A Guide to Problems With an HVAC System's Size

September 28, 2021

When you need to install a new HVAC system, the right size depends on your home's square footage and layout. Choosing the perfect match for your home is essential because it helps you prevent maintenance issues and increased utility costs. If you're wondering why contractors inspect the home before recommending a replacement, here is an introduction to the problems that can arise with an improperly sized system.


Why Are Oversized HVAC Systems Problematic?


When your HVAC system is too large for the home, it will start to short cycle, which is when the air conditioner or furnace shuts down early because it reaches the desired temperature too quickly. This means your unit will stay in the initial stage of cooling down or warming up. As a result, additional moisture or humidity can linger in the air. High humidity can negatively impact your overall comfort when at home, as it makes the air feel warmer, even at lower temperatures. Plus, the process of constantly turning on and off results in unnecessary wear and tear on mechanical components. Short cycling also produces more noise because the system activates frequently, which can be disruptive to your activities.


What Happens When the System Is too Small?


Heating and cooling systems that are too small will also lead to general discomfort and issues as they cannot keep up with demand. You may notice that some areas of the home are much warmer or colder than the rest of the property, which occurs because the system isn't circulating enough air.


During periods of extreme weather, the HVAC system will run constantly throughout the day to try and correct the interior temperature, leading to high energy bills without achieving the desired climate. This may require you to invest in supplementary fans and space heaters to maintain a comfortable temperature in the home. In some situations, heavy usage of small heating and cooling systems can prompt overheating or frozen evaporator coils, causing the system to shut down. This leaves you without temperature control when you need it most.
