Frazer and I are so pleased with our new natural gas furnace and hot water system. We were very impressed with the work done by the ATEL crew-Larry, Adam, Lance and Brad, and really appreciated their work ethic and professionalism.

Gas Furnaces

Furnace efficiency is measured by the annual fuel utilization efficiency (AFUE). Today’s models are 90 to 95%, which meet the Energy Star® standard of at least 90% efficiency. Install a new gas furnace today and you could save up to 40% off of your gas bill over your old standing pilot gas furnace.

Available Features

Single stage and 2 stage burners for improved comfort and even temperature throughout your home

Variable Speed Blowers (for greater energy efficiency and less air noise)

Zoned Climate Control (for individual floor and area temperature control)

Energy Star® Rating (to meet today’s energy saving requirements)

Up to 95% AFUE (for greater energy savings)

Air Source Heat Pumps

Heat Pump efficiency is measured by SEER (seasonal energy-efficiency ratio). The higher the rating, the more efficient the model. A SEER of 14.5 or higher is required to carry the Energy Star® label. More efficient units have higher SEER values that can go as high as 21 SEER.


  • Reduce your fuel bills: air source heat pumps run on electricity, so there’s no need to pay for gas, oil or solid fuels to heat your home.
  • No fuel deliveries required.
  • Can provide space heating and indoor cooling with same unit.
  • Can lower fuel bills, depending on what heating fuel you are replacing.
  • Can be easier to install than a ground source heat pump. Most air source heat pumps can be installed in one day.

Ultra Low Temperature Air Source Heat Pumps

Benefit from efficiences similar to a geothermal system without needing to dig or trench! Save up to 80% in energy costs with the new ZUBA-Central from Mitsubishi Electric. The ZUBA-Central is designed for the Canadian winter while offering high efficiency performance even with outdoor temperatures as low as -30ºC. We have customers (read reviews) who have saved over $2,800 over their old heating system in a single year. Contact us today for more details, we will get you saving on your heating and cooling bill as soon as we turn on your new Zuba-Central Heat Pump.


  • The secret behind Zuba-Central’s high-heating performance, even under extremely low outdoor temperatures, is Mitsubishi Electric’s exclusive Hyper-Heat Inverter (H2i) technology. It maximizes the benefits and efficiencies you can get from a heat pump. In addition, the unique defrost mechanism – which prevents automatic defrosting when not required – gives the system a quick start-up time and provides continuous heating.
  • Through the use of our VSCI Technology (Variable Compressor Speed Inverter) the Zuba-Central system is able to dynamically adjust heating and cooling capacities to match actual requirements of your home, which means you pay only for the required energy when you need it.
  • Zuba-Central is an Energy Star® qualified heat pump with a SEER of 15.0 in cooling mode and an HSPF2 of 9.4 in heating mode. Together with a high-efficiency ECM motor, you can be sure that you’re always getting the most from your utility bill and giving the most back to the environment.
