The independent heating and cooling company across Washington
AC Installation in Sammamish, WA — Book a Visit Today
If your current cooling system is past repair or you have never had cooling at all, we size and install new equipment for Sammamish houses. AC installation in Sammamish often means adding a heat pump instead, since it cools in July and heats through the wet months on the same refrigerant lines. We measure the house rather than copying the label off the old unit, and we look at duct capacity before promising quiet, even air. Two-story plateau homes with a hot upstairs usually need both addressed. Tell us which rooms never cool down, then call or send the quote form for a walkthrough.

How do you size a new AC system?
We measure the house: square footage, window area and orientation, insulation, and duct capacity. Then we match equipment to that load. Oversized systems short cycle and leave humidity behind, so bigger is not better. The measurement happens on the visit, before any equipment is ordered.
Should I repair my air conditioner or replace it?
If the system is under about ten years old and the failed part is common, air conditioner repair usually makes sense. If the compressor is gone, the refrigerant is obsolete, or you've paid for two repairs in two seasons, we'll price both paths and let you compare.
Can you install AC in a house with no ducts?
Yes. Ductless mini-splits mount an indoor head on the wall or ceiling and connect to an outdoor unit through a small penetration. They work well for older homes across Oregon and Washington, additions, converted attics, and rooms one central system never reached.
How long does an installation take?
A straight changeout of an existing central system is typically one day. Adding ductwork, moving the indoor unit, or a multi-zone ductless install can run two or three days. We'll give you the schedule in the written scope so you can plan around it.
How soon can you get to a Sammamish home?
Call or send a message with your address and what the system is doing, and we will give you a real window rather than a vague promise. Summer heat runs and the first hard cold snap fill the schedule fastest, so no-cooling and no-heat calls get sorted ahead of maintenance visits. Before we arrive, you can check the thermostat batteries and settings, look for a tripped breaker, change a dirty filter, clear leaves and yard debris from around the outdoor unit and confirm vents are open. If you ever smell gas, leave the house first, call 911 or your gas utility, then call us.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. Describe the noise, the smell, the temperature, and when it started. That detail helps us bring the right parts and gives you an honest idea of the visit ahead.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant behaviour and the outdoor unit. We tell you what failed and why, in plain language, before anyone reaches for a part or a price.
- Step 3
You choose the repair
We lay out the fix, any parts on order, and what happens if you wait. Once you agree, we do the work and confirm the system holds temperature before we pack up and leave.

Why homeowners call us
- Heat pumps are our normalIn this region heat pumps outnumber furnaces, so defrost boards, reversing valves and short cycling in wet weather are everyday work for us. We know how these systems behave in a cold December rain, not just on a test bench.
- Wet winter defrost problemsIce on the outdoor coil, a unit that runs and runs without warming the house, puddles that refreeze under the pad. We trace whether it is a sensor, a stuck valve, drainage, or airflow, then fix the actual cause.
- Filtration after smoke seasonWildfire smoke turned indoor air quality into a real conversation here. We look at filter fit, return sizing and IAQ options that your blower can actually push air through, rather than choking the system with the wrong media.
- We explain before we chargeYou get the diagnosis, the options and the trade-offs before work starts. If a repair is not worth it on an old system, we say so. No pressure, no jargon dumped on you at the door.
