• Take Advantage of Local Utility Rebates: Check for rebates offered by SRP or APS for high-efficiency hybrid heat pump systems.
• Schedule Pre-Failure Upgrades: Replacing your unit before it bursts gives you time to comparison-shop rather than paying emergency dispatch fees.
• Perform Regular Maintenance: Regular flushing removes mineral deposits, protecting heating elements and maintaining high operating efficiency.
