HVAC FAQ: Is a Bigger System Better?

family-with-dogThe quick answer to the question posed in the title of this post? No, not at all. If you are serious about getting the very best performance possible from your HVAC systems, then you need to do more than just invest in great systems from trusted manufacturers. You need to ensure that those systems are also appropriately sized for your home. While it may not seem like it, an oversized air conditioning or heating system is actually no better than one that is too small for your home.

We understand that this may sound counterintuitive to some of you out there, so we’ll use today’s post to help you better understand how it is that an oversized HVAC system can negatively affect your comfort, your budget, and the system itself. Remember, once you have an oversized air conditioner or heater in place, there is no way to fix that problem without replacing the entire system. That is why you should work with the Burlington, WA HVAC pros on our staff — we do the job right the first time, every time!

When Bigger Isn’t Better

Whether in terms of the engine in a work truck or the balance of a bank account, we tend to equate bigger with better. It is not always the correct association, though. These are some of the problems that you’ll encounter when you invest in a system that is bigger than you need for your home.

  • Wasted capital. Right out of the gate, you are going to be wasting money when you allow a company to install an HVAC system that is bigger than you really need to keep your home comfortable. Why pay for a heating or cooling capacity that you will never truly require? Our technicians won’t mislead you, and we won’t let your HVAC system get off to such a bad start.
  • Excessive wear and tear. Did you know that an oversized HVAC system can heat or cool a home too quickly? That may not sound like a problem to you at all. Think about all of the wear and tear that the system incurs as it starts up, runs briefly, cycles down, and repeats the process, though. It’s called short cycling, and it causes big problems.
  • Increased energy costs. Not only does short cycling, as described above, increase the risk of operational problems with an HVAC system, but it also increases energy costs. It requires more energy to start up a system up over and over than it does to simply keep that system running consistently, which leaves you with increased energy costs even as system performance falls off.

When you invest in a new HVAC system, you need to know what the heating and cooling load in your home is. This is the type of calculation that only trained professionals can make. It is not as simple as just looking up the square footage of your house. We’ll make sure that we know just how powerful a system you need before we install a new one in your home.
