"Andy was very helpful and thorough. Our A/C went out and it was a hot day so he arranged his schedule to come right out and fix it that day for a very competitive price. We would definitely use them again."

"I called Andy at 5:30pm after noticing my furnace was blowing cold air during a snow storm... Not only did Andy come out immediately to assess and fix the problem, he came back at 9:30pm the same night when the furnace needed a minor tweak. He only charged me $49 was super nice and talked me through the process so I can trouble shoot it in the future. The Avalanche service was exceptional and affordable."

"I bought a new home and when the inspector came back he found my air conditioning unit was installed incorrectly. I was referred to Andy and Avalanche through a coworker of mine, he was prompt and professional and fixed the incorrect install and it passed the re-inspection with flying colors! I plan to use him in the future and I recommend him to everyone!"
