Bid Fairness Checker

HVAC bid fairness checker.

An air conditioning quote is really an equipment quote with labor attached, which is why two bids for the same house can land thousands apart. In 2026 the fair national band for a central hvac system (gas) runs $9,837 to $12,178, built on $8,788 of real delivery cost. Paste the bid and see which side of that line yours falls on, sized to your tonnage and your metro's wages.

Fair range. Break-even sits at the red line: the cost of delivering the job, not a price anyone should demand. The green band above it is fair territory: most solid bids land at a 15 to 22 percent margin on the bid, roughly 18 to 28 percent over the cost to deliver, leaner or richer by trade and market. That band is earned money. No one works for free, and if the job were easy you would not be hiring it out.

How the Verdict Works

Built, not guessed.

The checker rebuilds the job from primary data: Craftsman hours at your metro's loaded BLS wage, FRED PPI materials, the verified permit fee, and NAHB overhead. That sum is the cost to deliver. A fair bid sits 8 to 14 percent over it at the lean floor and 24 to 45 percent at the premium ceiling, scaled by your trade and metro. Read the full methodology.

FAQ

Bid checker questions.

What is a fair price for central hvac system (gas)?+
In 2026, a fair central hvac system (gas) bid runs $9,837 to $12,178 nationally. The cost to deliver sits at $8,788, and an honest margin lands roughly 12 to 39 percent above it depending on the metro.
What does the checker compare my bid against?+
Every benchmark is built, not scraped: Craftsman labor hours times BLS metro wages with burden, FRED PPI-adjusted materials, verified city permit fees, and NAHB overhead. The verdict places your number on a ladder from below cost to premium against the fair band for your metro.
Is a bid far below the cost to deliver a good deal?+
Usually the opposite. A bid below the cost to deliver means someone is cutting scope, insurance, or quality to get there, and the checker flags it as below cost rather than calling it a bargain.
Why should the contractor make a profit on top of the cost to deliver?+
Because nobody works for free. Cost to deliver is the break-even: labor, materials, permits, and overhead with zero profit in it. The 18 to 28 percent most contractors keep over that, a 15 to 22 percent margin on the bid, pays for the license, the insurance, the warranty callback, and the judgment you are actually hiring. If the job were easy, you would not need a contractor at all. Use the floor to spot padding, not to demand free work.
Why do HVAC bids vary so much for the same house?+
Equipment tier does the most damage: a builder-grade condenser and a premium variable-speed unit can differ by thousands before anyone touches labor. The checker prices the work at your tonnage from Craftsman hours and BLS wages, so the equipment story has to stand on its own.
