A malfunctioning furnace can produce carbon monoxide, an odorless gas responsible for hundreds of deaths annually. Licensed HVAC technicians test for CO leaks, verify gas pressure, and ensure proper venting. Annual professional inspection is the single most important step for heating safety.

HVAC systems should be professionally serviced twice per year: once in spring for your cooling system and once in fall for heating. Change air filters every 1-3 months depending on usage, pets, and air quality. Regular maintenance extends system life by 5-10 years and reduces energy bills by 15-25%.
Consider replacement when your system is 15-20 years old, needs repairs costing more than 50% of a new system, uses R-22 refrigerant (phased out), or cannot maintain comfortable temperatures. New high-efficiency systems can reduce energy costs by 30-40% compared to units from the 2000s.
HVAC sizing requires a Manual J load calculation that accounts for your home's square footage, insulation, window area, orientation, climate zone, and occupancy. Oversized systems short-cycle (wasting energy and reducing comfort), while undersized systems run constantly. Always get a proper load calculation, not a rule-of-thumb estimate.
