• The ABCs of HVAC

    All you need to know about HVAC. Starting with what HVAC stands for.

    It’s pretty easy to take the air you breathe for granted. But the fact is, there’s a lot to know about the heating and cooling systems in your home. And this is the place to start. (Especially if you want to take another thing for granted: Say, low energy bills.)

Systems that are at home in any home

Your drapes, fabrics and paint colors were all chosen with care to suit your home and tastes. Your heating and cooling system should be just the same. That’s why we offer our innovative products in four configurations. One is sure to meet your needs perfectly.

Split systems

A split system simply means your solution has products that reside both inside and outside your home. In many cases, a split system consists of:

  • Furnaceprovides heating and the fan used year round to circulate air
  • Evaporator coilthe indoor component of your outdoor cooling unit
  • Air conditioner or heat pumpworks in tandem with the evaporator coil
  • Ductscarry the conditioned air throughout your home
  • Control or thermostatyour interface for controlling your system
  • Optional air quality accessoriesclean, humidify, and freshen air before it circulates throughout your home

Some split systems consist only of an outdoor unitsuch as a heat pump or air conditionerand an inside fan coil. If that’s the case, there’s usually another heat source in the home like baseboard heat or a boiler.

Hybrid Heat® split systems

It’s a smarter version of your standard split system, with an energy efficient twist: In addition to gas furnace heat, this system automatically figures out how to get the best efficiency by also using an electricity-fueled heat pump to provide warmth. Bonusthe heat pump functions in the place of an air conditioner too.

In the warmer, humid climates of the south you might consider a high performance heat pump with a lower efficiency and lower up front cost furnace so you can have the furnace as backup heating on really cold nights, while taking advantage of the high-efficiency heat pump most of the year. A heat pump with a variable-speed compressor matched to a furnace with a variable-speed blower motor can do an amazing job of pulling humidity out of the air in the summer to save money.

Meanwhile, in colder climates, it’s best to pair your heat pump with a high-efficiency furnace. Despite the cold, you might be surprised by just how much mileagenot to mention cost-saving efficiencyyou’ll get from a heat pump in the spring, fall and, yes, even winter months.

A Hybrid Heat system includes:

  • Heat pumpprovides summer cooling and dehumidification and warmth in cooler seasons
  • Evaporator coilthe indoor component of your outdoor heat pump
  • Furnaceprovides heating and the fan used year round to circulate air
  • Ductscarry the conditioned air throughout your home
  • Control or thermostatyour interface for controlling your system
  • Optional air quality accessoriesclean, humidify, and freshen air before it circulates throughout your home

Ductless split systems

As you may have guessed from its name, a ductless split system doesn’t rely on air ducts to spread treated air in your home. Instead, this specialty system is designed to heat or cool room additions or other places that may lack ductwork, such as home theatres, exercise rooms, garages or any other area where the existing system doesn’t quite cut it. Ductless split systems include:

  • Small outdoor air conditioner or heat pump unit
  • A compact indoor wall unit
  • Refrigerant tubing and wire connectionspass through a small hole from indoor to outdoor unit to connect the system.
  • On unit or remote controlyour interface for controlling your system

Packaged systems

Some homes just don’t have space inside for a furnace or the coil needed for cooling. That doesn’t mean they can’t be filled with the same comfort and improved air quality of a split system home.

Packaged units tend to all look alike but can do vastly different things:

  • Cool only as an air conditioner
  • Cool and heat as an electric heat pump
  • Cool and heat as a Hybrid Heat® dual fuel system of gas furnace with electric heat pump
  • Cool and heat as a gas furnace with electric air conditioner

As an all-in-one unit, the only other thing you need is a control or thermostat and, of course, ductwork to carry the conditioned air. Additionally you can add air quality accessories if you like. Packaged systems may be located on the exterior of your home, either on a flat rooftop or in the yard.

Geothermal Heat Pump System

Traditional heat pumps do the same thing as air conditioners but in winter, they do it in reverse, drawing their heat energy from the outside air. Geothermal heat pumps don't have to rely on the potentially wide temperature swings of outdoor air. They tap into the relatively consistent and more moderate temperatures of the earth instead. Using your yard, pond or well water, this ingenious technology enables you to enjoy higher energy efficiency inside your home—no matter how extreme the weather gets outside.

There are geothermal systems that can serve homes with ductwork or homes with radiant heat. The radiant heat versions are referred to as hydronic systems and some of those can also provide you with all your hot water needs.

A geothermal system can be used to provide all of your heating and cooling needs or you can pair it with a furnace for a dual fuel heating solution.
