What we do
Pittsburgh HVAC Services, Done Right
Furnace and boiler repair, AC, heat pumps, installs, air quality, and 24/7 emergencies — by licensed, EPA-certified technicians with honest, flat-rate pricing.
Werth-Aire is a full-service HVAC contractor for Pittsburgh and the North Hills, which means one honest, licensed team handles whatever your home or business needs — the 2 a.m. no-heat call, the humid-summer AC repair, the historic-home boiler, and the planned high-efficiency upgrade alike.
Pittsburgh sits in heating-dominated IECC Climate Zone 5A, and its older housing, hilly terrain, and humid summers all shape the right heating and cooling decision. Every service below is delivered by EPA-certified technicians with a real diagnosis, flat-rate written pricing, and the proper permits — no guesswork and no pressure to replace when a repair will do. Browse by category, or tell us the symptoms and we'll point you to the right fix.
