Air Conditioners are crucial to daily tasks when it comes to hot and humid areas. It is important to note, however, that an AC system that is not functioning properly will lead to energy bill overload. Saving money and extending the life of your unit is possible when you avoid these drawbacks by optimizing your system. Upgrades and maintenance to your systems can make a world of difference to an AC’s performance and operability. Below are eight tips that can greatly enhance your performance and ensure peak efficacy.
 

1. Regularly Clean or Replace Air Filters

Improper airflow due to dirty air filters can cause your AC System to overexert itself. Air filters may greatly boost performance and allow the system to adequately function without dust accumulation, blocked indoor air channels, or obstruction. They are also great for maintaining good air quality and shielding you from worsening allergies, breathing problems, and other respiratory healthcare issues presented by clogged filters. It is advisable that one checks their filters on a month to month basis in addition to cleaning or replacing them if need be. If you live in a dusty area or have pets, do not worry! You can replace your filters as often as you deem necessary.

2. Keep the Condenser Unit Clean and Unobstructed

The outdoor condenser unit greatly helps in relieving heat from the house. When dust, trash, or leaves pile up around the condenser, it affects air circulation and efficiency. The condenser coils assist in losing heat; if they are covered with dirt, the unit has to work double to cool your house. Make sure it is clean and that there is no less than two feet of space on every side. Be removing obstructions regularly, and do not hesitate to use the garden hose to wash the dirt that has built up on the coils. Good maintenance of the air-conditioning system’s condenser unit increases the performance and longevity of the system.

3. Schedule Annual Maintenance

Maintenance checks from skilled professionals can save you money by catching problems before they become expensive repairs. A trained technician evaluates the refrigerant levels, cleans the coils, and checks all electrical parts. Failure to service your air conditioner regularly can hamper proper functioning, increase chances of breakdown, and drastically reduce the unit’s lifespan. Refrigerant leaks stuck thermostats, and blocked drainage pipes are some problems that can be resolved by technicians during maintenance checks, increasing the efficiency of the air conditioner. You can save money spent on repairs and increase energy efficiency throughout the year with an annual AC tune-up.

4. Use a Programmable Thermostat

Programmable thermostats can set specific temperatures for various periods of the day, which can help save energy by raising the temperature when you are away or asleep. The term smart thermostat refers to those that can adapt to your habits and automatically make changes for optimal efficiency. For example, setting the thermostat to 78°F (26°C) when the individual is home and increasing it when they are not can lead to substantial energy savings. There are even some that can be adjusted with smartphones, making it easier to change the settings depending on the weather or schedule changes.

5. Seal and Insulate Ductwork

Duct leaks can result in massive energy inefficiencies because the air conditioner will have to work harder to cool down the house. Check for any leaking ducts and seal them using duct tape or mastic sealant. In addition, insulating ducts, especially those in unconditioned spaces such as attics or basements, aid in maintaining cooler air and preventing energy wastage. Addressing leaks and insulating ductwork ensures efficient distribution of cool air throughout the house, enhancing the overall efficiency of the air conditioning system.

6. Reduce Heat Gain Inside Your Home

Reducing indoor sources of heat will make the AC work more efficiently. Use curtains, blinds, or window films to block excess sunlight. This helps to lower temperatures indoors, which subsequently lightens the burden on the AC. Consider using heat reduction window treatments that are energy efficient, which help maintain a cool temperature within the house. Appliances like ovens, dryers, and stoves emit heat. If possible, do these chores during the cooler hours of the day. Circulating air using ceiling fans also aides in cooling down the house, thereby lightening the load on the AC. Replacing incandescent light bulbs with LEDs is one more good way to reduce heat in the house, as they expel less heat.

7. Optimize Airflow with Proper Ventilation

Proper airflow is essential for an air conditioner to function efficiently. Keep vents unblocked by furniture or curtains to ensure even distribution of cool air. Additionally, using exhaust fans in kitchens and bathrooms helps remove excess heat and humidity, reducing the workload on your AC unit. Poor ventilation can cause stagnant air and uneven cooling, leading to discomfort and higher energy use. If necessary, consider installing an attic ventilation system to expel hot air and prevent heat buildup in your home. Keeping doors between rooms open can also improve airflow, allowing for better air circulation throughout your living space.

8. Upgrade to an Energy-Efficient Model

If your air conditioner is more than 10-15 years old, it may be time for an upgrade. Older units tend to be less efficient and may struggle to maintain optimal cooling performance. Modern air conditioning units come with improved energy efficiency ratings (SEER ratings) and advanced technology that reduces power consumption. Investing in an energy-efficient model can lead to significant savings on your electricity bill in the long run. Look for units with inverter technology, which allows the compressor to adjust its speed according to cooling demand, leading to better efficiency and reduced wear and tear. Additionally, government rebates or incentives may be available for upgrading to an energy-efficient air conditioning system.
