Maintaining Normalcy and Keeping Records: Tips for HVAC Maintenance

Why Is My Air Conditioner Producing Warm Air?

by Wanda Franklin

An air conditioner will be a lifesaver on a hot summer day as long as the unit is functioning properly. There is a chance that the unit can break down and fill your home with warm air. These are some aspects of your air conditioner to investigate, and how to potentially solve the problem.

Check Your Thermostat's Settings

Start by checking the most obvious problem, that the thermostat has been changed to turn on the heat! This can easily happen if you have multiple people in the house adjusting the thermostat, or kids that don't know what they are doing. If this is a problem, there are smart digital thermostats that allow you to lock the temperature controls with a password.

Check Your Thermostat's Wires

If the thermostat appears to be working fine, inspect the wiring. Shut down the power running to the furnace and condenser just to be safe, then take your thermostat off the wall. Ensure that all wires are properly seated in the connectors. A very basic thermostat that operates a furnace and condenser should have 4 wires.

  • Red – Power
  • White – Heating controls
  • Yellow – Cooling controls
  • Green – Fan controls

You may have an issue where the yellow wire is loose and disconnected. The condenser will not get the signal to turn on, but the fans will still kick on and push the warm air around the house.

Check Your Air Filters

The air filter is designed to trap all of the pollutants in the air before it gets pushed throughout your home. An air filter needs to be replaced regularly to keep your air conditioner running smoothly. Unfortunately, many homeowners ignore the air filter until there is a problem with it.

A clogged air filter can make it very difficult for air to pass through it. It can cause the air to be warm if the filer is especially dirty, or severely diminish the amount of cold air coming through.

Check The Refrigerant Levels

Refrigerant is what helps produce the cold air from your air conditioner. Refrigerant flows through the coils in liquid form, making them very cold as air passes through them. The cold coils chill the air, which is how your home gets cool.

Low refrigerant could cause the coils to not get very cold, producing warm air. Have the refrigerant refilled to see if that does the trick.

If you still cannot figure out why your air conditioner is producing warm air, it may be time for professional help. Contact an air conditioning repair company like Elite Heating, Cooling and Plumbing to come out to your home and inspect the unit for you.

Hi, my name is Melinda, and when I sold my home three years ago, I realized that I should have been keeping maintenance records. Because I couldn't prove that we had maintained our HVAC system, the home was actually harder to sell than it should have been. I don't want anyone else to lose money on a home sale or to experience the stress of not having the right records. Because of that, I have created this blog. It explains everything you need to know about maintaining normalcy with your HVAC system and keeping records of check-ups and repairs. Please, take a seat and enjoy reading this blog.
