In , heat pumps passed gas furnaces in sales for North America. Heat pumps are becoming increasingly popular as heating and cooling solutions for residential and commercial installations. It is vital for you, as an HVAC contractor, to have an excellent understanding of how they work and the proper methods to install them. This article will provide essential information to increase your business and profit from the electric heat pump installation boom.
What Is a Heat Pump?
A traditional furnace burns either fuel oil or gas to generate heat. An electric furnace converts electricity to heat. A heat pump functions quite differently because it doesn't generate heat. It moves it from an outside source into a target area. Heat pumps are considerably more efficient than conventional systems. They can deliver up to four times more heat energy than the electrical energy they consume to produce it.
Types of Heat Pumps
The types of heat pumps are differentiated by their heat source. The primary types of pumps are:
- Ground source. For the system to work, the ground has to store heat generated by the sun, like the hot pavement or asphalt that can burn your feet on a summer day. If the earth absorbs more heat than the pump draws off, a heat pump will have a sustainable and reliable heat source.
- Air source. For this type of heat pump to work, the outside air must maintain a temperature above a particular baseline. The viability of this type of heat pump will depend on the climate of your service area.
- Water source. If your customers can access a lake or other body of stable water through weather cycles, you can utilize it as a sustainable heat source.
Energy Efficiency and Cost Savings of Heat Pumps
As of Jan. , the Department of Energy (DOE) increased the Seasonal Energy Efficiency Ratio (SEER) required for heat pumps from 14 to 15 SEER. It also specified test procedures and new metrics to familiarize yourself with.
Heat Pump Efficiency
While air conditioners and heat pumps function similarly for cooling, you must combine air conditioners with heating systems for complete climate control. A heat pump, however, can operate in both capacities, providing heat and cooling as temperatures fluctuate.
This dual functionality makes heat pumps more efficient and cost-effective than a hybrid system. Leading heat pump suppliers sell units with SEER ratings higher than the required 15 SEER. These range from 20 to 33.1. Since higher SEER ratings come at a higher cost, you can choose the unit that best meets your customer's requirements and budget
Heat Pump Pricing
The cost of commercial heat pumps can vary significantly based on several factors, including the size of the system, brand, efficiency ratings, installation requirements, and additional features.
On average, commercial heat pumps can range from $5,000 to $30,000 or more. However, this price range is quite broad and can be influenced by several key factors:
- System Size
- Efficiency Ratings
- Brand and Quality
- Installation Requirements
- Additional Features
- Geographical Location
One cheap alternative is ductless mini splits that cool limited zones in a home. These heat pump systems feature small units connected to a unit outside. Mini-splits mitigate the considerable heat loss that can occur from ductwork and are easier to install. Expect to charge between $1,500 and $5,000 for the units and installation.
Owners of commercial buildings and homes with extensive square footage might request a gas-fired heat pump. These units are less efficient than other types of heat pumps and have a more negative environmental impact. However, they can regulate the temperature in multiple zones and large spaces.
Heat Pump Installation and Maintenance
You will deal with several issues when installing a heat pump. You must size it correctly, meet the electrical requirements and prepare for maintenance and troubleshooting.
Sizing a Heat Pump
Many factors go into sizing a heat pump. Your first consideration is the size of the space. The larger the area, the bigger the pump requirements. However, the same size space in different climate zones will require another size pump. One method you can use for sizing is matching the capacity of an existing air conditioner.
If no functioning air conditioner is present or the system cools insufficiently, you can use the square footage and the efficiency of an existing furnace to determine the required BTU output. The colder your climate, the more BTUs you will need. Your calculations will be similar to those an HVAC contractor performs before installing a conventional furnace. You can find a calculator and climate information here to speed up your process.
Electrical Requirements
You can read the regulations for electrical systems for heat pumps in Article 440 of the National Electrical Code ( NEC). An air source heat pump requires at least 240 volts and a 30-amp circuit breaker. Larger systems may need a dedicated power supply with a circuit breaker. Depending on the size of your circuit breaker, you may be using a ten-gauge or eight-gauge wire. Since ground-sourced units don't use fans, their electrical needs are more limited. Existing wiring with 200 amp service may be enough. Water source pumps also typically have lower electrical demand and may not require significant electrical work.
You may find that customers interested in heat pumps are also interested in electric vehicles (EVs). The extra wiring and capacity you install for an EV can provide a ready-made path to a heat pump.
Regular Maintenance and Troubleshooting
Regular maintenance of heat pump systems involves cleaning and replacing worn components &#; preferably before a breakdown. You can handle this expeditiously with a long-term service contract attached to your warranty. You will not only ensure your customers remain satisfied and likely to recommend your work, but you will also help them avoid the cost of replacing a system.
Common Issues with Heat Pumps
As with any other type of system, heat pumps can develop problems. Some common causes of malfunctions are :
- Refrigerant leaks.
- Dirty air filters.
- The outside coils need cleaning.
- The thermostat needs recalibration.
- The thermostat isn't communicating correctly with the system.
These problems are easily addressed and may be as simple to correct as hosing off an outdoor coil. Most of these occurrences can be prevented by regularly scheduled maintenance.
However, if your customer detects a strange odor, it could be a clue to a serious electrical issue. The smell of something burning could be coming from the wiring. A fishy scent can come from wiring or an overheated motor. Make it clear that in either case, they should call you.
Strange sounds can mean that the bearings in the motor are dirty. You will want to check them out before the motor burns out entirely.
A customer's most significant problems will arise from an improperly chosen unit. You can prevent that issue by providing the most effective products and sizing.

Are you searching for an energy-efficient way to heat and cool your home? Look no further than a heat pump. Heat pumps are incredibly efficient, using less energy than traditional heating and cooling systems. A heat pump can easily warm or cool your house and save you money. They also give you control over the temperature inside of your home, so you can stay comfortable indoors all year. Before purchasing a new heat pump for your residence, you should consider several factors outlined below.
1. Size
A heat pump that&#;s too small can only meet a fraction of your needs. If it can&#;t keep up, you may not enjoy a comfortable environment in your house. On the other hand, a heat pump that&#;s too large can lead to increased energy bills, as it will use more power than necessary.
To choose the right size heat pump, you&#;ll need to know the size of your home in square feet. It&#;s also important to consider the size and number of windows in each room and how much insulation is in the walls and roof. That way, you can get the right-sized unit for your property.
2. Efficiency
You should always look for a high-efficiency rating when purchasing a heat pump. This is measured in SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor). The higher your heat pump&#;s rating, the more energy-efficient and cost-effective it will be.
It&#;s also critical to consider the type of compressor utilized in the system for successful operation. Some models are more efficient than others. Additionally, look for a heat pump with variable-speed technology, as this can increase energy efficiency and help you save money on your energy bills.

Not all heat pumps are created equal, so you should compare different models to find the best fit for your needs. Look for features like a built-in thermostat, programmable settings, and timers to help you control your energy usage and save money. You may also consider intelligent defrosting, air filtration systems, and humidity control.
These additional features can further increase the efficiency of your heat pump system while also providing extra comfort in your home. Other features include noise level, warranty coverage, and installation costs. Make sure to research before purchasing to choose the right heat pump for your needs.
4. Design
Different heat pumps are designed for different applications. Some are designed to be used outdoors, while others can be installed indoors. If you have the space and prefer a smaller outdoor unit, then an indoor heat pump may be more suitable for your needs.
It&#;s also important to consider the aesthetics of the heat pump you choose. Some models come in various colors and styles that can easily blend into your home&#;s décor. On the other hand, some models are purposely designed to stand out and make a statement. The heat pump design should suit your needs and personal style so that it looks great in your house.
5. Cost
The price of a heat pump can vary greatly depending on its size, features, and design. It&#;s important to set a budget and shop around for the best deal. If you&#;re buying an energy-efficient model, it may be more expensive upfront but could save you money in the long run.
It&#;s also worth considering installation costs, as some heat pumps require professional help while others are relatively simple. Compare different models and get quotes from various suppliers to find the best option for your budget. That way, you can stay within your budget and get the perfect heat pump for your home.
6. Brand
The brand of a heat pump matters, as some are more reliable than others. Choose a brand that has a good reputation and offers quality products. Consider how long they&#;ve been operating in the industry and whether they offer any warranties on their products. That can give you peace of mind when making your purchase.
Remember to also read customer reviews and ratings to get an idea about the overall quality of a product. This can help you make an informed decision.
7. Environmental Friendliness
If you&#;re an environmental enthusiast, then you may want to pay special attention to the environmental friendliness of your heat pump. Look for models with an Energy Star rating, and consider advanced features such as Smart Grid technology. This can help you save money on your energy bills while reducing your environmental impact.
Look for heat pumps from sustainable materials such as recycled plastic, bamboo, or other renewable resources. By making eco-friendly choices when purchasing a new heat pump, you can contribute to a greener future for everyone.
