Frequently Asked Questions

  • Can I do basic maintenance on my air conditioner myself?

    Yes, there are a few simple tasks you can do at home, like cleaning or replacing filters every few months, checking outdoor units for obstructions, and ensuring vents are unblocked. However, more detailed inspections, gas checks, and electrical servicing should always be left to qualified technicians to ensure safety and preserve your system warranty.

  • Why is my split system air conditioner not cooling properly?

    If a split system isn’t cooling effectively, it could be due to dirty filters, low refrigerant levels, a blocked outdoor unit, or a faulty thermostat. Sometimes, the issue might be electrical or linked to a worn-out compressor. Regular servicing helps identify these issues early. It's important not to ignore performance drops, as running a malfunctioning system can increase energy bills and cause long-term damage.

  • What happens during a home air conditioner maintenance service?

    A professional air conditioner service typically includes cleaning the filters, inspecting and cleaning coils, checking refrigerant levels, flushing drain lines, testing thermostats, and ensuring all components are functioning safely and efficiently. This process helps maintain indoor air quality, reduce running costs, and extend the lifespan of the unit. Most technicians also look for early signs of wear to prevent future breakdowns.
