Furnace Tune Up in North York, ON

Plenty of North York bungalows have been raised, extended or rebuilt while keeping their original ductwork. A $150 tune-up each year checks that your furnace still copes with the larger house, and records the proof on a checklist.

Furnace Tune-Ups for North York's Changing Homes

When a house grows but the trunk duct stays the same, the furnace has to serve more rooms through the same ducts, and dust and heat build up faster. Our yearly visit cleans out that build-up, from the filter and burners to the drain lines, hoses and flame sensor, and measures the temperature rise so you know whether airflow is keeping up.

Cozy World is TSSA registered as a heating contractor, HRAI registered, gas licensed, insured and bonded, and our technicians come from our Toronto office with factory training. Where the visit points to a deeper fault, we can schedule North York furnace repair with the price settled in advance.

Every Point We Cover on a Tune-Up

Your technician completes all six checks and marks each one on the report, which also identifies the furnace by its model and serial number.

  • Filter

    A new filter is fitted, and we record the size so you can stock the right one.

    Without it: A dirty filter in an extended house leaves the far rooms cold and lets the furnace overheat.

    Air reaches the new rooms too.

  • Condensate hose, line and pump

    We clear the hose and the underground line with compressed air and confirm the pump empties properly.

    Without it: If condensate backs up, a high-efficiency furnace switches itself off to protect the house.

    Heat without interruptions.

  • Pressure switch hose and internal tubing

    We blow through the pressure switch hose and the rest of the furnace's small tubing.

    Without it: A pressure switch fed by a wet or blocked hose stops the furnace before it lights.

    Ignition on demand.

  • Flame sensor and burners

    Our technician cleans the sensor and the burner box and blows away the dust around them.

    Without it: Carbon on the sensor and dust on the burners lead to short, faltering flames.

    Clean, even combustion.

  • Intake vent and cabinet

    The intake connection is brushed clean and the furnace interior is vacuumed out.

    Without it: Grit collecting at the intake, plus dust inside the furnace, starves the burners of air and wears the parts.

    A furnace that breathes freely.

  • Temperature rise and flue gases

    We measure the supply and return temperatures and analyse the flue gases for carbon monoxide and carbon dioxide.

    Without it: In a house with too little airflow the temperature rise climbs, and poor combustion can raise carbon monoxide.

    Evidence of safe, balanced running.

Furnace Upkeep for Raised and Rebuilt Homes

Whether your bungalow has gained a second storey, a rear addition or a finished basement, a yearly tune-up keeps the furnace working within its limits.

A Call When It Is Time

Join the reminder list and expect a call from us each year when the tune-up is due, so the furnace is ready before the first cold night.

Cleaning and Readings for $150

The filter, burner box, flame sensor, drains and internal hoses are cleaned, and the combustion and temperature rise are measured, all for one price.

A Report You Can Compare

Keep each year's signed checklist and you can see whether the temperature rise or combustion figures are drifting as the house and furnace age.

The Steps of a North York Tune-Up

The tune-up follows six fixed stages and usually lasts from half an hour to an hour, with older furnaces often at the longer end.

  • Arrange the Visit

    Our Toronto office agrees a date with you before the heating season and gives you an arrival window.

  • Note What You Have

    We record the furnace's model, serial number and installation year, and ask about any additions or renovations to the house.

  • Clean the Main Parts

    We swap the filter, clean the burner box and flame sensor, and vacuum the dust from inside the cabinet.

  • Blow Out Every Line

    The drain hose, underground line and internal hoses are cleared with air, and we check that the pump carries water away.

  • Test Airflow and Combustion

    We measure the temperature rise across the furnace and the carbon monoxide and carbon dioxide in its flue gases.

  • Explain the Findings

    You get the signed checklist and a plain explanation of what the readings say about your furnace and your ductwork.

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.

Where We Service Furnaces Across North York

Much of Willowdale, Bathurst Manor and Downsview was built as 1950s bungalows and side-splits, and many have since gained a storey or an addition while the ducts stayed largely as they were. Don Mills, planned from the start, tends to have sensible duct layouts, while York Mills, Bayview Village and Armour Heights hold larger homes that put a big load on a single furnace. Each calls for a slightly different eye during a tune-up.

Tune-ups here are dispatched from our Toronto office, which also handles our full range of heating and cooling work in North York.
