I was very satisified with the work and the 2 employees who did the work.
I had to have a furnace replaced due to a carbon monoxide leak, and decided to also replace the a/c to be more energy efficient. I have used Sierra Air before and felt they would do a good job for me. They did and they came out when they said they would. Their employees that did the installation did an excellent job and cleanup as well. I would recomment them to anyone that asked.
