Arrived onsite to swap out air handler filters. Homeowner provided me aprilaire 310, and aprilaire 213, and a 14x30x1. First, there are two air handlers that only require filters in the Spring Maintenance. Homeowner has a boiler with baseboard for heating season and no filters needed for heating season. Found in air handlers and aprilaire 310 and a 20x25x4 box filter. The homeowners aprilaire 213 is not the right size and the 14x30x1 is a no longer used size. Took the 213 filter and promised to supply 20x25x4 filter for Spring 2025. Filters size are Aprilaire 310 and 20x25x4 box; customer will supply in Spring 2026.
