Needed to replace it, and Kirk did a great job at a great price. Next, we added a split unit to heat/cool our two upstairs bedrooms. Install was reasonable and it worked well - until it didn't. The business changed owners a few years back, and it's been a struggle to keep the split units working. After some time, Jake came through and fixed our split unit, even adding a surge protector for free. I'm hoping things go smoothly from here. Be aware that surge protection is important on the mountain with all the unplanned outages we face.

We experienced unacceptable and inconsistent communication from Jake of Cantrell's during one of…read morethe coldest weeks of the year (and Christmas holiday week). For the first part of the week, our furnace heat output temperature would not raise above 65°, and after his visit, as tempertaures dropped outside, indoor temperatures dropped as low as 54°. We told him that cold air was blowing in continuously and the furnace would stop all day long. Jake came to our home and told us a specific part was needed and that he would order it. The last update we received--while nighttime temperatures were dropping into the 30s--was simply that the part had been ordered. After that, there was nothing - for over a week and half. Time passed with no updates, no price quote for the part or installation, and no follow-up of any kind. We were left completely in the dark while living in freezing conditions. Two days ago, we finally called emergency service from ACE HVAC. They drove from Hesperia to Crestline at 8pm, diagnosed the issue, ordered the part the next day, and had it installed that next night. Meanwhile, Jake never even texted us back when we asked him what was happening with the part. Our texts were left on read. Cantrell's installed our furnace/HVAC system just four years ago, and as loyal customers, this level of service is unacceptable. For those of us living in the mountains, reliable HVAC service is not a luxury--it is a necessity. We have limited options due to our location, and companies that serve these areas should understand the responsibility that comes with that. Allowing customers--and their pets--to go without heat for over a week during sub-freezing nights shows a complete lack of urgency, accountability, and basic compassion. We were left waiting with no answers, no transparency, and no courtesy during a situation that should have been treated as an emergency.

On Monday, February 2, Mike and Jack came out to install a brand new heater after our old system stopped functioning and was outdated. The installation went well thanks to their professional experience. We had purchased a Nest thermostat but were not aware that we needed to order the Nest charging plate cover and Nest power connector separately. Since we didn't have those items at the time of installation and due to the storm, Jack returned on Monday, March 16 to finish setting everything up. The entire process was smooth and professional from start to finish. My husband and I highly recommend Higher Grounds Heating and Air Conditioning, especially for residents here on the mountain. They are quick, efficient, great value and very professional. We will definitely be recommending them to friends and will use them again in the future if needed.

The repair man showed up on time, and was very clean, friendly, and professional. He asked thorough questions and assess the situation fully. He finds have time us we needed a new heater, but he was very honest. He did a couple of tests to be sure and found that we only needed a new thermostat. He answered all of our questions in detail and in ways that we could understand. He offered to install thermostat for free if we ordered through him. Otherwise, he said it was so very simple to do we can do ourselves, and he even showed us how and sent us detailed explanation on how to do it with one we would go buy ourselves. He offered advice on thermostat types and brands. Definitely will use again!

Old Ownership, Hillman: Extremely disappointed does not begin to describe how I feel after recommending this individual to my recently widowed mother. He got lost, although he lives on the mountain, was routinely rude to my mom on the phone and in person once he arrived. She's trying her best, and address shows correctly with exact accuracy on Google Maps. He spoke very kindly with me and then was very condescending to my mom. Therefore I cancelled him immediately and she broke down in TEARS to me after he left, talking about how he made her feel belittled and reprimanded her that she "needs to learn how to give directions". Maybe he needs to learn how to use Google instead! Maybe he needs a lesson in patience and understanding.... in common decency, respect and basic customer service.

This was my second time using MSP after reading many of their positive reviews and knowing they are…read morea local, small business -- which I always gravitate toward when selecting services. The first time, the technician had placed a sticker on our AC unit, so when cold air stopped flowing this time, it was easy to call them. The process was effortless: customer service answered right away, their system recognized my address from my phone number, and within an hour (on a Sunday evening!) they dispatched two technicians. I also appreciated getting a text notification with their names and photo IDs so I knew exactly who was coming. The diagnosis wasn't the news we wanted to hear -- it was time to replace our 12-year-old AC unit. We had already refurbished the motor last year, which gave us one more season, but it had truly reached the end of its life. What I appreciated most was that we never felt pressured into buying a new unit, even though it was recommended. The technicians walked us through our options: spending over half the cost on a refurbished unit with no warranty or going with a brand-new system that came with one. After thoughtful discussion, both between my husband and me, and with the technicians, we decided to move forward with MSP's recommendation and financed the new unit. The paperwork process was smooth, and they were even able to secure an installation appointment for the very next day. As a thoughtful touch, they even offered us a hotel stay to avoid the heat, though we decided to wait. The next day, two installation crews arrived right on time. One worked in the attic while the other installed the unit outside. Both were courteous, respectful, and professional throughout. The real reason I give MSP five stars, beyond their product and service, is how they handled aftercare -- and the glimpse I got of how well they treat their employees. After installation, my husband noticed the duct bracket hadn't been done exactly as he'd requested. Since we have a Belgian Malinois who chews on everything, he wanted the cables covered with a custom metal bracket, which had been discussed with the technician. Clearly, there was a miscommunication. I called the next day and spoke with Bella (the manager, I believe). She explained that this was technically outside their scope, but she listened carefully, acknowledged the issue, and immediately sent her crew back the same day to resolve it. I appreciated that she didn't get defensive, but instead valued our input and honored our trust. Finally, I want to applaud MSP for the way they treat their employees. All four team members who helped us mentioned how much they enjoy working there, and it shows in the quality of their work. On top of that, we were thrilled to learn that the X Series unit we purchased is the kind of product that could be sold at a much higher rate through a corporate AC company (according to one technician who used to work at a corporate), but MSP offered it at a fair and reasonable price. That kind of transparency and value is rare. I truly believe happy employees and fair business practices translate into happy customers, and this company is proof of that. I wish them continued prosperity.
