Why won't my AC ever cool down my house!?

August 12, 2019

Now that the summer weather is full-blown hot and sticky, it’s the time of year your Wisconsin home most needs to keep cool. But if your AC keeps running and running without cooling down your house, there may be a problem with your home’s performance – more specifically, your home may have air leaks or inadequate insulation. 

Though the first instinct is to upgrade your central air, the cause of your lukewarm interior may lie in your home's ability to manage the flow of energy. And that's the key to staying comfortable all year long!

Your Leaky Home Could be Costing You

If your home feels drafty or can't seem to stay cool in the summer, your house is probably leaking air through hundreds of tiny gaps, cracks and holes in the walls, ceiling, and floor. When added up, these gaps can leak the equivalent of the amount of air you’d lose by leaving a window open all year long. Leaks can also impact indoor air quality making family members uncomfortable, or aggravating asthma or allergy symptoms. No wonder your AC can’t keep up! 

Symptoms of a leaky house include:

  • Drafty rooms

  • Rooms that are too hot in summer or too cold in winter

  • Increased allergy symptoms

  • Mold or mildew

It All Starts with a Home Performance Audit 

The best way to identify the cause of problems in your southeast Wisconsin home is to schedule a complimentary home energy audit by the pros at Wisconsin Home Improvement. Using proven building science and specialized tools, your WHI energy auditor will pinpoint where tiny gaps and cracks are located. Using an infrared thermal scanner, we’ll also be able to “see” behind walls to spot places where insulation is missing or deficient.

Upgrade Insulation to Cool Without AC

Insulation works best when combined with air sealing to keep the sun’s radiant heat from sapping your cool inside air, and preventing that cool air from escaping through leaks. Your home insulation acts like a cozy sweater to keep your interior warm. Combining insulation with air sealing is like adding a windbreaker to keep air from passing through the sweater. The same effect works in the summer to keep cool conditioned air inside your home. Many homeowners discover they can decrease the amount of central air needed to keep comfortable when they upgrade their home’s insulation.

New Insulation Saves Money 

We start at the top – where the impacts of radiant heat from the sun and the potential for air leakage through unfinished spaces like the attic is most pronounced. Starting with attic insulation, our energy team will first air seal, then install insulation to keep your home comfortable and reduce the flow of energy in and out of your house. As a Owens Corning Certified Energy Expert, we will ensure your high performance attic insulation is properly installed. Another area that benefits from upgrades for summer coolness is floor insulation. Applying a radiant barrier sealing and insulation to the floor protects living areas from energy loss and prevents the transfer of moisture. Upgrading your home insulation and air sealing can work together to save as much as 40% off your energy bill!
