Nicor Gas Program Approved Contractor

Air sealing, duct sealing and attic insulation.

We work through the Nicor Gas Energy Efficiency Program's Air Sealing and Insulation offering. If you are a Nicor Gas customer, air sealing and duct sealing are performed at no cost to you. No income requirement, nothing out of pocket. Attic insulation is quoted separately.

What We Do

Three services. One trade.

No cost to Nicor customers

Air Sealing

Sealing the gaps where conditioned air leaves the house and outside air gets in. Most of the loss is in places you never see.

  • Attic floor penetrations and top plates
  • Rim joist and sill plate
  • Around plumbing, wiring and ductwork chases
  • Doors, windows and access hatches
No cost to Nicor customers

Duct Sealing

Sealing supply and return ducts running through unheated space, so the air your furnace pays to heat reaches the rooms you live in.

  • Ducts in attics, crawlspaces and unfinished basements
  • Joints, seams and connections at the plenum
  • Disconnected or damaged runs identified
  • Mastic and foil-backed tape, not cloth duct tape
Quoted, free estimate

Attic Insulation

Bringing under-insulated attics up to depth. This one is quoted rather than covered, and Nicor rebates apply. We handle the paperwork.

  • Blown-in insulation over existing
  • Baffles and ventilation checked first
  • Air sealing completed before insulating
  • Free estimate, no obligation
How This Gets Paid For

There is no income requirement.

The sealing work is funded through the Nicor Gas Energy Efficiency Program. Nicor pays the approved contractor directly, so nothing is billed to the homeowner. The one requirement is that the home is a Nicor Gas customer.

No cost

Air sealing & duct sealing

Covered in full by the program for Nicor Gas customers. This is not a rebate. You don't pay us and claim anything back later. There is no income test, no application, and no invoice at the end. Nicor pays us directly for the work we complete.

All we need is confirmation that the address is on a Nicor Gas account. We check that ourselves, so you don't send us documents.

Quoted

Attic insulation

Insulation sits outside what the program covers in full, so this one is priced. Nicor rebates for insulation reduce what you pay, and because we're a program approved contractor the work qualifies. We file the rebate paperwork.

Free estimate, no obligation. Rebate amounts are set by Nicor and change year to year, and we'll tell you the current figure before you decide.

How It Works

Four steps, start to finish.

Step 01

You reach out

Call or send the form. We take your address and the name on the Nicor account, and confirm the property is in our service area.

Step 02

We confirm the account

We check that the address is served by Nicor Gas. That's the only requirement, and we handle the check ourselves.

Step 03

We schedule the job

We book a date that works for you. There is no separate assessment visit. The crew comes out to do the work.

Step 04

The work gets done

Sealing is usually finished in a single visit. If you've asked about insulation, we quote it while we're there.

The Company

Who we are.

American Construction Group is a licensed and fully insured contractor working under the Nicor Gas Energy Efficiency Program. Based in Villa Park, we focus on one part of the trade: finding where a house is losing air and closing it up.

Air sealing done properly is careful, unglamorous work. It depends on knowing where the leaks hide in the housing stock around here, and on crews who do it every day rather than as a sideline to remodeling.

We work on single-family homes, multifamily buildings and rental properties, and we're approved for both the sealing and the insulation side of the program.
