Get matched with top geothermal heating or cooling system installers in Ashburn, VA

"Polar Bear offered a competitive quote, and what seemed a good solution for a somewhat tricky roof install for our AC. Problem is that we asked for a higher ton unit, fearing their initial recommendation would not be strong enough, but they did not follow through on that and installed a smaller unit. Lo and behold the AC does not work sufficiently for our home. They say it is because of poor duct work in our older home. That may be part of it, but the system cools worse than our old one did, before it conked out. After spending $10k on this system just a couple years ago, we just spent ANOTHER 10k for installation of supplemental AC systems (by another company) so our house can actually make it through the DC summer. Now our main floor cools great, but the upstairs, which relies on the AC system that Polar Bear installed, still struggles. I've had Polar Bear come out multiple times to see there is anything they could do to make the AC work better, and other than top up coolant, they haven't offered solutions. I'd not use them again, had more positive experience with another company that I just also reviewed here."

"It took a few hours to set up. After I figured out the Ecobee thermostat I was able to successfully program it. Technicians are considerate and aim to please."

"Great company! They've been super responsive when we've had questions or concerns, and deliveries are frequent enough that we never have to worry about running out of heating oil."

"Aside from installing a new Carrier gas furnace, they installed a state-of-the-art thermostat. The comfort specialist, Chris B., was very responsive and helpful in helping me decide what to buy, as well as providing help after installation. The two installers, Chris M. and Justin B. were very personable and very neat during removal and installation of the furnaces. Overall, very satisfied. Very commendable job."

"They are thoroughly knowledgeable about the WaterFurnace system, and worked promptly and efficiently. They ascribed the failure in the air coil to the poor work of the initial system installers, not to the product itself. This makes sense to me."

"We had a 20+ degree temperature difference between the finished basement and the upper level in our recently purchased home.  We had been using modern mechanical for a few years for annual hvac inspections in our previous home but that system never really required much service.  They have always been professional, punctual, and have a problem solving attitude.  We had them come out to provide recommendations and pricing for installing a new zone.  They provided the following three options: manual dampers, electronic zoning board with digital dampers, or install a completely separate system for the upper level.  The second choice is relatively new technology and they highly recommended it because it cost 50% - 75% less than installing a completely separate system and would have the same effect.  They followed up with a written proposal in 24 hours and had the system installed only a week after signing the proposal.  When the crew came to install it they were professional and polite.  The system has now been up and running for several weeks and works perfectly.  We highly recommend this company and the system/technology that they used.

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"Isak was of great help in servicing our 15 y/o forced air and heat pump furnaces. He described every step of the service, taught us how the units work, and where to look for early failure. Isak also helped install and properly program our Nest thermostats so we have an efficiently running house and HVAC system. Would highly recommend to anyone looking for help!"

"Great -- they call to set up the appointment, talk to me to choose a good time for both of us, call to say they're on their way.
Very thorough, they answer all our questions regarding our furnace, AC, humidifier, everything.  We had them install the whole thing for us back in 2007.

"I had Premium Home Services install a new oil heat furnace and I couldn’t be happier with the result. I am a new resident here and discovered that the old furnace had rusted and was leaking fumes. They came right out and did an inspection and then made recommendations. Since I am a senior on a fixed income, I was happy that there were many options and that I was able to chose something affordable. From the ease of financing, throughout the installation and final visit, I interacted with quite a few folks at this company and everyone of them were pleasant and professional. I highly recommend this company and their stellar service! Thanks Premium, you all gave this old gal a much needed good experience!"
