Why Did My AC Stop Blowing Cold Air?

Why Did My AC Stop Blowing Cold Air?

Air conditioning is essential for safety and comfort on a hot day. When the AC stops blowing cold air, the temperature inside your home or commercial building will rise fast, so you’ll want to act fast, too. Several issues can cause an AC unit to stop blowing cold air. You’ll be able to solve some of these problems, but other more complicated issues will require professional repair.

Air Conditioning Issues You Can Fix Yourself

The following issues are fairly simple to check and fix on your own and usually do not require help from a professional.

1. Thermostat

Check your thermostat settings. Make sure it’s set to a temperature below the ambient temperature. Then be sure it’s set to “auto” rather than “on” which often runs only the fan.

2. Dirty Outdoor Unit

Head outside to make sure your AC unit looks clear of debris and has nothing obstructing its compressor.

3. Dirty Air Filter

A dirty air filter can hinder your AC’s ability to put out cold air. Change the filter, if it’s dirty and set yourself up on a regular filter replacement schedule.

4. Supply and Return Vents

Ensure nothing is blocking your home’s air supply and return vents.

Air Conditioning Problems That Require Professional Repair

If it doesn’t seem like one of the above-listed problems is occurring, you might need to call in a professional. These air conditioning problems are more complex and will likely require a professional’s attention.

1. Mechanical Issues

Mechanical problems like a broken condenser fan, compressor,

2. Low Refrigerant Level

If you hear any bubbling or hissing sounds or see any ice built up on a refrigerant line outside, turn your AC unit off and contact a professional because you probably have a leak.

3. Faulty or Damaged Wiring

Take a look at your unit’s wiring. If you see any exposed wires or something that doesn’t look right electrically speaking, don’t try to fix it yourself.

4. Damaged or Leaky Ductwork

An efficiency audit can determine if you’re losing cool air through inefficient ductwork.
