Illinois HVAC Installation

JT Dunn Heating and Cooling technicians are trained to handle the heating and cooling needs of new or old homes in Illinois and Missouri. The HVAC codes are different on both sides of the river so the heating and cooling company you pick should be well versed in HVAC code. At JT Dunn, we go by the International Mechanical Code unless the local HVAC codes are different. Trust your HVAC installation will be installed to the highest standards when you pick JT Dunn Heating and Cooling – it is a little known fact that HVAC companies capable of installing on both sides of the river have more certifications and licenses than those that only install in Illinois.
