I've been told a Manual J is a waste of time and money. Is that true?
Many original HVAC systems are not correctly sized for their respective buildings. Traditionally, the practice of builders using the “lowest bid contractor” to install the HVAC system in new homes resulted in numerous corners being cut. The ONLY way to know if an AC system is sized correctly is to calculate the existing heating and cooling loads using a Manual J calculation.
How big of an air conditioner do I need for my home?
The ONLY way to size an air conditioner for your home is for a heat load calculation to be performed. The capacity needed is based upon how quickly your home gains or loses heat, not simply by square footage alone. Manual J is an industry-approved method that Mister Aire of Jacksonville uses to ensure the proper system is selected for you.
Will having a Manual J performed save me money?
Whether you are a homeowner or a contractor, the MOST important reason to have a Manual J calculation for your home is SAVING YOU MONEY. Oversized HVAC systems require more money for installation. The oversized equipment also costs more than properly sized equipment. More money is needed for oversized refrigerant lines, vents, and larger duct and more money is also needed in labor to install the additional equipment. A Manual J performed by a credentialed licensed contractor, such as ourselves, can save money, promote prolonged equipment life, improve comfort and conserve energy.
