There could be several reasons for this. Common issues include dirty or clogged air filters, low refrigerant levels, blocked condenser units, or thermostat problems. In some cases, it could also be due to ductwork leaks or a faulty compressor. It's best to have a professional technician inspect the system to pinpoint the exact cause and fix it quickly.

Signs that you may need to rewire your home include frequent electrical problems, such as blown fuses or tripped breakers, outdated wiring kinds discolored outlets, or a burning smell near outlets or switches.

To keep your bills low, set your thermostat to a comfortable but efficient temperature (around 24°C in summer), use ceiling fans to help circulate cool air, and keep blinds or curtains closed during hot days. Also, regular maintenance like cleaning filters and checking for air leaks in doors or windows can make your AC work more efficiently and use less power.

If your AC is over 10–15 years old, needs frequent or expensive repairs, makes unusual noises, or struggles to cool your space, it may be time for a replacement. Modern units are more energy-efficient, quieter, and better for the environment. Upgrading can save you money in the long run through lower energy bills and fewer repair costs.
