"I’m always impressed with the service from Standard Heating. Their technicians are professional, friendly, and genuinely seem to love working for the company — and that pride shows in the care they give their customers. They’re thorough, knowledgeable, and consistently do a great job. Jesse recently came out to test and tune up our furnace, and he was fantastic — just an all-around great guy. Highly recommend Standard Heating and their entire team!"

"FANTASTIC IN ALL REGARDS! Everything from the appointment for estimate, the detail of the bid, the timing and installation of the A/C unit by skilled technicians were better than I expected and much better than their competition."

"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

"Vitaliy and his team were fantastic! The furnace and AC installation was handled with knowledge and professionalism. They were competitive in pricing, no pressure and made the whole experience a breeze. I wouldn't hesitate to recommend them!"

"Our water heater had been leaking. I contacted Dean’s Home Services on Thursday AM 3/5/2026. Their representative Mike Washburn arrived that afternoon. He discussed our options, and we chose a Bradford White water heater. Mike arranged for an install the next day and disconnected the old water heater. At 8:00 AM the next day installers Cody Washburn and Sebastian arrived. The new water heater was installed in an hour and a half. The old heater removed and cleanup completed. We had hot water in less than 24 hours after our original call. Mike, Cory and Sebastian were very helpful and professional. We could not be happier!"

"Do not use this company. Installed grossly incorrect AC system which was completely incompatible and never worked. Chris would not install the correctly compatible equipment and made ridiculous excuses for two years before he finally just stopped returning calls. Made excuses and lied,, as he knew better and is experienced enough to know he made a mistake. His response was to lie, make excuses, and finally just disappear. This cost me $13,500.00 to correct his negligence, so please consider carefully."
