Our Boiler Replacement Services

Boilers are one of the most comfortable and efficient ways to heat your home or business. Whether combined with radiators or infloor heating, the heat they produce is much less drying than the heat from a standard gas furnace.

When combined with infloor heating, boilers provide warmth where it’s needed most: at foot level. Because heat rises, it is gently distributed throughout your home. Many customers find they don’t need additional heating on the second floor.

We also provide boilers that can power snow melt systems for your driveway, walkways or even a patio. Imagine the freedom of never having to lift a snow shovel again.

Our Favourite Boiler Brand: NTI

NTI Boilers logo

We love NTI boilers because they’re efficient, and our customers love them because they’re reliable.

NTI boilers are made with an advanced heat exchanger with better flow through – that means better energy efficiency and less money spent on energy every month.

They’re also easier to access to clean and service. The modern display system also means that in rare cases when something does go wrong, troubleshooting and repair takes much less time.

Oil to Gas Conversions – Save up to 50% in Energy Costs

ATEL Air has the expertise to remove costly and unsightly oil tank systems, and replace them with a gas boiler that’s not only more efficient, but that leaves more space in your basement too.

Quality Boiler Installations: the ATEL Air Difference

To get the most out of your new boiler, the most important thing is to ensure you get the installation done properly. The gas line and plumbing setup has to be done correctly, or else you’re setting yourself up for frequent repairs. Some homes will need a water softening system to ensure hard water scale doesn’t build up, reducing efficiency and even causing parts to fail.

At ATEL Air, we believe so strongly in our expertise that we offer a 100% Satisfaction Guarantee. If your system doesn’t work as promised or requires repair, we’ll fix it for free. If it fails repeatedly, we will even replace it with a comparable system for free.
