Questions About The Price
Does a larger heat pump cost much more?
Very little: $7,500 for 3 ton, $7,540 for 4 ton, $7,580 for 5 ton. We size the unit to the house rather than to the budget.
Does a heat pump always need new electrical work?
Not always. The $1,400 line applies when 220V has to be run out to the outdoor unit on a new installation. If the heat pump replaces a system that already has the circuit, it does not apply.
Is a heat pump more expensive than central air conditioning?
At the same tonnage, yes, by about $600: $7,500 against $6,900 for a 3 ton system. A heat pump also heats the house, so it can take over from the furnace.
Is the estimate free?
Yes. The in-home assessment is free and there is no obligation to book the work afterwards.
Does the price include permits?
Yes. City permits and the paperwork are pulled in your name and are part of the job, not an extra line.
Can the price change once the work starts?
You receive an itemized quote before anything begins, and customers specifically note that there were no onsite extras added later.
What payment methods do you accept?
Check, cash, Zelle, and online payment, whichever is easiest for you.
Do you offer rebates or financing?
We do not currently offer manufacturer or utility rebates ourselves, but we are happy to talk through what is available and how it fits your budget and timeline.
Heat Pump Installation Cost in Seattle and Tacoma
A heat pump both heats and cools, which is why it has become the default recommendation for this climate. Installed, ours start at $7,500 for a 3 ton system and reach $7,580 at 5 ton. That is roughly $600 more than central air conditioning at the same size, and in return the system covers the heating season as well.
A new installation generally needs 220V run to the outdoor unit, which is $1,400, and a pad at $150. If the furnace is also at the end of its life, replacing it in the same visit adds $4,200 for an 80% AFUE unit or $5,300 for a 96% one. Home size is handled in four bands, from $100 to $450.
