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!

We have had our a/c and heating systems serviced by T.J. Fannon & Sons for over 26 years now in our three different primary residences in Fairfax County. Everyone who has ever provided service to any of our homes has been nothing but friendly, courteous and very professional (to include the people in the office). Fannon follows the job through to completion each and every time. Whenever anyone asks who we go to for a/c and heating problems, we always highly recommend Fannon!

I've used TJ Fannon for 15 years for HVAC and hot water heater. Do not need fuel oil. Have found them to be knowledgeable & meticulous in repair/replacement, & extremely helpful in an emergency--104 degrees & the a/c goes down or today when the hot water heater burst. Also honest in telling me that my problem with my heat was the thermostat (probably the original in a 50 y.o. house) and to go to Home Depot to replace for $20. I did get a bill for the service call, too, but I expect that.

They cleaned our oil burning furnace and inspected it prior to our move.Technician came SAME day, was thorough and kind to our handicapped dog. he accidentally left a little oil soot on the stair runner. I left a VM and the owner called me back promptly the next day and sent a fantastic lady to clean the carpet thoroughly. We've used them for years to both service our furnace and purchase our oil. Would recommend them to anyone!

A big shout out to the wonderful business and greet people at TJ Fannon and Sons. I know this is a very busy week, with the coldest of temperatures, and they are getting many emergency calls. I called last evening and left a message (non-emergency) for them to come out and get our furnace running this morning (we had enough heaters to keep ourselves comfortable through the night ). Not too long after their office opened, I received a call from them. Their technicians showed up an hour later, changed the clogged valve nozzle, put on a new filter, and gave everything a once over. After making sure things were firing properly, were out the door in about 30 minutes. Many in the community depend on them for heat and comfort throughout the year. They are truly unsung heroes. I sincerely appreciate your constant and dependable reliability.
