TYPES OF FURNACES
Single Stage Furnace (Natural Gas or Propane)
You've probably lived in a house with a single stage furnace. The gas flame is either on or off. Consequently, the furnace waits for the temperature in the house to get cold--often colder than comfortable--before firing on. Then, the furnace rams the house full of heat until the thermostat shuts the system down. You're left with a lot of heat build-up, which is great if you're a "cold-blooded" person but bad for your energy bills. For a target of 72 degrees, actual temperatures in your house might range as low as 68 degrees and as high as 76 degrees. Single stage furnaces are the most wasteful in terms of energy, but they are the lowest cost to purchase. If you are interested in this type of furnace, Calverley Heating & Cooling, Inc. recommends American Standard's Silver ZI Series:

Two-Stage or Dual-Stage Furnace (Natural Gas or Propane)
The two-stage furnace is a little smarter than the single stage furnace. Rather than a simple on/off operation, its flame can be on/high, on/low, or off. Adding this second flame setting makes a dramatic difference in energy costs. Two stage furnaces are much quieter than single stage furnaces and slightly higher cost. For a target of 72 degrees, actual temperatures in your house might range as low as 70 degrees and as high as 74 degrees. If you are interested in this type of furnace, Calverley Heating & Cooling, Inc. recommends American Standard's Gold ZM or XM Series:

Modulating Furnace (Natural Gas or Propane)
This furnace adjusts its flame incrementally so that the true temperature never varies more than 1 or 2 degrees from the thermostat's target temperature. In terms of comfort, it's the most comfortable gas furnace you can buy because you avoid those long, cold periods (found in single and two stage furnaces) and high build-ups of heat when the furnace eventually responds. In addition to a variable flame, the blower is variable according to demand. For a target of 72 degrees, actual temperatures in your house might range as low as 71 degrees and as high as 73 degrees. Modulating gas furnaces are among the most energy efficient furnaces and are rated at 98% efficiency. These are also the highest cost furnaces. AFUE, or Annual Fuel Utilization Efficiency, according to EnergyStar, "measures the amount of fuel converted to space heat in proportion to the amount of fuel entering the furnace. This is commonly expressed as a percentage." If you are interested in this type of furnace, Calverley Heating & Cooling, Inc. recommends American Standard's Platinum ZV Series:

Electric Furnace (Air Handler)
An electric furnace is a furnace that runs using electricity as its main power source to both generate heat and push the air through the central heating system. In many cases, an electric furnace is considered one of the most costly types of furnaces to run. However, in some cases, especially where there is a lack of natural gas infrastructure or where it does not get very cold, it may be one of the few convenient options available. The electric furnace works by using electricity to heat elements inside the furnace structure. A fan then draws cold air from intakes and forces it past the heating elements, which heat the air and send it into the home. The process is very similar to the way a forced-air space heater may heat a room. Many may be surprised to learn that an electric furnace is one of the most efficient types of furnaces to run, if one is looking strictly at the heat loss aspect. There are no noxious gases being created and therefore no need to have flues or other discharges for those heated gasses, so all heat goes into the home. However, when compared to natural gas or heating oil, electricity tends to cost more, making it a bad choice from a price perspective.

TYPES OF AIR CONDITIONERS
Split systems are the most common type of central air conditioner found in the U.S. Inside the house, tucked in a cabinet, is the evaporator coil, which removes heat and moisture from the air. Outside the house, a metal case contains the condenser coil, which releases the heat, and the compressor, which pumps refrigerant between the two coils. The indoor component of the air conditioner is connected to a network of ducts, and a blower circulates the cold air through them to reach all parts of the house. This type of system is the most economical to install in a house with a central furnace, because it can share the duct work used by the heating system. If you are interested in this type of air conditioner, Calverley Heating & Cooling, Inc. recommends you review this product literature by American Standard:
American Standard Split Systems Brochure - Click for InfoHeat pumps are a variant on the traditional split system. This is essentially an air conditioner that can work in both directions. During hot summer months, it pumps heat out of the house and releases it outside. In the wintertime, it extracts heat from the outdoor air and uses it to warm the house. Heat pumps can be used effectively for both heating and cooling in mild climates. However, heat pumps do not generally work well when temperatures stay below freezing for a long time, so they are not the best choice for cold climates. A specialized type of heat pump, called a ground-source or geothermal heat pump, may be more suitable for colder environments. It works by drawing heat out of the ground rather than the air.

Packaged central air conditioners combine the evaporator, condenser and compressor in a single unit. The air conditioner is usually placed on a roof or a concrete slab near the foundation. Ducts running through the exterior wall or roof draw air from inside the house and return cooled air indoors. This type of air conditioner can also be used in small commercial buildings. When combined with a set of heating coils or a natural gas furnace, it eliminates the need for a separate furnace inside the building.

Ductless mini-split systems can be a good choice for houses that do not have duct work. Like a basic split system, the ductless mini-split combines an outdoor compressor and condenser with one or more indoor air-handling units. These units are mounted high on the wall and have blowers attached. Tubing connects the indoor and outdoor units and circulates refrigerant between them. Each indoor unit is installed in a separate room and cools that room only, much like a window air conditioner. The main advantage of these systems is that they can be installed without tearing up walls to install duct work. They also allow the flow of cold air to be controlled independently in each room (or shut off altogether in empty rooms). Mini-split systems are more expensive than ducted central air conditioning systems, costing roughly 30 percent more for the same amount of cooling power. However, they are also more efficient, since they avoid the energy loss associated with duct work.
