Brandon Freed Came to Our Rescue
Brandon Freed came to our rescue after our furnace went out. He was polite, professional, and knowledgeable. He helped us get our home warm again in time for the next cold front. We're going to need a new system soon, and hopefully we can do business in the future. Thank you, Brandon and Allen Service!

We Cannot Recommend Him Enough
We called Allen Service the moment we noticed our furnace wasn’t working properly, and they had an expert to our house within a few hours! Justin Adams was our technician and we cannot recommend him enough. He was professional, friendly, transparent, but most importantly, he was informative! He walked us through each step of the process and gave us a variety of options and suggestions for solutions they could provide. We’ll absolutely be contacting Allen Service for future services for our home!!
