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.

“Fantastic company! They have done plumbing repairs and have installed a new HVAC system in my house. They listened attentively to my concerns and answered with feedback and suggestions in a way that I understood the whole process.”
Susan Frese, Google
“Tom Falk plumbing has helped us for over 20 years. Their response to calls is very prompt, and needed work is explained and then done efficiently. Recently Jeff proactively replaced our very old main water shut off valves. A few years ago they solved a complicated problem with a century-old bathroom drain pipe. Work areas are carefully cleaned when they're finished. Highly recommended.”

“I wasn’t actually there to meet the guy(s) my dad was. They were late but that’s because their scheduling system didn’t put me on eventhough there was a verbal agreement over the phone. Nevertheless, I recieved professional service and my old AC unit was repaired in a very timely manner and it’s working great! Thank you!”
