A well-maintained air conditioner uses noticeably less energy in heating mode and delivers more reliable performance than a neglected unit.
Air conditioners are not just essential in summer. They can also be a valuable heating source in winter. That said, careful maintenance is fundamental to keeping them efficient and keeping energy costs down. Here is how to look after your air conditioner during the colder months.
Why does maintenance matter?
A dirty or poorly performing air conditioner uses more energy and delivers less. Regular maintenance ensures:
- Higher energy efficiency: reduces the effort the system needs to heat a room
- Better air quality: prevents dust and allergens from building up in filters
- Longer device lifespan: proper care prevents costly breakdowns
- Filter cleaning: the first step towards savings
Filters are one of the most important components because they trap dust and particles from the air. To keep them clean:
- Remove them and rinse under warm running water
- Let them dry completely before putting them back
- Replace with compatible filters if damaged
- Recommended products for effective cleaning
For a deeper clean, use a dedicated product like Zep Foaming Coil Cleaner. It removes grease, dust and residue without damaging surfaces, leaving the unit perfectly hygienised.
Disinfecting the air conditioner
Beyond cleaning, disinfecting the unit is important for eliminating bacteria and unpleasant smells. Zep Zepynamic is ideal for this. Simply apply it to the ventilation grilles for an antibacterial action that keeps the air fresh and clean.
Periodic maintenance: what to do and when
To keep the air conditioner efficient all year:
- Every 3 months, check and clean the filters
- Once a year, have a qualified technician inspect the unit to check refrigerant levels and the condition of internal components
- Before winter, carry out a deep clean to prepare the system for seasonal use
Golden rules for saving energy
Beyond maintenance, these practical tips help optimise air conditioner use:
- Set the right temperature: keep it at 20 to 22 °C to avoid waste
- Use inverter mode: this technology automatically adjusts output to match demand, cutting consumption
- Seal doors and windows: prevent heat loss that forces the unit to work harder
- Switch off the unit when it is not needed: use a programmable thermostat to schedule when it runs
Good maintenance saves you money
A well-maintained air conditioner not only keeps you comfortable in winter but also delivers real savings on energy costs. Investing in quality products like Zep Foaming Coil Cleaner and Zep Zepynamic is an important step in preserving the efficiency of your system.
