4 Reasons Your Air Conditioner Is Not Cooling Your Home

Air conditioning is a modern invention that the majority of people who live in hot climates use around the clock during the summer months. So, when you hear your A/C running but your house begins to get warmer and warmer, it is natural to be concerned. There are many reasons why an air conditioner may stop properly cooling a home, such as:

Dirty Air Filters

Air filters are cheap and only take a few minutes to exchange. But it is not uncommon for homeowners to forget about swapping out their old, dirty air filter for a new one. What many people don't realize is that a dirty air filter can impede air flow and cause problems with your HVAC system. If air can't circulate properly, your home won't cool down like it should. At the first signs of air conditioning issues, check out the air filter to see if you need a new one.

Broken Thermostat

When you set your thermostat to a specific temperature, it is normal to expect your A/C to cool according to settings. But when a thermostat is old or faulty, there can be a disconnect between what temperature you desire for your home and how your A/C runs. If you have a thermostat that is quite old, it is in your best interest to upgrade to a programmable thermostat to help regulate temperatures throughout the day and also lower your cooling costs. If replacing an old thermostat does not fix your cooling problem, it is a good idea to have a licensed HVAC technician inspect your air conditioner.

Insufficient Insulation

A lot of people do not realize that the insulation in a home's attic plays a huge role in how well an air conditioning system can cool a home. If you live in an older home with sub-par insulation, you may find that your home's air conditioner runs constantly, but your home never feels as cool as you would like. If you are in this type of situation, consider having the insulation in your attic checked out and evaluated.Making some upgrades to your attic insulation could potentially lower both your heating and cooling costs. 

Outside Unit Not Operating

If you can hear your air conditioner running but warm air is coming through your vents, there is a good chance that the inside air handler is working well, but the outside HVAC unit is not actually running. If you discover that the outside HVAC unit is not running, you will need to contact an HVAC services company, like Metro Air, to have your unit inspected and repaired. In a lot of cases, an outdoor HVAC unit that is not running is due to a bad capacitor, which can be replaced for an affordable rate.
