"Grove Heating & Cooling came to the rescue 5/17 after another local company couldn't complete the job. We needed our heat pump/compressor moved for the installation of a patio then reconnected. The "other" company disconnected then couldn't schedule to finish even after giving them a months notice ahead of time. We found Grove and gave them a call. It was after hours and the on-call tech returned the call. He wasn't able to come out that night but made sure to call to schedule the very next morning. By noon we had service to reconnect the heat pump and 3 hours later we were up and running. Everyone at Grove were so responsive and went out of their way to make sure we felt like a priority. You can really tell why they have been in business as long as they have been with how well they treat their customers on top of being technically proficient. Our family is now a super fan and advocate for Grove. Highly Recommended! Mike"

"Perfect! Doug is an expert Plumber that knows private water system. He removed the old equipment and installed the new. Everything is still working great. The work was done almost 13 years ago. We used all Top of the line Gould Equipment. I probably should call Doug to replace it again because breakdowns with the water system can leave you stranded."

"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."

"Edmond responded right away and listened to my explanation of the issue over the phone. It was Friday afternoon and we both agreed the issue was non-urgent so we scheduled an early Monday morning visit. He showed up at 8a sharp as we agreed and he did a thorough check of our AC system. Edmond is very knowledgeable and he explained everything thoroughly. He gave me a couple of suggestions. I’m pretty handy so I’ll try to tackle it myself. He said to just call him if I get stuck and he could either come back out or coach me over the phone. Pricing is reasonable and quality of service is top-notch. I’ll keep them on speed dial and I highly recommend Hecomo for HVAC service!"

"This was only a full HVAC system semi-annual checkup. The tech knew what he was doing and did it. No repairs needed."

"I decided to cancel the repair because of cost. They made a repair that will last for a year or two and I will pay the price when this unit dies. A repair was $1,200 and a replacement was $4,300. Just too much."
