DeMasco is great! Frank accurately diagnosed, explained everything as he did it and was able to fix my 20+ year old split system unit, saving me a very expensive replacement job. I will definitely call them again if/when need arises!

I have been using Demasco since 2002. When one company told me I needed a new air conditioning unit, I called for a second opinion and Demasco had been recommended by my community. A loose wire and free-on was all that was needed. Frank is honest and trustworthy. He gets the job done right and I never have to worry. I've recommended him to many and they've all been happy with the service he provides.
