Thorough Furnace Repair Across North York

Many 1950s bungalows in North York have been raised, extended or rebuilt, often without anyone reworking the ductwork that serves them. When a furnace in a home like that overheats, short cycles or leaves the newer rooms cold, we trace the airflow through the whole house before suggesting a repair.

Each technician we send has factory training, and the firm they work for holds HRAI registration, a gas licence, TSSA registration as a heating contractor, insurance and bonding. Should your furnace have aged past the point where repairs pay for themselves, we will be upfront about it and can quote for furnace installation in North York.

Furnace Symptoms and What They Mean

When you call, tell us whether the furnace is making a noise, leaking or refusing to stay lit. The more we know, the better prepared our technician will be for the likely cause.

The complaint What normally causes it How we approach it Done in one visit
The burner catches, then goes out again A flame sensor fouled by residue or worn out, and now and then a weak ground or low incoming gas pressure. Restore the sensor with a light cleaning or swap in a new one, then watch the burner through repeated starts. Yes
Heat is requested but the furnace stays silent Power turned off at the furnace switch or breaker, a thermostat or loose wire interrupting the call, or a dead control board. Work from the power supply and thermostat through to the control board, confirming each stage before replacing anything. Usually
Short bursts of heat that stop and restart Overheating because the return air never grew with the house, a filter packed with dust, a flame sensor losing its signal, or the thermostat's location. Check the filter, the return path and the temperature rise across the furnace, then deal with the cause. Varies
A wet patch spreading from under the furnace Condensate with nowhere to go, usually because the trap or drain line has clogged or the pump has quit. Clean out the trap and drain line, check that the pump runs, and fit a new pump if it does not. Usually
Loud bangs, squeals or rattles as it runs Dirty burners delaying ignition, a blower motor with tired bearings or a belt that slips, or loose sheet-metal panels or a blower wheel rattling. Pinpoint where the sound starts, then clean the burners, tighten what is loose or replace the worn part. Varies
The addition or upper floor never warms up Rooms added onto a duct system laid out for the original, smaller house, leaving too little supply and return air. Measure airflow at the registers, check the blower speed and return path, and explain your options before any work. Varies

Heating Repairs for Every North York Home

We repair furnaces that have stopped completely, systems that leave upstairs rooms cold, and the thermostats and zone controls that decide where your heat goes.

Urgent No-Heat Repairs

When the house is losing warmth during a cold snap, we treat the call as urgent. Through the heating season we are usually able to send a technician that same day, with the most commonly needed parts on board.

Care for Older Furnaces

With the right attention, an older furnace can often run safely for a while longer. We inspect the heat exchanger, venting and safety controls, replace worn parts and tell you honestly how much life it has left.

Thermostat and Zone Control Repairs

In an extended home, a single thermostat on the main floor or a stuck zone damper can leave some rooms too warm and others cold. We test the controls and wiring, then explain what will balance the heat across your floors.

Reviews You Can Read Before You Call

Before you invite a heating company down to your furnace, it is sensible to find out how it has treated other households. Over the years, homeowners have given Cozy World hundreds of five-star ratings across Google, HomeStars and Lennox.

HomeStars lists us as a Verified contractor, and the Better Business Bureau rates us A+, a grade we hold with no complaints ever filed against us. We have looked after furnaces since 1991.

I am very happy with the service I received from Cozy World. My inquiry was responded to very quickly by the reception and Fred came to my house twice. First to look at my set up and again to answer a few more questions before I asked them to go ahead with the purchase and installation. He helped me determine what would be the best solution for my house. The installers (Said and his helper) were friendly, thorough and answered all my questions and gave me advice for the future.

This was our first time working with Cozy World and would definitely recommend them. The pricing was very reasonable and they were able to schedule a rush replacement for our old furnace that died. Saeed did a fantastic job on the installation - very knowledgeable and professional.

Cozy World replaced our furnace and hot water heater and did an excellent job. Their quote was the best price we got, and the customer service was also excellent. Both the owner and the lead installer were very helpful and responsive.

I have used Cozy World Inc for the last few years for both service for a furnace not heating and for several installation (tankless water heater, new furnace and new AC). They have been very responsive, have fair pricing and go above and beyond to provide the best service. I would highly recommend them for your HVAC needs.

This was our first time working with Cozy World and I will definitely be a repeat customer again. They had done previous work at my parents place and for my sister, who both gave rave review. Boris was our first contact who sent his team on the same day to fix our furnace. Sayid was on-site and was kind, respectful and communicative about the work that needed to be done, not to mention timely. I felt like I was in good hands with this entire team, and highly recommend them.

Cozy world provided us with great service to replace a 13-year-old natural gas tank water heater that had stopped working. Fred was a pleasure to deal with from my initial call to the final installation. He suggested we go with a high efficiency tankless Rinnai unit that save on gas and takes up less space in the furnace room. His installers showed up as promised next day and completed the job quickly. I would recommend Cozy World Inc. for any of your HVAC need and I would not hesitate to contact them in the future. Great Service.

I had a 17 year old furnace that broke down in the middle of winter. Cozy world team made the quote to purchase and installation a seamless experience. The installation process was a breeze and was done in 2 hours time without any hiccups and surprise costs that other vendors hold. Big shout out to Cecilia and Farhad (Aka Fred) for quick response and providing the right guidance on the installation, warranty and support concerns.

What You Can Expect From Our Furnace Repair Team

You should come away from a furnace repair feeling informed as well as warm. We explain every finding in plain language, look after your home while we work and hold to the price we give you.

Familiar With Raised and Rebuilt Bungalows

We regularly work in raised and extended North York bungalows and in Don Mills homes with finished basements, so we weigh how those changes affect your heating before repairing anything.

Honest Advice on Repair Versus Replacement

You see the worn or broken part and hear why it failed, and if your furnace has few good years left, we set a replacement quote next to the repair price.

Respect for Your Home

We treat your home with care, keep the area by your furnace neat and put what we found and fixed in writing before we leave.

Credentials We Invite You to Check

Before we start, you can confirm our standing as a TSSA registered heating contractor that is HRAI registered, gas licensed, insured and bonded.

A Price Settled Before We Start

Once the fault is found, we quote a fixed price that you can accept or decline, and your invoice shows that same amount when the work is done.

What Happens During Your Visit

From your first call to the final test run, we follow the same clear order on every visit, so you always know where things stand.

  • Tell Us What You Are Noticing

    On the phone we ask you to describe the symptoms, when they began and whether the house has been extended or had its basement finished.

  • Check Every Part of the Furnace

    Our technician watches a full start-up, then checks gas pressure, the igniter and flame sensor, the venting and every safety switch before examining the heat exchanger.

  • Walk You Through the Findings

    Beside the furnace, our technician explains in everyday terms what has gone wrong, why it happened and whether anything else needs attention, especially where safety is concerned.

  • Approve a Fixed Price

    We start only after you approve a firm price for the repair, and when a new furnace is worth considering we cost that option as well, leaving the decision with you.

  • Carry Out the Repair With Care

    We install the new parts, check any gas joint we opened for leaks and tune the burners. Common parts come with us, which lets us finish most repairs in one visit.

  • Test, Tidy and Report

    We watch the furnace complete a few full heating cycles, tidy up around the unit and leave you a written record of the visit, including any parts we replaced.

Answers to Common Furnace Questions

Where We Repair Furnaces in North York

In North York, many of the furnaces we repair heat homes that have grown well beyond their original size. Across Willowdale, Bathurst Manor and Downsview, 1950s bungalows and side-splits have often been raised or rebuilt while keeping the original trunk duct. Don Mills, laid out as a planned community, tends to have sensible ductwork, although a finished basement or attic conversion can add rooms the original system was not planned to serve.

We cover the district from our Toronto office, reaching York Mills and Armour Heights as readily as Parkwoods and Newtonbrook, and the same technicians handle our wider HVAC services in North York.
