reliability from experience - efficiency from innovation

Downsview Heating & Air Conditioning

HVAC systems have evolved in many ways. The increasing demands for better efficiency has lead to product designs that make better use of venting, heat exchangers and control systems. Along with increased efficiency, systems are now more compact.A more recent development in Canada is the adoption of tankless water heaters and dual mode boilers.

For the builder these advances have provided more HVAC options. Selecting from the many options in home comfort systems requires both knowledge of the products and experience with installations. At Downsview Heating & Air Conditioning we constantly search for innovations in products. Our criteria for product selection are largely based on meeting the changing demands of the home buyer.

Our criteria include the following:

Today's new home construction projects generally offer a mix of single family, townhouses and multitiple unit housing. Each style of construction brings a new set of factors that need to be part of the HVAC design and selection process. We have established a strong relationship with top brand equipment vendors that offer innovation and quality in their products. This is the only way we can meet the demanding needs of today's new home construction industry.

Heating & A/C Products - With Improved Energy Efficiency

We provide a full range of conventional home comfort options for your housing project. These products are priced cost effectively and with high energy efficiency ratings that help to keep the utility costs manageable. We select from manufacturers that have an established history of quality and reliability.

Tankless Water Heaters

A Tankless Hot Water unit heats water entirely on demand, only when it is needed. When a hot water faucet is turned on and the water begins to flow, information is collected based on flow, incoming water temperature and other factors. With this information the unit determines the amount of heat needed to maintain the water temperature set point. The water flows through the internal heating modules and exits the unit at the desired temperature. The start-up process takes a couple of seconds. A convenient thermostatic control and digital display on the front of the unit or a remote allows the homeowner to select an desired temperature.

Sensors continue to monitor the water flow rate and incoming water temperature as long as the water is running. These snsors send constant and continuous data so that the heating elements can be modulated in accordance with changes in flow rate and incoming water temperature. If, for instance, the flow rate increases because a second demand for hot water in the home is initiated, the unit will increase its heat output to maintain a consistent and precise output temperature.

The tankless water heater will remain on until the hot water faucet is closed. As soon as the flow sensor detects that water has stopped flowing, the power to the unit is completely turned off. Based on the specific capacity, measured in flow rate (gallons per minute - GPM), of a particular model, there will be a limit on the amount of hot water available.

The performance of Tankless Water Heaters can degrade as the number of hot water faucets turned on increases within a home. A better balance in performance can be achieved by combining a Tankless Hot Water systems with an energy efficient passive storage tank. The storage tank provides a buffer during high water demand periods while retaining the efficiency of the Tankless Hot Water system to heat the water.


Dual Mode Boiler System - Water and Home Heating

The Dual Mode system takes the efficiency of the Tankless Hot Water design and applies it to both heating hot water and heating the home. This approach eliminates the need for a gas fired furnace and the associated venting. A smaller air handler is all that is needed for home heating.

The correct design of a dual mode system and the selection of the various components is essential for proper operation in a given style of home. Our experience with many products, manufacturers and the performance of various components has lead to the development of proven and reliable installation practices.

Another significant advantage of a Dual Mode system is the extremely compact space requirements. We have designed installations that can even be installed into a closet space. This provides a viable and cost effective solution for multi homeowner/multi level housing that provides each unit with individual hot water and home heating systems.

High Velocity Air Handlers - Improved efficiency and comfort

The AIRMAX system offers a significant innovation in the air distribution method for home heating and cooling. With the use of an Electronically Commuted Motor, efficient air circulation is achieved with small ducts. There are many advantages with this design for both the builder and the home owner.

The MAXAIR fan coil is so compact that it can be installed anywhere, even a closet. The unit achieves a space savings of 50% over conventional heating and air conditioning systems. This compact space requirement makes the AIRMAX particularly suitable for multiple level housing units.

Installation is simple and cost effective. The 2 1/2 inch supply duct will fit in a standard 2" x 4" wall cavity. Outlets can be placed in the wall, ceiling or floors. The AIRMAX can be combined with a boiler system for heating, conventional air cooling systems, humidifiers and high efficiency air cleaners.
