We serve Hobart from our Seattle dispatch office, with crews making the drive southeast past Maple Valley into the Cascade foothills several times a week. We’re familiar with the long gravel drives off SE 216th Way, the custom-built homes on multi-acre lots, and the reality that out here, every installation involves a propane furnace or heat pump decision because Puget Sound Energy’s natural gas mains don’t reach this far. That local knowledge changes how we size equipment, how we pair systems, and what we check before we leave.
Why Coldharbour Heating & Air Is Hobart’s Preferred AC Installation Company
We’ve been working in the Kingswell network since 2003, and our AC Installation team has spent years learning the specific challenges of rural King County properties. Hobart isn’t a suburb with tract homes and uniform duct layouts. It’s a community of single-family homes, hobby farms, and owner-built cabins where every job starts with questions about propane tank size, auxiliary heat staging, and whether the outdoor unit will survive winter under heavy tree canopy.
Our technicians are background-checked, uniformed, and trained on nine major residential HVAC brands. We show up in the arrival window we promise, leave the job site clean, and put our 365-Day Done Right Promise in writing before we leave. If a repair fails within that full year, we come back and correct it at no charge. No argument, no additional invoice.
Phones are answered by a live person 24 hours a day, 7 days a week. You’ll never hit a voicemail tree, even at midnight on a Saturday.
Furnace Installation in Hobart
Furnace Installation in Hobart almost always means a propane-fired unit, not natural gas, because PSE’s gas distribution ends well west of here. When we quote furnace work in Hobart, we’re sizing for a fuel source that requires its own regulator, tank sizing verification, and combustion-air calculation. Most furnace installations in this market run $150-$700 for the furnace component within a broader system replacement.
Propane System Integration
We don’t treat the propane furnace as an afterthought. Every furnace installation we perform includes verification of the existing regulator capacity, tank size, and line pressure. An undersized tank that runs dry in January is a common Hobart failure mode we’ve corrected on properties from the Cedar River watershed up toward Taylor Mountain.
Cold-Climate Sizing
Hobart’s elevation in the Cascade foothills produces more sub-freezing nights than lower-elevation communities like Renton or Kent. We size propane furnaces with adequate BTU output for those nights, and we set heat pump balance points so the transition to auxiliary heat happens smoothly, not as an emergency.
HVAC Installation in Hobart
HVAC Installation in Hobart is fundamentally a dual-fuel decision for most homeowners: pairing a heat pump with an existing propane furnace, or specifying a cold-climate heat pump with propane backup. Because natural gas mains don’t reach this rural community, that choice, not the equipment brand, is what determines whether your home stays warm on a foothill January night. Full system installations in Hobart typically fall in the $3,500-$7,500 range depending on equipment tier and existing infrastructure.
Load Calculation for Exposed Properties
We never quote tonnage off square footage alone. Hobart’s exposed, wind-unsheltered lots and dense tree canopy change the real heating and cooling load. Oversized systems short-cycle and never dehumidify during our wet shoulder seasons. We perform a full Manual J load calculation that accounts for west-facing walls, roof exposure, and wind patterns across open acreage.
Debris and Drainage Planning
The surrounding canopy that makes Hobart beautiful also drops needles, leaves, and branches year-round. We place outdoor units where they can shed snow, drain properly, and stay accessible for cleaning. A condenser buried in debris by October is a service call waiting to happen.
Trusted Brands We Service in Hobart
Our technicians are trained to install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. For Hobart customers, we stock common parts for Trane, Lennox, and Goodman systems locally, which means faster turnaround when a capacitor fails in August or a contactor sticks in February. We don’t push one brand over another. We match equipment to your home’s load, your propane setup, and your budget, then put the written price in your hand before any work begins.
Common AC Installation Problems We See in Hobart Homes
- Oversizing from square-footage guesses. A contractor who sizes by bedroom count alone will install too much tonnage for a Hobart home’s actual load. The system blasts cold air, shuts off fast, and leaves humidity hanging in the air through September and October.
- Ignoring the propane furnace pairing. A heat pump installed without verifying the existing propane regulator, tank size, or heat exchanger leaves auxiliary heat unreliable right when sub-freezing foothill nights hit. We’ve found corroded regulators and undersized tanks on calls throughout the Hobart area.
- Condenser placement under heavy drip lines. Dense tree canopy increases humidity and debris-clogging of outdoor condenser units. We see coils packed with fir needles and cottonwood fluff, and units set in low spots where winter snow and spring mud pool around the base.
- Failing to verify ductwork for the new air handler. Hobart’s custom and owner-built homes often have non-standard duct layouts. A new air handler on old ductwork can create static pressure problems, noise, and uneven temperatures from room to room.

FAQs About AC Installation in Hobart
Yes, we can add a heat pump or straight AC condenser to most existing propane furnaces, provided the air handler and ductwork can handle the airflow. We’ll verify your furnace’s blower capacity, check the propane regulator and tank size for winter reliability, and give you a written price for both the cooling addition and any recommended furnace upgrades. Call (817) 402-2972 for a free estimate.
Hobart’s elevation and frequent sub-freezing nights mean we typically specify cold-climate heat pumps with lower balance points and adequate auxiliary heat staging. A standard heat pump sized for Kent or Renton will spend too much time in emergency heat mode here, driving up electric bills. We match equipment to your actual heating load, not a generic coastal assumption.
Exposed properties with no wind shelter experience higher heat loss in winter and greater solar gain in summer, while dense tree canopy traps humidity. An oversized system short-cycles, failing to dehumidify during wet shoulder seasons. An undersized system runs continuously without reaching setpoint. We perform a full load calculation that accounts for your specific exposure, not just square footage.
Most AC installations in Hobart run $3,500-$7,500, with the final figure depending on equipment tier, ductwork condition, and whether we’re integrating with an existing propane furnace or installing a complete dual-fuel system. Furnace installation work within that scope typically adds $150-$700. We provide a written fixed price before any work begins. Call (817) 402-2972 for your free estimate.
We select placement with drainage, airflow, and maintenance access in mind, then recommend a maintenance plan that includes pre-season coil cleaning given Hobart’s heavy tree canopy. In some cases we elevate the pad or specify a snow-leg kit for units in drift-prone locations. The goal is a system you can keep running without calling for emergency service every October and January.
Out on a hobby-farm property off SE 216th Way, our crew replaced a failing 2.5-ton condenser with a Carrier cold-climate heat pump and ran a load calculation that accounted for the exposed west wall and no wind shelter from the surrounding tree line. The old system had been short-cycling on a weak capacitor all summer, and the propane furnace it paired with had an undersized tank that ran dry every January; we upsized the tank feed, set the heat pump’s balance point, and verified refrigerant charge and static pressure on the new air handler before we left.
