Basics

This page aims to go over the various forms of Preventative Maintenance for HVAC Systems
Design for Cleaning in terms of overall design of the HVAC system is a HIGHLY relevant matter, but will be addressed on another page

List

Every so often both the Condenser Coil and the Evaporator Coil should be cleaned
This is best done by:
- 1.) [LOTO]] on the Machine
  - If a Soft Starter is not installed, it is also best practice to turn down/off the Thermostat so that the system doesn’t go “from zero to 60” when you reconnect it
- 2.) Remove Debris as best you can while it is still dry
  - A Vacuum Cleaner (+ Dusting Brush Tool / Crevice Tool ) and/or some sort of Cleaning Brush and/or a Cordless Air Duster will come in handy for this
- Check Warranry / Manufacturer Warnings First + Proceed with Caution, BUT:
- 3.) Gently Rinse with Water
  - If sufficient one can stop here, if it looks like further cleaning is needed:
- 4.) Spray Down with a Gentle Cleaning Solution / Gentle Soap such as “Simple Green” or A Diluted Minimum Viable Soap
- 5.) Rinse + Inspect
  - If sufficient, one can stop here, if it looks like it still needs further cleaning:
- 6.) Get HVAC Coil Cleaner either in Aerosol Can form, or as a Liquid Concentrate which can be diluted + put into a Foam Cannon Nozzle
- 7.) Final Rinse with Water
- 8.) Gently Dry Off / Wait for it to Air Dry
- 9.) Reassemble Device
- 10.) Undo the LOTO then Turn it back on and check that everything is operating as expected
