I reached out to Edgar again and he was out the next day and got us back up and running. Both Edgar and his apprentice were very professional and they made sure to explain the work done.

On the coldest night of 2019, in the middle of the Polar vortex, with -20° temperature and -50°…read morewindchill, my furnace decides to go out. Never on a mild day... of course not! We called several companies to come out and repair and none had techs available. We called a friend to come take look at our furnace in the middle the night as we scrambled to buy all of the portable heaters that Walmart had. He came by, he is a great handyman but could not get it working. The next day, a reputable company came out to give us estimate for repair/replace and the tech/sales guy was great. But the prices... we were quoted $1,000.00 -$1,200.00 for repair, with no warranty on the furnace, just the part replaced (it was either the computer or the heat exchanger. Either part was upwards of $800 for the part plus install and not sure which one it was so we may have had to do both!) We also received a quote for a new one for $5,300.00!!! Our handyman recommended we call Edgar Diaz. He came right away and quoted me LESS THAN HALF of the above price for the same HIGH EFFICIENCY FURNACE (92% efficiency) for a Bryant furnace with full factory warranties. I looked it up in the internet and it had just as good reviews as the TRANE that we were replacing. We gave him the OK and had a new furnace installed and fully functional and WONDERFULLY warm house the next morning! Edgar is an old school gentleman. Soft spoken. Honest. And delivered on his word. Extremely happy with the work, install, and equipment installed. He even re-wired the humidifier and water pump. I highly recommend Edgar. Restores faith in honesty on the trades.

TLDR; absolutely recommend Wanktuck for any HCAV work…read more We purchased a home several years ago and were aware that the mechanicals in the home were old, but decided to get every bit of milage we could out of them before we finally bit the bullet and replaced all of our systems. We gathered a few proposals before moving forward and Wantuck went the extra mile to get us the best, most competitive pricing out there. Their people are all incredibly nice, punctual, clean and really care about the service they deliver. I rarely write reviews but having read through some of the older ones decided this was needed because their rating is not reflective of their level of service.

After being fleeced for $350 for a non-repair of our air conditioning, we called Miros. He…read moreascertained that the previous company had charged us $350 for freon installation when a massive leak in the system was immediately apparent when attempting to inject freon into the system. Miros spent several hours carefully repairing the leak, flushing the system, and recharging the freon, all for slightly more than we were charged by the first company. We are cool and comfortable. Miros is honest, prompt, and fair. If you have a heating or air conditioning problem, don't be tempted by websites, 800 numbers, or the allure of being able to pay by credit card. Dust off your checkbook and call Miros. You won't be disappointed. P.S. Miros wrote up a report which we faxed to the first company. Because of his explanation of how the massive freon leak was immediately apparent and would've been known to the first technician, our entire payment of $350 was refunded. Thanks again, Miros!
