Overview of Residential Heat Pumps: Efficient Heating & Cooling – Are you considering a heat pump for your Bozeman, MT home? Heat pumps offer an energy-efficient alternative to furnaces and air conditioners for all climates. Rather than generate heat, they use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. Living with a heat pump differs somewhat from a traditional heating system.

A modern heat pump is most efficient when the thermostat is set at a constant temperature—it saves energy if you don’t turn it down overnight. Heat pumps also blow cooler air than furnaces and run almost constantly at a low level instead of blasting heat for short periods throughout the day.

The most common type of heat pump is an air-source heat pump. It works by absorbing heat from the air and moving it from outdoors to indoors (in heating mode) or vice versa (in cooling mode). In cooling mode, air-source heat pumps work identically to ACs. The two types of appliances look similar, but heat pumps have slight differences that allow them to move heat in two directions, in and out.

In recent years, air-source heat pump technology has improved, making them a practical choice almost anywhere in the country—even in places with cold winters like Bozeman, Montana. As counterintuitive as it seems, some free heat energy is always in the air, even on frigid winter days. Modern cold-climate heat pumps can efficiently collect and move that free heat into your home.

DUCTLESS AND DUCTED AIR-SOURCE HEAT PUMPS 

In the U.S., we typically use air-source heat pumps and, most often, air-to-air heat pumps. That means they absorb and release heat from the air (rather than water or earth) and deliver heating or cooling to your home through a forced-air system. Among air-to-air heat pumps, two types are most common in residential homes: ducted air-source heat pumps and ductless (mini-split) air-source heat pumps.

DUCTED AIR-SOURCE HEAT PUMP:

A ducted air-source heat pump looks and acts like a central AC. There is an outdoor and an indoor unit. Both units have aluminum fins and coils to release or collect heat, connected by a refrigerant line filled with fluid that transports heat between the two. The outdoor unit also has a compressor, which compresses and circulates the refrigerant. It hooks up to ducts inside your home, and a blower circulates the warm or cool air through those ducts and out of air vents placed around your house.  

DUCTLESS (MINI-SPLIT) AIR-SOURCE HEAT PUMP:

A ductless mini-split system heats and cools air like a ducted model but doesn’t rely on ductwork to move warm or cool air through your house. Instead, the outdoor unit connects to one or more indoor air handlers, or “heads,” installed throughout your home. It’s a common, straightforward way to add a heat pump to a home or section of a house that doesn’t have ducts. 

Typically, air-handler heads are placed high on a wall, but if you don’t like the look or don’t have the space, they can sometimes be placed inside the ceiling or floor. Mini-splits are also more energy-efficient than ducted heat pumps because they avoid energy losses typically associated with ductwork.  

DO YOU NEED A BACKUP HEATING SYSTEM?

You can use a heat pump as your home’s sole heating and cooling appliance or combine a heat pump with an existing heating system. Many homes with existing ductwork for forced-air HVAC systems can be adapted to heat pumps. Ductless heat pump systems, called mini-splits, can provide heating and cooling in a home without ducts or add climate control to rooms the primary system doesn’t reach.

A backup heating system shouldn’t be necessary if it has the right heat pump and system design for your home and regional climate. However, a backup system can be the most cost-effective way to keep your home comfortable in cold temperatures. It could be a hybrid setup rather than a system with a backup. 

You’ll use the heat pump most of the time (including the summer, when it provides all your cooling) and the backup system only on the coldest days when the heat pump can’t keep up. A contractor can set up the system to switch automatically at a specific outdoor temperature.

Hybrid systems still save a ton of energy and carbon emissions compared with most other setups and can offer some peace of mind in colder climates.

RESIDENTIAL HEAT PUMPS: REGULAR MAINTENANCE

Heat pumps should receive regular maintenance for optimal performance. Once a year, A professional contractor should clean and flush the coils, drain the pan and drainage system, and vacuum the blower compartments. The contractor should also ensure that the system is correctly charged with refrigerant, that there are no leaks, and that all mechanical components are working as they should. 

Homeowners can also do regular maintenance such as cleaning grilles and filters monthly, clearing debris and dirt from condenser coils, and checking for blockages in the drainpipe. Follow the manufacturer’s directions for changing the filter. Generally, the thicker a disposable filter, the less frequently it needs to be changed. 

PROPER SIZING: WHY YOU NEED A PROFESSIONAL HVAC CONTRACTOR  

As with most heating and cooling systems, hiring a professional contractor to design and install a new heat pump system is wise. The margin for error with heat pumps is smaller than with traditional heating systems, making proper sizing critical.  

Efficiency and Performance:  If a heat pump is improperly sized, it may struggle to provide sufficient heating or cooling capacity for your home. An undersized heat pump will work continuously and may not reach the desired indoor temperature, leading to discomfort. Conversely, an oversized heat pump may cycle on and off frequently, reducing efficiency and potentially causing wear and tear on the system.

Energy Efficiency: Properly sized heat pumps are more energy-efficient. An accurately sized unit closely matches your home’s heating and cooling needs, leading to optimal efficiency and lower energy bills. An oversized heat pump will consume more energy, as it frequently starts and stops, while an undersized one will run continuously, consuming excess electricity. Efficient operation is one of the primary advantages of heat pumps, and improper sizing can significantly compromise this efficiency.

Comfort and Temperature Control: A well-sized heat pump ensures consistent indoor comfort. It can maintain a stable indoor temperature, avoiding temperature swings and cold or hot spots. This comfort level is challenging with an improperly sized system, resulting in uneven heating or cooling and discomfort for occupants.

Longevity and Reliability: Proper sizing extends the lifespan of your heat pump. When a heat pump is appropriately sized, it operates within its design parameters, reducing wear and tear on its components. This can lead to fewer breakdowns and repairs, ultimately increasing the system’s longevity and reliability.

Noise Levels: Oversized heat pumps can be noisier because they cycle on and off frequently. This can be disruptive and annoying for homeowners. An adequately sized heat pump operates quietly and smoothly, enhancing your indoor environment.

Cost Savings: Properly sizing a heat pump saves you money in the long run. While the initial installation cost may vary depending on sizing needs, an accurately sized system will provide better efficiency and performance, leading to lower utility bills and potentially offsetting the initial investment.

In summary, an experienced and knowledgeable HVAC contractor ensures your home’s proper heat pump sizing. They will calculate load, considering your home’s size, insulation, windows, climate, and other variables to determine the ideal heat pump size. This ensures your chosen unit will effectively and efficiently meet your heating and cooling needs, resulting in a comfortable, energy-efficient, and reliable system for all seasons.
