My wife and I bought an older fixer-upper with a 25+ year old furnace and AC unit. The AC limped through the summer months and barely worked, but once we started running the furnace, it was obvious that there was a problem - the unit was very loud and vibrated horribly. Based on positive HomeStars reviews, we called Richard from Coretemp to assess the situation for us and see if it would be worth repairing the furnace. Richard picked up the phone immediately and even arranged to drop by that same evening. Within ten minutes, he identified several problems including a vent motor that was just about toast - unbalanced and had a bad seal. He also discovered a cracked heat exchanger, which was a serious safety issue requiring the gas to the furnace to be shut off. I have to admit that I was a bit skeptical about the cracked heat exchanger, but he even inserted a special camera right into the furnace's internals to confirm and show me. Sure enough, it was badly cracked in several places. This would obviously be an expensive repair, so we decided that we'd just replace the furnace. Richard explained the problems to us in great detail and spent time going over our options. What I liked most was that he was very low-pressure and didn't push us at all. He simply gave us our options, was very patient with my many questions and even encouraged us to do our own research and compare pricing. We decided to stick with Coretemp because of their fair pricing, reputation, Richard's experience, and the fact that he doesn't sub-contract out any of the work. In the end, we decided to replace the AC and humidifier as well as they barely worked and were on their last legs. We really liked the higher end, high-efficiency Lennox gear that Richard showed us (especially the SLP98 furnace, which is awesome). After giving the go-ahead, Richard was able to schedule the install just a couple of days later. He arrived on time with two other technicians, Eric and Nolan and were all very hard working, professional and very friendly. After about six hours, they had the old units removed, everything installed and very thoroughly cleaned up after themselves. Richard even took the time to show me the cracks again from the outside once they had the old furnace disassembled. Richard asked us questions every step of the way to ensure everything was installed and positioned in the way we wanted, including the AC unit and drain/exhaust piping. Their attention to detail was very apparent, and although I'm not an HVAC expert, I could definitely see that they did quality work. Once finished, he spent time going over the operation of everything, how to send out for the rebates, and gave us a demo of the really nifty icomfort touch-screen thermostat (which is also awesome). We couldn't be happier with the furnace and the AC unit - what an incredible difference - and very quiet too! Overall, I'd have to say that we were extremely satisfied with this experience from beginning to end and would not hesitate to recommend Coretemp to anyone looking to get their furnace or AC replaced or serviced. Thanks again Richard!
