I found Cool Flame on Home Stars when we needed our furnace cleaned. Dwayne returned my call promptly and Jeremy (?) did a great job, quick and clean. When I asked him to check out the humidifier that comes with the furnace, he found that it was not working at all and probably hadn't in years. The solenoid needed replacing. He got the part and it's been working well since. My husband and I have found this has made a big difference in how dry our skin is during the winter months and are grateful the problem was repaired. We used Cool Flame again for a small job a couple of months later and will call them again if needed. Great friendly service at a reasonable price.
