Having a furnace that’s too big for your space is extremely inefficient. There are two simple signs that indicate that your furnace is most likely oversized:

An oversized furnace has short run times (or “short cycles”) because it’s quickly heating your home to the thermostat’s temperature setting. By short, we’re talking 10-15 minutes. Now, that seems like a good thing (especially on frigid nights), but it’s not for a few reasons:
The AFUE rating (the efficiency rating) you see on your furnace assumes your furnace is running at a “steady-state operation” (basically like a car’s mileage on the highway).
But an oversized furnace will come on and cycle off before it can reach that steady-state operation level of efficiency. So you’ve got several short, inefficient bursts wreaking havoc on your energy bill. Think of this as the furnace’s version of “city miles.”
If your furnace is properly sized, it will stay on longer, running almost constantly on the coldest days. Visit another one of our blog posts so you can understand your furnace’s AFUE rating to get big winter savings!
Short cycling wears down the mechanical parts of your furnace. It’s like if you constantly turned your car off and on every time you came to a stop light.
Do you feel a massive heat blast coming from vents in certain rooms?
Once again, the oversized furnace strikes! Its heat output is far more than your home actually needs, so you’re left with a heat hurricane in certain rooms. Ironically, an oversized furnace can cause rooms farther away from the thermostat to be too cool for comfort.
Because when the furnace cycles off your home cools down from the outside in. By the time your thermostat, which is located on an interior room wall, feels a temperature difference and turns the furnace back on, the rooms farther away have already cooled down a good 5-7 degrees.
If your furnace is properly sized, it should have longer run times, distributing heated air more evenly throughout your home. Learn more about why some rooms in your home are colder than others here!

Francis from Nicholson Plumbing and Heating was excellent. He was here to evaluate HVAC in our home. He was very patient and answered all my questions. He is also polite and easy to communicate with him. He explained technical concepts to me in layperson terms!

Nicholson offered what is possibly the best customer service I have dealt with in a home repair situation. I called them because I was looking to replace my very old furnace. They came out to do an initial estimate, and then came back when I had some further questions about my options. After installing the furnace, they ran into some problems with my air ducts. This happened on a Friday, and the problem was fixed by Monday afternoon. In addition to their excellent service, they did quality work at a fair price. I would recommend them to anyone looking for an HVAC company in the Framingham area!

Recently used these guys because my HVAC unit AC wasn’t working (first hot day of summer). Showed up on time, wore booties, fixed the unit. During the visit we talked about how my unit was having problems in the winter – which was resulting in NSTAR service calls of maybe 3-4 times per season (I am on a service plan with them). He was the first guy to tell me WHY the problem was happening, and HOW to fix it. I find it strange that all of the NSTAR guys etc. no one took time to point out how to fix the source of the problem…Very professional, smart. I would use them again, and plan to for the fix on my heating unit!
