2026.01.01 - Beat the Summer Rush: Why Now is the Best Time for AC Maintenance
Happy New Year!
As the temperature drops in Hong Kong, the last thing on most people's minds is their air conditioning. We've found that the "off-season" is actually the smartest time to handle your AC maintenance.
By booking your check-up and professional cleaning during the cold weather, you can take advantage of:
Lower Costs: Many contractors offer better rates when demand is low.
Easier Booking: You won't have to compete with the mid-July rush when technicians are fully booked for weeks.
Peace of Mind: You''ll be ready for the first heatwave without worrying about mold or malfunctions.
A Wake-Up Call: The "Invisible" Office Hazard
To illustrate why this matters, we want to share a recent case involving one of our office space tenants. They had noticed the air felt "heavy" and staff were complaining of fatigue and respiratory irritation.
Upon investigation, we discovered a perfect storm of pollutants. The air quality was being compromised by several factors:
Neglected Maintenance: The AC units hadn't been professionally cleaned in years.
Specific Pollutants: Off-gassing from printers, new carpets, and furniture (common sources of VOCs).
Unique Factors: Dust and organic particles from an adjacent Chinese tea storage area.
Lack of Filtration: The existing setup didn't have enough air filters to handle the volume of pollutants.
The Data: A Drastic Transformation
We tracked the indoor air quality (IAQ) throughout the intervention process. The results highlight how critical professional AC cleaning is compared to other measures.
Why AC Cleaning Was the Final Piece
While adding filters and improving ventilation (the 15-minute rule) brought the numbers down significantly, the air quality didn't reach "excellent" levels until the AC units were professionally cleaned. Over time, AC coils and fans become breeding grounds for mold and traps for the very pollutants (like printer toner and tea dust) mentioned above. When you turn the unit on, it simply recirculates these toxins.
Our Recommendations
Don't Wait for Summer: Contact a technician this month while they have immediate availability.
The 15/2 Rule: Even in winter, try to open your windows for 15 minutes twice a day to flush out TVOCs from furniture and electronics.
Check Your Filters: Ensure your air purifiers are rated for the size of your space and that filters are replaced according to the manufacturer's schedule.
