As summer is quickly approaching, it’s important to make sure your AC unit is prepared for frequent use. Hiring a professional HVAC technician to perform seasonal AC maintenance helps you ensure that your unit is in working, efficient order.
In addition to an AC unit tune-up, the following are other ways you can get ready for the summer heat:
- Change filters – It is considered one of the easiest things you can do to make your AC unit run smoothly. If you have a central air system, the filter is typically behind the metal panel, located behind the face of the blower unit. If you have a window unit or two, the filter is on the face of the unit, located behind a metal or plastic panel.
- Clear debris – If you have an outside unit, remove any leaves, plants, or debris that’s blocking your unit. You should check your unit debris at least once a month.
- Clean condenser coils – If you don’t have a cover for your outside unit, your outside unit may have been accumulated leaves, dirt and debris all winter long. In order to clean the coils, you must turn off your unit, then remove the protective grilles from the unit using a screwdriver or nut driver. By using a refrigerator coil brush or soft brush on a vacuum, you can delicately clean the coils without bending the fines or damaging the coils. For more unyielding debris, use a hose wot blast dirt and debris out of the coils, but be wary of flooding the unit or getting electrical components wet. Or you can use commercial coil cleaner, but be careful not to spray the fan or electrical components.
- Inspect ductwork for leaks – Look for any minor holes, separated pieces or disconnected joints. All of the seams and connections should be sealed. If you discover any holes or exposed joints, use silver aluminum-foil tape instead of duct tape for better, long-lasting results.
- Check coolant lines – The refrigerant pipes which run from the evaporator on the air handler to the condenser outside are usually protected with foam coolant line insulation. If you notice the insulation is frayed or missing, replace it by installing foam insulation sleeves or wrap the lines with foam insulation tape like a spiral.
