7 Reasons Your AC Might Not Be Cooling

Residential air conditioner unitIt’s really disappointing to turn on your air conditioner on a hot day and not feeling any cold air blow out. It’s possible for an air conditioner to appear to be working without producing any cold air. As your house begins to swelter, consider calling Fort Collins AC repair and troubleshoot with these seven possible scenarios.

The Vents Are Blocked.

Cool air can’t get into your house if you close the door. If your vent is closed or covered by furniture or another object, it’s stopping the flow of cool air. Some people think that closing the vents in unused rooms saves energy, but it actually makes your air conditioner work harder by increasing pressure on the duct system. Check your vents to make sure they are open and unobstructed.

The Filter Is Dirty.

A dirty air filter will make it quite difficult for cool air to pass through. It also makes the machine work harder to push cool air through the house, which can slow airflow. Change your air filter every 3 months or more, especially during seasons when your HVAC system is running more frequently.

The Ductwork Is Leaky.

Ductwork is what distributes cool air throughout the house. If there’s a leak somewhere, chances are the cool air is getting blown into the attic or insulation instead of ending up where you want it to go. Ductwork can get old and brittle over time, which can lead to leaks and tears. A regular AC inspection can pinpoint weak areas in the ductwork or existing leaks to fix before too much cool air is lost.

The Thermostat Settings Need to Be Updated.

Fixing your AC could be as simple as updating your thermostat. If your AC is on but isn’t blowing air, check that the thermostat is turned on and doesn’t need new batteries. It should be set to a “cooling” function that is cooler than the outside temperature. If you update the settings and things still aren’t cooling down, you may need a new thermostat.

The Refrigerant Is Low.

Refrigerant is a liquid that keeps your air conditioner running smoothly. When it’s low, it could make it more difficult for the system to create cool air. Refrigerant gets recirculated through the AC system, which means it typically doesn’t need to get replaced. If your refrigerant level is low, it could be a sign of a leak. Don’t just add more refrigerant without having a professional fix the leak because that doesn’t fully solve the problem.

Insulation Is Poor.

Insulation works as a buffer between the hot air outside and the cooler air inside your home. If the insulation is old or in poor condition, it likely isn’t doing much to stop hot air from entering your home, especially in the attic or upper levels. Attic insulation should be along the floor and wall joists, as well as the wood beams that run parallel to the floor to absorb the sun’s rays. Take a look in your attic to see if the insulation needs to be replaced or repaired. When the insulation is working properly, more cool air stays inside the house so that the AC unit doesn’t have to work as hard.

A Condenser Coil Is Broken.

The condenser coils are the part of the AC unit that is responsible for producing cold air. If the condenser coil is stalled because of a blown fuse, it can seem like the AC system is still running, but it won’t actually be producing any cold air. A broken condenser coil is best repaired by a professional HVAC technician.

If your AC system isn’t cooling your house, it could be due to one of these reasons. Check to see what you can do yourself, and then call a professional to give a thorough inspection and fix the problem. Soon you’ll be on your way to cool air in the hot summertime.
