Why is my AC running but not cooling?

This is often caused by a dirty air filter, low refrigerant charge (freon leak), or a failing compressor. We can diagnose the specific issue quickly.

How much does AC repair cost?

Most minor repairs strictly cover parts and labor. We offer flat-rate pricing so you know the exact cost before we start any work.

Should I repair or replace my air conditioner?

If your unit is over 10-15 years old and requires a major repair (like a compressor), replacement is often more cost-effective. We'll give you an honest recommendation based on your system's condition.

Common AC Questions

Why is my AC freezing up?

Ice on the coils usually restricts airflow. This is caused by a dirty filter or low refrigerant levels. Turn the unit off immediately to prevent compressor damage and call us.

How often should I service my AC?

We recommend a tune-up once a year, preferably in the spring before the summer heat hits. This helps prevent unexpected breakdowns.

What is a SEER rating?

SEER stands for Seasonal Energy Efficiency Ratio. Higher SEER numbers mean the unit is more efficient and costs less to operate. New standards require a minimum of SEER2 14.3 in California.
