The Cost of AC Installation

HVAC Lexington is a necessity in most homes. However, installing a new AC unit can be an expensive process. Several factors contribute to the cost of AC installation. These include the size of the home, energy efficiency, brand, and who’s purchasing the unit.

AC installation involves working with electrical components and refrigerant, which can be hazardous if incorrectly handled. Professional installers have the expertise to ensure safety measures are followed, minimizing risks of accidents or injury.


The cost of a new air conditioning system depends on several factors, including the size of your home and the type of unit you choose. The bigger your home, the more expensive it will be to cool. Additionally, you may need to install new ductwork, which will increase the installation costs. In addition to the price of an air conditioner, you will also need to pay for labor and disposal fees.

The square footage of your home determines which air conditioner will be the best fit, but a professional technician will also take into account other factors such as your lifestyle and energy efficiency goals. A professional can help you find the perfect AC unit for your needs without overpaying.

Air conditioners are rated according to their SEER (Seasonal Energy Efficiency Ratio) rating. The higher the SEER, the more energy efficient it is. Typically, units with a SEER rating above 13 will have lower running costs. You should prioritize a high SEER rating, especially if you live in a hotter climate where you use your air conditioner more often.

If you’re planning to replace your old air conditioning unit, you’ll need to consider the size of your home and whether or not you have existing ductwork. If you don’t, you will need to add new ducts, which can cost up to $7,500 for 300 linear feet of ducting.

You should also factor in any additional costs such as electrical work, insulation and mold testing. It’s important to get multiple estimates from qualified contractors and ask lots of questions. Then, you can make an informed decision about which AC system is right for you.

While you can do some DIY AC installations, this is only appropriate for small wall or window units or ductless systems. Larger or permanent window units should always be installed by a licensed professional. This is because installing a central air system requires extensive electrical and ductwork connections. It’s also a dangerous job that involves heavy lifting, accessing crawlspaces, climbing on the roof and pouring concrete. In addition, most areas require a license, permit, and EPA certification for HVAC technicians.

Air conditioning used to be considered a luxury, but now it’s an essential part of every home. Its benefits include improved health, productivity, and energy levels, as well as higher property values. It also helps keep humidity and mold at bay, which can damage wooden floors and furniture.

The best time to install an AC unit is in the spring when temperatures are mild. During this time, it’s easier for HVAC professionals to work on the outside and inside units. Additionally, this is before the busy summer season, when many people schedule AC installation.

In addition, an air conditioner with a high SEER rating can save you money on your utility bills. These models typically cost more upfront, but they will pay for themselves over the long term by using less energy to cool your home. You should choose an air conditioner with a SEER rating of at least 15 to experience maximum savings.

A good AC installer can help you choose the right model for your home. They can also advise you on how to maintain your system to keep it working efficiently. They can also recommend ductwork and electrical upgrades that will help improve your home’s cooling efficiency.

Another benefit of AC installation is that it keeps your house at a comfortable temperature throughout the day. It’s important to have a cool environment because excessive heat can lead to dehydration, headaches, and other problems. It can even cause mental impairments.

Air conditioning can make it easier to sleep comfortably at night. This will help you wake up rested and ready to tackle your daily tasks. It will also prevent your sleep from being disrupted by hot temperatures.

Air conditioners can also protect your valuable electronic devices from overheating. They can lower the temperature of your living room or bedroom, which will prolong the life of your computer, television, and other electronics. However, it’s important to note that a faulty AC can be a fire hazard, so it’s important to have regular maintenance to ensure safety. A reputable technician will be able to spot minor issues and fix them quickly, reducing your risk of a fire.

If your home’s AC unit is starting to show signs of aging or is not providing adequate cooling, it may be time to replace it. Having a new air conditioner can increase your comfort and reduce your energy bills. However, it’s important to understand the process involved in AC installation before deciding to do it yourself or hire a contractor to complete the job.

The first step of installing a new air conditioning system is to determine the type and size of the unit that you need. This will impact the price and efficiency. In addition, you should choose a brand that is reputable and offers warranties on their products. You should also consider the SEER rating, as this will have a direct impact on your energy costs.

Once you have selected a system, the next step is to prepare the area for the installation. This includes removing any obstructions, such as trees and shrubs, that might get in the way of the equipment. It also involves laying the necessary pipes for refrigerant and water connections. You should also make sure that the unit can be easily accessed by the installers. This is especially important if the evaporator coil is located in a restricted space, such as a closet or basement.

The final step of installing an AC is making the electrical connections. This includes connecting wiring between the indoor and outdoor units and installing protective devices, such as circuit breakers. You should also check for leaks in your ductwork, as these can affect the performance of your new system.

When hiring a company to do an AC installation, you should ensure that they are licensed and insured. In addition, they should be able to provide references from past customers. Having a reliable air conditioning company will help you save money and avoid costly repairs in the future.

Most HVAC companies will provide a free estimate on the cost of an AC system and help you navigate the permit process. This will make the process much easier for you, as the professional will handle all of the paperwork for you. Additionally, many HVAC companies offer maintenance plans for new systems, which will help you keep your air conditioner running efficiently over the years.

Regardless of whether you have new or old AC, there are some maintenance requirements that must be met. These include replacing the air filter, cleaning the evaporator coils yearly, and examining the refrigerant levels. You should also inspect the thermostat and make sure that it is connected to the electrical system and that it is set to the proper temperature. If you are not comfortable performing these tasks, you can always hire an experienced HVAC professional to do it for you.

You can save money on your energy bills and prevent costly repairs by doing routine maintenance of your air conditioning unit. It is best to do this in spring, before the hottest part of the year. In addition, the warmer weather makes it easier for contractors to work on both the indoor and outdoor units. They can also do a comprehensive inspection of your cooling infrastructure to identify any potential problems.

To perform the maintenance, first look for dirt, leaves, and other debris around the condenser unit. You should also trim back or clear the area of shrubs and flowers that can restrict the flow of air to the unit. Additionally, you should check that the drain channel is not clogged with debris or mold. You can also use a fin comb to straighten the cage of the air conditioner’s condensing unit, which often bends over time.

A clogged or dirty air filter can cause your AC to run inefficiently, which increases your energy costs. It is recommended to change your air filters every month or two. It is important to note that the higher the MERV rating, the more efficient the air filter will be. However, it will take more energy to pull the air through the filter, so you should balance your air quality concerns with your energy costs.

Leaky ducts account for a significant portion of HVAC-related energy loss. To detect leaks, you can hold a stick of incense near the air register and any duct connections. If the smoke blows around, it is a sign that there is a leak. Small cracks can be sealed using foil tape, while larger ones can be filled with duct mastic.

A thermostat is a very important part of any air conditioning system. It sends signals to the ac unit and other major appliances in your home so they can function properly. If you have a broken thermostat, your house will be uncomfortably hot or cold, and it will use more energy than necessary. This can also cause serious damage to your system and lead to expensive repairs later on down the road. Fortunately, there are several easy ways to check if your thermostat is working properly without calling in an expensive professional.

The easiest thing to check is whether the thermostat is showing the correct temperature on its screen. If it isn’t, the batteries may have died, or there could be a problem with the thermostat itself. This is easily fixed by changing the battery. If the problem persists, it is time to call in a professional.

Another common AC repair is a weak flow of cool air from your vents. This can be caused by a number of different issues, including clogged filters, a malfunctioning fan, or problems with the ductwork. If you have a clogged filter or a fan that isn’t running, the airflow will be limited, and you won’t be getting as much cool air as you need.

When you are experiencing a lack of cool airflow, the first thing to do is check your thermostat. If the airflow is still poor, it’s likely due to other factors, such as low refrigerant levels or a malfunctioning compressor. A professional will be able to diagnose these problems and recommend the proper AC repair.

If the airflow is good but the temperature isn’t being maintained, there is most likely a problem with the ac unit itself. A professional will be able to use diagnostic tools such as pressure testing and bubble test to identify the issue. In some cases, they will need to replace parts or the entire unit. In addition, a professional can help you with maintenance tasks such as cleaning the coils and checking for refrigerant leaks that can be costly to fix if left untreated.

One of the most common causes of AC issues is a dirty filter. If the air flow is restricted by dust, it can cause the unit to overwork and heat up. This is why you should regularly inspect, clean, or replace the filters to ensure your system is operating properly.

To do this, start by shutting off power to your system. This can be done at the thermostat, breaker box, or at the shutoff switch located on or near your indoor unit (which usually looks like a light switch). Once you have turned off power to your system, locate the air filter. It’s likely to be in the return vent, which is the vent that pulls air from your rooms back into the central system. It may have a label on it or be inside a metal panel with hooks or screws to open. A screwdriver with the appropriate head type can help you remove it. When you take out the old filter, look at it for a sign that it is time to change it. If caked on dirt or dust can be seen easily, this is a good indication that it’s time to change the filter.

Once you have removed the old filter, carefully replace it with a new one. Make sure to check the arrows on the filter to ensure it is placed in the correct direction. Also, note the size of the filter to be able to purchase a replacement at your local hardware store.

You should be able to find several different types of filters, including high-efficiency, low-emissions, and allergen-removal options. Depending on your needs and your home environment, you can decide which filter will best meet your requirements. You will want to keep in mind the MERV rating, which is an industry standard that measures efficiency. A higher MERV rating will require your system to work harder, but you’ll get more airflow out of it. For the most efficient and reliable results, you should choose a middle-of-the-road MERV rating. This will provide good quality and good airflow without putting too much stress on your system.

A failing compressor can be the cause of many different problems. Typically, a technician will perform a few simple tests to determine whether or not the compressor is at fault. These tests include visual inspection, a compressor clutch test, and a multimeter test of the compressor terminals.

First, the technician will inspect the compressor for damage and corrosion. If any damage or corrosion is observed, the compressor may need to be replaced. The next step is to examine the wiring on the compressor. This will include checking for signs of fraying or burning insulation, as well as making sure that the wires are properly connected to the plug. Finally, the technician will perform an electrical resistance test of the compressor. This test will use a multimeter to measure the resistance between the common, start and run windings. Ideally, the resistance should be below 30 ohms.

This is one of the most important tests that a ac repair technician will do. The technician will put a red pin on the terminal C and a black pin on the terminal R, while using the multimeter in the continuity setting. If the resistance is significantly higher than 30 ohms, it could indicate that the compressor has open windings. The technician will repeat the test after the compressor has cooled down to ensure that the readings are accurate.

When performing this test, the ac repair technician will also listen to the compressor for unusual noises. Unusual noises like grinding, squealing or rattling may indicate internal mechanical issues with the compressor. The ac repair technician will then consult the compressor manual to determine the best course of action for the compressor.

In addition to a visual inspection and an electrical resistance test, a ac repair technician will also check the oil for moisture and acid. They will also take a sample of the refrigerant to make sure it is in good condition. In addition, they will check the fuses and circuit breakers to make sure they are working properly. If the fuses or circuit breakers keep tripping, there is probably a problem with the compressor.

A properly working air conditioning system depends on a variety of components, including the ductwork that transports temperature-controlled air from the AC to different rooms in your home. Problems with ducts can cause uneven cooling, high energy bills, and dust accumulation around vents. If you notice any of these problems, it’s time to call an ac repair technician for service.

You can often spot signs that your ducts need repair by looking for holes and leaks. An HVAC professional can use special testing equipment to determine the extent of the duct leakage, but you can also perform a simple test at home. Turn on the HVAC system and slowly move a smoke pencil or incense stick along your ductwork. If the smoke moves or disappears, it’s a good indicator that there is a hole somewhere in your ductwork and that air is escaping it.

If you find insects or rodents in your ductwork, that’s another telltale sign that it is time to get it repaired. These pests often enter ducts through holes and cracks. They can contaminate the air with their urine and feces, which can lead to a wide range of health problems. Fortunately, you can usually prevent this problem by replacing old or damaged ducts with new ones that are tightly sealed and insulated.

Other common warning signs that it’s time to get ductwork repaired include uncomfortably cold or warm spots in your home, a musty smell coming from vents, and high utility bills. You can seal minor leaks in your ductwork with metal foil tape, but you should have an HVAC technician examine and repair extensive or damaged sections of your ductwork.

If you are worried about the cost of AC repairs, consider asking your installer if they offer financing. While you may have to pay interest, it’s often much less than the cost of a personal loan from a bank or credit union. You can also try to negotiate a lower rate with the contractor, which may make it easier for you to afford your needed repairs.
