See What Our Customers Say

  • I feel I could say a great deal more but the best advice I can offer is to contact or hire Cottam Heating & Air Conditioning inc

    Art Glauberman
  • Michael thank you for all your help, and might I add patience, in working with me to ensure my family had heat and hot water.

    Nat Fields
  • Very professional. Their prices are more than competitive. We had gotten estimates from several other companies with Cottam coming in below all of them, but not sacrificing quality or professionalism. A pleasure to do business with.

    Nancy Scotto
  • All aspects from the engineering and installation to the duct work, furnace, hot water heater to the smallest detail to taking the time to cover the flooring and cleaning after the work was completed and carried out in a friendly and professional manner

    Bruce and Donna Mayer
