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.

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

by Connie in Pickering on Twintech Heating and Cooling

The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

by Valentine in Pickering on Twintech Heating and Cooling

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.

by Jiri in Toronto on Twintech Heating and Cooling

From the initial contact we had an excellent experience with this company and all its personnel. Dave Gergley was an excellent, helpful, sales person and solicitous of our needs. He recommended only what was required and did not up sell or make any suggestions for products that we did not need, such as a new A.C. He explained the rebate process and basically outlined how to get the best furnace at the lowest price. When it was time for installation, the technicians could not have been more considerate, careful, attentive to detail, obviously committed to safety and optimum functioning of the appliance they were setting up. We have been perfectly satisfied with the functioning of the furnace and all aspects of acquiring it from the initial contact with Dave through to the installation process and follow ups inquiring about our satisfaction. Also they initiated the rebate process and contacted the appropriate inspection agency to carry it out. We highly recommend this company for all heating and cooling needs and we will contact them again when it is time to replace our A.C.

by Drew in Pickering on Twintech Heating and Cooling

Twintech was excellent from the initial quote and throughout the install. They had a competitive rate for hot water tank and ended up buying the tank from them, had them remove the old tank and install the new one. The day of install they were prompt and out in about 2 hours. Professional , courteous really great guys. We took a look at my 30 year old furnace and they were able to offer some suggestions for future there too.

by Harry in Toronto on Twintech Heating and Cooling

Ever since I turned on my furnace on Oct 2018 I hear a humming sound when the furnace fan kicks in. I called Adamson Air System who installed my furnace 7 years ago and couldn't figure it out the problem. I just wasted money to the guy who couldn't figure it out. I found Twin Tech via Amana / Goodman website. I checked the reviews from previous Twin Tech customers. I called Greg and was onsite on time this morning Sunday, Nov 25 2018. He figured it out what's wrong with the furnace and explained what the previous installer (adamson air system) did wrong when they installed it. His knowledgeable about his job. He recommend to replace the fun motor because the sound is not normal when it's running. Looking forward to see him again to replace the fan motor.

by Roger in Pickering on Twintech Heating and Cooling

Our house is over 22 years old and I had been researching furnaces and A/C brands for a while and thought it was time to take the plunge. After calling three different companies to come in and quote the job, this one won me over. From the first visit from Dave all the way to the end of the install by Greg, Grant, and Piotr, I was glad to have picked this company. Dave was very knowledgeable and really took the time to explain what kind of quality installation I was going to get as well as showing me some of their previous work and certificates.

I was also surprised at how quick the installation took and how nice everything looked afterward, I mean it's only a furnace right? They even re positioned the furnace so that I have easier access to my filter and humidistat, awesome! If you are looking for a company that cares about their customers and is proud about the quality of work they do, along with a great and competitive price, then stop right here because you found it.

by Louis in Pickering on Twintech Heating and Cooling

Once our AC Unit started to fail, I called our past Heating & Cooling provider for support. The response was we needed a new motor for our Furnace. It was time to check their Quote against the marketplace, I reached to other providers online. One of the owner of Twintech (Greg), called me and offered a preliminary Quote and recommendation online. The others needed to set an appointment and came to measure and spend 1 hour before offering a quote. Then I asked Twintech to come finalize their quote to make sure their recommendation was aligned and met our needs.

Twintech was professional throughout the process, easy to deal with (Web, Phone and in Person), price right and met their commitment. Their team expedited the process and installation, arranged for a energy assessment for available rebates and most importantly, delivered on their commitment and managed to do a few extras. They installed a New Furnace, AC unit and Nest thermostat in a day, remove all older units, left the house and outdoors clean and without any debris. Great to be able to support a Local Company, Neighbour and Professional team - Well Done Team Twintech !!!
