Getting confused with all the jargon that comes along with learning about air conditioners? Don’t fret – here is a quick list of the most common (and commonly misunderstood) terms used in the HVAC industry. It’ll be helpful to understand these terms the next time you meet with your HVAC expert, so do read on!
Located in the outdoor unit of the air conditioner, the compressor in our air conditioner pumps refrigerant into the indoor portion of the air conditioners in order for the air conditioner to achieve the desired temperature.
Also part of the outdoor unit, the condenser releases heat from the air conditioner.
An abbreviation for Cubic Feet per Minute, it is a metric that determines the airflow volume required for a specific space. The determination of a house’s CFM is particularly important when narrowing down your options for the ideal air conditioner for your home.
An air conditioner that is shipped “dry” – that is, without refrigerant – to its place of installation, is called a dry-charged unit. Once it has been sent to its final point of delivery, only then is it filled with refrigerant.
The network of metal or synthetic tube – also known as ducts – installed into a home to transport air across different spaces. Ductwork is just as important with central air conditioning as it is when it comes to heating. Ensuring you have a clean and properly maintained ductwork is an important factor in maintaining the indoor air quality of your home.
Electronic Air Cleaners
Also known as electronic air purifiers or ionisers, electronic air cleaners use electric charges to gather and trap harmful airborne allergens, contaminants, and airborne particles in your home, improving overall indoor air quality.
Located inside the house, the evaporator coil absorbs the heat from the space you are trying to cool.
A collection of internationally-accepted ratings and standards used across the world to provide assurance on the quality of air conditioner units and products from different manufacturers.
An abbreviation of the Minimum Efficiency Reporting Value, the MERV Rating is able to measure the efficiency of air filters. A general rule is that the higher the MERV rating of the air filter, the smaller the holes it contains, which means it is able to trap more harmful airborne particles.
A chemical that provides a cooling effect, used on most air conditioners. It is also commonly known as Freon, but this is a term that’s only for a specific refrigerant, namely the R-22 refrigerant. Another type of refrigerant is the R-410A refrigerant which is more environment-friendly as it is chlorine-free.
An abbreviation of Seasonal Energy Efficiency Ratio, it is the primary rating you should check to understand the efficiency of air conditioning units. The higher an air conditioner’s SEER rating, the more efficient and cost-effective it is.
The device used to monitor the temperature of a home, which then adjusts the settings on your cooling system accordingly in order to maintain the desired room temperature.
