Wow! Great service all around! Darcy was warm and understanding on the phone and did an excellent job with scheduling. John was timely, friendly, and kept working even when it started to storm outside! Diamond Heating & Air has gained a lifelong customer.

received service on our air conditioning unit in July and the fan outside unit was changed & tech releases Freon on accident & had to restore, paid little over $500 for services, a month later when 90 degrees again, air conditioning went out again. They are closed on weekend. Monday unable to get anyone on the phone during listed open hours of business. Also never received promised quote for new ac system. We are unhappy customers, they were referred to us by friend. We will not use them again.

I have and do highly recommend Diamond Hething & Air Conditioning, Inc. My family and friends have been using them for over 25 years. Always dependable, honest, and reliable. Can trust what they say you need and always do excellent work along with protecting your home with drop clothes. Would not use anyone else.

I very highly recommend Diamond Heating & Air Conditioning. Their service, expertise, and timeliness are second to none. We have been using them for a few years now, after my parents have used them for 10+. We have had a furnace repaired, a new furnace installed, and A/C issues resolved. Their prices are extremely reasonable and they are very knowledgeable and always have solved the issue quickly. Give them a call!

If you are looking for a HVAC contractor , I can recommend the Diamond Heating & Air Conditioning. I have been a customer for over 10 years and they are honest, knowledgeable and professional in their service and installation of existing and new HVAC systems. When you schedule an appointment they show up on time and communicate what was done. They are knowledgeable of forced- air systems, as well as boilers.

I was really impressed on how quickly they got my thermostat to work. It turns out something inside my thermostat just needed to be cleaned. So they cleaned it out. They did a very good job. Also the two men that were fitting the problem were very respectful and very kind. I would honestly recommend this company to anyone that have a problem with their thermostat or their AC.

They did a wonderful job installing my new AC unit. They get two thumbs up from me and I tend to be a demanding customer. I’ll be recommending them to my friends and family for HVAC needs.
