Attic Insulation ↗

40% of energy loss occurs through the attic. Inadequate insulation in older homes leads to significant temperature variations between floors and can cause issues like ice dams and roof mold.

Proper attic insulation optimizes temperature differences between floors, reducing bills and enhancing comfort.

There are two main types of Canadian attic insulation materials.

Fiberglass material

Made of about 70% recyclable silicone material, through ultra-high temperature melting and sterilization to make fibre yarn, and then made into cotton state insulation material. This material is non-toxic and harmless to humans and passed the highest safety standards in North America. Some companies on the market will use relatively low-quality white fibreglass for construction to reduce the company’s costs.

High-quality pink insulation Owens Corning® is currently the highest fibreglass standard in North America. This is also the material we have been using, as we have always upheld the construction quality and material measures to the extreme.

Recyclable cellulose insulation

This type of insulation is when the recycled paper products are shredded and mixed with fire retardant sprayed into the attic to achieve the insulation effect. Because the attic is hotter in the summer and has a circuit winding complex, this kind of insulation cotton material is straightforward to burn and may produce irreversible fires, despite a fire retardant added. As professionals, we believe that all people will not risk the 1% possibility of their lives and property being burned down. Many small factories mainly produce this kind of insulation material, and the quality level is uneven; the price cost is also significantly lower than the pink glass fibre cotton. Another fact is that the flame retardant may cause severe injury and damage to the respiratory tract. It is not a recommended insulation material.

Basement wall insulation ↗

Many new homes only have the upper half of the basement insulated, as required by government regulations. Contractors often meet only the minimum standards to cut costs, leaving the lower half uninsulated. This can lead to moisture penetration and discomfort in the basement during winter, along with potential mold growth due to indoor humidity.

Proper wall insulation is crucial for maintaining a comfortable basement. We offer professional basement insulation services to ensure a solid foundation before renovation. 

Mas Air Home Comfort’s team can install or upgrade attic and basement wall insulation, improving energy efficiency, reducing utility bills, and extending equipment lifespan. This investment also increases home value.

Garage insulation ↗

A cold, uninsulated garage doesn’t just affect your car — it drives up heating costs and makes the rooms above or beside it uncomfortable all winter long. Our licensed technicians insulate garage walls, ceilings, and rim joists for both attached and detached garages across the GTA.

Attached garages in particular are a hidden weak point in many GTA homes. Without proper insulation and air sealing, cold air and moisture migrate directly into your living space through shared walls and floors — making your heating system work harder than it needs to. Addressing this early is one of the most cost-effective upgrades a homeowner can make before winter.

Every garage is different, which is why we start with a thorough on-site assessment before recommending a solution. From spray foam on rim joists to blown-in insulation for ceilings, our technicians match the right material and approach to your specific layout, budget, and long-term comfort goals. Request a free estimate and we’ll take care of the rest.

Exterior Wall Insulation

High-quality exterior wall insulation provides excellent thermal performance, creating a comfortable living environment while reducing energy consumption — especially during Toronto’s cold winters and hot summers. Proper wall insulation effectively minimizes heat transfer, significantly improving indoor comfort while lowering energy loss.

Mas Air Home Comfort has extensive professional experience in both retrofit insulation for older homes and insulation installation for new construction projects.

By choosing us to upgrade your home with higher-standard exterior wall insulation, homeowners may be eligible for energy rebates of up to several thousand dollars. Most general renovation contractors do not have the specialized expertise or qualifications required to access and process these incentive programs.

Why Insulate Your Home

Insulating your home reduces energy loss by reducing the penetration of indoor and outdoor temperatures into each other. It will give you the comfort of a warm winter and a fantastic summer. In the long run, having a well-insulated home can effectively reduce equipment consumption for heating and cooling and improve the comfort level significantly.

The specific advantages of house insulation are as follows:

Optimize floors temperature difference

Poorly insulated homes can cause severe temperature disparities on different floors, especially in winter and summer. During winter, having proper insulation will keep the higher feet warm and the higher cold during summer. Insulating your home helps keep your home at an appropriate overall temperature, making your stay more comfortable while effectively reducing energy consumption.

Noise reduction

Home insulation has a high SPF, which reduces the amount of outside noise entering your home. It means that the insulation will be reducing the noise pollution you experience during stormy weather, certain loud holidays of the year, and especially near the road. The insulation will keep your home a relatively quiet environment.

Save energy costs

Good house insulation can help you save a lot of energy costs in the long run. Our insulation will block the heat from entering during summer and keep the heat trapped inside during winter. It will reduce the amount of activity from your heating and air conditioning equipment, which in turn saves you money.

Extend the life of your roof

Replacing and repairing roofing and roof shingles can be expensive and complicated. Insulating your home prevents condensation from forming in your attic shingles and prevents irreversible damage to the wood due to moisture and mould whenever possible.

Pest and wildlife prevention

Pest and wildlife droppings, food and carcasses can cause many health, noise, and economic damage problems. Insulating your home minimizes the risk of pests and wildlife nesting in your home and reduces the risk of damage to your home.

Qualify for government energy rebates

Ontario has implemented mandatory building insulation standards since 1990, with requirements continually increasing to meet rising homeowner expectations for energy efficiency.

Attic insulation requirements have progressively increased from R32 in 1990 to R60 in recent years. This means homes built before 1990 may have little to no attic insulation. Homes built before 2013 not only had lower mandated standards (below R60), but their insulation has often been compromised over decades through ownership changes, attic renovations, and pot light installations.

As a result, homes built before 2013 are eligible for substantial government energy rebates when upgrading their attic insulation.

💡 How to Get Your Rebate: Two Easy Ways

  • Single Upgrade：
    Ideal for targeting a specific energy leak in your home. For example, upgrading your Attic Insulation offers the best bang for your buck (ROI). You only need one eligible upgrade to qualify. Best of all? No pre-upgrade Energy Audit is required, meaning faster installation and quicker cash back in your pocket.
  • Bundle Upgrade：
    The ultimate way to unlock top-tier government grants. Bundle your insulation with a high-efficiency Cold Climate Heat Pump or a Water Heater. While this route requires a registered Energy Audit, it dramatically slashes your monthly utility bills and qualifies you for the maximum bundled rebate package.


Not sure which path makes the most sense for your home?
Skip the red tape and confusing government websites. The Mas Air rebate experts will assess your home’s needs and your budget to build a tailored, high-ROI upgrade plan. We handle the heavy lifting so you can just enjoy the savings.

The most honest HVAC company in the GTA!

Jack came over, was able to offer a reasonable solution to my home temperature issues.
When on site, realized that half of the job was not necessary. Let me know and didn’t charge me for needless work.

After the adjustment, I had overpaid - MAS refunded the difference on their own initiative.
David H Toronto
I recently installed heating, air conditioning, a water heater, and a water softener, all thanks to the recommendations from sales representative Shawn.

He was extremely professional and provided fair pricing tailored to my house.

Shawn promptly addressed any questions I had before and after installation.
Miranda Z North York
My furnace stopped working in a Sat morning, then I start looking for solutions.

My friend refered Norman to me and he came to check for me 2 hours later found out that the heat exchanger was gone.

Very fast response and great service, thumbs up! Will definitely recommend Norman to my friends
Jackie C Richmond Hill
We want to replace our water tank to an energy saving tankless water heater and sought assistance from this company. Shawn, our advisor, was exceptionally patient and thorough. He took the time to explain all possible options and detail with us, ensuring he fully understood our needs and preferences as customers. When it came time for the installation, David, the technician, was incredibly professional. He arrived promptly, worked efficiently, and maintained a high level of cleanliness throughout the process. His attention to detail and meticulous approach ensured everything was installed perfectly. I have nothing but good things to say. 
Cherry P Scarborough
Very happy with their service. Our furnace broke down on the weekend, and they booked to come the next day for a replacement.
The rep (Shawn) on the phone was very knowledgeable. His quote was a good price and it came with labour cost all inclusive, so no hidden fees.
When they got here, the technicians are highly skilled, hard working, and took the time to explain and answer our many questions. I am recommending these guys to my friends.
