Heat Pumps

Heat pumps are versatile HVAC systems that transfer heat between indoor and outdoor environments to efficiently regulate temperatures in residential and commercial spaces. By extracting heat from the air, water, or ground, they can warm interiors during colder months and provide cooling in hotter weather. Operating on electricity, heat pumps offer energy-efficient heating and cooling solutions, particularly in moderate climates. Their ability to both heat and cool spaces with a single system makes them popular choices for homeowners seeking year-round comfort. As sustainability becomes a priority, heat pumps play a crucial role in reducing carbon emissions and promoting eco-friendly heating and cooling practices.

Heat pumps use similar technology to air conditioners and refrigerators, and they have a reversing valve that allows them to heat and cool.
 
Cooling mode:
In cooling mode, the heat pump absorbs heat from inside the home and releases it outside. This works similarly to an air conditioner, which uses a refrigerant to absorb heat from the air and transfer it outside. The refrigerant is pressurized, which raises the temperature.
Heating mode:

In heating mode, the heat pump absorbs heat from outside the home, such as the air or ground, and releases it inside. The heat pump can even extract heat from cold air.

Heat pumps can use different sources of heat, including:
  • Air: The outdoor unit of the heat pump pulls heat from the air outside, even when it’s cold.
  • Geothermal energy: Heat pumps can extract heat stored in the ground.
  • Water: Heat pumps can extract heat from water sources, such as wells or lakes. In an open-loop system, water is pumped out of the source, the heat is extracted, and the water is then returned to the source.

Heat Pump F.A.Q.

Frequently Asked Questions

A heat pump is a single HVAC system that provides both heating and cooling for your home by moving heat rather than generating it through combustion. It uses refrigerant and a reversing valve to change direction between modes. In cooling mode it works exactly like a central air conditioner, absorbing heat from inside the home and releasing it outdoors. In heating mode it reverses the process, extracting heat energy from the outdoor air and transferring it indoors.

Even cold outdoor air contains usable heat energy, which is what makes heat pumps efficient at temperatures well below freezing. Because a heat pump moves heat instead of burning fuel, it can deliver two to four units of heating or cooling energy for every one unit of electricity it uses, making it significantly more efficient than electric resistance heating.

This is the most important question for Jackson County homeowners considering a heat pump, and the answer depends heavily on which type of system you choose. Standard air-source heat pumps lose efficiency and heating capacity as outdoor temperatures drop below 25 to 30°F, which can be a real limitation during Michigan winters.

However, modern cold-climate heat pumps, sometimes called hyper-heat models, are specifically engineered to maintain strong heating output at outdoor temperatures as low as -13°F to -22°F, well below anything Jackson County typically sees. Many Michigan homeowners use a cold-climate heat pump as their primary heating source and pair it with a gas furnace backup for only the most extreme cold stretches, a setup called a dual-fuel system.

Aspen One Hour Heating & Air Conditioning can help you evaluate whether a heat pump alone or a dual-fuel configuration makes the most sense for your home and how you use it.

Heat pumps offer a compelling combination of efficiency, versatility, and lower operating costs. Because they move heat rather than burning fuel, they can reduce heating energy consumption by 50% or more compared to electric resistance heating, and often compare favorably to gas furnaces in moderate temperatures.

A single heat pump handles both heating and cooling, which means one system, one maintenance schedule, and one service contractor for year-round comfort. Heat pumps produce no on-site combustion, which eliminates carbon monoxide risk from the heating equipment and reduces your home’s carbon footprint. For homes without existing ductwork, ductless mini-split heat pumps offer the same benefits without the need for any major structural work.

Yes, Aspen One Hour Heating & Air Conditioning provides heat pump installation, repair, and maintenance throughout Jackson County and surrounding areas including Ingham, Eaton, Calhoun, Hillsdale, Lenawee, and Washtenaw counties.

The team is experienced with air-source heat pumps, ductless mini-split heat pump systems, and dual-fuel configurations, and can help you determine which setup makes the most sense for your home, budget, and how you heat and cool.

Heat pump efficiency is measured by two ratings depending on the season. For cooling, efficiency is measured by SEER (Seasonal Energy Efficiency Ratio), with higher numbers indicating greater efficiency. For heating, it is measured by HSPF (Heating Seasonal Performance Factor). Modern heat pumps typically carry SEER ratings of 15 to 20 or higher and HSPF ratings of 8 to 10 or above. In practical terms, heat pumps deliver roughly 2 to 4 units of heating or cooling energy for every unit of electricity consumed, meaning a heat pump with a COP of 3 is 300% efficient.

That efficiency advantage is most significant in the mild shoulder seasons of spring and fall, and modern cold-climate models maintain strong efficiency even in colder conditions. Compared to a standard electric furnace or baseboard heaters, a heat pump can cut heating energy use dramatically.

Heat pumps should be professionally serviced twice a year since they handle both heating and cooling and run year-round, unlike a furnace or AC that each have a dedicated season. Ideally the system should be serviced once in spring before the cooling season and once in fall before the heating season.

Each service visit includes checking refrigerant levels, cleaning the indoor and outdoor coils, inspecting and lubricating the blower motor, testing the reversing valve, checking the defrost controls, inspecting electrical connections, and verifying the system is operating efficiently in both modes. Homeowners can contribute by changing or cleaning the air filter every one to three months and keeping the outdoor unit clear of debris, leaves, and ice buildup. 

A dual-fuel system pairs an air-source heat pump with a gas furnace as a backup heat source. The heat pump handles the heating load efficiently during mild to moderately cold weather, which covers the bulk of Michigan’s heating season. When outdoor temperatures drop to a set switchover point, typically around 25 to 35°F depending on the system setup, the gas furnace automatically takes over since it becomes more cost-effective to burn gas than to run the heat pump at reduced efficiency in extreme cold.

The result is the best of both worlds: the efficiency of a heat pump for most of the year and the reliable power of a gas furnace for the coldest stretches. For Jackson County homeowners with existing ductwork and a gas line who are looking to reduce energy costs without sacrificing heating reliability, a dual-fuel system is one of the smartest HVAC upgrades available.

Common heat pump issues include the system blowing cool air in heating mode, which is often caused by a low refrigerant charge, a failing reversing valve, or a defrost cycle that isn’t functioning properly. Ice building up on the outdoor unit beyond normal defrost cycles can indicate a refrigerant issue or an airflow problem. A heat pump that runs constantly without reaching the set temperature may be undersized for the space or losing efficiency due to dirty coils or a clogged filter.

Unusual noises like grinding, squealing, or rattling often point to a failing motor bearing or loose component. Short cycling, where the system turns on and off frequently, can stem from an oversized system, refrigerant issues, or electrical faults. If your heat pump is blowing cold air in heating mode on a day that isn’t extremely cold, calling Aspen One Hour Heating & Air Conditioning at (517) 879-2049 for a diagnosis is the right move.
