Family‑owned.
Professionally operated.
Service built around professional workmanship, fast response, and a five-star customer experience. One local company for the systems that move air, water and heat through your home.
Need someone today?
We strive to provide same-day service, with priority based on urgency and the capacity we have that day.
Plumbing trouble?
Repair, leaks, drains, sump and well pumps. Schedule a visit and we'll confirm timing when we call.
01 What we do Find your service
One company, whole house
Four things we take care of
Air, water, heat, and the water you drink. Because it's all one company, nobody gets handed off and nothing falls between two contractors.
Heating & Cooling
Furnaces, heat pumps, boilers, central air and ductless — repair, maintenance and replacement.
Plumbing
Leak repair and detection, fixtures, drain clearing, sump pumps, well pumps and pressure tanks.
Water Heaters
Tank, tankless and heat-pump water heaters — Bradford White, Rheem, Laars and Rinnai among them.
Water Treatment
Softeners, carbon filtration, reverse osmosis and UV for well water — designed around a lab test of your water.
02 What it costs Money, out in the open
Before you spend anything
Repair it, or replace it?
Three questions, then the arithmetic we'd use at our own houses — including the times the answer is keep what you have. An estimate from public Pennsylvania energy data, not a quote; a technician confirms on site.
Step 1 of 5
What do you need today?
This decides what we can quote you on the spot.
Ugo the Tree Frog has been on our trucks since 2013 — good company for the math, but the person who sizes your system is a trained technician, not a frog.
Pricing you can see before we visit
Helpful pricing. Not fake precision.
A number pulled out of the air helps nobody. Here's how we get you from a rough idea to a real price, and what happens at each step.
See the range
Educational ranges by system category, plus what actually moves the price.
Tell us the basics
ZIP, home and system type, approximate size, fuel, age, timeline.
Build your system
Comfort tier, efficiency, air quality, controls, zoning, warranty, financing.
Estimated investment
A narrower range for your configuration, and what could still change it.
Schedule the estimate
A technician confirms load, ductwork, electrical and venting on site. That number holds.

Get to know DiBiase
Joe went to trade school
before he started a company.
1996Williamson grad
2008Founded DiBiase
PA026480State licence
A growing team of local HVAC and plumbing professionals.
Joe DiBiase graduated from the Williamson Free School of Mechanical Trades — a three-year Power Plant Technology program and an Associate's Degree in Specialized Technology, with training across heating and air conditioning, plumbing and electrical. He incorporated DiBiase in 2008 and ran it out of a home office and garage.
That's why the company can add plumbing without pretending it's a new idea, and why whole-house thinking shows up in how we diagnose comfort problems instead of only looking at the equipment.
Meet JoeIn our customers' words
The reviews we're proudest of mention names.
Riley, Barry, Luis — customers remember who showed up. That's the whole business.
Had a visit from us recently? How did we do?
That's what we like to hear — would you tell your neighbors?
Then we didn't finish the job. Tell us directly — the owner reads every one of these, and we'd rather fix it than explain it.
“On the day we moved in to our house, we discovered that our AC unit needed to be replaced in the middle of a heat wave. The whole team at DiBiase has been very responsive to our needs and helpful. They were easy to work with and provided top quality equipment and service. I couldn't have asked for a better experience!”
