"The overall Sila team was great from the debugging of the issue, explaining the options and replacing the HVAC unit. There were multiple sila techs that helped out which we’re all great and Guy spent time explaining the new unit after it was installed and we learned a lot about our new unit."

"Great company to work with. They're very thorough on what needs to be done to fix a problem and are very professional. So far they've done two repairs to my heating system and were always pleasant and willing to help. Keith and Ron are great guys and I'll be calling them for my HVAC needs."

"

I called Kris U. in a panic because an unethical contractor had totally messed up our very expensive HVAC system, and the condensers had been sitting unconnected for 18 months! Called Sila, they had no idea what to do. Called Kris and he sent in Gregg H. to reconnect everything, drain the condensers and recharge them again. He did a great job and it turned out we did not have to buy new condensers -- hooray!

I highly recommend this company, since no one else was willing or had the inclination to tackle this.
