Minnick’s knows that in order for your heating and air conditioning systems to do their job, they need help in the form of insulation. The insulation that we recommend takes two forms: spray foam and cellulose. Our technicians will visit your home to determine what type of insulation you currently have, and if it should be removed. Minnick’s installs two types of insulation, spray foam and cellulose.





Air sealing is one of the most important – yet little known – building performance improvements around. Performing air sealing can lead to improved comfort, lower energy bills, and a more environmentally-friendly home.

What is Air Sealing?

Air sealing is pretty much what it sounds like – sealing the hidden air leaks in your home. Unresolved air leaks are often compared to leaving a window open all year round, because they can lead to drafts, cold spots, wasted air conditioning, discomfort, and increased energy bills.

Certified technicians will locate these air leaks through the performance of an energy audit and then seal the leaks with a combination of caulk, foam, and other sealants. Typically, a home’s attic and basement will have the most air leaks.

Why is Air Sealing Important?

Leaks in the interior walls, duct system, and other areas of your home will allow conditioned air to escape – meaning that you are wasting energy and money trying to keep the temperature in your home at a comfortable level. Additionally, air leakage can cause the R-value and thermal performance of insulation to diminish, as most insulation products were not created to impede moving air.

Our heating and cooling system was not operating properly and we were afraid of the cost and quality we’d receive from the wrong contractor. BUT…Every time we called, someone from Minnick’s answered the phone and provided me with an answer. We were especially pleased with the reasonable costs, knowledgeable and on time (every day!) and the Customer Service!
