Air Conditioning or Windows: Which is Better?

Air Conditioning or Windows: Which is Better?

For many people, there's nothing like the fresh air windows can bring into a home, something even HVAC professionals can enjoy! But what if that same air is hot and humid? This is when air conditioning can be very much appreciated. Ultimately, it doesn't have to be one or the other when it comes to air conditioning and the air that comes in from windows.

Now, you would think that any HVAC professional would wholeheartedly be in favor of air conditioning. However, we're an HVAC service provider that keeps customer needs front-and-center at all times. For this reason, we're going to give you an honest answer for which is better.

Opening Windows

HVAC professionals can also appreciate opening windows on cooler summer days to save energy by not having to run the HVAC system or turn on air conditioning units. Plus, if your home is an area where there's natural shade from trees, opening the windows can be the perfect way to keep your home naturally cool and comfy.

Opening windows strategically can also be a good way to minimize HVAC and air conditioning costs. For instance, you might open your windows in the morning when it's cooler, turn on your HVAC system when it gets hotter and more humid later in the day, and switch off the AC later if it gets cooler outside again.

Some homeowners also find it helpful to place fans on high shelves to make the most of the fresh air windows let in. Also, there are many health benefits associated with opening windows that both HVAC professionals and homeowners can appreciate, such as:

  • Fresh, oxygen-rich air
  • The possibility of a reduced cancer risk from bringing more oxygen inside
  • Reduced exposure to indoor air pollutants

Using Air Conditioning

Contrary to popular belief, relying on air conditioning more often than open windows doesn't necessarily mean you'll be using more energy to re-cool and circulate air throughout your home. A well-maintained HVAC system, for instance, can be highly efficient even when used often.

Also, if your home is exposed to direct sunlight or in an area where humidity and heat are more of a concern, opening windows can be counter-productive. In other words, you'll just be bringing all that heat and humidity from the outside into your home. In this case, it makes more sense to generally rely on AC during the hot, humid summer months and wait until things cool down in the fall to open your windows.

It can also be better to leave your AC on even as the sun goes down when it's still humid outside. Yes, turning off your HVAC system cuts energy costs by about 30 percent. But if it's a hot, humid night, the extra moisture coming into your home could make your cooling system work harder during the day to get rid of all that extra humidity. Air conditioning can also beneficial health-wise when:

  • There's a sensitivity to outdoor allergens that could get in through open windows
  • You or someone in your household has respiratory issues affected by humidity
  • A more consistent indoor climate improves physical and mental comfort
