7 Reasons You Have Cold Spots in Your House


Winter temperatures are dropping, and heaters are working extra hard across New England. If your home is well-insulated, you’ll have an easier time staying warm. However, many homeowners face the issue of cold spots in their homes. These can occur in certain rooms or even within different areas of the same room. You might feel warm in one corner, but chilly just a few steps away!

Cold spots make it challenging to heat your home evenly. You may crank up the heater to warm a cold spot, but this often overheats the rest of your home. Besides the discomfort, your heating bills will skyrocket as you struggle to maintain even indoor temperatures. If you’re dealing with cold spots in your home, here are some common issues to investigate:

1. Improperly Sized Furnace

A furnace that’s too small for your home can leave some rooms cold. A furnace that can’t generate enough heat for your home’s square footage will struggle to keep you warm. Moreover, an undersized furnace works harder, costing you more. Consult an HVAC expert about replacing your furnace with an energy-efficient model suited to your home’s size.

2. Leaky Air Ducts

Leaky air ducts are a hidden issue that can cause cold spots and increase heating costs. This problem can affect you year-round, impacting both heating and cooling. During winter, you’ll notice some rooms are chilly while others are warm. Additionally, leaky air ducts can degrade indoor air quality, causing headaches, allergy symptoms, and increased illness, especially when your home is sealed tight. Fixing leaky ducts can improve comfort and health.

3. Improperly Sized Ductwork

Just like a mismatched furnace, improperly sized ductwork can lead to uneven heating. It forces your furnace to work harder, driving up energy costs and causing more wear and tear, leading to expensive repairs.

4. Lack of Zoning Capabilities

Without zoning capabilities, even a correctly sized furnace and ductwork can result in temperature fluctuations. Different areas of your home may be colder due to factors like large windows, high ceilings, or exposure. Zoning allows you to control the temperature in individual rooms, increasing it where needed and lowering it where it’s not. This customization can prevent overheating and ensure comfort throughout your home.

5. Faulty Thermostat

A malfunctioning thermostat can be a straightforward fix but is often overlooked. Ensure your thermostat is functioning correctly during your annual maintenance checkup.

6. Poor Home Insulation

Sometimes, the issue isn’t with your furnace or ducts but with your home’s insulation. Poor insulation can create cold spots, making your home uncomfortable and expensive to heat. Have an expert evaluate your home’s insulation to see if it needs upgrading. Though it may be a significant investment, improving insulation can save money in the long run.

7. Unchecked Air Leaks

Aside from insulation, air leaks are a major cause of cold spots. Common leak areas include vents, ductwork, windows, and doors. Simple fixes like placing towels in front of doors and using insulating drapes can help. However, for leaks around vents or ducts, professional help may be needed. These fixes are usually straightforward and improve overall comfort.

How do you determine the root cause of the problem? The best way is to schedule a maintenance and inspection appointment with a professional from MillTown Plumbing. Discuss your concerns and ensure your furnace is the right model and in good working order. This is also an excellent opportunity to explore your options for more extensive repairs or replacements. Addressing these issues can save you money on energy bills, keep your home comfortable during the winter, and eliminate cold spots.
