Very happy with the experience!
I had been having intermittent issues with my AC unit and it finally stopped working. I called and someone was dispatched and arrived within an hour of scheduling. Brandon Freed was extremely nice and kept me informed of the problems as he worked. He was able to get my 25 year old system working again. I will need to replace the unit soon but for the time being he was able to get it working! Very happy with the experience!

Thorough, Honest Work from Zach
I started with this company when they were NOW in 2012, and 13 years later, I have no regrets. I've had different service reps work on my furnace and condenser during that time. This is a review for the latest rep. Zach has been doing the inspections on the furnace and condenser for the past year. He always explains what he finds, including the pictures and all of the data. He just finished work on the condenser and showed me all of the current data and the data from the last inspection and how they compared to each other. He is always very thorough in his work and always polite. If you want someone who will do thorough, honest work for you, Zach's your man.

Did an amazing job
Julian Martinez with Quality First Plumbing/Allen Services did an amazing job checking out my furnace and A/C. He's very knowledgeable and able to talk you through everything he's doing with each step. He was very thorough and checked everything. He was also great with my crazy dogs and kids. I felt good about the whole experience. Thanks Julian and Quality First!
