4 Signs Your HVAC Unit Might Be Failing

If you’ve ever been stuck in the middle of a heatwave, you know just how vital a functioning HVAC unit is. A malfunctioning air conditioner could cause many problems in your home, from mold growth to dangerously high heat levels.
The best way to avoid getting stuck with a broken air conditioner is to regularly monitor your unit for issues. If you see any of the following problems, it might be time to check out one of the many Chicago HVAC contractors in your area.
Weak Airflow
If you notice that the air coming from your vents isn’t blowing as hard as it usually would, that could indicate a failing unit. Problems with your ducts, compressor, and any part in between could cause weak airflow.
Warm Air
Warm air blowing into your home when your air conditioner runs could indicate low coolant in your unit. Coolant is not intended to be refilled at any point, which means low coolant is the most common sign of a leak somewhere in your HVAC system.
Increased Noise
If your HVAC unit runs loudly, that could indicate failing mechanical parts. This is common in an aging system, but it shouldn’t be ruled out in a newer system, either. Common sounds of a failing HVAC unit include clicking, rumbling, rattling, or excessive noise when your unit turns on.
An air conditioner works to help keep humidity levels low inside your home. However, if you start to notice the air in your home feels damp, it could indicate that your HVAC unit is failing. You must contact an HVAC repair professional immediately in cases such as this because the humidity in the air can make your home the perfect breeding ground for mold.
A sweltering day outside can turn downright stifling indoors with no proper air conditioning. Knowing when to call your local HVAC professional will help guarantee you can continue to enjoy the summer months from inside a cool home.
