How we handle thermostat installation
Because we're HVAC technicians, we can tell whether the problem is the thermostat or the equipment behind it, and fix the right one.
About Reston homes
Homes in Reston are mostly townhouse clusters from the 1960s through 90s, mid-rise condos near Reston Town Center and single-family homes along the lakes. Many Reston townhouses are all-electric with a heat pump outside and an air handler in a utility closet or attic, and a lot of those original systems are now well past 20 years old. Those details shape how we approach thermostat installation in Reston: what equipment we expect to find, where it sits and how the ductwork is likely laid out.
Cost and timing
Thermostat installation is a flat price, plus the thermostat if you don't already have one. If the system needs a C-wire or adapter, we'll tell you before we start.
Questions we hear
Do I need a C-wire?
Most smart thermostats need one for steady power. If you don't have it, we can add it.
Why doesn't my thermostat match the room temperature?
Bad placement near a window or vent, a failing sensor or loose wiring. We check all three.
