Furnace & Heating Repair in Marietta, GA

Reliable furnace and heating repair across Marietta and Metro Atlanta — fast response when a cold snap hits, with safety-first diagnostics and upfront pricing.

Georgia winters are mild until they aren't. When a sudden cold snap or ice storm rolls through and your furnace won't keep up, Ultimate Home Services Plus is the local team that responds fast — and puts your family's safety first.

Here's the thing about heating systems in the Atlanta metro: they sit unused for much of the year, then get pushed hard the moment temperatures drop. That on-and-off pattern is exactly when worn igniters, flame sensors, and blower components give out. A furnace that worked fine last week can fail on the first truly cold night — usually when you need it most.

Signs Your Furnace Needs Repair

  • No heat or weak heat — the furnace runs but the house won't warm up.
  • Short cycling — it turns on and off repeatedly without completing a cycle.
  • Banging, squealing, or rattling when it starts or runs.
  • The blower won't shut off or runs cold.
  • A yellow or flickering burner flame instead of steady blue.
  • Rising heating bills or a burning/musty smell when it kicks on.
Safety first: if you smell gas or suspect carbon monoxide (headaches, dizziness, a CO alarm), leave the home and call us — and your gas utility — right away. A cracked heat exchanger is a serious hazard we check for on every visit.

What Our Heating Repair Covers

Whether you have a gas or electric furnace, we diagnose the real cause before quoting any work. A typical visit checks:

  • Igniter, pilot, and flame sensor — the most common no-heat culprits.
  • Gas valve and burners for safe, clean combustion.
  • Heat exchanger inspection for cracks (a carbon-monoxide safety check).
  • Blower motor and capacitor performance and amp draw.
  • Thermostat and safety controls testing and calibration.
  • Airflow and filters — restricted airflow causes many heating failures.

Furnace Repair FAQs

It depends on the failed part — an igniter or flame sensor is on the lower end, while a blower motor or gas valve costs more. We diagnose first and give you the exact price before any work begins.
Confirm the thermostat is set to heat, check that the furnace switch and breaker are on, and replace a dirty filter. If it still won't fire, it's often the igniter or flame sensor — give us a call.
Yes — treat it seriously. Leave the home, avoid switches or flames, and call your gas utility and us right away. We always inspect for combustion and carbon-monoxide safety.
If your furnace is under about 15 years old and the repair is minor, repair usually wins. For older units, a cracked heat exchanger, or repeat failures, replacement is often safer and more cost-effective. We'll give you an honest recommendation.
