Installation

Before installing any new central heating and air conditioning system, we recommend to know your options!

Central HVAC systems provide cool and warm air throughout the building via ductworks which are insulated and have vent covers located in walls, floors and ceilings.

There are 2 main types of central systems:

  1. Ductless systems
  2. Packaged systems

Ductless systems are divided to outdoor and indoor components. The condenser coil and compressor are located outside but the evaporator coil and furnace or heat pump are inside. Ductless systems are the best choice for places that already have a furnace but need an air conditioner.

Packaged systems hold the evaporator, condenser and compressor all in a single unit outdoor or on the rooftop.

Central Cooling

Central Heating and Air Conditioning

The cooling task of your central HVAC system is done by air conditioner. An air conditioner is like a refrigerator but it doesn’t have the insulated box. It too utilizes the evaporation of a chemical refrigerant to cool the air.

How does central cooling works?

A compressor makes the cool refrigerant compressed, making it hot and high-pressure gas. The hot gas goes through a set of coils in the condenser so it can release the heat and become a cool liquid. The liquid passes through an expansion valve and by evaporation becomes cold, low-pressure gas. The cold gas moves through a set of coils to absorb heat. A blower moves the air over these coils resulting in creation of cold air. The cold air is then pumped through your ductworks in the entire building. The refrigerant is pumped back to the compressor for the cycle to begin again.

The heat absorbed by the refrigerant is blown outside your building. Moisture that causes humidity is also condensed out of the conditioned air by humidifier.

Central Heating

Central heating system has a main heating appliance such as a furnace which is often located in your basement, garage or rooftop.

It can also use heat pump to distribute warm air more evenly. It works with electricity and creates less heat compared to furnace but it can act as air conditioner in the summer to cool the place.

Depending on your situation, you have the choice of electric or gas fuel sources or you can have a hybrid central system that can use both fuel types and provide backup system!

How does central heating works?

Gas fuel is flown to the burner in your furnace and passed through a heat exchanger. Air from your place hits the heat exchanger and becomes warm. It is then blown through ductwork to be distributed around your place.

In electrical furnace, electric elements which are controlled by circuit breakers produce heat instead of gas burner.

In warm months of the year, the central heating works with central air conditioning. The cooling coil of air conditioning unit is often attached to the blower of the furnace, so as the air is cooled, it is blown over and sent through ductworks in all rooms.

Central humidifier adds enough moisture to protect you from dryness symptoms and your walls and furniture from cracks.

Central HVAC advantages:

  • Heating options are flexible due to having ductworks so either a furnace or heat pump can be used for heating.
  • Temperature is more even in the entire place.
  • Air is filtered before being distributed in the building.
  • Humidity is controlled by removing excess moisture or adding when it is needed in dry environment.
  • Ductworks are built-in so they offer a more hidden look.
  • It lasts for 20 years.

Central HVAC disadvantages:

  • It requires ductworks through entire building which is high cost and maintenance and not to mention the messy installation process.
  • Ductworks are associated with 30% energy loss when air is moving throughout different parts of the building.
  • It will be heating and cooling rooms that are not necessarily used.
  • You will only have single temperature in the entire building unless you have zoning set up.

At Fairfax Mechanical we help you choose the central heating and air conditioning system that is right for you. We can customize the central system that best match your situation and let you choose from a range of high quality products with high Annual Fuel Utilization Efficiency (AFUE) ratings.
