Report
We had several different issues going on at our rental unit and called several other contractors to come out and help us fix our water tank and heat issues. Every other contractor failed and left our home without a working heating system. When we reached out to Hillestad's they diagnosed the problem right away and sent a team back the next morning to get both our heat and water tank back up and working properly. I'll never call another HVAC service again. I highly recommend them.

We worked with Dan to give us a quote for a split system to be installed in our cabin. We received a quote within a week and were able to schedule an install shortly afterwards. Crew that came to install was professional and quick. We also reached out to Dan after install to get a few questions answered, which he was quick to respond to. I wish all contractors were this professional and responsive. We will be returning to Hillestad for our future business.

Very friendly, prompt, and knowledgeable. Trustworthy to where for my specific situation it would be cheaper to use a different company, and they told me that. That's the type of company I want to do business with! Will definitely use them for future needs. Above and beyond my expectations.
