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.

Great Service that exceeded my expectations!!




This is by far the best HVAC company I have used. Erwin was professional, knowledgeable and extremely thorough. He did such a great job that I signed up for their maintenance contract to ensure my systems are always operating at their optimum level.

Terrific and Fast Service




Erwin worked diligently on repairing several aspects of our air conditioning system. He was very professional, showing me the damage to our units and explaining how the components work together to efficiently and safely provide AC to our home. I've never had a technician be so thorough and explain what needed to be done in such a comprehensive and easy to understand way. I really appreciated all his hard work and thoroughness especially on a very hot day!

HVAC Service Call




I highly recommend this company for your HVAC needs! What a tremendous effort by the HVAC Unlimited Team supporting our requirements. I called several other companies who either did not return my call or had excessive emergency rates. The HVAC Unlimited Team was timely, professional, and provided exceptional customer service. The HVAC representative (Jeremy G.) was a total pro -- he kept me informed on his arrival time, provided detailed analysis of the diagnosis, and walked me through the process of bringing my HVAC back to a fully mission capable state. Further, Jeremy was very patient and answered the plethora of questions I had regarding my system and provided information on routine service opportunities that the company can provide. If you are in need of HVAC support, don't hesitate any further, call this team and you will be in good hands.
