Thank you Heinmiller! We had the best experience during our routine maintenance checkup and service today. You sent professional, Phil Jackson, to be our technician and he is doing the Heinmiller name right. He is a wonderful representative of your company , its quality and the level of service you are known to provide to your customers. He was timely, courteous, knowledgeable, hard working and an absolute joy to do business with. Thank you to Phil and the entire Heinmiller family of representatives. We appreciate you so much.

We've been using Heinmiller for 30 years. They have always been trustworthy and dependable. Our previous unit that they installed lasted over 25 years, and it finally gave out this week. Heinmiller gave us a very fair quote on a new unit, and even provided an option to repair our old unit. We decided to go with a new system that they installed it a day after we accepted the quote. Sean, Joe, and Ken were all very professional and courteous and did a fantastic job. There was great communication throughout the estimate process and installation. We are now enjoying cool AC once again.

They took care of our AC needs quickly and at a reasonable price. The service techs were on time and worked proficiently. Patrick Liner spoke frankly and honestly with me about our needs and didn't oversell me. I appreciated that. Our new air conditioner works great and I think this is a company I can count on to deliver quality.

We have trusted our home AC/heating system to Heinmiller Heating & Cooling for at least 25 years now. We take advantage of the maintenance agreement service as well. They are responsive and professional.

I would rate Heinmiller much higher than a 5 if possible. My self and family have been using their services since the day they opened their doors and have always been 100% satisfied. It’s starts with the wonderful lady scheduling your appointment and always finding a way to make it happen even if you have an urgent last minute need. Their prices are reasonable. ALL of their technicians are extremely kind and knowledgeable and always eager to teach when asked a million questions. I’d like to thank eac and everyone of you for ALL you do!
