Furnace Repair can be complicated and hazardous if you do not know what you are doing. Hiring a professional HVAC contractor is always the safer option, especially if your furnace is still under warranty. Professionals follow safety protocols and building codes, minimizing risks. In addition, they have extensive knowledge of different models and can quickly diagnose problems. In some cases, a professional can save you time and money by diagnosing a problem before it worsens, allowing you to schedule repairs more promptly.
While many healthy furnaces maintain a consistent whirring sound, strange noises such as banging, rattling, irregular humming, and groans are signs that something is wrong. These sounds can indicate that the heating system is in need of an emergency repair or replacement. The Spruce, a website dedicated to offering practical tips and real-life advice, came up with a list of common furnace noises that you should be aware of so that you can better describe the problem when contacting a Furnace Repair specialist.
The blower keeps running
The most obvious sign of a furnace problem is the blower continually running. If this is the case, it’s likely that one of your air ducts has something blocking it or that your furnace is experiencing a power issue. You should check your ductwork regularly for any obstructions such as a curtain or piece of furniture that may be blocking the vents. You should also make sure that your thermostat is set to HEAT, not COOL, and that the fan is on AUTO, not ON.
If the blower continues to run, you should first turn off the gas supply (if possible) and the power to your furnace. Then, use a flashlight to check for a pilot light that has gone out. If you can’t find a flame sensor, turn off the power to your furnace by shutting off the switch at the unit itself or at your home’s main electrical panel. Then, use a 1/4″ hex-head screwdriver to remove the burner flame sensor, which is a thin metal rod that’s located at the burner assembly. Be careful because the flame sensor is extremely hot. Clean off any dust or dirt with a paper towel and then replace the burner flame sensor.
Attempting to relight the pilot may seem obvious, but it’s important to know that you must do this safely. You must turn off the gas supply and wait several minutes to ensure that no flammable natural gas has built up around your furnace. After a few minutes, you can then turn the gas back on and start relighting the pilot.
Furnaces don’t last forever and they all eventually require some type of Furnace Repair. Performing regular maintenance and addressing any issues as soon as they arise will increase the longevity of your unit, improve house comfort, and help reduce your utility bills. Unless you are an experienced DIYer, it is best to leave any significant work to the professionals.
