  Testimonial by Ed
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.
  Testimonial by Belisha S.
This is by far the best HVAC company I've encountered in Idaho. They were extremely honest and helpful. Al was great and took excellent care of us!
  Testimonial by Justin Long
I was very impressed. From Robert coming out and actually explaining to me what was going on and what needed to be done to resolve the issue and for actually stating that a technician would need to answer specific questions. Others would have just kept talking. Thank you for being honest with me Robert. For Glen and his crew that came out and spent all day at the house and doing outstanding work with... well everything, Thank you so much. To the owners of Diamond, you should be proud of your people and the hard work they put in.
  Testimonial by Sam Vanderwall
Diamond Heating and Cooling is one of the best, most integrity filled, service businesses I've ever come in contact with. I noticed my heat had stopped coming on at 1 AM. I was freaked out, with a 2 month old baby in my house, I didn't want to go a whole night without heat. I called Diamond, and Chris was at my door by 1:30 AM. Fixed my heat. Now my family is comfortable and safe. Thank you Diamond! I will recommend you every chance I get. You guys rock! And Thank you Chris for being willing to come out tonight and help me. I've used these guys before too and they always treated me fairly and honestly. 5 stars all the way.
  Testimonial by Sheryl Paschal
So very impressed with Diamond. From the first phone call to the service guys out here today. Everything did not go smoothly for Jonah and Dakota. But they did it right and did a beautiful job on the shop heater. I appreciate Jonah cleaning up everything before they left too. What a great team Dakota and Jonah are. Great examples and good PR for the company. You will hear from us again.
  Testimonial by Judy Sutton Harris
We were referred by A-1 plumbing for a water leak in the ceiling. We thought it was a pipe or roof leak, but it was problem from water in a tray under the furnace, Matt was at our home within 30 minutes and had the leak under control very quickly and no more leak. Matt was very professional and friendly and we will be happy to deal with him in the future. We are glad to have a company we can call with confidence.
  Testimonial by Misty Fowers Swanson
Last week our furnace quit working and when we got home (at 9:45 pm), our house was 49 degrees and getting colder. We called Diamond Heating. They had a busy evening ahead with many others in the same situation. The owner was kind enough to take our call and come to our house himself. He had the heater up and working quickly and charged a very low, reasonable rate. Thank you so much! We will definitely be using Diamond again!
  Testimonial by Jim Eisentrager
I can't say enough about the quality service that I received from diamond heating and cooling. Each time they have come, I have received an excellent quality of service. This company knows how to treat their customers right and I highly recommend them. Today Bradley was my technician. Not only was he extremely knowledgeable about what was happening, she was a great conversationalist. He attended to the issue quickly, professionally, and with integrity. Today I signed up for their silver medallion club. A great value that will get me a service on my air-conditioner and my furnace each year.
  Testimonial by Lori Campbell
Second opinion was free. They wanted to come out the same day I called but I actually wasn't ready. They came the next day. Even called to come a little earlier than planned because of a change. Loved it! Ryland took the time to go over what he found and explained everything so that I could understand. Was very clear on repair options going forward. I appreciated it very much! Laura, who took my first call, was extremely helpful and friendly. I will be doing business with this company.
  Testimonial by Diane Riffle
All of the people I have had contact with for this project have been phenomenal! I told Steve before I have any service done, I am going to call Diamond and ask if they have any recommendations. You all went way above my expectations! If you knew me, you would know that means a lot. Thank you for all you have done for me and my family. God Bless You! Service and great people to work with! I will be using Diamond for all my needs!
