Cold Snaps and Stubborn Furnaces in Peachtree Corners

Most of the year a furnace in this part of Gwinnett just sits there while the AC does the work. Then the first real cold front blows through, somebody nudges the thermostat to heat, and the furnace is expected to fire right up after months of doing nothing. A lot of the time it does not. You hear the draft fan spin, a click, maybe a glow through the little window, and then silence. Or the blower kicks on and the air out of the registers is barely warmer than the hall. Or the flame catches, holds for a few minutes, cuts out and the whole routine repeats. My crew does not guess at furnaces, because guessing means you pay for parts you did not need. On gas equipment we go in order: hot surface igniter, flame sensor, draft inducer and its pressure switch, high limit and rollout switches, gas valve, flue and whatever code the board is flashing. On electric furnaces and air handlers it is heat strips, sequencers, relays and the blower. Short cycling usually means the furnace is running too hot because of a clogged filter, shut registers or a lazy blower, and the limit switch is protecting the heat exchanger by shutting it off, so we fix the reason it is running hot rather than just resetting it. In a two-story house there is one more wrinkle: heat climbs, so the downstairs can feel cold even with a healthy furnace, and that calls for an airflow check too. And the one rule that never bends: if you smell gas, leave the thermostat and light switches alone, get everybody outside, call the gas company or 911 from the yard and ring us once it is safe.

Furnace Parts My Peachtree Corners Crew Tests

These are where no-heat and not-enough-heat problems usually turn up.

  • Hot surface igniter

    Cracked or tired igniters replaced so the burners catch on the first try.

  • Flame sensor

    Cleaned or swapped when the furnace lights and then shuts the flame off a few seconds later.

  • Draft inducer and switch

    Inducer motors and pressure switches checked when the furnace stalls before ignition.

  • Overheat shutdowns

    The cause behind a tripped limit found, from a clogged filter to closed registers or a weak blower.

  • Blower and capacitor

    Blower motors, capacitors and wheels tested so heat actually reaches the far rooms.

  • Electric heat strips

    Elements, sequencers and relays put on the meter in electric furnaces and air handlers.

  • Board error codes

    Flash codes read and tracked to the failing part, especially on problems that come and go.

  • Flue and safety controls

    Burners, venting and every safety switch verified before the furnace goes back to work.

Working a No-Heat Call in Peachtree Corners

  1. Tell us what you heard

    Clicks with no flame, cold air from the vents, a furnace that starts and stops. Those clues point the tech in the right direction.

  2. Run the startup, part by part

    The furnace is cycled while each stage is tested. You hear the failed part and the price before anything is replaced.

  3. Repair, then safety-check

    After the fix, the furnace runs several cycles while burners, venting and safeties are verified, so it keeps going on the next cold night.

Why Homeowners Call My Crew When It Gets Cold

  • Tested in order

    Every stage of the startup gets checked, so you do not pay for parts that were never the problem.

  • Safety on every furnace

    Venting and safety controls get looked at on each repair, not only the part that failed.

  • A voice at night

    If the heat quits after hours, the emergency number is staffed around the clock.

  • Gas and electric heat
  • Venting checked every time
  • Price before parts
  • Homes and offices
