With the warmer summer weather coming you want to be certain your AC unit is in top operating condition. You certainly don’t want your AC to fail during the hottest part of the year and that’s why preventative rooftop AC unit maintenance is so important. Hiring an experienced professional to assist with your seasonal AC maintenance also ensures that the job is done correctly.
When reviewing rooftop unit maintenance schedules, the following service items are of the utmost importance.
An Inspection Checklist for Your Rooftop AC Unit
- Check the Filters and Screens: Regular filter changes are a common AC service item and one that is essential for good indoor air quality. Filters should be inspected, cleaned of debris and, if needed, replaced. Any screens in your AC system should also be cleaned as needed.
- Inspect the Fan Blades and Belts: A broken fan can damage your AC unit and also renders it inoperable. The fan blades should be cleaned, in good condition, and correctly centered in their housing. Look for issues such as wearing, cracks and chipping. Also, be sure to check the fan belts for any damage and replace them yearly to avoid issues such as sudden snaps.
- Inspect the Heating Components and Systems: Even with the weather warming up, the heating system should still be carefully inspected and serviced. Items to look for include rust or cracks, as this can make the system unsafe. Other components to check include the burner and the igniter, and be sure to check the pressure and look for leaks.
- Clean the Coils: Much like a home AC unit, your rooftop unit also should have its coils cleaned. Dirty coils negatively impact performance and can increase cooling costs and stress your AC.
- Check the Refrigerant: Run your unit for about 15 minutes and check the refrigerant charge. Any odd readings or sudden jumps can indicate your refrigerant levels are low or leaks have developed in your AC.
- Check the Drainage System: Check your drainage system and any associated components such as drainage pans. Proper drainage prevents moisture collection and protects your AC unit and roof from water damage.
- Look For Electrical Issues: Finally, check the electrical system for any issues by testing the voltage and amperage levels. Issues with these readings can indicate repair needs such as damaged wiring.
Final Thoughts
Regular maintenance is an essential step in keeping your rooftop AC unit running as expected and delivering the levels of performance you expect. A professional inspection this spring gets you ready for the coming warm weather and the hotter summer to come.
