New HVAC Systems By Griffin Mechanical, LLC We have installed new heating and air conditioning systems in Middle Tennessee since 2001. Whether you live in Dickson, Nashville, Brentwood, or Franklin, we can install a new system that’s right for your home. New HVAC System Installation Griffin Mechanical, LLC installs all brands and models of heating and cooling equipment. Every year we research industry standards to determine what units are the best for the money. We share that research with you in order for you to make the best decision in your home. We want you to be fully satisfied with your decision and our installation, and we belive that the first step on that path is with information. We also use Manual J load calculations to determine the right size HVAC unit for your home. It is imperative that your new system is the proper size. If the unit is too small, it will run far longer than it should trying to heat or cool your home. This leads to higher energy bills and a unit that will wear itself out very quickly. If the unit is too big, it will heat or cool your home too quickly, causing the unit to power on and off too often. This is called power cycling, and it can reduce the life of the unit dramatically. Our Knowledge And Experience Are Second To None Griffin Mechanical employs a dedicated department of HVAC service technicians. Every year our technicians undergo hours of training, evaluation, and certification. They are skilled on every brand and model HVAC unit, and have the experience to properly install them in your home.
