AfterHVAC Company in Hobart, WA
Most Hobart homeowners pay between $150 and $700 for furnace or AC repair, with full AC installations running $3,500 to $7,500. We’re Coldharbour Heating & Air, and we dispatch crews from our Seattle office to Hobart daily. Hobart’s rural elevation, propane-dependent heating, and custom-built homes on large lots create HVAC challenges you won’t find in suburban Maple Valley or Issaquah. Call us at (817) 402-2972 for a free estimate.
Why Hobart Homes Are Different
Hobart sits in the Cascade foothills southeast of the Green River Valley, high enough to see more sub-freezing nights than lowland King County suburbs. Puget Sound Energy’s natural gas mains don’t reach this unincorporated community, so nearly every home runs on electric heat pumps, propane furnaces, or some combination. That means a corroded propane regulator or an undersized tank running dry in January is a routine service call for us, not a novelty.
The housing stock reinforces this. Hobart’s properties are mostly rural single-family homes and hobby farms on large lots, many custom-built or owner-built rather than tract development. We regularly find non-standard duct layouts, propane systems paired with wood-stove primary heat, and outdoor condenser units buried in debris from the dense surrounding tree canopy. The heavier precipitation and consistent winter freeze events push heat pumps into auxiliary or emergency heat mode more often per season than systems just 10 miles west. A technician working here needs to understand propane combustion safety, heat pump defrost cycles, and how to size equipment for homes that weren’t built to any standard plan.
Our Main Hobart Services
These are the three services Hobart homeowners call us about most often. Each has its own dedicated page with deeper detail on local conditions and pricing.
AC Repair in Hobart
Hobart’s dense tree canopy and wet winters mean outdoor condenser coils clog with needles, moss, and mud more aggressively than in cleared subdivisions. We clean the coils, check refrigerant levels (the cooling fluid your AC needs to run), test capacitors (the electrical components that start the compressor), and verify that your heat pump’s defrost board is cycling properly. A failed capacitor in July or a refrigerant leak discovered during the first hot spell are common calls here. AC Repair in Hobart covers typical costs and what same-day service looks like in this area.
Furnace Repair in Hobart
With no natural gas available, Hobart furnace work is almost entirely propane systems and electric heat pumps with auxiliary heat strips. We replace propane regulators, troubleshoot ignition failures in LP furnaces, and diagnose why a heat pump locked out and forced the home onto expensive emergency heat. A propane furnace with a cracked heat exchanger is a safety issue we treat as urgent. Furnace Repair in Hobart explains our process and what a winter no-heat call looks like.
AC Installation in Hobart
New system installs in Hobart require load calculations that account for the elevation, the home’s often non-standard construction, and whether the property has adequate electrical service or propane infrastructure. We size heat pumps for the heating load first, not just cooling, because Hobart’s winters demand it. Duct modifications are common. AC Installation in Hobart walks through the full process, including how we handle the written fixed-price quote and schedule the work.

What pushes Hobart prices toward the higher end: propane system work requires specialized training and parts; non-standard duct layouts add labor; and rural drive times are built into our scheduling. We give you the written price before any work begins, and that number doesn’t change at the door. That’s The Kingswell Way, not a policy we apply case by case.

FAQs About HVAC Company in Hobart, WA
We answer calls with a live person 24 hours a day, and we prioritize no-heat calls during freeze events and no-cool calls during hot spells. Most Hobart emergency calls are scheduled same day or next day depending on current volume. Call (817) 402-2972 to check today’s availability.
King County handles permitting for unincorporated Hobart. Most furnace and AC replacements require a mechanical permit; we pull the paperwork as part of our standard process and include the permit cost in your written quote. You don’t need to visit the county office yourself.
Hobart’s elevation and Cascade foothill exposure produce more sub-freezing nights than lowland suburbs. Below roughly 35°F, your heat pump loses efficiency and calls on auxiliary heat strips or a backup propane furnace. If the system runs constantly or your bill spikes, the issue is often an undersized heat pump, a failed defrost sensor, or a propane backup that isn’t firing. We diagnose which it is and give you the repair price in writing before starting work.

What Hobart Customers Say
"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
- Natalie Esposito"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
