Residential Express Heating & Air

David's expertise shone through as he replaced the coil, performed thorough testing, and answered all my questions about my HVAC unit. Having tried multiple HVAC companies in the past, I've found my go-to in RES. Big thanks to Tre and the rest of the team!

Timely and very professional. David took care of the problem with furnace very quickly. Very pleased with the service.

William was excellent! He identified the issue with the HVAC drain line right away. RES is a great company to work with. They are responsive, knowledgeable and reliable.

Efficient, on time, reasonable price

These guys are the best! On time, friendly, great prices. Stop searching and call these guys for real.

Outstanding service! Brice is a highly skilled technician who carefully explained the issues, walked me through his work, and shared recommendations for long-term peace of mind. Santos, Maged, and David also did an excellent job maintaining my HVAC unit and promptly addressed any concerns I raised. The customer service team is fantastic—responsive, helpful, and quick to assist. I highly recommend them!

I have used RES for five plus years now to maintain my HVAC system. The technicians are knowledgeable and very courteous and professional. They know how to explain things to the lay person and also give repair options. I don't hesitate to recommend them to anyone looking for a company that is consistent in quality, and that they can actually trust. 5 stars everytime!

Big thanks to RES’s Sales Manager Tra and the entire team at RES – Residential Express Heating & Air! We had 5 different quotes and after careful research and consideration, we were absolutely right to have RES replace our air system.

On installation day, Rob and David were fantastic — Rob was attentive, bubbly, and very detail-oriented, while David was humble and helpful. Together, they made sure the installation was smooth and professional.

The system is running perfectly, and we truly appreciate the honesty, hard work, and professionalism of this company. Highly recommend RES to anyone in the DMV/NOVA area!
