When You Need Furnace Replacement
Not every furnace problem means replacement. But there are times when patching an aging unit is throwing money at a machine that’s already decided to retire. Here’s what we tell homeowners to look for:
- Furnace is 15 to 20 years old. Most furnaces in Santa Clarita last 15 to 20 years. If yours is in that range and needs a major repair, replacement usually makes more sense than spending $1,500 on a heat exchanger with a unit that’s already on borrowed time.
- Heat exchanger crack or rust-through. This is the big one. A cracked heat exchanger can leak carbon monoxide into the house. We won’t patch one, and you shouldn’t let anyone else patch one either. This is a replacement-level repair, no exceptions.
- Repair bills stacking up. If you’ve spent $800 to $1,200 on repairs in the last two years and the furnace is over 12 years old, that money isn’t coming back. A new unit stops the bleed.
- Rooms heating unevenly. Cold spots in Canyon Country homes with high ceilings or rooms that never reach set temperature often signal a furnace that’s undersized or losing capacity. Replacement with a properly sized unit fixes it.
- Gas bill climbing without explanation. An older furnace running at 60-70 percent efficiency costs more to run than an 80 percent or 95 percent efficient replacement. In a Santa Clarita winter with cold nights in the 30s, that difference shows up every month on the SoCalGas bill.
- Constant cycling or loud operation. Short cycling, banging, or a blower that sounds like it’s dragging a chain means the system is struggling. Newer units run quieter and hold temperature steadier.
If you’re seeing any of these, the next step is a fast diagnosis. Call (661) 621-3712 and we’ll tell you honestly whether it’s a repair or a replacement. We don’t sell furnaces to people who don’t need them.
Our Furnace Replacement Process
Here’s exactly how a furnace replacement works with Dalton Heating & Air Santa Clarita, step by step:
- In-home load calculation and assessment. We measure your home’s square footage, check window orientation, insulation levels, and ceiling height, then calculate the correct furnace size. This is a Manual J load calculation, the industry standard. Skipping this step is how homes end up with furnaces that are too big or too small.
- Written quote with equipment options. You get a written price covering the furnace, labor, permits, and any ductwork modifications, with good-better-best equipment options. The price we quote is the price on the invoice. No door swings, no “we found something else.”
- Permit pulling and scheduling. We pull all required permits through the City of Santa Clarita and schedule the install inside a window we actually keep. You’ll know who’s coming because our technicians are background-checked and uniformed, and we’ll tell you their name before they arrive.
- Installation day. Our crew removes the old furnace, installs the new one, connects venting and gas lines to code, and sets up the thermostat. We check airflow, gas pressure, and safety controls before we call it done. When we leave, the area is clean. That’s not a favor; that’s The Garrison Code.
- System walkthrough and written guarantee. We show you how the new thermostat works, what maintenance looks like, and hand you the written guarantee. Every furnace replacement includes our 365-Day Done Right Promise: a full year of coverage. If it’s not done right, we make it right. In writing.
Furnace Replacement Pricing in Santa Clarita
Here are the honest numbers for furnace replacement in this area. These reflect what we see across Santa Clarita, Valencia, and Canyon Country in 2025:
| Furnace Type | Efficiency | Installed Price Range |
|---|---|---|
| Standard single-stage | 80% AFUE | $4,500 – $5,800 |
| Two-stage | 80-96% AFUE | $5,500 – $7,200 |
| High-efficiency condensing | 95-97% AFUE | $6,500 – $8,500 |
| Furnace + AC combo | Varies | $9,000 – $14,000 |
What moves the number? Three things primarily:
- Furnace size. Santa Clarita homes run from 1,200 square-foot condos in Saugus to 3,500 square-foot two-story homes in Valencia. The BTU output you need drives the equipment cost.
- Efficiency rating. An 80 percent AFUE furnace costs less upfront. A 95 percent unit costs more but drops your gas bill enough that it usually pays back the difference in 4 to 7 years.
- Ductwork and venting modifications. Switching from an 80 percent furnace to a high-efficiency unit sometimes means changing the venting setup, since condensing furnaces vent through PVC pipe rather than a metal flue. If your ducts need sealing or repair, that adds to the total.
We install Goodman, Rheem, York, and Daikin furnaces and we’ll tell you straight which one fits your budget and your house. Goodman gives you solid reliability at a lower price point. Rheem and York deliver strong mid-range value. Daikin carries excellent warranty coverage and efficiency. Our technicians are factory-trained to service those brands and five others, so you’re not getting a crew figuring it out as they go.
The estimate is free. Call (661) 621-3712 and we’ll come out, size the job, and hand you a written quote. You’re under no obligation, and the number won’t change on install day.
FAQs – Furnace Replacement
How much does furnace replacement cost in Santa Clarita?
Furnace replacement in Santa Clarita runs $4,500 to $8,500 installed for the furnace itself, with most homes landing between $5,000 and $7,000 depending on size, efficiency, and ductwork condition. The estimate is free and the price we quote is the price you’ll pay. Call (661) 621-3712 to get your written number.
How long does a furnace replacement take?
A standard furnace replacement takes one day, typically 4 to 8 hours. Larger jobs involving ductwork modifications or a full system swap can run into a second day. We’ll give you a clear timeline in your written quote so you know exactly what to expect before we start.
Is it cheaper to repair or replace a furnace?
If your furnace is under 10 years old, repair is usually the better call. If it’s over 15 years old and the repair is a heat exchanger, blower motor, or control board pushing $1,000 or more, replacement usually makes more financial sense. We’ll run the numbers with you honestly and won’t push a replacement you don’t need. Call (661) 621-3712 and we’ll give you a straight read.
Can you replace my furnace in the winter if it dies?
Yes. We keep furnaces in stock at our Santa Clarita shop and run emergency replacement crews through the winter months. If your furnace dies on a cold night when the Santa Anas are blowing and the temperature drops into the 30s, we can typically get a new unit installed within 24 to 48 hours. Our phones are answered by a live person around the clock, so you’ll never leave a voicemail and wait for a callback. Call (661) 621-3712 any time.
Do you handle the permit for furnace replacement in Santa Clarita?
Yes. We pull all required permits through the City of Santa Clarita as part of the job. The permit cost is included in your written quote, and the final inspection is scheduled by us. You never deal with city paperwork.
Why Homeowners in Santa Clarita Use Dalton Heating & Air
We didn’t start this company to be the cheapest option in town. We started it because too many homeowners were getting burned by no-shows, mystery surcharges, and half-finished work. Dalton Heating & Air has operated under The Garrison Standard since 2003, and that standard applies to every single job, including yours. It means: arrive inside the stated window, put the price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year.
Those five points are non-negotiable. They’re written down. And if the work isn’t done right, we return at no charge. That’s the 365-Day Done Right Promise, and it’s not buried in fine print.
Marco Benitez runs the Santa Clarita location, and he’s been in HVAC long enough to know that the only thing that matters is whether the system works when you flip the thermostat on. That’s the standard every Dalton technician works to.
When you call (661) 621-3712, a live person answers. You’ll get a straight answer, a fair written quote, and a crew that shows up when we say they will. That’s the whole point.
