ACSI Boiler Repair Service

about your boiler or any other type of fuel-burning equipment?
Are you seeing (or smelling) that nasty, money-wasting, hard-to-clean soot? Did you know that it takes 10 cubic feet of air to burn just one cubic foot of natural gas, and without that mix, soot happens?

But it doesn’t have to happen to you.


Improper fuel-to-air mixture. (Fuel can’t burn completely without the right mix).
Burner linkages that have slipped or out of adjustment. (These often hide).
Dirty fans, which lead to a dangerous fuel-to-air mixture. (Soot happens).
Faulty fuel regulators (another common cause of sooting).
Closed or partially blocked fresh-air louvers. (If the air can’t get into the equipment room, the fuel can’t burn properly and soot happens.)

I could go on, and we will… with a thorough checklist, when our trained professionals visit your building. But for now, I just want you to know that if you see or smell soot, something is seriously wrong – something that can lead to an explosion!
Please call me for a FREE evaluation. We will make recommendations that will both, keep you safe and save you money this winter… and in the years to come!
