Manual J: The Standard When It Comes To Installing Your Air ConditionerAs a homeowner in the Indianapolis area, you’re well aware of how hot and humid our Indiana summers can become. Because of this, you’ll want to make sure that your new air conditioner installation will properly cool and remove moisture from your home. When your HVAC contractor sizes your air conditioner properly with Manual J load calculations, you can rest assured that you’re getting the most bang for your buck.

What is Manual J?

This sizing tool was developed by HVAC experts in order to properly determine the sensible and latent cooling loads of homes. These load calculations will help your contractor precisely select the right-sized cooling equipment for your home’s size and characteristics.

What do Manual J load calculations consist of?

Your HVAC contractor will consider numerous factors as they calculate your home’s cooling load. First, they’ll consider our Indiana climate, as well as the shape, size and orientation of your house. The type of insulation and windows in your home are also key to determining the cooling load. Also of importance is the number of people within the household, their ages and comfort preferences. Your contractor will look at how well your home is sealed and whether ductwork modifications will be required.

How can Manual J benefit me?

When your air conditioner is properly sized, you’ll experience a higher level of comfort and a lower energy bill. A system that’s too large will not run long enough to dehumidify your home properly, which will leave you feeling clammy, and can also create conditions that are ideal for mold and mildew growth. An oversized air conditioner will use too much energy while not providing even cooling in your home. Meanwhile, an A/C that’s too small will struggle to satisfy your temperature demands.

The sizing of your cooling equipment is more than just guesswork. Don’t settle for anything less than a contractor prepared to accurately calculate your home’s needs with Manual J.
