HVAC reviews in Sterling, Virginia

Daniel had serviced our HVAC, and I've even sought out his advice on related issues. He has always been responsive, professional, and kind. We would not hesitate to use him in the future for our heating and cooling needs.

I have used Daniel’s services several times for Heating repair, AC repair and maintenance. His work is exceptional. He responds promptly, works diligently, is trustworthy and reasonably priced. Highly recommended.

This is by far the best HVAC company I’ve found with in NOVA, and I’ve worked with a bunch both at my personal residence as well as my rental properties. Daniel and his team are always responsive, and most importantly, don’t try to upsell unnecessary products and services. I’ve always received solid repairs at a fair price.

Daniel is amazing - he takes the time to explain exactly what he’s investigating / repairing, and his professionalism shines through with every step. We had an issue that needed addressing quickly with a little one in the home, and he did a complete system evaluation that resolved the issue, and gave us pointers on maintaining the health of the system and things to look out for in the future. This is absolutely the contact you want to keep handy in your phone for the “just in case” emergencies, as well as any future upgrades you may have. Give Daniel a call, he’ll get you squared away!

The first thing you will get to notice about Daniel with DC Heating & Colling is that he is meticulous about his work. He demonstrates outstanding work ethics and takes pride of his customer support. When we first called DC Heating, the HVAC system was not cooling enough; unable to counter July hot temperature. Daniel came and checked all pressure and temperatures. He quickly identified a major flaw in our HVAC system that existed for years and was contributing to poor system performance: The Air Handler was missing a vital part called “Thermal Expansion Valve or TXV” that should have been part of the manufacturer release. Surprisingly, our system was running without Thermal Expansion Valve since first installation 4-5 years ago which explains why our thermostat was never able to satisfy the desired indoor room temperature and the system was continuously running. To make it short, Daniel installed the new needed parts, performed final system checkup and ensured the system is performing to specifications. We could not be happier and you will too.

Daniel has always been responsive and professional. Imagine...someone who communicates when he will be there and then confirms when he is on the way. If you watch him work, you quickly see he is very knowledgable and meticulous. Prices didn't seem unreasonable.

Daniel was amazing. Honest, professional, and timely. I was lucky to have been referred to him from a friend last year. He beat the prices of other companies and installed my AC unit quickly. If you are looking for an honest dependable person doing maintenance on your HVAC units - I would highly recommend Daniel!

I would highly recommend Daniel to anyone looking to get a quick and honest quote on your HVAC system. He came within 2 hours of me calling when my home's heating system broke down in December. He walked me through exactly what was wrong, and provided a quote to repair the system and a quote to replace it. Both quotes were far less expensive than those from multiple other HVAC companies in the area. I contracted with Daniel to repair the system and he gave me recommendations on how to keep the system healthy until I was ready to replace it. Daniel is someone you can trust to take care of your HVAC system and charge you honestly for it.

On time, quick and efficient! Will definitely use them again.

ASG was very responsive when the capacitor went out in our AC unit. Very polite and easy to work with! Highly recommend!

We were waiting for the new compresor for a month, today was the "day of installation," after of 4 hours the technician decides to order a missing part :START MOTOR at the last minut, so obviously he does'nt know how long it will take to have that part
Unprofessionalism and lack of expirence

I cannot say enough good things about ASG, and about Tyler in particular. Nicest guy, knows his stuff, and busts his butt to help you. And the pricing is more than fair as well! He’s been a life saver - called him in for some issues with our plumbing, and ended up calling him back to help with some other projects we’ve been putting off for years. I only wish they did more than HVAC and plumbing because there are so many other things to be done around our house!

Excellent Service and Product. I just had a $9k Bryant Heat Pump and Air Handler installed by ASG. I researched other companies and the price all in was just about right. No hidden fees and proposal amount was exactly what I ended up paying. It was a tough install for it was a really tight space, but the very professional crew handled it extremely well, answering all of my questions along the way. I highly recommend ASG for both service and product!

Advantage Service Group did a full toilet rebuild for five toilets in spring 2023. I asked specifically what would happen if there was an issue at the time of purchase and was told there was a 1-year warranty--if there were issues, I could get the toilet fixed.

6 months later, 2 of the toilets now run continuously. When I called to ask for a free repair, I was informed that ASG no longer provided plumbing services. When I said that was understandable, but I expected either a refund or for ASG to pay for another plumber to provide the repair, they declined. Without sending anyone to assess the problem, they asserted my only recourse lies with the manufacturer of the parts. Upon being pressed, he did indicate that if they still had a plumbing service, they would have sent someone out to assess the problem but no longer felt they had any obligation. Had I known this, I would not have used ASG because I specifically wanted the parts (and their replacement if need be) to be warranted for 1 year.

ASG does not stand behind their work nor the parts they select to complete their work. Anyone looking for a professional service provider, who will fix problems arising within a reasonable time frame should look elsewhere.

I had troubles with my AC come to find out my condenser unit wasn’t working. I called ASG and was greeted by a friendly voice, I told her what the issue was and she was very knowledgeable. They were really busy that day but managed to squeeze me into the schedule which was awesome! The tech gave me a courtesy call and let me know his ETA. The tech showed up as discussed. he then quickly diagnosed my AC unit and found out I had a faulty contractor. I was ready to bear the heat for one more night being used to hearing we have to order parts I know we all heard that before, but to my surprise! He was like a mobile parts store! And he quickly got me up and running! I’ve been happy every since. Thank you guys! With excellent service and knowledgeable techs! You have a long time customer!

Highly recommend ASG for HVAC service of any kind. We have used them multiple times over the years and have never been disappointed. They are quick to respond and always fix the problem the first time out. Our last service tech Rusty provided exceptional service after hours to replace an outdoor fan motor when it was 100 degrees outside. Rick and the gang are first class.

First time I used A.S.G and it was a great experience. Got my HVAC unit replaced at our house. Very impressed. Corey was my tech and he was thorough, knowledgeable, efficient, courteous and an overall pleasure to work with. I signed up for the semi annual agreement and look forward to proactively caring for my heat and a/c units at my house. Thanks again!

Go with ASG for all your HVAC services and maintenance. Their service is the BEST and they provide top-notch quality work. We replaced the upstairs and downstairs units with ASG and are truly happy. Rick, provided awesome customer service prior to and subsequent installation - super fast response and unit registration. Corey and Jordan installed the new unit with superb quality work - they even cleaned up the basement area after the job was finished. Also, they provided detailed instructions about the new unit. I highly recommend their service!!!

Have been using ASG for several years now. Always impressed by their dependable, fair-priced services, as well as their courteous and responsive staff (Chris and Rick) and technicians. Cory, who has visited us before, did another great job, this time replacing a dead compressor on an HVAC unit. Special kudos because he also noticed that for all of our HVAC units, the fans were set to blow too strongly, making them both noisier and less efficient, so these were adjusted too. Would 100% recommend as I've done for others in our condo building.

Prompt and friendly service

Fantastic service and customer interaction
