Signs You Need Boiler Repair

There are lots of indications that something may be wrong with your boiler. Keep an eye out for any of these signs:

  • Odd sounds. One of the first (and too often, the last!) indications that something has gone awry, odd sounds should never be ignored. Sounds may indicate a number of problems, such as the clunking of a deposit buildup in the tank, or a squeal or thin whine when a component has become damaged. Odd sounds can be very serious, and left alone could cause huge issues.
  • Leaking. A leak can lead to increased costs, and if left alone, can create an opportunity for even further damage. Have it checked and handled by a professional immediately.
  • Unusual odor. Really with a boiler, any smell at all should be unusual. If you smell anything strange, particularly sulfurous (rotten eggs) or metallic odors, seek professional assistance now. This could be a serious health risk!
  • Older boilers. Boilers are built to last, but that doesn’t mean they’ll last forever. After even ten years, your boiler should be routinely checked and repaired by a trained professional. If it’s really getting up there in years, you may even consider boiler replacement to increase efficiency and reduce the frequency of boiler repair.

Jermaine Rocks the House




Amazing work by this tech. He was able to diagnose and resolve a faulty HVAC installation (performed by a competitor company), which had resulted in massively sweaty (condensation-soaked) ducts. He was knowledgeable, highly skilled, efficient...,and a very cool guy. Highly recommended.

Rony showed up on time, investigated and diagnosed the problem with my AC unit very quickly. He also fixed it quickly and provided me with tips to keep the drain clean.
