Preventative Maintenance

Regular maintenance is essential to keep your heating and cooling system running efficiently and to prevent costly repairs. At Duncan Heating and Air Services, we offer options to come twice yearly in the spring and fall to check your system and ensure it's running at its peak performance. In between those checkups, there are three key steps you can take to prolong the life of your unit and help it run efficiently:

  • Replace your filter every 30 days (every 15 days if you have animals)
  • Pour two capfuls of bleach into the drain line every month during the cooling season to prevent water leaks and system shutdowns
  • Use a water hose to rinse out the coil on your outdoor unit every few months
