How Does an AC work?- Basics

Tom Markley • June 30, 2021

An air conditioner can change the temperature, humidity or general quality of the air. More specifically, an air conditioner makes your home cooler, by drawing heat energy out of the house and transferring that heat to the outdoors, then replacing the air inside your home with cooler air.


The air conditioner in a central heating and cooling system provides cool air through ductwork inside your home, by providing a process that draws out the warm air inside, removing its heat.


In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is then forced through the indoor evaporator coil or cooling compartment. The indoor unit’s fan circulates the inside air to pass across the evaporator fins. The evaporator’s metal fins exchange the thermal energy with the air around it. There, the refrigerant turns from liquid into vapor, removing any heat from the surrounding air. As the heat is removed from the air, the air is cooled and blown back into the house.


From that point, the condenser or outdoor unit then turns the refrigerant vapor back into a liquid, removing any heat. By the time the fluid leaves the evaporator again, it is a cool, low-pressure gas, eventually returning to the condenser to begin its trip all over again. This process continues again and again until your home reaches the cooling temperature you want, as programmed and sensed by your thermostat setting.

Choosing the right heating system can make a big difference in comfort and energy costs. For homeowners in Wayne, Holmes, and Ashland counties, Ohio, the most common options include natural gas furnaces, propane furnaces, and electric heating systems. But which option makes the most sense for your home? Natural Gas Heating: Efficient and Affordable Natural gas furnaces are a popular choice throughout Northeast Ohio. Modern high-efficiency furnaces can achieve 95% AFUE or higher, delivering reliable warmth during cold Ohio winters. For homes with access to natural gas, it's often one of the most cost-effective heating options. Propane Heating: Great for Rural Ohio Homes Many homeowners in rural Holmes, Wayne, and Ashland counties rely on propane because natural gas lines aren't available. Propane furnaces provide dependable heat during freezing temperatures. While propane can cost more than natural gas, high-efficiency equipment can help keep heating expenses under control. Electric Heating and Heat Pumps: A Modern Alternative Electric heat pumps have improved significantly in recent years. Unlike traditional electric furnaces, heat pumps transfer heat rather than generate it, making them much more energy-efficient. Modern cold-climate heat pumps can work even when temperatures drop below freezing. Some homeowners also choose dual-fuel heating systems, combining a heat pump with a gas furnace for efficient heating throughout the winter. Which Heating System Is Best for Your Ohio Home? The best heating system depends on fuel availability, energy prices, your home's insulation, and your budget. Whether you live in Wooster, Millersburg, Ashland, or the surrounding communities, choosing the right equipment can improve comfort and help control heating costs.
