In order to stay comfortable this summer without having the pay a high price (heating and cooling is the largest energy expense), you should inspect your home for air leaks and seal them up before summer. Cool air leaking out and warm air leaking in (vice versa during winter) can waste a lot of money and energy.
Now is a great time to make sure your home is properly sealed and insulated, such as air sealing and insulating your attic.
When searching around your home for air leaks, use this useful air leakage map from energy.gov as a guide:

While it’s a good idea to maximize your home’s energy efficiency, you must be careful not to over-insulate your home. An airtight home is prone to higher levels of indoor air pollution, such as harmful gases and volatile organic compounds. While it may seem that the air inside your home is cleaner than the air outside, microbial pollutants like pet dander, mold, and pollen can build up in your home, creating a toxic environment “where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations” (EPA).
If you have an airtight home, you may spend less on heating and cooling, but your air won’t be very healthy. That’s why energy-efficient homes should have a whole-house balanced ventilation system.
After caulking, weatherstripping, and insulating your home, speak with a trusted HVAC professional to make sure you have proper ventilation levels for healthy indoor air quality. If you have any questions about sealing and insulating your home, don’t hesitate to Ask a Champion.
