"Edwin was FANTASTIC!!! I found him on the HomeAdvisor app after my home warranty company failed to respond to my work order for a broken A/C unit after 3 days. I called him and he was able to provide a same-day appointment within a few hours! When he arrived, he was very knowledgeable, professional, punctual, efficient, and came prepared with all the right tools. I was very impressed with his service and look forward to him servicing my HVAC unit in a few weeks for general maintenance/preventative service. It has been so hot lately that we needed urgent service and Edwin saved the day! I would highly recommend him to others. Thanks so much again, Edwin!!!"

"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 found TriState Home Services on Angies list and contacted them. Since it wasn't an emergency I scheduled them to come out the following day. The Plumber (Chris) did a great job assessing the problem with the leaky faucet and indicated that given the age of the faucet (41 years), he could attempt to repair it but wouldn't guaranty how it would last and recommended that I replace it. I agreed with his advice especially considering the price comparison of repair vs. replace - the price was reasonable. The quality of the work top notch, on time, and as promised. I would recommend TriState Home Services and will use them in the future."

"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."

"IRE YUSUFF from JDL HVAC SERVICES LLC. was Extremely Professional. Serviced our furnace for the winter, checked everything from every wire to every part to air input/output etc... IRE answered every question and explained a part that needed replaced. He showed the old part and it's voltage that was deficient then the new part and the proper voltage for our unit. He was Extremely Professional and Knowledgeable. We even decided to have him/his company to return again in the Spring to service our air conditioning. We found them through HOME ADVISOR and within 10 minutes of me requesting a quote for maintenance/service JDL HVAC SERVICES, LLC was calling me on the phone. They set up service for the very next day which was a SUNDAY. I would totally recommend them to anyone in need of through/excellent service. THANK YOU!"

"Customer service was communicative but not pushy. The technician, Nelson, was skilled, prompt, knowledgeable and above all else honest.
