Best Preventative Maintenance in Anchorage AK

Just had these guys do an re-install of bathroom fan/duct work. Awesome job! The install was quick, smooth, and in line with quote. The tech went above and beyond and answered my 1 million questions about HVAC / heating systems in general. Friendly and great attention to detail.

Highly recommend them

Diamond Heating is professional, honest, and thorough. Sam reviewed my duct and vent project and found issues another company had totally missed. They saved me a lot of time and money and I’ll choose them for my next project.

Friendly, knowledgeable and helpful.

Without doubt as good as it gets.

My parents (both in their 70s) purchased a new on-demand water heater system 2 years ago for a little over $10,000 from Mountain Mechanical. One year after it was installed it stopped working and took over a week and half for them to get it working. They did not charge because it was within a month of the warranty. But now one year later it stopped working again but this time they were charged over $700 to repair it. I highly suggest people do their research when selecting a business. Seems like they are not installing correctly or the systems are low quality. These systems are supposed to last over ten years so this seems ridiculous. I would definitely not recommend Mountain Mechanical.

They were able to squeeze me in the same day to fix a pin hole leak. They fixed it in about an hour or so. I would definitely call them again

Raul installed my Lennox variable speed furnace and Paul put in an Air Scrubber Advanced-my home now smells like a walk in a misty forest and is as toasty as I need it to be. I have always been impressed with the quality customer service, care, and parts used by Moore Heating. Jason is great and very responsive and always transparent with every estimate. I always recommend Moore heating to my coworkers for their HVAC needs.

Best in town

Only people to answer the phone and come save me when things got messy at 1am.
