Comfort troubleshooting

One roomalways cold?

If the bedroom at the end of the hall never warms up, the furnace usually isn't the problem — the airflow getting there is. Here's how to narrow it down in ten minutes before you call anyone.

Check these first — 10 minutes

  • Make sure the supply vent in that room is actually open and not blocked by furniture or rugs
  • Hold a tissue at the vent — compare the airflow to a vent in a warm room
  • Swap in a fresh filter; a clogged one starves the farthest rooms first
  • Leave the room's door slightly open or check there's a gap underneath — air needs a way back out
  • Feel around windows and outlets on exterior walls for obvious drafts

Call us if you notice…

  • Weak airflow at several vents, not just one room
  • Whistling or rushing sounds when the system runs
  • The cold room sits over a garage, crawlspace or addition
  • Some rooms roasting while others stay cold, season after season
  • The problem started after a renovation or new furnace install

Why it matters

What's usually
going on.

01

Distance is everything

The farthest room from the furnace gets the weakest airflow by simple physics. It shows up first in that room — especially with a dirty filter or a partly closed vent along the way.

02

Closing vents backfires

Shutting vents in unused rooms doesn't redirect heat for free — it raises pressure in the system and can make the far rooms even weaker. Keep them open.

03

Sometimes it isn't the HVAC

Rooms over garages and older additions often lack insulation. If the airflow at the vent feels strong but the room still won't hold temperature, the room itself is losing the heat.
