Our furnace crapped out , at the start of the cold weather. I couldn't get a repair appointment from anybody with less than a two-week wait. A friend at work recommended AirTech, and said he'd had a great experience. I checked him out here. The reviews looked amazing. I called Boris. He came the next day, on Saturday, to look at the situation. I wasn't home at the time. He spoke with my wife. My wife knows nothing about house stuff. I was sure she was going to be overwhelmed, or that the guy would have tried to sell her his most expensive stuff. Instead, Boris took her through the options, and wrote out a quote on the spot. The price was great. I was a little reluctant to go with a Goodman furnace, which is what Boris sells, but looked into them and they had mostly good reviews. He came and gave us the estimate on a Saturday. I called them and said yes on Monday. By Tuesday, his installer was here with the furnace. They did a fantastic job. The install was neat, fast, really professional, and they walked me through how to work the furnace and humidifier. Another thing: they didn't have the warranty with them when they did the install. Boris said he'd put it in the mail. I was sure I'd never see it. (Can you tell I've had bad experiences with other companies.) Two days later, there it was. Boris even followed up on the phone and by email to make sure we were happy with everything. I've never experienced such good service from a home service co. Never. I kept thinking there'd be a catch. There's not. These guys are just great. I wouldn't consider going with anybody else.
