HVAC Installation Question: How do I know I’m getting the right system for my home?

For your new system to function properly, it needs to be sized appropriately for your home. Your contractor will perform a calculation called Manual J, also called a load calculation. This considers various factors about your home that contribute to heat loss, heat gain, and efficiency. Measurements are taken, construction and features of the home are considered, which help your contractor determine the capacity needed for a new system, and other needs to facilitate the new system install, such as ductwork installation or sealing to improve energy efficiency.

If a contractor offers a quote over the phone or does not visit your house, you cannot know that the system is the right size for your home. Before choosing a contractor to perform your installation, ask if a load calculation was performed and why the contractor has recommended the specific model and capacity of heating or cooling equipment for your home.
