AC Repair in Rockville, MD
Summer afternoons in Rockville put every air conditioner to the test, and the ones that are going to fail usually do it then. Our phones are staffed around the clock, so a dead AC at 9 PM doesn't have to wait until morning. 24-7 HVAC of Bethesda serves Rockville, Twinbrook and King Farm. Our phones are answered around the clock, every day of the year.
Rockville housing and systems
Homes in Rockville are mostly 1950s ramblers in Twinbrook, townhouses in King Farm and Fallsgrove, and condos along Rockville Pike. Twinbrook ramblers usually have compact basement or closet systems with older ductwork, while the newer King Farm and Fallsgrove townhouses mostly have heat pumps with attic air handlers. Knowing the housing in Rockville helps our technicians plan each ac repair call before they arrive, including which parts and tools to bring.
Calls we take in Rockville
- Ice forming on the copper line outside
- Attic air handler dripping into the ceiling
- System running nonstop through the evening
- Breaker tripping on startup
- Upstairs rooms several degrees warmer than downstairs
What a visit includes
In older Rockville homes we also look at the attic air handler and its drain safety switch, because that's where a lot of ceiling stains and shutdowns begin.
Frequently asked
Why is only my upstairs hot?
Attic heat, an undersized upstairs system, or a duct or zone damper problem. We check all of them.
Can you come out for AC repair at night?
Yes. We answer 24/7, and evening and weekend AC calls are common in summer.

Yes. Rockville is about 2.9 miles from our North Bethesda base, and we take calls around the clock for the 20850, 20851, 20852 and 20853 ZIP codes.
About cost
