When most homeowners in Mansfield, Connecticut, think of HVAC units they think of a box with a big fan that sits outside their house providing heating or cooling to their home when necessary. It is not quite that simple because there are different types of central heat and air units; some have different features inside, different methods of power or other options that enable them to provide other comforts in addition to just heating and cooling. To help us out, Adam McKenzie of Fenton River Heating and Plumbing provided a brief description of the different types of central heat and air systems available in todays marketplace.
SINGLE STAGE HEATING AND COOLING SYSTEMS
These are very popular types of systems that are found in climates that tend to be particularly cold a majority of the year or hot and humid on a long term basis. They do a great job of providing comfort at these temperature extremes. The drawback with single stage systems is that operate at full capacity even when running on days that are just moderately hot or cold; this makes them very energy inefficient.
MULTI-STAGE HEATING AND COOLING SYSTEMS
These systems give you an advantage over single stage systems because they are designed to work at different capacities depending on how much heating or cooling is called for. They are a lot more efficient than single stage systems. Other benefits they offer are quieter operation because they do not kick on full power immediately and they offer better air filtration when they are running on lower speeds. Most new installations are done with two stage systems.
ENERGY SAVING ZONED SYSTEMS
If you have an area of your house such as a sunroom that you dont use in the winter, it is a waste of energy to heat that room as warm as the rest of the house at that time. Zone systems will let you cut off heat or air conditioning to unused areas of your home and save you a lot of money in the process. They work by incorporating valves into the ductwork that are activated on or off at the master control switch of the system. They can even be programmed so you do not have to constantly open and close valves manually.
HUMIDITY CONTROL SYSTEMS
These types of systems are an upgrade to conventional heating and cooling systems because they add a humidity component into the mix of operations they can do. These are extremely useful in very humid or excessively dry climates. They are designed to keep the homes they are installed in at the optimal 50% relative humidity that is perfect for your body.
There are even kits that are available to make your existing central heat and air units more energy efficient and add to their heating and cooling efficiency too. They do this by incorporating such things as vents into exhaust pipes that can be closed when the system is not running and by adding electronic ignition so pilot lights can be eliminated and not constantly use up gas to stay lit.
