Why Your Air Conditioner Performs More Efficiently In Spring & Fall

Bi-County Inc Increase AC Efficiency

Outside Temperatures Affect How Well Your HVAC Works

We all know that the hotter it is outside, the harder the AC works to cool our homes. As a result, you might find it struggling to bring down temperatures in extreme summer heat. One reason is that the air conditioning cycle requires the temperature outside to be cooler than the hot air it is releasing from the unit. That is why your air conditioner works more efficiently in cooler fall and spring temperatures. One of the simplest ways to increase the efficiency of your HVAC is regular maintenance services. Dirt and debris, or faulty parts can add to the strain on the compressor.

The Science Behind This Common-Sense Phenomenon:

  • Thermodynamics #1: Simply put, your AC is a heat exchanger which moves hot air from one place to another. According to the laws of thermodynamics (the science of heat transfer) this is accomplished by working to bring equilibrium between two opposing temperatures. This explains why there is heat gain inside through the walls, roof, windows and doors when it’s hotter outside.
  • Thermodynamics #2: To remove the hot air from your home, the AC uses the second law of thermodynamics which states that heat naturally flows from a hotter to a cooler object. Since the amount and rate of heat transfer depends on the temperature difference, the air conditioner is more effective when the air outside is cooler. Keeping the outside unit shaded can help this process.
  • Refrigerant Cycle: The AC circulates refrigerant to cool the air in your home. As hot air flows over the cold evaporator coils, the refrigerant absorbs heat and changes from a liquid to a gaseous state. The AC must convert the refrigerant gas back to a liquid to continue this cooling cycle. So lower outdoor temperatures make its work easier.

Schedule a Tune-Up to Increase the Efficiency of Your HVAC System

An annual AC system checkup and cleaning can help identify and fix small issues, so you can avoid a sudden breakdown at the peak of summer. Studies show that without an annual tune-up, your HVAC system can lose up to 5% efficiency every year. Here are a few simple steps to keep your home cooling system running smoothly:

  • Remove Debris from Around the System: Before you remove the AC cover, clear the surrounding area of any branches, dead leaves and debris.
  • Clear the Drain Pan: Over time, mold and algae can accumulate in the drain pan. A plugged drain can damage the system as well as cause a flood.
  • Clean the Fins: Use the brush attachment on your vacuum to clean the fan cage before you take it off. Vacuum any dirt that may have collected inside the unit. Then gently clean the fins with a brush, taking care not to damage them.
  • Change the Filters: Check your furnace blower filter and change it if it is dirty. This keeps dust from accumulating in the evaporator coil fins.

When your air conditioner is cleaned, maintained and ready for use, the air quality inside your home improves too. Rest assured, each of Bi-County’s certified technicians is qualified to help you optimize AC unit efficiency to help maximize the lifespan of the system. We can identify any potential issues and advise you about what might need attention in the future, so that you don’t have to deal with constant nuisance repairs.
