When you invest in an oversized central air conditioner, you’re not making your home more comfortable. It’s more likely to become hotter and more humid. That’s because an oversized air conditioner:
Sure, you want your climate under control at home. The air in your home the summer should be cool and dry, and you should feel comfortable. After all, that’s what you’re paying for when you buy a new AC system!
But, there’s a limit to how big you should go.
We’ve been installing, maintaining, and replacing cooling systems in East Dundee, Barrington, and other Chicagoland suburbs for a while now. And, we’ve seen it all.
Models made for homes twice the size. Units that broke down after just a few years. Homeowners who were hot, sticky, and miserable every summer and couldn’t figure out why.
And, not all of them wanted to know the answer: Their cooling system was too powerful for their home.
Now, if the sound is especially a concern, then you should consider a ductless mini split air conditioner.
Your average central system produces sounds from 59 to 76 decibels. That range covers the loudness of people talking in a restaurant to a car going by at 65 mph.
A ductless system produces only around 20 decibels. And, that’s right near the air handler. If you’re directly under it, you’ll hear something only as loud as leaves rustling.
From across the room, they’re virtually silent.
Maybe someone sold you on a unit that’s more powerful that you need. It’s expensive, you think, but it’ll get the job done.
Well, as we reviewed already, it really won’t. And, to make matters worse, it will cost you even more in repairs and on an early replacement.
The reason is mostly because of something we mentioned already: short-cycling.
A right-sized AC will run for about 15 minutes, two or three times an hour.
But, an oversized unit blasts a lot of cool air at once, which makes the thermostat drop. But it doesn’t dehumidify or circulate all that much air.
As a result, it turns on again in a few minutes. Then a few after that. And so on.
This phenomenon is what we call short cycling. And, it leads to breakdowns and higher bills.
HVAC systems use more energy starting up than once they’re running. So, your bills go up because it turns on more often.
Meanwhile, that’s also more wear and tear on the system. It’s like highway miles versus stop-and-go city miles on your car.
It’s frustrating for homeowners: You pay more than you should up front. Then, more than you should on repairs, and finally more than you should on yet another new cooling system.
The good news is that getting the right-sized air conditioner is not a guessing game. You just need the right contractor for the job.
For instance, Compass Heating and Air starts with an intense load calculation before we even think about sitting down and talking about models, pricing, and financing.
A proper load calculation for a new central air conditioner takes into account:
All these factors weigh in heavily when deciding how powerful an air conditioner you need.
By taking these all into account, we make sure you’re making the right investment. It’s important to find the model and size that will bring you comfort for years to come without costing any more than it should.
