Why insulating your house while running the AC is crucial in the summers

Did you know that 25% of your home’s cool air leaks through small cracks and holes in the summers? Even though your air conditioning (AC) system continues to work, you constantly waste energy and money.


Below are four reasons why you need to ensure that your home is properly sealed and insulted while running the AC:


1.    The Stack Effect

Also known as the chimney effect, the stack effect is reversed in the summers since warm air lies outside. Cool air inside falls and gets pushed out at the bottom, causing hot air to enter at the top.


Air sealing can slow down this process as it prevents air leaks, allowing the HVAC (heating, ventilation, and air conditioning) equipment to work efficiently and keep the cool air within the house.


2.    Air Sealing Around Piping

When your home is air sealed and well insulated, the temperature indoors will remain naturally lower and consistent.


Air sealing around piping, wiring, and plumbing vent stack pipe penetrations in the attic will seal up existing air leaks, keeping the upper floors cooler during summers.


3.    Air Sealing Attic Wall Plates

Air leaks in the attic can be responsible for substantial loss of cool air, which is why it is a favorite starting point of insulation for many homeowners.


By air sealing the tops of interior wall plates, there will be less air movement in the upper floor walls between conditioned and unconditioned areas of the house. Your house will stay cool longer and you can save energy.


4.    Air Sealing Exposed AC Duct

An exposed accessible AC ductwork will warm the cool air in your home bit by bit.


Air sealing this, whether in the attic or the basement, will improve the cool air CFM (cubic feet per minute) flow to the registers, hence keeping your electricity costs low.
