Best Heating and A/C company in the DMV! I have gone through my share of Heating and A/C companies and I have never found one as attentive and quick responding as TJ Fannon & Sons. I have had multiple problems with a gas furnace with multiple prior companies. Fannon came, installed and live up to their workmanship. Their service plans are reasonable and they always show when they promise. I am sure they will have the occasional hiccup, but that happens. When it comes down to laying down my hard earned cash for Heating and A/C, Fannon will be first in my book when it comes to quality work, prompt service and knowledgeable technicians! GREAT JOB FANNON & SONS!
