Furnace and Air Conditioner - How Do They ACTUALLY Work?

If you do not have any prior knowledge of them, heating and cooling systems are quite complex equipment to deal with. So, if you have not been trained to work on them, it is likely that you will have many questions concerning your air conditioner, furnace, heat pump, and other HVAC equipment. Don’t worry – we are here to help you! 

Furnace: How Does It Work? 
Most people have the idea that furnaces heat homes or businesses, but they have some questions as to how exactly it is done. Furnaces heat a home or a business by warming air and circulating it into the indoor living or work areas. Furnaces can be electric or powered by a heating fuel such as natural gas, oil, or propane. 

In a gas furnace, the system’s ignitor or pilot light fires up the burners in the combustion chamber. These burners produce heat and move into the heat exchanger. The heat then is transferred to the air cycling through the furnace. The heated air is then moved by the system’s blower through the duct system and into a home or business. 

In an electric furnace, on the other hand, the electricity starts the heating process rather than the ignitor or pilot light. Heating elements warm the air instead of a gas burner. Air passes through the electric resistance coils of the heating element, and heat is transferred to the air supply. The blower circulates the heat to interior areas. 

Air Conditioner: How Does It Work? 
There are many users who have HVAC questions about how an air conditioner actually works. This cooling equipment is made up of four elements: the compressor, evaporator, condenser, and expansion device. Indoor air circulates through the system by passing over the evaporator coil which is located inside homes. Inside the evaporator coil is the refrigerant which absorbs heat from the air, and then transforms from liquid to vapor. 

Vaporized refrigerant then moves to the compressor, and this is located outside. The compressor compresses the vapor, thus increasing temperature and pressure. Next, the refrigerant moves to the condenser. The condenser now condenses the refrigerant gas back into its liquid form, allowing heat to radiate out. The metal fins that surround outdoor components allow the heat to be dispersed into the outdoor air quickly. 

The refrigerant moves back to the interior system in a cooled state, still in liquid form. The expansion device now regulates the refrigerant flow going into the evaporator coil. 

Once the heat is extracted from the air in the evaporator coil, the blower then will move the cooled air back into the interior spaces. This process is repeated until the desired temperature has reached the indoors.

by Tracy, Pickering on Twintech Heating and Cooling

We couldn’t have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.


We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.


Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.


Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

by Skapoor, Ajax on Twintech Heating and Cooling

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

by Steve, Oshawa on Twintech Heating and Cooling

We were very pleased with every aspect of the work that was done. They were very professional and polite. They arrived when they said they would and job was completed on estimated time


We would highly recommend them to whoever needed a recommendation


We have a very large dog and they were very understanding and respectful of him being around

by Patrick, Toronto on Twintech Heating and Cooling

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.


The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.


Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

by Ed, Whitby on Twintech Heating and Cooling

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

by Fred, Toronto on Twintech Heating and Cooling

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

by Elle, Oshawa on Twintech Heating and Cooling

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.

by John & Linda, Ajax on Twintech Heating and Cooling

We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.

by Bill, Whitby on Twintech Heating and Cooling

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.

by Nadia, Toronto on Twintech Heating and Cooling

The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.
