We'll tell you honestly whether your furnace has years left or whether replacing it is the better call. No scare tactics — just proper sizing, clean workmanship, and financing options for homes across Delaware, Chester & Montgomery Counties.
Replacing a furnace is one of the bigger decisions a homeowner makes, and most people are researching it because their current system is aging, unreliable, or simply on borrowed time. You don't need a sales pitch — you need someone to look at what you have, tell you the truth about it, and lay out your real options.
Standard Services has been keeping homes warm across Delaware, Chester, and Montgomery Counties for years. When we come out for a replacement estimate, we measure the house, check the ductwork, look at the venting and gas supply, and size the equipment to the load — not to whatever happens to be on the truck. Then we walk you through the choices in plain language.
We're a family-owned, women-owned company, and that shows up in how we treat the estimate. No pressure, no fear tactics, no "you have to decide tonight." If your furnace has a few good winters left, we'll say so. If it's time, we'll show you why and hand you a clear, written proposal you can actually compare.
A single repair is almost always cheaper than a new furnace. But when several of these signs stack up, throwing money at an old unit usually means paying twice. Here's what tips the scale toward replacement.
Gas furnaces typically last 15–20 years. Past that window, parts get scarce, efficiency drops, and the odds of a major failure climb every heating season.
A cracked heat exchanger is a carbon monoxide risk and is never safely repairable. When we find one, replacement is the only responsible recommendation.
Two or three service calls in the same winter — blower motor, control board, inducer — is money better applied to a new, warrantied system.
An old 60–70% AFUE furnace burns a lot more fuel than a modern 95%+ condensing unit. If heating costs keep climbing, the unit is telling on itself.
Cold bedrooms while the living room bakes often means the furnace can no longer keep up. A right-sized, staged system evens the house out.
New rattles, booms on startup, or a blower that runs constantly point to worn internals. On a two-decade-old unit, that's the beginning of the end.
Free in-home replacement estimates across Delaware, Chester, and Montgomery Counties — with proper sizing and a written proposal you can hold on to.
Every honest contractor will tell you the same thing: there's no single price for a furnace replacement, because no two homes present the same job. Rather than quote a number that means nothing until we've seen your basement, here's exactly what moves the figure up or down — so you can walk into any estimate knowing what you're paying for.
Furnace size and efficiency tier. A properly sized 95%+ AFUE condensing furnace costs more than a builder-grade 80% model, but it burns less fuel every winter for the next two decades. The right choice depends on how long you plan to stay and how the math works for your home.
Single-stage, two-stage, or modulating. The burner and blower technology is one of the biggest cost drivers. A basic single-stage unit is the least expensive; a modulating furnace with a variable-speed blower costs more up front and delivers the most even, quiet comfort.
Whether your ductwork can carry the load. Many older Delco and Chester County homes have undersized or leaky ducts from decades of add-ons. If the duct system can't move the air a new furnace produces, we may recommend sealing or modifications so you actually get what you paid for.
Venting changes for a condensing furnace. High-efficiency units vent through PVC pipe out the rim joist or sidewall rather than up the old chimney flue. Running that new venting — and sometimes re-lining the flue for an orphaned water heater — is a real line item.
Gas line sizing, electrical, permits, and removal. A larger or higher-efficiency furnace may need a properly sized gas line and a dedicated circuit. Township permits, code-required safety devices, and hauling away the old unit all factor in. We spell each of these out on the proposal so nothing is a surprise on install day.
A number given sight-unseen is either padded to cover the unknowns or too low to be real. We'd rather spend twenty minutes in your home, measure the load, look at the venting and ducts, and hand you an accurate written estimate. It costs you nothing and it's the only way to compare bids apples to apples.
AFUE — Annual Fuel Utilization Efficiency — is the percentage of the fuel your furnace turns into usable heat over a full heating season. An 80% AFUE furnace sends 20 cents of every fuel dollar up the flue; a 96% condensing unit wastes only four. Older systems still running in the region often test out in the 60–70% range once they've drifted out of tune, which is why a replacement frequently pays a meaningful chunk of its own way through lower fuel use.
Higher AFUE isn't automatically the right answer for every home — the payback depends on your fuel type, how cold your house runs, and how long you'll own it. What matters is that you understand the trade-off, and we'll show you the difference between efficiency tiers side by side so the decision is yours, not ours.
A single-stage furnace has one setting: full blast or off. It's the most affordable option and heats a home fine, but it cycles on and off more, which can leave temperature swings and a little more noise. It's a sensible choice for tighter budgets or homes that already heat evenly.
A two-stage furnace runs on a lower setting most of the time and kicks to high only during the coldest snaps. That means longer, gentler cycles, steadier temperatures, and quieter operation — a noticeable comfort upgrade in drafty older Delco housing stock.
Modulating furnaces adjust output in fine increments and pair with a variable-speed blower to hold your set temperature within about a degree. They're the quietest, most efficient, and most comfortable option, and they make the most sense in homes where you value even heat and plan to stay for years.
If your air conditioner is aging along with your furnace, it's a fair question — and sometimes replacing both together genuinely saves money. Here's the honest version.
Your furnace and central AC share the same indoor coil and blower. When they're installed as a matched system, the equipment is engineered to work together, runs more efficiently, and the manufacturer's full warranty stays intact. Doing both at once also means paying for one install visit instead of two — the crew is already in your basement, the refrigerant lines are already exposed, and the labor overlaps.
There's also a mismatch risk to know about: bolting a brand-new furnace to a decade-old AC coil can void warranty coverage on the new equipment and leaves you with a weak link that may fail next summer. If the AC is clearly near the end, pairing it with the furnace replacement usually makes sense.
But it's not always the right move. If your AC is only five or six years old and running well, there's no reason to tear out a good unit just because the furnace died. We'll tell you plainly when combining makes sense and when it doesn't — and if you'd rather explore a heat pump instead, we'll cover that too.

From the first visit to the final walkthrough, here's exactly what to expect when Standard Services replaces your furnace.
We measure the home, run a heat-load calculation, and inspect the ductwork, venting, and gas supply — then hand you a written proposal with clear equipment options. No pressure, no expiring "today only" pricing.
We size the furnace to the actual load — not a rule of thumb — and help you choose the efficiency tier and stage type that fits your home, your comfort priorities, and your budget.
Our licensed techs remove the old unit, set the new furnace, run proper venting and any gas or electrical work, and pull the required township permit. Most replacements are completed in a single day.
We start the system, verify gas pressure and airflow, run a combustion analysis, and confirm the heat exchanger and safeties are operating correctly before the furnace goes into service.
We show you the new thermostat, register the warranty, answer your questions, and haul away the old unit. The basement is left cleaner than we found it.
