If you have allergy sufferers, older relatives, very young children or chronically ill people living with you, you recognize how serious and dangerous high temperatures can be. Cooling isn't always just a luxury; cool air can mean relief from symptoms and calmer, happier people in the house. Cooling failure is unwanted, therefore repeated cooling maintenance is smart. Complete these tasks.
Clearing Unit Area
Maintenance begins outdoors. Your main unit is probably behind the house, but it's easily reachable and if your family is like most, the unit is ignored. That's how dead leaves, insects and even soil can infiltrate the sitting unit. Avoid that; regularly clear surrounding land.
Wiping Fan Blades
Obstructions in fan blades can stop them altogether, and they really should be wiped clean periodically. First switch the appropriate circuit breaker so you won't fear or risk electrocution during this task. Remove the casing and brush away twigs or other debris and using clean, dry fabric or cloth, wipe blades.
The A/C unit's coils should not be dirty and ice should not be building up on them. If you see dirt or some ice on the coils, that isn't normal. Covered coils work motors harder and cleaning is vital. Brush soiled coils, but take care with ice. Don't scrape them; let the heat naturally defrost them and seek root problems like leaking refrigerant or poor circulation.
Clean filters mean good air quality. Blocked filters mean dirtier air flow, overworked motors and ultimately, big problems. Know where the filter is and know what filters look like so purchasing replacements is simple. Having extras will enable you to rapidly replace ripped or very dirty pieces.
Tightening All Screws
Often forgotten, loose screws will worry you with thoughts that inner components are broken. Every few months, look for unit screws and get the screwdriver out to tighten them.
Reading the Manual
Reading isn't innately a maintenance task, but for HVAC-related care, the manual should be the first stop. The manufacturer bests knows what components must be monitored, changed and replaced and, through the manual, suggests timetables you can follow. If you've never come across the manual, it's possible that your installer didn't provide one. The manufacturer's site will oftentimes have a viewable one.
Your entire family has an interest in keeping air cool. Enlist them to assist you in remembering these tasks and carrying them out. Your A/C or HVAC contractor will provide expert eyes for anything suspected to be amiss.
