HVAC replacement cost quotes can vary by thousands for identical jobs. Here's what a legitimate quote must include.
What Must Be Included
Equipment cost (brand, model, efficiency rating), labor, disposal of old system, permit fees, and required electrical or gas line modifications.
What's Often Hidden
- Permit fees: $100–$300
- Refrigerant: $50–$150
- Condensate drain work, thermostat wiring, ductwork modifications
These can turn a $4,000 quote into a $6,000 bill. Always ask: 'Is this all-inclusive?'
Efficiency and Price Impact
A 20 SEER unit costs more upfront but saves $200–$400/year, reaching payback in 4–8 years.
The Load Calculation
A contractor quoting without a Manual J load calculation is guessing at equipment size. Proper sizing is worth paying for.
