Home Insulation & Air Sealing Company

Many homeowners are under the impression that their home is properly insulated. However, when we take a look we find that the majority of homes do not have the proper amount of insulation. We find the wrong types of insulation used, insulation in the wrong locations, gaps in the insulation and in some cases no insulation at all. What does that all mean? It means you are spending far more money than necessary to keep your home comfortable. Stop wasting money, contact the professions at Halco today!

The idea of home insulation has been around for centuries. Cavemen lived in caves because of the natural protection it afforded them. Modern dwellings do not naturally keep the inhabitants warm and comfortable, insulation must be added to get the job done. Pink fiberglass insulation was used for decades but now Polyurethane spray foam is the best product available.

Benefits of Spray Foam Insulation Include:

  • spray foam works in all areas of the home
  • has a greater R-value
  • acts as an air sealant
  • is waterproof
  • leaves no gaps

By adding additional attic insulation, you will make your home more comfortable and save money on your energy bills.

We all know that heat rises and as a result attic insulation can have a major impact on the efficiency of your home. When you are heating your home in the colder months that heat will rise and escape through your attic. Depending on the size of your home the amount of heat that will escape could be equivalent to keeping a window open.

In a national study, the average R-value found in an average attic is R-19 while the U.S. Department of Energy recommends an R-value between R-49 and R-60. Halco has the trained professionals who will be able to give you certainty about the attic insulation in your home and its overall efficiency. Call or click today to Save up to 20% or more in heating and cooling costs with a properly insulated attic!

We recently purchased this house and have not had the furnace serviced as yet. There are multiple thermostats which we may be interested in replacing. Also there is a gas non vented fireplace that the previous owners used as part of their heating system, which we don't know anything about so it would be helpful if the service person could explain how it operates and how we can control it.

I had a problem with an inducer, which was supposed to be under warranty, but failed after only two years. I have called the Phelps and Romulus offices, and the responses have varied, but mostly have been that they will look into a reimbursement from Heil. Carissimi Plumbing originally installed the furnace, but Halco did replace the part and took the original. Please give me a response regarding this matter. Thank you.
