Signs Your Boiler Needs Repair

Boilers use fuel like natural gas to heat water, which is circulated throughout the building to provide heat. While the process may seem simple, boilers are actually quite complex, and a problem in any of the main components like the burner tubes, the water regulator, pressure switches, pumps, or combustion controls may render the system inoperable. Here are some common signs that your boiler needs repair:

  1. It's not putting out enough heat to reach the target temperature on the thermostat
  2. The unit refuses to start or shuts off at random
  3. Breakers and safety devices trip when it's turned on
  4. Water is pooling around it or leaking from your pipes
  5. The system seems to be constantly refilling
  6. You hear strange noises or clunking sounds
  7. The smell of sulfur, burning, or mildew becomes evident

If you notice any of the above items, don't worry. Give (847) 722-0000 a call and we'll come out. Our boiler repair experts work in Northbrook, Buffalo Grove, Wheeling, and beyond.

The Most Common Causes of Boiler Failure

Is your boiler not producing heat? Are there cold spots on your radiator or strange noises from your pipes? Diagnosing the causes of these issues takes an expert's eye. This is because the complexity of boilers often makes pinpointing the root of a problem difficult. We find many boiler issues in the Northbrook and Wheeling areas are caused by:

  • Broken Pilot Lights: Without a functioning pilot light, your boiler can't heat its fuel source. Though sometimes caused by a dirty burner, it's typically the result of a broken thermocouple.
  • Frozen Condensate Pipes: Condensate pipes transport acidic water produced by the boiler to an outside drain. In extreme cold, this pipe can freeze and burst. This will produce an error code and alert you to a need for an HVAC technician.
  • Excess Pressure: If your pressure gauge reads below “1” or in the red, your system is having a pressure problem. This can be caused by a water leak, faulty pressure relief valve, or excess air in the system. The best way to pinpoint the problem is to give Master Mechanical—Buffalo Grove's boiler repair experts—a call.
  • Kettling: If your boiler’s making a deep rumbling sound, like a tea kettle on the verge of whistling, you have a pretty serious heating problem. This is typically caused by sludge or scale build-up on the heat exchanger. This obstructs the water, leading to kettling and whistling.
  • Boiler Leaks: The most obvious sign of a boiler system is a leak. These can be a real nuisance, not only because of the water damage but because of the electrical malfunctions which typically follow.

Though boilers can fail throughout the heating system, problems typically occur at the beginning of winter after a long period of disuse. The sudden pressure on the system often strains worn out components leading to system failures. To stop your family from losing heat when you need it most, we suggest scheduling boiler maintenance annually.

Proof We’re the Best HVAC Company Straight From Our Customers

  • Didn’t Push a Furnace Replacement
    Taylor D.
    Tom, the owner was awesome. He came out immediately when our furnace went out and completed a challenging fix. When I asked if I should replace the furnace he said no. Honest and did outstanding work. Furnace is quieter and seems to be running better than when we moved in!
  • Highly Recommended for AC Replacement
    Jeremiah D.
    Tom came over and thoroughly discussed my options. We discussed at length the pros and cons of the most expensive and least expensive options, and came up with a fair price for the products I chose. The crew showed up on time and finished the same day, and was easy to deal with. The new furnace heats my house so much better than the old one. I would definitely use Master Mechanical again. And I have. I’ve now replaced multiple furnaces and AC units using Tom and his crew at Master Mechanical, and would use them again.
  • Quick AC Fix During a Power Surge
    Jim P.
    Master Mechanical responded quickly when our AC failed following a power surge. They quickly diagnosed the problem, and responded patiently to my uninformed consumer questions. Once the team arrived to complete the repair work, they were professional and again, knowledgeable. Prices were fair, and they followed up with me after work was completed. Overall a great company!

  • Two Great HVAC Experiences
    Bill L.
    Did an excellent job on two repairs. The first was an emergency call for a furnace repair when it was 4 degrees F outside. They showed up on time, diagnosed the problem, went for parts, repaired the furnace all in about an hours time. The second repair was for the whole house humidifier attached to the furnace. It was a minor issue and corrected in less than 40 minutes. Everything is working great. My experience with their work is excellent.
