Common Boiler Problems We Fix
Boiler problems can range from minor performance issues to mechanical faults that affect your entire heating system. Tamas Mechanical diagnoses and repairs common boiler issues to help restore consistent heat, improve efficiency, and prevent further damage.
Boiler Not Producing Enough Heat
Sometimes, radiators remain cold or your home takes too long to warm up. In this case, your boiler may have a faulty thermostat, circulation pump, or another malfunctioning internal component.
Boiler Leaks and Dripping Water
Water around your boiler may indicate damaged seals or loose connections. A faulty pressure relief valve or corrosion are other possible reasons.
Low or Fluctuating Boiler Pressure
A boiler that repeatedly loses pressure may have a leak, an expansion vessel problem, or a faulty pressure relief valve. This may lead to a banging sound later on.
Strange Banging, Gurgling, or Whistling Noises
Unusual boiler noises can result from trapped air, restricted water flow, mineral buildup, or pump problems. We assess the source of the noise and repair the affected components to help restore quieter, more reliable operation.
Boiler Keeps Switching Off
Frequent shutdowns may be caused by overheating, low water pressure, circulation problems, or a faulty sensor. Our technicians troubleshoot the system, identify the reason for repeated lockouts, and carry out the required repairs.
Pilot Light or Ignition Problems
If your boiler struggles to ignite or repeatedly loses its pilot light, the cause could involve the ignition system, flame sensor, gas supply, or related components. Fortunately, ignition problems are easy to identify. You should consult a technician right away.
Uneven Heating Throughout Your Home
If some rooms are warm while others remain cold, the problem may involve poor circulation, air in the heating system, a malfunctioning pump, or an issue with the zone controls. We inspect the system to help restore balanced heat distribution.
Rising Energy Bills
A boiler that uses more energy without delivering better heating may have a faulty component, restricted circulation, or another efficiency-related problem. We investigate the cause and recommend repairs that can improve performance and reduce unnecessary energy waste.
Boiler Repair vs. Replacement:
Which Is Right for You?
Deciding whether to repair or replace your boiler depends on its age, overall condition, repair history, and operating costs. Tamas Mechanical evaluates these factors to help you choose a practical solution without recommending a replacement when a reliable repair is still possible.
When Boiler Repair Makes Sense
Repair is often the better option when your boiler is relatively young, has a sound heat exchanger, and has developed an isolated fault. Replacing a thermostat, circulation pump, sensor, or valve may restore performance without the expense of installing a new system. A repair may also make financial sense when the boiler has been maintained regularly and continues to heat your home efficiently.
When Boiler Replacement May Be Better
Signs You Need Boiler Repair Now
Some boiler problems can wait for a scheduled appointment, but others require immediate attention. Recognizing these warning signs early can help prevent more extensive damage and protect your household.
No Heat During Cold Weather
If your boiler stops working during freezing weather, indoor temperatures can drop quickly, increasing discomfort and the risk of frozen pipes. Arrange prompt professional service to identify the cause and restore heating.
Water Leaking From the Boiler
Visible leaks should never be ignored, especially if water is reaching electrical components or causing damage nearby. Turn off the system if it is safe to do so and arrange an inspection.
Gas Smell or Carbon Monoxide Alarm
A gas smell or carbon monoxide alarm may indicate a serious safety hazard. Leave the building immediately, avoid operating electrical switches or open flames, and contact your gas utility or emergency services from a safe location. Do not re-enter until authorities say it is safe.
Repeated Shutdowns or Error Codes
A boiler that repeatedly locks out or displays persistent fault codes may have a problem with its ignition, pressure, sensors, or circulation system. Avoid repeatedly resetting it and arrange professional diagnosis.
Loud Banging or Boiling Sounds
Persistent banging, kettling, or unusually loud operating noises may indicate restricted circulation, overheating, or mineral buildup. Stop using the boiler if you suspect overheating and contact a qualified technician.
Sudden Loss of Hot Water
If your boiler also supplies domestic hot water, a sudden loss of hot water may point to an ignition fault, diverter valve issue, or another component failure. A professional inspection can determine whether the problem requires immediate repair.
Emergency Boiler Repair in Mississauga
A boiler breakdown during a cold Canadian winter can quickly become more than an inconvenience. When your heating system fails unexpectedly, Tamas Mechanical provides prompt boiler repair services to help homeowners and businesses address urgent heating problems. Our technicians diagnose boiler faults, assess safety concerns, and recommend appropriate repairs to restore dependable heating whenever possible.
When to Request Emergency Boiler Service
- Boiler stops heating during freezing weather.
- Boiler develops a significant water leak.
- Boiler repeatedly shuts down.

Needed help getting our air conditioner working again, great service. Tamer knows his stuff, was thorough, clean and explained everything he was doing as he went along.
I've been having issues with poor airflow at a number of my vents in addition to some freezing in my furnace room in my home in Mississauga. I found Tamas Mechanical online. They have great reviews, and after speaking with Tamer and having him complete his diagnostic, I see why. Tamer was professional, patient, and fair throughout my engagement with him.Tamer quickly identified the issue and tweaked some settings to resolve it. I will be going back to Tamer for all my HVAC needs going forward!
Overall I had an excellent experience with Tamer installing a smart thermostat in my home. He was very polite, organized, knowledgeable and very easy to work with throughout the process. I have already booked him in to service the furnace for next season. I would highly recommend hiring him for any work needed.
The gentleman was very knowledgeable, experienced and extremely helpful. He was fast in repairing my gas leaking pipe. I plan to use him again in the future. His company deals with gas leaks, furnace maintenance, duct cleaning and air conditioning maintenance. I'm a very satisfied customer.
Tamer was excellent in diagnosing and fixing a complicated furnace issue we had. This was not my first time using Tamer and it won’t be my last. He is our go to guy for HVAC. Very professional, conscientious and good at what he does. Would highly recommend.
I hired Tamas Mechanical Inc., for furnace and duct cleaning. Tamer’s team, Mahdi and Blessing, did a great job. Mahdi was careful and efficient with his work. I also appreciated that they were respectful of us and cleaned up after the service. Tamer was very responsive when I was inquiring and booking. Had a smooth and easy experience with them. I highly recommend these guys and would hire them again in the future.
Tamer did the job perfectly, he came ontime and his dedication to do task properly was obvious. Highly recommended
Had a great experience with this company. I was having a BBQ at my new house in a couple of days and needed an HVAC company to install a new natural gas line for my BBQ. I put a request in Homwstars and got a call from Tamas very quickly and arranged for a technician to arrive the next day and provided a quote over the phone based on some photos and measurements. Tamer was the technician and took about half a day to install the new line which worked perfectly. One small issue was that my fireplace pilot went out during the installatio and I couldn't relight it. But Tamer came back to do a manual light at no extra charge. Very happy with the service, price and friendliness of staff.
Tamer was a helpful guy. Helped fix my problem within a couple of hours. Would recommend him for any hvac issues.
I was struck by how honest he was. Didn’t charge me for a small task months ago and quickly resolved an issue today. Good workmanship and great value. I’m happy to rely on Tamas for my HVAC needs.
Tamer is great and makes sure all your equipment is in running order. Way better deal than something like Reliance. Here is the Bryant AC unit that he installed for us.
Tamas Mechanical provided great service. Was able to get a quote over the phone with a few pictures and have them completed 2 days later. Amazing work!
We needed repair work done on our HVAC/furnace. He was quick to respond, and quick to get to the repair. The price was very reasonable for great and honest work. Tamer was exceptionally knowledgeable and will not give empty promises. He was detailed and transparent in showing and explaining what the problem is, what he would recommend, and also allowed me the option to choose which route I wanted to take to truly fix the problem. He does not give you the run-around and works as quickly as possible without compromising quality. We felt like we were truly taken cared of. On top of that, the repair was flawless! We highly recommend Tamas Mechanical, and will gladly use his service again (should we need future repairs/ installations).
Tamer was very responsive and took time to understand the air conditioning issues and set very realistic expectations based on facts. Scheduling a visit was quick and easy, he arrived on time and did what was needed quickly while also being patient and took time to answer all questions and explained the details in relation to possible replacement of our old A/C and Furnace without trying to oversell us on anything. We would definitely recommend Tamas to everyone if you want someone who is clearly hardworking, wants to earn an honest living and win customers over the right way! Thank you Tamer and really appreciate your time and effort, you will definitely be our go to person for any heating/cooling issues.
I received excellent advice from Tamer regarding what power/BTU furnace I should choose. Prior to calling Tamas Mechanical, I had called several other companies, where I was getting conflicting and not clear advice on what BTU size I should choose. However, Tamer was clear on what BTU size I should choose and fair in the pricing. I was able to get advice on a Monday morning and order the unit by Tuesday and fortunately they accommodated me and had it installed two days later! The furnace is currently working well and keeping us warm and I also have a new humidifier April air 500 series that was also recommended and seems to be making the air in our house better. I will now be getting my ducts cleaned by Thomas mechanical and look forward to this service from them. I highly recommend this company.
We had Tamas come out due to a leak. He was professionally, timely and super friendly again this time. We are very satisfied with the work he did.Tamas is a great guy. Very friendly and informative. He installed a tankless water heater for us which has been working great. Also gave us a great price compared to what we were being quoted by others. Will definetly use his services in the future.
Tamer was quick to come diagnose our furnace and very knowledgeable on what the problem was. He took the time to answer our questions and listened to our concerns. He stayed in contact and updated us about when the part was going to be available and it was a quick turn around. He was very accessible and efficient. We would definitely recommend and use tamer again!
Tamas Mechanical were a pleasure to deal with. They replied promptly to my request, showed up within 12 hours and diagnosed the problem. Although the repair was beyond their scope, they were honest and upfront and recommended another company. I would use in the future if the need arises and recommend to others.
Tamer Sayer was the technician who came to service my furnace. I should preface my furnace is 14 years old and two other companies failed to fix the issue. Tamer spent over two hours diagnosing the issue and fixing it. Three weeks later furnace is still running like new. Al very grateful 🙏
