PROLOGUE Your HVAC system is one of the most important parts of your home. It keeps your family warm in the winter and cools in the summer, but if the system doesn’t receive routine inspections and maintenance, it won’t work efficiently. Prolonged lack of maintenance could result in costly repairs or the need for complete replacement.

Checklist to Inspect your

Indoor Unit

The indoor portion of your unit is comprised of many moving parts that need to work at their best to ensure the proper performance of the whole HVAC unit. Air Filters - Filters should be cleaned monthly and changed every three months to ensure they are not pulling dirt into the system. Blower Assembly - The blower assembly includes the blower wheel and blower motor and their housing. Keeping it clean ensures proper airflow in the home. Burner Assembly - Use a brush or a small vacuum attachment to clean and adjust the burner assembly if necessary. Clean Exterior - The unit’s shell should be clean. Combustible Material - Ensure there are no fire hazards near the indoor portion of your HVAC unit. Combustion Blower Housing  - The combustion blower housing can easily collect lint and other small debris and should be cleaned regularly.

Checklist to Inspect your

Outdoor Unit

The outdoor portion of your HVAC unit is just as important as the indoor portion. It should be inspected as often as the indoor section is. Base Pan - Check the base pan to ensure its drains do not have a blockage. Remove any debris or other obstructions if necessary. Cabinet - Remove any leaves or debris from your unit’s cabinet housing. Coils - Clean and remove leaves, twigs, and dirt from the coils. This will increase efficiency and longevity. Compressor and Tubing - The compressor and its tubing should not have any damage and should be operating within correct levels for amperage and volt draw. It should have functioning wire connections. Control Box - The control box’s wiring connectors and other components should have no damage and operate efficiently. This includes contractors, circuit boards and several other components you’l l see in the box.

Checklist to Inspect your

Outoor Unit

Fan Motor and Blades - Inspect the motor and blades for any wear or extensive damage. Just as the inside motor needs it, older outdoor motors will need lubrication. Check belt tension if necessary. Refrigerant - Your HVAC unit’s refrigerant should be operating with the proper pressure and should be at the correct level. Too much refrigerant is a waste, but too little means your system is not working as efficiently as it could be. Surrounding Area - Remove dirt, leaves, twigs, children’s toys and other dangerous lawn clutter from the immediate area surrounding your outdoor HVAC unit.
