Not all heating and air conditioning companies are created equal, especially in Illinois

Unfortunately, the State of Illinois does not mandate or regulate any technical skills or aptitude testing for HVAC technicians that enter your home. That is why Bella Heating & Air Conditioning takes great honor in our Factory Certified Technician Training Program. Our technicians are mandated to complete ongoing annual certification training and random drug testing. We have the utmost confidence in our skilled, polite, knowledgeable and courteous technicians and you will too, we guarantee it!
