In 1987, Main heating and cooling was created in a basement in Warren, Michigan, we now operate from our office and warehouse in Shelby Township. Together with a love and knowledge of our community, our company has served the Metro Detroit area with dependable, quality repair and replacement services of heating and air conditioning products. We started out as a one-person operation and have grown to a 15-person team with the single-minded mission of meeting the needs of each customer on an individual basis. We have been a Lennox dealer since 1993 and have remained a dealer because of the commitment to quality and reliability Lennox has displayed for over 100 years. Being a Dave Lennox Premier Dealer ™ means that we are held to a higher standard than other heating and air conditioning companies by Lennox and ourselves. We have been honored to receive the Lennox Centurion Award several times in recognition of outstanding dealer performance, awarded to only the top 1% in our region. In the 21 years of business, technology has changed but our commitment never has, we are still providing quality services to homeowners and businesses alike. We look forward to hearing from you whether you need service or have questions regarding any heating, cooling or indoor air quality systems.
