Factors That Affect AC Lifespan​

Regular Maintenance​

Proper Sizing​

Proper sizing is critical when installing a new system. An oversized unit may cycle on and off too often, while an undersized unit will run constantly trying to keep up with demand.
Both situations create unnecessary strain on the equipment and can shorten the lifespan of your HVAC system.
