Five Reasons An Oversized Furnace Is A Bad Idea

If you install an oversized HVAC system in your home, it can lead to big problems. When you install an HVAC system into your home, you want it to be the right system for your home.

Otherwise, you may end up having to replace a furnace years before you should.

Bigger isn’t always better, and we are going to tell you why that’s the case when it comes to your home heating system!

Five Reasons You Shouldn’t Have An Oversized Furnace In Your Home

  1. Your Home Won’t Stay Comfortable
  2. Your Furnace Could Break Down
  3. Your Energy Bills Will Be High
  4. You Will Overpay For Your System
  5. Your System Won’t Have A Full Lifespan

Your Home Won’t Stay Comfortable

If your furnace is too big, it can cause discomfort in your home. You may be thinking that it’ll do a great job, because it’s more powerful than it needs to be to heat your home, but it actually causes your home to heat improperly.

A larger furnace will generate more heat, and pump it out quickly. The problem is that this larger output can cause your thermostat to think the whole home is heated,

But, it really only produces a large enough portion of heat up a certain space, and the other parts of the house may stay cool. The thermostat then shuts your furnace off before it’s heated the whole home.

This is called “Short Cycling.” Short cycling will keep your furnace from running smoothly, and heating the entire home properly.

Your Furnace Could Break Down

Short cycling means your furnace is constantly turning off and on far more often than it should. This can cause breakdowns and unnecessary wear and tear on your furnace.

Just like city miles are harder on a car than highway miles, this constant stop and start could lead you into needing more repairs than you should, and an unreliable heating system.

Your Energy Bills Will Be Higher

A larger system that produces larger amounts of heat will also require larger amounts of energy to run. If your system is short cycling, it’s also going use more energy than if you had a proper system that maintained the right temperature.

This increase in energy use is going to lead to an increase in your energy bills as well.

You Will Overpay For Your System

If you are purchasing a furnace that is too big for your home, it stands to reason that you are buying a furnace that is more expensive than the one you need.

As furnaces get bigger, they also go up in price. The truth is, you are overpaying for your heating system, and should get the smaller one that is the right size for your home.

Your System Won’t Have A Full Lifespan

Your furnace should last for 10+ years. If you purchase the wrong system for your home, it has a chance of dying early.

If your system is always short cycling, and working harder than it has to, it’s not going to last as long as it should.

Even if it’s a big, expensive system, it’s still subject to taking a beating if it’s not used properly.

Focus On High Efficiency Furnaces

Instead of worrying about the size of your furnace, focus on efficiency. If you are looking to buy a bigger furnace than you need, what you really are looking for is the most efficient furnace.

Higher efficiency means better performance, better comfort, and lower energy use.

The best advice we can give you is to do your research online (which clearly you are doing now), but also speak to an expert.

Have an HVAC contractor come into your home and make a recommendation. They will be able to help you choose the right sized furnace, with the best efficiency.
