"As a new customer, I was surprised and pleased that the service could be performed on the same day I made the request. Mike was very thorough and professional, and provided a clear explanation of our system and new wi-fi thermostats. Everything was done efficiently - I am looking forward to having Grove maintain our system on our annual maintenance plan."

"The company was responsive and provided excellent service at a competitive price. Our old A/C and furnace had to be replaced in the heat of the summer. Mr. Douglas was quick to respond and provided a prompt estimate. He meet all promises for scheduling installation, removing the old equipment, and a quality installation of the new equipment. He followed up to insure the system was functioning and that all was well. We were completely satisfied with the new system, the installation and the customer service. We highly recommend this firm!"

"I found Edwin on HomeAvisor/Angie's List. We were having some heat issues and wanted to have some basic maintenance. Edwin 'had extensive knowledge about each of our systems, and was able to troubleshoot and provide us with various courses of action. The attic heat pump was replaced and he was very fair with his prices. They did an excellent job, and sympathizes with his customers. He replaced the system on a Saturday."

"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."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"We returned from vacation on a Saturday night to find out that our A/C system had died on us while we were gone. I put in a quote request with JDL and someone contacted me within about 30 seconds of my request. A tech was able to come out on Sunday to assess the situation. Ire was extremely courteous and professional, explaining everything along the way. One minor problem was that we needed a new motor (which died while Ire was here) and they had to order the part, which he said they would do first thing Monday morning. While they did, it was going to be another day before it arrived. I asked if there was something that could done, but unfortunately they needed to wait for the part to arrive. A bit later, Ire called me back to say that they were going to drive way out of the way to pick up the part and get someone to our house later that day, avoiding both a large overnight shipping fee and another brutally hot night in our house. Isak showed up and was courteous and professional as well. He explained the work and explained that our system was working, however inefficiently. He explained how we could fix the issue, and laid out the costs for us. We had to decline as it was out of our budget, which Isak completely understood. I'm not sure about other reviews, but at no time did I feel pressured into buying a product or doing something unneeded. I really appreciate the work they did, their customer service approach, and their overall knowledge and professionalism. We are likely to hire them back based on this service."

"Moises, who is the owner is AMAZING!!! He took a smaller sized commercial job for me and found the issues right away, when several other contractors were not able to. He is very professional. His proposal was very throughout and his pricing is very competitive. He was able to schedule the repairs in less than a week from his initial visit without a service contract in place. I m a property manager and I plan to use him a lot more frequently for my residential and small commercial jobs. Excellent contractor!!!!"

"Outstanding! Had multiple issues with an aged HVAC system. We didn't have cooling or heating. HPC Services responded promptly, diagnosed the problems and expertly repaired the issues while explaining exactly what happened and how to maintain the system moving forward. Great coordination and teamwork from their entire team. We would not hesitate to use this company again!"
