An HVAC is a heating, ventilation, and air conditioning system. It helps make your rooms or home comfortable by cooling, heating, cleaning, or drying the air. There are different types of HVAC systems that you can consider for a home or business. Having a malfunctioning HVAC can be frustrating. However, with an HVAC system diagram, it can be easier for specialists to quickly find all the inputs of the system thus quickly resolving issues. Continue reading to understand everything about an HVAC system diagram better.
What Is a HVAC Diagram?
An HVAC diagram helps you understand all the inputs of your heating and cooling sytstems. The diagram better illustrates how your HVAC works around the house. It will typically include the vents, the intakes, the air purifying systems and any other in-line appliances. With a detailed HVAC diagram, specialists can easily navigate the best location to enter a duct for precise maintenance and repairs. For example, if there is an issue with the ductwork in the house, the specialist can use the diagram to figure out how its routed around the house. Not only does this save time, it makes it easier to resolve the issue.
Where Can You Find the HVAC Diagram?
You may be able to find a copy of your HVAC diagram in your building permits. If you did not build your home, this may still be available in county records. The newer your system is, the more likely you are to find this information filed with an official permit.
Types of HVAC System Diagrams
HVAC diagrams fall into two categories, installation, line, and ladder. Installation diagrams help an HVAC contractor connect and install your unit. The diagram is essential for the first time, and the contractor doesn’t need to use them when conducting repairs.
Line diagrams are difficult to read since the unit’s parts are drawn more realistically. All components in the diagram are named, but the technician must understand how every part works.
Benefits of Having an HVAC Diagram
There are many benefits to knowing how the air is routed around your house. Here is a look at some of the most common ones.
If certain vents are not emitting enough air, a diagram allows your technician to work backward to find a leak or clog. Starting at that vent, the technician can check if the airflow in all of the vents after this one are also slow. They can check if the vent before this one in the duct line is working correctly as well. This can help them pinpoint the location of the problem before they break out expensive monitoring equipment and save you time and labor.
If you are planning to renovate and add a room to your home, a diagram will show how easy it would be to connect that room to the current duct system. If it’s easy, the diagram also gives you an idea if your furnace, heat pump or AC is already sized to encompass the new room and recommendations will be about whether to maintain or upgrade your main heating and cooling appliances. If it’s too complicated, your technician is likely to recommend something like a ductless mini-split instead.
Considering Air Quality or Humidity Control
A diagram helps your HVAC technician decide whether an in-line air purifier makes sense or if you would want a separate system. This will be based on whether there is adequate room and a decent power supply to attach it to your existing system. If you are considering an in-line humidifier or dehumidifier, a diagram will help your technician to choose a location with an existing water supply or reasonable drain route.
Adding Zones to Your Existing System
Zoned systems are a great way to keep from heating or cooling unused rooms in your home. An HVAC diagram will show the best locations to add zoning and give you an idea of natural zones based on the routing of your ductwork.
