AfterFast, Reliable AC Installation Across Burien
Most central air conditioning installations in Burien run $3,500-$7,500, and we schedule a firm install date after a written load calculation and upfront price, never a same-day swap. We’re Coldharbour Heating & Air, and our AC Installation team serves Burien from our Seattle office, with crews who know the difference between a mitigated 1960s rambler under Sea-Tac’s flight path and an unsealed identical one two doors down. Call (817) 402-2972 for a free estimate and written price before any work begins.
Why Coldharbour Heating & Air Is Burien’s Preferred AC Installation Company
We’ve been working in Burien long enough to know that a house on SW 152nd St. can need a completely different tonnage than its neighbor across the street. That’s not guesswork. It’s what happens when the Port of Seattle’s noise-mitigation program retrofits one home with triple-pane windows, dense-pack attic insulation, and aggressive air-sealing, but not the other. Our technicians run a full Manual J load calculation on every install, and we check for hidden HRV or ERV units that mitigation crews sometimes left behind.
Our phones are answered by a live person 24 hours a day, 7 days a week. When you call (817) 402-2972, you get a human being, not a voicemail tree. We show up in the window we promise, leave the job site cleaner than we found it, and hand you a written 365-Day Done Right Promise before the technician leaves. If anything fails within that full year, we come back and correct it at no charge. That’s The Kingswell Way, and it’s how we’ve operated since 2003.
Central Air Conditioning Installation in Burien
Central Air Conditioning Installation in Burien almost always means working with post-WWII housing stock: ramblers and ranch homes built between 1950 and 1975, most without original ductwork or any cooling at all. A typical new central air system in Burien runs $3,500-$7,500, but that figure assumes we either find usable ducts or build new ones. Many Burien homes started with electric baseboard heat or gravity furnaces, so “replacement” often means first-time duct installation or a hybrid approach with ductless zones.
When Ducts Don’t Exist Yet
Homes near Three Tree Point or along Ambaum Boulevard frequently lack basement or attic space for conventional duct runs. We design low-profile duct systems or recommend ductless mini-splits for additions and outbuildings where running ducts would mean tearing into finished spaces. Every path gets a written price before we touch a tool.
Electrical Upgrades Before the Condenser Goes In
Original 60-amp or 100-amp panels in older Burien homes often can’t handle a modern condenser’s startup draw. We inspect your panel during the site walkthrough and flag any needed electrical work upfront, so you’re not surprised by a separate contractor visit after we’ve already scheduled your install date.
Furnace Installation in Burien
Furnace Installation in Burien typically pairs with air conditioning in a full system replacement, running $3,500-$7,500 for the complete package. Most Burien homes we see still run original gravity furnaces, early forced-air oil conversions, or electric baseboard systems that were never designed to move cooled air. A modern furnace matched to a new evaporator coil and condenser gives you a single system that heats and cools efficiently, but only if the ductwork and blower are sized together.
Matching the Furnace to Your Home’s Envelope
A noise-mitigated home with sealed attic and triple-pane windows loses heat far more slowly than its unsealed twin. We size the furnace output in BTUs based on actual heat loss, not the old unit’s nameplate. Oversized furnaces short-cycle, waste fuel, and die early. We don’t install equipment that fights your house.
Condensation and Crawl-Space Humidity
Burien’s marine climate keeps relative humidity elevated, especially in low-lying areas near Puget Sound. Poorly insulated ductwork in vented crawl spaces sweats, grows mold, and rots out. We insulate and seal every new duct run, and we flag existing moisture problems before they damage your new system.
Trusted Brands We Service in Burien
Our technicians train on nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Burien installations, we stock common Goodman and Rheem components locally for faster turnaround, and we size York and Daikin equipment regularly for the tight building envelopes we find in noise-mitigated homes. Every brand we install comes with manufacturer warranty registration handled by our office, plus our own 365-Day Done Right Promise on the installation labor itself.
Common AC Installation Problems We See in Burien Homes
- Nameplate tonnage guesses. We see competitors swap a 3-ton unit for a 3-ton unit without running a Manual J. In Burien’s flight-path neighborhoods, a mitigated home might need 2.5 tons while the unsealed identical house next door needs 3.5. Wrong sizing means poor humidity control, short cycling, and early compressor failure.
- Reusing 1960s ductwork. Original 6-inch galvanized ducts were sized for heating-only airflow. Modern cooling needs higher static pressure and more return air. We measure existing ducts and replace undersized runs rather than force a new system to breathe through a straw.
- Hidden HRV/ERV conflicts. Port of Seattle mitigation crews installed whole-house ventilators in some north Burien homes above 128th St. Homeowners often don’t know they exist. If tied into the return path, a new blower fights the HRV and both systems underperform. We locate and isolate them during our site walkthrough.
- Ignored crawl-space moisture. Burien’s humidity and Puget Sound proximity mean condensation on uninsulated ducts is a constant threat. We inspect every crawl space and recommend insulation upgrades or dehumidification when needed, before the new equipment goes in.
Pricing for AC Installation in Burien, WA
A typical central air conditioning installation in Burien runs $3,500-$7,500, and a complete furnace-plus-AC system replacement falls in the same range. What moves you within that band: whether your home needs all-new ductwork or has usable existing runs, whether your electrical panel needs upgrading, and whether noise-mitigation sealing changes your load calculation enough to shift equipment size. We don’t give ballpark figures over the phone that change at the door. Our technician walks your home, measures every room, checks insulation and windows, inspects the panel and crawl space, and hands you a written fixed price before any work is scheduled. That price is guaranteed. Call (817) 402-2972 to book your free estimate.

FAQs About AC Installation in Burien
Yes, it can change the tonnage by half a ton or more. Triple-pane windows, dense-pack attic insulation, and aggressive air-sealing reduce heat gain dramatically, so a mitigated 1960s rambler often needs smaller equipment than an unsealed identical home on the same street. We verify mitigation status during our walkthrough and adjust the Manual J accordingly. Call (817) 402-2972 for a free estimate.
Both are possible. We install central air with new ductwork in many Burien ramblers, routing low-profile ducts through attics, closets, and soffits. If your floor plan is chopped up or you want zone control, ductless mini-splits avoid tearing into finished walls. We present both options with written prices and let you decide.
The previous contractor probably sized from the old unit’s nameplate without running a load calculation, or they missed that your home had received noise-mitigation sealing that lowered its heat gain. An undersized unit runs constantly without reaching setpoint. We measure everything and size to the house as it exists today, not as it was built in 1965.
Yes, always. Many Burien homes still have 100-amp panels or fused disconnects that can’t handle a modern condenser’s locked-rotor amperage. We inspect the panel during our site walkthrough and include any needed electrical upgrade in your written price, so there’s no surprise subcontractor visit after install day.
We check whether the system is actually failing or just fighting bad ductwork, an undersized install, or a hidden HRV tied into the return path. Through a job off SW 152nd St., our tech traced uneven cooling to a collapsed run of original 1960s 6-inch duct buried in the crawl space, and during the site walkthrough we also found an unlabeled Port of Seattle noise-mitigation HRV tucked in the attic that the homeowner had never serviced. We sealed and re-balanced the ductwork, sized a Carrier system with a proper load calculation rather than a like-for-like swap, and left the HRV operating independently of the new blower so the two wouldn’t fight each other. Call (817) 402-2972 if your Burien home isn’t cooling like it should.
