At Advantek Service Group we have the belief that the educated customer is the best customer we can have. So with the help of Lennox Industries we have provided this page.

For most of us, our understanding of home heating and cooling begins and ends with the thermostat. We turn it up for heat and down for cooling, but we're not exactly certain how or why it works the way it works. Below you can find out how you stay cool in the summer, how a "Heat Pump" works and how "Lennox" latest comfort system "CompleatHeat" could be the best thing you could do for your home.

Remember your HVAC system is the most expensive mechanical device in the home. As an informed consumer you can make better decisions about your home comfort. That's good for you and good for us, because keeping your "Whole Home Comfortable"   is our No. 1 concern.

How AC Works

Air conditioners cool your home by removing heat from the indoor air and transferring that heat to the outdoor air.
This heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. The heat is then carried by lines to the outdoor unit, where it is released to the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.


Heatpump (winter)

The electric heat pump heats your by moving existing heat from one area to another. An outdoor coil absorbs heat which exists in the outside air and transfers it via refrigerant lines to the indoor coil, where it is released to warm your home.

An auxiliary (back-up) electric resistance heater is an option which works with the heat pump when the outdoor temperature goes below the balance point (the point where your home's heating requirement is greater than the heat collected by the electric heat pump alone.)

In the summer, an electric heat pump cools your home by removing heat from the indoor air and transferring that heat to the outdoor air.
This heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. The heat is then carried by lines to the outdoor unit, where it is released to the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.



How Complete Heat Works

The CompleteHeat™ unit consists of two modules, [1] a heating module that produces heat and [2] an air handling module that sends warmed air through your home's heating ducts. The modules can be installed together or separated to meet specific application requirements. [3] The process begins when water fills the water storage tank through the pipe at the top of the heating module. When heat is needed to warm your indoor air and water, [4] the heating module tells the combustion blower to draw in outside air which is used for combustion. This means the system doesn't waste your home's conditioned air. After a short safety delay, [5] a fuel mixture is sent into the burner where it is ignited by an electronic spark. The ignited fuel is super-hot [6] and, as it moves through the stainless steel coil within the water storage tank, the water in the tank is heated to 120 degrees F. (49 degrees C.) or your preferred temperature.
After the combustion products have traveled all the way down through the coil in the tank [7], condensate (water) is separated and drained, and exhaust gases are vented safely out the top of the unit and on through the PVC piping to the outdoors. [8] Hot water is directed to your faucets through plumbing at the top of the heating module. [9] The same fuel that heats your water also heats your indoor air. When your home's thermostat senses a need for heat, [10] a small water circulating pump draws hot water from the heating module and sends it through the space heating coil in the air handling module. [11] The hot water in the coil warms the surrounding air.

The blower [12] turns on only after the coil has been heated and [13] warmed air is then sent throughout the air duct system into the rooms of your home.

Water [14] is continually recirculated back into the heating module to be reheated until your home reaches your desired comfort level.

Each step in the CompleteHeat process works toward making your home more comfortable and energy efficient, and providing more hot water than ever before.
