Signs You Need Franconia Gas Furnace Repair

How do you know you need gas furnace repairs in Franconia? Look for the following signs, and make an appointment as soon as possible!

  • Weak heating. If your furnace can’t keep up with the demands placed on it, it’s likely that something has gone awry. Call on a professional to assess the problem right away.
  • Odd sounds. During normal operation, your furnace makes a minimal but noticeable amount of noise. but if you notice a clunk, bang or whistle that wasn’t there before, there is a good chance a component has become damaged. This is a particularly insidious issue, as loose or damaged components pose a risk to the rest of your system’s parts.
  • Increase in the cost of heating your home. Many aspects of a gas furnace can affect its efficiency and ability to operate effectively. If you notice a spike in your monthly heating costs, the furnace is likely at fault.
  • Off-color pilot light. The pilot can serve as an ideal gauge for the balance of gasses in your furnace. An optimal burn is blue, indicating that all is well. But a yellow, or orangeish light likely means something is amiss with the gas in your furnace. Have this issue checked immediately!
  • Over-frequent cycling. When your furnace is having trouble stabilizing the temperature in your home, you may notice it turning on and off far more frequently. This can mean something is affecting the efficiency of your unit, or it may indicate faulty wiring, or an unresponsive thermostat.
