I've used Carlson Heating & Cooling twice and have been very satisfied both times. In 2024, I had…read morethem inspect my furnace and AC. 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 needed to call him back and he came back to fix it after his day was over. A part needed to be replaced. He used the service charge towards the price of the part. His work is really quality. Very conscientious. Will be calling him again!!

I went down the line calling several HVAC companies, most want you to 'leave a message' on our first single digit temp day and it was cold in here. Some called back later in the day, one after many hours called and said "we can't fit you in today". He answered first call and was out within a few hours. I am fairly new to the area and was nervous about finding the right company and thank goodness I did! I have him in my contacts for future should I need help. Thanks so much!!!!!!

Talked with what seemed like the owner on the phone. Said he's been doing this for a long time and…read moreconvinced me I shouldn't be doing a recharge of my system on my own. Be careful, he talks a good game. He said he'd show up the next day. He didn't. What he did do was make excuses why he didn't show up or update me. He'll make it seem like he was working a job or doing things "right" for other customers. So you think about giving him a break. DON'T DO THIS! He claimed he was working till midnight on a job. The next day he said all the right things and apologized. He then wanted me to pay him cash, no checks. He said he would give me a discount for not showing but it had to be in cash. He claimed he was going to show up in the afternoon and then didn't. Then claimed he would show up in the evening and then didn't. I didn't have AC on the hottest days of the summer because I trusted a sticker placed on my AC unit. I read another review on this company and it was pretty terrible. I've met scammers before and this guy is a classic scammer. Worst customer service I've experienced.
