It’s always the worst possible time that our heating and cooling systems seem to have something happen to them. Before you call someone to look at your system, here is a list of seven commonly misunderstood HVAC issues.
7 of the Most Common HVAC Problems
1. Clogged AC Filters
Not changing your home’s air filters can lead to various issues, including the system freezing up. This is a common problem that many people face.
The first thing you’ll want to do is turn off your AC to let it defrost. Wait for one to three hours, and then turn on the fan for about an hour. Additionally, you should replace your air filter. From there, your unit should return to normal operation.
2. Loud HVAC Noises
Loud noises from your HVAC system can mean many things, and some require only a quick adjustment. These noises can include buzzing, popping, or clanking.
If your HVAC is buzzing, it could be a loose part in your unit, or the motor is close to quitting. You may want to consider calling a technician to your home to determine the issue.
If there is a popping sound, you may want to try turning your unit on and off again. It may also just be your ductwork expanding.
The last sound is clanking noises. If you hear this sound, it may be a problem with your blower assembly. You will want to turn your AC unit off and call a technician to your home.
3. Refrigerant Leaks
Refrigerant leaks are common in many residential HVAC systems. Refrigeration is the process by which your AC absorbs heat from the air, allowing it to exchange warm air for cooler air.
However, due to the chemicals involved and the dangers they pose, this should be handled by an HVAC professional. Please do not try to do this yourself, as it is dangerous and very complex.
4. Dirty Coils
A dirty condenser or evaporator coil can send many homeowners into a tizzy. This will result in hotter air blowing out of your unit. However, it is not a hard fix.
It only requires some elbow grease to fix. You will want to ensure that you do not damage this during cleaning. You may clean them with compressed air, household detergent, or commercial cleaners.
5. Dirty AC Unit
There are many ways an AC unit may become dirty. This is quite common for many people. This may cause your AC unit to run differently than it should.
To clean the AC unit, you need to take it apart. From there, you must clean out the mats and the curd. Clean window AC units regularly to reduce noise and improve indoor air quality.
6. Broken Fan
There are many reasons an AC unit may blow warm air. A big reason why this may be is a broken fan. Dirt and debris may have gotten in there, causing air to blow out. It may also be a faulty motor, lack of lubrication, or worn belts.
To alleviate this problem, check the fan’s condition. If your blade is dirty, use a vacuum or cloth to clean it. If the problem continues, you may need a professional to come out to your home.
7. Thermostat Problems
The last thing you want to check is your thermostat. Ensure that it is on and set correctly. You may also look at the manual to ensure it is working properly. If it is, you may need to reset it or get a replacement.
You may want to try a programmable thermostat, as the older units are more prone to malfunction. Additionally, this may help with your energy bill.
