Most AC Installation projects in Boulevard Park run $3,500-$7,500, and every job starts with a written price before we bring a single tool inside. We’re Coldharbour Heating & Air, and our crews serve Boulevard Park from our Seattle office, dispatching with the load calculations and equipment sizing this neighborhood’s unusual housing stock demands.

Boulevard Park isn’t like other King County neighborhoods. The modest ranch and split-level homes built between the 1950s and 1970s were never designed for air conditioning, and the Port of Seattle’s Residential Sound Insulation Program has since tightened hundreds of those envelopes with upgraded windows and added attic insulation. That combination creates a specific challenge: homes that now need smaller, more precisely sized systems than their original furnaces assumed. We run a fresh Manual J load calculation on every Boulevard Park installation because the old nameplate tonnage is almost always wrong.
And for properties off the natural-gas grid, we’re regularly installing propane-fired furnaces and cold-climate heat pumps where the only previous option was window units or nothing at all. The exposed lots along South 116th and South 120th, with no windbreak sheltering the outdoor unit, demand extra attention to condenser placement and defrost-cycle strategy. We’ve learned where to set equipment so it survives the wet Puget Sound winters without the grief.
Why Coldharbour Heating & Air Is Boulevard Park’s Preferred AC Installation Company
We’ve been working to The Kingswell Way since 2003: say the price before the work starts, show up in the window promised, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. Boulevard Park homeowners get the same written promise every time.
Our technicians are background-checked and uniformed, trained on nine major residential brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters here because many Boulevard Park homes still run original or once-replaced equipment from manufacturers no longer common in new construction. We stock parts and have supplier relationships that keep wait times short for older systems.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail trees, no callbacks tomorrow morning. When the June 2021 heat dome pushed SeaTac to 108°F, we fielded non-stop calls from Boulevard Park residents who’d never considered AC before. We haven’t forgotten that week, and we haven’t gone back to treating cooling as optional in this corridor.
Every repair carries our 365-Day Done Right Promise: a written guarantee, issued before the technician leaves, that brings us back at no charge if the repair fails within a full year. It’s not a verbal assurance. It’s on paper, every time.
Furnace Installation in Boulevard Park
Furnace Installation in Boulevard Park demands more than swapping a box. The 1950s-1970s housing stock here was built when a gas furnace was the whole HVAC picture, and many of those systems are now two or three replacements deep without anyone recalculating what the house actually needs. After the Port of Seattle’s sound-retrofit upgrades doubled attic insulation and replaced windows on hundreds of homes, the heat load dropped 20-30% below original design. We pull the insulation-program documentation for the address before we size anything.
When Propane Replaces Natural Gas
Properties beyond the gas main, particularly larger lots and outbuilding setups, often need propane-fired equipment. We size the tank, run the lines, and match the furnace to the actual heat loss, not the old system’s guess. Propane installations in Boulevard Park require specific venting and combustion-air strategies we account for in the initial load calculation.
Short-Cycling and Oversized Equipment
The most common problem we find: a furnace that fires for three minutes, shuts off, and fires again. That’s oversized equipment hitting its high limit in a tightened envelope. Our fix is a properly sized replacement, not a band-aid on the thermostat. The written price covers the full correction, including duct modifications if the original runs are too small for modern airflow requirements.
HVAC Installation in Boulevard Park
HVAC Installation in Boulevard Park means thinking about the whole system, not just the box that heats or cools. The old furnace, the ductwork sized for a different era, and the new tight envelope all have to work together. We start with a Manual J load calculation, check static pressure across the existing duct runs, and only then specify equipment. Most full system replacements here fall in that $3,500-$7,500 range, with the final number depending on whether we’re adapting existing ducts or replacing them.
Heat Pump Retrofits for Tightened Homes
Heat pumps are increasingly the right choice for Boulevard Park’s mild winters and newly insulated homes. A properly sized cold-climate heat pump handles heating down to the temperatures this neighborhood actually sees, while providing efficient cooling that wasn’t part of the original 1960s design. We verify the ductwork can deliver the airflow the heat pump needs, or we specify modifications upfront in the written price.
Outbuilding and Workshop Conditioning
Many Boulevard Park properties include detached workshops, garages, or studio spaces that need independent climate control. Mini-split installation gives these spaces their own zone without tying into the main duct system. We size these for the exposed, unsheltered conditions common on larger lots, placing outdoor units where winter wind won’t trigger unnecessary defrost cycles.
Trusted Brands We Service in Boulevard Park
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. Our Seattle-area warehouse stocks common components for Rheem, York, and Daikin systems, which means faster turnaround when Boulevard Park homeowners need a part that isn’t sitting on a national distribution shelf. We don’t push one brand over another. The right equipment is the one that matches your home’s load, your duct capacity, and your preference for gas, propane, or electric operation. Our technicians carry certifications across the full range, so the person who shows up can work on whatever you have or whatever we recommend.
Common AC Installation Problems We See in Boulevard Park Homes
- Oversized condensers on sound-retrofit homes. The original tonnage from a 1970s furnace nameplate is almost always too large after Port of Seattle insulation upgrades. The new AC or heat pump short-cycles, fails to dehumidify, and ices up on mild days. We recalculate every time.
- Undersized ductwork choking modern blowers. The 1950s-era duct runs in these ranch homes were sized for heating-only airflow. A heat pump or modern AC needs more volume. Without static-pressure testing, the system never reaches its rated SEER2 efficiency and the blower motor strains itself to death.
- Condensers placed on the weather side of exposed lots. Boulevard Park properties without windbreaks, common along the airport corridor, subject outdoor units to direct winter wind. Defrost cycles run constantly, refrigerant charges drift, and efficiency collapses. We site equipment with this in mind.
- Ignoring the propane or electric-only reality. Homes off the natural-gas grid need equipment selected for that fuel source, not a gas furnace with the pipe capped. We size propane systems and electric heat pumps for the actual energy available at the property.

FAQs About AC Installation in Boulevard Park
Yes, almost always downward. The window replacements and added attic insulation drop your home’s heat load 20-30% below what the original furnace assumed. We pull the Port of Seattle documentation for your address and run a fresh Manual J before specifying equipment. Call (817) 402-2972 and we’ll check your retrofit status during the free estimate.
Yes, and it’s often the most efficient choice for this climate. A cold-climate heat pump heats efficiently through Puget Sound winters and provides cooling that wasn’t part of your home’s original design. We verify your ductwork can move the required airflow, or we include duct modifications in the written price. The June 2021 heat dome convinced a lot of Boulevard Park homeowners that cooling isn’t optional anymore.
Short-cycling means the equipment is oversized for the actual load, or the ductwork is too restrictive. In Boulevard Park, both are common: the original furnace was sized for a leaky 1960s envelope, and the ducts were built for heating-only airflow. After sound-retrofit upgrades tighten the house, that old tonnage is wildly too large. We size to the new load, not the old nameplate.
It transformed demand overnight. SeaTac hit 108°F, and thousands of homes with zero cooling infrastructure became uninhabitable. Boulevard Park saw more heat pump and AC retrofit requests in the two years after that event than in the prior decade combined. We’re now installing cooling as standard, not luxury, in this neighborhood.
Yes, regularly. Mini-split systems give detached workshops, studios, and garage spaces independent zoning without tying into undersized main ductwork. We size for the exposed, unsheltered conditions common on larger Boulevard Park lots, placing outdoor units where winter wind won’t cause defrost problems. The written price covers the full installation, including electrical connections.
