Learn moreWhy is my AC not cooling?
The most common causes are a dirty air filter restricting airflow, low refrigerant from a leak, a failing capacitor, or a dirty condenser coil outside. A frozen evaporator coil is usually a symptom of one of these, not the root cause — we diagnose the actual issue rather than just clearing the symptom.
How much does AC repair cost?
It depends on what's wrong — a capacitor replacement, a refrigerant leak repair, and a compressor issue are all priced very differently. We diagnose the system first and give you an exact price before any repair work begins.
Why is my AC freezing up?
A frozen evaporator coil is almost always caused by restricted airflow (a dirty filter, blocked vents, or a failing blower motor) or low refrigerant from a leak. Running the system with ice on the coil can damage the compressor, so it's worth turning the AC off and calling us rather than waiting it out.
Can a dirty air filter really stop my AC from cooling?
Yes — a clogged filter restricts airflow across the evaporator coil, which can drop cooling performance significantly and, in worse cases, cause the coil to freeze. It's the simplest thing to check before assuming something more serious is wrong.
How long does a typical AC repair take?
Many common repairs — a capacitor, a contactor, a clogged condensate line — are completed in a single visit. More involved issues, like a coil replacement or a hard-to-find refrigerant leak, may take longer or require a follow-up part order, which we'll explain upfront.
