Energy Audits and Insulation: What to Know Before You Upgrade

Upgrading your home’s insulation is one of the most effective ways to improve energy efficiency and comfort. But before you rush into installing new insulation, there’s a critical first step that many homeowners overlook—getting an energy audit. This assessment can pinpoint where your home is losing energy, helping you make smart, cost-effective decisions about where and how to insulate.

At Koala Insulation of Northern Illinois, we work with homeowners to maximize comfort and savings by combining professional energy audits with expert insulation services. Here’s what you need to know before upgrading your insulation.

What Is an Energy Audit?

An energy audit—also known as a home energy assessment—is a comprehensive inspection that identifies areas of energy loss in your home. A certified technician evaluates your HVAC system, insulation levels, windows, doors, and more, using tools like infrared cameras and blower door tests to detect leaks, gaps, and inefficiencies.

This detailed assessment helps you understand how your home uses (and loses) energy, providing a clear picture of the improvements that will deliver the greatest return on investment.

Why Schedule an Energy Audit Before Upgrading Insulation?

Insulation upgrades can be costly, especially if done without a plan. An energy audit ensures you’re targeting the right areas for improvement. Here’s why you should prioritize the audit:

1. Pinpoint Problem Areas

Many homes suffer from energy loss in hidden areas like crawl spaces, attics, or behind walls. An energy audit identifies the exact spots where insulation is lacking or failing, so you don’t waste time and money on unnecessary work.

2. Measure Air Leakage

Insulation alone won’t solve efficiency issues if air sealing is ignored. An energy audit measures air leakage, helping determine whether your home needs air sealing along with insulation, especially in attics, basements, and around ductwork.

3. Prioritize Upgrades

Rather than replacing insulation everywhere, an audit allows you to prioritize upgrades based on effectiveness. This is especially helpful for older homes or if you’re working with a limited budget.

4. Boost Rebates and Incentives

Many utility companies and local governments offer rebates and incentives for insulation upgrades—but often require a certified energy audit first. Working with Koala Insulation of Northern Illinois ensures your upgrades are eligible for maximum savings.

How Energy Audits Work

A professional energy audit involves several steps to ensure thorough analysis. When you work with Koala Insulation of Northern Illinois or one of our partners, here’s what to expect:

● Initial Consultation

The technician will ask about your utility bills, comfort issues, and any specific concerns you’ve noticed—like drafts or rooms that are hard to heat or cool.

● Visual Inspection

This includes checking insulation levels in the attic, basement, and walls, examining HVAC ducts, inspecting window and door seals, and identifying obvious leaks or damage.

● Blower Door Test

This test lowers the air pressure inside your home to reveal leaks. The technician can then use infrared cameras or smoke pencils to track where air is escaping.

● Thermal Imaging

Using infrared imaging, the technician will visualize areas of heat loss or infiltration, clearly showing where insulation is missing or ineffective.

● Detailed Report

After the inspection, you’ll receive a report outlining problem areas, recommended upgrades, and estimated energy savings from each improvement.

What to Know About Insulation Upgrades

Once your energy audit identifies where to insulate, it’s time to choose the right material and method for the job. Koala Insulation of Northern Illinois offers a range of options to match your home’s specific needs and budget.

● Spray Foam Insulation

Best for sealing air leaks and providing a high R-value in tight spaces. Spray foam is ideal for attics, crawl spaces, and around ductwork.

● Blown-In Insulation

An excellent choice for attic floors or wall cavities, blown-in fiberglass or cellulose is cost-effective and can be added over existing insulation.

● Batt Insulation

This is a popular option for walls and ceilings in unfinished areas. Fiberglass batts are easy to install and provide solid thermal performance.

● Air Sealing

In many cases, adding insulation alone isn’t enough. Our team can provide professional air sealing services to stop drafts and heat transfer before installing new insulation.

When to Schedule an Energy Audit

You don’t have to wait for a home improvement project to schedule an energy audit. It’s a good idea if:

• Your energy bills are unusually high
• Some rooms are hotter or colder than others
• You’re planning to upgrade your HVAC system
• You live in an older home with original insulation
• You’ve never had your home’s energy efficiency tested

Whether you’re preparing for a major renovation or just want to improve day-to-day comfort, an audit is the best first step.
