Save Money with a New Mini-Split

Installing a ductless mini-split is a great way to keep yourself cool in the summer and also warm in the winter. Mini-Splits, also known as heat pumps, bring in the air from outside and cool or warm it using the electricity already running through your home with less energy than a full heating or cooling system. 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

After our warranty company sent out a competitor and told us we'd be looking at a $600+ bill for cleaning our coil and blower to get our AC working again, we decided to get a second opinion with Avalanche and we couldn't be happier. Andy gave a courtesy call, arrived up on time with a friendly smile, and explained what he found in layman's terms. His honesty and expertise saved us that $600 when he discovered the previous company neglected to remove a piece of fallen insulation that covered the coils and was causing the AC to freeze over. You just don't find people as genuine, well-meaning, and with such integrity like Andy at Avalanche anymore and we are eternally grateful for his time and expertise. He has a customer in us for life now, when we aren't so fortunate with our hvac outcomes. Thank you Andy for saving the day!

Jacob was very professional and courteous when he came to my home to fix the AC unit. He was able to explain the issue with the unit very clearly, and spent time showing me how to operate and set up my Nest unit. Overall experience was great, and I highly recommend Avalanche HVAC!!!
