I am very satisfied with his work that I am having him come and inspect and repair (if needed) my air conditioner in the spring. Highly recommend!!!"

"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."

"Got quotes from several companies and they were far and away the lowest price, next closest was almost $2k more. Guys came in and installed dual furnace and free humidifier in a day. Highly recommend."

"Jose was prompt and efficient and did a lovely job. I needed the moldy, very old, hanging insulation removed and taken away. I have already told my neighbors about Jose. When he finished and left, downstairs was spotlessly clean. I highly recommend him. NOTE: I could not accurately list the work Jose did, so I put in foundation because I needed something. This website is flawed,because you can not list what you had done, except in the narrative, and I want people to know what an excellent job Jose did."

"You can't go wrong chosing G&R."

"I hired them to come out and do a tune up on my furnace. They were extremely professional, explained what they were doing and even took a camera to inspect all of the equipment, showing me every step of the way. Unfortunately I had some cracks in the original Furnace (16yr old), and it would be too much to repair. They scheduled someone the next morning to come out and price an entire new system with Furnace, AC (also original), and Ductwork cleaning. They were extremely thorough about our wants, needs, and various options. They wanted to make sure they got it right, and didn't just come in to say "this is how much it is. Yes or no" With the numerous guarantees (including 25% energy savings), and the quick work (from inspection to a whole new installation/duct cleaning in 3 days) this company was a pleasure to work with. Would highly recommend, and they are now our new HVAC company. I really appreciated their all in prices. They quoted everything (tax, permits, etc) and stated that no matter what, the price wouldn't increase. If they had to add or change things, that was the price. Was nice not to be quoted one price and get shocked with how much it REALLY was"

"I recommend this company, very friendly and very good job, willing to help"
