Deer Valley
Pre-winter clean + sanitize fog
5,800 sq ft second home — opened Thanksgiving with 9-month-stale system. Full clean + EPA fog cleared musty odor before family arrival.
Park City second-home specialists. Pre-arrival open-up packages, post-departure deep-clean packages. Coordinate with property managers and concierges.
Park City elevation (7,000+ ft) creates extreme dryness 9 months/year. Combined with second-home occupancy patterns (closed for 9-10 months), Park City HVAC develops musty-stale odors that humidify-ventilation cycles cannot clear without sanitizing.
Second-home density is ~50% — units sit closed for 9–10 months and accumulate musty HVAC odor that sanitizing fog clears.

Why This Microclimate Matters for Park City HVAC
High-elevation extreme dryness 9 months/year + closed second-home occupancy patterns create a unique "stale system at season open" syndrome. UV-C + sanitizing fog packages dominate Park City service mix.
Each construction era has its own typical duct issues. We adjust our process to match the housing.

Tips tied to Park City's specific climate, housing era, and dust profile. Not generic advice.
Pre-arrival open-up cleaning + sanitize fog before season open — clears 9-10 month stale-system odor.
Whole-home humidifier maintenance is critical — Park City winter RH drops below 10%.
Annual UV-C bulb replacement is mandatory at altitude — UV degrades faster in extreme dryness.
Multi-zone custom HVAC: each zone needs its own service cadence.
Combine duct + sanitize fog + UV-C for second-home season open — single trip from SLC.
