How Do You Know if You Need AC Repair?

There are some telltale signs that your home needs AC repair. Here are signs you should pay attention to.

1. Blowing Warm Air

Your air conditioning system should blow cool air, not warm air. If you notice a lack of cold air, it could be due to blocked airflow, a faulty compressor, broken thermostat, or something else. Have a HVAC professional check your AC system

2. Strange Noises Inside AC Unit

If you hear loud noises outside of the usual hum when the cooling cycle starts up, it could be a sign of trouble. Rattling, buzzing, grinding, squealing, or scraping can be a sign of a loose part or broken belt.

3. Poor Airflow Out of Vents

If you do not feel air blowing out of the vents, it can indicate an issue with the compressor, a problem with the air ducts, or a broken blower motor.

4. Moisture Leaking From AC Unit

If you see water leaking from the air conditioning unit, or see ice forming on the evaporator coil, this might mean there are bigger issues. If you see refrigerant leaking, that is a major problem.

5. AC System Turns On and Off Again

When a heating and cooling system runs for a short amount of time then shuts off again quickly, this is known as short cycling. When your AC unit turns off and on again frequently, it causes your energy bills to increase, and it also causes your home not to cool efficiently.

6. Your AC Smells Bad When it Runs

Unpleasant smells are one of the clearest signs your air conditioning system needs repair. Musty smells can be a sign of mold in your system, which can make your family sick. Burning smells are almost always a sign of electrical problems.

7. Unusual Spike in Energy Bills

It is normal to see larger energy bills when you run the AC in the summer months. What is unusual is when your energy bill is massively larger than normal. This is a sign that something in the air conditioning system is forcing the cooling cycle to use more electricity than normal.

8. Feels Humid Inside When AC is Running

One of the ways air conditioning works is to remove humidity from the air. If the climate in your home is uncomfortable because it is too humid, this can indicate a major malfunction in your AC system.

9. Thermostat Not Working

The thermostat regulates the temperature of your home by measuring the internal temperature and telling the air conditioning to turn on or off, accordingly. When the thermostat is malfunctioning, your AC might short cycle, or not kick on when it normally would. If your AC system is not turning on, the thermostat may be part of the problem.
