Restricted airflow can increase energy use and strain forced-air equipment.
Open DIY guideA pre-season inspection can catch combustion, venting, electrical and airflow problems before sustained cold weather.
Open DIY guideElectrical connections, heat strips, blower components and airflow still need periodic inspection even without combustion.
Open DIY guideBoilers rely on safe pressure, controls, pumps and venting or electrical components that should be checked before winter.
Open DIY guideHeat pumps work through both heating and cooling seasons, so a fall operating check can catch problems before cold weather.
Open DIY guideA spring check can identify airflow, drainage, electrical and outdoor-unit problems before heavy cooling use.
Open DIY guideA controlled seasonal startup helps identify leaks, mineral buildup, worn pads, airflow problems and water-distribution issues before regular evaporative-cooling use.
Open DIY guideWater left in an exposed cooler or supply line can freeze and cause damage.
Open DIY guideA controlled seasonal inspection helps find broken heads, leaks, poor coverage and misdirected spray before regular irrigation use.
Open DIY guideTrapped water can freeze in irrigation piping, valves and backflow components.
Open DIY guideA sump pump is most useful only if the float, discharge path and power source work before heavy moisture reaches the pit.
Open DIY guideRoof runoff, poor grading, ponding and blocked drainage can direct water toward the foundation or crawlspace.
