HVACR DepartmentThe HVACR (Heating, Ventilation, Air Conditioning, Refrigeration) Department invites you to further your education by choosing from a wide selection of night courses. Courses are offered at convenient times and taught by instructors that appreciate the difficulties of working, raising a family, and taking classes.
Principles of Air Conditioning & Refrigeration
ACR 1104 (4 credit hours)
Are gauges all your technicians know? There is a lot more to diagnosing a problem than pressures. “Principles” helps students understand the “whole” process. This knowledge translates into thorough diagnosing and fewer call backs.
Residential HVAC: ACR 2104 (4 credit hours)
This is the course where theory begins to take body in “hands on.” Students are required to understand and be capable of charging an air conditioner and heat pump. Emphasis is also placed on the Psychometric chart and understanding the technicians role in controlling latent heat.
Basic Electrical Circuits
ELT 1304 (4 credit hours)
Special emphasis is placed on understanding the basics of diagnosing air conditioning electrical problems. Students learn to read schematics and apply that knowledge for troubleshooting and installation purposes.
Introduction to Sheetmetal
ACR 1302 (2 credit hours)
Introduction to Sheet Metal provides students with basic knowledge and skill with tools and equipment found in a residential metal shop. Even if a contractor uses an outside shop for most of their metal work, these skills will be of importance. The goal is to make sure that the successful student can keep the job going by building a plenum or simple transition when needed.
Manual J - Residential Load Calculation
ACR 1503 (3 credit hours)
Arkansas code now requires that a Manual J be completed on each house. This course focuses on understanding heat loss and gain, sensible and latent load, and how residential construction relates to the selection of properly sized HVAC equipment. A successful student will be able to perform a Manual J load both manually and with an ACCA approved Wrightsoft computer program
Business Management for HVACR Contractors
ACR 2203 (3 credit hours)
Business Management goes to the heart of the HVACR business—costs, profit, and employee retention. Upon completion, students will be familiar with a profit / loss statement, a balance sheet, and know how to price and manage for profit and retirement.
Codes & Ordianaces: ACR 1402 (2 credit hours)
The Arkansas Mechanical code is the source book for the Codes & Ordinances class. Special emphasis will be given to health & safety issues; i.e., flue venting, combustion air, and wiring. Further consideration will be given to the role of contractors in providing customer service through quality, code compliant installation.
