At Westminster HVAC, we've sized and installed systems in homes across this city for years. And we know what actually drives the price up or down.

How Much Does a New HVAC System Cost in Westminster, CO?
A full HVAC replacement in Westminster falls into a few clear price bands, depending on what you're replacing:
- Furnace only: $2,800 – $7,500

- Heat pump system: $5,000 – $15,000

What Determines the Cost of a New HVAC System?
A few things decide what you'll pay for a new system. Here's what changes the price the most:
- The equipment type and brand you choose
- The efficiency rating, measured in SEER2 for cooling and AFUE for heating
- Your home's square footage and layout
- Labor costs and local permitting fees
- Whether your ductwork works as-is or needs replacing
Bigger homes need bigger systems, and Colorado's altitude changes how we size a unit compared to sea level. Most of the time when this happens in Westminster, the system we're replacing already passed the fifteen-year mark. Homeowners call about a strange noise or a weak flame. We often find a cracked heat exchanger underneath — a sign it's time for something new, not another repair.
Average Cost by System Type in Westminster, CO
Every home is different, but most Westminster replacements fall into one of four categories:
| System Type | Estimated Cost Range |
|---|---|
| Furnace only | $2,800 - $7,500 |
| Central AC only | $3,000 - $8,000 |
| Heat pump system | $5,000 - $15,000 |
| Furnace + AC combo | $6,000 - $15,000 |
A ductless mini-split can work as a lower-cost alternative if you don't have ductwork already in place. Heat pumps have grown popular here too, since they handle both heating and cooling in one system.
How Home Size and Existing Ductwork Change the Price
Two homes of the same size can still get very different quotes. Ductwork usually explains why.
- Bigger square footage means a bigger unit and more tonnage
- Multi-story homes cost more to install in than single-story homes
- Old or damaged ductwork adds inspection and repair costs
- Older homes around Westminster often have outdated duct systems that weren't built for today's equipment
- Hard-to-reach attics or crawlspaces slow the job down and raise labor costs
If your ducts are in rough shape, that cost shows up before the new equipment even gets installed.
Extra Costs Homeowners Often Forget to Budget For
The equipment price on your quote isn't always the full story. A few line items tend to show up later:
- Electrical panel upgrades for higher-efficiency units
- Permitting fees through the city
- Removing and hauling away your old equipment
- A new or updated thermostat
- Warranty registration or a maintenance plan
One thing we see constantly on Westminster calls: a family budgets for the new furnace. Then they find out mid-install that the electrical panel can't handle the higher-efficiency unit. That upgrade isn't optional once we're already inside the wall.

Ways to Lower Your HVAC Replacement Cost
A new system is a big purchase, but there are ways to bring the price down:
- Ask about current Xcel Energy rebate programs for high-efficiency equipment
- Look into financing or payment plans through your contractor
- Schedule installation in spring or fall, when demand is lower
- Bundle your furnace and AC replacement into one job instead of two
What homeowners don't realize is how much rebate money gets left on the table. We've sat at kitchen tables filling out Xcel paperwork with customers so they don't miss a dollar of it.
How to Know If You Need a Full Replacement or Just a Service Call
Not every furnace or AC problem means a full replacement. Here's a quick way to tell:
Signs you probably need a full replacement:
- Your system is 10 to 15 years old or older
- You've paid for two or more repairs in the last year
- Your energy bills keep climbing even though you haven't changed how you use the system
Signs a service call might be enough:
- The problem just started
- It's the first issue you've had with this system
- Everything else in the unit still runs fine
Most of the time, a stuck flame sensor or dead capacitor gets blamed on "the whole system dying." A short diagnostic visit proved the furnace still had good years left in it.
