HVAC in Union, WA
We work as an HVAC contractor in Union, WA, the Hood Canal village in ZIP 98592, installing and repairing heat pumps, ductless systems and furnaces. Union visits go on days we already run SR-106, after we confirm your equipment and likely parts by phone.
Union sits on the Great Bend, where Hood Canal hooks east toward Belfair, and most homes here look straight at salt water. As an HVAC contractor serving Union, WA from Bremerton, we reach the village in roughly 45 to 50 minutes: SR-3 south to Belfair, then the winding SR-106 shoreline past Twanoh State Park.
That drive shapes how we work. We confirm your equipment model when you call, load the truck for the likely fix before we leave, and pair Union visits with Belfair or Hoodsport calls when the schedule allows. Part-time owners can meet us on site or arrange access, since a lot of cabin work happens while the house sits empty.

Shoreline humidity, weekend cabins and part-time heat in Union
Union’s housing is a mix of older waterfront cabins that grew in stages, full-time homes on the hillside above SR-106, and newer builds around Alderbrook. The common thread is moisture. Air off the canal is damp most of the year, crawl spaces stay wet, and outdoor units within sight of the beach catch salt spray on windy days.
Seasonal use adds its own risk. A cabin held at 50°F all winter can grow mold in its ductwork, and a heat pump that only runs on weekends may hide a slow refrigerant leak until the first warm spell. Wall heaters and baseboard are still common in the original cabin sections, which is why ductless mini-splits are often the cleanest upgrade here.
- Salt exposure: coil corrosion and rusted cabinet screws on units facing the water
- Crawl space moisture: sweating duct runs, fallen insulation and musty supply air
- Freeze risk: empty cabins during an Arctic outbreak, when a failed system can go unnoticed for days
From Alderbrook to the Dalby Waterwheel: a typical Union service call
Union is small enough that directions usually start with a landmark: past the Alderbrook entrance, a few driveways beyond the Dalby Waterwheel, up the hill from the SR-106 curve. Many driveways drop steeply toward the water, so we ask ahead about parking and where the outdoor unit sits.
A common winter call goes like this. An owner drives out on Friday night and finds the cabin at 48°F with the heat pump blowing cool air. Often a defrost board or sensor has failed, the unit iced over during a cold, damp week, and the heat strips carried the load until a breaker tripped. We check the heat pump repair basics first, then talk honestly about whether a salt-worn unit deserves another repair. Our guide to heating a Hood Canal cabin year-round covers the bigger options.

HVAC services we provide in Union
Hood Canal’s mild, damp winters suit a properly sized heat pump, and a coated coil on a raised pad keeps a Union waterfront unit working longer.
Cabins with add-on rooms and no ductwork heat well with one head per zone, and a weekend home can hold a safe low temperature cheaply.
An annual visit rinses salt film off the coil, clears the condensate path and confirms defrost works before the first cold snap on the canal.
Cabins closed up for months can smell musty at startup; we inspect crawl space ducts for moisture damage before recommending any cleaning.
What Union households on the Great Bend can count on from us
Union homes face salt water, sit over damp crawl spaces and often stand empty midweek. Our standard practices are built for exactly that.
Corrosion tracked with dated photos
On units within sight of the canal, we photograph the coil and cabinet fasteners on the water side every visit. Over a few winters those photos show whether corrosion is slow or speeding up, which makes a repair-or-replace call a matter of evidence. Our salt air corrosion guide explains what we look for.
Crawl-space ducts inspected before cleaning is offered
A musty smell at a cabin startup does not automatically mean dirty ducts. We look under the house for wet insulation and disconnected runs first, and recommend duct cleaning only where it will actually help.
Refrigerant handled by the rules
When a salt-pitted coil starts leaking, topping it off every spring only hides the problem. Our EPA Section 608–certified techs recover refrigerant properly, find the leak and tell you plainly whether the coil or the whole unit should go.
Sizing that fits weekend use
A cabin held at a low setback all week and warmed up on Friday needs different equipment than a full-time home. Manual J and Manual S keep a new heat pump installation from short-cycling in the damp shoulder seasons.
Buying a Union cabin? Have the heating checked before closing
Waterfront cabins along SR-106 change hands often, and the heating system is easy to overlook in a sale. A general home inspection may confirm the heat turns on; it will not always tell you how many winters an outdoor unit has left against canal spray.
Before you close, have someone who works on the equipment look at:
- Model and serial plates on every unit, to date the equipment
- Coil fins and cabinet screws on the canal side, where salt corrosion starts
- Crawl-space ducts for sagging insulation, disconnected runs or standing water (see damp crawl spaces and ducts)
- Permit history for past installs, checked with Mason County, since unpermitted work can mean unverified wiring or line sets
- Any buried or abandoned oil tank left from the cabin’s earlier heating days
FAQ
HVAC questions from Union homeowners
Can you service a Union cabin when we’re not there?
Yes, in many cases. We confirm access, the location of the outdoor unit and electrical panel, and any gate or lockbox details ahead of time. After the visit we send notes and photos of what we found. If a repair needs your decision, we call before doing the work rather than leaving you a surprise.
Does salt air from Hood Canal really shorten heat pump life in Union?
It can. Units within a few hundred feet of the water collect a salt film that speeds coil and fastener corrosion, especially on the side facing the canal. Rinsing the coil during maintenance, choosing a unit with coated coils and placing it out of direct spray all help. Homes higher on the hillside see much less of this.
What does it cost to replace a salt-worn heat pump at a Union waterfront cabin?
Regional planning ranges run about $9,500–$13,500 for a standard ducted heat pump and $12,500–$16,500 for a cold-climate model. On the canal, ask each bidder to include a coated coil, a raised pad or stand and stainless or coated fasteners, and to show any trip charge separately. Cabins without ducts often cost less with ductless heads. Only a site visit sets the real number.
