Always arrive on time, professional, courteous, friendly, honest and reasonable rates. After leaving a competing company and coming to Diamond, I couldn’t be happier. Will highly recommend to others!

After having a hard time with a series of event that had already happened I was very stressed and very upset then my furnace went out on top of everything. I called Diamond heating and cooling and they had one of there techs out to my house that evening to fix the problem. The tech was extremely friendly and informative. I was so thankful to have called them. My mind was put at ease and they took a lot of stress out of the whole situation. The savings plan they have is amazing as well. I will be recommending it to everyone :)

Working with Diamond was great from start to finish. Our sales person listened and was really helpful guiding the selection. We solicited six bids for our new system. Diamond was one of only two companies that actually did the math to assure our system is sized correctly. The install team was fantastic. We made the right choice with Diamond Heating and Cooling. Many thanks.

Easy to work with and knowledgeable. We installed a ductless AC unit. Diamond gave a fair price for product and labor and worked with us on the desired placement of not only the inside unit but all the pipes too. Everyone was very friendly and did a great job. Will definitely use them again for future work.

My Name is Laura Samuelson. Our family of seven has lived the adventure of having six asthmatics in the home. Our five children and I have all experienced many years of inhalers, nebulizer treatments, steroids and hospital stays due to asthma attacks. The high cost of medication, doc-tor visits, E.R. trips and “Camp-outs” at St. Lukes and St. Al’s took quite a toll on us. Financially it was a strain, and emotionally it was difficult to watch each other struggle for air, sometimes to the point of turning blue.

In 2011, we skeptically allowed Diamond Heating and Cooling to install a Micro Power Guard into our air system. I expected nothing to come of it. In fact, I wasn’t thrilled about a ninety-nine dollar charge per year for filters since we were already stretched for groceries and prescriptions. I am thrilled to report that the change has been amazing! There is much less dust in the house when we run our system. Our air circulation creates a marked difference in our quality of life. There are less asthma triggers floating about our home causing a huge decrease in asthma attacks. I am so very pleased to say, that for the first time ever, most of our inhalers and nebulizer medications have actually expired! We have not had a single E.R. visit, or hospital stay due to asthma since the installation of our Micro Power Guard system.

We began noticing that on days when we didn’t run our air conditioning or heater, the family started to cough again and have trouble breathing. About the time the inhalers start to come out of hiding, one of us will get a clue and the system is turned back on. Within hours, the coughing stops.

This has made such a difference in our lives that I wanted to share the in-formation with anyone else who struggles with illness due to air quality. The Micro Power Guard filters have been for us, a powerful tool in saving thousands on medical expenses, creating cleaner air in our home and keeping us noticeably healthier.

The Furnace at our rental unit finally had enough. Shortly after contacting Diamond Heating they diagnosed the old furnace. Was very nice that the technician actually brought me over to the unit and showed me exactly what the issue was and how it failed. They came back the next day and installed the new unit and were very respectful to the tennants. Thanks guys!

All staff we have had contact with have been friendly and knowledgeable. We have been treated like friends, not just customers. We would most definitely recommend Diamond to friends and family.

The final price was very “fair”, meaning it was in line with competitive bids. The quality and expertise was exceptional. We are very happy. There is a personal touch to your company. We feel like we made new friends! Obviously, it’s never “fun” to have to replace expensive items, but it’s a necessity for most homeowners. Your friendliness plus knowledge really helped us go through the ordeal!!!”

John was on time, and explained everything necessary to do with no pressure to do it. Their office called immediately and came the same day. We were impressed with their up-front and clear pricing.”

I usually compare several companies before I make the final decision, reading the customer reviews on this particular company was most impressive & perhaps was the deciding factor. The repairmen were prompt and called ahead if there were delays. They were most courteous and could clearly explain the problems. Pricing was very fair. They were quick and competent with the repairs and when questions arose, they addressed them immediately. Customer service reps were equally of high quality. I have seldom run into a company of such high integrity.

Just wanted to let you know again that I am extremely satisfied with the work performed yesterday by Diamond Heating & Air. What I especially appreciate is the fact that the problem was treated correctly and the fee was most reasonable. Your tech, John, is very thorough and honest guy. That’s refreshing, believe me. You’re lucky to have him. Based on my positive experience I’m sure we’ll do business again. Thanks much.
