Furnaces heat and circulate warm air in the winter. Furnace heating ability is measured with an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace.
A split system heat pump keeps homes comfortable all year long. In the summer, it draws heat out of your home to cool it. In the winter, it draws heat from outside air into your home to warm it.
In a packaged system, all equipment is built into an outdoor unit, usually on a concrete slab or other platform. The “package” that gives it its name provides central air conditioning during the summer and heat in colder months.

Thermostats are extremely important because they are your interface and control system for your heating and air conditioning equipment. This is the device that will give you the information on what the equipment is doing, when it needs to be serviced, and allows you to set the exact temperature and humidity you want to maintain in your home.
Climate Master Thermostat
Mini splits are high efficiency ductless heat pumps ( up to 30 SEER). They are perfect for rooms where ductwork is not a viable solution and can be zoned up to five rooms. We use LG and Comfortaire Mini splits.
PTAC is a packaged unit heat pump. They are installed through the wall to a single zone ( 1 room ). Perfect for sun rooms or areas where a conventional system would be to large.
A traditional home comfort system has two parts: an outdoor unit, such as an air conditioner or heat pump, and an indoor unit, such as a furnace or air handler. The evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting. The refrigerant then flows back to the compressor where the cycle starts over again.
Zoning allows you to have different temperatures in each room or area of your house. You can have one temperature in the kitchen, another temperature in the family room, another temperature in your bedroom, etc. Not only does this provide much more comfort but it can save you up to 20% per year in your annual operating costs because you don’t overheat or overcool the areas that are unoccupied. The operating cost savings could be the equivalent to that of going from a 13 SEER air conditioning system to a 15 SEER system.
The geothermal process is based on a simple premise: Below the frost line – usually about 6 ft. deep—the earth is a constant temperature of 50 to 55 degrees all year long. During the winter, the heat pump absorbs heat from the ground and uses it to warm the air in your home. In the warmer summer months, the process is reversed, taking heat from your home and transferring it back into the ground. An optional hot water generator can create virtually free hot water in the summer and deliver substantial hot water savings in the winter. Learn More About Geothermal
