Air Conditioning or Windows: Which is Better?

For many people, there's nothing like the fresh air that windows can bring into a home. It's even 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. It doesn't have to be one or the other. When it comes to air conditioning and the air that comes in from windows, there isn't a bad option.

You would think that any HVAC professional would be in favor of air conditioning. 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 appreciate opening windows on cooler summer days. This can save energy by not having to run the HVAC system or turn on air conditioning units. This is especially true 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 cool and comfy.

Opening the right windows can also be a good way to cut HVAC and air conditioning costs. You might open your windows in the morning when it's cooler. Then, turn on your HVAC system when it gets hotter and more humid later in the day. Switch off the AC later if it gets cooler outside again, such as in the evening.

Some homeowners also find it helpful to place fans on high shelves to make the most of the fresh air windows let in. There are many health benefits associated with opening windows. Both HVAC professionals and homeowners can appreciate these benefits, 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

Relying on air conditioning more than open windows doesn't mean you use more energy. Your HVAC system is there to cool and circulate air throughout your home. A well-maintained HVAC system can be efficient even when used often. The best way to maintain your system is to have regular checks and maintenance on your system.

If your home is in direct sunlight or an area where humidity and heat are more of a concern? Open windows can be counter-productive. In other words, you'll be bringing all that heat and humidity into your home. In this case, it makes more sense to rely on AC during the hot, humid summer months. 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. On a hot, humid night, the extra moisture in your home makes your cooling system work harder. This is more true during the day, working 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
