AC not cooling repair in Dublin: what we fix

The most common reasons an air conditioner stops cooling are low refrigerant from a leak, a failed run capacitor that keeps the compressor or fan from starting, a frozen evaporator coil from restricted airflow, a dirty condenser coil that cannot reject heat, or a tripped float switch in the condensate drain. Each has a different fix, and each is one we handle every day.

Dublin customers on our AC not cooling repair

★★★★★

Replaced our 20-year-old furnace and AC with a heat pump. Clean install, explained everything, and our summer bill dropped noticeably. Great AC not cooling repair experience.

Anthony P., Dublin
★★★★★

Straightforward pricing, no upsell, and the technician clearly knew heat pumps inside and out. Our system is finally heating properly.

Michael B., Dublin
★★★★★

Had them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.

AC Not Cooling in Dublin: frequently asked questions

Why is my AC running but not cooling?

Most often low refrigerant, a frozen coil, a bad capacitor or a dirty condenser coil. A technician can pinpoint which in about 20 minutes.

Can I just add refrigerant myself?

No. Refrigerant is a regulated substance, and low charge means there is a leak that will drain a new charge just as fast. We find and repair the leak first.

How quickly can you come out?

Same-day service is available across Dublin in most cases, and 24/7 emergency dispatch is always on.
