General Info
Beginning in 1995 with only three employees and one truck, Diamond Heating quickly grew into the largest new construction installer of residential heating systems in Alaska! In 2005, after just 10 short years in business, Diamond Heating was honored with the prestigious “Subcontractor of the Year” award from the Anchorage Home Builders Association. In 1992, AirTemp Alaska opened its doors providing Heating and Air Conditioning Maintenance, Service and Repairs for Commercial Buildings throughout Anchorage and the Valley. Both of these companies built remarkable reputations for reliability and exceptional service with each of their respective customer bases. Then, in 2006 Diamond Heating joined forces with AirTemp Alaska, creating a versatile company with capabilities to handle any Service, Replacement or New Construction phase of the HVAC industry. Today, our specialized planners and designers enjoy working with both Residential and Commercial owners and builders to create optimal heating and ventilation systems to perfectly balance with Alaska’s extreme temperature swings. Our Commercial Replacement Pro’s specialize in changing out old Roof Top Units on ANY size building, with minimal down-time! We can orchestrate major HVAC renovations and handle all the details from Engineering to Electrical and even Roofing. Our talented Installers and skilled Technicians regularly work all over the State from Dutch Harbor to Prudhoe Bay, providing full service for all Heating and Air Conditioning systems, to all Alaskans!

I asked for multiple contractors to come and provide an estimate for the repair of my boiler. All of them showed up and did just that, until I got to Diamond Heating. The tech spent 15 minutes just looking at my unit then went to the vehicle for about 30 minutes to "write up his report", and when he came back, asked for an $89 service fee. When I scheduled the estimate on the phone, not once was a fee mentioned. I didn’t think anything of it, because the other 3 contractors said they provided a free estimate. Diamond only said they would send out a tech, but did not say that would be associated with a fee. I figured there had to have been some kind of mistake so I called the secretary that set up the appointment to clear things up.

On the phone she apologized for not disclosing the fee. She then said an owner would call me.

The owner called me shortly after the tech left, and I tried to reason with him and ask him if he would not feel wronged if someone came to his home to just look at a system and then slapped an unexpected fee in his face. He cut me off and then insulted my intelligence by saying "$89 dollars doesn't even begin to pay for the expenses associated with what his tech just provided me". They are now demanding that I pay a $89 fee and have promised to send it to collections. But prior to showing up to my home they did not say an estimate came with a fee. They also never provided an estimated for the repair or replacement cost. The tech simply said it is broken and that a sales rep would be calling me to schedule an estimate appointment.

I never felt so taken advantage of and bullied by a contractor before. How could a contractor not tell you they will charge you $89 for 15 minutes of looking at your unit and then expect to bully you into paying

Way to expensive, poor customer service (had to repeatedly call to get a quote). In addition to the salesperson was very rude when i inquired about purchasing a furnace and then doing a self install. Took my business elsewhere.
