What’s the difference?

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 Shamrock takes great pride in our Factory Certified Technician Training Program. All of our technicians must complete Factory Certification with a score of 90 or above. Then our technicians enter into a rigid 2 year training program with our National Technical Trainers, then they are background checked and drug tested. All this before they are allowed into your home. Our technicians are also 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!

We won’t let anyone into your home that we wouldn’t trust in our own homes.
