Before you sign a quote in Maryland

  • Ask for the load calculation. The size should come from a room-by-room calculation (called a Manual J), not the size of the old unit.
  • Ask what's included. Equipment, labor, permit, removal of the old unit and the startup readings, each named. Six questions worth asking.
  • Ask about the permit. Most towns require one for a replacement, not only a first install. Why it matters.
  • Read the model numbers. They say what you are actually being sold. How to read them.

Where do these numbers come from?

From 6 real quotes homeowners in Maryland received, dated June 2026 to October 2026, either shared through our Quote X-Ray or published openly by the homeowner. Cost-model estimates never count, and a state gets a page only once it holds 5 full-system quotes.

How to read these numbers

  • These are quotes, what a contractor proposed, not final invoices. Scope varies: some include ductwork, a thermostat or a permit and some don't.
  • The middle price is the median: half the quotes were lower and half higher. It moves less than an average when one quote is unusually high.
  • 6 quotes is a real sample, not a survey of the state. Prices differ across a state, and one city can sit well above or below this.
  • The quotes are dated from June 2026 to October 2026. The page updates as new quotes arrive.
