Installation & Maintenance

How long do heat pumps really last? Drawing on DOE and EHPA service-life data, this guide sets realistic expectations for air source, ductless and ground source systems, explains the three factors that shorten lifespan - installation quality, coastal corrosion and skipped maintenance - decodes compressor and parts warranties, and provides a practical maintenance calendar. It closes with a repair-or-replace decision framework for buyers planning their next investment.
