For new homes, additions or major renovations that need a central heating system.
Replace an aging or unreliable furnace with a system suited to your home's heating needs.
Consider higher-efficiency, two-stage or variable-speed options for improved comfort.
The right furnace isn't chosen by floor area alone. Your home's heating needs and existing setup can affect the equipment we recommend and the installation work required.
Heating load, insulation, windows and air leakage all matter when choosing furnace capacity.
Supply and return ducts must support the airflow needed by the new furnace.
Gas supply, venting, electrical connections and condensate drainage vary by installation.
AFUE, heating stages and blower type can affect energy use, noise and indoor comfort.
We'll visit your home to review its heating needs, ductwork and installation conditions, then explain suitable furnace options and provide a free installation quote before you decide.
Mas Air Home Comfort offers high-performance furnaces for every budget and heating need. From value-focused models to premium systems, each furnace delivers reliable, efficient, and quiet heating backed by advanced technology and rigorous quality standards.




You don't need to choose a furnace on your own.
Our team will help you select a furnace based on your home's heating needs, ductwork and installation setup.
We visit your home to review heating needs, the existing furnace (if any), ductwork and airflow, plus gas and venting conditions. We recommend a suitable system and provide a free installation quote before you decide.
Once you approve the quote, we remove the old furnace when needed, install the new unit and complete the approved ductwork, gas, venting, electrical and condensate connections.
We leak-test gas connections and complete the manufacturer's start-up checks, including ignition, airflow, temperature rise and thermostat operation. We then explain the controls and basic filter care.
The work depends on your existing heating setup and selected furnace. Any required changes will be explained in the installation quote before work begins.
We'll assess your home's heating setup, recommend a suitable furnace and explain the installation work and quote before you decide.

The cost depends on the furnace model, heating capacity, efficiency rating and the work needed in your home. Changes to ductwork, venting or gas connections may affect the final price. Mas Air offers a free on-site assessment and installation quote so you can review the costs before deciding.
A straightforward furnace replacement can often be completed in one day. If your home needs ductwork changes, new venting or other adjustments, installation may take longer. We’ll review the work involved and discuss the expected schedule before installation.
The right furnace size depends on your home’s heating needs, not just its square footage. Insulation, windows, layout and Toronto’s winter temperatures all matter. Mas Air can assess your home and help you choose a suitable furnace without simply matching the size of your old unit.
Often, yes. If your existing supply and return ducts can handle the airflow required by the new furnace, you may not need to replace them. Our team checks your ductwork and explains any changes needed before installation.
It depends on your budget and comfort goals. Two-stage heating can provide steadier temperatures, while a variable-speed blower can improve airflow control and help reduce operating noise. Mas Air can explain the differences between available Lennox models during your assessment.
A repair may make sense if your furnace is in good condition and the problem is limited to a replaceable part. Replacement may be worth considering if the furnace has frequent breakdowns, major component damage or high repair costs. Mas Air can inspect your system and explain both options before you decide.
