6 Reasons Your AC is Tripping Your Circuit Breaker

6 Reasons Your AC is Tripping Your Circuit Breaker

Most homeowners don’t realize there is a problem with their A/C unit until it stops working. When the homeowners hear the hum of the blower and compressor running, they assume it is working. Your A/C should keep your home at a cool, comfortable temperature during the hot, humid summer months, but sometimes the inside of the unit itself freezes up and this can affect its ability to function properly.

What you need to do when your A/C is not cooling your home

  1. Turn the air conditioning system off.
  2. Check your filter and clean or change the filter (depending on type) if it is dirty or clogged.
  3. Allow all of the ice to melt completely. There may be ice on the outdoor unit as well as the main pipe of the indoor unit and the area around it. It may take five or more hours for the ice to completely thaw, but it is important to leave the system off during the entire thawing process.
  4. With a new, clean filter installed, turn your system on again to see if the problem is fixed.
  5. If your unit is not cooling or airflow is not improved, turn the system off again and contact a professional for help.

What Causes My A/C to Freeze Up?

Airflow Issues

Ice can form on the cooling or evaporator coil. Restricted or poor air flow could cause your A/C unit to freeze. Reduced air flow as a result of a dirty air filter can cause the coils to become blocked by ice.

Freon Leaks

When Freon (or refrigerant) leaks from your A/C unit it can result in ice buildup around the copper tubing. A trained HVAC professional with certification for handling refrigerant can find the refrigerant leak, repair it, and restore your system to good working order.

Outdoor Temperature

Most outdoor A/C units do not function well in temperatures below 60 degrees F. If night-time temperatures are too low, the system will not operate properly and freeze-ups can occur.

How to Prevent Your A/C from Freezing Up

One way to prevent frozen coils is to schedule preventive maintenance. If your equipment has broken or worn parts, they can be identified and replaced. You can avoid many repair issues with this regular service.
