5 Signs Your Furnace is Too Big for Your White Plains Home

Indeed, some things are better when bigger, but not your HVAC in White Plains, NY. Depending on the heating needs of your home, you can purchase and have a large heating system installed if advised by your HVAC contractor.

Getting the right size of a furnace is necessary to meet your home’s heating demands. Unfortunately, some homeowners are caught in the dilemma thinking whether they have an oversized or undersized furnace.


But how will you know if it’s is too big for your home? Take note of these signs!

Short Cycling

Does your furnace turn on and off every now and then? A furnace that kicks on only for a few minutes then stops all of a sudden only means one thing: your heating system isn’t the right size for your home.

If this happens repeatedly, you may need to replace your unit much sooner than expected. Large furnaces can quickly heat up your home, but will leave other areas of the house a bit colder.

Temperature Imbalances

A furnace that’s too big for your home can cause temperature inconsistencies. Even large furnaces may struggle with keeping the desired temperature in your home. You will notice that some rooms aren’t as warmer as the other rooms. In this case, you need to call your trusted HVAC company for a new heating installation in White Plains, NY.

Unnecessary High Heating Costs

When your furnace constantly goes on and off due to short cycling, your electric bills will soar high. If you noticed a sudden increase in your energy bill, your oversized heater might be to blame.

Strange Noise

A loud furnace isn’t just an annoyance, but it can be a sign of a major problem. Incorrectly-sized furnaces could be noticeable loud as there’s more air that circulates through your system more than the ducts can handle.


Mold & Humidity Issues

The growth of mold and high indoor humidity go hand in hand. Unfortunately, if your furnace is excessively big, your home’s humidity level may fluctuate persistently, resulting in humidity issues. It should take 20 to 30 minutes of cycling period to dehumidify the air indoors. But because your heating unit is oversized, it won’t be able to eliminate the water vapor completely, causing mold to form on ceilings, walls and other parts of your house. This creates a less comfortable indoor space for you and your family.
