Save money and keep your home healthier and more comfortable with complete home performance services from Althoff Industries

By using the “home as a system” approach, our service addresses all aspects of your home’s efficiency, safety, air quality and comfort. Get the most out of your mechanicals, protect your family, secure the investment in your home, stay more comfortable and make your dollar go further by scheduling a whole-home diagnostic today. Every home is composed of a series of interacting systems. The auditing process surveys these systems and verifies they are interacting/functioning as designed. Misalignment of these systems can be harmful both to your family and home.

Do you have any of the problems below?

  • Your mechanical system never seems to shut off
  • Areas of your home are always uncomfortable
  • Mold has been identified within your home
  • Pipes have frozen or burst in the past
  • Significant ice damming formations
  • You’re concerned about the quality of the air within your home

A blower door will be utilized to better determine where and how well your home is connected to the outside and will be run in conjunction with an IR camera. Doing so will permit the auditor to visually see where and how well your home is sealed from the outside.

Most homes experience this exchange of air, and subsequently energy, in an undesigned fashion. This means that your home is losing conditioned air — and money — constantly.  Moreover, this unplanned transmission of conditioned air makes your mechanicals work harder. All homes need some amount of fresh air, but the fresh air should be introduced in a controlled manner.


Insulation is, in large part, what helps to maintain acceptable levels of comfort within your home. The materials used are given an R-value that communicates how resistant they are to the transmission of heat, meaning how much heat, or energy, can pass through it. 


Air sealing is the other half of improving the comfort and efficiency of your home. It’s estimated that 5– 40% of annual heating and cooling costs are due to the leakage of conditioned air out of your home. Air sealing is one of the most effective efficiency upgrades you can make to your home. By reducing the amount of conditioned air that is lost, you’ll be saving money, improving comfort throughout your home and causing your mechanicals to wear less.

Our team of technicians, each certified by the Building Performance Institute and ENERGY STAR® Home Performance – will pinpoint trouble areas and help you decide how best to address them.

Up to $400 in utility rebates available for air sealing and insulation services.

 Air Sealing

Don’t pour money out the window (or through your floor or ceiling) – keep your home draft-free with air sealing services from Althoff Industries

As anyone who’s survived a Chicago winter can attest, drafts can make a home downright uncomfortable in winter.

But air leaks are problems all year around. In fact, cool or hot air lost from your home can raise your energy bills by as much as 40 percent, while carrying odors, moisture and air contaminants from room to room. And without air sealing to stop leaks, insulation doesn’t work very well, either, making the problem even worse.

Although some problem areas are easy to spot – untreated doors and windows, for example – much of your homeʼs air leaks take place in areas you don’t see.

But Althoff Industries’ experts will spot them.

Whatever the cause, our courteous, highly trained technicians will track down your home’s air leaks and seal them. Weʼll test everywhere, from your crawlspaces and attic to recessed lighting – even your walls and ceilings.

With quality air sealing work from Althoff Industries, you can expect significant energy savings. And, because materials are relatively inexpensive, you’ll find sealing work to be one of the most cost-effective solutions for the energy performance of your home.

For a free estimate on air sealing for your home, contact Althoff Industries today at (815) 455-7000.


Duct Cleaning

Keep your indoor air clean and your family healthy with duct cleaning services from Althoff Industries

Did you know that the Environmental Protection Agency ranks indoor air pollution among the top five environmental dangers to the public – and that dirty air duct systems cause two out of three indoor air quality problems?

Because air ducts are breeding grounds for the mold, fungi and dust mites that cause infections and allergic reactions, cleaning them is critical to your family’s health.

That’s why Althoff Industries’ team of duct cleaning experts will scour all of your ductwork and inspect and clean your furnace and air conditioning units. We’ll do it quickly, too, with no mess and always with the highest standard of professional courtesy.

Once we remove the allergens from your ducts – along with residue from cigarette smoke, pet hair and other contaminants – you’ll breathe easier knowing you’ve taken the steps you needed to protect your family’s long-term well-being.

Let Althoff Industries help you clear the air. Call us at 815-455-7000 to learn how duct cleaning can keep your family safe and healthy or call 815-455-7000.



Save money and stay comfortable in every room, every day with insulation services from Althoff Industries

Because insulation keeps heat in during the winter and blocks heat out during the summer, it is one of the most cost effective ways to improve the energy efficiency and comfort of your home.

Working with the latest in dense-packing and loose-filling cellulose products, Althoff Industries’ experts will provide insulation solutions that are nontoxic, environmentally responsible, mold, mildew, fire and pest resistant.

Of course they’ll also stop drafts and maximize the effectiveness of every square foot of insulation we install – and with additional services like our home energy audits and air-sealing solutions, we can find even more ways to fix your home’s problem areas.

To learn how better insulation can save you money and keep your family more comfortable year-round, call us at 815-455-7000.
