It’s difficult to imagine a time when we lived without air conditioning in our homes. As summer approaches, it’s even more important that your AC functions properly so you can stay cool. What kinds of problems prompt service calls?

We give you a rundown on 7 common air conditioner problems that might require repair or parts replacement.

1. Low Refrigerant

Refrigerant is responsible for removing heat and humidity from the interior. It can run low due to leaks in the refrigerant lines. If this happens, you’ll need to have an HVAC technician find the leaks and repair them. If there are multiple leaks, this can take some time.

2. Frozen Evaporator Coils

If there is a disruption in the airflow around the evaporator coils, they can get too cold, causing a build-up of ice on the outside. You’ll notice the unit begins to put out warm or no air.

3. Thermostat Malfunction

If the thermostat malfunctions, it can cause a number of problems. In some cases, the fix is as easy as replacing dead batteries. If the problem is more complicated, you’ll need to call an HVAC technician.

4. Wear and Tear

Over time, the electrical and mechanical parts can wear out, especially if you neglect regular maintenance. If you hear weird sounds coming out of the HVAC system when you turn it on, that’s a sign of mechanical damage.

5. Fan Problems

There are generally two fans in HVAC units. One blows air over the evaporator coil inside the unit. The other blows air over the outdoor condenser.

Either of these can stop working due to a faulty motor, lack of lubrication, or worn belts. Left alone, this can lead to compressor failure, which is a major problem. In some cases, it’s the end of the road for an AC unit.

6. Leaking Ducts

Ductwork runs behind the walls and ceiling, carrying cooled air throughout your house. If holes or breaks develop, the air will end up in the walls. This causes the system to work harder. If your energy bills rise unexpectedly, it might be a sign of leaking ducts.

7. Clogged Drains

The moisture from AC units gets collected into a pan via a drain line, which eventually leads to a drain. If the line or drain becomes clogged or the pan gets full, water will back up into the system. You can also wind up with leaks in the walls and ceilings, which could cause mold to develop.

8. Neglecting Regular Maintenance

Here’s one more reason, and it may be the most common air conditioner problem. An AC unit needs regular maintenance in order to keep it running at peak level. If you neglect maintenance, you could wind up with major problems that equal expensive repairs.
