Is your AC noisy, smelly, or blowing hot air instead of cold? Then you need professional HVAC repair services.

Of course, we understand if you’re not convinced by that 2-sentence warning. But, for your own sake, don’t stop reading yet. The fact is, these and other common HVAC problems could pose a dangerous health risk for you and your family.

So, in the interest of keeping you and your loved ones safe, we’ve written you this guide. In it, we list some common HVAC problems, what’s causing them, and why it’s important that you get them fixed right away. If you experience any of these problems, don’t hesitate to contact HVAC services near you.

1. Strange Noises

HVAC units are made to be almost unnoticeable during operation. If you’re startled awake every night when the AC turns on, there’s definitely a problem.

However, the change in volume sometimes develops very gradually over a long period of time. It could happen slowly enough that you don’t notice it getting louder and louder with each cycle.

Go ahead and test it now. If it’s noticeably loud, have it serviced immediately.

Your HVAC could have loose parts that are grinding into other parts. Or it could be debris clogging the system or any number of other causes. In any case, call for professional service before the problem gets worse.

2. Strange Smells

Aside from being unpleasant, bad smells from your HVAC could indicate a dangerous problem. You may have mold in your system or burnt-out wire insulation. Both of these can endanger the health of your household.

3. Weak Airflow

The first thing you should do if you have weak airflow coming from your system is to check the air filter. If the filter is full, air can’t pass through it.

If the filter is clean, there could be several other causes. A clogged or leaky air duct or a failing compressor could be to blame. Have a professional check your system to know for sure.

4. The AC Is Blowing Hot Air

If you’re getting hot air from your AC, turn off the system and call for professional HVAC repair right away. Hopefully, it’s a sign of compressor failure. Otherwise, you could have a refrigerant leak.

Refrigerant leaks are poisonous. So we repeat: keep your system off until you can have it repaired.

5. Excess Moisture and/or Humidity

Puddles of moisture around your HVAC may also indicate a refrigerant leak. But it could also be from a blocked drain tube. Still, just in case, call a professional to handle it.

Excess moisture in your indoor air is also not normal. In fact, a properly functioning air conditioner acts as a dehumidifier. So call for repairs if you’re experiencing high levels of indoor humidity.
