Why Our Installation Process is Different
Most companies simply "swap out" your old unit for a new one. At Grandmark, we treat every AC installation as a custom engineering project to ensure your system actually delivers on its efficiency promises.
Custom Load Calculations
We analyze your home’s square footage, window orientation, and insulation levels to ensure your new system is sized perfectly—preventing short-cycling and uneven cooling.
Thermal Integrity Testing
We use thermal diagnostics to inspect your existing ductwork before the AC installation. This ensures your new high-efficiency unit isn't held back by hidden air leaks or restricted flow.
