check the Ductwork

The ductwork is one of the most important components in your AC system. If the ductwork is leaking, it will cause hot and cold spots in your home and it will also increase your utility bills. You should check your ductwork regularly for holes, breaks, and disconnected sections. You should also check the airflow through each register. If you have trouble getting air to flow through your ducts, it may be caused by blockages or a faulty HVAC.

Signs that your ductwork is leaking include a stuffy feeling, high energy bills, and dust buildups in the living spaces of your home. When conditioned air escapes through the leaks in your ducts, it can disturb dust accumulations and force them into open areas. This can lead to asthma and other respiratory distress.

A professional can conduct an inspection of your ductwork to identify problems. They can also repair the ducts to make sure that they are properly sealed. However, you can do a basic duct inspection yourself by doing a tour of your house in the evening with your heater or air conditioner running. Close all the interior room doors, and walk around your home, looking for gaps in ducts or bare sections of ducting.

You can purchase a smoke pencil at your local hardware store to use to inspect your ducts for leaks. It will cost around $30 and will give you a good idea of the size of any leaks in your ducts. Once you have found any leaks, you can patch them up with aluminum foil tape or mastic sealant. Make sure you use the mastic sealant on joints and seams, not in the corners of the ducts.

Check the Compressor

The compressor is essentially an electric motor. This means that it can also experience the same problems as an electric motor, including shorts, becoming grounded, or having open windings. To check for these problems, you’ll need a multimeter with a continuity setting. You’ll also need to shut off the power at the compressor disconnect box before you remove any wires or take any measurements.

Using your multimeter, test the connections to the compressor by placing one lead on the C terminal and the other on the S terminal. If you get a reading of infinity (OL) between the S and C terminals, the compressor is most likely stuck in “locked rotor amps” mode. This is a safety feature that protects the compressor from excessive loads and high temperatures by locking up the rotor until it cools down. The compressor will make a loud humming noise as it rotates in this mode, and it may be extremely hot to the touch.

If the rotor is locked up, but the other tests indicate everything is fine, you might need to rewire the compressor. This could be due to a tripped circuit breaker, blown fuse, mismatched indoor and outdoor units, or damaged wiring.

It’s important to note that any 3 phase electrical equipment is typically 460 volts and can cause severe injury or death if you don’t follow proper procedures. Always consult a professional for help with this type of work.

Types of Residential Heating Systems

Have a wide variety of maintenance requirements. Some, like forced air systems, require ductwork throughout the home and need regular cleaning to maintain efficiency.


Regarding behavioral assumptions, the effectiveness of policies to decarbonize heating depends on households’ willingness to replace existing equipment with low-carbon technologies. Our model projects that this will only happen once expected savings exceed upfront costs by a large margin.

Boilers transfer heat from a fuel source (natural gas, propane, oil, or electricity) to water. That water circulates through a network of pipes to radiators or radiant floor systems that provide warmth in your home. Boilers can also be used to make hot water to power steam engines or to generate electricity.

A boiler system typically includes a tank to hold cold water and a cylinder for hot water. It can be installed in a garage, basement, or closet. A circulating pump sends the hot water from the boiler through a loop of pipes running throughout your house, heating each room. The pump can also be paired with a thermostat to control each room’s heating.

When choosing a new boiler, look for an Energy Star label indicating the system is highly efficient. A higher AFUE rating translates to lower energy bills.

It is important to have a professional inspect your boiler before the start of the heating season. This lets you catch any minor problems preventing your system from working properly.

While modern boilers are safe and efficient, keeping your system clean and free of any fire hazards is essential. This means ensuring paper, plastics, flammable liquids, clothing, wood, chemicals, and children are kept away from the boiler or in a separate boiler room.

Furnace Compare has compiled consumer reviews and lists the best residential boilers. You can find them in the resources section of this article. In addition, you can check out the top-rated gas and oil boilers on the market today from brands such as American Standard and Bosch.

Furnaces are a common method for heating homes. They warm the air with natural gas, oil, or electricity. They circulate that warm air throughout the house through ducts in the walls and floors. These systems typically cost less to purchase and install than a heat pump or mini-split system, but they usually run at lower efficiency levels.

The most common furnaces use natural gas piped from the local utility company. Their burners ignite a hot combustion gas that raises the temperature of the surrounding air, which fans send through the ducts. They can also be powered by propane, oil, or a combination of these. They are popular in cold climates, where temperatures often dip below freezing.

Most furnaces are rated for energy efficiency with an AFUE rating. However, that number only tells you how much of the furnace’s fuel is heat for your home. Other factors can have a significant effect on your comfort and utility costs.

A good furnace design is important to long-term efficiency. For example, oversized furnaces cycling on and off can wear down components faster and waste energy by overworking the unit. Similarly, poor insulation can allow cool air to leak into the system, which increases your energy bills.

Residential furnaces should be regularly cleaned to prevent dangerous carbon monoxide (CO) from infiltrating the air supply. This colorless and odorless gas is produced when furnaces combust fuel, such as natural gas, oil, or propane. If untreated, it can cause dizziness, shortness of breath, and nausea that progresses to mental confusion, unconsciousness, and death. Installing a CO detector can help protect your family’s health.

Heat pumps extract energy from the air, water, or ground outside your home and concentrate it inside. These systems save a lot of energy and carbon emissions compared to conventional furnaces, but they are less efficient in cold climates. Some heat pumps use a simple electric heating strip in the indoor fan coil to help deal with extremely cold weather. Others are available as ductless mini-split units (sometimes called “ductless air conditioning”). Neither system requires a central air duct, but they need an electrical outlet and may not be appropriate for older homes with limited electrical service.

CR’s member surveys indicate the median price paid for installing a ducted heat pump is $7,791, though it varies by brand. A ductless mini-split can cost up to $14,500 to install.

In cooling mode, a heat pump operates like an air conditioner, but in heating mode, it reverses the refrigerant flow through an aptly named reversing valve. That allows the outdoor coil to take on the role of an evaporator and the indoor coil to assume the role of a condenser.

The reversing valve also allows the heat pump to operate close to its full capacity for the specific outdoor temperature, reducing on/off cycling and compressor wear and improving efficiency. Many heat pumps, including all ENERGY STAR-qualified models, offer two-speed compressors to improve energy efficiency and comfort.

Unlike furnaces that burn fossil fuels, heat pumps are powered by electricity, which has a lower carbon footprint than most other heating sources, especially from renewable resources such as rooftop solar or a cleaner grid. However, you should be aware that even a highly efficient heat pump still uses some fossil fuel to generate the electricity it needs to operate.

A ductless system, or a ductless heat pump, is an energy-efficient alternative to a furnace or air conditioner. It uses electric cooling by using refrigerant to draw heat out of a room and issue it outdoors. In the winter, a reversing valve allows it to pull heat from outdoor air and distribute it indoors.

Because they don’t rely on ducts, they eliminate the energy losses associated with ducts that can account for as much as 30% of energy consumption. They’re more flexible, too. Their indoor units can be mounted into a drop ceiling, hung from the top or on a wall, and their compressors are located outside, where they’re relatively quiet.

Their small size makes them ideal for homes without ductwork or for rooms that don’t get enough heating or cooling from the main home system, such as garages, sunrooms, basements, additions, attics, and guest rooms. A mini-split system can have up to four indoor air-handling units (for zones or rooms) connected to one outdoor unit. Because each zone has a thermostat, it’s easy to condition occupied areas.

The upfront cost of a ductless system can be high, and they’re often more expensive to install than central systems or window systems with similar capacity. Also, they require routine maintenance, like washing each unit’s air filter monthly to prevent build-up that can shorten its lifespan.

The electricity used for heating a home can come from any source, including renewables. Choosing a renewable source’s a good idea, as this will reduce the house’s carbon footprint and help meet climate goals. The carbon intensity of space and water heating in homes has declined by about one-third since 2000 due to more stringent building energy codes, a shift from fossil fuel boilers to heat pumps, and a switch to natural gas. Despite these improvements, most new homes still combust fossil fuels for heating. This makes it important to move to electric heating as soon as we have renewable-only sources of electricity to avoid locking in high fossil fuel use.

This is especially true when considering adding a new room to the house. Extending the existing heating system into the new addition may not be practical or economical, so an electrical resistance system is an excellent alternative. This can be a centralized forced-air electric furnace or a group of individual heaters such as electric baseboards, wall heaters, or electric radiant heat.

Different residential heating systems’ levelized cost of ownership (LCOH) can vary greatly, depending on the initial energy production used to produce the electricity and the transmission losses associated with delivering it to homes. It’s also worth noting that the LCOH of electricity-based systems will depend on where you live, as varying fuel prices can alter energy costs. For this reason, it’s critical to look at energy data for your region to see how the cost of residential heating changes over time. Energy use data for residential heating is collected by the U.S. Energy Information Administration and is adjusted for cooling-degree days in the summer and heating-degree days in the winter.

How To Decide Between Residential And Commercial HVAC Systems

There are several differences between a residential and commercial HVAC system. Commercial HVAC systems are generally larger, noisier, and require more power than residential units. Residential HVAC units are less complex and are not required to meet energy efficiency guidelines, but they are much cheaper than commercial HVAC units. They also require less power than commercial systems. Here’s how to decide between residential and commercial HVAC units. After reading this article, you’ll be better equipped to make an informed decision.

Commercial HVAC Systems Require More Power


According to All Temp Air Conditioning & Refrigeration commercial HVAC systems consume approximately 51% of a building’s total energy. While this may not seem like a large number, it’s a significant percentage if you’re a facility manager managing several sites. The reason for the high power consumption of commercial HVAC systems is that they run at a constant speed, which causes them to waste energy. To make matters worse, inefficient HVAC systems can be dangerous for the environment, so it’s important to invest in systems that use as little power as possible.

Residential HVAC systems are generally comprised of indoor and outdoor components. In contrast, commercial systems may include a variety of equipment and multiple thermostats to control the temperature in various zones. This increased complexity means that commercial HVAC systems require more power than residential ones. The difference between the two is most evident in the size of the building. Commercial HVAC systems need to operate more hours and cover larger spaces. Commercial HVAC systems are also larger than residential ones, so they require more power.

There are two main types of energy-efficient HVAC systems: fuel cells and solar panels. Fuel cells use chemical processes to generate electricity and heat, which is recovered in cogeneration. While fuel cells have lower energy consumption than solar panels, they need to be large enough to operate continuously in a full load. Besides being smaller, these systems are also universal and can be used in all kinds of buildings. So, which one is right for you? If you’re not sure, try a simplified model to help you decide.

Another difference between residential and commercial HVAC systems is the use of components. Residential HVAC systems are split, with certain components in the indoor portion and another in the outdoor part. This means that there’s little flexibility in their configuration. Commercial HVAC systems, on the other hand, are modular, which means that they can be expanded and reduced as necessary. These units are designed to change with the demands of the business, and they’re also much larger and bulkier than residential systems.

They Are Larger

Commercial HVAC systems have several advantages over residential ones. Not only do they consume less power, but they are also quieter and larger than residential units. They can be installed on a building’s roof, which makes them less noisy for building occupants, and allows technicians to access the unit without disturbing people inside. Commercial HVAC systems also require more space than residential HVAC systems. The difference is most noticeable in the area of installation.

Commercial HVAC systems have to be more powerful than residential ones because they need to regulate the temperature in a larger space. They are also more complicated than residential HVAC systems because they need to control a larger area. In addition, commercial HVAC systems must meet industry standards because they must be bigger than residential units. These differences make it essential for homeowners to work with HVAC contractors who specialize in commercial systems. These professionals are well-equipped to handle any type of job, from installation to maintenance.

Commercial HVAC systems are larger than residential systems and require different maintenance. They typically have add-on compressors and evaporators. Residential HVAC systems may be installed on a building’s exterior or in the yard. While a commercial system will likely be installed on a building’s roof, it is possible to retrofit a residential unit to meet the needs of a larger space. And if you can’t afford a brand new commercial HVAC system, you can always upgrade and install a smaller model.

A commercial HVAC system has more parts and a more complex design. They also require more maintenance than a residential one. A residential HVAC unit requires one drain pan. A commercial HVAC system, on the other hand, requires multiple drain pans. This helps ensure that all condensation is drained, and there is less chance of an overflow. However, commercial HVAC units are more expensive to maintain, and the building owner hires a technician to do so.

They Are Louder

There are several reasons why residential HVAC systems are louder. One is that older systems do not have noise-reducing features. Other factors can make these units noisier: aging components, size, and the type of insulation used in the home. The following are some of the common causes of home HVAC system noise:

Older air units tend to be noisier than newer ones. While a unit that is 60 dB or lower is quiet, it will still produce noise. In addition, 70 dB or louder is considered annoying. Over 80 dB is similar to the sound produced by garbage disposal. It is easy to understand why most homeowners would want a quiet HVAC system, but these units are typically louder than you might expect. HVAC systems have many moving parts and intense vibrations, and noise is the most common source of home HVAC noise.

They Are More Complex

There are several differences between commercial and residential HVAC systems. Commercial HVAC systems are larger and require more space than residential HVAC systems, and the latter are typically standalone. However, unlike residential systems, commercial HVAC equipment is modular, making it easy for building owners to add or remove ductwork as needed. That said, both commercial and residential HVAC systems may need repairs or renovations at some point. The main differences between commercial and residential HVAC systems are size and power.

Commercial and residential HVAC systems are more complex than one another. Commercial systems are typically placed on the roof of the building so that they can provide heat or cold air to a larger space. Commercial HVAC systems are also larger, requiring more space and power, and are more secure, as they are usually placed on the roof. These differences have many advantages. Commercial HVAC systems require more complex ventilation and drainage systems. Commercial HVAC systems may be located in the attic or on the roof, but the former is more compact and less visible.

A commercial HVAC system can be split into several parts to provide conditioned air to different parts of a building. Residential HVAC systems are generally smaller and have just one drain pan. Commercial HVAC systems may require customization parts that prevent conditioned air from entering different zones. Additionally, the drainage component is larger and more complex. It caters to the large amount of condensate produced by commercial HVAC systems. Residential HVAC systems drain to a single pan outside the structure, while commercial HVAC systems have several pans and multiple pipes.

Commercial and residential HVAC systems differ in complexity and cost. Commercial HVAC systems require a more sophisticated drainage system and higher-tech components. Since residential systems are smaller, they require less attention. Residential HVAC units require routine maintenance, while commercial HVAC systems require a lot of attention and expertise. A commercial system can also be much more expensive to maintain. So, it is important to understand which one is right for you. Before making a decision, check your HVAC system to make sure it is functioning properly.

They Are More Customer-Focused

A new study has found that nearly seventy-two percent of customers won’t buy anything until they read online reviews. While a positive review can help a potential customer decide whether to buy from you, a negative one can make them choose another company. By incorporating social media into your marketing strategy, residential HVAC companies can make the process even more efficient for the customers. Listed below are some tips to help you become more customer-focused.

One of the best ways to attract customers is to offer more services than you typically do. Offering bundles of services is a great way to attract more customers. Additionally, increasing sales training is a good idea. Many companies are turning to technological solutions, such as a software, to improve their customer service. Regardless of what type of customer you have, having excellent customer service is the best way to win customers. Here are some tips to help your HVAC business increase customer loyalty and boost revenue.

Make sure to optimize your website for search engines. 97% of people research local companies online before scheduling an appointment with a local company. And 67% of searchers go past the first page of search results. Using keywords related to HVAC is an effective way to increase your website’s ranking and turn website visitors into leads. But not all HVAC websites succeed in ranking high on the first page of Google, and most of them don’t convert website visitors into leads. Use these tips to increase the chances of getting top rankings and converting website visitors into leads and calls.

Residential HVAC companies need to take a more personalized approach when dealing with customers. By providing more personalized attention and offering more services, HVAC businesses can increase their customer lifetime value. Providing special access to information or products can help you move your customers further down the sales funnel. Whether your business is new or has been around for a while, the importance of excellent customer service cannot be understated. So make sure to stay in the customer’s good graces by keeping in touch with customers.
