All of our HVAC calculators are useful but serve different purposes. A good place to start is using our Repair or Replace Calculator. It recommends using a $3,000 threshold in conjunction with the system's age and warranty status to determine whether to repair or replace your HVAC system. From there, our HVAC Sizing Calculator helps you find the ideal system size for your home to ensure maximum efficiency and comfort. Our SEER Savings Calculator is coming soon. It will show you the potential savings from upgrading to a higher-SEER system and help you determine if the upgrade is worth it.
