If you are looking for the ultimate in energy-saving climate control, Heating, Ventilation and Air-Conditioning (HVAC) systems offer the perfect climate control, providing both warm and cool air as it is required. There are two main types of HVAC system; commercial and domestic, and for the purposes of this article, we will look at domestic climate control systems, which are basically designed around the home.

Heat Transfer

The core principle of HVAC systems is the transfer of heat, which is achieved using thermal heat exchanger units that turn cool air into warm or vice-versa. Hot air is fed through special coils, which cools the air that is them pumped through the building via galvanised ducting, or in a cold climate, the cool exterior air is warmed up then fed through the ducting to maintain the desired temperature.


Single state air-conditioning systems only provide either heating or air-conditioning, depending on your needs – if you wanted to cool the interior, you would visit an A/C shop in Bangkok, whereas if you wanted heating in London, you could use a single state HVAC system to provide heat. When looking for cost-effective climate control, you should ask the engineer to pay you a home visit, where he can take a look at your living space and make a recommendation for an energy saving HVAC system that is designed around the property and your needs.

Special Components

The average HVAC system incorporates the following components:

  • Compressor – The powerhouse of the system.
  • Evaporator – This device removes air from a warm space by exchanging it with a refrigerant.
  • Condenser – This device pushes the heated air to the exterior.
  • Expansion Valve – This creates a pressure drop.
  • Heat Pumps – Can be used to either heat or cool a space.

Cost-Effective Climate Control

If you install a state-of-the-art HVAC system in your home, along with door stops and draught excluders, the interior will always be comfortable, and when compared to a regular A/C system, HVAC is more economical and therefore is the preferred solution. If you would like a quote to replace your old A/C with a top-rated HVAC system, a Google search will help you to locate a local supplier, and they would be happy to pay you a home visit and quote for the project.

Improving the Air Quality

It isn’t only the temperature you can control with HVAC, as there are special filters that remove contaminants from the air, leaving your interior smelling clean and fresh. Of course, these filters do need to be cleaned regularly, which is one of the tasks that the engineer would perform when carrying out essential maintenance, including the following:

  • Air filter replacement or cleaning.
  • Cleaning the transfer coils, compressors and heat pumps.
  • Inspect fan motors – Repairing when necessary.
  • Looking for leaks or signs of corrosion.

Whether you are looking to have an HVAC system designed for your new build, or would simply like to replace your aging A/C system, talk to an HVAC engineer and see what he can do for you.
