You have probably heard of the term HVAC. Have you ever wondered what it means? The term itself is used for heating and air conditioning systems installed in homes, buildings and businesses throughout the world. Its primary use and purpose is to regulate room temperature, humidity levels, air flow and to maintain safe and healthy indoor conditions. HVAC dates back as far as the second century, during Roman times, cities throughout the Roman Empire used a kind of central heating system (hypocaust).

Are you planning on replacing your old inefficient HVAC unit? Then you are making the right decision. Your old heating and cooling system is not powerful enough to provide sufficient amount of heat during the Chicago extended winter season and not enough cooling for the humid Chicago summer days. The harder that unit works the higher your energy bill will increase along with it. According to experts your HVAC system is responsible for more than half of your electric bills. The life expectancy of an HVAC system is between 16-20 years.
