If you have an older system or use your AC heavily, you may benefit from twice-yearly checkups to prevent wear and tear.
During an AC maintenance visit, technicians inspect and tune up your system by cleaning or replacing air filters, checking and adjusting refrigerant levels, tightening electrical connections, lubricating moving parts, cleaning coils and the condensate drain, and testing the thermostat.
This helps identify potential issues early and ensures optimal efficiency.
Yes, preventive maintenance helps improve your system’s efficiency, which can lead to lower energy consumption. A clean and well-maintained system doesn’t have to work as hard to cool your home, which reduces strain and energy use.
Even small improvements in efficiency can lead to noticeable savings on your utility bills over time.
