What AC installation actually costs in Vancouver WA (2026).

An AC-only install keeps your existing gas furnace as the air mover and adds cooling to it: a new outdoor condenser, a matched indoor evaporator coil, a properly sized line-set, electrical, the mechanical permit (from your city, or from Clark County outside city limits), and full commissioning.

What drives AC installation cost.

Four things move an AC installation price: tonnage, SEER2 tier, coil match and electrical work.

1. Tonnage (home size, but measured, not guessed).

Bigger homes need more cooling capacity, and each step up in tonnage adds cost. Square footage is only a starting point: newer, tighter homes often size smaller than rule-of-thumb math suggests, which is why we run a Manual J load calculation on every quote. An oversized AC short-cycles and will not dehumidify, so an extra ton you do not need leaves the house clammy.

2. SEER2 tier.

SEER2 tier is the biggest lever you control. Our AC lineup runs three tiers:

• Good: Ameristar A5AC4, 14 SEER2. Single-stage, scroll compressor, 10-year parts warranty. American Standard's economy brand, built on the same parent platform. Best fit for rentals, fixed budgets, or a furnace that is still in good shape.
• Better: American Standard Silver 14 (5A7A4), 14.3 SEER2. Single-stage cooling under the American Standard name, a step up from the Ameristar value line.
• Best: American Standard Gold 17 (5A7A7), 17 SEER2. An inverter-driven multi-speed compressor adjusts its speed to the load, for more consistent cooling and enhanced humidity control. It tops our AC-only lineup; American Standard's variable-speed Platinum air conditioners rate higher.

Higher SEER2 means lower running costs every summer. Whether the Best tier pays back depends on how long you plan to stay; our SEER2 guide walks that math for your power bill.

3. Coil match.

The indoor evaporator coil on your furnace must be the AHRI-matched pair for the new outdoor condenser, or the rated SEER2 and the manufacturer warranty do not hold. With the R-454B refrigerant transition a new condenser almost always needs a new coil, which is why our installed price already includes a matched coil.

4. Electrical.

A central AC needs its own 220V circuit. If your panel has the space, a new dedicated circuit for the outdoor unit runs $300 to $700. Older homes with a full or undersized panel may need a 200A panel upgrade, which runs $3,000 to $5,000 in Vancouver. We scope electrical during the walkthrough and put it in the written quote as its own line, so the number you sign is the number you pay.

The mechanical permit is included in our installed price (we always pull it), and most AC installs are completed in a single day.

Is a heat pump worth it over a straight AC?

A heat pump is often the better long-term value if your furnace is aging: a heat pump cools exactly like an AC but also heats efficiently, so it can retire the furnace as your primary heat source. A ducted heat pump runs $8,800 to $27,200 installed in Vancouver, WA in 2026, against $7,400 to $16,800 for AC only. Do not count on a Clark PUD rebate to close that gap: it pays only on homes heated with electricity today, and only through its Contractor Network, which we are not in. If the furnace is newer and you just need cooling, a straight AC is the right call. Our heat pump cost guide covers what moves that price.
