They arrived on time, were professional, and gave my system a clean bill of health--without recommending any unnecessary repairs. Last week, when my AC stopped working, they quickly diagnosed a dead compressor and recommended a replacement. Impressively, they waived the $225 charge for the initial visit and parts. The replacement was completed on schedule, exactly within the estimated cost. The technicians were friendly, informative, and professional throughout the process. They also cleaned up thoroughly, leaving no mess behind. I trust Carlson Heating & Cooling completely and will continue to use them for future service. I highly recommend them to anyone needing a system check-up, repair, or replacement.

I explained the problem. He checked the programmable thermostat, then the furnace, did an electronics test and found some part malfunctioned, a solenoid, I think. He showed me the electronic test and I saw the failure register. He retrieved a new part from his truck, had it installed in less than 15 minutes, rechecked the system and performed another test and pronounced my furnace as being cured...for now. WHAT?? Yeah, he informed me this was usually the part that failed a majority of the time and based on what I briefed him on, he had a pretty good idea what the problem was. Anyway, he cleaned out the dirty furnace, buttoned it up and wrote out the bill. I paid him and he was gone - all in just under an hour....and the house was warming up. Yeaaa!

I called and talked to a few recordings and after about 3-5 minutes got a CSR and then was disconnected so I call back and do it all over again and then get no apologies for the hang up, but I'm ok and they say they'll send it out to a tech....And sure enough about 10 min later I get a call from Mr.Baker he is very polite and fixed the problem in about 5 min. So you would think that I gave this company two stars for the Customer service part on the phone but that would be incorrect, the part that the tech replaced was a ignitor and I was charged $65 for a $16 part and $86 for the service call (which I'm good with because he fixed it quick!). $65 for a $16-25 part online is unacceptable. So I hope you all will find this helpful and stay warm out there because it's cold outside!
