Understanding HVAC Systems Better

Whether you are cooling your office in the summer or keeping your home comfortable in the winter, HVAC systems have become a part of your everyday life.


Your heating, ventilation, and air conditioning (HVAC) system is the combination of different systems used to provide a comfortable temperature in your home, and it also maintains high levels of air quality.


As homeowners, it is important for us to understand the key roles that our HVAC system plays as well as how they operate in order to get the most out of them.


HEATING The heating component of an HVAC system provides a warm and cozy climate for your home in the colder months of the year.


With today’s technology, the most popular type of heating system would be the forced air system, but there are homes that use radiant and geothermal heating systems, among others.


Regardless of what system you use at home, heat is still created at a central source and it is distributed through the home via different ways.


 No matter the type of system you have, your HVAC system will make your home warm and enjoyable for you and the whole family during cooler months.


 VENTILATION Ventilation plays a major role as it helps circulate and purify your indoor air.


It also helps control moisture levels, prevent air stagnation, and remove unwanted odours.


Ventilation can be done naturally (with fans and windows) or mechanically, and even through a combination of those two – but this depends on the age of your home and the HVAC system that you have.


 Forced air systems pass the air in your home via an air filter that keeps volatile organic compounds (VOCs), airborne particulates, and allergens out of your home.


In such cases that you do not have a fixed air system, this can still be done using aids like air purifiers, air cleaners, humidifiers, and humidifiers.


 Understanding how your HVAC system helps keep your home ventilated is the first step to addressing any allergy or breathing issues that you and your family might be encountering throughout the year.


 AIR CONDITIONING In addition to heating and ventilation, your HVAC system is also responsible for keeping your cool during the warmer months.


There are different types of AC units that come with their own pros and cons.


It does not matter if you are using central air, split or ductless units, portable AC units, or window AC units, the process that each system uses to cool homes is similar.


 Your cooling system, as it collects and expels heat from inside your home, circulates refrigerant that changes from gas to liquid.


It passes warm vapour refrigerant through its compressor where it is transformed into hot refrigerant vapour and then moves to the condenser.


The hot vapour, when in the condenser, becomes cool as air from the condenser fan passes over its finned coils and will then turn into hot liquid.


This hot liquid will pass through the expansion valve, creates a low pressure, cool liquid mist that will run through the evaporator coil.


As the cool liquid mist evaporates, it then absorbs the heat from your house’s indoor air and returns to the compressor – this restarts the whole process.


The absorbed heat is then pushed outside by the system, leaving your home cooler.


 Now that you understand the roles that your HVAC system plays in our lives, you can maintain your system better, learn more about it, determine what might be missing, and purchase a new system as needed.

by MB, Ajax on Twintech Heating and Cooling

Installation was done quickly and professionally. The new furnace is quiet and provides even heat.

by Richard from Oshawa on Twintech Heating and Cooling

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

by Darcy from Pickering on Twintech Heating and Cooling

This company was great to deal with. Our furnace went down and they installed a new furnace the next day with a lot of professionalism!

by gillian hooton from Uxbridge on Twintech Heating and Cooling

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.

by alisiena from Toronto on Twintech Heating and Cooling

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

by David from Toronto on Twintech Heating and Cooling

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

by Jaime-Lynne in Pickering on Twintech Heating and Cooling

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

by Matt C. Oshawa on Twintech Heating and Cooling

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

by B Davis in Pickering on Twintech Heating and Cooling

I don’t usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and I’m sure you will be too.
