Caroline Fluharty Genewick

Very satisfied with their work and service. Had a new system put in this week, men were super nice and laid plastic down over the carpet to keep it clean. Have used them for years and no complaints

John Williamson

I was impressed by John, the Lowery-Clarendon technician who came out to give me an estimate.
MY APPLAUSE to John and his employer for giving excellent advice even when it means they might not get a customer. That's the kind of person I like to highly recommend to others.

Norma Rogers

We have a complete new system. We love it! They came out and told us what we needed and they completely removed the old went in attic with all new. Our light bill also has been low.
