Replace your air filters: Air filters work overtime in the winter, so be sure to replace your filters. Dirty air filters make your HVAC system work harder than it needs to. This puts strain on the system, which can cause bigger issues and lead to higher utility bills.
Check and clear your unit’s drainage line: Most HVAC units have a drainage line at the base of the cabinet. In order for the unit to run properly, the hole needs to be clear. To make sure the drainage line works properly, use a paper clip or a wire to ensure the hole is clear of any obstructions.
Check your ductwork for issues: Your home’s ductwork, or ventilation system, can often be the cause of poorly distributed air, which means you’re spending more money on cool air that isn’t making its way into your house. Check for leaky connections and return vents, damaged or fallen insulation, and ensure your vents (both incoming and outgoing) are not blocked or obstructed by rugs or furnishings.
Test your unit: Turn on your AC and let in run briefly to see how it performs. If there are any problems, address them right away.
Make sure you conduct these tests before temperatures hit their peak.
