No Heat? Emergency Boiler Repair in Kitchener

A cold house in January can't wait until Monday. We take boiler no heat repair Kitchener calls day and night. If you searched 24/7 boiler repair near me, run through the four checks below first, because sometimes the fix is simple. If the heat still won't come on, call and we'll book boiler repair in Kitchener and talk you through what to do until the technician arrives.

Carbon monoxide alarm going off? Get out first.

Leave the house with everyone, including pets, and call 911 or your gas utility's emergency line from outside. Don't call a plumber first and don't go back in. Once responders say it's safe, we'll inspect the boiler and its venting.

Call 911

No CO alarm? Check these 4 things before you call

1

Thermostat

Make sure it's set to Heat and a few degrees above room temperature. If the screen is blank, replace the batteries.

2

Power Switch

Boilers have a service switch that looks like a light switch, usually near the unit or at the top of the basement stairs. Check that it's on and the breaker hasn't tripped.

3

Pressure Gauge

Most home boilers sit around 12–15 psi when cold. If the needle is near zero, the system is low on water. Don't top it up yourself if you're unsure how.

4

Error Code

Snap a photo of any code or blinking light on the display. You can press reset once. If it locks out again, stop and call us.

Checked everything and still no heat? Call now. We answer 24/7.

Warning Signs

Boiler Not Heating? Signs You Need a Repair

Boilers usually give warning signs before they quit completely. If you notice any of these, book boiler repair in Kitchener before a small fault turns into a mid-winter breakdown. Whether you searched boiler repair near me or gas boiler repair near me, we'll find the cause and explain your options before any work starts.

Boiler Repair and Installation in Kitchener

From a quick fix to a full system swap, our boiler repair Kitchener team handles every part of a hot water heating system: the boiler, the pumps and valves, and the loops that carry heat through your home.

Boiler Repair

Cold radiators, lockouts, leaks or a pump that won't run? We track down the fault and fix it, often in a single visit when the part is on hand. Searching boiler repair near me on a cold night? We answer 24/7.

  • Combi, condensing and standard boilers
  • Pumps, valves, igniters and controls
  • 24/7 no-heat calls

Boiler Installation

Our boiler installation Kitchener service starts with sizing the boiler to your home, not guessing from the old unit. We handle the venting, piping and controls, then start it up and show you how everything works.

  • Sized to your home's heat loss
  • Combi, condensing and system boilers
  • Start-up check and walkthrough

Boiler Replacement

When an old boiler costs more to keep running than to replace, we remove it and fit an efficient new unit sized for your home.

Annual Service

A yearly tune-up keeps the boiler safe, efficient and less likely to fail in January. Searching boiler service near me? Book before the heating season.

Hydronic Repair

Radiators, baseboard heaters and radiant floor loops, plus the circulator pumps and zone valves that move heat to each room.

Combi Boilers

One compact, wall-mounted unit for both heat and on-demand hot water. A good fit for smaller Kitchener homes short on basement space.

Boiler Repair or Boiler Replacement?

Not every breakdown means a new boiler, and not every old boiler is worth fixing. This is the checklist we go through before recommending one or the other.

VS

Repair makes sense when…

The boiler is sound and the fault is fixable

  • The boiler is under 15 years old

  • It's a one-off fault: a pump, igniter, valve or sensor

  • Replacement parts are still available

  • The house heats evenly once it's running

  • No water is leaking from the boiler body itself

Replace makes sense when…

Most boiler replacement Kitchener calls we get start with one of these

  • The boiler is 15–20 years old or more

  • It breaks down every heating season

  • Gas bills keep rising with no change in how you use it

  • The heat exchanger is cracked or the boiler itself is leaking

  • Parts are discontinued or hard to find

Searching boiler replacement near me but not sure you need one? We'll inspect the boiler first and give you a straight answer. If replacement is the right call, our boiler installation in Kitchener covers sizing, venting and start-up.

Choosing a New Boiler

Combi, Condensing or System Boiler?

The right boiler depends on the size of your home, how much hot water you use and the space you have. Before any boiler installation in Kitchener, we look at all three. If you're comparing options for a new boiler installation near me, here's how the main types differ.

High-efficiency condensing boiler installed in a Kitchener basement High Efficiency

Condensing Boiler

Condensing boilers capture heat from their own exhaust that older models send up the chimney. Searching condensing boiler installation near me? Most new combi and system boilers are condensing too, so you get the efficiency either way.

Best for: replacing an old, inefficient boiler and cutting gas use

  • Efficiency of 90% AFUE or higher
  • Vents through a side wall with PVC pipe
  • Works with radiators and radiant floors

Combi Boiler

Best for: small to mid-size homes with one or two bathrooms

  • Frees up basement floor space
  • Endless hot water, no tank to run out
  • One appliance to service instead of two

Hydronic and Radiant Floor Heating Repair

Hot water heating doesn't stop at the boiler. Cold patches on the floor, noisy pipes or one zone that never warms up usually point to the pumps, valves or loops that carry the heat. Our hydronic heating repair covers the whole system, so boiler repair in Kitchener and the loops it feeds are handled by one team.

Cold spots on the floor

Uneven heat in one room or zone, often from trapped air or a stuck valve.

Air in the system

Gurgling pipes and half-cold radiators. We purge the loops and fix where the air gets in.

Pumps & zone valves

A failed circulator or a stuck zone valve keeps heat from reaching part of the house.

Loop flushing

Sludge and scale build up over the years. Flushing the loops restores flow and even heat.

Need radiant floor heating repair or hot water boiler repair near me? Tell us which rooms are cold and we'll trace the problem from the boiler to the floor.

Boiler Repair & Installation Reviews in Kitchener

Experiences with emergency boiler repairs, heating problems, boiler replacements and new hydronic heating installations in Kitchener homes.

★★★★★

"Our boiler stopped heating the house on a freezing January evening. The radiators were getting cold and we couldn't get the system to restart. NeoDrain came out, checked the controls and found a faulty circulation pump. They replaced it and made sure hot water was moving through the radiators again. Very relieved we didn't have to spend the night without heat."

Callum Fraser

January 19, 2026

★★★★★

"The boiler was running, but two radiators upstairs barely warmed up. We kept turning the thermostat higher without much improvement. The technician checked the heating loop, removed trapped air and corrected a circulation issue. The rooms heat much more evenly now. Appreciated that he explained what was happening instead of suggesting a new boiler."

Anouk Tremblay

February 12, 2026

★★★★★

"Our old gas boiler had become unreliable and needed repairs almost every winter. We decided to replace it with a modern high-efficiency unit. The team explained the sizing, venting and installation requirements before starting. The new boiler takes up less room, runs quietly and keeps the house comfortable. The installation was organized and the utility room was left tidy."

Evander Whitmore

March 6, 2026

★★★★★

"The pressure gauge on our boiler kept dropping, and we had to top up the system more often than usual. I was worried there might be a leak somewhere under the floors. NeoDrain checked the expansion tank and found it wasn't maintaining pressure properly. They fixed the issue, tested the system and showed me what pressure range to watch for."

Seraphina Nowak

April 22, 2026

★★★★★

"We noticed a small puddle underneath the boiler in our basement. It wasn't a lot of water, but it kept coming back. The plumber traced the leak to a worn connection on the heating return line. He replaced the fitting, checked the surrounding pipework and tested the boiler afterward. Everything has stayed dry, and there was no pressure to replace the whole system."

Lucien Bellerose

September 17, 2026

★★★★★

"We had a combi boiler installed while updating the heating system in our older home. There wasn't much space in the utility room, so getting the layout right mattered. The technicians installed the new unit, connected the heating and domestic hot water lines, and walked us through the controls. The system has been working well, and we're happy with the extra space."

FAQ

Boiler Repair Kitchener: FAQ

Straight answers to the questions homeowners ask us most about repairs, new boilers and yearly service.

Still have a question?

Call and talk to a technician, day or night.

(226) 639-6783

My boiler is not heating. What should I check first?

Check that the thermostat is set to Heat, the boiler's service switch and breaker are on, and the pressure gauge isn't near zero. Note any error code and try one reset. If the boiler still won't fire or locks out again, stop there and call. If you're searching boiler repair near me late at night, we answer 24/7. If a CO alarm is sounding, leave the house and call 911 first.

Are your technicians TSSA licensed?

Yes. In Ontario, work on gas boilers must be done by a gas technician registered with the TSSA. Our technicians are TSSA-certified gas technicians, so repairs, installs and annual service on gas boilers are done to code.

How often does a boiler need service?

Once a year. Most manufacturers require annual maintenance to keep the warranty valid, and a yearly check catches worn parts and venting problems before winter. For boiler service in Kitchener, September and October are the best months to book, before the heating season gets busy.

Is a combi boiler right for my home?

A combi is usually a great fit for small to mid-size homes with one or two bathrooms. It heats the house and your tap water on demand, so there's no separate tank. Larger homes where several showers run at once are often better served by a system boiler with an indirect tank. Before any boiler installation Kitchener homeowners book with us, we look at your hot water use and recommend the right setup.

How long does a boiler last?

Most modern boilers last around 15 to 20 years with regular service, and older cast-iron units can go longer. Water quality, how well the system was installed and whether it's been maintained every year all make a big difference.

How long does boiler installation take?

A straightforward replacement usually takes one to two days. Switching to a combi, moving the boiler or adding new venting can take longer. If you're comparing quotes for boiler installation near me, we'll give you a clear timeline after we see the space.

Do you repair radiant floor heating?

Yes. We work on the boiler, the manifold, circulator pumps, zone valves and the loops themselves. Cold spots, slow warm-up and noisy pipes are usually caused by trapped air, a failed pump or sludge in the loops, and all of them can be fixed without tearing up the floor.

Do you work on propane or oil boilers?

Yes. If you're searching propane boiler repair near me or oil boiler repair near me, we service both. We also handle propane boiler installation in Kitchener homes without a natural gas line, and oil to propane boiler conversion when an old oil system is ready to go.
