Whole Home Action Plan

While our skilled, trained, and friendly HVAC technicians are able to fix common heating and cooling issues, we really shine when it comes to getting you more comfortable in your entire home. Is there a room or a floor of your home that doesn’t feel right? Does your house smell musty? Even the most energy efficient equipment won’t work optimally if your whole home heating and cooling system is not addressed.

It’s important to look at your entire home as a heating and cooling system. A healthy home means healthy living.

Minnick’s Whole Home Action Plan looks at your insulation, ductwork, ventilation, and plumbing to make sure they are working properly and not contributing to greater discomfort or higher utility bills in your home.
