Biggest Questions on Air Conditioning and What It Entails

Air conditioning is a process that allows you to regulate the temperature within a room or building to create a comfortable environment. This process works by removing warm air and replacing it with cooler air through an air conditioner or AC unit.

What Does An Air Conditioning System Do?

An air conditioning system is designed to maintain indoor temperatures cooler than the outdoor environment. Typically, this cooling occurs through a refrigeration cycle that includes a compressor, condenser, expan-sion valve, evaporator, and heat exchanger. The compressor increases pressure on the gas entering the unit, forcing it to condense into a liquid form. This pressurized gas then moves to the condenser, where it is cooled by a fan and several other elements that dissipate heat. The condenser is the only AC system component that interacts with exterior air, which can vary based on weather conditions. Once the heat is removed from the gas, it condenses into water and drains away via a drip pan and a drainage system.

When the warm indoor air meets the condensed gas in the evaporator coil (also known as an evaporative cooler), some of the heat energy is absorbed before the cooled air exits back through the home’s vents or return ducts.

The refrigeration cycle repeats as this condensed liquid is sent to an expansion device, where its pressure drops significantly, causing it to convert back into a gas. The AC heat exchanger has cool refrigerant flowing through it while hot air from the home passes over it. This causes the liquid inside to evaporate, absorbing heat from indoor air before heading back to the compressor to restart the cycle.

Thus, an air conditioner functions similarly to a reverse heater, conditioning or cooling indoor air rather than heating it.

How Do You Choose An Air Conditioner For Your Home?

The key factors in selecting an AC unit are its size (cooling capacity), efficiency (energy usage vs. cooling capability), and cost. The first step is to determine the required size based on your home’s square footage, which influences the type and number of units you'll need (e.g., window vs. through-the-wall units).

What are the different types of air conditioning systems?

Window AC: Window air conditioners are straightforward to install. Yet, if the unit exceeds 40 pounds, assistance may be required. Installation involves measuring and cutting mounting brackets and adding insulation around your wall for better insulation. The main advantage is no need for ductwork, making it a perfect choice for apartments or smaller spaces. While not as energy-efficient as central systems, they offer a cost-effective cooling solution.

Central AC: Central air conditioning systems, also known as split systems, are the most popular for home cooling. They require calculating the necessary BTUs (cooling capacity) and are connected via ductwork to supply multiple rooms evenly. Though more expensive and requiring professional installation, they offer superior cooling efficiency and are ideal for long-term stays in one location.

Top-loading AC: This type of central AC has an outdoor condenser linked to an indoor evaporator coil through copper tubing, and fits into smaller spaces without ductwork through walls or floors. They include vents and grilles in multiple rooms for balanced airflow, providing ease of maintenance and superior cooling capacity.

Bottom-loading AC: Similar to top-loading but with an indoor coil on one side and the outdoor unit on the other, facilitating easier access and better circulation in compact rooms. These systems often feature remote condensers, keeping the compressor outside while cooling indoor air via an evaporative unit.

Which type of AC is best for your home?

To choose wisely, assess each AC type's pros and cons based on your specific needs. Some homeowners prefer solar panels for additional savings through alternative energy, while others find ceiling fans effective in aiding airflow and reducing cooling costs. Identifying any strange noises, leaks, or performance inefficiencies in your current unit can also help determine if a professional assessment or a new installation is needed.

When Do I Need To Repair My Air Conditioner?

Regular AC servicing, such as belt replacements, can prevent motor damage. Visible damage to the evaporator radiator coils is another sign to call a professional.

Signs That You Need Your Air Conditioner Repaired

• Sibilant hissing noise when running
• Vibrations felt on walls
• Leaks in the refrigerant pipes
• Sudden shutdowns
• Smells like burning rubber
• Low pressure
• Failure to start up
• Cracks in the condenser coil
• Rusting of fan blades and evaporator fins
• Poorly positioned air outlets
• Proximity to heat sources
• Water dripping from vents
• Frequent temperature changes
• High operational costs
• Inefficient operation
• Short lifespan
• Sputtering sounds
• Slow cool down
• Uneven cooling
• Wetness accumulation around windows
