On first start of my furnace for the year, I had some issues. I called these guys and told them…read moreabout the short cycling and failure to sustain a flame. They told me they were 99% sure what it was based off how I described the operation and, unfortunately, I'd most likely need a new furnace. But they would send someone out next day to make sure since it was getting cold out. They came out next day and ran through the test with me, explaining what was wrong. We determined I did need a new furnace, why my current one couldn't be repaired, talked options and made an order. They were back out the next week, in peek season, to install my new furnace. I had Heat just in time for the cold snap. Everyone I dealt with was professional and honest and I was so impressed I chose them to do all the heating and cooling work on my new construction the following year. I see negative reviews and cannot even imagine that these are the same people I dealt with.

I thought great I'd use the $15 coupon on postcard too that they offered me. Then after work was done told it was $84.95 plus tax and the coupon for $15 off I couldn't use. Juston said service was regularly $94.95 and that was the $15 off I said no $15 off would be $80.00 not $84.95. Juston said to call Wendy I did she said service was $99.95 the $15 coupon was for new clients only. Wendy said the coupon was sent out to me as a reminder to call in for service. Juston the technician was a great guy very personable and gave me tip to keep unit clean. Juston said yes he ran into this problem all the time that he would talk to Wendy when he got back to his business. I signed it begrudgingly but I thought this is a bait and switch I called my credit card company I'm disputing it. I've loved having them out and they do great work and are reliable business. The last visit they matched the coupon price of a competitor. The coupon says not valid with other offers but not saying what that is? Definitely not transparent in their business practices. I told Juston I'm putting this up on Yelp. Juston then said he'd talk to Wendy. If they've had this problem with many other customers then why haven't they changed it. Wendy could of mentioned this over the phone.
