What is an HVAC system?
Commonly abbreviated as HVAC, your home heating and air conditioning unit is probably the most sophisticated systems in your home. With a simple push of a button, you can make your summers bearable and turn up the room temperature in the dead of winter.
What are the various types of the HVAC systems?
So what is HVAC and are there different systems available? When purchasing as central heating system for your home, you can have your pick from several types. A split AC system comprises two components - an outdoor unit and an indoor unit - and is commonly referred to as central air conditioning. Such systems suit warmer climates as they are quite effective in lowering the home’s humidity in addition to keeping it cool. It is practically noiseless because the compressor unit sits outside the house. It also bears the additional benefit of air filtration, removing airborne particles such as pathogens and dust. A ductless system on the other hand, is a form of central AC systems that work in a single area or room of the house. As a result, it does not require any ducts to move the air, hence the term ductless. It consists of a compact outdoor condensing unit and an equally small interior evaporator unit that hangs on a wall to direct airflow. As a result, it is quite inconspicuous, making it an excellent option for garages and attics that serve as living spaces, and it only requires standard HVAC maintenance. In addition, they are quite energy efficient and do not lead to a sudden spike in your energy bills. This is quite handy when your home does not have or cannot incorporate a duct system. They also make an ideal choice for people carrying out home remodels that would call for an extension of the duct system.
HVAC installation: How does central cooling work?
The split system is the most popular HVAC installation, and it comprises an outdoor component with a compressor and condenser as well as indoor evaporator coil. HVAC services will also install an air handler or a furnace to help with the heating. The AC unit brings about a cooling effect in your home by blowing the warm air to the indoor evaporator coil. The heat energy transfers to the liquid refrigerant inside the coil, leaving the air colder that it was before. The unit then pumps the refrigerant back to the compressor, and the cyclic process repeats as long as you keep the unit running. Similarly, the air conditioning unit moves the heat absorber by the refrigerant outside the home while blowing the cooler air inside the house. The unit also absorbs and condenses air moisture that could lead to humidity building inside the room and drains it outside. Because they share the same duct system, your cooling system often pairs with the central heating unit. You will need to retain the services of credible HVAC companies to carry out the HVAC installation.
What is central heating?
A central heating unit comprises a heating appliance such as a furnace that HVAC services install in the garage or your basement. Furnaces comprise four main components: a burner to deliver and burn fuel, heat exchangers, a blower and a flue that removes the gaseous byproducts. You can have a choice of systems that run on fuel, gas, oil or a hybrid system that combines two fuel types. You should consult an HVAC repair service to help you make the best choice. As the heating unit runs, it produces combustion gases in the burner that pass though the heat exchanger. As the cold air from your home blows past the heat exchanger, it becomes warm and the unit blows it into the duct systems. From the tubes, the hot air travels to the various parts of the home. The heating systems work in conjunction with the central heating unit during the warm seasons of the year to keep your home cool. The air cools as it passes the unit’s cooling coil that is often attached a fan on the furnace that circulates it back to the ducts systems. Proper HVAC maintenance keeps the system running smoothly and efficiently, which increases its lifespan.
How do you control the heating and cooling system?
The thermostat is the nerve center of the home’s HVAC services, enabling you to control the temperature levels and turn the system on and off. A heat-sensitive device, it boasts that ability to detect and control changes in temperature. You only need to set your temperature preferences and the handy device will do the rest. When the temperatures in your home rise or fall below the ideal temperature, it acts accordingly to bring them back to the right level. The thermostat turns the furnace either on when the temperature fall or off when they get too high. It comprises of a bimetallic element that expands or contracts in response to the temperatures in the home. Older thermostats feature exposed parts and comprise of a series of bends. Modern models, on the other hand, do not have any open elements as they are safely tucked behind the glass. They comprise a steel bar and a series of magnets and contact points that complete an electric circuit after the temperature drops. Credible HVAC repair services advise that the newer models are more effective than the older models in addition to being more durable. HVAC companies help you answer what is HVAC and often carry the best range of thermostats that integrate readily with modern systems.
Getting the best unit for your home: Advice from HVAC companies
If you live in a warm, humid area, you are better off with a central heating unit because it combats both the temperature and humidity to create the ideal environment. HVAC companies recommend units take the size of the home into account when picking out a unit to increase efficiency and keep your energy bills low. Similarly, you should keep an eye out on the energy efficiency of the unit as it contributes significantly to the running costs. Typically, you should hire an expert to carry out the installation and answer any questions you have pertaining to what is HVAC.
