Hydronic air handler prices

Hydronic air handler prices are $1,000 to $1,600 on average, depending on the size and brand. A hydronic air handler connects to a condensing gas boiler or tankless water heater, redirecting the hot water through its own coil to heat the air before blowing it through the ductwork.

Variable-speed air handler cost

A variable-speed air handler costs $1,400 to $2,500 on average. Variable-speed motors are more energy-efficient because they can run at any capacity and adjust automatically to meet the home's current heating or cooling needs. Single-speed motors only run at full capacity.

Air handler price list by brand

Most brands offer air handlers in sizes ranging from 1.5 to 5 tons with a 10-year parts warranty:

Cost to replace heat pump and air handler

The cost to install a heat pump is $3,800 to $8,200 on average, depending on the size, SEER efficiency rating, and brand. A new heat pump installation typically includes an indoor air handler.

Cost to replace condenser and air handler

AC condenser replacement costs $1,200 to $4,200 on average. Replacing the air handler and condenser at the same time is recommended because the two components must match in tonnage and SEER rating.

Air handling unit replacement part costs

Average AC repairs cost $75 to $150 per hour, plus parts. Replacing parts within the air handler may be more cost-efficient:

Air handling unit replacement part costs
Part Average replacement cost*
Blower fan / motor $200 – $900
Evaporator coil $400 – $2,400
Coil cleaning $100 – $400

*Including parts and labor.

  • Blower motor replacement costs $300 to $900 on average. The blower motor pushes conditioned air from the air handler through the ductwork.
  • AC coil replacement costs $650 to $2,400 on average. The air handler evaporator coil extracts heat from the indoor air.
  • Air handler coil cleaning costs $100 to $400 on average. AC coils should be cleaned at least once per year. Coil cleaning improves air quality, increases the AC unit's lifespan, and reduces energy costs.

Frequently asked questions

What size air handler do I need?

The air handler must match the size of the condenser unit in tons for optimal performance. To find your condenser unit's size, look for the two-digit number within the model number on the label. Divide that number by 12 to get the tonnage.

How does an air handler work?

The air handler regulates the circulation of air in the home and consists of a blower motor, evaporator coil, and air filter. The blower motor moves air across the evaporator coil for heating or cooling then distributes it throughout the home via the ductwork.

The air handler creates a continuous cycle, drawing air in from the home through the return vents and delivering conditioned air back to each room via the supply vents.

Where is an air handler located?

The air handler is located indoors, typically in the attic, crawl space, basement, or a dedicated closet.

How long do air handlers last?

An air handler lasts 12 to 15 years if properly maintained. The air handler's lifespan depends on the quality, environment usage, and whether it is cleaned and serviced regularly. HVAC systems in areas with extreme temperatures typically have the shortest lifespan.

An AC tune-up costs $70 to $200, extends the air handler's life, and often prevents the need for costly repairs.

What’s the difference between a forced-air and hydro HVAC system?

A forced-air furnace burns fuel to heat the air and uses a blower to push warm air through the ducts. A hydronic HVAC system heats water in a boiler and distributes the hot water to radiators, baseboards, or radiant floor tubing throughout the home.

What’s the difference between an air conditioner and an air handler?

The air handler is the indoor component of a split-system air conditioner or heat pump. The outdoor AC condenser unit sends refrigerant to the evaporator coil in the air handler, where heat is removed from the air and the cooled air is blown into the ducts.

What’s the difference between air handler and furnace?

A furnace burns fuel to produce its own heat and uses a blower motor to distribute the air. An air handler connects to a heat pump or AC condenser and distributes air that is heated or cooled by the system. Some furnaces can function as an air handler when paired with an evaporator coil.
