My AC is running but not cooling — what could be wrong?

The most common causes of an AC running but not cooling in Houston are: low refrigerant (from a leak), a dirty or frozen evaporator coil, a failing capacitor that won't let the compressor run at full capacity, or a clogged condenser coil on the outdoor unit. Our technicians diagnose all of these in a single visit.

Why It Matters

Houston Heat Doesn't Wait.
Neither Do We.

Houston summers regularly push temperatures above 95°F with humidity that makes it feel far worse. When your AC stops working, indoor temperatures can become dangerous within hours — especially for children, seniors, and pets. That's why we offer same-day AC repair with an average response time of 2 hours across Harris County and surrounding areas.

Our NATE-certified technicians arrive in fully stocked service vans carrying parts for the most common AC failures — capacitors, contactors, refrigerant, motors, and more. In most cases, we diagnose and complete the repair in a single visit, so you're not stuck waiting days for a part to arrive.

We service every major brand including Carrier, Trane, Lennox, Goodman, Rheem, York, and Daikin. Whether your system is 3 years old or 15, we have the expertise and parts to get it running. And with our $0 diagnostic fee when you proceed with repair, you'll never pay just to find out what's wrong.

What We Fix

Common AC Problems
We Solve Daily

Refrigerant Leaks

Low refrigerant is one of the top causes of AC failure in Houston. We locate leaks using electronic leak detectors, repair the source, and recharge your system to factory-spec levels. Running low on refrigerant damages your compressor over time — catch it early.

Failed Compressor

The compressor is the heart of your AC — when it fails, nothing cools. We diagnose compressor failures accurately to determine if repair or replacement is the right call, and give you honest options rather than an automatic upsell to a new unit.

Frozen Evaporator Coil

A frozen coil usually points to restricted airflow, low refrigerant, or a dirty filter — and it can completely shut down cooling. We thaw the system safely, identify the root cause, and repair it so it doesn't freeze again the next hot day.

Electrical & Capacitor Failure

Capacitors, contactors, and control boards are the most common electrical failures in Houston's heat — and the most replaceable. Our vans carry these parts in stock so we can swap them on the spot. No waiting, no return visit for most electrical failures.
