About Werth-Aire — Your Pittsburgh HVAC Team
Honest diagnosis, proper installation, and a crew that treats your home like our own.
Our story
Your locally owned Pittsburgh HVAC team
Werth-Aire is a locally owned and operated heating and cooling contractor based in Pittsburgh's North Hills, on the Perry Highway corridor. Since 2015, we've served homeowners and businesses across Allegheny County with one guiding principle: tell people the truth about their systems and do the work right.
That principle grew out of a frustration our own customers kept describing — contractors who pushed expensive replacements before diagnosing the real problem, quoted vague prices, or topped off a leaking AC every summer instead of fixing it. We built Werth-Aire to be the opposite: flat-rate written pricing, honest repair-versus-replace guidance, and installations sized and permitted properly.
Our EPA-certified technicians know Pittsburgh's housing — the mid-century furnaces of the North Hills, the historic boilers and radiators of the older boroughs, and the humid summers that push every AC to its limit. That local knowledge is why 51+ neighbors have trusted us with everything from a 2 a.m. no-heat call to a full high-efficiency system replacement.
How we work
What you can count on from us
Honesty over upsells
We recommend the repair when a repair makes sense, and only recommend replacement when the evidence supports it — shown to you, not just asserted.
Done right the first time
Proper load calculations, matched equipment, pulled permits, and documented startup testing. Shortcuts create the callbacks we work hard to avoid.
There when it matters
No-heat and no-cool emergencies get priority, 24/7. We give honest arrival windows and treat your home like our own.
Local accountability
We live and work here. Our reputation across Pittsburgh and the North Hills is built one honest job at a time.
What to expect
What working with Werth-Aire looks like
From the first call to the final follow-up, our process is built to remove the guesswork and the pressure. Here's how a job actually goes.
You call, we listen
Tell us the system type, the symptom, and whether it's an emergency. We give you an honest arrival window for your area — not a vague all-day promise — and safe steps to take while you wait.
We diagnose, then explain
Our EPA-certified technician isolates the real fault and shows you what they found in plain English, so you understand the problem before any work is approved.
You get a written, flat-rate price
The repair or replacement is quoted in writing before we start, with the diagnostic fee and any after-hours terms explained up front. No surprises at the door.
We do the work to code
Repairs are completed and verified; installs are sized with a Manual J calculation, permitted, and startup-tested. We clean up the work area like it was our own home.
We document and follow up
You get a record of the work, the warranty terms, and what to watch — plus a standing invitation to call us first the next time something comes up.
Credentials & standards
Qualified, credentialed, and accountable
We're happy to verify our Pennsylvania registration, insurance, and EPA Section 608 credentials on request — and we pull the proper Pittsburgh mechanical permits on installations.

Proudly serving the North Hills & beyond

Questions about Werth-Aire
What Pittsburgh homeowners say
Rated 4.9★ across 51 reviews
“Our furnace died on the coldest night in January. Werth-Aire answered right away and had a tech out that evening. He found the bad igniter, showed me the part, and had heat back on before bed. Fair price, no upsell.”
“Got three quotes for a new furnace. Werth-Aire was the only one who actually measured the house and did a load calculation instead of guessing. Install was clean, they pulled the permit, and the new system is noticeably quieter.”
“We have an old boiler and radiators, and most companies did not want to touch it. Werth-Aire knew exactly what was wrong — a stuck circulator — and fixed it same day. So relieved to find someone who understands these old systems.”
