Get matched with top geothermal heating or cooling system installers in Arlington, 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."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"The technician (Shammion) arrived on time and spent time listening to my concerns and answered my questions before proceeding with the work. Shammion has serviced my furnace and a/c unit previously, and on each occasion he has spent time informing me how various parts of my HVAC should work and what I need to do to get the most from the systems. On this occasion, Shammion instructed me on how to use my new thermostat and how best to keep my condenser coil clean in the future. The work was done expertly and in a professional manner, and I highly recommend Shammion and McCrea Heating and Air Conditioning."

"they are an excellent installer"

"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."

"Trevor and his team are top notch.  From the time we met to review our project to completion he was very responsive.  The day of installation the crew showed up at approx., 8:30 a.m. and it was a HOT day, we anticipated a two day install, but because it was hot the crew stayed until almost 8:00 p.m. that night to complete the entire installation.  I have already recommended Trevor to a co-worker who has used him also.  You can't go wrong with Trevor and his team they are all top notch and professional.

"I closed the deal with Julian on late Tuesday night and the team was able to do the installation the next morning! Jesse gave me the details on the team as the ink was drying. They arrived on time first thing in the morning. Dan, Cal and Greg were a great team that stayed active all day. Seriously over 12 hours! They installed a new Hot water heater and an 18 Seer Lennox Heat Pump with Honeywell Humidifier and Honeywell Home Thermostats. My 17 year old system was tightly packed into the basement. I think the basement was built around it. They replaced everything...ducts, hoses, fuses boxes, wires and pipes. Everything was insulated and finally brought to code with new sensors and alarms. After working all day, they ended the evening cleaning up and taking me through the system in great detail. It has only been a couple hours but everything is running great. I talked to several vendors when making my choice. I liked several of them and they dealt with my silly process. Julian was very thorough with his pitch. He told me about the factors that differentiates them from the others. I believe I made a great choice. Merry Christmas!"
