The city has multiple incentives to help those considering building electrification. Replacing central air conditioning and/or aging gas-fired systems with electric heat pumps creates better outcomes for occupants, owners, and the climate.
I know I want to electrify my building!
If you know you want to electrify your air conditioning, furnace, or water heating equipment and feel comfortable with your options, the Equipment Rebate would be the best option for you. These rebates directly offset a portion of the cost to install electric heat pumps in your building. Rebates are currently available for:
- Heat pump rooftop units (HP RTUs)
- Split air-source heat pumps (ASHPs)
- Mini-split air-source heat pumps (mini-splits)
- Heat pump water heaters
I am curious about building electrification, but I'm not sure if it's right for me.
If you are still not sure about converting your building equipment to electric alternatives, you may find value in pursuing an Electrification Feasibility Report. The city offers rebates to cover the cost of this process. The Electrification Feasibility Report:
- Gives you information about whether replacing your air conditioner or gas-fired heating equipment with a heat pump is cost-effective compared to a like-for-like replacement.
- Serves as a requirement when pulling a permit to install gas-fired space or water heating equipment.
I am curious about building electrification, but I'm not seeing the equipment rebate I need.
Consider applying for the Building Electrification Pilot Program if you are interested in upgrading your air conditioning system, furnace, or hot water heater to a heat pump, but you either:
- Don't see an Equipment Rebate that will work for you OR
- Aren't sure about which Equipment Rebate is right for you
This program will help you:
- Assess opportunities for electrification in your building.
- Choose appropriate equipment replacements.
- Assess price quotes and scopes of work from contractors.
- Offset the costs of assessing and installing electric equipment.
- Identify additional rebates and financing.
Please note that there are limited spots in our Pilot Program.
I still don't know what to do.
If you are unsure which program is right for you, please reach out to Michaels Energy, our electrification program administrator, at DenverElectrification@MichaelsEnergy.com or 720.782.7661. They will be happy to assist you.

Common Heat Pump Terms
Backup/Supplemental/Auxiliary Heating |
A secondary heating system that works with your heat pump to provide heat below a specific outside air temperature. |
Cold Climate Heat Pump |
Heat pumps with better efficiency and capacity at lower outside air temperatures, well below freezing. Cold Climate Heat Pumps operate reliably at 5°F, and some as low as -15°F.
Often abbreviated as CASH (Cold Climate Air Source Heat Pump) or ccMSHP (Cold Climate Mini Split Heat Pump)
|
Coefficient of Performance (COP) |
A common efficiency metric, simplified for energy out / energy in. Higher is more efficient, indicating that more energy goes into the home relative to the energy supplied by the utility. Combustion appliances like furnaces always have a COP of less than 1, electric resistance heat has a COP of 1, while heat pumps can have a COP upwards of 4. |
Dual Fuel |
An HVAC system that uses both electricity and gas to supply heat. |
SEER/EER/HSPF and SEER2/EER2/HSPF2 |
SEER - Seasonal Energy Efficiency Ratio:
- An indicator of cooling energy efficiency throughout a cooling season, a higher value indicates better efficiency
HSPF - Heating Seasonal Performance Factor:
- An indicator of heating efficiency throughout a heating season, a higher value indicates better efficiency
EER - Energy Efficiency Ratio:
- A snapshot of cooling efficiency at 95° outdoor air temperature.
"SEER2/HSPF2/EER2" – as of 01/01/23, the Department of Energy has created new standards to reflect testing procedures that more closely mimic real-world conditions. This change should result in tested efficiencies that are closer to actual performance.

Heat pumps are an energy-efficient alternative to central air conditioning, gas-burning space heating, and water heating equipment in all climates. That's right; heat pumps can heat AND cool your home. Like a refrigerator, heat pumps use electricity to transfer heat from a colder space to a warmer space rather than generating heat.
- In winter, heat pumps gather heat from the outdoors and move it into your building to warm it.
- In summer, heat pumps collect heat from your home and transfer it outside to cool your building.
- Heat pump water heaters collect heat from the area outside of the unit and use that heat to heat water.
Since heat pumps move heat instead of creating it, they achieve 200-300% efficiency. While natural gas is currently less expensive than electricity, more efficient heat pumps use 2-3 times less energy than gas heating systems.
Heat Pump Rooftop Units
A heat pump rooftop unit is a type of Heating, Ventilation, and Air Conditioning (HVAC) system. They are often installed on the roof of a commercial or industrial building, but they can also be ground mounted.

These units provide both heating and cooling to the building using heat pump technology. They extract heat from the outside air during the winter and release heat outside during the summer. Rooftop units usually either have a gas or electric resistance backup heat source. Heat pump rooftop units typically contain:
- A compressor
- A reversing valve
- A fan
- A heating and cooling coil
- A back-up heat system
- Controls that regulate the temperature and airflow
Split Air-Source Heat Pump
A split air-source heat pump system has two parts: an outdoor unit and an indoor unit. The outdoor unit contains a compressor, a fan, and a coil, while the indoor unit contains a fan and a coil. Refrigerant lines connect the two units to transfer heat between them. Often, these units use existing ductwork and air handlers in a building and replace a furnace and an air conditioner.
During the winter, the split air-source heat pump extracts heat from the outside air and transfers it to the indoor unit. The indoor unit then distributes heat throughout the building. During the summer, the process is reversed, and the heat pump extracts heat from the indoor air and releases it outside.

Mini-Split Heat Pumps
A mini-split system has two components:
- An outdoor heat pump unit
- Indoor head(s) that deliver hot or cold air
Refrigerant lines connect the two units to transfer heat between them. During the winter, a mini-split extracts heat from the outside air and transfers it to the indoor head(s) via the refrigerant. The indoor head(s) then distributes heat throughout the building. During the summer, the process is reversed: the heat pump extracts heat from the indoor air and releases it outside.

Often mini-split heat pumps are ductless, which means they need no ductwork to deliver heating or cooling to the building. Instead the indoor heads have fans and directly deliver the heating or cooling. They are often mounted on a wall or ceiling.

A mini-split is a great option to add heating/cooling to a single space in a building. They may be the most cost-effective heat pump option for buildings without ductwork or where adding ductwork is cost-prohibitive. Because each head is controlled individually, mini-splits allow you to keep different spaces at different temperatures. They can be suitable for infrequently used rooms.
Heat Pump Water Heaters
A heat pump water heater pulls heat from the surrounding air and uses it to heat water in a storage tank. They use the same technology as heat pumps that heat air and apply it to water heating instead.
