[Optional] Furnace Filter Replacement Fee

[Optional but highly recommended]

HVAC professionals recommend changing furnace filters quarterly to extend a furnace's life. This can also serve as a quarterly inspection for your unit(s).

Labor is $25 for the first unit at a property plus $10 for each additional unit at the property.

Material is given at cost.

This is calculated using the following formula:

$25 + ((number of units at property -1) x $10) + materials
