There’s an idea for some that bigger is always better. This concept can be applied to many different aspects of your life, but sometimes it can cause some issue. Some people think that it’s beneficial for them to invest in an oversized HVAC system. However, you should purchase one that’s right for the size of your home. Here are some of the top reasons why you should avoid an oversized furnace and AC unit.

You Could Sacrifice Efficiency

One of the reasons people think they should opt for an oversized HVAC unit is that they think it’s going to be more efficient and save money on energy bills since it’s meant for a larger sized space. The truth is that by getting an oversized unit, you could be sacrificing efficiency. In this instance, bigger doesn’t necessarily mean better. You could be wasting more energy by having a more substantial unit without getting anything beneficial out of it.

Poor Air Quality

A furnace or AC unit that’s too big for your space can contribute to poor air quality in your home. For instance, with a bigger system than necessary, you can have higher humidity than if you had a unit that was the correct size for your home. It can also contribute more dust to your home. These issues can lead to problems like mold in your home.

Make sure your HVAC is cleaned properly and regularly by using a service such as Portland air duct cleaning service to make sure your unit is in the best condition it can be.

Air Duct Issues

The air ducts in your home were built originally for the right size HVAC unit in your home. Installing a more substantial unit can put a strain on your air ducts and the unit itself. It can result in high static pressure, which means that your system can’t breathe because of the lack of duct size. This can cause things like your indoor fan motors to stop working correctly, leading to more maintenance.

Uneven Temperatures

Another reason people think to choose an oversized HVAC unit is that they’ll have more consistent temperatures. They have this misconception that quicker airflow into the room will make it stable, but that’s not the case. You may find that a larger unit results in uneven temperatures throughout your home.

Damage the Unit Over Time

An oversized unit could have a shorter life cycle when being used in a smaller space than it’s meant to be used in. For instance, an oversized AC unit will think that the job is done earlier than it should, and this will turn off the compressor early. Then, it turns back on shortly after that to cool the space, and then, it mistakenly thinks it’s done turning off too soon again.

This cycle continues over and over. It’s a waste of energy, hurts the parts inside the unit, and may require more frequent servicing than necessary.

You want an HVAC system that will help make you feel at home. The best choice is one that will fit your needs based on the size of your home. An HVAC technician is an excellent source for determining what size unit makes the most sense for your home’s layout. They’ll help you to make an educated decision on size rather than just going for the largest unit you can.
