3 Things to Know Before You Call a Contractor
1. Get 3 quotes minimum. HVAC pricing varies 30-50% between contractors for the same equipment. A second opinion is not optional.
2. Ask for the model number, not just the brand. “Carrier furnace” could mean a $4,500 base model or a $9,000 premium unit. The model number tells you exactly what you are getting.
3. Confirm the quote includes everything. Permits, ductwork modifications, electrical upgrades, thermostat, and disposal of old equipment should all be in writing. See common hidden costs →
