Thanksgiving weekend. Overnight our sunny, warm late summer became cold, drizzly and dull. I had a houseful of guests due to arrive any moment and my furnace stopped working, leaving the house cool and damp. I called Dave and he immediately had his assistant Don come over to see that I got the best and quickest repair service possible. In a short time my furnace was working, my house warm and comfortable and ready for guests. I can't say enough about Dave and Don, they do their best to get the job done as quickly and with as little disruption as possible. Btw, Dave took care of all this while, unbeknownst to me, he was out of town for his daughter's wedding!. Thanks Dave and Don, you're the best!
