My mini-split stopped working and I contacted another company. The service person was very nice but not as knowledgeable. And the quote to repair was nearly $2000!

Do Not Use This Company! My remodel contractor used them to…read moreinstall two brand new toilets in my house in August 2017. Both of those toilets needed to be fixed within 2 years, which the plumber who ultimately did the job was quite surprised by. Then, almost exactly two years after they were installed, one of them sprung a leak at the base, indicating that the wax seal needed to be replaced. Again, the plumber was stunned that a seal wouldn't have lasted two years. Each time these things happened, I tried to get GMB to come out. But their phone goes to voicemail and they do not return calls. I left a detailed message this time so they knew exactly what was needed. Still no response. The shoddy installation has now cost me hundreds of dollars. Don't get ripped off by GMB like I was!

After my furnace died, I had my HVAC replaced by Four Seasons. The quote came in lower than two…read moreother local companies. They were on time daily, wore masks and gloves at the start of the pandemic, and were really helpful in explaining the new system to me. Everything turned out well. Even better, a few months later I was having trouble with the air conditioning during some of the 90 degree days in summer (isn't that when all of the AC units die?). Despite the several day wait for an appointment that would have been after the weekend, they came out first thing the next morning to troubleshoot my problem. Apparently the filter clogged up in an extremely short amount of time (long story short, I should have checked that). In addition to coming first thing in the morning, they didn't charge for something that was definitely within my control to fix. Thanks for the great service and for being so nice when I screwed up, I'll definitely be a repeat customer.

Now we wished we had gone with Indoor Comfort for our heating and cooling needs. Highly recommended.

I messaged my favorite plumber (Kennedy Plumbing) asking if he could recommend someone for a furnace repair ... he immediately recommended D&G.

He knows his craft. No wasted motions or steps. Within 15 minutes the root cause was identified and repaired - a safety sensor was dirty. Add D&G to your Contacts app ... I have!

Called around 8 a.m. after discovering that our gas furnace had stopped firing up overnight. A very polite real-life person answered after just a couple of rings (no prompts or automated options required). She said a technician could come same day between 1 and 4. He arrived at 1:15 and diagnosed the problem quickly, a dying circuit board that was not providing consistent power to the igniter. He quoted the cost of replacing - around $450 but was concerned about replacing such an expensive piece on a furnace that had perhaps already exceeded its life expectancy. It was a honest assessment. My husband and I had been expecting both the heating and a/c to go out for the past few years, based on their age (about 25 yrs) and well-worn condution. He knew some tricks to get the furnace running but it failed again that night, consistent with the nature of the problem. Thankfully, the salesman John - 35 yrs on the job, was scheduled to visit that morning. He helped us explore various options and discussed our needs and requirements. He listened, evaulated and eventually sold us the least expensive model with no pressure to buy the high-end units. Such a pleasant experience! Incredibly, installation was the next day. Mike, 15 yrs with the company, and Andy, with around 5 yrs, worked as a team to install a new furnace, a/c and thermostat. They used drop cloths to cover the floor where they would go in and out with equipment and they swept up any debris they created. We are very pleased with the process, results and each employee that got us there.
