"It was our third time using The Handy Veteran and it will not be the last. Kevin and his team are absolutely top notch! Our first job with Kevin was to replace and paint all of the wood and trim in our entire house, replace carpet with LVP flooring on a third of the floors in our 3000sqf home, refaced our fireplace, install a new front door, & paint the entire house. Second job was to repair and paint our large deck. This last job was to replace more floors, remodel our guest bathroom and hang multiple lights fixtures. Our first job was in 2020 and the initial work they did is still perfect. Kevin stands by his work. He is not satisfied until the job is done right and was extremely accommodating to all of our requests. He wanted us satisfied and happy with the work and even made some great suggestions that really enhanced the final outcome. Him and his team are extremely respectful of our time, professional, friendly and trustworthy. Also very fair with their pricing! "

"Great to work with. They were efficient and knowledgeable. They took care of the rebate for our heat pump. Only thing lacking was responsiveness to email/phone communication after the install was done. Heat pump system is working great."

"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."
