Boiler Installation and Repair services

The Team That Knows Toronto Boilers

Boilers operate on gas, water and pressure simultaneously and therefore require a team with actual hands-on experience. We have been repairing and installing them since 2013, on cast iron radiators and modern combi units. Boiler repair is one of our many HVAC services, and if your home is heated by a furnace, we also offer furnace repair.

  • 24/7 boiler repair service: a licensed technician is there to help when the heat cuts out.
  • Licensed and insured team: safe boiler repair services with trained team for gas and hydronic systems.
  • Upfront and honest pricing: a clear quote before we start, with no hidden charges.
  • Old and new systems: we work on steam and hot water boilers, from decades-old units to high-efficiency models.
  • Every major brand: one team for the whole range of boilers in GTA homes.
  • Clean and respectful work: we clean after each visit and treat your home with care.
  • Same-day service: most boiler repairs get booked and finished the same day.

Why Boiler Work Calls for a Specialist

A boiler is a closed and pressurized system where water is heated by a gas flame. A simple mistake can be a serious hazard if the pressure, gas, or venting is not correct. A leaking relief valve or a cracked heat exchanger is not something to be solved with a hunch. Ontario law requires that this work be done by a licensed technician who is qualified in gas and hydronic heating. We identify safety concerns that would otherwise go unnoticed by an untrained eye and fix the problem correctly.

Signs Your Boiler Is Struggling

Typically, a boiler will warn of trouble long before it fails completely. If you notice these indicators early, you’ll be spared of a cold home and an expensive fix.

  • No heat, or radiators that remain cold.
  • Radiators warm at the bottom but cold at the top
  • Banging, gurgling, or rumbling from the boiler
  • Water pooling or dripping around the unit
  • Low pressure on the boiler gauge
  • The pilot or burner keeps shutting off
  • Rising gas bill over the winter months
  • Rooms that are extremely slow to heat.
  • No hot water from a combi boiler
  • Notice any of these? Schedule boiler repair before the cold weather sets in.

Trusted boiler repair services for homes, businesses, and industrial sites.

Boiler Breakdowns We See and Solve

Everest technicians can fix all types of boiler problems found in Toronto homes and businesses. These are the problems we see most frequently, and the typical reason for each.

  • Low water level: a leak or a failure of the expansion tank to maintain the gauge pressure.
  • Leaks around the boiler: worn seals, valves, or a corroded pump.
  • Kettling: limescale on the heat exchanger that causes banging and rumbling.
  • Air in the system: trapped air that causes radiators to be cold at the top.
  • Faulty circulator pump: pump that has stopped circulating hot water into the home.
  • Pilot or ignition failure: a flame that will not light or stay lit.
  • Damaged heat exchanger: age or corrosion that poses a carbon monoxide danger.
  • Pressure relief valve failure: safety valve that leaks or sticks.

Yearly Boiler Servicing That Heads Off Trouble

Most boiler problems begin as minor issues that can be identified in an annual service. We check the pressure, test the relief valve, inspect the heat exchanger, bleed the radiators, and look for leaks. A serviced boiler will operate more safely, last longer, and use less gas during the winter. Getting your boiler serviced and repaired in early fall ensures that your boiler is ready before the cold weather comes. Many manufacturer warranties are also extended with regular service.

When a New Boiler Makes More Sense

There are certain boilers that have hit a ceiling for repair. If you have a unit that is over fifteen or twenty years old, leaking or breaking down frequently, and your bills are increasing, it’s probably time to replace it. We help you select the right high-efficiency boiler size that fits your home so that it heats every room without wasting energy. Some homeowners switch to a heat pump instead, for one system that heats and cools. We take out the old boiler, install the new one to code, and run a full system test. Rebate programs can help reduce the price of a new high-efficiency boiler.

No Heat and Not Sure Where to Start?

There is no need to know the cause before calling. If the boiler is making noises, has no heat or hot water, or if it has leaked, let our technician know what is happening, and they will proceed from there. After determining the problem we can provide you with a simple explanation of your options and a clear quotation. You are in control of what happens from there, without any pressure and no jargon.

Emergency Boiler Repair When the Heat Goes Down

A boiler that breaks down during a deep freeze is an emergency, and a leak can wreak havoc in no time. Everest runs emergency boiler repair across the GTA, day and night, all winter. Give us a call, and a licensed boiler repair technician will be at your doorstep in no time to restore the heat. We have taken these urgent calls since 2013, so we work quickly and get it right the first time.

How We Handle Your Boiler Repair

All boiler repairs go through the following steps, so you can trust what happens next.

  • Diagnosis: We inspect the gas side, water side, and controls to determine the exact fault.
  • Repair: We fix or replace the faulty component with high-quality parts.
  • Test for safety: Pressure test, relief valve test, and venting test before signing off.
  • Advice and follow-up: we share simple tips to keep your boiler operational for the entire season.

What Boiler Repair Will Cost You

The price of repairing a boiler depends on the actual fault, the specific part and the age of your heating system. Replacing a valve or thermostat is cheaper than replacing the circulator pump and the heat exchanger. There is no hidden fee in the bill because we give you a quotation at the outset. Everest provides free quotations either through phone calls or emails, and the charges for each job are reasonable. We stay straight with you on price from the first call.

FAQs

  • 1. How much does boiler repair cost?

    It depends on the fault and the component. A simple repair will cost significantly less than a pump or heat exchanger repair. You will receive an estimate before any repairs are done, and there is no charge for estimates over the phone.

  • 2. Do you offer emergency boiler repair?

    Yes. We offer 24/7 boiler repair emergencies throughout the GTA during the winter. Call anytime, and a licensed technician heads your way.

  • 3. Why are my radiators cold at the top?

    Cold at the top of your radiators usually means trapped air in the system. Bleeding the radiators often fixes it. But if this occurs regularly, it can indicate problems with the pump or low pressure and will need a licensed professional.

  • 4. Why does my boiler keep losing pressure?

    The usual culprit is either a slow leak or a faulty expansion tank. A boiler should hold steady pressure. Should yours experience pressure loss repeatedly, book a technician to find the source.

  • 5. Do you repair steam and hot water boilers?

    Yes. Our licensed technicians repair all makes and models of steam and hot water boilers. We have provided heating services in the GTA since 2013.

Very disappointed with my experience. I was charged what I felt was an excessive amount just to be told my water tank had failed. No repair was completed, yet the bill was still very high.

When I questioned the charge, I was told I had “already received a deal” because I had previously used Everest Plumbing for a flood. That response was disappointing and didn’t justify the cost.

To make matters worse, during the previous job I had arranged for my property management to shut off the building’s main water supply for the scheduled work, but Everest Plumbing never showed up. It wasted everyone’s time and caused unnecessary inconvenience.

I won’t be using them again.

Big thanks to Mr. Nimesh. He really saved me and my home from almost flooding the basement. Nimesh was quick to snake the blocked drain, and later, with his camera inspection, he found that the blockage was caused by roots. He snaked and cleared out the roots. Everything is now working completely fine, and he showed his work through a camera inspection proving the roots were cleared after the snake. A big thank you to Mr. Nimesh for helping to calm down such a panic moment.

First time working with Everest. Great experience! Was able to get a next morning appointment to fix our leaking sink. Plumber arrived on time, analyzed the problem, replaced a part, cleaned out the drain, tested everything, and cleaned up. The price was reasonable. Our new go-to plumber when we need one (not too soon please😉) Highly recommended.

Found Everest on Google after looking for someone to clean our drain line. Rajiv and Sandip appear as a team; their housekeeping was excellent. They cover and protect every aspect as needed. The work performed was clean and swift. They did power flushing until all the debris was clear time and again. Impress with their dedication toward work.
Great team, will use them again in the future.

Great Drain Cleaning and Flushing Service by Tenzin and Mr. Sandip, who well-communicated and was professional about all the work he did. Housekeeping was top-notch, from bringing tools in to keeping tools properly while working.
Everything was smooth from beginning to finish. No mess; leave the house as it was after completing snaking and flushing.

Tenzin came to fix a sump pump and check valve issue after a massive rainstorm. He worked hard to diagnose the complex problems and trial a few different solutions that fit the unique aspects of my house and property. His demeanour was very kind and calm and it was a pleasure to have him in our house. Great work!

Excellent service from Everest Drain & Plumbing. They are a family-owned business and Indra arrived promptly for a service call on the weekend, even though he works weekdays, to fix my clogged drain. They were very efficient and courteous. Indra assessed the situation in a timely manner and fixed the issue quickly without making any mess. Definitely knows his work, and I highly recommend them if you're looking for a local plumber. Thanks, Indra. Great work!!!

I had a pipe burst a few days ago and contacted several companies, but Everest Drain and Plumbing was the only one that could clearly confirm how soon they could attend to the issue. They offered me a 9:00 AM appointment the following morning and arrived right on time — even a bit early.

I truly appreciated the prompt response, professionalism, and fair pricing. The service was efficient, and everything was handled smoothly.

I would definitely choose Everest again for any future plumbing needs.

Thank you, Everest, for your excellent and reliable service!

I had a pipe burst a few days before Christmas - tis the season. Out of the companies that I contacted, Everest was the only company that could confirm how soon they'd be able to attend to the issue. They offered an appointment for 9am the following morning and Indra was prompt, if not early.

We were very appreciative with his service, and I would go directly with them for future plumbing issues/needs.

Thank you Indra and Everest for your prompt service and pricing.

Our main drain was cracked. From the moment we called Everest Drain the service has been exceptional. Indra was very professional and honest, the work they performed was very clean as they had to dig a finished basement. They did not make a mess and finished the job on time. I have no hesitation in recommending this company.

I recently had the pleasure of working with Everest Drain & Plumbing in Toronto, and I could not be more impressed with their exceptional service! From the moment we called them for assistance with plumbing work, I knew it was in good hands. Aly was punctual, with something we always appreciate. Not only professional but also incredibly knowledgeable about the problem. He explained in detail and made me understand before moving forward. The work was completed with the highest level of craftsmanship. One of the standard aspects of Everest Drain & Plumbing is their fair and upfront pricing. The pricing was reasonable for the quality of work provided, and I appreciated their transparency. What truly sets them apart is their outstanding customer service. Aly made sure to clean up after all the work completed, and there were no surprises when the work was done. I was overall impressed by how well Aly managed the entire process from diagnosing to resolution. If you are looking for a trustworthy, skilled and professional Plumbing company look no further. They have earned a loyal customer in me!
