The ABCs of Air Conditioning

Air Conditioning 101

In the summer, having working air conditioning is essential. However, it’s crucial that air conditioners are in good condition and working efficiently. But to keep them in good shape, homeowners should have some basic knowledge about air conditioners. This is a brief guide to help homeowners learn about the most common types of air conditioning systems, maintenance, and signs AC repair is needed. 

Which Type of Air Conditioner Works Best for a Home?

The best AC system for a household depends on many factors, such as the budget, home size and layout, and lifestyle. A central air conditioning system is one of the most common and recognizable options available and works well for multi-story houses. Central AC cools the entire home evenly, controlled by a thermostat. It replaces hot indoor air with air that has been passed over an evaporator coil. Refrigerant is then able to absorb both heat and humidity. Once the blower fan sends cool air through a system of air ducts and vents, it will disperse throughout each room.  

Another common AC system installed in homes is a ductless mini-split system. Unlike central AC, mini splits do not need ductwork to deliver cool air to the house and instead use multiple indoor units in different zones of a home that can be individually controlled. Homeowners can save money by adjusting the temperature in the rooms they are not actively using. Additionally, not having air ducts eliminates the energy loss that occurs in the ducts of a central AC system. While central AC systems are initially less expensive, ductless mini split air conditioning systems are more energy efficient and cost less to run monthly. 

How to Tell if an Air Conditioning System Needs Repairs

Occasionally, air conditioners can experience issues that affect their performance and require professional repair. Homeowners can tell their AC system needs repair by watching out for certain signs that indicate a problem, such as: 

• The system is blowing warm air
• Low airflow from vents
• Faulty thermostat reading
• Strange odors or sounds
• Spike in energy bills 
• Liquid leaking from the system

Once someone notices one of these signs, they should contact an HVAC contractor to inspect their air conditioning system to determine the issue and repair it before the problem gets worse and causes more damage to the system. 

Air Conditioner Maintenance 

Annual air conditioning maintenance is recommended to keep an air conditioner functioning correctly and prevent issues. In addition to avoiding repairs, routine maintenance also helps extend the lifespan of an air conditioner and improves its efficiency, which helps keep energy bills low. It’s also much less expensive to maintain an AC unit than to deal with constant repairs.

During an AC maintenance visit, an HVAC technician can inspect the system to identify and fix potential issues before they get out of hand and perform essential tasks to help the AC. These tasks include cleaning the air conditioning coils, checking the thermostat settings, and checking the refrigerant level. In addition to hiring a professional for annual maintenance, homeowners are encouraged to change their air filters when needed, usually at least once every three months, to help maintain their system.
