Common Problems with Air Conditioners
Maintaining your air conditioner in good shape is an important step towards keeping your home cool. However, there are many things that can go wrong with your air conditioner and prevent it from working properly.
Leakage of refrigerant
An air conditioner that has a refrigerant leaking is not only annoying but can also cause damage to your health. Leaking refrigerant can also increase your energy costs and lead to larger problems down the road.
There are several ways to tell if your air conditioner is leaking. Check the ductwork to determine if it is empty or has holes. You can also look for signs of leaks in the airflow and hear abnormal sounds in the unit.
A leaking AC unit can make your home feel much more humid. This happens because refrigerant is able to absorb heat from the air. The heat is then emitted outside. This can make it more difficult for the AC unit cooling the house.
If your AC is less than 10 years old, you may want to consider getting it repaired. Getting a refrigerant leak repaired is not only expensive, but it could also void your unit’s warranty. Contact your local HVAC contractor if you have any questions regarding your air conditioner. They will advise you on how to best solve the problem.
Air conditioners may leak from wear and tear, damage, or any other reason. Call a qualified HVAC professional if you see any signs of leakage such as water puddles on the floor or water on the unit. They can help you determine if it’s time to replace the unit or if you can simply repair the problem.
Refrigerant leaks are usually caused by holes or cracks in the coils. These cracks can be large or small, and can make a loud hissing or gurgling sound. You can also see tiny bubbles form around the leak, or the air in your home becomes warmer.
Drain pan blockage
Keeping your AC drain pan clean will ensure that your air conditioner runs smoothly, and prevent mold and mildew from growing. A blocked drain can not only make your air conditioner unit less efficient, but can also lead to water damage.
There are several things that you can do in order to keep your AC drain clean. The first is to get a good look at the drain pan. It is possible to find a clog or cracks within the drain pan. You can also check for leaks. If you find that there is water leaking from your drain pan, it may be time to replace the pan.
Next is to test the drain. Place a small amount water in the drain. The clog will be gone if the water drains from the drain line easily. You can do this yourself with a hose or a shop vacuum.
The third step is to get rid of the clog. This may require a tool that is more suitable for a DIY job, such as a plumbers snake.
The fourth step is cleaning the drain. You may need to clean the drain with a wire brush, or a bucket of water. You could also use a dry/wet vac. These tools are able to clear the blockage from your drain.
Clogged AC drains are a common problem. It can cause mold and mildew growth, water damages, and higher cooling bills if left unattended. Maintaining your AC drain regularly is the best way of keeping it clean.
An obstruction in the drain of your AC can cause your AC to stop working. Water can also leak into your home, which can lead to serious damage.
Evaporator coils
No matter if you have a new air conditioner or an older model, the evaporator can cause problems. Understanding the evaporator coil can help you diagnose problems and fix them.
Near the blower fan, the evaporator coils are found in the air handler. They work together with the condenser to remove heat from air. If they become dirty, this can cause them to be ineffective. This can result in inefficient heat removal and higher energy prices.
Regular cleaning of the evaporator coil is essential. This will ensure that the air conditioner runs efficiently and helps to reduce operating costs.
When cleaning the coil, you should use a soft brush. To clean the coil, use warm water and detergent. You should also wear protective eyewear and use a shop vac.
When the coil is not clean, the refrigerant can’t absorb heat from the air. This can lead to the evaporator becoming frozen. This can cause your AC unit to stop being able cool your home.
It is possible for the refrigerant in your evaporator coil to leak. This can make your unit work harder, increasing the chance of it sustaining damage. For this reason, it is best to contact an AC repair professional.
If your evaporator coil is damaged, it is crucial to replace it. This will prevent future problems. You could also replace the access panel.
Another common problem is frozen evaporator coils. This can cause the AC unit to work too hard, increase energy costs, and decrease its efficiency. You may hear hissing and bubbling sounds indicating that the refrigerant is leaking from the unit. If this is the case, it is best to replace the entire unit.
Dial-type thermostats
You can troubleshoot any type of thermostat, including older dial-type models or newer programmable models. A bad battery, or a blown fuse could cause your thermostat to not turn on or display any message. You can also clean the thermostat with canned compressed air.
It is also possible to check the wiring connections for your thermostat. Older thermostats can have loose connections. This can lead to the thermostat not working properly or malfunctioning altogether.
Another problem that can occur is corrosion. Corrosion can also cause problems with your thermostat’s wiring. A qualified HVAC technician can diagnose this problem and fix it. An electronic contact cleaner can be used if you don’t have the necessary skills.
Check the thermostat for loose terminal screws. This is especially common on older thermostats. You may need to replace them with new screws.
The thermostat will display a blank screen when it is charging. This can be a minor problem. It is possible that the thermostat is misreading the room’s temperature. To check the temperature, you can use a small thermometer to place next to it. Both thermometers should read the same temperature.
You may have to replace an older dial-type thermostat. The mercury bulb it uses can cause the thermostat to read incorrectly. The thermostat may need to be calibrated again.
If your thermostat doesn’t power up, it may be due to a blown fuse or a faulty circuit breaker. If you can’t find the problem, it’s a good idea to get a professional to look at it.
Failure to comply with manufacturer’s specifications
Even though your air conditioner may be on the fritz now, it’s still worth checking on it every so often. The good news is that the manufacturer is typically more than willing to help you out. It’s best to be prepared for any future problems, such as a blown or leaky condenser.
Taking the time to get your HVAC system checked out can save you a ton of money in the long run. Be prepared with a list to ask before you go. A few brands offer a courtesy option where the manufacturer will perform the service for you. You get a free duct clean and a full tank cooling fluid for the duration of your contract.
