Installation & Replacement

Whether installing a heating system for a new build or replacing an outdated unit, a furnace is always an excellent choice. When selecting a new furnace, consider making the switch to natural gas. This clean, affordable, and safe choice is highly energy-efficient and can reduce heating costs by 50% to 70%.

With the cost of electricity always rising, natural gas is a great value. In addition to greater efficiency, you’ll also get greater comfort and reliability, as gas furnaces offer superior warmth and even the ability to heat your home during a power outage. Plus, natural gas burns cleaner than oil, wood, or electricity produced from fossil fuel, making it an eco-friendly option.

5 Signs Repair Is Needed

If your furnace is no longer operating at peak performance, it may be time for repairs. Signs you may need to call a professional include:

  • Gas leaks: If you suspect you have a gas leak, turn off the furnace, evacuate your home, and contact National for professional repairs.
  • Strange smells: Odd smells could be a sign of poor combustion or simple dust in the unit and should be assessed by a professional.
  • Uneven heating: If you have hot or cold spots in your home, you could have issues with the system or a duct leak.
  • Discolored pilot light: A pilot light that isn’t burning blue is a sign that you have a ventilation issue.
  • Reduced air quality: Excess dust or increased allergies may be signs that your furnace is blowing dirt, bacteria, and more into your air.

If you’re experiencing these issues, call (513) 621-4620 to schedule gas furnace services today.
