When temperatures drop and your air conditioner stops running daily, that's the ideal window for end-of-season maintenance. Switching it off and leaving it untouched until next summer is a mistake: a unit that isn't properly prepared loses efficiency over winter and is more likely to cause problems when you need it again. A couple of hours now protects the lifespan of your system and the air quality in your home.
Start with a thorough cleaning of the indoor filters. Through the summer months, they collect dust, pollen, and fine particles. Left in place, these deposits reduce performance and circulate allergens through your rooms.
A product like the Zep foaming sanitising cleaner works well here: it kills bacteria, neutralises bad odours, and leaves surfaces clean and fresh.
Next, turn your attention to the outdoor unit. Rain, wind, and dust leave behind debris that blocks airflow. Clean it with compressed air or a dry cloth, and clear away any leaves or dirt around it. If you're in an area with harsh winters, a breathable cover can keep moisture from building up inside the unit during the colder months.
Check the drainage system too: blockages or scale in the drain lines cause standing water and unpleasant smells. Finally, have a qualified technician verify the refrigerant level and inspect the electrical components, so you can start next season with confidence.
End-of-season maintenance is an investment in your unit's longevity and your home's health. With the right products like the Zep sanitiser, you avoid expensive repairs and get clean, fresh air the moment you switch it back on.
