2. Your Air Filter Is CriticalFilters protect your lungs and your equipment.
Change them every 60–90 days.
3. HVAC Systems Need Yearly MaintenanceTwo tune-ups per year:
4. Energy Efficiency Saves MoneyLook for:
5. Proper Sizing MattersOversized or undersized HVAC systems cause:
6. Ductwork Determines 30–40% of EfficiencyLeaky ducts waste conditioned air.
Sealing or replacing ducts often improves comfort instantly.
7. Smart Thermostats Improve ComfortNEST, Ecobee, and Honeywell smart thermostats reduce energy usage and automate temperature control.
8. Heat Pumps Are Becoming More PopularHeat pumps provide both heating and cooling and are highly efficient, even in cold climates with a backup furnace.
9. Humidity Control Is Part of HVACProper humidity reduces:
10. HVAC Technology Has ImprovedToday’s systems include:
11. Old HVAC Systems Waste EnergySystems over 15 years old can cost 20–40% more to operate.
