What affects your HVAC system price
System type & efficiency tier
A code-minimum single-stage unit costs far less up front than a variable-speed, high-SEER2 system — but the efficient tier lowers monthly bills and may qualify for rebates.
Ductwork condition
Leaky, undersized, or missing ducts add cost. Ductless mini-splits skip ductwork entirely, which can be cheaper in older homes.
Electrical & gas readiness
Switching to a heat pump may need an electrical panel upgrade; a new gas furnace may need venting or gas-line work.
Home size & load
Square footage, insulation, windows, and layout determine the system size (tonnage/BTU) you actually need.
Permits, removal & disposal
Washington permits, old-equipment haul-away, and code upgrades are part of a legitimate installed price.

Frequently asked questions
Do I need a permit to replace an HVAC system in Washington?
Yes. Washington requires a mechanical permit for HVAC replacement, and heat-pump or electrical changes may need additional permits. A licensed contractor pulls the permit and schedules inspection — Eco handles all of it as part of your installed price.
Is a heat pump worth it in the Puget Sound?
For most Puget Sound homes, yes. The mild, wet climate is ideal for cold-climate heat pumps, which heat and cool efficiently, cut energy bills, and frequently qualify for utility and federal rebates that offset the higher upfront cost.
How long does an HVAC installation take?
A straightforward AC or furnace replacement is usually a one-day job. Heat-pump conversions, ductwork, or electrical upgrades can take two days. Eco confirms the timeline in your upfront quote so there are no surprises.
Are there rebates for high-efficiency HVAC in Washington?
Often, yes. Heat pumps and high-efficiency systems may qualify for utility rebates and federal tax credits. Eco helps identify the rebates you're eligible for and factors them into your options.

“The electrician, Max, found the problem in less than 30 minutes. He located a loose wire that had cut power to two rooms and corrected it. Max is a very pleasant person and professional in every way. I'll recommend him and the company to anyone with electrical problems.”
