New Year, New Knowledge: Mastering HVAC Acronyms

Year 2020 Start, Two Thousand and Twenty Concept.

It’s a new year, and we here at Lindstrom Air Conditioning & Plumbing want to help you start 2020 right! One way we can help is with some new knowledge in HVAC acronyms. Does it ever feel like your technician is speaking a foreign language? We do our best to explain how we are servicing your HVAC and plumbing systems, but here are a few common acronyms to help you better understand what your technician is referring to on our next visit!


You probably know this one, but why not start with the basics? A/C stands for air conditioner, which is your system or mechanism that extracts heat from an area and humidifies the air. Lindstrom also offers heat pumps or heat strips that work in conjunction with your A/C to provide comfort on those chilly January nights.


AHU stands for the air handling unit, which can also be abbreviated AH. This unit typically consists of your cooling (and heating) elements, as well as a blower, filter chamber, humidifier, ampers, and other equipment that comes in direct contact with the airflow. As implied by the name, the AHU does not include ductwork throughout your home.


The EER stands for energy efficiency ratio. This is a calculation of the output cooling energy compared to the input electrical energy. The EER is normally calculated with a 95 °F external temperature, 80 °F internal temperature and 50% relative humidity. You may also see the acronym SEER in this situation. This stands for seasonal energy efficiency ratio and is used to look at a specific season or time frame. Your Lindstrom technician can use this calculation during routine maintenance checks to determine how your system is running and what can be done to improve its efficiency.


PRV stands for pressure regulator valve or pressure relief valve. This valve is designed to regulate the incoming water or steam pressure to a safer level for use. Lindstrom can conduct a PRV inspection to ensure that your valve is producing the optimal amount of pressure. Too much or too little can be both inefficient and dangerous.


PVF is shorthand for pipe, valves, and fittings. This is sort of a catchall term for the various plumbing equipment in your system.


Volatile organic compounds (VOCs) are compounds that can easily become vapors or gases. These chemical odors (plus smoke, musty air and more) can be reduced or even eliminated with air purifiers and UV lights provided by Lindstrom.

Hopefully, these abbreviations help on your next visit from Lindstrom! Call us today at (800) 813-1824 to schedule your 2020 appointment!
