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 LP from Pickering on Twintech Heating and Cooling

All interactions from sales to installation were Courteous and professional. The installation was seamless and the attention to detail including clean up was outstanding. I highly recommend TwinTech Heating and Cooling.

by David in Pickering on Twintech Heating and Cooling

Twintech's Salesman Dave arrived promptly was friendly and courteous, listened and assured us the installation would be completed according to our requests. The crew arrived early morning on May 11th, 2018 and worked through till late afternoon non-stop. They were very friendly, very professional, their expertise was excellent, their workmanship outstanding and the installation was completed in a timely and efficient manner. We were completely satisfied and happy with the quality of the work.

by Jennifer in Toronto on Twintech Heating and Cooling

I had cold and hot spots all over my 70 yr old home. My furnace is quite new and Greg optimized the fan and furnace. The original installer just took it out of the box with factory settings and installed it- basically running at 50% of capacity. Greg also routed heat into my laundry room, yeah - so now I can renovate laundry room - thanks Greg. He is honest, professional and knowledgeable. I will be calling him back in the spring to optimize my AC as well.

by Happy Homeowner in Toronto on Twintech Heating and Cooling

Wonderful from beginning to end. I tend to fret and worry about home improvements but the excellent team at TwinTech put my mind as ease. They listen, they are patient and best of all ... the work they did is amazing! I chose the Goodman 80K BTU 2 stage furnace and the matching Goodman air conditioner. Greg, Grant and Poitr "Peter" arrived on time, took great care, explained everything to me and they answered all of my questions. They carefully adjusted the factory settings to optimize the furnace for my house and they also checked the duct work in the basement. Dave, the Sales Manager, came by to say "hello" and to see if I was happy. YES, I am happy with the work! The furnace is very quiet. I have it running on low just to circulate the air in the house and it's so much quieter than my old furnace. When I need new duct work for an upcoming basement renovation TwinTech will be my first choice. I highly recommend TwinTech. PS. They were even nice to my dogs.

by Les G. from Pickering on Twintech Heating and Cooling

Greg was prompt on the scheduled day of installation and the work was done well within the time estimated beforehand. Installation was neat and the equipment and scope of work was as specified in the quote. One item I must point out is that we were faced with a "No Heat" situation the day before the scheduled installation and Greg came out to address it free of charge. Not only that, but he also corrected an installation fault with our smart thermostat that was not part of the original job, again free of charge.

by one19 in North york on Twintech Heating and Cooling

Greg came by to do a routine furnace checkup. He was very knowledgeable and professional, letting me know what's being checked/adjusted and giving me tips to ensure everything runs smooth. Very honest and upfront about what's working fine vs. what may need to be fixed/replaced. He didn't attempt to up sell anything that wasn't necessary. I'm glad to have finally found someone I can trust and rely on for all my HVAC needs - furnace, A/C, and hot water tank.

by Paul M. from Toronto on Twintech Heating and Cooling

I'm very happy with the work that was done. Everyone from salesperson to the installers were friendly and professional. They were on time and cleaned up the job site after it was installed. They also answered all my follow up questions promptly. I wouldn't hesitate to work with them or recommend them again.

by Kathy D.in Ajax on Twintech Heating and Cooling

Thanks to the team at Twin Tech for a great job installing my new heat pump/ac unit. The guys were very polite and professional. When they left you would never have known they had been there except for the new Mitsubishi unit on the wall!! would highly recommend the Twin Tech team.

by varga p. in Pickering on Twintech Heating and Cooling

Installed professionally, no delays, no rework needed. Very reliable contractor and sales person. Also installed BBQ gas line and some duct work.

by Private User on Twintech Heating and Cooling

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

by Robert Mizuno on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
