Issues Caused By An Oversized Furnace

When it comes to buying a furnace for your home, bigger is not always better. Although many home owners mistakenly believe that a larger unit will be more productive, installing a furnace that is too big for the area in which it will operate can cause a multitude of problems. For this reason, furnaces come in a variety of sizes to suit the needs of different properties, lifestyles, and environments. If you have noticed an increase in your utility bill or extreme temperature changes in your home, you might want to consider replacing your furnace. As you are looking for a new one, here are a few of the issues caused by an oversized furnace to keep in mind.


Extra Wear and Tear

Installing and operating an oversized furnace in a room that is not large enough can lead to the unit experiencing a much quicker breakdown and requiring more frequent maintenance and Winnipeg furnace repair due to the extra wear and tear it will suffer. This is a result of rapid heating cycles that are caused by the furnace shutting down more often as it reaches set temperatures more quickly in a room that is too small to accommodate a larger system. When you choose a furnace that is properly sized for the room in which it will be installed, the burn stage of the system will run far more efficiently throughout the day, lessening the burden on your unit over time and reducing the frequency of costly maintenance.


Increased Heating Costs

When an oversized furnace experiences more rapid heating cycles in a room that is too small, the constant starting and stopping consumes more fuel on a regular basis and increases your heating costs because the system is unable to reach peak efficiency. As the furnace begins to heat up, it cannot run adequately because the air leaving the unit must achieve a steady value before it will operate at its set efficiency levels. Since an overly large furnace runs more frequently on the warming up mode, it will not shut off until the system reaches a consistent temperature. Unfortunately, the only way to fix an issue like this is to have your furnace replaced with a properly sized unit by trained professionals.


Uncomfortable Temperatures

With an oversized furnace in place, the temperatures in the different rooms of your house may vary wildly during the heating cycle because the thermostat heats up too quickly, resulting in an uneven distribution of warmth throughout your home. When the thermostat gets too hot, the furnace may shut off before all of your rooms receive the proper amount of heat, leaving them uncomfortably hot or cold. To avoid this problem in the future, contact a qualified furnace installation professional to calculate your required heating space and ensure that you choose an appropriately sized system for your home.
