What is an HVAC system and what does it do

The term HVAC system comes up quite often, especially when looking at the specifications of a home. Whether it's brand new or older, what is an HVAC system, and what does it do? 


HVAC stands for heating, ventilation and air conditioning. The HVAC system is responsible for keeping your home cool in the summer and warm in the winter, and it also controls the indoor air quality. For an HVAC system to work effectively, you must replace your furnace filter every 90 days or less, depending on how often your furnace or air conditioner is on.


 Not only will the HVAC system rely on the furnace and air conditioner, but ductwork as well. Any cracks in the ductwork will cause the warm or cool air to leak out and not go where intended. Air quality can also be significantly affected when ductwork is not properly maintained. 


The HVAC system works by sending the warm or cool air through the ductwork and to the various rooms in your home. The thermostat is responsible for controlling the HVAC system. 


When the air in the house has fallen or risen below the set temperature, the thermostat will tell the heating or cooling unit to come on. And will stay on until the home is comfortable again. 


Thermostats come in different brands, with some you can even control when you are not at home. These are called thermostats and are becoming more popular with homeowners. Smart thermostats can even learn about the house and adjust the temperature accordingly, saving you money on energy bills. If you heat your home with natural gas, you could even qualify for a discount on a smart thermostat. 


But HVAC systems are not just in homes. You will find them in other buildings such as hospitals, restaurants, etc. Hospitals rely on their HVAC systems for sanitization, whereas restaurants need them for refrigeration. 


Keeping our HVAC system running is the best way to ensure your home stays comfortable. This means routine maintenance on your furnace, air conditioner and ductwork. If it's been a while since your HVAC system's last maintenance, Twintech Heating and Cooling is here to help.


One of our technicians can come to your home and inspect everything from your furnace, air conditioner and ductwork. And we will let you know if any repairs are required.

We are very pleased with the work done by Twintech. They were very professional from start to finish. Dave came to our home and gave us a very competitive quote for new high efficiency furnace and air conditioner. The installers were very courteous and professional. We would highly recommend them.

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)

The service was Twintech was excellent.
Dave our salesperson was easy to talk to and was professional. The unit recommended meets our needs and budget.
Greg and his team arrived on time for the installation and even got rid of the garbage the contractors left in our furnace.
Would definitely recommend Twintech.

by Steve V, Toronto on Twintech Heating and Cooling

Our old water tank was installed in 1997. Wasn't working as well as it should so we looked into a tankless as it is more efficient and a space saver! we had used Twintech in the past for a furnace cleaning and were satisfied with that so we decided to ask for a quote for the changeover. Gary arrived and provided the options and the quote fit within our budget so we decide to go with them after receiving a few alternative quotes from other companies. They did what the said would be done and it was completed within a reasonable time frame! Removal and cleanup of the old tank was seamless. We are now enjoying consistent and efficient Hot water! I recommend Twintech and would use them for future projects!

by New AC Unit + Humidifier on Twintech Heating and Cooling

One of the most honest HVAC companies out there! Dave was very helpful and informative in helping us choose a new AC unit. While they weren’t the lowest quote, we went with them because we trusted Dave and he was the most honest guy out of the companies that quoted us.
Greg and his crew who installed the unit were very professional and did a great job. If I could do it over again I would choose Twintech again.

by Private User on Twintech Heating and Cooling

Relocated and replaced our air conditioning unit. Fast, professional, and high quality service. We would definitely use them again for future projects!
