Equipment Costs
This covers the air conditioner, furnace, heat pump, or other main equipment. Model numbers should be listed—look them up to verify specifications.
Installation Labor
Labor for removal of old equipment, installation of new, ductwork modifications, and electrical work. Complex installations cost more.
Materials and Supplies
Refrigerant lines, electrical components, drain lines, pads, and consumables. These should be itemized, not lumped into labor.
Permits and Inspections
Professional installations require permits ($100-$300+) and inspections. Contractors who skip permits are cutting corners—and breaking the law.
Warranties and Guarantees
Equipment warranties, labor warranties, and satisfaction guarantees. Extended warranties have value but also cost—evaluate based on your risk tolerance.
Optional Items
Upgraded thermostats, air purifiers, duct cleaning, or maintenance plans. Evaluate these separately—don't let them obscure base pricing.
