Wood Frame of House

In 1987, Greg Allen opened A & A Air Services Inc. This business started out as a small one-man operation which has now grown into 30 employees out in the field.

A & A Air Services specializes in Residential and Light Commercial HVAC installation and Geothermal. Over the last 35 years A & A Air Services has grown into having a knack for the Geothermal field, and now holds the title of being one of the Top 5 Waterfurnace Geothermal Dealers in the United States.

In 2005 Greg expanded A & A Air Services into A & A Service Company.  A & A Service Company is managed by Greg’s daughter Mindy, with Greg standing side by side.

A & A Air Services is now in the 2nd generation of management/ ownership, with Greg’s son Chris taking over the day to day operations of the business.

Over the years A & A Companies has gained a valued reputation among the community for the quality of work that is performed down to the friendliness of the office staff. We pride ourselves in having a name that people know from the beaches of Delaware all the way to the Bay Bridge.
