Most people in Sagle, when they choose a new furnace, think that “bigger is better”. However, an oversized furnace can present just as many if not more problems than an undersized furnace. So, if you feel you may have overdone it in the past or you want to avoid making a mistake in the future, here are some signs that your furnace may be oversized.
The most common sign of oversizing is short cycling. Short cycling occurs when your furnace turns on and off frequently because it reaches the thermostat setting so fast. Basically, your furnace is so powerful that it can produce what you need rapidly and then shuts off. But, because it does this, the temperature in your home is likely to cool much faster as well since the furnace isn’t on all the time.
Additionally, the on and off short cycling has a negative effect on your furnace, causing excess wear and tear on the system and eventually leading to extra repairs and in some cases early replacement.
High and Low Temperatures
When your furnace is turned on for a comfortable indoor temperature like 70 degrees F, the high and low temperature between cycles should be relatively close to that temperature. In an ideal situation, you shouldn’t even notice a fluctuation.
So, if the high temperature gets close to 75 degrees F and the low temperature is around 66 degrees F, you have a furnace much too large for the size of your home.
Furnace Room Issues
You might find that the space and exhaust given for the furnace are not sufficient either, especially if your previous furnace was replaced with this oversized unit. Backflow of a gas or oil smell or excess heat in and near your furnace room are both common signs that the furnace is much too large.
So, what should you do about your oversized furnace? If you have had that furnace for some time or just moved into a new home, it’s a good idea to have a new one installed. Have a proper load calculation done and then get a new furnace installed so you don’t have to worry about the system cycling on and off so often. If it’s a newer unit, call your Sagle heating technician and discuss possible options to reduce the negative effects of the miscalculation of its size.
