Here in Georgia, we rely heavily on our HVAC units – specifically the cooling units or air conditioners in our homes. Let’s take a look at how you can both keep an eye on and boost your HVAC systems’ energy efficiency this year.

Seven Factors That Impact Your HVAC System’s Efficiency

1 – Poor Insulation & Drafts

Much like with the windows and doors in your home, if you have drafty areas – like up near rafters or under the basement door – that allow cooled air or heat to escape, you’re essentially letting money leak through the cracks. Conditioned interiors cost quite a bit of money to maintain, and if you want peak efficiency, be prepared to do a full audit of your Atlanta home’s weak points.

2 – Old Windows & Doors

Homes and businesses are meant to be tiny bubbles within the outside environment. The more inefficient your home is, the more inefficient your HVAC systems will be. You can make significant improvements to energy and fuel efficiency by replacing old, drafty, poorly-insulated doors and windows in your home or business. The cost might be hefty upfront, but the savings on electricity and fuel (plus the bonus to resale value) make up for the cost.

3 – Low or Fluctuating Humidity

Many people forget that humidity is part of interior air conditioning (whether that’s cooled or warmed air). In fact, by increasing the humidity in your home during the winter, you can reduce your fuel usage simply because moist, warm air feels warmer than dry, warm air. Similarly, in the summer, ensuring that your interior humidity stays low, your air conditioning efforts will go much further.

4 – System Age

Like with any piece of machinery, efficiency decreases with age. In addition, newer machines tend to use newer technology, making their base efficiency higher. If you have an older HVAC unit and there don’t seem to be any other confounding variables, it might be time to replace your furnace or air conditioning unit.

5 – Poor Maintenance

Expensive machines are expensive to replace, but you can reduce the likelihood of costly repairs or replacements simply by keeping up with your unit’s maintenance. Have your air conditioning unit serviced yearly and your furnace serviced yearly, as well – even if you don’t run it that often during the winter months.

6 – Dirty Filters

Unfortunately, dirty filters can both hinder airflow through your unit and can be a source of odor and mold for the entire ventilation system. Change your air filters every month (some filters can last longer) for maximum efficiency and minimal negative effects.

7 – Dirty Ductwork & Poor Circulation

While you can’t necessarily see into these vents to check their cleanliness, a professional with a scope can. Dirty ductwork, like dirty filters, can build up mold, dust, pet hair, pet dander, and cause restricted airflow through your system – and odors to build up and circulate needlessly. 


As part of a regular audit of your system, an HVAC specialist will be able to check the status of your air ducts. At this time, any leaky or dirty ducts can be patched, cleaned, or replaced if necessary.

If you notice that your ventilation system seems to be underperforming, it’s time to call a professional.
