Calfo Heating, Cooling & Plumbing was founded with one goal: to bring integrity, expertise, and comfort back to the HVAC and plumbing industry in Pittsburgh. For over 15 years, we’ve proudly served our friends, families, and neighbors across the Steel City—earning trust one home at a time.

We know the problem with most so-called “pros”—rushed jobs, scare tactics, and treating people like numbers. At Calfo, we do things differently. Our technicians undergo over 10,000 hours of hands-on training and five years of HVAC schooling, with a strong emphasis not just on technical skill, but on communication, respect, and putting your needs first.

That’s why we deliver the Red Carpet Treatment—literally. Every time we visit your home, we roll out a red carpet to keep your space clean, and more importantly, to remind you that you’re getting first-class service.

Whether it’s a minor repair or a full HVAC system upgrade, we use only the best—Lennox high-performance systems—so your comfort is never compromised, and your energy bills stay low.

At Calfo, our mission is simple:
To solve your home comfort problems the right way—with honesty, quality craftsmanship, and service you’ll remember.
