Air Conditioning Repair | AC Blowing Warm Air
Complaints about the air conditioning blowing warm air are a common cause of air conditioning repair. There are a number of potential causes when your home’s AC is blowing warm air. The following are some of the common causes:
A home’s air conditioner is comprised of numerous parts that require the proper function to cool the home. If any single part fails, the entire system can malfunction. A common sign of a problem with the system is the AC blowing warm air.
Refrigerant leaks are a common cause for the air conditioner to blow warm air. While a broad range of potential causes exists, some of the most common are wear and tear, and a lack of routine service. The repair of a refrigerant leak requires a certified HVAC technician for repair.
The air conditioner requires power to operate. A breaker, typically in the home’s electrical service panel, protects this power source. Breakers turn off when there a power overload occurs, or when a breaker fails. A power overload can be due to an overload of the circuit, such as when a power surge occurs. When the AC system experiences frequent power loss due to thrown breakers, consult an HVAC technician and an electrician.
Dirty Air Filter
If air filters are not routinely changed, the airflow through the system will be restricted causing premature wear and tear, and will result in a dirty coil, and potential damage to the system. Eventually, it can lead to problems requiring service and/or repair and the AC blowing warm air.
Early fall days are a time a number of homeowners take advantage of the fresh, cooler air outside by opening a window and adjusting the thermostat from cool to off, and set the blower to manual fan. It is a great way to air the house out and lower the temperature early in the morning, as long as you do not forget to reset the thermostat. Furthermore, a temperature set too high will not allow a compressor to run. When your home’s AC is blowing warm air, check the thermostat first.
The compressor is the heart of the air conditioning system, and when it fails the options are to replace it at great expense or replace the entire system with a new air conditioning installation.
Faulty switches, damaged wiring, and other electrical components are potential causes of the AC blowing warm air. Without power going to components, the system can malfunction and blow warm air, or not operate at all.
Dirty coils can lead to the AC blowing warm air. Not changing the air filter routinely will accelerate the process of a dirty coil. By receiving routine annual, or biannual maintenance, your HVAC technician will monitor for dirty coils, and provide a professional cleaning when necessary. This ensures efficient operation, and increases reliability. A dirty coil can also lead to water running onto the floor, causing damage.
In a split system, the indoor component contains the blower, one of the systems two coils and other components. As the coil sweats, the condensation drops into an evaporator pan with a drain leading outside. When the drain clogs, the evaporator pan can overflow, and has the potential to ruin flooring.
