Air Conditioning can be complicated, but one way to get acquainted with what your air conditioner repair man might say is by being familiarized with key terms. Think of this as a homeowners vocabulary list. You can even print this out to use as reference when your next air conditioner repair team pays you a visit!

Sensible Cooling Load P: heat in the home based on conduction, solar radiation, appliances, people, pets and infiltration. A light switch that is left on, and the heat emitted from that light bulb is an example of sensible load.

Latent Cooling Load P: Basically like the opposite of sensible cooling load, the latent cooling load is the amount of moisture added to your home's interior by plants, people, cooking, and any other moisture source. Even the steam and liquid in your bathroom after taking a shower can be latent cooling.

Energy Efficiency Ratio: the EER is the efficiency of your air conditioner. This number changes with the inside and outside conditions and it drops as the temperature between indoors and outdoors increases.

Seasonal Energy Efficiency Ratio is a set of tests used to rate air conditioners. Tests consist of air conditioner performance in different conditions‚ such as humidity, dry air, and dry indoor conditions. It does not always pertain to every climate.

Manual J, Manual S, and Manual D: J is widely accepted as a means to calculate sensible and latent cooling loads. S is used to ensure that sensible capacity and latent capacity will be able to meet the cooling load through the right equipment, and D is related to duct system engineering.
