Heating issues always happen on the coldest nights of winter. The wind howls, snow piles up against the windows, and your high-efficiency furnace decides to give up. Instead of feeling proud for having picked out an amazing heating system, you’re left with freezing indoors. And then you have to ensure family members have enough throws, sweaters, and blankets to make it through the night.

Today’s guide is about the hidden ways a Nor’easter can take down a modern furnace, why it happens, and when to call for emergency HVAC repair in Boston, MA.

How A Nor’easter Can Take A Smart Furnace Offline

For those new to the region, a Nor’easter is a particularly brutal coastal storm in winter. Now, coming back to the matter at hand.

High-efficiency, or ‘smart’ furnaces, are great at generating more heat out of the fuel you pay for, but they’re also more sensitive. They produce condensate that needs a proper drainage system, which calls for small-bore PVC intakes & exhaust pipes. They also use multiple sensors to ensure everything is working as it should.

During a Nor’easter, the wind piles up snow around the PVC pipes, freezing the draining condensate at the drains and terminators. The snow also forms a tight grip around the plastic and metal components exposed.

That stressful mix of conditions triggers the furnace’s safety features (again, frozen pipes), and it shuts down to prevent system overload and further damage.

Hidden Signs Of Furnace Failures Homeowners Miss | Emergency HVAC Repair In Boston, MA

Given Boston’s frigid weather, some of the worst storm-related furnace problems go unnoticed until the heat shuts down. Smart furnaces tend to produce water, which can freeze in uninsulated drainage pipes or, when it gets too cold, lock the furnace.

Snow drifts and plow piles exacerbate the issues by burying the PVC intakes or exhausts, starving the furnace of air, and trapping the exhaust until the furnace shuts down. Ice can also form on exterior vent caps, choking airflow. Those pressure shifts trip safety sensors again and again.

If your furnace keeps locking out this season, forget half measures, and treat it like an emergency HVAC repair in Boston, MA – not a mere thermostat glitch.

When Your No-Heat Night Becomes A Fully Fledged Emergency

Not all furnace operation hiccups are critical, but there are signs that warrant prompt attention.

  • The furnace shut off after a Nor’easter, and refuses to start despite a reset.
  • The thermostat reads normal, but your upstairs, or other rooms on the same floor, are icy cold.
  • The furnace is emanating whistling and rattling sounds, and there is a burnt smell indoors.
  • You’re seeing ice around the outdoor intake and exhaust pipes.

If temperatures drop quickly indoors, or you have members with delicate health, don’t ignore repeated furnace shutdowns. Your furnace is going critical.

What to Expect From A Professional Furnace Checkup | Emergency HVAC Repair in Boston, MA

Involving a trained HVAC technician means more answers than a thermostat adjustment. They’ll check for frozen and/or blocked intake and exhaust pipes. Next up is the state of the condensate tray and the drain line. Then they test flame sensors, pressure switches, and safety controls to assess what’s really shutting them down.

If furnace components are stressed or damaged, they are repaired or replaced as needed, and then the furnace gets a clean bill of health.
