Surprises are of two types, pleasant and irritating. If you switch on your air conditioner system, and hot air comes from the system instead of cool air, the first reaction can be irritation or anger. Your second response will be to contact a professional technician for HVAC repair in Phoenix.

However, you need not contact a professional technician each time your air conditioner troubles you. You can fix some air conditioner problems yourself with some basic knowledge. If we talk about the hot air problem from the system, here are some reasons you should know to avoid it in the future:

Less Refrigerant

If you know the basic components of an air conditioner, you may be familiar with refrigerant liquid. It absorbs indoor heat from your home and cools your indoor air through contraction and expansion. If this liquid is not adequate in the evaporator coils, the condensed air leaving the system and vents will not be cool but hot.

Thermostat Settings

A thermostat fixes the temperature suitable for your home. If your air conditioner’s components are working perfectly, but the thermostat is in the wrong setting, your home will receive only hot air. You should frequently check your thermostat for its settings and batteries.

Dirty Air Filters

Air filters have two roles while working. For one, they ensure high indoor air quality in your home and second, they maintain smooth airflow in your home and air conditioner. Smooth airflow inside the air conditioner ensures no dust settlement on its parts. However, dust will enter the system and settle on the evaporator coils if the air filters are dirty, leading to ice formation and no cool air.

Frozen Evaporator Coils

As we said, evaporator coils carry the refrigerant, and ice formation on these coils leads to no cool air for your home. You should call a technician for AC repair in Scottsdale when your cooling system starts losing its efficiency.

Dirty Condenser Coils

The condenser coils are in the outside system of your air conditioner, and they ensure the removal of indoor heat by transferring refrigerant from the evaporator coils to them. If the condenser coils are dirty, they will not be able to remove the absorbed heat in the refrigerant, and you will get hot air.

Fan Issues

Fans circulate cool air in your home and ensure smooth airflow along with the air filters. If the fans are clogged or need lubrication, they will not be able to work efficiently, leading to poor airflow and inefficient cooling. If you continue ignoring fan problems, it may lead to compressor breakdowns.

Leaks in Ducts

The ducts carry cool air to all parts and rooms of your home. If there are leaks in the ducts or the ducts do not have proper insulation, the cool air in them will either leak into the walls or become hot. In both cases, your air conditioner will have to work harder for cooling.
