Furnace Installation & Replacement in Warrendale, PA

A furnace in Southwestern Pennsylvania puts in serious hours. The heating season runs from October into April most years, and between the damp cold, the freeze-and-thaw swings, and the stretches of single-digit nights, your system barely gets a break for six months straight.

That workload eventually catches up. When repairs start stacking up, and your bills keep climbing, replacement usually makes more financial sense than another patch job. Spurk AC, Furnace & Boiler Repair has been handling furnace installation in Warrendale, PA since 2018, and we walk you through the numbers before anything gets ordered.

We are fully licensed and insured; we size every system for the actual home rather than guessing; and our 100% guarantee backs every install.

What Your Neighbors Are Saying About Us

When my 25+ year old furnace quit running, I placed phone calls to a few local HVAC contractors. Shortly after leaving a message with Spurk, Lisa promptly returned my call and told me a technician (Chuck) would arrive within a few hours to diagnose the problem. Chuck discussed my options and recommended a furnace replacement.

Nick was awesome. He was very thorough and explained everything to me about my furnace repair. I will have him back soon to do my furnace maintenance. I called in the morning and early that afternoon the same day, Nick my technician was here. Minor issue but he got our furnace running quickly.

Charlie was at my home for a maintenance visit, and he was great!! I did not feel pressured to complete any work or repairs on my system. He gave me a full report of my system and talked me through the findings. He even talked me into a membership so I can be more diligent with my system. Great service, great company!!

Spurk replaced our old original heating and air conditioning systems. The Techs did a great job both the attic (it had to be hot up there) and basement systems over several days. Everyone was very polite, prompt and professional. We have used them for previous services, so surprises there. Thank you to the whole Spurk team!

We moved in here about a year ago and had not had AC checked. Spurk servicemen showed up and worked diligently (on likely the hottest day of the year) their whole time here. They found some issues that would have led to system shut down. Fixed that.

Top to bottom Spurk HVAC, LLC gets the job done to your satisfaction. The quote process was easy and simple, and Ethan in the front office was very helpful when it came to explanation and suggestion. Because they’re in the upper echelon of mini split installers, he was able to model out my basement to find the perfect sizing for the job.

Signs It's Time for a New Furnace

Most furnaces let you know they are winding down. Watch for these.

Furnace older than 15 years
Repair bills are adding up
Heating costs are climbing yearly
Uneven heat between rooms
Loud banging or rattling
Yellow instead of blue flame
Furnace running constantly
Excess dust in the home
Cracked heat exchanger found

A cracked heat exchanger means replacement, no question. For everything else, the general rule is that if a repair costs more than a third of the cost of a new system for a furnace over 15 years old, replacement is the better option.

How Long a Furnace Should Last

Most gas furnaces run 15 to 20 years. Some make it past that, and units that never got regular service often fall short of it. Around here, homes that get an annual tune-up tend to land at the higher end of that range, while neglected systems commonly fail somewhere around year 12 or 13.

Our climate is part of the equation. The long heating season means more run hours per year than a furnace in a milder region would see, and the humidity we deal with in basements and crawlspaces works on metal components year-round. Condensation on cold surfaces speeds up rust on heat exchangers, burners, and cabinet panels.

Installation quality matters just as much as maintenance. A furnace that was oversized for the home short-cycles constantly, which wears out the ignitor, blower, and heat exchanger years ahead of schedule. Undersized ductwork does the same thing by restricting airflow and forcing the unit to run hotter than it should. That is why we measure and calculate rather than just matching whatever was there before.

Furnace Options to Fit Your Home

Efficiency is the first decision. Standard-efficiency gas furnaces have an AFUE of around 80 percent and cost less upfront, which works for some situations. High-efficiency condensing furnaces run at 90 to 98 percent AFUE, and given how long our heating season lasts, the monthly savings often offset the price difference over the life of the system.

The blower type is the next choice. Single-stage units run at full blast or not at all, which is simple and affordable but often causes temperature swings. Two-stage furnaces run at a lower setting most of the time and kick to full power only on the coldest days, which gives you steadier heat and quieter operation. Variable speed models take that further with the best comfort, the tightest temperature control, and the strongest humidity management, which matters in a region as damp as ours.

We also install electric furnaces and heat pump systems for homes without natural gas service, as well as dual-fuel setups that pair a heat pump with a gas furnace for backup on the coldest nights. If your ductwork is undersized, poorly laid out, or leaking, we fabricate custom ductwork in-house so the new system actually gets the airflow it was designed for. A great furnace on bad ducts will never perform the way it should.

Our Furnace Installation & Replacement Process

Everything starts with an in-home evaluation. We measure the space, look at insulation and window condition, inspect the existing ductwork, check your gas line and venting, and ask which rooms have always been a problem. Then we run a load calculation to size the system properly rather than copying the old equipment.

Next, you get written options with real numbers. We explain what each system costs, what it should do for your comfort and your bills, and where the tradeoffs are. You make the decision, and we are not going to pressure you toward the biggest ticket on the sheet.

On install day, we protect your flooring, shut down and remove the old unit, and set the new furnace. That includes the gas connections, venting, electrical, condensate drain on high-efficiency models, thermostat, and any duct modifications the system needs. Most standard replacements finish in one day, while jobs involving significant duct or venting work may run into a second.

Before we leave, we start the system, check gas pressure and combustion, verify airflow and temperature rise, and confirm every room is getting heat. Then we walk you through the thermostat, the filter, and the maintenance schedule. We handle the permit and inspection paperwork, and if anything feels off in the first few weeks, just call, and we’ll come back out.

Frequently Asked Questions

How long does furnace installation take?

Most standard replacements finish in a single day. Jobs with new ductwork, venting changes, or a fuel switch may take two.

What does furnace replacement in Warrendale, PA cost?

It depends on size, efficiency rating, blower type, and any duct or venting work needed. We give written pricing after an in-home evaluation.

Is a high-efficiency furnace worth it here?

Usually, yes. Our heating season is long enough that the monthly fuel savings add up over the life of the system.

Do I need new ductwork with a new furnace?

Not always. We inspect it first, and if it is leaking or undersized, we build what the new system needs in-house.

Can you replace my furnace in the middle of winter?

Yes. We handle emergency replacements and work to keep your home protected while the new system goes in.
