EXCELLENTBased on 22 reviewsLauren GallantFebruary 24, 2023I was referred to this company by another HVAC company because Maximum H&C *specializes* in boilers. My home's boiler system had an issue that I tried to get addressed via our home warranty company, but was unsuccessful for several weeks leading to no heat in the entire home for way too long. Jim and Dallas addressed the issues immediately, coming out to our home the next morning to inspect the issue and then returning the very next day to finish the job. Not only did they address the issues to fix the heating system fully within 2 business days, they were informative throughout the entire process explaining the exact problems with the system. We even were presented with several different options to fix the system, with varying cost estimates. Now that it's fixed, we are back to being comfortable in our home! A HUGE, huge thank you to this company. We appreciate your hard work!Daniel FischerMay 31, 2022We have had multiple issues with our AC units and Dallas and the crew have been able to get out to us in a very quick manner. One time on a Sunday morning! Him and his staff are very professional and take care of us like we are family!Melissa MoldovanJune 22, 2021I am impressed!!
