The install
Heat Pumps Installed in Hampton
Heat pumps installed in Hampton homes and businesses are sized to the building and set up to heat in winter and cool in summer. The size comes from the rooms, the windows and the insulation, measured the way the ACCA Manual J method lays out, not from the tag on the old unit.
A heat pump is a split system, so the job spans the yard, the wall and the closet, in residential and commercial buildings alike. We quote all of it before we start and clean up before we leave.
- Outside
- The outdoor unit, set level on its pad beside the house.
- Inside
- The air handler, in a hall closet, the garage or the attic.
- Between
- An insulated copper line set run through the wall.
- On the wall
- A heat pump thermostat that runs both modes and the backup heat.
Why a heat pump
A Heat Pump Heats and Cools
A heat pump moves heat instead of burning fuel, so the same system warms the house in winter and cools it in summer.
In winter
- Outdoor air
- Outdoor coil
- Your rooms
The outdoor coil gathers heat from the outside air, even on a cold morning, and the air handler carries it into the house.
The reversing valve flips the flow between seasons
In summer
- Your rooms
- Indoor coil
- Outdoor air
The flow runs the other way: heat is pulled out of your rooms and shed by the outdoor unit, the way a central air conditioner works.
No flame in the house
A heat pump runs on electricity, so there are no burners, no flue and no fuel delivery. Many homes swap a separate furnace and air conditioner for a heat pump that does both jobs.
Keep the furnace if you like
Where a home already has a gas furnace, a heat pump can pair with it as a "dual fuel system": the heat pump carries the mild days and the furnace takes over in deep cold.
How it goes
How a Heat Pump Installation Runs
An installation runs from a load calculation through equipment choice, the install, backup heat setup and a test in both modes.
- Load calculationWe measure the rooms, windows and insulation and run a "Manual J load calculation". An oversized heat pump drifts into "short cycling", and an undersized unit leans on its backup heat all winter.
- Equipment choiceWe match the outdoor unit and the air handler to that load and lay the options side by side: efficiency, fixed-speed or variable-speed, all-electric or paired with a gas furnace.
- The installThe outdoor unit goes on a level pad, the line set is run and insulated, and the air handler is set and connected to the ducts. The refrigerant circuit is pressure-tested and pulled to a vacuum before it is charged.
- Backup heat setupWe wire the "auxiliary heat strips" in the air handler and set the thermostat so they come on only when the heat pump needs help, not on every chilly morning.
- Test in both modesWe run the system in heating and in cooling, check airflow and "static pressure" at the ducts, show you the thermostat, and clean up the closet and the yard.
Lowering the cost
Heat Pump Tax Credits and Rebates
Federal tax credits and utility rebates can lower the cost of a heat pump, and their terms change by year.
Timing matters most when the old air conditioner is near the end of its life as well, since the heat pump takes over its job and the furnace's. With the federal 25C credit and a utility rebate in hand, that swap can come in under a like-for-like furnace replacement. Check the current rules for the model on your quote before you count on them.
- Federal tax credit
- Utility rebate
- A lower net cost
What sets the price of your install
- System sizeThe load calculation sets the capacity, and capacity moves the price more than anything else.
- Efficiency and speedHigher-efficiency and variable-speed equipment costs more up front and less to run.
- Backup heatThe size of the heat strip kit, or a pairing with the gas furnace you already have.
- Wiring and ductsA new circuit, a new pad or duct changes the house needs for the new air handler.
