HVAC Furnace Installation and Replacement in Pittsburgh, PA

When a Pittsburgh winter hits and your furnace stops keeping up, you don't have time to wonder whether a repair is worth it or whether a new system will even fit your basement. Impact HVAC handles furnace installation and replacement for homes throughout Pittsburgh, Mt. Lebanon, and Dormont, including the older row houses and hillside properties where a straightforward swap is rarely straightforward. Whether your current unit is 20 years old and limping through January or it finally gave out overnight, the goal is a properly sized, correctly installed system that heats your home reliably without leaving you guessing about what you paid for.

Pittsburgh's Zone 5A climate means furnaces here aren't running occasionally — they're running hard from November through March, cycling through freeze-thaw swings that wear on igniters, heat exchangers, and ductwork connections faster than homeowners expect. A furnace that was borderline last spring may not make it through February.

What a Furnace Replacement Actually Covers

A furnace installation isn't just dropping in a new unit. It starts with sizing your home correctly, because an oversized furnace short-cycles and an undersized one never quite catches up on the coldest nights. Impact HVAC installs both gas and electric furnaces and handles the full scope: disconnecting and removing the old equipment, making any needed duct or flue connections, and verifying that the new system is running at the right airflow and temperature before leaving. Old equipment gets hauled away. If your home needs any electrical or gas line adjustments to support the new unit, that gets addressed as part of the process, not discovered after the fact.

Signs Your Furnace Has Reached the End

Most furnaces have a lifespan of 15 to 20 years, and the signs they're done tend to cluster: rising gas bills without a change in usage, uneven heat from room to room, a heat exchanger that's cracked or corroded, or a system that's been repaired multiple times in the past few seasons. If your repair costs are approaching half the price of a replacement, or if a technician has flagged a heat exchanger issue, replacement is usually the more honest recommendation. A system that keeps breaking down in January is a liability, not an asset.

What Older Pittsburgh Homes Demand from a Furnace Install

Homes built before 1960 make up a significant share of Pittsburgh's housing stock, and many of them were never designed with modern HVAC in mind. Cramped mechanical rooms, low basement ceilings, original ductwork that runs in unexpected directions, and tight access points on hillside lots all add complexity that a one-size-fits-all approach can't handle. In neighborhoods like Dormont, where brick construction and narrow lots are the norm, getting equipment in and out without damaging finished spaces takes planning. Mt. Lebanon homes from the postwar era often have ductwork layouts that need adjustment when moving from an older, lower-efficiency unit to a modern 96% AFUE furnace with different venting requirements. Impact HVAC pulls the necessary permits and coordinates inspections, so you're not left holding liability questions after the job is done.

What to Expect When You Schedule

The process starts with a free estimate that covers what your home actually needs, not a ballpark that grows once work begins. You'll get a clear breakdown of equipment, labor, and any related work before anything is approved. On installation day, the crew handles removal, installation, and cleanup. Before leaving, they verify the system is heating correctly, walk you through the thermostat settings, and answer questions about filters, maintenance schedules, and what to watch for in the first few weeks. Licensed, insured, and familiar with Pittsburgh's permitting requirements, Impact HVAC treats a completed install as one that's confirmed working, not one that's just mechanically connected.
