How Heating and Cooling Systems Work Together

Central Cooling

Are you curious about how a heating and cooling system works? Well, the most common central cooling system is a split system, which includes an outdoor cabinet containing a condenser coil and compressor, and an indoor evaporator coil, usually installed next to your furnace or air handler. The compressor pumps a chemical called refrigerant (a compound typically found in either a fluid or gaseous state) through the system.

How Central Cooling Works

Once warm air inside your home blows across the indoor evaporator coil, the heat transfers to the refrigerant inside the coil. That transfer, in turn, “cools” the air. The refrigerant is pumped back to the compressor where the cycle begins again. The heat absorbed by the refrigerant is moved outside your home while cooled air is blown inside. Moisture that contributes to humidity is also removed from the air, which is great for humid climates!

Your cooling system is usually combined with your central heating system because they share the same ductwork for distributing conditioned air throughout your home.

Central Heating

Central heating systems have a primary heating appliance, such as a furnace, typically located in your basement or garage. All furnaces consist of four main components:

1. Burners that deliver and burn fuel

2. Heat exchangers

3. A blower

4. A flue that acts as an exhaust for gaseous by-products

You can choose from heating systems running on either gas or oil, or a hybrid system that can use both fuel types. Each system has its own benefits, so depending on your heating needs, see what works for you!

How Central Heating Works

Combustion gases are generated by the burners in your furnace and passed through a heat exchanger. Air from your home blows across the heat exchanger to be warmed. It is then blown through a system of ducts to distribute around your home.

During warm seasons, your heating system works with your central air conditioning. Air is cooled as it’s blown over your air conditioning unit’s cooling coil, often attached to the air circulating fan of the furnace, and then sent through the same air ducts throughout your home.


One can say that it’s pretty neat how a heating system and cooling system work together! There are so many components that go into building and maintaining a HVAC system, all of which are taken care of by your local service technician.

35.5 Reasons Why You Should Appreciate Air Conditioning

Here is a riddle for you. What do the following things have in common: water, toothbrushes, toilet paper, electricity, health, memory, roads, heating, and air conditioning? Don’t worry. I’ll give you a minute to consider this.

Yes, these are all vital aspects of modern society and you probably use each one on a daily basis. More importantly though, they are all easily taken for granted. It is only when one of these items is taken away from us that their value becomes apparent. Now you can add a lot of things to this list, such as a best friend or your favorite coffee shop. But let us give pause and appreciate heating and air conditioning for being there every time we looked at the temperature and thought, “There is no chance I’m leaving the house.”

The most recorded rainfall in Orangeville on a single day is 84 mm. The record was set Aug. 22 1968.

Orangeville, Ont. on Aug. 3, 1988

Brian Mulroney was the prime minister. “The Flame” by Cheap Trick was on top of the charts. “Cocktail” was on top of the box office and thermometers across Orangeville, Ontario read 35.5 °C. This day turned out to be the hottest day in recorded city history. While we don’t remember the exact details of what we did that fateful Wednesday, we are sure that we were not alone in staying as close as humanly possible to an air conditioning unit.

Orangeville, Ont. on Feb. 18, 1979

The most recorded snowfall in Orangeville on a single day is 30 cm. The record was set on Dec. 12, 1972.

Pierre Trudeau was the prime minister. The first women were enrolled in Canadian military colleges. Roberto Luongo was still three months from being born and once you scrapped the frost of an Orangeville thermometer, it read -36.5 °C. You probably already guessed it, this was the coldest day in recorded city history. Again, we don’t remember exactly what did this day, but considering it was a Sunday, odds are slim that any of us ventured passed the front door. We can say with certainty though that the heating system at home was definitely operating at full capacity.

For our friends that visit our Alliston location, the temperature records are pretty similar. The hottest known day in Alliston is 36 °C on Aug. 8, 2001 and the coldest known day was -35.5 °C on Jan. 16, 1994. Thankfully locals had air conditioning and heating available to negate these record temperature highs and lows. Do not take your HVAC systems for granted. As we enter into the coldest part of the year, make sure your systems are operating smoothly. That way you will never get caught off guard when extreme weather strikes.
