If your home is not feeling as cool as it should be, then you might have some type of problem with your HVAC unit. There are many things that can cause this, three of which are listed below. You can contact an HVAC repair company to come fix your unit for you so you and your family can be comfortable inside your home.
Low on Freon
Freon is a gas that is needed to cool your home. If the Freon is low, then your unit will not be able to cool your house.
This gas should never become low. If it is, then you have some type of leak. At this point, it is important that you hire a professional to refill the Freon for you. They will only do this after the contractor determines where the leak is coming from and then repairs it. The leak could actually be in the can the Freon is in, or it could be located somewhere else. In most cases, this leak is not difficult to find so your unit should be repaired rather quickly.
Bent Fan Blades
If you go outside and look at your HVAC unit you will see a fan and coils. When the unit turns on, the fans spin to keep the coils cool. If the blades are bent, the fan will not be able to provide enough air for the coils. If you do see bent fan blades, you can purchase a fin comb to straighten the blades. This should fix your problem. If you are not able to straighten the blades, however, contact an HVAC contractor to do this for you.
Another thing that can cause an HVAC unit to cool is frozen evaporator coils. There are many things that can cause the coils to become frozen, the most common reason being bad airflow. This could be due to a dirty air filter or a leak in the duct work. If you have anything sitting on the vent registers inside your home, this can also cause low air flow.
If there was dirt built up on the evaporator coils, this can also cause the coils to freeze up. If the Freon is low, this can also cause the evaporator coils to freeze.
Talk with an HVAC contractor, like those at Universal Refrigeration, about this information. The contractor can also tell you of other issues that can cause an HVAC unit not to cool a home properly.
