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.

However, I recently had a horrible experience with him and his team. Our HVAC unit wasn't working and we called Mario and his team to repair. They charged us $2,350 for a few pounds of refrigerant, sealant and 3-4 hours of labor. When the work was done, they claimed that they'd used gauges and detected that the leak was sealed. We sent a $545 payment on June 3 for the refrigerant and labor, a $350 payment on June 5 for the sealant and labor a $1,500 payment on June 12 for the repair of the leak. I asked for detailed receipts of the work four separate times and the detailed receipts were never sent over. On top of that, a few weeks later we had the same exact issue with our HVAC unit. When we called a different repair person, the refrigerant had dropped significantly AGAIN and we were told that the unit was still leaking. We reached out to Mario various times asking for receipts and explaining our frustration. As of today, we've gotten no response, no refund, and no promise to return and look into why the leak that they claimed that they'd fixed was not fixed. All in all we're out almost $2,400 with no true fix to the HVAC issue that we called Mario & his team for to begin with. I'm willing to remove this review or bump up my ratings if I get some sort of response. But at this point we've been waiting for a response and requesting receipts for over a month with no action.
