Why Is My AC Unit Not Cooling Down My Home?

If you are experiencing higher temperatures in your home than set on your thermostat, it can make your stay frustrating and uncomfortable. The problem might be simple or it might mean you need a new AC unit. Why is your AC not cooling the house? There are several reasons why your AC unit could fail in cooling down your house. They include;

1. Dirty evaporator coils
The fins of the evaporator coils usually act as a chilling surface for the air as it flows over it. When the air filter is too dirty and collapsed, the coils act as the filter. Dirt and debris will accumulate on the fins hence reducing air flow and also acts as an insulator. This reduces the efficiency of your unit hence it does not cool the air enough.

2. Undersize system
For your air conditioner to be efficient it should be properly sized so that it can keep your entire house cool. If you added an extra bedroom or family room you need to upgrade and get a larger air conditioning system. You will need to talk to your HVAC contractor who will advise you on a better solution.

3. Damaged ducts
Collapsed ducts and torn ducts can be the root of your inefficient AC unit. Critters can get in the attic or the crawl space and chew holes in the ducts. Even though you will notice the difference if the tears are small if they are large they could cause an air leak hence reducing the air supply in the house. Before jumping into conclusions have an expert inspect the ducts to ensure that they are in good condition.

In the heat of the summer, it can be quite frustrating to experience high temperatures in the house due to an inefficient AC unit. It is wise to have an annual maintenance by an expert to ensure you are comfortable throughout summer.
