A new furnace is one of the bigger purchases you’ll make as a Loveland homeowner. Most people don’t know the real range until they’re already getting quotes, and the range is wide enough to be frustrating if you don’t know why. Here’s what actually goes into the number, and what’s negotiable.
Quick Answer: Most Loveland furnace installations run $3,500 to $7,000 fully installed. Gas furnaces dominate Northern Colorado. High-efficiency 96% AFUE units cost more up front but pay back faster in a climate where you’re running heat for six-plus months a year.
What a New Furnace Actually Costs in Loveland
These are installed totals for a standard gas furnace swap in an existing home. They cover the unit, 4 to 8 hours of labor, basic flue work, thermostat hook-up, and start-up testing. Ductwork repairs or major gas line upgrades are priced separately.
| Efficiency Tier | AFUE Rating | Unit Cost | Installed Total |
|---|---|---|---|
| Entry-level | 80% | $700 to $1,100 | $2,800 to $4,000 |
| Mid-efficiency | 92 to 95% | $1,100 to $1,600 | $3,800 to $5,200 |
| High-efficiency | 96 to 98% | $1,500 to $2,400 | $4,500 to $7,000 |
What Drives the Price Up (or Down)
The unit itself is only part of the quote. These are the line items that move the total the most.
- Unit size (BTU output): Sized to your home’s actual heat load, not square footage alone. Oversized furnaces short-cycle, wear faster, and keep your humidity uncomfortably low.
- Existing ductwork condition: Leaky ducts mean some heat never reaches the rooms. Resealing or resizing adds cost but makes the new unit perform closer to its rated efficiency.
- Flue type: 80% units use a conventional B-vent chimney. 96% units need PVC exhaust piping run through a wall or the roof. That pipe run typically adds $200 to $500 depending on distance.
- Gas line condition: Older flex lines or undersized service sometimes need upgrading before a new unit can be safely connected.
- Permit fees: Loveland and Larimer County require a mechanical permit for furnace replacements. Budget $75 to $150. Any properly licensed company pulls these before work starts.
80% vs. 96% AFUE: Which One Makes Sense Here?
Loveland averages about 5,900 heating degree-days per year, roughly twice what you’d see in milder parts of the state. That matters when you’re deciding between efficiency tiers.
An 80% AFUE furnace converts 80 cents of every gas dollar into heat. A 96% unit converts 96 cents. On a $1,200-per-year gas bill where the furnace accounts for 55% of usage, that gap saves around $185 per year. Payback on the upgrade usually runs 5 to 8 years, less if gas prices rise.
There’s another angle worth checking. A 96% unit vents through PVC and doesn’t need a working chimney. If your existing flue is cracked or needs relining, the high-efficiency option can actually cost less overall once you factor in what you’d spend on chimney repairs. Get both quotes laid out line by line before deciding.
The Installation Day: What to Expect
A standard furnace swap takes 4 to 8 hours for a two-person crew. They disconnect and haul the old unit, set the new one, connect gas and electrical, run new venting if needed, test combustion at the burner, check static pressure in the duct system, and verify heat delivery at every register.
Cool Ducts pulls the mechanical permit before work starts on every job. The city inspection gets scheduled after installation. Loveland typically books those within 2 to 4 business days, so you’re not waiting weeks. Visit the furnace services page to see the full scope of what a proper furnace installation includes.
Repair vs. Replace: The Honest Math
Age is the starting point. Under 12 years old, single repair under $1,200? Fix it. Past 18 years on an 80% unit? Replace it. The efficiency gain alone often makes the math work, and you’re not betting on a machine that’s already lived past its design life.
The gray zone is 12 to 17 years. That’s where you need the maintenance history before anyone can give a confident answer. A furnace with a clean tune-up record, solid heat exchanger, and no pattern of repeat failures might have another 5 useful years. One that’s had four service calls in two seasons probably doesn’t.
Rebates and Financing in Loveland
Xcel Energy serves most of Loveland and offers rebates for qualifying high-efficiency equipment. Currently that’s up to $100 for a furnace rated 95% AFUE or higher. Apply through Xcel’s online rebate portal after installation. It takes about 20 minutes and the check usually arrives in 6 to 8 weeks.
On financing: most HVAC companies offer 12 to 18 month same-as-cash plans through lenders like Synchrony or GreenSky. A $5,500 job stretches to about $460 per month over 12 months. Compare that against a personal loan from your credit union before signing. The rate difference can be meaningful.
Getting an Accurate Quote
When you’re gathering quotes, ask for the heat load calculation and the permit number before anyone touches the old unit. Those two details tell you whether a company is doing the job right or just selling you a box.
Cool Ducts serves Loveland, Fort Collins, Greeley, and roughly two dozen surrounding communities across Northern Colorado. Call 970-405-5333 to schedule an estimate. Usually someone can get out within a day or two.
Quotes vary a lot in this market. Some of that variance is legitimate, different tiers, different ductwork conditions, different equipment. Some of it is margin. The ranges above give you a working baseline so you know when a number deserves a second look.
