Quantrac Corporation has been providing HVAC software since 1992! The software was developed in a very successful, award-winning company, Airco Comfort Systems, Inc. and a team of software professionals.  There is no more intuitive and easy-to-use package available. 

Here we are, 23 years later and under the same ownership. Many of our current customers first computerized their offices in 1992 with our first release. We’ll be happy to share some of the names of our first users as well as those that are more recent. Our software is still very highly acclaimed by its users. We believe that HVAC Office is the easiest to implement and most user-friendly of all.

The HVAC industry is our only focus. HVAC Office is our only product. We are dedicated to serving this industry and don’t share our time with other products and other industries. HVAC Office has progressed through eleven releases since conception; all geared towards making the management of your company more efficient and profitable.



Please use our technical support help desk to contact us if you have any problems.  Doing so keeps a written record of every issue and helps me develop a user-friendly knowledge base.  It also helps me to track calls to make sure everyone's needs have been addressed.
