Why such a wide price range?

A/C installations are affected by several price factors, including:

  • Unit size:

    Different sized A/C units are designed to work for different sized homes. The higher the size or "tonnage" of a unit, the higher the cost.
  • Unit efficiency:

    A/C units vary by their efficiency to cool your home. This efficiency score is known as a SEER rating. Higher SEER ratings come with higher prices.
  • Unit add-ons:

    Thermostat upgrades, air purifiers and other add-ons deliver extra convenience and comfort for a higher price tag.

Celebrating 85+ years of service in the great state of Michigan

Amazing service!”

"Our a/c had a bad leak that also leaked into the furnace. We contacted Thornton & Grooms and a representative came out the same day and after a great conversation, we had installers here the next day! Amazing service! Better still, Ahmed and the install team did an extremely neat and efficient job, thoroughly explained their work, and kept me in the loop of their progress. An unfortunate home concern has turned into a fantastic experience - bravo to the Thornton & Grooms team!"
