On October 1, 2026, Xcel Energy’s Colorado rebate for cold-climate heat pumps drops from $2,250 per heating ton to $1,500 per heating ton. That is a one-third cut. On a typical three-ton system it removes roughly $2,000 from the rebate check, and the higher amount is not tied to when you sign a contract. The system has to be installed and invoiced before October 1, with the rebate application submitted by October 15.
From the day this was published, that is about four weeks, and we are installing next day through the deadline. Here is exactly what changes, what has to happen to beat the Xcel heat pump rebate deadline, and why the equipment you choose matters as much as the date.
What changes with Xcel heat pump rebates on October 1
| Equipment | Installed through Sept 30, 2026 | Installed Oct 1, 2026 and after |
|---|---|---|
| Cold-climate air-source heat pump (ducted) | $2,250 per heating ton at 5°F | $1,500 per heating ton at 5°F |
| Cold-climate ductless mini-split | $2,250 per heating ton at 5°F | $1,500 per heating ton at 5°F |
| Standard air-source heat pump | $900 per cooling ton | $600 per cooling ton |
| Heat pump water heater | $2,250 | $1,500 |
Two dates control which column you land in. The equipment must be installed and invoiced before October 1, 2026, and the rebate application must be submitted by October 15, 2026. A signed proposal, a deposit, or a scheduled install date does not hold the higher amount.
“Installed and invoiced” is the deadline that actually matters
A signed proposal does not lock in the rebate. A scheduled date does not lock it in. The system has to be running in your home with a final invoice dated before October 1. That is the whole test, and it is the part that trips people up when they wait.
It does not take long. We are installing next day, every day, through the deadline. Call, we come out for a free estimate, you approve the proposal, and the system goes in the following day with the invoice issued on completion. The deadline is fixed; our schedule is not the obstacle. The only way to miss the higher amount is to leave the call until the last few days of September, when everyone else is calling too.
Why we install variable-capacity heat pumps
The rebate is the reason to move now. The equipment is the reason it will still be a good decision in ten years. Nearly every cold-climate system we install uses a variable-capacity (inverter-driven) compressor, and the difference from a conventional single-stage unit is not subtle.
A single-stage heat pump has two settings: off and 100 percent. It runs flat out until the thermostat is satisfied, shuts down, lets the house drift, and starts again. A variable-capacity compressor adjusts its speed continuously, typically from roughly a quarter of its capacity up to full output depending on the model, so it produces exactly the amount of heating or cooling the house is losing or gaining at that moment. The Northeast Energy Efficiency Partnerships (NEEP), which maintains the cold-climate heat pump specification most utility programs are built on, describes the variable-speed compressor as the key feature of a cold-climate heat pump.
It holds its heating capacity when it is cold
This is the number that matters in Colorado. Standard heat pumps lose heating capacity as the outdoor temperature falls, which is why older units leaned on electric resistance strips or a furnace once it got cold. To carry the cold-climate designation, a system must deliver at least 70 percent of its rated heating capacity at 5°F with a coefficient of performance of at least 1.75 at that temperature, and third-party testing verifies it. The better variable-capacity units we install hold most of their rated capacity at 5°F and keep operating well below zero. Denver-area design temperatures sit in the single digits, so 5°F performance is what you should ask about, not the 47°F rating printed on the brochure.
It is efficient across the whole season, not just on the test stand
An air-source heat pump moves heat rather than creating it, which is how ENERGY STAR can state that a heat pump can deliver up to three times more heat energy to a home than the electrical energy it consumes. Variable-capacity units get more of that advantage in practice because a heat pump is most efficient at low compressor speeds, and modulating equipment spends most of the season running there. A single-stage unit spends its life at the one speed that is least efficient.
It is more comfortable, and quieter
Long, low-speed run cycles keep room temperatures within a narrow band instead of the overshoot-and-drift pattern of a single-stage system. In summer, the same long cycles pull more moisture out of the air than short blasts of full-capacity cooling, which is why variable-capacity systems feel cooler at the same thermostat setting. Outdoor units running at partial speed are noticeably quieter than a full-speed single-stage condenser, and the compressor is spared the hard starts that wear conventional equipment out.
It is what the Xcel cold-climate tier is written for
The $2,250 per ton tier requires equipment that passes the 5°F capacity and efficiency test. In practice that means variable-capacity, cold-climate-rated equipment. A standard single-stage heat pump lands in the $900 per cooling ton tier instead.
It costs less to run than the equipment it replaces
Two comparisons matter. In cooling season, a variable-capacity heat pump replaces an air conditioner that is typically 10 to 15 years old and was built to a 10-to-13 SEER standard. Today’s variable-capacity systems carry cooling ratings well above that, and because they modulate instead of cycling, they spend the summer at the low speeds where the efficiency gap is widest. Your cooling bill goes down. In heating season, through the moderately cool weather that makes up most of a Front Range winter, the days in the 30s, 40s, and 50s, the heat pump is moving roughly three units of heat into the house for every unit of electricity it uses, and it is likely cheaper to run than the gas furnace it replaces. On the coldest nights, a dual-fuel configuration lets your gas furnace take over automatically, so you get the heat pump’s efficiency where it wins and the furnace’s brute force where it is needed. Most of our cold-climate installs are set up this way, and it qualifies for the Xcel rebate.
What the full incentive stack looks like before October 1
- Xcel Energy cold-climate rebate: $2,250 per heating ton at 5°F through September 30. Xcel pays on the system’s rated heating output at 5°F, not its nameplate size, and a nominal three-ton cold-climate unit typically delivers around 32,000 BTU per hour at that temperature, roughly 2.7 heating tons. That works out to about $6,000 before October 1 and about $4,000 after.
- Power Ahead Colorado (DRCOG): $1,500 for an ENERGY STAR cold-climate heat pump installed by a verified Power Ahead contractor in the ten-county Denver metro area. This program launched this summer and stacks with the Xcel rebate.
- Colorado state heat pump tax credit: the state offers a tax credit on qualifying air-source heat pumps installed in 2026. Goodfellas is a registered contractor, so we claim the credit and pass a share of it along as an additional discount on your invoice. There is no tax paperwork on your end.
- Federal 25C tax credit: ended December 31, 2025. It is no longer available for 2026 installs.
Put together, a typical three-ton cold-climate system installed before October 1 can qualify for roughly $7,500 in combined rebates, plus the state tax credit discount on the invoice. The identical system installed on October 2 qualifies for roughly $5,500 plus the same state credit discount. The equipment, the labor, and the house are the same. Only the date is different. For the complete breakdown of every Colorado program, see our guide to Colorado heat pump rebates in 2026.
Who qualifies for the Xcel heat pump rebate
- Xcel Energy serves your home for electricity, natural gas, or both. If Xcel supplies either service to your address, you are in the program.
- Single-family homes, duplexes, and four-plexes are eligible.
- The equipment must be on Xcel’s qualifying list with an AHRI-matched indoor and outdoor pairing that meets the cold-climate criteria.
- Installation must be done by a licensed contractor. Goodfellas is a registered Xcel Energy trade partner, and we prepare and submit the application, commissioning form, and supporting documents for you.
- There is no income requirement for the base Xcel rebate.
How fast this goes
- Day one: Free in-home estimate. We measure the house, run the load calculation, size the system to its actual heating and cooling load rather than to the old furnace’s nameplate, and put the proposal in front of you with the rebate figures pulled from the AHRI listing.
- Next day: Installation and commissioning, usually finished in a single day, with the final invoice issued on completion.
- We file the Xcel application with the invoice, AHRI certificate, signed rebate form, and commissioning sheet, well ahead of the October 15 submission deadline.
That is the whole process: two days on your end, and the rebate is locked in.
Common questions
Does the rebate depend on when I sign, or when the system is installed?
When it is installed and invoiced. Equipment installed and invoiced before October 1, 2026 qualifies for the $2,250 per heating ton amount as long as the application is submitted by October 15. A signed contract or deposit before October 1 does not hold the higher amount if the install happens later.
Can I keep my gas furnace?
Yes. A dual-fuel setup pairs the heat pump with a gas furnace that runs only when it is cold enough that the furnace is the more economical choice. It qualifies for the Xcel cold-climate rebate and is a common configuration for Front Range homes.
Will a heat pump actually keep my house warm at 0°F?
A cold-climate, variable-capacity heat pump that is sized correctly will. These systems are tested at 5°F and the ones we install continue operating well below zero. Sizing is the part that matters, which is why we run a load calculation on every install instead of matching the old equipment’s tonnage.
How is “per heating ton” calculated?
Xcel pays the cold-climate rebate on the system’s rated heating capacity at 5°F from its AHRI listing, divided by 12,000 BTU per ton. Almost no heat pump delivers its full nameplate tonnage at 5°F. A nominal three-ton cold-climate unit that delivers 32,000 BTU per hour at 5°F is about 2.7 heating tons and earns roughly $6,000 before October 1, roughly $4,000 after. The exact figure comes from the AHRI listing for your specific indoor and outdoor pairing, which we show you on the proposal. This is another reason equipment that holds its capacity in the cold matters: it earns a larger rebate.
I am not an Xcel customer. What are my options?
If Xcel supplies neither your electricity nor your gas, the Xcel cold-climate rebate is not available to you, but Power Ahead Colorado and the state tax credit do not depend on your utility. We will walk you through what applies to your address.
How quickly can you install?
Next day, every day, through the deadline. Call, get the estimate, approve the proposal, and the install happens the following day. The only way to miss the higher rebate is to wait until the last few days of September. After October 1, the Xcel rebate is still $1,500 per heating ton and the other programs continue, so a heat pump remains a strong deal, but the extra $2,000 or so is gone.
Who receives the rebate check?
The rebate can be assigned to Goodfellas and applied as a discount on your invoice, or paid directly to you after Xcel processes the application. We will go over both options before you sign.
