Communication was good, I got a text reminder and an email for my appointment. The technician texted when he was on his way and arrived with a partner to do the service. They found my blower capacitor was running at about half power and replaced it for a fee after having me approve it. They are straightforward, respectful, and clean. No complaints at all about the techs or their work. All in, these guys are great overall. Their techs are great, the communication is great, and the heat runs like new. I will be going back to them time and again.

Due to an unforeseen and unexpected family emergency, I discovered upon arriving at my family member's home that the furnace was not working. To make matters worse, we were experiencing extremely frigid temperatures. The team at Keystone arrived with ceramic Room heaters for me to use while I coordinated my personal situation. Within a short time, Dave Katt personally called me to offer financing suggestions to assist me in my ability to repair the furnace. He and his company have been beyond a blessing to me and my family. I would go above and beyond to highly recommend Keystone for any of your heating or air-conditioning needs.

I'll post some screenshots of our conversation today. They were rude and they were talking down to me. One instance... They asked me if I changed the batteries. I told them three times but the next thing I know they responded again that "It's not hard to change a battery". No one should have to deal with any type of hostile communication from these people.

The HVAC company that Costco uses attempted to sell another carrier that was not part of Costco's agreement with their vendor. So I took the gamble and interviewed Junior. As soon as he said DAIKIN, he was in! A close realtor friend in Scottsdale AZ did extensive research on mini-splits and told me IF you could find a dealer who carries DAIKIN (super quiet system), choose them! My job was done within a few days of meeting Junior. A 2 day install with perfect detailing, professional, on time, etc., etc. And their price was so reasonable. Am I HAPPY, you betcha.

On January 25, 2026, I experienced frozen pipes and contacted this company. To their credit, a…read moreplumber arrived within two hours and spent about two hours thawing the pipes, which I appreciated. I had shut off the main water line before leaving town for a few days, and upon returning, I followed their instructions to turn the water back on. Unfortunately, I then lost water pressure in both the kitchen and bathroom. I called to report the issue, and while they did send technicians back out, the process became frustrating. It ultimately took six visits over a period of time to diagnose and fix the problem, which turned out to be a simple cartridge issue. In my opinion, this should have been identified much earlier--likely during the first return visit. The total cost came to $866.00. On the final visit, I was asked to pay an additional $136.00 to replace a $23.00 cartridge, a repair that would have taken only a few minutes. I declined that charge. This last visit took place on March 30, 2026. Communication was also lacking, as some calls were not returned. While they did send someone out twice at no charge, no real progress was made during those visits. I have used this company for 16 years and had always been satisfied in the past, which makes this experience especially disappointing. Unfortunately, due to the high cost, inefficiency, and lack of customer care, I will not be using them again.
