Whole-home
One system for the whole house.
A ducted or multi-zone heat pump serves every room from one or two outdoor units. We choose it from your load calculation, then show you the number on the quote.
Good for
A house with ducts in good shape
A house that wants one thermostat and one schedule
Replacing a furnace and central air together
A big renovation that opens the walls anyway
At the visit and after
From the first walk-through to commissioning.
- 01
Step 1: We inspect the ducts
Size, leaks and layout. Ducts that are too small for the new load get repaired or replaced, and we say which.
- 02
Step 2: We size the system
Heat loss for the whole house, then equipment whose published output at your design temperature covers it.
- 03
Step 3: We plan the backup
Keep the boiler or furnace in place, or retire it. Either way, the thermostats are set so you can tell which one is running.
- 04
Step 4: We install and commission
Outdoor unit, indoor air handler, wiring, condensate, a charge check and a walk through the controls.
- 05
Step 5: We file the rebate
As a registered vendor, we submit the Efficiency Maine paperwork and tell you when it has gone in.
What drives the cost
What decides the price.
These are the lines on your quote. We do not post prices, because two houses never need the same work.
Capacity
From the load calculation, not from the square footage.
Duct condition
Reused, repaired or replaced.
Single or variable speed
Variable-speed equipment runs more gently and costs differently.
Electrical work
Service size, panel space and wire length.
Old equipment
Left in place, disconnected or removed.
Permits and rebate
Each is a line on the quote.
Whole-home questions.
What size system do I need?
The one your load calculation says, not the biggest one that fits. We measure the house, note the insulation and windows, and calculate heat loss room by room. Oversized equipment cycles on and off, and an undersized system leans on the backup.
Will I still need my boiler or furnace?
Not always. Some homeowners keep it for the first winter, or for one wing the heat pump does not reach, and some retire it after the first season. We tell you which fits your house at the visit, and we do not remove anything you want to keep.
Do you pull permits?
Yes. The electrical work needs a permit, and the quote lists the permits the job needs. Your town's inspector signs off before we call the job finished.
What does the warranty cover?
The manufacturer warrants the equipment, and the terms depend on registering it, which we do for you. Our own workmanship terms come in writing with the quote, with what they cover and what they leave out.

We will measure, calculate and write it down before you decide.
