air conditioning mistakes

This Summer

As temperatures rise, ensuring your air conditioning system is operating efficiently becomes paramount. However, many homeowners inadvertently make mistakes that can compromise the performance and longevity of air conditioning systems during the summer months. To help you keep your home cool and your energy bills in check, here are summer air conditioning mistakes to avoid.

Neglecting Regular Maintenance

Regular maintenance is crucial for the efficient operation of your air conditioning system. Skipping routine tasks like changing air filters, cleaning coils, and checking refrigerant levels can lead to decreased efficiency, higher energy bills, and premature system failure. Schedule routine air conditioning maintenance to ensure proper system performance.

Setting the Thermostat Too Low

Setting your thermostat to an excessively low temperature won't cool your home any faster. Instead, it forces your system to work harder and longer, consuming more energy in the process. Set your thermostat to a comfortable temperature and resist the urge to crank it down. Consider installing a programmable or smart thermostat that allows you to schedule temperature adjustments based on your lifestyle for greater energy saving.

Blocking Airflow

Blocked vents and registers restrict airflow, causing uneven cooling throughout your home and putting unnecessary strain on your air conditioning system. Ensure all vents and registers are clear and unobstructed to maximize airflow and efficiency. Blocking the condenser unit with tall grass, shrubs, or other objects also restricts airflow and reduces the efficiency of your air conditioning system. Keep the area around the condenser unit clear and free from obstructions to maximize airflow and cooling efficiency.

Ignoring Leaks or Duct Damage

Leaky ducts or damaged ductwork can result in cooled air escaping before it reaches its destination, leading to energy waste and reduced comfort. Have your ducts inspected regularly and seal any leaks to improve efficiency and airflow.

Running the HVAC System with Windows or Doors Open

Running your air conditioner with windows or doors open is like throwing money out the window. Keep windows and doors closed when your system is running to prevent cooled air from escaping and hot air from entering, maximizing energy efficiency.

Neglecting Ceiling Fans

Ceiling fans can complement your air conditioning system by circulating air and improving comfort. Set your ceiling fans to rotate counterclockwise during the summer to create a cooling breeze that allows you to set your thermostat higher without sacrificing comfort.

Using the Wrong Sized System

One of the most critical factors in HVAC system efficiency is selecting the right size unit for your home. An oversized system may cool your home quickly, but it will cycle on and off frequently, leading to increased wear and tear, higher energy bills, and inconsistent temperature control.

An undersized system will struggle to keep up with cooling demands, running continuously and driving up energy costs. To ensure optimal performance and efficiency, consult with a qualified HVAC professional to properly size your system based on your home's size, layout, insulation, and climate conditions. Investing in the right-sized system upfront can save you money and frustration in the long run, providing reliable comfort and energy savings for years to come.

Skipping Professional Air Conditioning Repairs When Needed

Attempting to troubleshoot and repair air conditioning issues without the necessary expertise can lead to further damage and costly repairs. If you encounter problems beyond your skills, don't hesitate to call a professional technician for assistance.

Delaying Air Conditioning Replacement When Necessary

If your air conditioner is old, inefficient, or constantly in need of repairs, delaying its replacement could end up costing you more in the long run. Upgrading to a newer, more energy-efficient model can lower your energy bills, improve comfort, and reduce the likelihood of breakdowns.
