Why Some Rooms are Colder Than Others

It’s not your imagination, and you’re not crazy: some rooms in your home really are colder than others.

And you shouldn’t shrug it off and ignore it.

Uneven temperatures are a sign that something is wrong in your home - and you’re probably wasting money through high-energy bills.

We’ll explore the 5 causes of uneven temperatures throughout your home and how to fix them.

And you shouldn’t shrug it off and ignore it.

Uneven temperatures are a sign that something is wrong in your home - and you’re probably wasting money through high-energy bills.

We’ll explore the 5 causes of uneven temperatures throughout your home and how to fix them.

1) Closed or blocked supply air vents

Air is delivered to each room through ductwork and out a supply vent.

Make sure that none of the vents that blow air into the room are:

  • Closed (use the little lever to open it)
  • Blocked by furniture or drapes

2) Cold air leaking into the room

Cracks/openings around your window or skylight can let outside cold air into your home.

For upstairs rooms, cold air can seep in through the sides or bottom of the attic room door.

The solution: For windows with cracks, caulk them. For attic doors, add weather-stripping to the bottoms and sides.

3) Not enough insulation

Homes built before 1982 have under-insulated attics, meaning more heat escapes your upstairs rooms.

4) Leaky air ducts

Imagine a trying to transport water in a bucket with holes in it. No doubt you’d end up losing a lot of water by the time you got to your destination.

The same logic applies for leaky ductwork trying to transport air from the cooling and heating system to your rooms.

According to ENERGY STAR, the typical home loses 20% to 30% of the air moving through the duct system due to leaks and holes.

If you have these signs your air duct system is leaking, contact a professional HVAC contractor to examine your ducts and seal them if needed.

5) Furnace or heat pump turns on and off too much

Is your heating system turning on and off too frequently? That means it’s short cycling and can’t circulate enough heated air around your home.

3 causes of short cycling:
