Positive: Professionalism, Quality, Value We received multiple quotes for HVAC replacement from local companies and Heritage gave the best price and product. Trent was very kind and knowledgeable during our assessment. Larry and his assistant were kind, knowledgeable, and overall wonderful during the install. We had our old units replaced and the difference we felt was immediate and wish we had done this sooner. If you are debating on whether or not to replace an old system, take the plunge and give Heritage a call.

Positive: Professionalism, Punctuality, Quality, Responsiveness Of all of the places I called Heritage Heating and Cooling responded first. I was told a technician would come the next day between 9-10 am. I promptly got a text that my tech was on the way that morning and he was there by 9:05. Ben was my tech and he was pleasant and professional. He discussed everything that he was checking and I didn't feel like I was being taken advantage of since I don't know much about AC things. He figured out the problem quickly, fixed it, and I am considering getting a maintenance package with them in the spring because of the great service I received that day. I will recommend them to others and will call them for any future needs.

Had Heritage come out back in October for a quote after receiving a quote from another company. Heritage was able to install a better system with a better warranty for a way better price. Ben was very thorough and friendly. Had them back out tonight for an emergency call because the new system was struggling in the frigid temps. Turns out it was just an air filter needing changed. We felt awful Ben had to get out in all the snow, but he was happy to help and didn’t make us feel bad about it at all. I would recommend this company to anyone. Seriously, ditch the other company and call Heritage!

EXCELLENT SAME DAY SERVICE! Of course, when the first three 85°+ days came in May, our A/C was not "blowing cold". I called Heritage H/C was listed as 24/7 service. 1 hour before our scheduled service call, I received a text message with a clear photo and short personal bio of the technician who would soon visit our home. The friendly/polite technician arrived early and asked if I needed him to wear a mask, no need, I'll keep a 6ft distance. He first explained what needed to be fixed, offered several solution options and had our house cooling within 15 min of his arrival. I love the overall professionalism of this company and highly recommend.

Positive: Professionalism, Quality, Responsiveness Patty and the team at Heritage never disappoint on providing excellent customer service and fast response times. I’ve used this company for 4+ years and there’s never been a time I felt I was overcharged. I’m most impressed with the service reminder text which includes a picture of the technician and a brief bio. In today’s world, it’s always comforting having a face and name of whom to expect. I can’t sing this companies praises enough! Good, honest, hardworking people are hard to come by and they’ve definitely proved themselves.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value I called Heritage on the recommendation of a former employee. The tech, Ben, did a thorough examination and went through all the issues that had built up since the original owner installed the system. After determining the cost to fix all the issues was growing rapidly, he took the time to explain all the install options and gave me some estimates based on our existing system and house layout. The estimate was quite a bit lower than other systems I later priced out. After deciding to use Heritage for the new system, they scheduled the install within a week. Zach, Tyler, and Larry were able to install the new furnace, AC, and outdoor units within 4 hours and had everything up and running. They tore down the old equipment and installed the new and left no trace they were there. They answered all my questions and made sure I completely understood all the work they had done. I would fully recommend this company to any family and friends.
