HVAC Plan Symbols

What are HVAC Plans?

HVAC (heating, ventilation, and air conditioning) plans refer to the drawings made by specialized engineers that include all the details needed to create, set up, and maintain the heating and cooling system in a building.

The HVAC plans are quite important and are developed once the building's floor plans have been completed. The engineers use their expertise to develop the most effective and efficient system – a system that requires minimal wiring and cost but still caters to the needs of the building's inhabitants.

But how do the engineers create an HVAC plan? Just like coding, HVAC plans include special symbols to indicate the equipment for heating, ventilation, and air conditioning. What are these symbols, and how are they categorized? Let’s have a look.

What are HVAC Plans used for?

Since HVAC plans would provide the overall floor plan related to heating, cooling, and ventilation, they can be used in different ways.

  • It acts as a first step in setting the air conditioning or the thermal system in any building
  • After coming up with an HVAC plan, you can tell your clients about the overall budgeting and deadlines.
  • An HVAC plan would help you decide the cost of other tools and equipment that should be installed in the structure.
  • Apart from being a vital tool for construction and engineering, it can also help in maintaining and planning the system.

HVAC Plan Symbols

HVAC drawings consist of various symbols, each representing a component such as pumps, fans, silencers, air filters, regulators heaters, and surface air coolers. The symbols used in the drawings of HVAC plans in almost every building – whether it be a factory, an office building, or a residential one – can be categorized into four groups.

  1. HVAC Controls
  2. HVAC Equipment
  3. HVAC Ductwork
  4. HVAC Controls Equipment

For your better understanding, we have added illustrations of the symbols from each of these categories.

How to Make a HVAC Plan Quickly?

The best way to draw HVAC plans is by using user-friendly software. Our recommendation is EdrawMax because it provides you with all the HVAC symbols, pre-drawn templates, and video tutorials for each step. Moreover, if you’re just entering the drawing and designing niche of HVAC systems, using EdrawMax may be the perfect choice because of its simple, straightforward user-interface.

The software has a free version that offers limited features, but if you want to access premium features and high-end templates, we recommend an upgrade to the premium version. Not only will it save you hours in designing HVAC systems. But it will unlock some additional HVAC symbols that you may need.

One of EdrawMax ’s best features is that you can access it through a browser or by downloading the application. If you’re short on space on your PC, this might just be the option you are looking for.

Steps to Create an HVAC Plan Using EdrawMax

Making HVAC plans using EdrawMax is a very straightforward process. Here’s a step-by-step tutorial to guide you through it:
