The Cool Summer Benefits of Insulation

Making sure your home is properly and adequately insulated is the single best thing you can do to reduce your energy bills and increase cooling efficiency.If your home isn’t properly insulated, that sneaky warm air inconspicuously entering your home changes the internal temperature, forcing your HVAC to work a lot harder to keep the house cool—especially if your HVAC system is located in your uninsulated attic. If this is the case, your HVAC has to work extra hard to keep cool in a steamy attic and your home ends up suffering from major cooling loss. Making sure your home is properly and adequately insulated is the single best thing you can do to reduce your energy bills and increase cooling efficiency.
A good insulation job can reduce the cost of heating and cooling by a whopping 40%.While it can seem cost prohibitive to install, replace, or upgrade insulation, the return on investment will be well worth it. A good insulation job can reduce the cost of heating and cooling by a whopping 40%. Of course, in the spirit of cooling efficiency and energy conservation, you’ll also want to consider home window replacement to ensure that no outside air is entering through improper seals and thin single panes. Together, these home improvements can dramatically extend the lifespan of your HVAC system and save you big when it comes to summer cooling costs.
Getting Summer Benefits: Where Insulation Should Be Installed
I’ve done a lot of insulation inspections in homes all around Northern California and I often get asked if insulation should be ripped out and completely replaced. If the insulation is fiberglass, it typically doesn’t need replacing; if it’s in good shape, it can last up to 100 years if properly installed. In that case, I just make sure the attic is insulated and leave things as they are. If a house is insulated with loose insulation like cellulose or vermiculite, or some key parts of the house aren’t insulated, though, work may need to be done to increase the cooling efficiency and energy savings in your home. You could be making extra work for your HVAC system if you have aging insulation—or you don’t have any insulation—in the following places in your house:- The attic or ceiling: An uninsulated attic in the summer is like an oven heating up the rest of your home from the top down. Insulation can reduce how hot it gets up there but, more importantly, it prevents heat from spreading to the rest of the house, resulting in a 20-60% energy savings.
- Interior walls: Keeping hot air from transferring between rooms helps maintain a cooler internal temperature throughout your house and your HVAC system won’t have to work nearly as hard to keep your house cool.
- Around ductwork: If your ducts pass through a hot attic or an outside wall, you’re losing precious cool air. Insulating your ductwork can help prevent this and significantly lessen the load on your HVAC unit, which equates to lower energy bills.
- Garage walls: Similar to attics, uninsulated attached garages heat up like crazy in the summer—and the heat can transfer into your home. While you can certainly insulate all four walls of a garage, even just insulating the wall shared with your interior living spaces can make a big difference in your home’s overall efficiency.
- Windows and doors: Fixing or filling any cracks and spaces between walls and window or door frames can prevent hot summer air from heating up your cool home oasis. You’ll also want to consider installing vinyl windows to achieve the tightest seal possible.
Proper installation is also essential to ensure achieving maximum cooling efficiency and energy savings in your home after adding insulation; it’s vital to hand the job over to an experienced professional.Proper installation is also essential to ensure achieving maximum cooling efficiency and energy savings in your home after adding insulation; it’s vital to hand the job over to an experienced professional.
