This tech tip was a COMMENT on a Facebook question about how ductless systems achieve some of their high-efficiency numbers at the expense of dehumidification. This was the question: Bryan Orr mentioned that multi-stage mini splits often do very little latent cooling (dehumidification) because on low speed the manufacturers all “let the evaporator float, which […]

This article was written by Senior Boiler Tech Justin Skinner. Thanks, Justin. Oil burner nozzles are present in most forced combustion air burners. They are used with an oil pump to atomize fuel oil and allow it to burn. Atomizing is raising the pressure of the fuel and forcing it through the nozzle. Essentially, the […]

In HVAC and electrical school, one of the first things you learn about electricity is Ohm's law: Volts (V) = Amps (I) x Ohms (R) Pretty simple, right? Watt's law is just as easy: Watts (P) = Volts (E) x Amps (I) With this newfound knowledge, the student walks confidently into the real world with […]
