My heating unit was having problems with its ignition cycle and had stumped a previous vendor, who suggested replacing the entire control board. Kevin from Stable Temp very quickly diagnosed the problem as a bad flame sensor. He replaced it and within 20 minutes the problem was solved. He was professional, friendly, and extremely competent. I recommend him and Stable Temp without reservation!
I'm a real estate agent and property owner/ landlord. I'm busy, often have urgent HVAC needs and price-sensitive clients. I really appreciate how responsive Ivan is when I need to reach him. He's also very honest, which is hard to find. He's good with my clients as well, which is paramount to me because that affects my business and my reputation. Quality of work is great and pricing is very competitive, especially when they show up on time and do what they say they're going to do. Over the years, I've been through countless HVAC contractors and Stable Temp is the best I've found.
My assigned technician, Kevin, was outstanding! He delivered a thorough assessment of the problem with my split level, used language that was easy to follow and understand, and was professional from the beginning to the end. I am beyond satisfied with my personal experience. Thank you for this positive experience, Stable Temp!
UPDATE: I am writing to update my experience with Stable Temp. I initially called them to fix an issue with my property's HVAC unit. Their technician diagnosed the problem as a failing control board and gas valve, which would have been a costly repair. However, the problem continued after their visit. I was forced to call another company to get a proper diagnosis. The second company was professional and quickly discovered that the expensive parts were fine. The real issue was simply an incorrect setting on the unit, which he believed was improperly adjusted during Stable Temp's visit. He corrected the setting, and the system has worked perfectly since. He also confirmed that the air filter was destroyed by the previous technician. I'm frustrated by the complete misdiagnosis from Stable Temp, which caused unnecessary stress and could have led to hundreds of dollars in needless repairs. — The initial scheduling with Stable Temp was easy, and the technician, Kevin, was professional. I hired them for a routine $169 maintenance check on a relatively new furnace (installed 2021/2022). However, the visit concluded with a major red flag: a recommendation to replace both the gas valve and the control board for a total of $634.98. This was highly suspicious for two reasons. First, it is extremely rare for both of these major components to fail simultaneously on such a new system. A proper diagnosis should isolate the single point of failure. Second, and more importantly, the initial estimate made no mention of the manufacturer's parts warranty, which is almost certainly still active on a system this new. The recommendation to replace everything at full cost, without proactively checking the warranty, felt like a clear attempt to use a low-cost maintenance call to generate a large, unnecessary repair bill. I declined the repair and informed the company I would be getting a second opinion. *** UPDATE: Manager's Response Confirms Suspicions *** After I expressed my concerns, the manager (Vlad) responded to me in writing. His email confirmed my decision was correct. He admitted that their diagnostic process is not always definitive, stating it is sometimes necessary to "replace one [part] to see how it affects the rest of the unit's performance." This is essentially a "guess and check" approach to repairs, where the customer pays for the parts being tested. He also confirmed that the warranty was only checked after I questioned the initial estimate, which should have been the first step. This experience has shown that their process can lead to recommendations for expensive, non-definitive repairs that may ignore a homeowner's warranty coverage. I paid the $169 diagnostic fee to close out this engagement and am proceeding with a different company. I strongly advise other homeowners to be cautious.
Kevin was great. Gave me all the help I needed to make sure my A/C unit runs properly for the foreseeable future. Highly recommend him and stable temp for any job!
