The installers were fast and cleaned up after themselves. Sean was very knowledgeable and very professional. Carlos was the hardest worker I have ever seen. The other guy was a hard worker too. They were amazing! Renee was very knowledgeable and professional. She came out last minute and late at night to take care of my family. Another company was trying to tell me that I HAD to replace both of my systems and I couldn't even get a word in. Completely night and day from their scare tactics and Renees honesty. She said why would I replace a unit that is not broken. Very genuine. I love Comfort First and will be referring them to my friends and family. I was actually referred by my neighbor who just had a system installed by them too!
