AfterHVAC Company in SeaTac, WA
Most SeaTac homes aren’t built like their neighbors in Burien or Tukwila. Thousands were retrofitted through the Port of Seattle’s Residential Sound Insulation program with tightly sealed envelopes and mechanical ventilation systems that change how we approach every heating and cooling job. We’re Brandt HVAC, and we serve SeaTac with technicians who understand those RSI-era systems, backed by the Threshold Verified standard: you’ll know exactly who is coming to your door, by name and photo, before they arrive. Call us at (984) 538-9003 when you need AC repair, furnace repair, or AC maintenance in SeaTac.
Why SeaTac Homes Are Different
SeaTac sits in the Puget Sound marine zone where persistent winter dampness and modest temperature swings once made central air conditioning a rarity. But the airport noise mitigation program changed the physics of these homes. Starting in the 1990s, the Port of Seattle’s RSI program sealed thousands of houses in the 65+ DNL noise contour, adding acoustically-lined ductwork and mechanical ventilation units, typically energy recovery ventilators or heat recovery ventilators, to compensate for airtight construction.
The housing stock itself is mostly post-WWII tract homes and small multi-family buildings from the 1950s through the 1980s. The mechanical systems inside often don’t match the original build era. We’ve found mismatched ductwork, added ventilation runs, and non-original air handlers tucked into attics and crawl spaces that were never designed for them. The tight envelopes trap humidity and accelerate mold growth in ductwork, pushing demand for HRV and ERV maintenance well above what we see in other Puget Sound markets.
Homes in the inner noise contour, roughly the streets closest to the runways on the east and west sides, received the earliest retrofits. Their original Port-installed HRVs are now 25 to 30 years old and frequently fail in winter. Homeowners sometimes don’t know the units exist or who services them. That’s a call pattern we’ve learned to recognize and resolve.
Our Main SeaTac Services
SeaTac homeowners call us most often for cooling repairs in summer, heating repairs in winter, and preventive maintenance before each season turns. Each service has its own dedicated page with full details.
AC Repair in SeaTac
AC repair in SeaTac runs from failed capacitors and refrigerant leaks to compressor replacements on systems that work harder than their original design intended. The sealed building envelopes from RSI retrofits mean indoor heat builds faster and lingers longer when the cooling system goes down. We stock common parts for Rheem, York, Daikin, and Bryant systems locally, and most repairs finish same day. AC Repair in SeaTac covers what we fix, what it costs, and how fast we can get there.
Furnace Repair in SeaTac
Furnace repair in SeaTac includes standard gas furnace work plus the added layer of integrated HRV and ERV systems that share ductwork and controls. When a homeowner calls with “no heat,” the fault sometimes lies in the ventilation unit, not the furnace itself. We diagnose the whole system, explain what we find in plain language, and give you a written price before any work starts. Furnace Repair in SeaTac has full pricing and response details.
AC Maintenance in SeaTac
AC maintenance in SeaTac means more than a standard tune-up when your home has added ventilation equipment sharing the duct network. We clean coils, check refrigerant levels, test electrical components, and inspect the ERV or HRV for filter condition, damper operation, and balanced airflow. Catching a failing ventilation motor in spring beats discovering it on the first hot day. AC Maintenance in SeaTac explains what’s included and why it matters for RSI-era homes.

FAQs About HVAC Company in SeaTac
Most SeaTac repair calls receive same-day response, and no-heat or no-cooling emergencies during extreme weather get prioritized. Our phones are answered by a live person 24 hours a day, 7 days a week, so you never wait in a callback queue. Call (984) 538-9003 and we’ll give you a real arrival window.
Permit requirements depend on the scope. Most repairs and maintenance don’t require permits, but equipment replacements and duct modifications typically do. We handle permit paperwork as part of any installation job and coordinate with King County on inspections when needed. Ask us during your estimate and we’ll tell you exactly what applies to your project.
We do. The original HRV or ERV units from the 1990s RSI retrofits are now well past typical service life, and many homeowners don’t realize they’re responsible for maintenance after the Port’s warranty period ended. We diagnose, repair, and replace these systems, and we’ll show you where the unit is and how to check its filter during our visit. Call (984) 538-9003 for a free estimate.
