We took advantage of the free design services for a heat pump heating system offered by QuitCarbon. After completing their home assessment questionnaire they gave us sizing, pricing and rebate information. QC referred us to Harry Clark Heating and Air Conditioning for a complete upgrade to replace our gas furnace. HC owner Don Marshall spent an hour and a half assessing the existing heating system in our 1908 home, answering all our questions and providing a detailed quote for a two zone system the next day.After reviewing the quote with QuitCarbon, we decided the price was competitive and chose not to get other bids. I should mention that I’m a licensed mechanical engineer and have lots of experience working with contractors. Armando Hernandez and his crew completed the install in one week and we were up and running on day 5. The quality of the workmanship was excellent. Armando addressed my many questions and was a pleasure to work with. There was an issue with a defective part in the air handler. The project manager Matt Schwoyer was able to resolve it with their supplier, and the part was replaced the following week.Everyone at Harry Clark was professional and responsive throughout the whole project. We are pleasantly surprised with the improved and consistent comfort level in our home and would recommend HC to anyone considering a heat pump retrofit.
Harry Clark did an excellent job of replacing my aging gas furnace with a hybrid heat pump. They also provided me with zoning which I didn't have before. Everything is working great and they did a good job.
certain things like paying taxes, root canals and colonoscopies come with being a grown up. every adult has had to replace a furnace or air conditioning system. last week my heat wouldn’t come on and a repairman came out to fix it. he told me the unit needs to be replaced to the tune of $6,500. being a trusting individual, as i lowered my trousers so they could shove the hoses up my butt, i called Harry Clark for a second opinion. Harry agreed the furnace is old and will eventually need to be replaced but the reason it wasn’t working is the thermostat. he changed the filter and replaced the thermostat. thanks to Harry Clark, i feel like a kid again.
Harry Clark is the best. I always call them for the checkup on my furnace (which they installed), and any plumbing problem. Reliable, honest, and expert. Never any kind of problem with their service.
Had a need for Harry Clark Plumbing to snake a drain and the tech got through the crapola perfectly. I’ve always had pleasant experiences with Harry Clark, both plumbing and heating. As a property mgr and broker I recommend HC.
