WHAT IS A MANUAL J?
Whole House Load Calculation
A Manual J is complete residential calculation used to determine how much heating/cooling a home needs to stay cool and dry during the summer or warm during the winter.
This load calculation process was developed by engineers in the heating and air conditioning industry and has been used for decades to accurately size heating and air-conditioning equipment.
Once you have this complete load calculation, you will have the certainty of selecting a properly sized system to satisfy the load of your property. Here is a step-by-step guide on what a Manual J calculation entitles (Career development section by indeed.com)
Why should I get a Manual J on my property?
A Manual J will provide for you three important pieces of information about the heating and cooling load of your residence:
- Heating Load:
How much heat your property will require on the almost-coldest day of the year, in the middle of the night (when the sun is not present). With this number or load you will be able to select the right piece of heating equipment. - Sensible Cooling Load:
The amount of sensible heat (what you can usually measure with a house thermometer) that your system should be able to remove on the almost-warmest day of the year, during the daytime (when the sun is at its strongest point). In conjunction with the “Latent Cooling Load”, this load will help you to select the right cooling equipment. - Latent Cooling Load:
How much moisture your system should be able to remove under “worst-case” conditions. Worst-case for latent loads is typically when it’s hot and wet outside (i.e.daytime in the summer).
With these three loads you will be able to select the exact equipment to fit the loads (heat losses or gains) of your property. No oversize risk, no money electricity overpay, EVER!
Why Should I do Room by Room Manual J Service?
When buying a Manual J Service, selecting a Whole House Summary or a Room by Room analysis is determined by whether you are going to size the duct system or just the equipment needed.
A Whole House Summary looks at the structure as a whole and gives you the total for whole structure. A Room by Room report looks at each individual room and gives you an individual room requirement. This is only necessary if you are sizing the duct system.
- Whole House Summary Report: Provides a Manual J Calculation for the entire house. It will give you a total heating and cooling BTUH requirement for the entire envelope so you may choose the properly sized equipment .
