We install furnaces the slow way: measure the house, calculate the load, adjust for Loveland's elevation, and give you priced options with the trade-offs in plain English.

What a furnace installation includes
- Manual J load calculation: Your home's size, insulation, windows, and layout set the size. Not the size of the furnace coming out — that one may have been wrong for decades.
- Altitude setup: At 4,982 feet, gas input is derated roughly 12% compared to sea-level ratings under the National Fuel Gas Code's standard adjustment. Orifice sizing, gas pressure, and blower settings all get set for our elevation. A furnace installed with sea-level settings here runs dirty and inefficient.
- Efficiency options with real numbers: An 80% AFUE furnace vents through a metal flue. A 96% or better condensing furnace vents through PVC and squeezes far more heat from the same gas, but needs a condensate drain. We price both where both are practical.
- Venting and safety checks: Flue sizing, combustion air, carbon monoxide testing at startup, and a full check of the gas line connections.
- Duct connection and airflow balancing: The new furnace gets connected properly and blower speeds set to your ductwork, not left at factory defaults.
- Old equipment removal: The old furnace leaves with us, including proper handling of any refrigerant equipment it was paired with.
When replacement beats repair
- The furnace is past 15 years and needs a major part like a blower motor or control board
- The heat exchanger is cracked — that is an automatic replacement, no exceptions
- You are paying for a repair every winter now
- Some rooms stay cold while others overheat
- Gas bills climb every year while comfort stays flat
One guideline contractors use: multiply the repair quote by the furnace's age. Over $5,000, replacement usually wins. Another: if a repair costs more than half the price of a new furnace on a unit past mid-life, replace it. We will show you both sets of numbers and let you decide.
Furnace Installation in Loveland homes
Loveland's housing splits the install work into two clear types. Downtown and around Lake Loveland, the 1960s through 1980s ranches often have furnaces in basements or crawlspaces with ductwork from the same era. Many of those homes lost original equipment in the 2013 flood or replaced it right after, which means a wave of furnaces in the Thompson Valley is now 12-plus years old and entering the wear-out years. Crawlspace installs take longer and the estimate should reflect that honestly.
In Centerra and the east-side subdivisions, installs are straighter work: modern ductwork, good access, gas and electric already sized right. There, the real decision is efficiency tier and whether to pair the furnace with a heat pump for dual-fuel heating, which suits the valley's mix of gas and electric rates well.
West toward Mariana Butte and the Carter Lake road, homes are larger and more spread out, and many run propane instead of natural gas. Propane conversions need the right kit and orifice setup, and we handle that as part of the install, not an afterthought.
What affects the cost of a new furnace
Most Loveland homeowners pay between $4,800 and $9,800 for a standard furnace replacement, and $6,000 to $9,800 for a high-efficiency condensing model with venting changes. Key factors:
- Size and efficiency tier: bigger houses and higher AFUE ratings cost more up front.
- Venting changes: switching from a metal flue to PVC venting for a condensing furnace adds labor and materials.
- Ductwork condition: crushed, leaking, or badly undersized ducts should be fixed while the equipment is out.
- Fuel type: propane conversions and gas line work add cost.
- Rebates: Xcel Energy periodically offers rebates on high-efficiency furnaces. We flag whatever is current when we write your estimate.
Estimate Your Furnace Replacement Cost
Three quick inputs, one honest planning range. These are 2026 Loveland-area market ranges — an estimate range to plan with, not a quote. Your exact number is a free written estimate after a tech sees your home.
For a typical 1,600 sq ft Loveland home, most full furnace replacements land between $4,800 and $9,800 installed. Adjust the inputs to narrow the range for a home like yours.
Planning numbers only. This range comes straight from the price bands published in our furnace cost guide, and the tool never shows a number outside them. Very large homes and full duct replacements can run above the top of the guide's range — those need an in-home quote to price honestly.
