HVAC reviews in Sterling, Virginia

Very nice young man gave us a Diagnostic on our gas heater. Provided us a reasonable price to replace blower motor. Will decide soon on replacement or not.

Extremely quick response, quick diagnosis, fair and transparent cost, and professional explanation of what was done. This is the second time that RES has bailed me out in a pinch. They have earned my loyalty.

We requested an AC diagnostic priced at $89, and the technician arrived on time and thoroughly assessed our AC unit. He patiently answered all of our questions and addressed our concerns. Fair pricing and an honest, reliable company. Highly recommend!

Our technician let us know when he was on the way and arrived well within the promised window. He was careful and thorough as he checked our furnaces and we will be sure to call Residential Express for all our service needs.

This company is absolutely fabulous! All of their techs are honest, prompt, and informative. They don't try to oversell you on anything and properly educate you how you can care for and extend your cooling and heating units.

Great experience.
Especially impressive with the Tech, Robert N’s professional skill and enthusiasm toward to customer(me and my wife).
He explained clearly the issue with our heating system.
I am very satisfied with the service given by Robert N.

I’m very pleased with Residential Express HVAC. Very professional, knowledgable, skillful , informative, friendly, courteous, on time, understanding, and easy to work with. I highly recommend.

Brice and TJ at residential express were fantastic doing my duct cleaning. Zero hick ups, no up charges, zero mess. Very friendly and professional. My second time with residential express heating - will definitely return.

Sent a text over a warranty-covered issue with my HVAC at 11:30pm on a Friday. These guys responded immediately and had a friendly technician on the ground at my home by 8am Saturday morning. It's 10:30am and we are back up and running!

Tight communication, clarity, responsiveness, and great expertise. Thank you RES, you guys are awesome.

First repair/maintenance job needed some adjustments, but the company coordinated sending a second technician out to fix the issue. Rob was our second technician and he was very professional and thorough. Will definitely be calling to request Rob for future routine maintenance and repairs.

They replaced a broken water heater. It was a fantastic experience from the time I reached out to them until they cleaned up after installation. They were very professional, reasonably priced, and did a great job with the project.

Residential Express is an outstanding small business. The entire team is incredibly personable and professional. Mary, who answers the phone, is amazing — she’s helpful, patient, and great to work with. Dave was excellent and Santos was wonderful as well. This company is honest and straightforward, and they don’t try to upsell or take advantage of customers like some HVAC companies do. I highly recommend them!

So far I can say only good words about the Company, as well as the technician, who repaired our system. A summary: overnight our furnace stopped working, so I called this Company and scheduled a visit for 1400-1700 time window. The technician - Robert called me before noon and informed that he could come sooner, which made me happy. During his visit he displayed a good knowledge of the system, quick decision-making, good quality of work (as far as I can tell), and attentions to details (the system was tested several times). Overall, a very pleasant experience. Would recommend this Company to a friend. I also scheduled another job with them.

We had our annual furnace check up. Our service technician was very thorough and cleaned up afterwards. Such a polite and caring individual. We love this company and recommend them fully.

Santo D. Is the best technician. Always courteous, on time and very thorough. We’ve been RES customers for years and have nothing but great things to say, from servicing and maintenance to sales and installation. Top notch!

TOP NOTCH! IMPRESSED. HIGHLY RECOMMENDED.
-Literally, this company was one of the best we have ever dealt with. No wonder they have great reviews.
-The owner of the company, Tra, was uber responsive. We got answers within minutes.
-We got two very detailed estimates and Tra explained everything in great detail.
-Grateful that we got a very good deal.
-The techs Rob, Daniel, Mario & Favin were professional & efficient. They did an excellent job.
Big thank you to Residential! Tra, we are very happy, thank you.

Loved the service by Residential Express --when they found out we were without hot water, they moved other appointments around to get us hot water within 24 hours. William A. and his team were great installers, and walked me through how to flush our new hot water heater. The price was reasonable and on par with others.

RES is my go-to company for HVAC issues. Recently, they also helped me troubleshoot a hot water heater problem and resolved it quickly without upselling. Over the years, I’ve found this company to be honest and reliable. I have several maintenance contracts with them for my rentals. Mary in the office is always responsive, even after hours and weekends. I’ve found that every technician is extremely professional and technically savvy. One recent case stands out because the technician, David, took the time to explain everything to the tenant, going above and beyond the standard service. The technicians are also very communicative and available, either via text or phone calls. I often receive reports that include pictures and sometimes estimates if needed. Don’t hesitate to contact RES; you won’t be disappointed.

Residential Express is excellent in pricing. customer service, and technical competence. I had RE replacing my AC, furnace, and water heater 6 months go and I am very satisfied with the result and service. I highly recommend this company.

We recently received exceptional customer service from a company that matched its outstanding service. We had our dryer vent and air ducts professionally cleaned. After researching various companies, Christie was the first to respond, providing me with competitive pricing and scheduling my service promptly.
On the day of the service, Bryce and his team executed the work with precision. He demonstrated extensive knowledge and promptly addressed all my inquiries, ensuring a seamless and enjoyable experience. I highly recommend this company and its dedicated staff.

We've been clients of RES for about 18 months now, and their service and support have been exceptional throughout -- both in terms of installing a split in one part of our home and in terms of maintaining our current furnace and AC systems.

Today was no different. David came and did a thorough inspection and cleaning. He was friendly, utterly professional and pleasant to work with.
