4 Signs That Your Heating System Needs a Professional Maintenance Service

A well-maintained heater or furnace is crucial to preventing serious technical issues that can pose health hazards to your family. The latest versions of heating systems are more efficient and last longer than their older counterparts. However, in the absence of regular maintenance, these systems may develop problems and cease functioning properly. Harsh weather conditions and improper heat settings can also aggravate the damage. 


Thankfully, heating systems do not suddenly break down. According to HVAC professionals offering heating system repair services in Stockbridge, the system may exhibit several signs that maintenance and repair are long overdue. Once you know what signs to watch out for, it is easy to call in HVAC technicians to take a look at your heating system.


So here are four common signs that indicate it is time to get professional service for your heating system.


1)  Unusual noises from the heating system

If all is well, heating systems do not produce much sound while starting up, shutting down, or functioning. So, strange sounds from the heating system are a sign that something is off. Remember that ignoring these noises could lead to more costly repairs in the future.


If your heating system is making audible rattling, screeching, grinding, or banging noises, it is time to get it checked by an HVAC expert. While rattling may indicate a problem with the blower motor, a squealing noise might point to loose bearings in the motor.


2) Sudden spike in energy bills

Winter has been here for a couple of months, and if you have noticed unusually high energy bills, the culprit could be a malfunctioning heating system. Several reasons may contribute to an inefficient heater or furnace. It could be clogged filters, motor damage, or leakages in air ducts. Neglecting it can cause your heater to gradually become weaker and incapable of providing adequate heating.


When you suddenly begin receiving high energy bills, it would be a good idea to get in touch with the best heating system services in Stockbridge and have your heating system checked thoroughly.

3) Watch out for yellow pilot light


Ideally, your furnace must have a blue pilot light. If it appears orange, yellow, green, red, or purple, it indicates flaws in your heating system. Usually, it points to residues of rust or tar. However, yellow light can indicate something more serious – a carbon monoxide leak that can be deadly. If your carbon monoxide alarm has gone off, you must immediately evacuate your home and access emergency services provided by HVAC professionals.


4) Odors of gas leaks

If you smell gas within the house, it is a clear indication of a malfunctioning heating system. Switch off the furnace at once to avoid any disasters due to the highly inflammable gas. It is also recommended that you evacuate everyone from the house and call in HVAC technicians from heating system emergency services in Stockbridge as soon as possible. The HVAC experts are trained to locate leaks and conduct necessary repairs to ensure your home is safe again.
