Why Homeowners Call APEX for AC Repair & Maintenance

When your AC quits on a 95° day, you don’t want a sales pitch — you want cold air. APEX’s cooling techs carry the common parts (capacitors, contactors, refrigerant, fan motors) on every truck so most AC repairs are completed in a single visit.
And if you’re smart, you won’t wait for a breakdown. Our Comfort Club members get two tune-ups a year, priority scheduling, and discounted parts — paying for itself in avoided breakdowns.

Fairfield County Trusts APEX

Rated 4.9/5 across Google, Yelp & Angi

“Our water heater died on a Sunday. APEX was at the door in under two hours, had a new unit installed the same afternoon, and the price matched the quote exactly. Zero surprises.”

“Replaced our old central AC with a Mitsubishi ductless system in our 1920s home. Clean install, respectful of the property, and our electric bill dropped 30% the first month.”

Frequently Asked

AC Repair & Maintenance FAQs

My AC is running but not cooling — what's wrong?

Most likely a low refrigerant charge (usually from a leak), a failed capacitor, a frozen evaporator coil, or a tripped safety. We can usually diagnose in under 30 minutes.

Yes — a $189 tune-up regularly catches a $40 capacitor about to fail on the hottest day, keeps efficiency high (saving 10–25% on bills), and maintains manufacturer warranty eligibility.

12–18 years for well-maintained systems; 10–12 for neglected ones. If your system is over 12 years old and needs a major repair (compressor, coil), replacement is usually the smarter call.

Two tune-ups per year (heating + cooling), 15% off any repair, no overtime fees, priority scheduling, and a 2-year parts & labor warranty on any repair work. $189/year per system.
