Frequently asked questions
How long does a furnace last?
A well-maintained furnace typically lasts 15-20 years before replacement makes financial sense.
Should I replace the furnace and AC together?
If both are aging, replacing together saves on labor and ensures the system is matched - often $5,000-$15,000 combined.
Does a high-efficiency furnace pay off?
In colder climates the fuel savings usually justify the higher upfront cost within several heating seasons.
