Are Bigger Units Better?

Two HVAC units. One is larger than the other.

If you've ever had to replace your HVAC system, you know there's a lot of different sizes. It's easy to look at the larger, more expensive units and think they'll give you the best bang for your buck. After all, in many areas of life, bigger often does mean better. But when it comes to keeping your home comfortable, that giant HVAC unit may cause you a lot of problems. Let’s break down why going big on your HVAC might actually lead to some big headaches instead.

First up, let’s talk about short cycling. Imagine you’ve just bought a giant HVAC unit. It roars to life, cools or heats your home in a flash, and then, just as quickly, it shuts down. Rinse and repeat. This might sound efficient, but it’s actually quite the opposite. This start-stop cycle puts a ton of stress on your unit, causing it to wear out much faster than it should. Plus, it means your home’s temperature is constantly up and down, making some rooms feel like a sauna while others are more like a fridge.

Then there's the humidity problem. Bigger units cool the air so quickly that they don't stay on long enough to pull moisture out of the air. This will leave your home hot and humid, especially with the types of summers we have in the Upstate. All of the extra humidity isn't just uncomfortable, it can also lead to mold that is dangerous to breathe in all the time.

Speaking of unwelcome surprises, let’s talk about the energy bill. You’d think that a bigger unit would be more efficient, but it’s actually quite the energy hog. Since it’s always turning on and off, it uses a ton of power, and that’s going to show up on your energy bill.

Last, but definitely not least, we can't forget the upfront cost. Bigger units come with bigger up front price tags. The spending doesn’t stop there either. With all the wear and tear from short cycling, plus the higher energy costs, and the potential for mold, you could be spending way more than you bargained for in the long run. When your oversized HVAC unit decides to call it quits earlier than expected, you’ll be dipping into your savings for a replacement sooner than you thought.

So, what’s the solution? It might not be as exciting as buying the biggest unit on the market, but getting our professionals to size up your home and recommend the perfect unit is the way to go. They’ll consider everything from the size of your home to how well it’s insulated, ensuring you get a unit that’s just right. Don't let another company upsell you on a unit that's larger than you need. Your technician should be able to explain exactly how they measured for the unit they're selling you.

In the end, while the idea of a bigger HVAC unit might seem appealing, it’s clear that bigger isn’t always better. Choosing the right size for your home is the secret to keeping your home cozy, your energy bills low, and your system running smoothly for years to come.
