HVAC reviews in Castle Rock, Washington

These are great people that do a great job!!

Great customer service and high quality work.

Lovely people and a great, hard-working team!

From our home to our restaurant they have always done amazing work

Thank you for your great service! Technician and the front office is top notch!

Great experience. The technician was friendly and informative. Will definitely use them again if needed.

First class operation. They were a pleasure to work with. They installed a heat pump and air handler in my house. Union shop

Response and knowledge of what they do is phenomenal. Pleasure doing business with Denali H&AC. Definately will recommend.

They were very professional, respectful, and on time. I love our new system. We are very happy with our choices!

Ryan is the best. He follows in the steps of the original owners trust worthy ness and makes sure that the system is fixed right before he leaves.

Ryan and Kyle were ver professional, worked hard, got the job done early, and great craftsman. Highly recommend

Denali was so easy to work with. Their crew was clean, professional & timely. We highly recommend them!

Excellent company to deal with! Customers come first. Kyle came out this morning and found right away that a salamander shorted out our heat pump unit and he fixed it right away.

They did a very nice job, clean install. Very knowledgeable and professional staff and technicians. They had the new heat pump and air handler installed in a day. Prices were very reasonable. Highly recommend them!

Absolutely love this company! Friendly and hard workers that are detail oriented and work fast! Within a week of contacting them they had the unit installed. They gave us a great bid and didn’t try to sell us something we didn’t need! 100% recommend working with them!

The service man was very polite and extremely knowledgeable and instead of a brand new heat pump, He got my old one alive to fight another day, There are not enough good things I can say about Denali heating & Air Conditioning PLUS they are A Union Shop. So give them plenty of business in the future. A company this good deserves to grow and flourish in our community

My heat pump froze over 2 months after purchasing my home. I called Denali because of the reviews and the simple fact that I like to support my local businesses. Unfortunately, their techs lack of knowledge and experience costed me over $500 and left me with a $400 power bill (emergency heat for 2 months). They sent someone out to diagnose my system and discovered that my defrost board wasn’t working and it was low on refrigerant, the tech stated that it’s not uncommon for older units to have minor leaks and he refilled it and told us that if we replaced the defrost board we’d be back up and running, problem free. He also mentioned our system seemed to be in great shape and it should last us another 5 years or so! I paid the $562 bill and had it replaced based on his “professional” advise. Exactly 2 weeks later, the heat pump turned into a block of ice again. This time when I called, I asked about getting a quote to replace the entire system with hope that they would apply that $562 bill to a new unit. I was told I’d get a call back for a quote, weeks go buy and I had to call them back again because I had no contact from them. They finally came back with a quote and by this time I gathered a few additional quotes. Denali was over $2000 higher then both other estimates! But they said they would apply that $562. This was for the same exact heat pump system. Wow!!! I asked for a refund of this misdiagnosed $562 repair, and they said they would not refund my money. I even offered to eat the cost of parts to make it a little easier on them and they still said no.

Unfortunately, this is just a brief overview. I would recommend anyone that needs Heating and cooling work to get quotes elsewhere and think twice before supporting this business. I’m bummed I have to write these reviews and share my bad experience.

On a positive note, the Lady that answers the phone over there is very polite! But techs that lack experience will lead to money lost and headache.

I called for a service man to come check our unit as the air conditioning was nit working properly. Ryan came out and was beyond thorough to find out the problem, he was very friendly and informative and very appreciative of his hard work. We will definitely use this company again and highly recommend both the company and Ryan. Thank you again..

Called Denali on a record hot week to replace our 20+ year old furnace and heat pump which was failing. Tristan came and gave us an estimate and ordered our replacement quickly. Tristan was a guy. The technicians were very professional and kept their work clean and left no mess behind. Our house is now regulating heat better than we had hoped for.

Denali was a pleasure to work with. From the salesman to the techs I couldn't more pleased.
I choose a 19 seer unit for its size and noise rating. I can no longer hear my outside unit unless I'm standing right next to it. The Installation was very clean and the Technician's were friendly and very knowledgeable.
Excellent local company to work with.

Communication was very good when we called and spoke with Mellissa. There was no pushy sales pitch. McKinley showed up on time and was very pleasant and knowledgeable. He explained things well. Very happy with their service and will use them again for sure.
