6 Reasons Why Your A/C Is Not Cooling the House

Home / 6 Reasons Why Your A/C Is Not Cooling the House

AC is not cooling the house

Is your A/C unit running but not cooling the house? During the sweltering days of a Florida summer, a frozen treat and a dip in the pool aren’t always enough to keep you cool and comfortable. 

A functioning air conditioner is essential to beating the summer heat, and nothing ruins a nice day like an A/C that is not working. Today, the experts at Bullseye Home Services share seven possible reasons why your A/C isn’t doing its job.

My A/C Is Not Cooling the House—What’s Wrong?

1. Small Air Conditioner

One reason your AC is not cooling your home could be that it is not the right size. An air conditioner that is too small will not be able to properly regulate the temperature throughout your entire home.

To determine the size and type of air conditioner that is best for your house, you need to consider variables like square footage, insulation, climate, and home construction. Our A/C professionals at Bullseye Home Services can guide you through choosing the right sized unit to optimize cooling in your home.

2. Improperly Set Thermostat

If you have the right size A/C, but it is not blowing cool air, don’t panic. Sometimes the problem is an improperly programmed thermostat.

Make sure your thermostat is set to cool and not to fan, especially if it’s recently tripped a breaker from our Florida electrical storms. You should also check that the temperature settings are where you want them.

3. Dirty Air Filter

Your air conditioner’s air filter component catches dirt, dust, and other debris that could affect its operation. If your A/C is on but is not cooling the house, it could be due to blocked airflow from a dirty filter. 

Some units require replacement filters, but with others, you can clean the air filter yourself. If your A/C is still not performing properly after you clean or replace the filter, you may need a home services technician to help you identify the problem.

4. Frozen Evaporator Coil

The evaporator coil is what removes heat energy and humidity from the air in order to circulate cool air back into your house. You can tell if this component has frozen by looking for:

  • Excessive condensate drainage
  • Higher utility bills
  • Frost on the interior or exterior refrigerant tubing

Inadequate cooling is another sign of a frozen evaporator coil, so if your A/C is not cooling the house and you notice these signs, call Bullseye Home Services for repairs.

5. Refrigerant Leak

If your A/C is blowing air but not cooling your home, another likely issue is the refrigerant. The refrigerant is the chemical in your air conditioner that is responsible for the output of cold air, and a refrigerant leak can result in a lack of cool air or a system shutdown.

6. Poorly Maintained Air Conditioner

In the United States, 75% of homes use air conditioners, and yet many people aren’t aware that keeping your air conditioner clean is only part of the battle when it comes to proper appliance care.

A/C units need maintenance regularly, not just when something breaks. Our team recommends getting a professional maintenance inspection in the spring and again in the fall to make sure your A/C performs properly throughout the entire year.
