Residential Heat Gain
First Step to a Successful Air Conditioning System Design

 We have come a long way since the advent of the fan. Mechanical cooling systems, when properly designed and installed, provides us with a comfortable atmosphere throughout our homes and businesses. This mechanically controlled atmosphere allows us to be more comfortable and more productive.

Do you know what the principle job is of any residential central air conditioning system? Is it to "cool down" a residential structure? The answer, for the most part, is no. The primary job of any such system is typically to gently, and evenly remove heat energy and water vapor that is gained by a structure.

For years, we have had the technology that enables us to accurately determine how and where heat energy is gained. Unfortunately, there is a substantial amount of math and science involved with this technology, and many air conditioning mechanics (who call themselves "contractors") never made the commitment to thoroughly understand the science of heat gain.

A cooling system will not perform correctly if it is not properly sized. It often ends up that one room is too warm while another room feels chilly. A system that is too large will lower the temperature of a structure (or zone) too quickly, undershooting the desired temperature set-point. In addition to the comfort issue, the structure will have humidity problems because the equipment isn't running long enough to remove excessive humidity. An oversized system will also waist energy.

Did you know that HVAC businesses are liable for the systems they design. A home owner, or a general contractor is relying on you to be an expert in the HVAC field. If you fail to properly size a cooling system, you could be (and in the opinion of the Furnaceman - "should be") subject to a law suite.

If you are using "rules of thumb", or some cardboard calculator, or relying on a canned software package to determine heat gain, you need to take our course. Students who successfully complete this course will understand the various ways heat energy is gained by a structure. They will be able to calculate "on the fly" the various gains that affect a structure. A person knowing this material will be able to identify improperly sized systems, and that person be in a position to capitalize on the lack of knowledge of others.

This is not an easy course, and it requires a solid understanding of math, including basic algebra. For those who successfully complete this course - you will be ahead of most "so called" air conditioning contractors.

The residential heat gain course runs for a minimum of 24 hours, and can be scheduled evenings, or days. Class size ranges from 10 to 16 students. Students must bring a calculator to class.
