    I got a few bids for my HVAC project, and HVAC & Insulation Gurus stood out right away. Their rep…read morecame to the job site, carefully looked at the situation, and came up with a smart solution for relocating the air return vent, which was exactly what I needed. Other HVAC reps I spoke with didn't want to help or even suggest rerouting ductwork to make it happen, but HVAC Gurus did. It was a complex situation working with the existing structure and a new addition. They did all new ductwork, a new furnace, and a cooling system, but the most challenging part was finding the right spot and successfully moving the return vent from its original location. That's when I knew I needed an expert, and that's why I chose them as my sub. As a general contractor, I value trades that can communicate clearly and coordinate with others on site, and this team did just that. Their pricing was competitive for the scope of work, and the quality matched the investment. Professional, reliable, and solution oriented, I'll definitely be working with them again and recommend them for any HVAC work.

The inspector said we needed an electrical permit as well and it took MANY phone calls and another month before HVAC Gurus actually pulled this permit. The first inspection failed because they did not install a GFI outlet on the outside of the house where some electrical equipment was installed. They charged me an additional $650 to resolve what should have been installed properly in the first place. The second inspection because they used flexible conduit from the electrical panel to the ceiling and code requires rigid pipe. They were also cited for using incorrect wiring colors, black wire for HOT line which has to be red to meet building code. This is pretty basic stuff. HVAC Gurus ignored all attempts to remedy the situation amicable and totally dropped the ball. I don't recommend this company to anyone. The workmanship is sub-par at best and they don't stand by their workmanship and their customer service is the worst! I also learned (the hard way) it's never wise to pay any contractor in full until permit inspection has passed. In the end, I hired a qualified electrician and it cost me another $600 to fix the wiring screwup. I would NEVER do business with this company again!

    Great experience--highly recommend!…read more We reached out to EM along with a couple of other companies to inspect our attic and crawl space, and they were the clear winner. We wanted to replace our old insulation because of rat droppings and also improve the temperature difference between our first and second floors, since our upstairs would get much hotter during the summer. Sebastian performed the inspection and was our main point of contact throughout the project. He was thorough, knowledgeable, professional, and easy to work with. The estimate was very fair, and he took the time to answer all of our questions without any pressure. We ended up replacing all of our attic insulation, installing a radiant barrier, replacing some of the ductwork, and adding a moisture barrier in the crawl space. On the day of the installation, a large crew arrived right on time. They did an excellent job protecting our home and keeping everything clean while they worked, and they completed the entire project in a single day. It's been about a month since the work was finished, and we've definitely noticed a difference. Our upstairs no longer gets nearly as hot as it used to, the house holds its temperature better, and our AC seems to run more efficiently. Overall, we had a fantastic experience from start to finish and wouldn't hesitate to recommend EM to anyone looking for attic or crawl space insulation work.

Workers were friendly and thorough with work. Reinstall went smoothly with one follow up visit that was resolved nicely. Very reasonable prices compared to larger, well-advertised HVAC companies. Work was guaranteed.
