The answer to 'how to fix preventive maintenance' is to perform regular HVAC maintenance tasks to keep your system running efficiently and prevent costly breakdowns. This includes tasks like changing air filters, cleaning the condenser coil, and inspecting electrical components.
Preventive maintenance should be done at least once a year, ideally in the spring before the cooling season starts. Doing this regular maintenance can extend the life of your HVAC system, improve indoor air quality, and save you money on energy bills.
