  2. Compare equipment line by line. Match model numbers, efficiency ratings and warranty terms across quotes.
  3. Verify mechanical licensing. Iowa and several neighboring states license HVAC/mechanical work.
  4. Ask about rebates. A good contractor helps you claim utility rebates and tax credits.
  5. Get maintenance terms. Ask what tune-ups are included and what voids the warranty.

Red flags to watch for

  • Sizes the system by square footage alone
  • Pressures you to replace a system without a written diagnosis
  • Cannot provide model numbers in the quote
  • Will not register the equipment warranty for you
