What Every Plano Resident Should Know Before Scheduling Service
- Replace a gas furnace with another gas furnace, or switch to a heat pump?
- Stay with gas if your winter design temp is below 0°F and you have cheap natural gas — heat pumps still derate in extreme cold. Switch to a heat pump if winters are mild AND electricity isn't 2× the national rate AND a state rebate stacks. Run 10-year operating costs, not just install price.
- What AFUE rating should I look for in a new gas furnace?
- 95–98% AFUE for cold climates (condensing furnace; requires PVC venting and a condensate drain). 80% AFUE is acceptable in mild climates where the high-efficiency install premium doesn't pay back. Skip the 92–94% band — the price-to-efficiency curve is bad there.
