Understanding the basics of air conditioner maintenance tips can go a long way toward ensuring optimal performance and longevity of your air conditioning unit. Regular cleaning, inspection, and tuning are essential to keeping running costs low while maintaining indoor comfort. Most people tend to neglect their air conditioning systems until something goes wrong. However, preventive measures such as regular filter replacement or coil cleaning can translate into significant savings in repair bills down the line. According to Energy Star estimates1, easy air conditioning maintenance tips and practices could save you about 15% on annual energy bills while extending its lifespan by up to five years.
In this post, we will outline nine easy-to-follow maintenance tips for keeping your air conditioner unit running smoothly around your home all year round. We will also focus on some home improvement concerns for your heating and air conditioning systems that you might be dealing with. Whether you own residential or commercial HVAC equipment in Chicago, IL (or similar climates), these maintenance steps around your air conditioners are guaranteed means of reducing system breakdowns during peak seasons without compromising cooling efficiency, so let’s jump right into it!
How Does an Air Conditioner Work?
Before we dive into essential air conditioner maintenance tips, let’s quickly take a look at how an air conditioner works around the unit. An HVAC system has numerous components; however, the basic principle behind its operation is turning hot and humid air into more refreshing, cool, dry air inside your home. The primary functioning parts of a room air conditioner unit include the compressor that pumps refrigerant gas between two sets of coils – the evaporator coil inside, where heat absorption happens, and the condenser unit coil outside, which releases absorbed heat back to the outdoor surroundings through fins.
Essential Maintenance Tips for Air Conditioners
Essential AC maintenance tips can help improve indoor air quality and energy efficiency while reducing the risk of unexpected repairs or costly system breakdowns. Here are some practical HVAC maintenance tips to keep your air conditioner running smoothly all year.
Clean or replace air filters
Cleaning or replacing air filters is one of the easiest and most effective maintenance tips for air conditioners. Dirty, clogged filters force your air conditioner’s unit to work harder than usual to maintain desired temperatures, increasing energy consumption and resulting in poor indoor comfort. Changing the filter every three months extend the life of your air conditioner. According to Energy Star2, not changing dirty filters can increase AC energy usage by up to 15%. A standard air conditioner filter change could save you more than $100 annually on electricity bills without compromising cooling efficiency during the peak season (days of summer).
Clear debris around the outdoor unit
Outdoor cooling system units face constant exposure to dirt, leaves, twigs, and other organic matter. As such, they require regular cleaning and conditioning services to function efficiently during the hot summer months. To keep the air conditioning unit running smoothly outdoors and minimize downtime on repairs:
- Clear debris around the AC condenser unit outside regularly using simple garden tools like a rake or broomstick. It allows the air to escape and makes sure your ac provides cool air.
- Trim nearby shrubs and lower tree branches that risk falling over the window AC unit in strong winds or severe storms.
By doing this periodically through each season of operation (or before startup if you live in colder regions), you can help reduce cooling costs by up to 30% while making sure these outside units last longer.
Check and clean the condenser coils
Condenser coils tend to clog with dust and dirt over time, reducing airflow and causing the compressor to work harder than usual. Inspecting the outdoor AC periodically (especially before peak seasons) can help you determine whether any debris is stuck in between or near the condenser unit. Simple tasks such as using a vacuum cleaner or hosepipe to gently wash away dirt from fin combs can prevent air restriction-associated issues like reduced cooling efficiency by up to 30%. According to Energy.gov statistics2, cleaning AC condenser coils could save up to 1-2% on home energy bills annually.
Inspect and clean the evaporator coils
Evaporator coils sit inside the hvac unit and absorb indoor heat to cool the air that passes over them to keep your home cool. Due to their position close to the moisture-laden indoor airstream, they tend to accumulate significant amounts of dust and grime on their surfaces with time. Regular inspection by an HVAC professional or DIY evaporator coil cleaning (with care) can increase cooling efficiency while preventing mold growth or sudden system failure episodes caused by reduced air circulation.
Clean and unclog condensate drains
A condensate drain line is responsible for draining excess moisture from the evaporator coil. Over time, this line can become clogged with dirt or algae. A blocked drain not only reduces efficiency but also creates an ideal breeding environment that can result in mold formation near the unit and indoor air quality issues (such as musty smells by blowing into your home). Simple ways to clean and unclog the condensate drains include pouring white vinegar through ports or changing out dirty traps from actual units regularly – depending on your unit layout.
Verify and adjust thermostat settings
The thermostat is the temperature control center of an HVAC system. Ensure that it’s accurate by manually cross-checking thermometer readings against what’s indicated on the device. You can calibrate this device if necessary or adjust its settings and power to the unit according to your comfort preferences, such as primary temperatures during the day and night (or high and low occupancy hours). According to Energy Star 3, a programmable thermostat saves about $180 annually without compromising internal climate standards.
Lubricate moving parts
Lubricating the moving parts of an AC system can significantly reduce friction and wear, which eventually leads to system breakdowns. The condenser fan motor, blower motor (in the case of central HVAC systems), or any other mechanical parts require proper oiling before peak season routine maintenance checks. According to the US Department of Energy, friction caused by a lack of lubricant accounts for over 40% of the energy used by belts and motors in a typical AHU (Air Handling Unit), meaning more wear translates into higher running costs.
Inspect and tighten electrical connections
Loose electrical connections are not only a source of system malfunction but also pose serious safety risks. Over time, exposed wires or corroded terminals in your air conditioner compressor increase the chances of an electrical fire, especially in high-power situations such as peak summer days. For safety reasons, it is wise to have wiring connections reviewed by licensed technicians occasionally. Likewise, cleaning if they show dust and blockage can reduce the chance of sparking to extremely low (1-2%), according to an EPRI Indoor Air Quality study3.
Check and clean blower components
Cleaning the blower components is essential to ensuring proper airflow and indoor air quality. Neglecting filters or fans can cause dirt and other contaminants to build up, increasing system strain that could lead to more significant repairs down the line. Experts recommend checking or replacing air filters at least once a month, especially during high pollen seasons when they quickly accumulate debris from outside environments. Keep in mind that HVAC filters come in different sizes and MERV ratings- usually ranging between 1-20, but higher-rated ones trap smaller particles much better without clogging faster.
Benefits of Regular Maintenance
Regular maintenance is critical to ensuring your air conditioner operates efficiently and lasts longer. It can help you save money by reducing the risk of expensive repairs or replacements due to wear and tear. Roughly every year, contact professional HVAC technicians who are trained to inspect, service, and repair various AC unit models, as some internal issues could be significant indicators hidden until it’s too late. Regular AC maintenance ensures:
- Increased energy efficiency, lowering electricity bills.
- Reduced repair costs by identifying and fixing small issues before they turn into major ones.
- Enhanced indoor air quality by removing pollutants that accumulate in HVAC systems over time.
- Extended AC lifespan to five or sometimes ten more years with proper care.
- Regular maintenance can prevent unexpected failure reducing the risk of high replacement costs.
By investing a little time in managing the simple tasks provided above, a specialized maintenance plan still pays off well because it ensures optimum air conditioning efficiency, ensuring comfortable seasons all year long.
How often do central air conditioners need maintenance?
