Replacement Cost Estimator

1. Select your system type. Choose between a traditional AC and furnace combo, a heat pump, or a ductless mini-split system. Mini-splits are priced by the number of indoor zones.

2. Pick your efficiency level. Standard efficiency costs less upfront but more to operate. High-efficiency systems cost more to install but lower monthly energy bills and may qualify for federal tax credits.

3. Set the system size and your region. Tonnage should match your home's load calculation. Regional labor and material costs vary significantly, with the Southeast being most affordable and the West Coast being most expensive.

4. Adjust for home complexity and ductwork. Multi-story homes, attic installations, and crawlspaces add labor time. New ductwork can add 50% to the total project cost.

System type and efficiency. The biggest cost driver is the equipment itself. A basic 14 SEER air conditioner with an 80% furnace is the most affordable option. Heat pumps cost slightly less for the equipment but provide both heating and cooling. High-efficiency units (20 SEER / 98% AFUE) can cost double the standard models.

System size. Larger homes need larger systems. The cost scales roughly proportionally with tonnage. A 5-ton system costs significantly more than a 2-ton system in both equipment and labor.

Regional pricing. Labor rates, permit costs, and material availability vary by region. Southeastern states tend to have the lowest installation costs, while the West Coast and Northeast are the most expensive markets.

Home complexity. Multi-story homes require more refrigerant line, longer duct runs, and scaffolding or ladder work. Attic installations in hot climates add difficulty and time. Crawlspace work is physically demanding and slows the job down.

Ductwork condition. If your existing ductwork is in good shape, the contractor simply connects the new system. Partial modifications (adding a return, resizing a trunk line) add moderate cost. A full duct replacement is a major project that can increase the total price by 50%.

During sales visits. Pull this up on your tablet while sitting at the kitchen table with a homeowner. Walk through the options together, show them how efficiency level and ductwork condition affect the price, and set realistic expectations before running your detailed proposal.

Phone estimates. When a homeowner calls asking "how much for a new AC?" you can walk them through a few questions and give a ballpark range on the spot. This builds trust and qualifies the lead before scheduling an in-home visit.

Website lead generation. Embed this calculator on your website so homeowners can self-educate on pricing. Visitors who use the tool and then call you are better-informed and more likely to convert because they already have realistic price expectations.
