To prepare your HVAC system for a vacation home during non-occupancy, you should adjust the thermostat, clean filters, and ensure a power supply is maintained for necessary functions. Regular professional check-ups are also vital to catch potential problems early.
Adjust the Thermostat
Setting your thermostat wisely is crucial when leaving a vacation home. In colder months, set the thermostat to around 10-12°C to prevent pipes from freezing. For warmer periods, a setting of about 26-28°C helps avoid excess humidity and mold.
Proper thermostat settings can prevent costly damages and maintain air quality when the home is unoccupied.

Clean and Replace Filters
Before leaving, always clean or replace the HVAC filters. Dirty filters can cause the system to work harder, leading to wear and potential breakdowns. Regular maintenance also supports better air quality when you return.
Ensure Power Supply to the System
Your HVAC system should remain powered for essential functions, such as dehumidification or anti-freeze measures. However, ensure unnecessary devices are unplugged to save energy and reduce risk.
Schedule Professional Inspections
Routine check-ups by a professional can identify issues that might worsen over time. Consider contacting an HVAC contractor in your area, like those in Toronto or Montreal, to ensure your system is in top shape before leaving.
Seal Windows and Doors
Prevent drafts and energy loss by sealing windows and doors. This helps maintain the indoor temperature with less effort from your HVAC system, avoiding unnecessary strain and costs.
Consider a Smart Thermostat
Installing a smart thermostat allows you to monitor and adjust your home’s temperature remotely. This can be particularly useful in managing unexpected weather changes and optimizing energy use while you’re away.
By following these steps, you can safeguard your vacation home’s HVAC system during periods of non-occupancy. This ensures comfort and reduces potential repair costs when you next visit.
