Two guys showed…read moreup and said, "Well, we can't work on this because we're plumbers and we won't be able to give you a quote." They took pictures and sent it to the office. They charge me $129 for showing up. 3 days go by with no follow up call with a quote. When I called, there seemed to be confusion around getting me a quote. I was told that the master electrician would call on Monday with my quote. Surprised by that, I asked, "why would an electrician call me when the job had nothing to do with electrical?" I could not get an answer to that. Monday comes and no call. It's now been a few weeks and I've never heard back nor received service for what I paid for. Was my first time calling looking for a new heating and cooling service. Will never call this company again. My mistake was paying the $129 before receiving what I should have received.

My 20-year-old Lennox AC died in the middle of a heat wave on Thursday, 7/2/26. Since it was so old…read moreI reasoned that it would be wiser to just replace it rather than have it fixed. High Ground Service Pros in Milford, NH, aka Sanford Temperature control, did a terrific job in replacing my old Lennox furnace back in March of 2024, so I called them on Friday, 7/3/26 for an estimate appointment. That culminated in their estimator/sales rep Zach arriving, as scheduled, on Monday 7/6/26. Zach proved to be exceptionally knowledgeable & courteous as he evaluated all the variables that would impact the difficulty of installing a new system, and he readily answered all my questions. He provided a very competitive estimate for installing my preferred, high quality Rheem brand system to replace the old Lennox system--an estimate I readily accepted. The installation was scheduled for Friday 7/10/26. That's when the HVAC installation techs Kyle and Jason arrived early to get the job done. They proved to be real pros who completed the job with meticulous precision and attention to detail, leaving me confident that I would not have to take advantage of High Ground Service Pro's remarkable Lifetime Workmanship Guarantee. In summary, I STILL recommend High Ground Service Pros, aka Sanford.

I was a customer of Sanford Temperature Control for many years and the service was great. Recently…read morethey "re-branded" as High Ground. Since then the service has been terrible. Almost a month ago I called just before a heat wave to report that my central AC was not working. They sent a tech the next day. After an hour's work he told me that he could not fix the AC because he did not have the necessary equipment. Huh? They sent a tech to fix the AC and didn't send him with the right equipment to fix an AC? Then he said he would "try to come back tomorrow" with the right equipment. Tomorrow came, and he didn't. So I called High Ground and was told that the appointment had been set up for a full week from that day. How did "tomorrow" turn into the end of next week? Anyway, the heat wave came and went and I did not have AC. A few techs finally showed up at the end of the next week with the equipment they said they needed and worked for an hour. Then they told me they would have to order a part and charged me a deposit of $900.00. The AC still didn't work without that part. Another heat wave came and went with no AC. I called again and asked if the ordered part had come in. I was told that the tech who worked on the AC was on vacation and would not be back until the following week. At that time they would review the account and find out what was going on with the part and the service to install it. What the... Why did he have to be present to find out what was going on with the part? Why didn't High Ground know whether or not the part came in and assign another tech while the first one was on vacation? By the time he returns, I will have gone without AC for over 3 weeks since I first reported the problem. Totally unacceptable. Do not do business with this incompetent outfit. They don't know what they're doing.
