- Get a Smart Thermostat. A smart thermostat will learn about your HVAC system and how to operate it more efficiently.
- Install a Dehumidifier.
- Replace Your HVAC System.

80% furnaces use type B vent and 90% furnaces use PVC pipe for venting material. Why do gas furnace efficiencies jump from 80% to 90%? Efficiencies over 80% cause condensation but the flue gas is still too hot for PVC vent pipe until the efficiency reaches 90%.
Should I oversize my furnace?
