HVAC Services
We are located right in the heart of downtown Toronto



We provide complete HVAC services in Toronto for residential and commercial clients alike. Thousands of HVAC clients in the greater Toronto area can't be wrong. HVAC stands for Heating, Ventilation and Air Conditioning and is usually a term used to describe interior air systems. HVAC is sometimes referred to as climate control or heating and cooling but in essence, HVAC is basically a system built to regulate air temperature, regulate and control humidity levels and air quality in order to provide comfortable, enjoyable and healthy environment. There are 3 main parts to HVAC systems:
Heating
Heating is obviously very important in our part of the world as it provides us with the ability to have a very comfortable life even with extreme low temperatures outside. There are 2 main heating systems used in Canada:
- Oil based heating systems
- Gas based systems
As well there are 3 different distribution ways:
- Water heaters (radiators)
- Forced air
- Ductless systems (sometimes called Split Air Systems)
Cooling & Air Conditioning
Cooling & air conditioning is a different story here in Toronto and Canada as a whole. Because of our short, “easy” summer home owners are not as inclined to invest at “central” solutions and so we’ve got several different cooling systems:
- Central Air. Usually using the furnace existing duct system to spread the air throughout the house.
- Window air conditioners. The cheap and easy solutions but heavy on electricity, noisy and only good for one room.
- Ductless air conditioners or split systems. These are basically units built without ducts and designed to go through a wall, having vents and heat sinks both inside and outside.
Ventilation
Ventilation is a way to clean, clear and remove bad, stale air or smoke throughout the house.
