Bristol County Furnace Repair & Replacement Services

When your furnace isn’t working the way it should, it can turn your cozy home into an uncomfortable (and potentially unsafe) space, especially during the coldest months of the year. That’s where Cotti Johnson HVAC, Inc. comes in. As a leading furnace contractor, we specialize in fast, reliable furnace repair and replacement services to keep your home warm and energy-efficient all season long. Our expert technicians can solve furnace issues like:

  • Dirty or Clogged Filters: A dirty filter restricts airflow, causing your furnace to work harder than necessary and possibly overheat or shut down.
  • Ignition or Pilot Light Issues: Whether it’s a faulty ignitor, thermocouple, or pilot light, ignition problems can stop your furnace from producing heat altogether.
  • Malfunctioning Thermostat: If your thermostat isn’t working correctly, it can lead to uneven heating or your furnace not turning on at all.
  • Blower Motor Failures: The blower motor pushes heated air through your home. If it fails, you’ll notice weak airflow—or none at all.
  • Cracked Heat Exchanger: This is a serious issue that can lead to carbon monoxide leaks. A cracked heat exchanger often requires a full system replacement.
  • Frequent Cycling: If your furnace is turning on and off too often, it might be due to a dirty filter, thermostat issues, or poor airflow.
