The folks were professional helpful and fast. I appreciated their explanations and advice

They are fantastic, Dave never fails to fix it right the first time. Can't recommend this company any stronger. Do not hesitate to call them. read more

I sent a quote inquiry via Yelp and Residential Express Heating & Air responded with a quick, accurate quote. Scheduling was easy and was done directly through the Yelp app. On the day of service, Brice and TJ arrived on time, wore shoe covers inside the house, and walked through the work order. They were done with our duct cleaning in about 2 hours. I requested an additional, same-day service and they were able to accommodate our dryer vent cleaning at the same time. I consider Residential Express's service to be good quality and good value. They were particularly courteous of our pets and reminded us there was a discount coupon available on their website! We currently have an annual HVAC contract with a larger company we are unhappy with. Residential Express Heating & Air offers personalized service and are definitely considering switching our annual HVAC service contract. Thanks again for helping us take care of our home. I highly recommend sending Residential Express a message about your next HVAC project! read more

My A/C stopped working on the hottest day of the year. Residential Express replied quickly to my request and fixed it at a very reasonable cost the next day. So grateful for them! read more

Excellent service! My AC stopped cooling, and they responded promptly. The technician quickly diagnosed the issue, explained the repair, and fixed it the same day. Professional, responsive, and honest from start to finish. I highly recommend them for reliable HVAC service. read more

First Review: First off, our HVAC died a month after purchasing our new house. We knew it was going to go, but to have it happen on the hottest week of year was less than ideal. We decided to check with several companies to get quotes on replacing the entire unit and RES was one of the places we reached out. I find it exceedingly rare to find a professional team that provides both an amazing product line, reasonable pricing, and great customer service. RES went well above and beyond my expectations! From scheduling with Mary and Tra, to having their team come out for an estimate, for the temporary AC units to help us stay cool for the few days between the new unit would be installed (that literally saved my marriage), to having the team promptly here (who were all so fun and kind to work with), to finalizing my bill with Tra. WOW is all I can say. They did such a great job, and I am looking forward to continuing to work with them. If you find yourself in the same situation as we did, I HIGHLY recommend you connect with this team. Thank you again Tra, Mary, and the rest of the RES Team! Second Review: This team is so great. We had to update our boiler and they were so fast to come in and get an estimate and then so flexible about scheduling. And the service is always 1000% great. If anyone is on the fence about contacting RES, please do it! You will be left very happy working with anyone here. Shout out to David and Mary for this one! Third Review: I love this team: from scheduling, to the meeting, to getting the repairs, to the tips and even to payment. Mary was so quick to schedule the appointment, and both times William came over today and earlier this week to help us fix our very old boiler, he was kind and knowledgeable. He spent a amount of time making sure both my husband and I understood what was wrong and the fix. I feel very grateful to have this team to work with. I wish all my daily interactions were like this! Thank again William and Mary! 5+++ service like always! Fourth Review: Goodness, I love this team. They are so prompt, kind, and efficient. I genuinely feel like I am always being taken cared off with white glove service from start to finish, and always at a reasonable, market competitive price. Of very team I have ever worked with, RES is at the highest end. Always excellent experience. read more

They were very professional, efficient and easy to book an appointment. We will definitely use them again in the future!

I don't think I've ever had a company sent me a pre-diagnostic prior to visiting. So far, impressed by the proactiveness dealing with new clients. read more

It was easy to get an estimate, and I got a quick reply, a fair price, and Professional Service

It started off rocky with a goofed up service order. This was quickly addressed by office staff and I didn't have to reschedule. Great communications, duct cleaning crew professional. Job well done. They went the extra yard and replaced torn dryer vent. Highly recommend for vent and duct cleaning. Thank you! read more

It's rare when you find a company that is fair, professional, and does an outstanding job. Starting with Mary, who quoted us several options and went out of her way to give us fair prices. (Much better than three others.). Daniel and Robert were great as the installation technicians. This is our new favorite for HVAC. read more

Professional, Straight forward, Honest and competitive prices. Robert, William, Tra and others all good.

William and his helpers where professional and courteous. He did a great job of installing our new water heater. And the company charged a reasonable price in my opinion. I would hire them again. read more

Maged just completed the job. He was exceptionally professional, went the extra mile to ensure the job was done right. I'd highly recommend Residential Express ans Maged in particular.​ read more

Brice and TJ did a good job for my dryer vent cleaning. They are professional and thorough. My condo is on the 3rd floor which requires high ladder, and they are one of the few that can do it. They arrived on time with the EST they gave me. They were wearing shoe covers inside my home and took them out when they needed to step outside or even just the balcony, which I appreciate a lot! They cleaned from both inside and outside, they discovered and cleaned a bird nest inside the dryer vent! I definitely recommend them to anyone for dryer vent cleaning. I will contact them again in the future. read more

5 stars service, strongly recommended! The technicians are very professional. Thank you!

BLUF: Price seemed fair & had more confidence in this tech & company than a competitor. Water heater inspected. Cost: about 100 snackers. Tech was professional, courteous, and seemed to genuinely care the quality of his work. Making the appointment was good, too. Responsive, helpful & provided the info I needed. Am I confident that she wasn't just working off a script? Not really, but the tech did live up to what the scheduler said. Will I use them again? Very likely. read more

Had Residential Express back out to winterize our two HVAC units. David has been our tech in the past, and he is just super. He gave us an update on the health of both units and even took care of cleaning the condenser unit outside. Knowledgeable and always professional, we will continue to have Residential Express service our HVAC units. read more

They did not detect a wiring deficiency with the size of my hvac system, even after an inspection and then a quote for a new system 6 months later. I like that they don't upsell, but I wonder about technician experience. read more

RES has been superior. There was the initial point of sale and we were extremely happy with the response time for the installation and quality of the systems we purchased. In addition, they were the best value in NOVA. RES was quick, on time, and thorough for our install. It was only later that we realized there was a minor challenge in the thermostat "smart" function from the manufacturer that had nothing to do with RES. The systems were operational, but just not able to connect to our devices remotely. Regardless, RES took the time and effort to continuously work solutions to ensure our systems were operational and working as advertised. This was even though the manufacturer kept pushing back. RES could have done the same, but Tra and his Team worked tirelessly and without issue to correct our challenge on their own time and pocket. I am extremely impressed with RES's customer service well after the installation. Any time we had questions or needed a response, RES was available. read more

Boy, do I have a fun story for Yelp-land! It's a story about us, RES clients, who were fired by the company. How did we get fired, do you ask? Did we not pay our bills? Nope. Were we rude and unprofessional? Nope! We were fired by RES because they couldn't figure out how to fix our humidity issue after servicing our house for YEARS. When we asked them for a solution to our problem and told them that we were unhappy, they told us they didn't have a solution to our problem and to take our business elsewhere. So, I'm posting this review to tell everyone on Yelp-land to take your business elsewhere as well!!! Good riddance, RES. UPDATE- SEE THEIR RESPONSE BELOW. TERRIBLE CUSTOMER SERVICE and rude to boot!!! read more

I highly recommend RES Heating and AC. RES recently installed my AC unit and repaired my furnace. I want to specifically provide recognition for Maged, who overall provided exceptional service. Maged repaired the unit, performance routine maintenance, cleaned the space, and answered all my questions in a way that helped me learn more about my own house. Highly recommend this company and technician!!! read more

timely communication. Professional and polite staff who diagnosed the issues and made recommendations to remedy. charged fair price and also had sun-contract recommendactions for items not serviced by the company. Also, had a shadow program during as well (brought a young man who was interested in becoming a technician). LIves that our technicians help others decide on career choices, which I thought was a very good way to encourage the next generation on a solid trade skill. read more

I needed a company to service my HVAC, clean my vents, and figure out why there was so much lint in my attic. So happy to have found RES - they were so easy to work with, and able to resolve the issues in one visit. They did a fantastic job, and I will be using them going fwd for any maintenance or repairs. read more

CONGRATULATIONS to RES for being smart enough to employ a technician as experienced, knowledgeable and pleasant as technician MAGED! I decided to call RES after thoroughly evaluating competitors, and it wasn't ONLY its 500 5-STAR ratings on YELP(!), but also its lowest price for a maintenance call compared with competing companies that prompted my decision. Technician Maged called in advance of the day scheduled, arrived on-time, wore foot protection (which he had to repeatedly put-on and take-off), and he took the time to explain precisely what was happening with my elderly HVAC system and WHAT he was doing AS he was doing it. MOST IMPORTANTLY--he could have tried to "upsell" me; but to the contrary, he explained to me the history of my units and how my idea of investing MORE money into them at this time wouldn't be advantageous. Maged is an excellent reflection on RES, and experiencing his exceptional, honest service bolstered my confidence in my decision to call RES. Maged identified ways to ensure that the system would last as long as possible. As a result, I'll call RES in the future not only for continued maintenance, but also at the time that I'll need to replace the unit, which it seems will be required in the not-too-distant future. Thank you, RES, for excellent training (and retaining) of technicians such as Maged! read more

Just want to make everyone aware that they do not offer free consultations/quotes like other reliable companies in the region. This year was the 3rd year I asked the company to perform annual HVAC maintenance and cleaning for my unit. Upon arrival, the technician said the work requested cannot be done because the cooling of my AC is not working, but he said he can diagnose and measure my current AC and provide me a quote for replacement. It costs me $119 in the end, same price to the original cleaning and maintenance work I requested and it's not done. I received only a quote that cost me $119...hmmm? If anyone is looking to replace the AC, don't waste your money on this one. I've got three quotes from other companies in the same region, it is possible to get FREE consultation and valuable and reliable quotes. Replying to owner's comments: so there is free quote option, then why I am not offered for this option at all during technician's visit? For a professional technician, isn't it too obvious to you to give truthful professional opinion that my machine is just too old and replacement is the only way that works? During last two year's annual cleaning services, I got honest comments that the machine is going towards end of the life and your technicians mentioned the company can provide me quote, no one mentioned about diagnostics. This year the machine is not working, so cleaning services cannot be done. But your staff is there already so they need to earn the money so the visit is not wasted, therefore only options during the visit to me is to pay for a $119 diagnostics and not provide me free quote services? Well done you tricked me. read more

My AC stopped working and I called RES Heating and AC based on the reviews on Yelp. Technician Mageo arrived on time, quickly identified and fixed the problem. Price was fair. I will definitely call them again. read more

I found Residential Express Services Heating & AC on yelp. I sent a message to inquire about getting our ducts cleaned and the person responded within minutes. They were on time, had great communication, and fairly priced. I'll be using them again in the future for sure. read more

I sent a message to RES Heating & AC on a Friday to see if they could clean out a clogged dryer vent. I received an immediate response letting me know that they could have 2 technicians at my house on Monday. They also provided details of charges for service visits and a preliminary estimate. Brice and TJ arrived promptly at the appointed time and they were kind enough to take a look at our second dryer downstairs as well. Both dryer vents were full of lint and Brice and TJ were able to vacuum out the entire line from the dryers to the exterior of the house (Brice also found a birds nest in one vent). The entire visit took less than an hour and both Brice and TJ were extremely knowledgeable, efficient, and courteous. They took care to wear booties in the house to prevent tracking dirt inside and Brice also washed off the siding which had become a little stained from all the soiled lint. Brice gave me a discount for the two concurrent services, and RES also has coupons available on their website so I got an extra $20 off. There is a separate charge if the technicians have to use a 10, 20, or 30 foot ladder to reach the dryer vent (Brice had to use the 20 foot ladder to reach mine) but that was clearly spelled out in the preliminary estimate given to me on Friday. I am very happy with RES and both of my dryers are working great now and don't require 2-3 cycles of extra time to fully dry a load! I will definitely use RES again in the future for all of my dryer vent cleaning and heating/AC needs! read more

Tra, David and Brice have been great always professional and on time great team great service. Have been using them for my previous home and now current. read more

Bought a new home and wanted a review of our system. Luckily found Res Express Services on Yelp and had Majed (who we will ask for every time) stop by for the Clean and Check Service. Majed was professional but also fun to talk with. Very personable and a strong communicator who answered our many questions as new home owners and took the time to educate us on our system. Can't recommend enough. We'll be return customers. Great communication, pricing, and staff. What more do you need? Thanks Majed! read more

Have been using RES for annual HVAC inspection for 3 years now. They are very easy to schedule on Yelp. More importantly their technicians are highly professional and efficient. I remember one time the technician pointed out that my indoor unit might be very dirty inside during the annual inspection and he went above and beyond to took it apart to see it. It did turn out to be very dirty covered with mold. I then approved him to perform a wash. After that, my intermittent rash/hive on skin never came back. All in all, highly recommend RES! read more

Came back to a hot house from a trip. Was able to get someone the next day to take a look. They quickly found the issue and fixed the problem. Technician Santo was great- very professional. I've gone with them several times in the past for routine maintenance. Highly recommend for any of your HVAC issues and semi annual maintenance for your unit. read more

RES replaced my heat pump a couple of months ago and did an excellent job. I couldn't have been happier. I would give them 6-stars if that was possible. I've had David taking care of my HVAC issues for the last two or three years. I ask for him every time I call to make an appointment with RES and would highly recommend him. He is the best HVAC technician I've used in my 8 years living in Fairfax. read more

RES did a heat pump and air handler install for me. Majed, Rob, and Dave are a great bunch of guys. Their install work is A+ and the price was over $2000 lower than another company's quote. So here's why I'm happy with this company: - Everyone was courteous and very professional, from the lady who answered the phone to the technicians who did the troubleshooting and the install. - Punctual. Everyone showed up at the beginning of their time windows with texts and phone calls before arrival. I took a day off with another HVAC company who showed up 1.5 hours after their time window, as I was headed out with my family for dinner. - Answered all my questions. I had a lot of technical questions and all questions were answered without talking down. - Great work. These guys installed a better P-trap with a clean-out port, replaced copper line insulation, and re-wrapped the outdoor electrical lines. I didn't ask for these and would have been happy without these, but they did it anyway without any price increases. So in summary, I couldn't be happier. read more

Brice and TJ were very thorough and did a superior job. They went way beyond call of duty. I highly recommend this company. read more

RES Heating & AC responded within 10 minutes of my request and scheduled an appointment for the next day. Technician Rob arrived on time and was extremely friendly. Rob diagnosed the problem without issue and replaced our damper within 30 minutes. Would definitely recommend. read more

R E S was prompt in the response, and on time! (Early to be exact). The technician Maged, was very professional, concerned about my problem, thorough in his assessment, and made sure all was taken care of when job was completed! HIGHLY RECOMMEND R E S to anyone in need of HVAC service read more

My experience with RES was hands down a great experience from start to finish! Very professional and reasonable pricing

The technician came out and was able to assess the issue and fix the issue relatively quick. He did such a great job that we signed up for their yearly maintenance program. read more
