How do central heating systems work? The diagrams and descriptions in this section define central heating and air conditioning, forced-air furnaces, as well as radiant heating systems.Get a Local Heating Pro Fast! A central heating system has a primary heating appliance such as a furnace or boiler located in an out-of-the-way place such as a basement or garage. It delivers heat throughout the house either by pumping warmed air through a system of air ducts or sending hot water or steam through pipes to room radiators or convectors. With both forced-air and gravity systems, one or more thermostats turn the heating or cooling unit off and on as room temperatures rise and fall. Homes without central heating normally utilize electric baseboard heaters or, in some cases, in-wall or in-floor gas heaters or radiant heat. In contemporary homes, ducted air systems are the most common type of central heating and cooling. If your home has an air conditioner, heat pump, or furnace, it is a ducted air system.

There are two main types: forced-air and gravity. With a forced-air system, a furnace warms air, an air conditioner cools air, a heat pump either warms or cools air, and then a blower forces the heated or cooled air through the system and out into the living spaces. With a gravity furnace, convection currents (caused by the natural tendency of hot air to rise) carry heated air through the system from a furnace located on or below the main floor. Gravity systems do not have blowers, tend to have very large air ducts, and can only deliver warmed air. If your system includes an air conditioner or heat pump, it is a forced-air system. With these, cooled (and sometimes humidified or electronically cleaned) air is usually delivered through the same duct work and registers employed by heated air. An air conditioner runs on electricity and removes heat from air with basic refrigeration principles. A heat pump can provide both heating and cooling. In the winter, a heat pump extracts heat from outside air and delivers it indoors.

On hot summer days, it works in reverse, extracting heat from room air and pumping it outdoors. air handling unit historyLike air conditioners, nearly all heat pumps are powered by electricity. changing an ac unitThey have an outdoor compressor/condenser unit that is connected by refrigerant-filled tubing to an indoor air handler. commercial ac unit pricesAs the refrigerant moves through the system, it completes a basic refrigeration cycle, warming or cooling the coils inside the air handler. The blower pulls in room air, circulates it across the coils, and pushes the air back into rooms through duct work. When extra heat is needed on particularly cold days, supplemental electric-resistance elements kick on inside the air handler to add warmth to the air passing through it.

One of the ways we can help you achieve this goal is through a zoned heating and cooling system.What is a zoned system?A zoned heating and cooling system breaks your home into different areas or “zones”, each controlled separately by a thermostat. Zoning your home allows for several benefits including elimination of hot and cold spots and individual control of different rooms’ temperatures.How does a zoned system work?The secret to a zoned heating and cooling system is electronically controlled dampers in your ductwork. Dampers are like valves that control the flow of your heated and cooled air throughout your home.The second part of a zoned heating and cooling system is the thermostat. A thermostat is placed in each zone so that it can control the electronic dampers in your air ducts.When an area needs more air from your heater or air conditioner, the thermostat tells the damper to open up and let more air through.

Likewise when an area has reached its desired temperature, it closes the dampers and sends the air to the rest of your home.Why would I want a zoned system?There are several reasons Northern California homeowners zone their heating and cooling system, including:The most common use of a zoned system is to eliminate hot and cold spots. For example, most two-story or multi-level homes suffer from uneven heating and cooling. Because heat rises, the upper levels are always warmer than the lower levels.To combat this, at least two zones are installed – one upstairs and one downstairs. As one zone reaches the desired temperature, the thermostat slows the flow of air to that zone, which forces more air to the other zone and creates more even temperatures throughout your home.Different comfort levels for different family membersAnother common use of a zoned home heating and cooling system is to meet the temperature demands of different family members without fighting over the thermostat.A zoned system lets you control the temperature of each area independently.

If someone in your home likes it much colder or warmer than the rest of the household, this can be an ideal solution. A zone is installed in their bedroom, letting them change their temperature without affecting the rest of your home.Zoning your home heating and cooling system can provide a multitude of benefits.

Find Out Exactly What You Should Be Paid Comp Managers: Start Here » Job Description for HVAC Service Technician A heating, ventilation and air conditioning (HVAC) service technician starts an appointment with a customer by asking about any problems with the heating, ventilation, and/or air conditioning systems in the client's home or business.

From there, the technician will carefully examine the equipment in question to diagnose and troubleshoot the problem. Once the issue is determined, the technician provides the customer with a repair quote and, if authorized, begins to repair or replace defective equipment, mechanical components, or wiring in HVAC systems. An HVAC service technician might also be called upon by a customer to carry out preventative maintenance tasks or inspections to ensure that heating, ventilation, and air conditioning systems continue to run smoothly. A technician should have certification or an associate's degree from a technical or trade school that is accredited by HVAC Excellence, the National Center for Construction Education and Research, or the Partnership for Air Conditioning, Heating, and Refrigeration Accreditation. Formal training programs can last anywhere from six months up to two years. The job involves working with electrical equipment, so it is very important that a technician know exactly what he or she is doing or the job can get very dangerous very quickly.

If an education is not in the picture, it is sometimes possible to go through a formal apprenticeship program which can take three to five years and mixes on-the-job experience and training with classroom instruction. Exams for certifications are offered by a number of associations. A license to work as an HVAC technician is required in several states and can be obtained by passing a written test.
