Save Money with a New Heat Pump

Installing a heat pump, also known as a mini-split, is a great way to keep yourself not only warm in the winter, but also cool in the summer. Despite the name, heat pumps serve not only as heating units, but also as air conditioners. They can also be a cost-saving investment. For a limited time, rebates are available to make the unit even more cost-efficient. Most installs pay for themselves in as little as 4-5 years! Read more about heat pumps here

Andy with Avalanche is amazing! He did an awesome job on a furnace tune up for one of the rentals I manage. Even more, he alerted me of a very small pinhole leak in a nearby drain pipe that he noticed during the tune up. He saved my owners potentially $1000’s because after getting the pipe repaired, it was clear it was close to bursting and would have flooded the basement. If you want someone who will do a great job and goes above and beyond in caring for his clients, call Andy with Avalanche!

Received prompt service on the phone from Andy and had a technician out to repair the problem in short time. The technician Jacob showed thorough knowledge of diagnosing the problem and quickly came up with a solution. Highly recommend their service.

Fantastic service! Jacob came in, diagnosed the issue within ten minutes after my description, was honest about the part and timing of getting it in and still got it done faster than I expected. Pricing was good too! If you like to have companies in your book that you will depend on and trust, I'd add Avalanche for sure. Thanks again!

The company went above and beyond in delivering quality service in an efficient and proficient manner. They were easy to work with, communicated promptly and fully completed the project as agreed upon when they provided the estimate (no changes in the final bill). We were very pleased with the service and with the new water heater, furnace and HVAC.

Great local company. They’re always right on time, professional & explain everything really well. 👍. They’re great about making every attempt to get out to you as quickly as possible, I called this morning and they were out to service our commercial HVAC systems that afternoon! We’ve used them for years and like that we can continue to do business with a quality local business. Thank you!
