Inside Crystal City homes
Homes in Crystal City are mostly 1970s and 80s high-rise condos and newer apartment towers. A lot of Crystal City condo units still have their original 1970s or 80s heat pumps or fan coils, and replacement parts and sizing for those units need some care. So when you call for heat pump repair & service in Crystal City, we already know what we're likely walking into.
How it works
We test the defrost controls, reversing valve, capacitors and refrigerant charge, and check heating and cooling before we leave.
Straight pricing
Most heat pump repairs are a single part. You get the price first. On a unit past its prime, you get the replacement number too.
Quick answers
Why is emergency heat always on?
The outdoor unit isn't keeping up. That's the most expensive way to heat, so get it checked.
Do you service rooftop and balcony heat pumps?
Yes, along with the closet air handlers they connect to.
Do you cover all of Crystal City?
Yes. National Landing, Pentagon City, Aurora Highlands and everything around Crystal Drive, Jefferson Davis Highway and 23rd Street.
