Central Air Installation in Mercer Island, WA
Whole-home central A/C sized to your Eastside home — ducted systems installed, balanced, and permitted for Mercer Island homeowners.
Central air installations on Mercer Island are permitted and balanced around the island's terrain, since a shoreline home and a ridge-top house near Rotary Park rarely need the same ductwork approach.
Symptoms we see every week in Mercer Island
- Adding cooling to a ducted home with none

Spec'd to your Mercer Island home
We size every system to your actual demand — not a one-size guess. Here's what a typical central air installation includes:
| Efficiency | Up to 22 SEER2 |
|---|---|
| Capacity | 1.5–5 tons |
| Compressor | Variable-speed |
| Permit | Pulled & signed off |
Central Air Installation in Mercer Island: what's different here
Elevation on the island runs from about 18 feet at the lakefront to almost 400 feet near the ridge, so equipment placement, condensate drainage and access change from block to block. To add central air to an older Mercer Island home in East Seattle, we first check whether the existing furnace ducts are large enough. If not, a heat pump with duct changes or ductless heads may cost less.
Permits and inspections
A new central air system needs a mechanical permit and usually an electrical permit for its circuit. Mechanical and plumbing permits in Mercer Island go through the City of Mercer Island Permit Center. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities and rebates
Mercer Island homes get electricity from PSE, and most have PSE natural gas. Mercer Island homeowners may qualify for utility, state or federal rebates. We point you to the current programs for your address before you sign.
