"They went over and beyond to do things right which includes fixing things that were done poorly previously. There was a bush growing between the house and the AC unit where it shouldn't. I asked if he could let me know when they pulled the old unit so I could remove the bush. He took care of it for me. Down by the furnace, they fixed the slot that the filter goes in. I'm very happy with their work."

"There is no need to look any further than Dr. HVAC for your heating and cooling needs. After my experience with them, I will never call anyone else. I initially called Dr. HVAC when we started noticing some noise from our basement furnace. Steve (the owner) was able to come for an estimate the same day, and we had a new furnace within the week. During the estimate he looked at both upper and lower units and gave us his opinion on what the most pressing issues were, as well as future work we should plan to have done. He also helped troubleshoot a problem we had with a "cold" bedroom, saving us countless time and money for work that ultimately wasn't necessary. We ended up deciding to replace our basement furnace and hold off on the upstairs furnace since it still has some years left on it. On the day of the repair, Steve called ahead with an ETA and arrived on time. He walked my husband through the issues he saw with our old furnace, which was great because my husband wasn't home for the estimate. The removal and install was smooth. Steve stayed for awhile after the install was complete to ensure the unit was functioning properly. He noticed afterwards that our humidifier wasn't installed quite properly (previous owners must have had work done on it) and took extra time to check to see if it was functioning. There was also a plumbing issue with the pipe leading to the furnace drain that was related to work that had been done while the previous owners owned the house. Steve took a couple extra hours to obtain the supplies needed to fix the problem even though the heater was already installed. He went way above what we expected and saved us the cost of having to call a plumber. Dr. HVAC absolutely went above and beyond any expectations we had to not only provide exceptional service and product but also to give us peace of mind knowing that the work was done properly. You can tell he genuinely cares about the quality of work that he does. I have Dr. HVAC's number saved in my phone and look forward to working with them in the future for our seasonal AC/furnace checks."

"Steve is fantastic. The company has veritas in the name for a reason, because heâ s honest. Steve did a few small projects for us around the house and everything was great. There was even one small item I didnâ t know how to fix. Apparently it was super easy and instead of charging me, Steve gave me suggestions to do it myself. Took 10 mins and saved me a bunch of money. This is truth. Hire Steve."

"Very professional repairman. Highly-experienced in working with boilers. Was able to order the part and install it within a week. Checked all my radiators. Saw that I needed a shut off valve for the boiler, which will be done in the future. Very pleased with the entire job."

"Able to squeeze me in, prompt, responsive, followed up the next day. Had issue w thermostat not kicking furnace on so I thought. Noticed furnace kick on/off randomly the last 2years. Woke up w/house temp lower than what thermostat was set for occasionally. Basement very cold, upstairs colder than you would think too. He discovered furnace was overheating and shutting on/off due to multiple closed off vents that he discovered. Very quick to diagnose/resolve. Noticed huge difference the next day throughout the house! Affordable as well. He knows his stuff; took time to explain what was going on , what he was thinking and what he was doing! Thanks Erik!"

"Very responsive and offered options for financing. The Legendary Service Team has a thorough understanding of regulations and offers environmentally friendly suggestions for your HVAC needs. They did a furnace/AC replacement in my home. Their scehduling system texts you when they are in route to your home. The install went seamlessly. They kept all work areas covered and clean. I will use them for all future maintenance needs."

"They were great to work with. They got the work done quickly and were very easy to communicate with. I would recommend them to anyone!"

"After a few years of using other heating and cooling businesses I found Keith, he was always on time and ready to work. We had a few issues with our boiler system that was getting up in age and he said he could fix it but it may only last a couple years so we decided to just replace it. Keith gave us a great quote and was again prompt and thorough on installing the new boiler. We were so happy with him that when we needed AC work he was the first one we called, which we ended up getting a new AC unit as well as it was old and could have been serviced over and over again but now the new ones are more efficient and almost pay for themselves. So when our water heater went out there was only one person to call, Keith was here as usual, quick and clean and no issues. Now we call and have both serviced regularly by him and no more problems and can rely on his work to keep us comfortable in our home. Call Keith if you donâ t want to worry about your homeâ s systems you wonâ t regret it."

"Gus and Jesse explained everything they were doing and noticed the area around my water heater was damp. After checking it, they told me to keep an eye on it rather than recommending immediate replacement. I have already recommended them to friends."

"They respond very promptly. Evenly priced. Very personable and easy to talk to."

"Very knowledgeable, very thorough."

"My heating contractor, Gary was very friendly and helpful. He made a quick diagnosis of the problem and had my furnace fixed in no time. I’m so glad I called. I would definitely call G & R for all of my future HVAC needs.-"

"Very professional, on time, reasonable prices. I would use them again in a minute, and have already recommended them to a friend."

"They came right out, gave us an estimate and completed the job in one week. They explained everything and answered all our questions. They did a great job, put down tarps on my floors and cleaned everything up after. I couldn't be happier."

"We will hire Edd again in the near future for some more projects we are planning. He was fair and did a great job installing our ceiling fan. Very courteous and friendly, and answered all our questions."

"The maintenance guy , his the greatest one!"

"Quick response and accurate work in time."

"I was pleased that they were willing to assess the necessary repairs and agree to a solution that was only half as expensive as was originally quoted and less than a quarter of the cost of other bids we received. But the final repair was still more than adequate."

"Amazing customer service! Explained everything in detail and took their time to clean, diagnose and fix our furnace. I would highly recommend them!!"

"Elvis did a great job today fixing our HVAC and surprisingly charged a very fair and very reasonable professional fee. I definitely will recommend him to family, friends, neighbors.

I lined up annual project for him to tune up and inspect our HVAC to keep it good running condition."
