EER in the Field - Short #231

HVAC School - For Techs, By Techs ·

2025/02/18

In this short podcast episode, Bryan talks about EER (Energy Efficiency Ratio) and SEER (Seasonal Energy Efficiency Ratio) and how to calculate EER in the field. EER and SEER are ratings that we often see on equipment (as are SEER2 and EER2) based on a ratio of an output to an input. Whereas coefficient of performance (COP) is a direct ratio of watts out to watts in, EER and SEER account for BTUs and watts. EER and SEER indicate the cooling capacity (in BTUs) we get from the watts we put in. The

In this short podcast episode, Bryan talks about the standing pilot gas systems and the ignition strategy in gas-fired appliances. Standing pilots are very simple devices that are common in fuel logs, water heaters, and some pool heaters. These devices have a thermocouple or thermopile; in a thermocouple, two dissimilar metals are connected at one end, and there is an electron flow between the metals when one is heated up. A thermopile is a collection of thermocouples in series or parallel to

History of Gas Furnaces - Redux

HVAC School - For Techs, By Techs ·

2025/01/23

Jim takes us all the way through the history of furnaces, from the Stone Age when he was a child to modern modulating condensing types. The goal of a furnace is to move heat, so a furnace uses heat exchangers to facilitate heat transfer. Furnaces have primary and secondary air. The primary air goes through the burner, and the secondary air goes around the flame and is pulled in around the heat exchanger inlet. So, the flame's heat creates a draft that pulls air in. Natural gas and oil (LP/propane)

Heat Exchangers and Temperature Rise - Short #227

HVAC School - For Techs, By Techs ·

2025/01/21

In this short podcast episode, Bryan talks about heat exchangers and temperature rise in gas furnaces, especially 80% open-combustion gas furnaces. Temperature rise is the difference between the return air temperature and supply air temperature; in cooling, we usually refer to this difference as a delta T or temperature split. The manufacturer sets a target range on the data plate; high-efficiency furnaces tend to have lower temperature rise targets than mid-efficiency or older furnaces. We want to

Q&A - Double Flares - Short #225

HVAC School - For Techs, By Techs ·

2025/01/07

In this short podcast episode, Bryan answers a listener-submitted question about double flares and their application in the HVAC/R industry. Flare connections are common in certain types of equipment, and they connect the copper to the appliance. As a result, when we make a flare, our goal is to make it leak-free. A regular flare requires you to cut the copper, clean it, put the flare nut on, and make the flare with a flaring block (or a flaring tool). You can also put a little bit of oil on the

Q&A on Superheat - Short #223

HVAC School - For Techs, By Techs ·

2024/12/24

In this short Q&A podcast episode, Bryan answers a listener-submitted question about superheat, including what it is and how we measure it. Superheat is the number of degrees a refrigerant is above its saturation point. The saturation point is where you will have a liquid-vapor mix, so superheat only exists when a substance is a vapor. Saturated refrigerant should only exist in the evaporator and condenser, during which it is being boiled or condensed. We usually measure superheat at the evaporator
