Our happy customers

See why Northern Virginia homeowners prefer RS Gregory for their HVAC needs.

We have been using RS Gregory for over 20 years. Steve has installed and maintained our heating and air conditioner units in addition to our hot water unit. Steve is very honest and does a great job. They are a top notch company which we will continue to use whenever we need service.

Carlos V.

Steve and his team did an amazing job! They fixed our HVAC, replaced the coil (and fought for us to get the warranty applied), installed a new return grill as well as a new water heater. Very pleasant and on time. Great experience, not your typical “sales man”.

Antoine T.

We have hired Gregory Heating and Air on two emergency occasions - Steve and the office team have fantastic communications and take the guess work out of the HVAC repair puzzle. Highly recommend them in case of emergency or routine maintenance.

Chris G.

Gregory HVAC has always done a great job servicing my heating and air units and correctly has diagnosed and fixed any issues that have come up with my units. I highly recommend Steve and his company!
