Why are HVAC replacement quotes so expensive?
HVAC technicians often quote thousands of dollars for new furnaces and air conditioning units—sometimes reaching up to 19k—leaving homeowners scrambling to afford it or considering risky DIY fixes. Lacking cash and unsure what pricing is actually reasonable, people feel vulnerable to overpaying when their heating or cooling systems fail.
