The unrelenting Texas heat and humidity is tough on air conditioning systems.
The last thing residents and businesses in and around Cypress need is an AC blowing hot air when the outside temperatures are creeping toward 100.
Here are some of the most common-found issues that cause air conditioning units to start circulating warm air.
Dirty Air Filters
When the intake air filter becomes overly dirty and clogged, it can severely restrict airflow. This causes the system to overheat and lose its ability to effectively remove heat and moisture from indoor air.
Dirty filters also cause evaporator coils to freeze up, which also directly impacts cooling power.
Check your system’s air filter at least every 30 days — especially during summer — and change the filter as needed, but at a minimum, every 90 days.
Disconnect Box Problems
Your unit’s disconnect box is a safety switch located near the outdoor unit. If this switch malfunctions or is accidentally flipped, it can cut power to the outdoor unit, leading to the AC blowing hot air.
Check the disconnect box switch, and if turned off, simply switch it on. Call an HVAC professional for service if the box appears damaged or turns itself off.
Low Refrigerant Levels
The chemical refrigerant inside your air conditioner cools indoor air by removing heat and humidity when it passes through the evaporator coils under pressure. The system depends on a tight seal, and if a leak develops, the unit will be unable to operate effectively.
Refrigerant leaks are always a job for a professional who can check the levels, detect and repair leaks, and refill the refrigerant to the proper level.
Dirty Evaporator and Condenser Coils
Evaporator coils are part of the indoor unit and absorb heat from inside air. Condenser coils are in the outdoor unit and discharge heat from the refrigerant into the outside air. When either of these coils becomes dirty, it insulates the heat from passing freely into and out of the refrigerant.
Obstructions of the condenser coil can significantly damage cooling effectiveness. A professional should examine and clean the coils, as improper cleaning makes them easy to damage.
Malfunctioning Fan Motor
The fan motor in your outdoor unit is essential for forcing the heat out of the refrigerant through the condenser coil. If this motor fails, the heat will remain inside the refrigerant lines, and the air circulated through the ducts will be warm. A professional technician should repair or replace this complex electrical component.
