What Our Clients
Say About Us

My furnace went out one day and I called up Northwest and spoke with Shawn the owner. He was able to accommodate me and get a tech out to evaluate what was wrong. The repairs were going to be quite costly so Shawn and I evaluated whether or not it would be advantageous to purchase an entirely new system. With Sean's help and guidance I ended up purchasing an entirely new system air conditioning and heating. Now understanding that the weather is 0° my house has no heating and initially saw Shawn said it would be approximately 5 days before he would be able to get something in. I whined complained begged and finally Sean was able to rearrange his schedule and within the next two days was able to get an entirely new system in an installed. This is not the first system I've purchased from Sean I think I purchased three in total. Each and every time he's been attentive straightforward and extremely helpful. I would highly recommend Sean and northwestern heating for any HVAC questions or problems.

Repair Furnace

Our heater went out and of course it had to be on the coldest week of the year. Their repair team was booked out a few days, but the GM personally stepped in and came to my home within an hour. He ran into a few unexpected complications but never once got frustrated or “mansplained” anything — he walked me through everything clearly and respectfully. He was incredibly patient, kind, and professional the whole time. The pricing was beyond fair, especially for a same-day service call, and the customer service was honestly some of the best I’ve experienced. Highly recommend — truly an amazing company!

Repair HVAC

I can’t say enough good things about this company and the people who work there. When we purchased our first home 23 years ago Northwest Heating and Air had installed the AC and heating system in the house and left their orange contact sticker on the unit. That little sticker and their professional care and maintenance has kept our Tran unit going for well past its normal service term. Northwest H and A recently saved us thousand of dollars. In Dec. of 2025 another company (recommended by our property management company) came to inspect the furnace and said it was damaged and in need of total replacement at the toon of $12000. I contacted Northwest who came out the next day, performed a full inspection and found no problems. They fully contested the competitors claim and said it was possibly a predatory scam and that they unfortunately see this in their industry. If you need honest, old school Idaho people to work with and want to avoid scams try Northwest Heating and Air. I am a fan for life and promise openly to use them on our next install. Thank you again for over 2 decades of service.

A/C System Maintenance

We are very satisfied with Northwest Heating and Air Conditioning. We had a 40-year old heat pump and furnace replaced in early August. They promptly sent a technician to diagnose the problem and managed to work us into their busy schedule within a couple of weeks. The owner, Shaun and technicians, Austin, T.J., and Ryan were efficient, professional and personable. Their dedication and reliabilty got our new system up and running.
