Your Comfort Is Our Mission

RTI specializes in servicing commercial and industrial HVAC (Heating, Ventilation, Air Conditioning) systems for the last 12+ years.  With our experience, knowledge, and capabilities,  RTI will solve your most difficult HVAC problems.  RTI’s value comes from our professionally trained and certified Journeyman HVAC technicians working as efficiently as possible.  Please contact RTI for a complimentary energy consultation and preventive maintenance quote.


RTI appreciates and supports your efforts to save energy and reduce your electric bills.  We will partner with you to develop and implement strategies to keep your facility running as efficiently as possible and reduce your energy costs.  A well maintained, properly functioning HVAC system will provide better indoor air quality (more productive employees), temperature consistency (reduce thermostat tampering or "thermostat wars") and potentially extend the life of your existing HVAC equipment (extending the life of your equipment can have a substantial impact on your budget).  The energy savings go directly to your bottom line.

RTI's Energy Efficiency Program focuses on multiple strategies to maximize HVAC efficiency which will result in long-term energy savings and lower energy bills.  Click on the appropriate tab above for more information.
