"I am an engineer and I know everything about air conditioning. I could do the installation myself, but I do not have a permit to work with some freons, and I do not have all the required tools, so I had to call a HVAC company to replace an old 2.5 ton heat pump system (that used R-22) with a new 2.5 ton heat pump system (that uses R-410A). The freon compressor in the old system had a short circuit to the ground, but because of the R-22 phaseout I had to replace the entire system rather than just the dead compressor. I contacted 13 companies that work in my area. 9 of them told me that they were very busy and could not take new orders. 4 companies sent salesmen who gave me price estimates. Three of the four price estimates included items that were not necessary, which is what pushed the prices up. When two people (Debbie Thomas and Ron Thomas) from Maryland Heating and Cooling showed up, they started to discuss with each other (in my presence) which items I do not need to replace; this would save me money. In the end they decided that none of the existing duct work needs to be modified and that the old copper freon lines are in good shape and can be re-used, all the wiring and fuses need not be replaced, and the old thermostat is perfectly fine. In the end they came up with the lowest price; significantly lower than the three other offers. Furthermore, they were able to do the installation on the second day after I signed the contract and paid the deposit. I was watching them while they did the work, and I am confident that they did everything right, because I understand exactly what they were doing and why. In other words, they did not cut any corners. And they were completely honest with their price estimate. I was very impressed. I can recommend this company."

"While I was extremely happy with my existing local HVAC company, I made the difficult decision to trust my gut and go with Grove. The Salesperson, Garrett, knew his material. He understood exactly what I wanted to do with the new unit and adding additional zones. He spent the time to explain the pros and cons of each unit and how the design and technology worked with the new features and designs. He even helped explain and clarify issues with other quotes I already had received. I was leaning towards a Carrier unit with another company, but after meeting with Garrett he gained my confidence. I decided to go with the Trane Heatpump unit for my upstairs replacement. I also had them re-configure the upstairs ducting into two zones. Garrett worked to beat the best quote I had. The Grove installation team was top-notch (very professional and hard working). Not once did I see them sitting or standing around. They worked non-stop from the time they arrived on site to the time they left. When the installation was completed, they cleaned, swept, and vacuumed the areas they were working. After the installation, I received two follow-up calls to check on how the unit was working and whether I had any questions. The zone installation and new unit has made a significant improvement to my upstairs rooms. Completely satisfied and would definitely recommend Grove to anyone needing a HVAC contractor."

"I HIGHLY RECOMMEND HVAC Superior Solutions Inc!! They came over to diagnose my AC problem on very short notice. I decided to get a whole new system and they took great care in all the details and worked overtime to get the job completed. I am very satisfied with the new system and with the great customer service."

"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."

"The Buric team did a great job of installing two new HVAC systems in our house at a reasonable price.  This is a family run business, the owners of which take pride in their work and pay attention to detai. The Buric team was also able to add zoning our systems, where other contractors had said this would not be possible.  The work was completed in a timely fashion, and the team cleaned up nicely after itself.  We had two babies in the house, and the team took care not to disrupt their sleep schedules."

"The technician was punctual, knowledgeable of a myriad of products and services related to my home HVAC system. He was cordial and answered all my questions accurately. Where needed, he provided guidance and advise. He's work was done in a timely manner and without any mess. The workmanship was excellent and everything works properly since installed."

"One of my AC compressors was not starting correctly every time. If it did start, it would run fine, but on hot days, when it would cycle frequently, (i.e. cool to target temp, stop, temp would heat up, thermostat would send signal to restart, and eventually the compressor would not restart). I don't remember the exact explanation, but I think there's a small fan linked to the capacitor. The fan provides some cooling to the capacitor which is stressed at startup time. Eventually the capacitor burned out because it wasn't getting its appropriate fan/cooling. First, this is a pretty specific problem. I'm fairly technical myself, and my father can fix anything. We had isolated the issue to the capacitor, but could figure out why it had failed. This is a large home and the large capacitor, so it really was a job for a professional -- capacitors offer plenty of opportunities to electrocute yourself pretty severely if your a "do-it-yourselfer." The No-Frost tech diagnosed the problem within a few minutes and explained it in detail. I called my old man to see what he thought, and confirmed that would definitely explain the problem. Second, the appropriate replacement part was an all-in-one capacitor/fan combo part specifically made by the vendor. Because my unit was a larger-than-typical unit AND these guys rushed out pretty much same day (or next morning -- I think it was a Friday going into a 95 degree weekend). The tech didn't have that exact part on his truck. He gave me two options, he had the same size capacitor and fan unit separately, so he could merge those together and get the unit functioning right then and there, or he could order the part and come back some time the following week -- he called the warehouse and they didn't have it in stock (my compressor is large and 10-years old). Given the weather, and everything else, I had him build the setup I needed, took him about 20 minutes to link the fan and capacitor together and the AC unit was humming along again shortly thereafter. I loved that he took the time to explain the problem in detail. He could tell i was "tinkerer," yet he was very politely patient with my ignorance (I had no idea the capacitor required its own cooling). I loved that he gave me the choice on waiting for the vendor's "officially sanctioned" part or just getting the unit working, and that he took the time to explain why this wasn't a risky workaround. I gave him a nice tip and emailed my neighborhood HOA email group the contact details as a reliable, trustworthy and well-priced service provider who will always go the extra mile for the customer. These guys fixed my furnace a year earlier when I nearly burned my house down by not paying attention to my intake... Would and have definitely recommend these folks for any HVAC needs."

"Carroll Mechanical delivered a 10/10 experience, from start to finish. From the first call, the Carroll Mechanical team demonstrated that they were knowledgable, ethical, and customer-first. First, they offered to help me troubleshoot, and they gave me some great tips that allowed me to try and fix the problem myself before they made a service call. As a not-so-handy guy, I realized that I needed the pros, so I requested on-site help. They immediately offered to come over on the day and time most convenient for me, and they spent time with me walking through the pros/cons of different HVAC options. Ultimately, the team explained the pros/cons of different remediation options, offered me an extremely competitive quote, and was transparent all along the way. I moved forward with a system replacement, which they were able to accommodate the same week(!!). The Carroll Mechanical team was timely, detail-oriented, and respectful of my home, and the HVAC system was installed as expected."
