Through-the-Wall Heat Pump Replacement in Mechanicsburg, PA

Have an older through-the-wall heat pump and wonder what could replace it? This Metro HVAC project on Geneva Drive in Mechanicsburg, Pennsylvania, shows one example of a different equipment arrangement: a new Daikin FIT inverter heat pump paired with an indoor air handler.

The starting point: the original through-the-wall heat pump

The original equipment photo shows the older unit inside the home’s utility space, with ductwork connected above it. Metro HVAC replaced this through-the-wall heat pump as part of the project.

For a homeowner with a similar setup, this is a useful starting point for a conversation about replacement. The existing equipment’s location and configuration help define the work, but the options for another home still need an on-site evaluation.

The replacement: Daikin FIT with an indoor air handler

Metro HVAC installed a new Daikin FIT inverter heat pump and an indoor air handler. The outdoor photos show the Daikin unit on a raised metal equipment stand beside the home’s exterior wall.

This was a change from the original through-the-wall equipment to an outdoor heat pump and indoor air-handler arrangement, rather than simply installing another identical unit.

What does inverter technology mean for your home?

An inverter heat pump can vary its compressor speed to respond to changing heating and cooling demand, rather than operating only at one fixed speed. The goal is to adjust output to the comfort demand instead of relying solely on full-speed operation. Daikin explains this approach in its guide to inverter technology.

Equipment selection and installation still matter. The U.S. Department of Energy identifies sizing, refrigerant charge, and duct leakage as factors that can affect heat-pump performance. Learn more in its heat-pump installation guidance. A new equipment label alone does not establish a home’s future energy savings.

Behind the scenes of the installation

The installation-process photo shows service gauges, hoses, and a vacuum pump connected to the outdoor unit. Together with the original-equipment photo, these images document the equipment change and work in progress.

The outdoor images were taken while service equipment was still present. They are installation photos, not final-cleanup photographs.

Questions about replacing a through-the-wall heat pump

Can my home use a separate outdoor heat pump and indoor air handler?

This Geneva Drive project is one example of that change. Whether the same approach suits another property depends on the home. An evaluation should consider heating and cooling needs, equipment space, ductwork, and electrical requirements before recommending a system.

What should I have ready when asking about replacement?

A photo of the existing equipment, a readable model-label photo, and a description of any comfort concerns provide a useful starting point. Share those directly with Metro HVAC so we can discuss the next step for your home.
