It can be caused by a few different factors, including a dirty air filter blocking airflow, a tripped circuit breaker to the outdoor unit, or an incorrect thermostat setting (always make sure it’s set to “Cool” and “Auto” instead of “On”). If those basics check out, you may have a more serious issue like a refrigerant leak or a failing compressor, which requires a certified technician to diagnose and repair safely.

Ice on your AC unit is usually caused by restricted airflow or low refrigerant. A clogged air filter or blocked return vents will prevent warm air from passing over the evaporator coil, causing the temperature to drop below freezing. If your filter is clean and it’s still freezing, turn your system off immediately to let it thaw and call us to check for a refrigerant leak.

A gentle humming or the sound of rushing air is completely normal. However, loud or unusual noises are clear signs of a mechanical issue. For example, a loud banging often means a loose or broken part, while squealing can indicate a failing motor or belt. If you hear these, turn the system off to prevent further damage and book a repair right away.

Water pooling around your indoor unit is almost always caused by a clogged condensate drain line. As your air conditioner removes humidity from your home’s air, that moisture needs a place to drain. If algae, dirt, or debris blocks that line, the water backs up and leaks into your home. This should be cleared out quickly to prevent water damage and mold growth.

A professional preventative maintenance visit is incredibly thorough. Our certified technicians will inspect and clean the condenser coils, check your refrigerant levels, lubricate moving parts to reduce friction, test the thermostat calibration, inspect all electrical connections, and ensure the condensate drain is clear. This comprehensive check guarantees your system is safe, efficient, and ready for the summer heat.
