A boiler failure in January isn’t only uncomfortable, it’s also extremely problematic. It’s a liability. Tenants complain. Staff can’t work. Pipes freeze. Every minute that you delay will come at a cost.
For over 2 decades BOS Plumbing Company and Drains has been repairing, servicing and installing commercial boilers throughout the GTA.
We know these systems like most people know how to get to work, by feeling them out, by listening to them, by knowing what’s normal and what’s not. Call us if you require a commercial boiler service near me in Mississauga, Oakville, Hamilton, Milton, Niagara or Cambridge – we arrive the same day and solve the problem right away.
Boiler services are NOT a ‘walking around inspection’. When our techs come into your home, they’re performing a complete inspection and tuning and not a clip board exercise.
What’s included in every commercial boiler service:
All major brands of commercial boilers are serviced including: Viessmann, Weil-McLain, Burnham, Lochinvar, Navien, IBC, Crown and more. Gas, oil or combination units.
Expert solutions for all your residential & commercial plumbing needs
We serve the Greater Toronto Area and surrounding regions with local expertise
BOS Plumbing and Drains provides all types of Commercial and Residential Boiler Services in the Greater Toronto Area. Our Engineers are trained on legacy systems as well as high efficiency systems.
We service and install:
If you’re looking for a routine boiler service, emergency boiler repair or a complete new boiler installation near you, we can service all the boiler systems found in office buildings, restaurants, apartment complexes and commercial facilities in Mississauga, Oakville, Hamilton, Milton, Niagara and Cambridge.
Some contractors are trying to promote replacement after the repair. Others repair a system that it was necessary to replace two seasons ago. We have the straight story!
If the problem is localized and your boiler is less than 15 years old, then a failed circulator or a malfunctioning gas valve, or a heat exchanger crack repair will likely be worthwhile. The most frequently used commercial parts are kept in our service vehicles and we can repair most of the problems the same day. We’re the plumbing company that shows up ready when you need a quick job done, such as a boiler repair near you.
If the unit has been around longer, it’s less efficient and you start getting recurring problems, we’ll explain your new boiler replacement options to you. We fit combi boiler installations, combination boiler systems and regular hot water boilers, to the actual heat load of your building, rather than what fits on a truck.
No pressure. Real numbers. You decide.
When a major boiler failure occurs, most commercial systems will give you some indication, like warning signs. These problems can be prevented from becoming more serious if they are found early.
If you see the following, give BOS Plumbing and Drains a call:
If you’re experiencing any of these symptoms, it’s best to have a boiler service near me in the early season to avoid a complete shutdown later on.
There’s more to installing a new commercial boiler than meets the eye. It’s not all about the equipment. You also require the correct sizing, venting, coding compliant gas connections and the correct plumbing balance in each zone.
BOS covers all of the above:

Looking for a combi boiler installation near me or a licensed combi boiler installation team for a complete combination boiler installation, BOS is available to provide a quote.
This is our 20th year in business in this market. It’s not a marketing statement, it’s the truth, for the reasons that we’re getting referrals from property managers who have previously tried 3 other contractors.
We are a complete plumbing company and HVAC services provider and our knowledge of boilers is just one of our skills that we apply to every job. Our licensed gas fitters and plumbers know how heating and cooling systems, plumbing and building operations relate – it’s reflected in the work.
Some things that make a difference to commercial clients:
We Show Up: It seems simple enough. It isn’t. Our schedule is true and our techs are on time! If there are changes made, we call.
We Document Everything: following each service visit, a written record is provided. It’s good for your records, it’s good for insurance purposes and it’s good if the next tech comes by and wants the unit for a service call.
We Work Around Your Tenants: Commercial properties don’t always allow a complete shutdown of the system during business hours. We organise around your schedule.
We’re Licensed And Insured: All of our technicians are licensed Gas fitters in Ontario and are insured. Our work fulfils TSSA standards. We do all of the permits if they are required for your municipality.

Regularly work with:
We have installed a wide range of heating systems from legacy boilers in Hamilton industrial buildings, to even newer high efficiency heating systems in Milton commercial developments, over the course of 20+ years in the industry.
Patterns emerge after 20 years of the commercial boiler business. These are the most common calls we receive:
No Heat At One Zone: Most likely the zone valve is stuck open or the circulator pump is not working. Usually can be resolved on the day of the incident.
Boiler Keeps Shutting Off: Condensate traps are clogged, pressure relief valves are malfunctioning or water level is low and resulting in a safety cutout. It is not diagnosed on a guess and check basis.
Strange Noises Banging, Kettling, Gurgling: Kettling is generally an indicator of limescale or flow. If there is banging in a steam system it is likely that water is accumulating in places it shouldn’t. Both are diagnosable.
Pilot Will Not Stay Lit / Ignition Failure: Gas valve, thermocouple or ignition board. Common parts are available for purchase.
Repeatedly Losing Pressure In The Boiler: A leak is present in the system or around the pressure relief valve or in the expansion tank. We found it.
Yellow Or Orange Flame: Combustion problem and a carbon monoxide hazard. Call us immediately.
The most costly boiler service is an emergency one that occurs at 11pm in February.
Our annual maintenance contracts for commercial buildings are designed to thwart that. Auto-tune-up performed in the fall and a system check during the season when needed, and priority emergency response when required.
Multiple buildings are scheduled and managed in one place, with a single contact for the property manager. A headache-free way to coordinate, and more peace of mind.
Talk to us about the costs of a maintenance plan.
No surprise invoices. No upsells you didn’t ask for.

What makes clients stay with BOS:
The boiler service near me, boiler fitters near me, and trusted plumbers GTA want a company that arrives on time, provides clear communication and gets the job done right the first time.
Central air conditioner installation on a home with existing ductwork is typically completed in one day. Mini split installation for a single zone takes 3–5 hours. Multi-zone ductless ac installation may require a full day depending on the number of indoor units and complexity of line set routing.
For most central air conditioner installation work involving electrical connections, a permit is required. BOS manages permit requirements as part of our service, keeping you fully code-compliant without the administrative headache.
Home depot ac installation services are typically coordinated through third-party subcontractors. BOS is a direct-service, licensed HVAC and plumbing company with 20+ years of GTA experience and full accountability for every job. You work with us from quote to completion.
Mini splits AC don’t require ductwork and allow room-level temperature control. Central air conditioner installation delivers whole-home cooling through existing ducts from a single system. The right choice depends on your home’s layout, existing infrastructure, and how you want to manage cooling across different spaces.
Sometimes, system components need to be matched properly for efficiency and reliability. Our technicians will assess compatibility between existing indoor components and a new outdoor unit before recommending partial versus full system replacement.
We cover our installations with a workmanship warranty. If an issue develops that’s related to the installation, we return and resolve it at no charge. Call us directly, no third-party warranty service centres, no runaround.
