Ideal maintenance for air conditioning systems should occur at least once annually. Before the cooling season starts, it is advised to have a competent HVAC expert do an annual AC maintenance check. Regular maintenance ensures that the system runs well, lowers the likelihood of breakdowns, and increases the equipment's lifespan. The technician will perform a thorough inspection and cleaning of the parts, check the refrigerant levels, lubricate any moving parts, and perform any necessary adjustments or repairs during the maintenance visit. Some homeowners might opt to have their air conditioners serviced twice a year, with a check for heat pump systems just before the heating season.
