Common AC Problems We Repair

Air conditioning issues can develop in different ways and addressing them early can help prevent more costly repairs down the road. 

Some of the most common AC problems we encounter include:

• Weak or warm airflow. If your AC is running but not cooling effectively, it could be due to low refrigerant levels, a clogged air filter, or leaky ductwork. Restricted airflow makes it harder for your system to cool your home, leading to discomfort and higher energy use. Our technicians inspect these common problems and provide the right solutions to restore efficient cooling.
• Frequent cycling or shutting off. When an air conditioner turns on and off more often than usual, it may be struggling with thermostat malfunctions, dirty evaporator coils, or electrical issues. This not only reduces efficiency but also puts extra wear on your system. We inspect and test components to find the cause of short cycling and provide the necessary repairs.
• Unusual noises or odors. Rattling or grinding sounds often point to loose or worn-out components, while musty smells could mean mold growth inside the unit or ductwork. Addressing these issues promptly can help prevent bigger problems. Our team carefully examines motors, belts, and internal parts to pinpoint the source of the noise or odor and resolve the issue.
• Rising energy bills. If your electricity bill is climbing but your cooling habits haven’t changed, your AC might be overworking due to clogged filters, duct leaks, or aging components. A well-maintained system runs more efficiently, keeping costs in check. We assess system performance, clean coils, and recommend repairs or tune-ups to improve efficiency.
• Leaks or moisture around the unit. Water pooling near your AC could be a sign of a clogged condensate drain line or frozen evaporator coils. Excess moisture can lead to water damage or even mold growth in and around your unit. We clear drain lines, inspect coils, and repair any issues causing leaks to prevent further damage.

With Phoenix’s extreme summer heat and monsoon season humidity, AC systems work hard year-round. If your air conditioner is showing signs of trouble, our team is available seven days a week to diagnose the issue and help restore your homes or business comfort.
