Diamond Heating/AirTemp Alaska Customer Reviews

At Diamond Heating, we believe that the true yardstick by which to measure our success is not profitability or industry awards, but your satisfaction. Simply put, nothing makes us more proud than hearing from our customers about how happy they are with their heating or air conditioning service. Here’s what some of them have had to share…

Guys. GUYS. Check out this month’s savings from my upgrade to new energy efficient heating systems- a furnace and on-demand tankless hot water heater. I honestly can’t believe the difference, plus this winter has been a lot colder than the previous year!


I was having difficulty installing a new Nest thermostat because my heating system only used two wires and I needed a “common” to power the Nest. I contacted Jack at Diamond Heating and he was very accommodating and scheduled a technician named Robby to come out first thing in the morning. The next morning Robby called to ask if he could arrive 10 minutes early for our 8:00 scheduled appointment. That is so refreshing when people show up on time. I was very impressed. Robbie was extremely knowledgeable and very polite. He reviewed the issue with me, discussed his game plan and had the new thermostat correctly powered in less than an hour. I give Diamond Heating FIVE STARS and will be sure to use them when I have a heating issue and I will be sure to recommend the company to all of my friends!


I called six (6) local Anchorage Plumbing and Heating companies today (1 Nov 2018). I needed a quick simple estimate to replace a hydronic garage heater in a two car garage. Diamond was the only company that found time in the day to send some one to my house. Out of the other five companies I called, one company scheduled me for tomorrow (2 Nov), another one for 28 Nov, and the rest neither took calls or returned calls. The gentleman called prior to stopping by to let me know he was in route. He checked out the current hydronic heater setup, asked questions, and quickly determined that I didn’t need a replacement. He troubleshot the existing set-up and saved me a ton of money. His honesty, integrity, and personality tell the story of just were Diamond Heating is currently and where they will be in the future. Any company would be lucky to have individuals as outstanding as this gentlemen. It’s rare when you find that kind of quality in an individual and in a company, especially today. Diamond Heating just found a new customer. Thank you!

This is my first time using Diamond. I received quotes from three heating suppliers for a new furnace and hot water heater. I chose Diamond and am glad I did. From the quote to the install to the follow-up, everything was timely, knowledgeable, and courteous. This is a very welcome surprise about a heating and plumbing company. Diamond’s products and services are reasonably priced. Don’t compare on price alone, because in this field you get what you pay for.

I recently needed repairs on my furnace. The service I received from the technicians up to and including the management was fantastic. Having a older heating system presented some unique challenges. Diamond was up to the task and provided great diagnostic skills with fair pricing. Special thanks to Tom and Jerry!

We finally decided to upgrade our 20 year old furnace with a Trane model that’s super efficient and operates at very low noise levels. Hats off to Joe and crew for exceptional pricing and workmanship, this was not an easy job as we added a new heating zone, air scrubbers, and WiFi operations. I would rate Diamond Heating as the best in Alaska!

Last month (July 2018) Diamond installed a new IBC boiler and passive hot water tank in our 37-year-old house on the Lower Hillside. The salesman, Joe Dudley, was friendly, extremely well-informed, and helpful after the installation in patiently teaching me the ins and outs of the new system.

The installation was extremely professional and superbly neat — almost a work of art! Kudos to Robby V. and his helper, Keith.

The telephone staff is very friendly and helpful as well.

And here’s something special: last Sunday, during a windstorm spawned by a waning Pacific typhoon, we had a brief power outage, most likely with a surge. The boiler shut down and could not be restarted. I called Diamond, the answering service picked up on the second ring, and within 10 minutes I got a call from Keith (the technician). I described the problem, he thought for a moment, then said he would be right over. 30 minutes later, he arrived and fixed the problem. That is exemplary service for normal business hours on a weekday — and this was a Sunday.

In Alaska, a heating system is the heart of the house — the most important “appliance.” I feel that we are in good hands with Diamond.

True Alaskan service !! Tom was exceptionally professional. Then I met Keith and don’t let me forget Cara. What a great team. Trust is the first ingredient in customer service. I will call them again and refer them always. Timely, thorough and kind. Thank you

Excellent company, excellent customer service. Got our furnace back up and running very quickly and performed some preventative maintenance at the same time. Would highly recommend to anyone.

Brian Harten

I just wanted to say thank you so much for the awesome service! I called at 7:45am because our heat was out and by 11:30am, it was fixed and we are warm again! I appreciate the fast response and I will definitely recommend you to others.

Had a great experience dealing with Joe and Herman. Both were very professional Joe had all the tools to give me a estimate for a new furnace along with various options etc. and was able to print it out on site. Herman showed up and installed the new furnace with all the options that I wanted. Herman had all the tools and knowledge and skill to get the job completed in one day. Diamond Heating also had a three year no interest program that I was able to take advantage of. I want to thank Diamond Heating for taking such good care of me.

I personally know the contractor as a good person and a good businessman!

Dave Harper

I have already recommended Diamond Heating to a friend. They did a great job!

In 2009, your company installed a 95% efficient new gas furnace and on-demand gas water heater at our residence. Your technicians did an excellent, prompt and professional installation. The system continues to work perfectly with no problems. I wanted to personally thank you for the great choice in selecting these units for us and the excellent and conscientious work done by the technicians.

I thought you might be interested to know how much energy and cost savings we have realized since the installation. I keep yearly energy records for our house. For 8 years prior to the install we used an average of 8904 kwH of electricity and 1773 cu ft of gas. In 2010, we only used 7835 kwH of electricity, and 1217 cu ft of gas. At our last year’s rate of $.89/ kwH and $.135 per cu ft of gas, we saved $144.32 on electricity, and $494.84 on gas last year ($639.16 total). As you can see we are totally happy with our new system and continue to refer our friends to your company. Thank you very much!

John Sarvis

Great service & fast & clean as always!

Komi & Michelle Om

Our contractor was excellent. He took time to show us how to operate everything as well as maintain filters and take care of our investment. I was pleased with his promptness and his knowledge.

Nate Anderson

Diamond Heating was recommended by two different people – I was not disappointed in their work or their product.

Steve Skrocki

Craig Chenery’s (Comfort Consultant) knowledge & professionalism led us to go with Trane & Diamond Heating. Despite 2 other bids, one of which was lower, for a new furnace. We went back to Diamond Heating, because of Craig, to purchase and have installed two Panasonic Fan/Light units a year after our furnace purchase. We give Craig our highest recommendation.
