As a homeowner, you may be easily confused by the term “HVAC.” Sure, you’ve heard it before and probably have a general understanding as to what HVAC is, but do you really know all of the types of services that fall under the HVAC umbrella?
Today, we will go into further detail regarding what exactly HVAC is, along with the several types of services that fall under it.
What is HVAC?
HVAC is defined as Heating, Ventilation, and Air Cooling. The term refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling your property. HVAC is what keeps you warm & cozy during the winter, and cold & fresh during the summer. Additionally, HVAC systems are used to control the quality of air in your home, filtering out dust, allergens, and other particles that may be present.
How does HVAC work?
Put simply, HVAC equipment is meant to move air, whether it’s heating or cooling an indoor space. Typically, HVAC systems contain three major elements: a heating unit, cooling unit, and duct to move the air.
In some cases, your equipment may be separate. This is commonly seen in radiant systems combined with window air conditioning units. More commonly, we see combined systems, such as central heating and AC systems that use a single blower to circulate air via internal ducts in a home, or with a ductless system for different rooms or zones in the house.
Most people don’t want to know how their HVAC unit works until it stops working. With HVAC repairs and replacements being relatively costly, it is important to learn how your HVAC unit works so that you can properly maintain it and avoid repairs down the line.
Heating Your Home: How It Works
The majority of homes in North America rely on a central furnace to provide heat in their home. The furnace is responsible for blowing heated air through the ducts that deliver warm air throughout the house. Below, you can find more information regarding how the process of heating your home works.
Furnace – Generates heat through electrical energy or burning its fuel source (typically gas, but can be propane or oil as well).
Heat Pump – When heating, the heat pump absorbs heat from the outdoor unit and transfers it inside. A common myth is that heat pumps
Cooling Your Home: How It Works
A common myth is that air conditioners create cold air for your home. This is not the case, as air conditioners and heat pumps actually absorb heat from within a home, then move it to the outdoor unit. Below, you can find a more information regarding some of the most important aspects of an air conditioning unit.
Refrigerant – Your cooling unit uses a chemical compound called refrigerant to absorb environmental heat and provide cool air once run through compressors and evaporators. It is important to make sure that you use the right kind of refrigerant, as the incorrect one can damage your unit.
Heat Pump – Opposite to its’ function in heating, a heat pump can do the reverse during the cooling stage. During cooling, the heat pump is responsible for absorbing heat from the inside and transferring it outside.
Ventilating Your Home: How It Works
Ventilation is defined as the process of replacing or exchanging air within a space. This results in better quality of air in addition to the removal of moisture, dust, allergens, etc. Listed below are some of the key points for ventilation in your home.
Ductwork – The system of ducts (metal or synthetic tubes) responsible for transporting air from the HVAC equipment throughout your home.
Chimney Flue / Vent Stack – Used to get rid of excess heat.
If you happen to notice any problems with the heating and cooling, or quality of air in your home, then it is probably time to get your HVAC equipment serviced. We recommend staying away from DIY projects, as any mistakes could cost you significantly more money in the long run.
Below, we have listed the 5 most common signs that indicate your HVAC unit may require a maintenance or repair.
- Change In Airflow
- Increased Energy Bill
- Old Age
- Noises and Smells
- Excess Moisture or Dust
Since homeowners rely on their HVAC system to keep them comfortable year round, regular maintenance is recommended to ensure that your system produces and distributes air how you’d like it to.
