Why do gas furnace efficiencies jump from 80% to 90%?
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%.
Are furnaces always gas?

Should you replace your furnace and AC at the same time?
In most cases, it’s a good idea to replace the furnace at the same time as the air conditioner. The new air conditioning unit has increased efficiency, with SEER over 16. If your furnace is old (15 years old or more), it won’t contribute to the efficiency of the HVAC system, making the AC unit an impractical expense.
