Definition And Function
Heat pump air handlers are responsible for circulating heated or cooled air from the indoor unit of a heat pump system throughout your home.
Heat pumps do not create heat, but instead use refrigerant to transfer it in and out of the house depending on whether you need cooling or heating.
A typical air handler may contain two main systems: an evaporator coil which helps absorb heat during the summer to provide cooling functions, and a condenser coil which helps expel excess heat in the winter for heating operations.
Both coils work together with a fan inside an enclosure to control airflow and regulate temperatures indoors throughout the year.
Components Of A Heat Pump Air Handler
Blower:
The blower in a heat pump air handler moves or circulates either heated or cooled air throughout the home. Air is moved through ducts and over evaporator and condenser coils, which assists in the exchange of warm and cold temperatures.
Evaporator Coil & Condenser Coil:
Heat pumps require two sets of coils to work properly. The evaporator coil located inside your home near the indoor unit, and an outdoor condenser coil is connected to the outdoor unit.
Refrigerant passes from the outside into these coils via copper piping to help transfer hot or cold energy indoors according to temperature preferences set by a thermostat (heating mode is equal to heat exchange occurs between colder outside air and warmer refrigerant).
Fan Motor Assembly/Fan Blades:
Inside an air handler’s fan motor assembly are fan blades that draw in either cooler or warmer air, depending on season settings selected at a thermostat control panel.
These blades then spin around inside enclosed hub-like units (air handlers) to move this air through ductwork for circulation throughout corresponding areas of homes/businesses at preset speeds.
Filter Grille & Cabinet:
Inside each cabinet sits an emissions filter designed to prevent larger particles like dust from entering back into living spaces when heated airflow runs out for distribution outdoors during summer months as part of conditioning cycles.
It also trap mold spores common all year long among other allergens associated with high-efficiency HVAC systems. This helps improve quality since filtered intake sources don’t mix directly with conditioned space within buildings but rather remain trapped so that only clean airstreams pass along interior cfm ratios meant exclusively for personal enjoyment uninterruptedly.
Different Types Of Heat Pump Air Handlers
There are a variety of heat pump air handler models and configurations available.
Variable-Speed Air Handlers
Variable-speed air handlers use compressors that vary their speeds depending on the temperature of the room and your comfort preferences. A variable speed compressor is more efficient than a traditional single speed HVAC system, as it runs at lower capacities when needed so there’s less energy waste.
These units typically run at lower increments to maintain constant airflow in your home and increased efficiency. This ensures maximum comfort with minimal drafts since the air handler will try to keep an even temperature throughout your space
.
Plus, because these systems can detect changes in temperatures or indoor levels of humidity, they’re able to adjust accordingly for further cost savings on monthly energy bills.
Unlike typical fixed-speed motors that may stay running longer than necessary consuming more electricity and costing you more money, a variable-speed motor runs only when absolutely necessary which makes them much more energy efficient overall.
Two-Stage Heat Pump Air Handlers
Two-stage heat pumps are a great choice for controlling temperatures in the home, as they offer more flexibility than single-stage systems. This type of air handler operates differently than other versions and is typically associated with efficient matched systems.
Two-stage cooling provides two varying levels of operation to match the level of comfort desired by the homeowner and provides both noise reduction and control over humidity better than traditional single-stage units.
Carrier’s 2-Stage Heat Pumps have become well known over time, as customers recognize their commitment to making reliable and energy-efficient products that can cool or heat any size space efficiently.
The two variable speeds these models use to maximize efficiency year-round while reducing power consumption by up to 1/3 compared to older models running on a constant speed set point.
Variable speed motors change automatically from low (energy saving) or high capacity (stronger performance) based upon indoor temperature. Ttactics used such as zoning is used when available, allowing homeowners precise control over your HVAC system at all times.
It results superior comfort levels, and less electricity consumed.
Matched Systems
A matched system is a vital part of the heat pump air handler configuration. The components must be properly sized and paired to maximize energy efficiency and performance while preventing inefficiency or equipment failure.
A matched system is composed of an outdoor condenser, indoor blowers/air handlers with coils and fans, optional electric heat strips, thermostats for temperature control, and proper ductwork sizing.
The most important parts to match correctly are the sizer class ratings between the outdoor unit’s cooling capacity as rated by a Seasonal Energy Efficiency Ratio (SEER) rating that expresses the unit’s efficiency at peak conditions and the inside coefficient of performance (COP), which measures how much energy it takes to generate one ton of air-conditioned space inside your home versus outside on average over multiple seasons.
If these numbers do not match up with guidelines set forth by manufacturers, likely there will be subpar heating operations like short cycling or wasted energy due to long cycle times trying to get one-stage or two stage systems up to competency levels that won’t happen. Because they can’t reach correct temperature ranges as designed on their specification sheets regarding actual BTU output per hour required given conditions.
Choosing The Right Heat Pump Air Handler
When choosing a heat pump air handler, it’s important to take into account factors such as the size of your home, energy efficiency ratings, and how well the system matches with other HVAC components.
Building size and layout:
Careful consideration should be given to the square footage of the space, as well as the number of rooms/occupants that will use it. An oversized system may not run efficiently; conversely, an undersized unit can’t provide adequate heating or cooling.
Usage patterns:
Heating and cooling systems are engineered with specific usage in mind (daily heating vs temperature swings). This will inform your choice of system type (e.g., air-to-air vs water source), runtime expectations, performance needs, etc.
Compatibility with other equipment/systems:
Consider if a new system might require reworking existing ductwork within the building or could new “smart” features improve upon existing indoor airflow distribution levels.
Be sure any planned changes don’t compromise compatibility between old components and newer designs, malfunctions may result otherwise.
Finding The Right Size For Your Home
Choosing the right size heat pump for your home is crucial for maximizing energy efficiency and saving money over time.
An HVAC professional on-site is necessary to accurately determine the correct size of heat pump needed, as opposed to relying solely on online sizing guides or calculations that may not take into account important factors like climate zone and square footage.
If a heat pump unit is too large for the area it will be heating and cooling, it can lead to longer cycles that don’t effectively remove humidity from the air, resulting in decreased comfort levels inside the home.
On the other hand, if a unit is too small for the area being heated or cooled, it will cause shorter cycles that require much more frequent activation in order to maintain temperature level throughout your house.
This leads to increased operational costs due to potential cycling issues with equipment components such as compressors and fans. Thus leading to an increased likelihood of repair needs.
It’s also worth noting that undersize systems are often unable to provide adequate heating or cooling when multiple rooms need attention simultaneously or during periods with extreme hot/cold temperatures outside.
Energy Efficiency Ratings
Energy efficiency ratings provide a measure of how much energy is consumed to cool or heat a space.
The most widely accepted ratings used for Heat Pump Air Handlers are the Seasonal Energy Efficiency Rating (SEER) which measures cooling-mode efficiency, and Heating Season Performance Factor (HSPF), which measures heating-mode efficiency.
Other important rating are Annual Fuel Utilization Efficiency (AFUE), which indicates an overall annual operating costs analysis; and ENERGY STAR certification, which identifies high-efficiency systems that meet certain criteria determined by the EPA.
Ratings such as SEER indicate the system’s energy output during cooling mode, so higher ratings mean greater energy savings potential per unit of electricity used.
When purchasing a HVAC system with an air handler component, it is wise to review all applicable rating labels before deciding on a purchase in order to ensure you get both effective performance and cost savings from your new air handler system.
Wiring A Heat Pump Air Handler
It is important to understand the electrical requirements, diagrams and procedures to properly wire a heat pump air handler.
Electrical Requirements
Heat pump air handlers require an adequate electrical supply to power the system, making it essential for each part to be correctly wired in order for the unit to operate safely and efficiently.
Most standard air source heat pumps running on an outdoor compressor require a 240-volt, 30-amp circuit with specific conductor sizes according to voltage drop and fault current calculations from the point of service at the meter base location.
In addition, 5 wires are required for internal wiring, black (line), red (secondary line), white (neutral), yellow or blue (common control wire) and green or bare copper (ground).
Alternatively, resistance heaters require a dedicated circuit with different kW sizing depending on their wattage. Thus proper breaker size is important so they can function effectively without tripping the fuse box in case of overloading.
The thermostat should also be wired properly as it connects all components within your heating/cooling system, at least 8 color-coded wires have to connect accordingly between thermostat terminals and HVAC equipment terminals/boards.
Not paying attention to these requirements could lead to serious risks such as fire hazard caused by low voltage that causes overheating of some parts due inappropriate installation procedures not being followed correctly.
Wiring Diagrams
Wiring diagrams for heat pump air handlers are incredibly important documents that should be followed to the letter in order to ensure proper installation and operation of your HVAC system.
Without an accurate wiring diagram, using incorrect wires or connections could cause permanent damage to the system and even dangerous electrical shocks.
For instance, when wiring a Trane XL824 Connected Control TCONT824 it is critical for homeowners to follow instructions for their specific model. This includes details on properly connecting incoming power lines as well as output devices such as fans and blowers. All of these need to be wired correctly in order for optimal performance from your unit.
How To Wire A Heat Pump Air Handler
- To properly wire a heat pump air handler, an understanding of the system components and wiring diagrams is essential. The thermostat commonly requires at least 8 electrical connections to work correctly in the heat pump system. These include connecting 18 gauge wires between the thermostat and air handler unit along with signals from outdoor units or electric heat strips for control purposes.
- Certified, UL-listed low volt wire must be pulled from the outdoor heat pump to the indoor air handler when wiring a heat strip and/or multiple electric motors for variable speed blower features (if applicable). This should also be run through conduit tubing for additional protection if needed using a three conductor set up size 14 AWG copper durable stranded core type NM-B cable or GFCI grounding circuits protecting all connected devices, fans, powers sources etc., as outlined in local building codes requirements. It is important that all wired conduits penetrations within wall assemblies are sealed against moisture intrusion according to good construction practices and safety regulations before installation begins.
- Ductless mini split systems with one outdoor unit can connect up to four indoor handlers but require specific sizing guidelines regarding capacity requirements among other factors like makeup & outside air changes as well as distance between each sectional componentry. Such considerations will need to be taken into account during design phase of such installations prior any actual works being commissioned on site.
Compatibility Of Heat Pump Air Handler With Other HVAC Systems
When choosing a heat pump air handler, it is important to consider compatibility with other HVAC systems.
If the air handler is not compatible with existing central AC systems or thermostats, it can result in reduced efficiency and increased energy costs.
To avoid mismatches, look for an air handler that is compatible with ENERGY STAR-rated heating and cooling units from reputable manufacturers who offer warranties on their products when installed as part of a matched system.
Ensure that any additional components such as blowers, motors, coils and filters are also compatible before installation begins.
Replacing A Heat Pump Air Handler
Replacing your existing heat pump air handler with an energy-efficient option can dramatically reduce the amount of electricity used to maintain comfort and improve the overall efficiency of your HVAC system.
Reasons To Upgrade
Upgrading an outdated or faulty heat pump air handler can be a great way to reduce energy bills, improve efficiency and comfort levels. While it is possible to replace a heat pump without replacing the air handler, there are certain compatibility considerations that must be taken into account in order for the new unit to work appropriately with the existing system.
Remember to consider both cost of equipment used for replacement as well as additional costs associated with any necessary ductwork modifications before beginning installation.
Upgrading with SEER-certified models utilizing newer technologies such as variable-speed motors can make all the difference in heating and cooling your home over inefficient furnaces or conventional heat pumps which generally run on fixed speeds regardless of needs providing long term savings due its increased efficiency during milder weather cycles while reducing energy usage overall.
Cost Savings
Installing a heat pump air handler can yield significant financial savings over the long term. Heat pumps are much more energy efficient than traditional heating and cooling solutions, allowing for up to 50% less electricity usage in some cases.
On top of that, there is also the potential for federal tax credits on qualifying models. For example, homeowners may be able to claim a credit worth 10-30% of the cost of the system on their taxes when they install an efficient system.
Additionally, many states offer rebates that incentivize buyers to choose energy-efficient solutions over traditional HVAC systems which further help reduce costs associated with installation and operations even further.
Energy Efficiency
Heat pump air handlers offer higher energy efficiency than traditional air-source heat pumps, thanks to their combination of components.
A high SEER rating indicates that your unit is able to transfer more cooling power per kilowatt hour while a high HSPF rating tells you how efficiently it can deliver heated air in colder seasons.
When purchasing a new system, it’s important to look for these two factors as they will determine both how much electricity you use as well as potential savings on monthly bills.
Improperly installed or maintained systems can reduce the overall system’s energy efficiency so professional installation and regular maintenance are essential if you want an efficient functioning unit over time.
Improved Comfort
Heat pump air handlers can improve comfort in your home or office by providing consistent, efficient heating and cooling that is tailored to the needs of each zone.
Heat pumps are paired with an air handler to create a more environmental friendly HVAC system as they rely on electricity rather than gas combustion. This key feature also increases energy efficiency and thus reduces energy bills significantly throughout the year.
Additionally, due to their ability to work in tandem with zoning systems, heat pump air handlers can use sensors distributed around the premises to read temperature data from different zones and then adjust compressor speeds accordingly.
This not only provides continuous comfort without wasting money but it also ensures improved indoor air quality for a healthier living/working environment since pollutants are properly removed from circulation.
Cost Considerations
When considering the cost of a new heat pump air handler, there are several factors to take into account. Professional installation costs may range from $3,950 to $14,350 for 2-5 ton systems and up to $22,400 for a complete central heat pump and air handler unit.
Additionally, it is important that professionals perform an adequate load calculation in order to determine the size needed in each space. If the system is too small it will not be able to operate efficiently or adequately cool/heat your home and an oversized system can result in energy waste as well as frequent on-and-off cycling which could cause premature wear on components or require unnecessary repair.
Modifications made to ductwork such as repairs might increase install expenses. Dutdoor units need additional clearance while certain models may require special locations due to how they are designed. Wiring upgrades may also factor into total costs depending on the current electrical scale and design.

FAQs:
What is a heat pump air handler?
A heat pump air handler is an HVAC unit that combines both heating and cooling functions in a single, compact package. It pulls in and circulates warm or cool air throughout your home or business while providing efficient energy savings compared to traditional separate systems.
How does a heat pump work?
Heat pumps move thermal energy from one place to another using refrigerant fluid and fans. In the case of a furnace, during cold months, it would absorb indoor warmth and transport it into outdoor spaces. In hot weather, it reverses this process by drawing outside chilliness indoors while expelling any built-up humidity too.
Are there advantages of using a heat pump system over other types of HVAC units?
Yes! Heat pumps require less maintenance than typical furnaces or ACs as they are all-in-one devices that replace up to three units traditionally used for temperature regulation indoors, meaning fewer components need regular service (and therefore fewer potential breakdowns). Additionally, they generally have higher SEER ratings (Seasonal Energy Efficiency Ratio) than central air conditioning systems meaning these operate at higher levels of efficiency & could save you money on utility bills too.
How can I ensure my new Heat Pump Air Handler works correctly once installed?
Post-installation testing should always be done before use. Taking into consideration factors such as fan speed settings, thermostat accuracy/operation control parameters & outdoor condenser unit performance checks etc. A qualified technician experienced with Heat Pump installations should be able to carry out post inspections when necessary ensuring the device remains operating within its predefined parameters effectively for minimized wear & tear down the line.
