Maintain Indoor Air Quality with Air Conditioning Installation During Wildfire Season
June 13, 2025At RT Heating & Air Conditioning, we believe that the more you know about your HVAC system, the better prepared you are to make smart, energy-efficient choices for your home. One of the most common questions we receive is: How does an air conditioner actually work? If you’re considering a new air conditioner installation in Red Deer or simply want to understand the system you already have, this guide is for you.
The Basic Principle: Heat Transfer
Air conditioners don’t create cold air in the way a furnace creates heat. Instead, they remove heat from the indoor air and transfer it outside. This is done through a refrigeration cycle involving a chemical refrigerant, a series of coils, a compressor and fans.
The Key Components of an A/C System
- Evaporator Coil
Located inside your home, usually connected to the furnace or air handler, the evaporator coil is filled with cold, low-pressure refrigerant. As warm indoor air passes over the coil, the refrigerant absorbs heat, cooling the air.
- Compressor
The compressor, located in the outdoor unit, compresses the refrigerant, increasing its temperature and pressure. This prepares the refrigerant to release the absorbed heat.
- Condenser Coil
In the outdoor unit, the hot, high-pressure refrigerant flows into the condenser coil. A fan blows outdoor air over the coil, which helps release the heat from the refrigerant into the environment.
- Expansion Valve
Before re-entering the evaporator coil, the refrigerant passes through an expansion valve, which reduces its pressure and temperature, allowing it to absorb heat once again.
The Cooling Cycle in Action
Warm indoor air is drawn into your HVAC system through return ducts.
- This air passes over the cold evaporator coil, where heat is absorbed by the refrigerant.
- The now-cooled air is pushed back into your home via supply ducts.
- The warmed refrigerant travels to the compressor and then to the condenser coil, where the heat is released outdoors.
- The refrigerant returns to the evaporator coil to repeat the cycle.
Smart Air Conditioning Add-Ons for Better Performance
Modern systems can be equipped with smart thermostats and air filtration systems to improve comfort and efficiency. Advanced filtration also improves indoor air quality during the cooling process.
Why Professional AC Installation Matters
Whether you’re upgrading an aging unit or planning new air conditioner installation in Red Deer, professional sizing and installation ensure your system runs efficiently and safely. Undersized or poorly installed systems struggle to cool your home, waste energy and wear out faster.
