Thank you, KMS Heating & Cooling, for supporting our home with integrity and excellence. You’ve earned our highest recommendation!

I had to have my solar hot water panels removed, because I have to get a new roof. They did an excellent job. They inadvertently switched off my thermostat to my heat and cooling. They came right out and flipped the switch back on, and I was grateful. That's something that I could have done, if I knew about that switch, and they were gracious. Thank you for your assistance with both issues.

We have used KMS for a decade now and they have always provided the assistance that we need.

This is honestly one of the worst companies I've ever had to deal with. I had a good history of them working with me in the past. They installed the original geo unit in my house so I have continued to do business with them just based on familiarity alone. About 10 years ago, we had a misunderstanding about payment method after installing a new external pump. They used the card on file which was expired after I told them to bill me directly and not by my card on file (I was between debit cards at the moment). This eventually resulted in a late payment. Never went to collections. Following year, I scheduled an appointment, tech came over and serviced my geo. After service, he told me he had orders to collect cash payment for the service. One of the few times I actually had that much cash on me in my life. Wasnt happy that fact wasnt disclosed until afterwards, but I collected my receipt and went about my day. About 6 weeks later I received a nasty letter saying that they were going to take me to collections on the payment that I already paid in cash. I call them, tell them I have paid that bill, in full, the very day of service. I was asked to take a picture of the receipt, and send it to them. While doing that, I realized that I actually overpaid (according to their invoice) by $1. Lol. After sending the pic of the receipt, I jokingly told them how i expected that overpaid dollar to be returned to me. Later, that year...I called to have the geo serviced again and was told that they have a no service tag on my address due to late payment. Honestly, I didnt even argue with them. I didnt want to waste another minute of my time on them. These people are clowns. Everytime someone came out, it was always a different person and it seemed like every tech they sent out knew less and less about the unit. I took that all in stride. Despite the high cost service calls. Or the fact that their techs would charge me extra on labor, and even it out by undercharging me for freon (more money in the techs pockets that way but all the same to me). Their record keeping alone tells you how the rest of their company operates. There are better options out there. Willing to bet a high percentage of better options.

Customer service is not good at all! They do not keep you informed on the service they are providing.

Two service trips on the same unit. First trip was by an inexperienced tech who installed the wrong part then finally was able to locate the correct part (maybe) and had his supervisor instruct him over the phone how to connect the part. Second trip was to address the issues that probably caused the first problem due to a heating element coming on during the A/C cycles. That was disconnected after having eliminated all the other possible causes. So now, over $1500 later, I still have to have someone come out and reconnect/replace the heating element. I can promise you it will not be KMS!

Would not recommend. They came out during business hours and stated they fixed my AC unit, but it was not fixed and they had to come back after hours. I paid them for the after hours call over $500, but they are still harassing me for payment on the original service call in which nothing was fixed.

We needed a quote for a repair and a flush on our system. We were told there would be a $199 diagnostic fee/travel charge to come out. They came out I was charged $340 and I don't have a quote, the system flush or system fixed for heat for the house. I have reached out several times and nothing.
