Heating bills rise in winter because your home is losing heat faster than your heating system can replace it. The biggest causes are poor attic insulation, hidden air leaks, drafty windows, and heat escaping through ceilings, floors, and walls. Weatherization—adding insulation and sealing leaks—is the most effective way to lower winter energy costs and keep your home consistently warm.
What to Do About An Inefficient Home
When the first real cold front hits, most homeowners expect a bump in their heating bill—but not the shock of a bill that jumps month after month. If your heat seems to run nonstop, or your upstairs feels freezing even while the thermostat is set high, something deeper is going on.
We hear it all winter long from homeowners across Westchester County and Northern New Jersey:
“I don’t understand how my bill is this high when the house still feels cold.”
You’re not imagining it—your home is losing heat, and your heating system is fighting a losing battle.
Let’s break down what’s really driving those rising winter energy costs… and what you can do today to stop the bleeding.
The Real Reason Your Heating Bill Spikes Every Winter
Most homes lose heat far faster than the furnace or boiler can replace it. When that happens, your system works overtime:
More heating cycles per hour
Longer run times
Higher fuel/electricity use
Higher utility bills
And the most common symptom?
Cold rooms, drafty floors, uneven temperatures, and a house that never feels fully warm.
Heat loss happens because of construction gaps, old insulation, and air leaks—problems most homeowners never see until winter exposes them.
The Top 5 Causes of Heat Loss in NY & NJ Homes
1. Under-Insulated Attics (The #1 Cause of Winter Energy Waste)
Heat rises—so if your attic is under-insulated, poorly sealed, or has gaps, warm air escapes right through the top of your home.
Symptoms include:
Cold upstairs bedrooms
Hot and stuffy second floors in summer
Ice dams forming on roof edges
Heating system running constantly
Cellulose or spray foam insulation creates a thick thermal barrier that keeps warmth inside where it belongs.
2. Hidden Air Leaks Around Floors, Ceilings & Walls
Air leaks are one of the most overlooked sources of heat loss. They occur around:
Recessed lights
Outlets and switches
Attic access hatches
Basement rim joists
Top plates inside walls
These leaks create cold drafts and make certain rooms feel unbearably chilly.
Air sealing solves this quickly and dramatically reduces furnace load.
3. Drafty Windows & Doors (Not Always the Actual Problem)
Homeowners often assume the window itself is the issue—but behind the trim, framing gaps let cold air inside.
This is why replacing windows doesn’t always fix the problem.
Air sealing + weatherstripping almost always performs better for the cost.
4. Old or Settled Insulation No Longer Doing Its Job
Fiberglass insulation sags, shifts, compresses, and loses R-value over time.
When insulation settles, it creates:
Cold exterior walls
Chilly floors
Large fluctuations in room temperature
Higher winter energy bills
Most older homes in Westchester, Rockland, Bergen, and Essex County were never air sealed and now have major comfort issues because of it.
5. Basement & Crawl Space Heat Loss
If your floors feel cold or your lower level never warms up, heat is escaping downward.
Common issues:
Uninsulated rim joists
Open crawl spaces
Poorly sealed sill plates
Exposed foundation walls
Fixing these areas stabilizes the entire home’s temperature.

How Weatherization Lowers Heating Bills
Weatherization is the most effective way to reduce heat loss and restore comfort during cold months.
Here’s what it does:
● Adds insulation where heat loss is highest
Attics, walls, floors, crawl spaces—all the major escape points.
● Seals hidden air leaks
Stops drafts and prevents warm air from rushing out.
● Stabilizes room-to-room temperatures
No more freezing bedrooms or warm/cold swings.
● Improves overall heat retention
Your furnace runs less and lasts longer.
How Much Can You Save After Weatherization?
Most homeowners experience noticeable savings within their next billing cycle.
Typical results:
10%–30% lower heating bills
Better warmth retention
Shorter heating cycles
More consistent comfort across all floors
And for New York homeowners…

Rooms that never warm up
Higher bills than last winter
Furnace runs constantly
Drafts around floors or walls
Cold floors over crawl spaces
Temperature differences between floors
A winter assessment identifies heat loss quickly using:
Thermal imaging
Blower door tests
Moisture readings
R-value evaluations
Attic/basement inspection

If heat escapes through your attic, walls, or floors, your system must run longer to maintain temperature—driving up bills.
Yes. Proper insulation and air sealing can reduce heating bills 10%–30%.
Cold rooms, drafts, uneven temperatures, and high bills are the biggest signs.
Cellulose and spray foam both provide excellent heat retention for cold climates.
If your home has cold spots, drafts, or high bills, an audit identifies exactly where heat is escaping.
NYSERDA offers incentives for insulation upgrades, air sealing, and whole-home weatherization.
