What happens if furnace is oversized?
If a furnace is oversized, it can create a number of problems. An oversized furnace will run for shorter cycles, which increases the number of times the device turns on and off during the day. Being constantly turned on and off causes the furnace’s mechanical components to become overloaded and wear out quicker, leading to increased maintenance costs and possibly premature failure.
An oversized furnace can pull more air than it needs to reach the desired temperature, causing the furnace to work ineffectively and be less energy efficient. Furthermore, excessive air flow will cause rooms to become over-heated quickly and drop in temperature as soon as the furnace cycles off.
Lastly, an oversized furnace is loud and can cause significant noise pollution, making it difficult to enjoy day-to-day activities. To avoid causing these issues, it is important to have a properly sized furnace installed in a home or business.
Is it better to undersize or oversize a furnace?
Ultimately, it is always better to install an air filter or furnace of the right size for your particular environment. Oversizing a furnace can result in incomplete fuel combustion, which can lead to more frequent breakdowns, higher energy bills, and even carbon monoxide poisoning.
On the other hand, undersizing a furnace can also lead to increased energy costs. While the less powerful furnace works initially to heat the same amount of space, it will have to run for much longer periods of time at a higher capacity, leading to more frequent and longer run times, shorter lifespans, and an overall higher energy bill.
To get the most efficient heating system for your home, it is important to get an HVAC contractor to measure the size of your home and choose the best sized furnace for you.
