Bigger Isn’t Always Better
We all know the old saying, “bigger is better,” but in terms of HVAC, this is absolutely not true. Some companies may try to tell you this, but you could be facing a world of trouble if you install an HVAC unit that is too big for your home. One big issue with an AC that’s too large is that it’s constantly running on short cycles. Air conditioners are programmed to run until a home reaches the temperature set on the thermostat. Once the home reaches that temperature, the whole system turns off. While this may sound fine, in truth, when a system is too large it’s constantly turning on and off because it cools the home in a much shorter cycle. Over time this will cost a ton of money and leave significant wear and tear on your system.
Another issue with a too large air conditioner is high humidity and the possibility of mold. When the AC short cycles, like we mentioned above, it doesn’t have the chance to properly remove moisture from the air, leaving your home with high indoor humidity. This humidity can cause mold to grow on your ceilings or walls.
