How Heat Pumps Work
A heat pump is a heating and cooling system that moves heat rather than generating it. In winter, a heat pump extracts heat energy from outdoor air -- even when it is cold outside -- and transfers it indoors. In summer, it reverses the process, removing heat from your home and expelling it outdoors, functioning as an air conditioner.
The technology is based on a simple principle: outdoor air, even at 0 degrees Fahrenheit, still contains significant heat energy. A heat pump uses a refrigerant cycle (compressor, condenser, expansion valve, and evaporator) to capture that energy and concentrate it for indoor heating. The process is similar to how a refrigerator removes heat from food inside the unit and releases it into your kitchen.
Because heat pumps move heat rather than create it, they can achieve efficiencies of 200-300% -- delivering two to three units of heating energy for every one unit of electricity consumed. Compare that to the best gas furnaces, which top out at 95-98% efficiency. This extraordinary efficiency is what makes heat pumps such an attractive option for homeowners looking to reduce energy costs.
Cold-Climate Heat Pumps: Built for Wyoming
The first generation of heat pumps earned a reputation for poor cold-weather performance, losing heating capacity rapidly as outdoor temperatures dropped below freezing. Modern cold-climate heat pumps have solved this problem with variable-speed inverter compressors that maintain effective heating at temperatures as low as -15 degrees Fahrenheit and below.
Variable-speed compressor technology is the key advancement. Unlike older single-speed compressors that run at full capacity or not at all, inverter-driven compressors adjust their speed continuously to match the heating demand. This means the system can ramp up output as temperatures drop, maintaining comfortable indoor temperatures even during extreme cold snaps.
At Cody's elevation (approximately 5,000 feet) and with winter temperatures that regularly drop below zero, proper equipment selection is critical. We install cold-climate rated heat pumps specifically designed for extreme conditions and size them based on the Big Horn Basin's unique combination of altitude, temperature extremes, and wind exposure. Under-sizing a heat pump for Wyoming conditions is one of the most common mistakes we see from inexperienced installers.
Air-Source vs. Ground-Source Heat Pumps
Air-Source Heat Pumps
- Lower installation cost ($5,000-$10,000)
- Easier installation, no excavation
- Outdoor unit similar to AC condenser
- Cold-climate models rated to -15°F+
- Both heating and cooling
- 15-20 year lifespan
Ground-Source (Geothermal)
- Higher efficiency (400-500% COP)
- Consistent performance regardless of air temp
- Higher installation cost ($15,000-$30,000)
- Requires ground loop excavation
- 25-50 year lifespan for ground loop
- Best ROI for large homes with acreage
Air-source heat pumps are the most practical choice for the majority of Big Horn Basin homes. They cost significantly less to install than ground-source systems and modern cold-climate models perform well in Wyoming's winter conditions. Ground-source (geothermal) heat pumps offer even higher efficiency by extracting heat from the relatively stable temperature underground (about 50 degrees year-round in Wyoming), but the excavation required for the ground loop adds substantially to installation cost.
Dual Fuel Systems: The Best of Both Worlds
For Wyoming homeowners, a dual fuel system is often the ideal configuration. A dual fuel system pairs a cold-climate heat pump with a gas furnace backup. The system automatically switches between the two based on outdoor temperature and operating costs.
During moderate cold (above 15-25 degrees Fahrenheit), the heat pump provides heating at 200-300% efficiency -- far more efficient than a gas furnace. When temperatures drop below the balance point, the system switches to the gas furnace, which provides reliable BTU output regardless of outdoor temperature. The switchover point is adjustable based on local gas and electricity rates to optimize cost.
This configuration gives you the efficiency advantages of a heat pump during the milder portions of winter (which represent the majority of heating hours even in Wyoming) while maintaining the proven reliability of gas heat during extreme cold. You also get air conditioning in summer from the heat pump, making it a true year-round comfort system.
Why Dual Fuel Makes Sense in the Big Horn Basin:
- Heat pump efficiency during moderate cold saves 30-50% on heating costs
- Gas furnace backup provides reliable heat at any temperature
- Built-in air conditioning eliminates need for separate AC
- Automatic switchover requires no homeowner intervention
- Reduces gas consumption while maintaining winter reliability
- Eligible for federal tax credits and utility rebates
Rebates & Incentives
Heat pumps qualify for significant federal and state incentives that can offset 30% or more of the installation cost. The federal energy efficiency tax credit (25C) provides up to $2,000 for qualifying heat pump installations. Additional rebates may be available through your electric utility.
We help our clients identify and document all available incentives before installation so you know exactly what credits and rebates to expect. The combination of incentives, lower operating costs, and the elimination of a separate air conditioning system makes heat pumps increasingly affordable for Big Horn Basin homeowners.
Sizing & Maintenance
Sizing for Wyoming Altitude and Climate
Proper sizing of a heat pump is even more critical than sizing a furnace. An undersized heat pump will rely too heavily on backup heat during cold weather, negating its efficiency advantages. An oversized heat pump will short-cycle, reducing efficiency, comfort, and equipment life. We perform detailed heat load calculations that account for the Big Horn Basin's altitude (which affects air density and heat pump capacity), extreme low temperatures, wind exposure, and home insulation levels.
Maintenance Requirements
Heat pumps require regular maintenance to maintain their efficiency and longevity. Because they operate year-round (heating in winter, cooling in summer), they require twice-yearly service -- once before the heating season and once before the cooling season.
- Filter cleaning or replacement every 1-3 months
- Outdoor coil cleaning (spring and fall)
- Refrigerant charge verification
- Electrical connection inspection
- Defrost cycle testing
- Thermostat calibration
- Ductwork inspection for leaks
When Heat Pumps Make Sense in the Big Horn Basin
Good Candidates for Heat Pumps
- Homes with existing ductwork
- Homeowners wanting both heating and cooling
- High gas bills you want to reduce
- New construction planning phase
- Replacing an aging furnace and AC
- Interest in reducing carbon footprint
Other Options May Be Better
- No ductwork and no plans to add it
- Very low electricity rates make gas more competitive
- Home already has new high-efficiency furnace
- Primary interest is radiant floor heating

Heat Pump FAQs
Yes. Modern cold-climate heat pumps are rated to operate effectively at -15 degrees and below. While older heat pumps lost significant capacity in cold weather, today's variable-speed compressor technology maintains efficient heating even in extreme cold. For the coldest days, we recommend dual fuel systems that pair a heat pump with a gas furnace backup.
A dual fuel system combines a heat pump with a gas furnace. The heat pump handles heating efficiently down to a set temperature (typically 15-25 degrees), then the gas furnace takes over when temperatures drop further. This gives you the efficiency of a heat pump during moderate cold and the reliable BTU output of a gas furnace during extreme cold.
Heat pumps can deliver 200-300% efficiency (COP of 2-3), meaning they produce 2-3 units of heat for every unit of electricity consumed. A gas furnace maxes out at 95-98% efficiency. However, electricity costs more per unit than gas, so actual cost savings depend on local utility rates and outdoor temperatures.
A cold-climate heat pump installation in Cody typically costs $5,000-$10,000 for the outdoor unit and indoor air handler. A dual fuel system runs $8,000-$15,000. Federal tax credits and utility rebates can offset 30% or more of the cost. We provide detailed estimates that include available incentives.
Yes. A heat pump is essentially an air conditioner that can run in reverse. In summer, it removes heat from your home and expels it outdoors. In winter, it extracts heat from outdoor air and moves it indoors. One system provides both heating and cooling, eliminating the need for a separate air conditioner.
