Questions About The Price
How much does tonnage change the price?
Very little: $6,700 for 2 ton, $6,900 for 3 ton, $6,940 for 4 ton, $6,980 for 5 ton. Sizing is a comfort decision, not a budget one, and we size the unit to the house.
When is the $1,400 electrical work needed?
On a new installation, when 220V has to be brought to the outdoor unit. A straight replacement of an existing air conditioner does not carry that line.
Can I replace the furnace at the same time?
Yes, both can be done in one visit. Replacing the furnace adds $3,300 for an 80% AFUE unit or $4,500 for a 96% one to the air conditioner price.
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.
Central Air Conditioning Installation Cost in Seattle and Tacoma
Central air conditioning installed by EverHeat Solutions starts at $6,700 for a 2 ton system and runs to $6,980 for a 5 ton one. Tonnage barely moves the price, so we size the unit to the house rather than to the budget, and the quote includes the equipment, the labor, the permit and our 3-year labor warranty.
What actually moves a central AC quote is the work around the unit. A new installation usually needs 220V brought out to the condenser, which is $1,400, and a concrete pad is $150. Many homeowners also replace an aging furnace in the same visit, which adds $3,300 for an 80% AFUE unit or $4,500 for a 96% one.
The instant estimate runs the same arithmetic you see in the tables above, and a free in-home assessment confirms the final number before anything is ordered.
