Common Mistakes To Avoid During Furnace Unit Installation

by Marvin Carroll

Furnace unit installation is a crucial process that needs to be done with utmost care and attention to detail. One mistake can lead to costly repairs and potentially dangerous situations. Unfortunately, many homeowners try to install their furnace units themselves or hire unqualified professionals, leading to errors and problems down the line. This article will provide an overview of the common mistakes to avoid during furnace unit installation to help ensure a safe and effective installation process. From the obvious to the obtuse, here are three of the most common mistakes you can make during a furnace unit installation at your home.

Attempting To Install It Yourself

The biggest mistake homeowners make during furnace unit installation is attempting to do it themselves or hiring an unqualified professional. HVAC systems are complex, and a poorly installed unit can cause a host of problems, from inefficient performance to potential safety hazards. Always hire a licensed and experienced HVAC contractor to ensure a safe and effective installation. There are many of them around, and it doesn't cost that much to have it done well, especially when you consider just how long these furnace units last. If you are thinking of installing it yourself, or getting your friend who is unqualified to do it but thinks they can, then you should seriously consider how dangerous this could be and then call for an expert.

Incorrectly Sizing The Unit

One of the most common mistakes during furnace unit installation is not sizing the unit correctly. If the unit is too small, it won't be able to keep your home warm, and if it's too large, it will waste energy and money. To ensure you get the right size furnace unit, have a professional HVAC contractor perform a heat load calculation to determine the appropriate size for your home. This is a simple calculation but one that non-experts struggle to get right, which is another reason why the presence of professional contractors is so necessary. 

Poor Placement Of The Unit

Another common mistake is placing the furnace unit in an inappropriate location. It should be installed in a well-ventilated area that's easily accessible for maintenance and repair. Avoid placing it in a cramped or enclosed space or near flammable materials, as this can pose a fire hazard. This is something that many homeowners accidentally get wrong because they want to put the unit in a place that looks good, rather than one that is the most economically viable. Do not try to overrule your HVAC contractor, listen to where they suggest putting it and follow their advice.
