Signs Your AC System Needs Repair

Just because your AC is running doesn’t mean it’s running efficiently. Air conditioning systems often don’t show glaring signs of malfunction to the untrained eye until the damage becomes serious.

You don’t want to wait until your AC fails completely before calling us for AC repairs. It’s essential to know the red flags to watch for and nip potential issues in the bud. Otherwise, you risk dealing with more expensive and time-consuming repairs or even complete replacement down the road.

If your air conditioner has any of the following issues, call our Thornton AC repair experts as soon as possible:

  • Your home feels unnaturally warm or humid.
  • Your indoor air quality has gone down.
  • The air conditioner won’t turn on.
  • The AC unit cycles on and off more often than before.
  • Your air conditioning system isn’t providing sufficient airflow.
  • Warm air blows out of the vents instead of cold.
  • Cold air comes out of the vents, but it’s not enough to cool your home.
  • Indoor temperatures vary between rooms or in the same room.
  • The central AC unit or the registers are leaking water.
  • You notice a bad smell from the AC unit.
  • The air conditioning system is making rattling, screeching, or thumping noises.
  • Your energy bills have gone up for no apparent reason.

How to Protect Your AC Unit from Damage

The root cause of many air conditioning problems is overheating due to broken, worn-out, or faulty parts. Our 888 Heating team is always on call for AC repair in Thornton, but there are a few tips you can take advantage of throughout the year to keep your unit in tip-top shape and avoid sudden, unexpected breakdowns.

Here are a few steps you can take to prevent or minimize overheating, reduce wear and tear, and extend the service life of your unit:

Dirty or clogged air filters cause your AC to work harder and run longer to maintain a comfortable temperature. Replacing your air conditioner filter each month can prevent overheating and costly repairs in the future.

The condenser coils in the outdoor unit play a crucial role in your air conditioning system: They contain refrigerant, which cools the air that the AC pumps into your home. To do their job, however, these coils need to be clean. Dirty coils can cause the system to run constantly to bring the indoor temperature down. Eventually, the system will overheat and fail.

In addition to preventing overheating, clean condenser coils can improve the overall efficiency of your air conditioning system.


The refrigerant in your AC unit shouldn’t run out if the system was properly installed the first time around. If you are low on refrigerant, chances are you are dealing with a leak.

Low refrigerant levels, somewhat counterintuitively, can cause overheating as well as frosting due to the increased stress on the system.

Call our team immediately if you suspect a refrigerant leak. Attempting to fix the issue on your own will only make the problem worse.

888 Heating & Air Conditioning is an awesome company. I've had them come out to do annual preventive maintenance checks on my ductless heat pump since it was installed. I have recommended them to friends and family.

Excellent and informative service from Garen. He is clearly an expert and spent time explaining the differences and issues with our two heating units. We'll definitely be contacting 888 for our AC unit servicing in the spring!

These guys do great work and care about the results. At first the zoning was not working as well as I expected but the 888 team returned and made adjustments on several occasions. The system now works beautifully and we are very happy with the results.
