McDonald Air


We would like to take a moment to introduce you to our company. We are a state certified mechanical contractor (License #CAC1816995 | #CMC1250256) operating throughout Central Florida. We have a full service sheet metal shop, however, our specialty is in the fabrication and installation of any and all types of commercial or industrial air conditioning systems. We have been a proud member of the Sheet Metal and Air Conditioning National Association (SMACNA) since 1994.

Prior to 1994 the current owners, Ralph Carver and Matthew McGaffigan (retired), served in management of McDonald Air Conditioning. The owner and corporate officers of McDonald Air Conditioning began in Orlando in 1958 and all retired in June of 1994 after 36 years in Central Florida.

We presently have three full-time project managers who average over 25 years experience each. We also have five job foremen, five leadmen and average 40 to 60 SMWIA nationally certified or State registered sheet metal workers with an ability to increase these numbers as required with workers carrying these same credentials.

Our facilities house 4,000 sf of office space, clerical, project management and computerized estimation as well as 22,000 sf of manufacturing, including a full coil line, plasma cutting tables, mig and tig welding of black iron, galvanized, aluminum and stainless steel as well as a complete pipe fabrication shop.

We have had a satellite office in the Tampa area since 2003, employing 10 to 12 sheet metal workers.

Many of our clients order custom fabrication of ductwork, flashings, sleeves or saddles for direct pick-up or prompt delivery.

1. EARN THE OPPORTUNITY When bidding projects, we utilize the latest innovations and technical tools available to the industry.

It is with this in mind that our team comes together to ensure everything from correct, timely submittals to in-house coordination drawings of the very highest quality.
