London's Trusted Furnace Installation and Repair Experts

Think of your furnace as the heart of your home. In the winter, it radiates warmth to your living spaces. During the summer, it plays a vital role in circulating refreshing, conditioned air from your cooling system. And all year long, your furnace can provide consistent air circulation to keep you more comfortable. Not only that, but our ENERGY STAR® qualified models do it all so efficiently your own heart might skip a beat when you see how low your utility bill is.

Today’s forced-air furnaces are available in single-stage, two-stage or multi-stage models. Think of heating stages as gears on a bicycle or a car. Single-stage models are like a bicycle with one gear. It’s great on a flat stretch of road, but takes a lot more energy to go up a steep hill. Two-stage models add a second gear, one to handle everyday heating needs, and a second gear to provide additional heating as needed. Multi-stage or modulating stage furnaces are like cruise control on your car, adjusting up and down as needed to provide comfort and efficiency as weather conditions change.


You can compare furnace efficiency among models from different manufacturers using the AFUE rating -- the higher the AFUE, the better the efficiency. Current high efficiency furnaces can be rated up to 98.5% AFUE, which can reduce utility costs over the life of the furnace. In many cases, our Carrier high efficiency furnaces also include technology that can produce enhanced comfort benefits and quieter operation as well.


When you turn to the Carrier experts at Zed-Air Heating and Air Conditioning for your home heating system needs, you’ll find a comprehensive selection of furnaces designed to fit any home and nearly any budget. Of course, the cost of a new furnace often reflects the comfort benefits, performance and length of warranties.


Some things to consider when purchasing a new furnace:

Has your home been warm enough in the winter?

How long do you intend to keep your house?

Do you see yourself enjoying your system for years, or are you upgrading your system to increase the resale value of your home?

Have you considered investing more money in your equipment now to save money in long-term energy costs?

Are you looking to save on your up-front equipment costs?

How important is air quality to you?

Does anyone at home suffer from asthma, allergies?

Do you have pets in your home?

Does anyone suffer from dry itchy skin in the winter?

Is controlling the humidity something you have considered?

Furnace Installations

Zed Air is the best choice for your furnace installation. All our installers are licenced! Even the best furnace won’t perform the way it was designed to if the furnace is not installed correctly.

We have built our reputation on providing the best installations in the industry ensuring our customers are “getting what they paid for”. This is just one of the reasons why Carrier chose us to be a Factory Authorized Dealer.


Our installers take pride in what they do. They make every effort to ensure the job is done right the first time. Before starting an installation, they protect your home with floor coverings and will take the time to go over the procedure with you and discuss where any holes will be drilled for venting. When they are finished they will go over the work performed with you and then make sure you understand how to operate and maintain your new furnace. If there is anything you are not quite happy with they will gladly make any adjustments needed to ensure you are completely satisfied with your new furnace installation.
