Your home is a heating and cooling system, and there are many factors that contribute to or detract from its overall performance and comfort. While you may have the most efficient furnace, heat pump, or air conditioner, it won’t do its job well without proper insulation, air sealing, ductwork, and maintenance.

A healthy and comfortable home starts with insulation and air sealing.


Air Sealing


Our trained, certified, and friendly technicians first audit the overall performance of your home to determine what will reap the highest benefits for you. From there, we determine which type of insulation you have, how well it’s working to seal your home, and then recommend the best solution for your comfort. We offer both spray foam and cellulose insulation to provide you with flexibility and comfort.


Save money on utility bills with air sealing

Air sealing is one of the most important – yet little known – building performance improvements around. Sealing hidden air leaks throughout your home improves comfort, lowers energy bills, and creates a more environmentally friendly home.

Air leaks occur when the air outside your home gets inside through cracks and other openings.

While a certain amount of airflow is necessary for health, too many air leaks in your home can be like leaving the window open all year round. With drafts, cold spots or leaks in the interior walls or duct system come wasted heat and air conditioning, discomfort, and increased utility bills.

Plus, your insulation won’t do its job as well as expected if there are air leaks.

Minnick’s fixes air leaks with a combination of caulk, foam, and other sealants, often with a primary focus on your home’s attic and basement – where air leaks occur most often.

Proper insulation plays an important role in both the summer and winter, helping to bring down your utility bills while increasing your comfort by keeping your home warmer in the winter and cooler in the summer. Insulation throughout your home from the roof to the foundation helps achieve maximum comfort.

Spray foam insulation fills in all the gaps and spaces because it expands when sprayed. It doesn’t disintegrate like some cellulose insulation because it gets hard when sprayed. Plus, spray foam resists moisture more effectively.

Cellulose insulation is made of recycled newspaper. It’s commonly found in attics, new construction, walls, and retrofit situations.

Insulation plays an important role in making sure your whole home is as energy efficient as possible.

Energy audit spots air leaks

A Home Energy Audit provides you with a comprehensive view of how your home functions to achieve comfort and efficiency, identifying problem spots and recommendations on how to address them to achieve your home comfort goals.

The audit looks at every room and identifies areas of energy loss. Minnick’s pays special attention to the basement, crawlspace, attic, and combustion appliances.

Using a blower door to test for leaks, Minnick’s certified energy auditors test your home for air leaks and cracks. We also conduct a visual inspection of ductwork, and a load calculation of whether or not your equipment is delivering enough or too much air to the rooms in your home.

While insulation and air sealing solve some of the problems we find in energy audits, Minnick’s also make suggestions for other ways you can achieve greater comfort and efficiency in your home.
