Gas or Propane:

Gas Furnaces have come a long way. Royal Air Systems, Inc. now offer gas furnaces in single stage, two-stage and modulating configurations. Within these configurations Royal Air Systems, Inc. can achieve AFUE ratings up to 97% and an increased home comfort that evens out the wide fluctuations of the past.

Today's furnaces include:

  • Communicating Interfaces that allow thermostats ranging from non-programmable basic, a more advanced programmable thermostat to a WIFI enabled control giving you constant connectivity to your home from your wireless device (cellphone).
  • Direct Vent piping eliminating the need of a chimney


Oil Furnaces currently boast a burner efficiency of up to 85% AFUE. The major changes in the new oil furnaces include variable speed blower assemblies that save in electrical operation and work better with leading edge air conditioning and heat pump systems. They are able to be utilizied in a hybrid system for maximum energy savings. The new systems are compatible with today's control technologies allowing for programmable thermostats as well as communicating WIFI controls.

Whether you are replacing an existing system, or designing a new system including distribution, our team has the knowledge and experience to create the perfect home comfort system for your family.
