Maintenance

Bryan Orr The following list is the actual process we use at the company I own for our typical “standard” residential maintenance. I'm sure you will find some things you do differently. Take it for what it is, and I'm happy to get any feedback you may have. 1. Read the call notes, property notes, and customer notes. Check the last service call and last notes and readings so that you are aware of the service history. 2. Check the filter size and ensure you have the PROPER filter if possible. 3. Wear shoe covers in the home. 4. Ask the customer if they have noticed anything unusual with the system. 5. Inspect and set the thermostat to run. Shine a light in the return to check for filters, blockages, debris, or damage. 6. Visually inspect the system operation to make sure all of the components appear operational before beginning the maintenance. Note anything out of the ordinary you observe to the owner and address/diagnose before proceeding.
