Seal and Insulate the Home Envelope to Keep Conditioned Air Indoors

- Published by

When you think about home comfort, your first thought is probably cooling. But most homeowners think about the air conditioner first, and how much energy it takes to get a house cool. You might not think about how best to keep your home cool, but if you seal and insulate your home envelope, you can see cooling costs fall just like you would if you upgraded to a more efficient A/C!

Your home’s thermal envelope is the barrier between the indoor temperature and the outdoor temperature. This includes walls, windows, roofs, floor insulation and pretty much anything else that keeps cool indoor air indoors. Here are four steps to improve, seal and insulate your home envelope:

  1. Call in the professionals for an energy audit. Before going at the windows with a caulk gun and the walls with new insulation, they will determine where you’re actually losing energy. Some homes might have an attic that needs insulation and ventilation, while others might lose the most energy because of solar heat gain. Learn your problem spots so you know where to improve.
  2. Find air leaks through your home and seal them. These might be windows that don’t seal properly or even damage to the walls. If you prevent inside air from getting out and outside air from getting in, your thermal envelope will be stronger.
  3. Insulate! You might not think a Florida home needs much insulation, but insulation also keeps heat out. Ask your contractor if your home meets the official insulation recommendations.
  4. Upgrade old and inefficient windows and doors. These are traditionally big gaps in your thermal envelope, but they don’t have to be! Windows can be upgraded to insulated glass or treated with reflective films or other window treatments, while doors can be upgraded to better-insulating materials and fitted with door sweeps to prevent airflow.

6/4/2026 Alan and Logan were here today to do our 6 month check up. They were on time, efficient, polite and knowledgeable. Nice to have a company I can depend on for great service. 1/20/2026: Allen and Michael from Scotts Heating and Air were just here for our 6 month maintenance on our HVAC and they were excellent. Polite, Friendly, On Time and Efficient. We greatly appreciate everyone from Scott's Heating and Air who have been to our house!! We had to have our entire HVAC replaced and Craig really worked with us to get us a fair price and arranged 1 year 0% financing. We got scheduled very quickly and Boris, the installer, could not have been better. He was exactly the type of service person we want in our house. He and his team were polite and meticulous. They cleaned up the job site when it was completed. Once the install was complete Boris was very good and explaining our system to us and left us with complete confidence of a job WELL DONE! ......... Fantastic service and was able to schedule for the next day. Anthony was thorough and explained everything he did. He was extremely polite and efficient. The receptionist who scheduled my appointment was also very polite and easy to work with. I highly recommend Scott's Heating & Air Conditioning.
