HVAC Terminology You Should Know

HVAC Terminology You Should Know

The HVAC industry is filled with technical terms that can confuse homeowners. Whether you’re dealing with a minor issue or scheduling routine maintenance, understanding HVAC terminology can help you communicate more effectively with your technician and make informed decisions about your AC system.

This blog will discuss some essential HVAC terms that every homeowner should know. Efficiency Heating & Cooling, your trusted HVAC repair and AC service in Saskatoon, is here to help you navigate the HVAC world and ensure your home stays comfortable all year round.

Components of an HVAC System

Air conditioner (AC)

The AC unit is responsible for removing heat and humidity from the air in your home to create a cool and comfortable environment. It works by evaporating refrigerant in the evaporator coil and then condensing it in the condenser coil to release heat. We have been providing AC service in Saskatoon, and our professionals can help you if you have any queries.


The furnace is responsible for heating your home during the colder months. It works by burning fuel (natural gas, oil, or propane) to create heat, which is then distributed throughout your home by the duct system.

Duct system

The duct system is a network of pipes and ducts that carries air from your HVAC system to the various rooms in your home. The duct system should be appropriately sized and sealed to ensure maximum efficiency and comfort.


The thermostat is the control center of your HVAC system. It allows you to set and control your home’s temperature and program and schedule your HVAC system. If you reside in the area and require professional service, please schedule an appointment with us for HVAC repair in Saskatoon to get started.

Important HVAC Terms

SEER (Seasonal Energy Efficiency Ratio) 

SEER measures an air conditioner’s efficiency. It represents the amount of cooling output delivered per unit of energy consumed. A higher SEER rating means that the unit is more energy-efficient and will cost less.

AFUE (Annual Fuel Utilization Efficiency)

AFUE measures a furnace’s efficiency. It represents the percentage of fuel that is converted into usable heat. A higher AFUE rating means that the furnace is more energy-efficient.

BTU (British Thermal Unit)

BTU is a unit of energy used to describe an HVAC system’s heating or cooling capacity. It represents the energy required to lift or lower the water temperature by one degree Fahrenheit.


Refrigerant is a substance used in air conditioners to transfer heat from one place to another. It circulates through the AC unit, absorbing heat from the indoor air and letting it go outside.

Load calculation

Load calculation is essential in the HVAC design process. It involves determining your home’s heating and cooling needs based on factors such as square footage, insulation, windows, and local climate. The load calculation helps to ensure that your HVAC system is sized correctly to meet your needs.

HVAC Maintenance and Repair


Regular maintenance is essential to keeping your HVAC system running smoothly and efficiently. This includes cleaning or replacing filters, checking refrigerant levels, and checking for leaks or damage.


When your HVAC system is not functioning correctly, it may be necessary to repair it. This can involve fixing leaks, replacing faulty components, or adjusting settings to improve efficiency. Call us today for HVAC repair in Saskatoon.
