Installation
Your HVAC system is only as good as the HVAC technician who installed it. Improper furnace installation can reduce the unit’s lifespan. Make sure you research the company before you hire. Look at online reviews, get referrals from friends and family and understand the warranties included with the installation.
Location
Location can have a significant impact on the lifespan of your furnace. Furnaces in crawlspaces generally have a much lower lifespan than a furnace in the garage, for example. In a crawlspace, the furnace contends with outdoor temperatures and pests. Furnaces in attics tend to have a shorter lifespan as well.
Thermostat Settings
