What's included

What's Included in a Furnace Replacement

Every replacement we do covers the full job, not just the equipment. You get removal, install, testing and cleanup in one price. Duct redesign, added venting runs or electrical panel upgrades are quoted separately if your home needs them, and we tell you before we start.

01

Removal and Haul-Away

We disconnect the gas and power, pull the old furnace, and haul it away. No old cabinet left in your garage and no disposal fee tacked on at the end.

02

New Furnace and Controls

The furnace itself, sized to your home with a Manual J load calculation, plus a new thermostat or wiring to your existing one. We set gas pressure and confirm temperature rise before we leave.

03

Flue and Venting Work

New flue pipes or a PVC vent conversion for high-efficiency units, installed to code with correct pitch and clearances. We verify draft with a combustion analyzer on every job.

04

Duct and Plenum Sealing

We seal the plenum and accessible duct joints with duct sealant so the air you paid to heat actually reaches your rooms instead of leaking into the basement.

05

Combustion and Safety Testing

Gas pressure checked with a manometer, temperature rise with a thermometer, and flue gases with a combustion analyzer. If anything reads off, we correct it before we call the job done.

06

Filter and Walkthrough

A fresh furnace filter goes in, and we show you the size, the change interval and the warranty terms. You leave knowing how to run and maintain the new system.

Service overview

Furnace Replacement Loveland CO: What the Job Really Involves

Furnace Replacement Loveland CO is the full removal and reinstall of your home's heating plant, not a patch on a dying unit. We shut off the gas, disconnect the flue pipes and ductwork, pull the old cabinet, then set and level the new furnace. From there it's a new gas valve connection, fresh flue pipe, sealed plenum, thermostat wiring and a combustion analyzer test to confirm the unit is burning clean before we hand you the keys.

Most replacements we run in Loveland are on furnaces 15 to 25 years old, and they usually fail at the worst time. A cracked heat exchanger, a blower motor failure or a furnace lockout that keeps tripping is the point where repair stops making sense. If you're weighing a new furnace installation Loveland CO against another round of parts, we'll show you the numbers and let you decide.

Lower Monthly Gas BillsModern 96% AFUE furnaces burn far less gas than the 80% units common in Loveland's older housing stock. On a typical 2,000 sq ft home, that difference often shows up as $30 to $60 a month through winter. Over a Loveland heating season, the savings add up fast.
Heat That Reaches Every RoomWhen we size the new furnace with a Manual J load calculation and seal the plenum and duct connections, the far bedrooms stop running cold. No more space heaters in the back room. No more thermostat set to 74 just to feel 68 upstairs.
Fewer 2 A.M. BreakdownsA furnace blowing cold air or short cycling at midnight is what pushes most people to replace. A new unit with a fresh igniter, thermocouple and control board takes that risk off the table. You get a warranty and a system that starts every time.

The service timeline

How Our Furnace Replacement Process Works

The process flexes to the condition, but these checkpoints keep decisions clear.

01

Call and Schedule

You call 970 489 0849 or book online. We ask about the furnace age, the symptoms and your home size, then set a window that fits your day. Most Loveland calls get a same-day or next-morning slot, and emergency replacements get priority when the house is without heat.

Stage 1
02

On-Site Assessment

A NATE-certified tech inspects the old furnace, checks the heat exchanger, flue pipes and ductwork, and measures the home for a Manual J load calculation. You get a straight answer on whether repair still makes sense or replacement is the better spend.

Stage 2
03

Sizing and Quote

We match the furnace to your actual load, not a rule of thumb. You see the equipment options, the efficiency ratings and the total price before anything is ordered. No surprise line items after the truck is unloaded.

Stage 3
04

Removal and Install

We cut the gas and power, pull the old unit, and set the new furnace on a level pad. New flue pipe, sealed plenum, thermostat wiring and a fresh filter go in. A standard swap runs four to six hours; add time for duct modifications or a high-efficiency vent conversion.

Stage 4
05

Test and Walkthrough

We fire the furnace, check gas pressure with a manometer, confirm temperature rise with a thermometer, and run a combustion analyzer on the flue. Then we walk you through the thermostat, the filter size and the warranty paperwork before we pack up.

Stage 5

Tools & methods

Tools and Methods We Use on Every Install

Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.

01

Combustion analyzer

Measures flue gas oxygen, carbon monoxide and temperature so we can confirm the new furnace is burning clean and venting correctly before we leave.

02

Manometer

Checks inlet and manifold gas pressure against the manufacturer's spec, which is the difference between a furnace that runs and one that runs safely.

03

Multimeter

Tests control board voltage, thermostat circuits and limit switches during install and on any no-heat callback.

04

Thermometer

Confirms temperature rise across the heat exchanger, so we know airflow and firing rate match the unit's rating.

05

Inspection camera

Lets us look inside the heat exchanger and flue on the old unit, which is how we confirm a crack before recommending replacement.

06

Nut driver set and fin comb

Used for cabinet work and straightening coil or fin damage so airflow stays unrestricted after the new unit is set.

07

Vacuum gauge

Checks static pressure and airflow through the ductwork, which tells us whether the existing ducts can handle the new furnace.

Use cases

When Loveland Homeowners Replace Their Furnace

These examples show how the service framework adapts rather than forcing every call through one repair.

Furnace Replacement
22-Year-Old Furnace to 96% CarrierA Downtown Loveland home had a 22-year-old 80% furnace with a cracked heat exchanger and a blower motor on its way out. The house ran cold in the back bedrooms and the gas bill spiked every January. → We installed a 96% AFUE Carrier with a sealed plenum and new flue. Temperature rise came in on spec, and the homeowner reported about $50 a month lower gas use through the first winter.

Short Cycling Fixed in Mariana Butte

A two-story Mariana Butte home had a furnace that short cycled every few minutes and never heated the upstairs above 66 degrees. Two prior quotes recommended a larger furnace. → A Manual J load calculation showed the existing unit was oversized. We installed a correctly sized two-stage Trane, sealed duct joints and balanced airflow. Upstairs now holds temperature with the thermostat at 70.

Same-Day Swap for a Boyd Lake Rental

A rental near Boyd Lake lost heat on a Friday with tenants in place. The furnace was making banging noise and locking out, and the owner needed it fixed without a week of downtime. → We assessed Saturday morning, confirmed the heat exchanger was compromised, and installed a new Rheem the same day. Tenants had heat by evening and the owner got a documented install for the property file.

Problems we solve

Problems a New Furnace Solves for Loveland Homes

Most replacements start with a symptom you've been living with for a while. Here are the ones we see most in Loveland, and what happens if you keep putting them off.

ISSUE

Furnace blowing cold air all winter

We diagnose the cause first. If the unit is past its service life, we quote a replacement sized to your home and install it, often the same day. You get heat that actually reaches the thermostat setpoint.

SYMPTOM

Furnace short cycling on and off

We check the limit circuit, airflow and sizing. If the unit is oversized for the ductwork, a correctly sized replacement fixes the cycling and evens out the heat across your rooms.

SIGN

Furnace lockout that keeps tripping

We test gas pressure, flame sensor and draft. When repairs stack up past the value of the unit, we walk you through replacement options with upfront pricing and no pressure.

ALERT

Furnace leaking water near the base

We clear and repair the drain path, and if the cabinet or heat exchanger is compromised, we replace the unit and set up the condensate drain correctly so it doesn't repeat.

Pricing process

What Furnace Replacement Costs in Loveland

$3,800 - $7,500 installed, depending on size, efficiency and any duct or vent work

Phase 01

Furnace size and BTU

A larger home needs more BTU output, which means a bigger cabinet and higher equipment cost. A Manual J load calculation tells us the right size, so you don't pay for capacity you don't need.

Phase 02

Efficiency rating

An 80% furnace costs less upfront. A 96% condensing unit costs more but cuts gas use and may qualify for utility rebates, which shortens the payback period.

Phase 03

Duct and flue work

If your existing ducts are undersized or the flue needs a liner or PVC conversion, that adds labor and materials. We scope it before the job so there are no surprises.

“Our 22-year-old furnace quit on a Friday night in January. I called Saturday morning and they had a tech out by noon. He showed me the cracked heat exchanger, quoted a new 96% Carrier, and had it running by 6 p.m. the same day. House was warm that night. Price was exactly what he quoted.”

★★★★★
“We had three companies quote a replacement and two tried to sell us a bigger furnace than we needed. Loveland FurnaceRepair actually ran a load calculation and recommended a smaller two-stage unit. Gas bill dropped about $45 a month and the upstairs finally heats evenly. No pressure, no upsell.”
MT
Marcus T.Homeowner, Mariana Butte
★★★★★
“Old furnace was short cycling and the house never got above 66. They replaced it with a Trane, sealed the plenum and fixed a bad duct run they found during the install. Took about six hours. They walked me through the thermostat and the filter size before leaving. Would call them again.”

Frequently Asked Questions About Furnace Replacement

Furnace Replacement
Call 970 489 0849
How much does Furnace Replacement Loveland CO cost?

Most standard replacements in Loveland run $3,800 to $7,500 installed in 2026, depending on furnace size, efficiency and whether duct or flue work is needed. A basic 80% single-stage swap sits at the low end. A 96% two-stage or modulating system with a vent conversion sits higher. We quote the full price before we start, including permit and haul-away.

How long does new furnace installation take in Loveland?

A straightforward swap takes four to six hours, so most homes have heat back the same day. Jobs that need duct modifications, a new flue liner or a high-efficiency PVC vent conversion can run eight to ten hours and may stretch into a second day. We tell you the expected window when we quote the job.

Who offers same-day Furnace Replacement Loveland CO?

We do, when the schedule and parts allow. Call 970 489 0849 before noon and we'll tell you honestly whether a same-day new furnace installation Loveland CO is realistic for your home. We keep common furnace sizes on the truck, so many no-heat calls turn into a completed replacement the same day.

What size furnace do I need for my Loveland CO home?

Size comes from a Manual J load calculation, not square footage alone. We measure insulation, window area, ceiling height and air leakage, then match the BTU output to that load. A typical 1,800 to 2,200 sq ft Loveland home usually lands between 60,000 and 80,000 BTU, but a well-sealed house can need less.
