Heat pump installation by type: Denver vs Longmont
We localize each heat pump installation type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.
| Type | Denver | Longmont |
|---|---|---|
| Air-source (ducted) | $8,800–$12,800 | $8,100–$11,800 |
| Ductless mini-split | $5,350–$13,950 | $4,950–$12,850 |
| Geothermal (ground-source) | $23,100–$31,100 | $21,250–$28,600 |

Heat pump installation by home size: Denver vs Longmont
Heat pumps are sized in tons like AC (roughly one ton per 500–600 sq ft), but cold-climate models may be sized up for heating. Ductless mini-splits are priced per zone instead.
| Size | Denver | Longmont |
|---|---|---|
| 1,000 sq ft (≈2 tons / 1–2 zones) | $5,950–$10,500 | $5,500–$9,700 |

Cheapest time for heat pump installation in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
