Is a Bigger Furnace Better? Three Recurrent Issues You Experience Using the Wrong Unit Size

Since Winter is coming up, you need to have your indoor heating system in the best condition. The furnace is an instrumental component of the indoor heating process during the cold season. Most people believe that they should pay for the largest furnace in the market. However, the size of the furnace does not always translate into efficiency. You might find your furnace breaking down more often than it did before because of issues with the size. Here are some of the damages that result from a wrong furnace size and how to handle them. 

Short Cycling

Short cycling is when the furnace keeps turning off too quickly, even before the house has reached the temperature set on the thermostat. It happens because the furnace is constantly overheating. Since it is too big for your home, it will generate more heat than your house needs when you switch it on. The heat will build up, forcing the furnace to shut down and start a cooling cycle. You end up with a home that is not heating up as it should. A heating contractor can assess the cycling problem and help you determine whether there is something they can do about the unit size. 

Damaged Heat Exchanger

The heat exchanger is a crucial component of the unit. When it is larger than your heating load, you strain the heat exchanger to a point where it completely breaks down. You will know that you have a damaged heat exchanger when you start experiencing strange smells in the home or soot starts building up in the components. You might also notice changes in the color of the flame, and it may burn with unusual sounds. A technician will assess the cause of the heat exchanger problem and recommend a solution before it ruins the entire furnace. 

Issues With the Thermostat

The thermostat is another source of issues when you have an oversize furnace. You will find some parts of your home heating up faster than others. Your house will stay cold if the thermostat gets installed in a room that heats up faster than others. It will also overheat when the thermostat is in a room that takes time to heat.

Only a furnace expert can gauge the size of your unit and determine whether it is the reason behind the frequent break-downs. They will recommend the best furnace repairs after the diagnosis.
