"Under no circumstances would I recommend John Henry’s. The fact that they have such glowing reviews makes me genuinely question whether they’re legitimate or incentivized internally, because my experience was the complete opposite. Nearly three weeks ago, I scheduled a duct cleaning and annual HVAC maintenance. On a Saturday, I received a call informing me they were “too busy” to keep my Monday appointment and wanted to push me out another two weeks. I told them that was unacceptable due to the heavy construction in my home and that I would need to look elsewhere. Suddenly, they were able to fit me in on Tuesday and offered a $50 credit. Tuesday arrives, and the problems start immediately. Two technicians showed up and left black marks on about 15 of my stairs. They initially denied it but eventually wiped them down with a cloth and water. Later, I discovered they somehow got paint inside one of my electrical outlets from dragging their cord across it. I spoke with the manager, who showed no concern or accountability for the damage. I was also informed—after they arrived—that they couldn’t complete my annual maintenance because neither technician was mechanically trained. So once again, I had to reschedule, and someone else came out the next day. The technician on Wednesday was by far the worst part of this entire experience. He was rude, dismissive, and clearly more focused on selling memberships than actually providing service. When I mentioned the $50 credit I had been promised, he looked at me like I was making it up. As he tried to upsell me on their membership, I asked if they could credit the duct cleaning since it’s included in that plan. Despite me telling him they had cleaned my ducts less than 24 hours earlier, he called the office claiming it happened the prior week. While on the phone, I could hear him questioning whether I even deserved the $50 credit I had been explicitly promised. When I asked if the 15% part discount (which is included with the membership I would be paying for monthly over a two-year lock-in) would apply, he acted as if I was asking for something unreasonable and told me I was “getting too many discounts.” None of these were random discounts—they were things they advertised. At this point his behavior confirmed my suspicion that this company prioritizes sales tactics and profit over honesty or customer service. I declined the membership. Once he finalized the bill, it was more than $150 higher than the quote I received the day before. Since then, I’ve called the office three separate times asking for a simple cost breakdown: the technician’s cleaning charges and the UV bulb replacement. The manager still cannot provide this and continues speaking in circles without answering my direct question. Bottom line: Do not hire this company under any circumstances. There are many HVAC, electrical, and plumbing companies that value their customers, communicate honestly, and provide professional service. John Henry’s is not one of them."

"Excellent. They called me immediately. Work performed quickly. Did a professional job and were very reasonable. Would highly recommend."

"Beware. They charged me double shipping even after I told them I would wait so I wouldn’t have to pay two shipping fees. The last item was a fuel pump that I had a problem with. I have made 4 calls to ask for help with no return call. Poor"

"Please pass on my kind words so someone up the line knows you have a great employee in Chris. He took time to come out today and install a new battery and set everything up for me. I am once again up and running. Chris arrived early, was neat in appearance, polite and very efficient. He did a great job and I appreciate the timely manner in which I was treated. In all of my dealings with Sentry Electric I have been more than happy and recommend them to others seeking generators or electrical work."
