    Needed thermostat, ours was burned out somehow
    Could only use the thermostat that controls all parts: furnace, air conditioner humidifier
    And matches the equipment
    Had Kalins for 42 years, Did sold us our first furnace
    But we're shocked at the cost of thermostat
    Response from the owner:Dear Jerry,
    Thank you for being a Kalins customer for 42 years - that is amazing! We know that thermostat is a big investment and we truly appreciate your understanding. Thank you for being a valued and loyal member of our Comfort Club!

    Super job! These guys are very professional& true gentlemen! My furnace also needed attention & they had to replace an expensive part, but I think it was worth it for the home that I love.
