Unit Heating and Cooling System

Every day, we adjust a thermostat on the wall and expect our homes to respond, delivering warm air on a frigid winter night or a cool breeze during a summer heatwave. But what is the complex system responsible for this modern miracle of comfort? It’s your unit heating and cooling system, often referred to as the HVAC (Heating, Ventilation, and Air Conditioning) system. This system is arguably the most important and hardest-working appliance in your home, and understanding how it works is the first step to ensuring it runs efficiently and reliably for years to come.

At Excellent Air Heating & Cooling, we are the Rochester area’s premier experts in all aspects of home comfort. From emergency repairs to high-efficiency installations, our certified technicians have a deep understanding of every component that makes up your complete unit heating and cooling system.

What Exactly Is a “Unit Heating and Cooling” System?

The term refers to the combination of equipment designed to handle both the heating and cooling needs of your home. For most homeowners in our region, this isn’t a single, monolithic box but rather a “split system” composed of two main parts that work together: an indoor unit and an outdoor unit.

1. The Indoor Unit: Located in your basement, attic, or a utility closet, this is typically your furnace or an air handler. Its primary job in the winter is to create heat. In the summer, it works with the outdoor unit to circulate cool air. The powerful blower motor inside this unit is responsible for moving conditioned air through your home’s ductwork.

2. The Outdoor Unit: This is the large metal box located on the side of your house. It’s either an air conditioner (which only cools) or a heat pump (which can both heat and cool). Its job is to release heat from your home into the outside air during the summer.

Together, these indoor and outdoor components form a complete unit heating and cooling solution, seamlessly controlled by your thermostat to provide year-round comfort.

Exploring the Different Types of Systems

While most systems are split, the specific equipment can vary. Excellent Air has the expertise to service and install all configurations.

The Traditional Furnace and AC Combo

At Excellent Air Heating and Cooling, our commitment to quality HVAC service means using state-of-This is the most common setup in New York.

• The Furnace: A powerful gas furnace provides robust, reliable heat during our cold winters by burning natural gas to warm a heat exchanger. The air from your home is blown across this hot surface and then distributed.

• The Air Conditioner: The outdoor AC unit works in tandem with an indoor evaporator coil (which sits on top of the furnace). It uses refrigerant to absorb heat from your indoor air and transfer it outside, effectively cooling your home.

The Highly Efficient Heat Pump System

A heat pump is a remarkable piece of technology that functions as an air conditioner in the summer and a heater in the winter.

• How it Works: Instead of creating heat, it moves it. In winter, it extracts ambient heat from the outdoor air and moves it inside. In summer, it reverses this process. This makes it an incredibly energy-efficient unit heating and cooling option, especially during the milder days of spring and fall.

• Dual Fuel Systems: For maximum efficiency in our cold climate, a heat pump is often paired with a gas furnace in a “dual fuel” system. The heat pump handles the heating on cool days, and the powerful furnace automatically takes over when the temperature drops significantly, ensuring you always have the most cost-effective heating source running.
