Conclusion. While air conditioning systems offer several health benefits, such as improved air quality, comfortable living environments, and better sleep quality, they can also lead to respiratory issues, skin dryness, and air-conditioning disease.

A furnace is part of an HVAC system that is used to generate heat for your home. A furnace is a heating unit, while HVAC is the system that includes heating and cooling units, ducts, and vents to distribute the conditioned air in a building.

The goal of your HVAC system is to make your ideal home comfort circumstances become a reality. To do this, a complete system must be built from a combination of an air conditioner, furnace, air handler, ductwork, thermostat and even some other units like a humidifier or air purifier.

If you have a common flu or cold, the air conditioning system can worsen symptoms like soreness of the throat, fever, nasal congestion, and cough. It is because an aircon throws dry air into the room that dries membranes and creates irritation of the throat.
