Check if your HVAC contractor is overcharging

AC, furnace and heat pump replacements are some of the biggest checks homeowners write, and bids for the same house often differ by thousands. GenuineRate checks each line of your HVAC estimate against typical installed prices in your metro and flags what's missing — equipment specs, permits and warranty.

Common overcharges

No model numbers or efficiency ratings

An estimate should name the brand, model, size (tons or BTU) and efficiency (SEER2, HSPF2, AFUE). Without them you can't compare bids — or check what gets installed.

Oversized equipment

A bigger system costs more and often runs worse. Ask whether a Manual J load calculation was done to size it.

Refrigerant priced per pound far above market

Recharges are billed per pound. Ask how many pounds, and why the system lost refrigerant — a leak should be found, not just topped up.

Permit left out

Replacing an AC or furnace needs a permit in most places. A bid without one is cheaper on paper and riskier for you.

Big upfront deposit

Many states cap deposits on home-improvement work. Paying most of the price before installation leaves you with little leverage.

Frequently asked questions

How much does it cost to replace a central AC?

A 3-ton central AC with a new coil typically costs $5,000–$10,000 installed, depending on efficiency, brand and how much ductwork or electrical work is needed.

Should I replace the furnace and AC together?

If both are near the end of their life, replacing them together usually saves on labor and makes sure the indoor and outdoor parts are matched. A gas furnace alone typically runs $4,000–$8,000.

What should an HVAC estimate include?

Brand and model numbers, size, efficiency ratings, what's being replaced (condenser, coil, line set, thermostat), permit, removal of old equipment, labor warranty and the manufacturer's warranty registration.
