When the furnace quits in January, you need someone who picks up and gives you a straight answer. We’ve kept Lancaster County homes warm since 1961, and we install furnaces sized to your actual home and backed by a real guarantee.

Sized to your home, not the old one

We run a real load calculation before we quote a new furnace — your square footage, layout, insulation, and windows. A right-sized furnace heats evenly, runs quieter, and lasts longer. Oversizing is one of the most common install mistakes, and it’s one we don’t make.

Equipment we stand behind

We’re an authorized dealer for Amana and Rheem — dependable heating equipment we’re glad to put our name on. Because we’re your plumber too, we handle the gas and venting side cleanly instead of leaving the awkward parts for someone else.

We know these older homes

A lot of houses around here weren’t built with modern heating in mind — tight spaces, older ductwork, additions that were never balanced. Sixty-five years in these neighborhoods means we’ve seen it and we know how to make a new furnace work in a house with some history to it.

Questions we hear a lot

When is it worth replacing a furnace instead of repairing it?

If your furnace is over fifteen years old and needing repairs most winters, replacing it usually costs less over time — better efficiency, fewer breakdowns, and steady heat. If it still has good life in it, we'll tell you that instead.

Do you do a load calculation for a furnace too?

Yes. Heating gets sized just like cooling — to your home's actual size, layout, and insulation. An oversized furnace short-cycles and wears out; a right-sized one runs steady and lasts.

“Tom Falk Plumbing has been our plumber for 30+/- years.  They have always attended to our needs in a timely manner.  Both the quality provided and the professionalism of their team has secured our loyalty.  Today we met Jim who maintained that same integrity.  He was courteous, kind, informative and ensured that no trace of water or debris remained after replacing our water heater.  Many thanks Jim!   A family owned small business one can trust and be confident in for a positive outcome.”

“Incredibly grateful for Tom Falk plumbing and their help with getting our water back on! We called end of the day which was not ideal, but they made time to come out anyways and fit us in. Within 4 hours of calling we had running water again. Couldn’t ask for better service. Definitely recommend.”
