Stay warm in the winter and cool in the summer with Vedhas

Vedhas install air conditioning systems & appliances. To cool and heat areas providing indoor air quality with thermal comfort.

They include various forms of cooling, heating, ventilation or disinfection that modifies the condition of the air. An air conditioner (AC, A/C or air con unit) can be a single appliance or a system designed to stabilise the air temperature and humidity within an area, (used for cooling as well as heating depending on the air properties at a given time).

The selection of the most appropriate air conditioning system becomes a conflict between achieving the best aesthetic look, saving space, cost & the practicalities of installation.

Our expertise extends to a wide variety of areas including, but not limited to:

• Office air conditioning and climate control

• Retail air conditioning and climate control environments such as cafe's, shops, restaurants and pubs.

• Residential and domestic air conditioning

• Air Conditioning, heating & climate control for schools, universities & colleges.

• Healthy climate controlled environments for healthcare services, doctors surgeries, hospitals & dentists.

• In room air conditioning, cooling & heating for Hotels, conference rooms, wine cellars and kitchen areas

• Air conditioning for leisure venues such as museums & sports stadiums

Air Conditioner Size Selection Guide

Air conditioning sizing requirements will vary subject to a number of factors. These factors include the aspect positioning of your house, the material the house is made of such as brick veneer, double brick or weatherboard. The location and size of windows and the covering on these windows and whether the house in insulated has a large bearing on the sizing. All of these factors combined with the region you live in can vary the air conditioning requirements.

To be sure you purchase the unit that best suits your situation we recommend you discuss your specific requirements with us so we can design the best unit for you free of charge.

 

Q: What are the benefits of Air Conditioning?

The major benefit is to give a comfortable environment at home or the office throughout the year. An air conditioning unit has a number of functions including heating, cooling, dehumidifying and fan only. This will enable you to set the temperature and the unit will cool or heat as required or in the case of dehumidify, the unit will get rid of the moisture in the air without dropping the room temperature which is beneficial for those with Asthma.

 

Q: What are some of the types of air conditioners available?

SINGLE ROOM AIR CONDITIONERS - One-piece unit, which must be installed in an external wall or window. These can be available in Reverse Cycle or Cooling only.

SPLIT SYSTEMS – Generally two piece units (but can be more in the case of multi splits) consisting of an Indoor and Outdoor Unit. Split Systems are available as Reverse Cycle or Cooling only. These are available in fixed speed or inverter.

DUCTED SYSTEMS - Ducted air conditioners are able to condition whole or part of a house. This is a highly specialised area and should only be undertaken by a qualified contractor.

PORTABLE UNITS - One piece or split systems. One piece unit has flexible duct to disperse hot air. The split system has an outdoor condenser. Portables are spot coolers only and are not designed to cover large areas.

 

Q: How about Air Purification?

Depending on the model, use either Plasma or Bio Filtration which absorb and decompose harmful bacteria, allergens, odours, dust and toxins for cleaner, healthier air. Contamination Control Laboratories conducted laboratory tested against

 

Q: Service and Maintenance?

Depending on the environment, it’s recommended the filters be cleaned every 2 weeks or at least once a month. In addition, a professional tradesperson should clean the unit at least once a year; this should be done before summer, as there will be long delays during the summer period.

 

Q: What are the installation requirements?

Allowance must be made for drainage from indoor unit on cooling mode and outdoor unit on heating mode. Positioning of the indoor unit is important and should not inhibit the flow of air from the unit. Where possible the unit should be placed centrally on a wall directing the airflow to the centre of the room. Outdoor unit must be positioned in a well-ventilated area on a solid footing and must be easily accessible for servicing purposes. Correct installation is vital to ensure the performance of the unit. As installation faults may void manufacturer warranties, only qualified air conditioning installers should carry out this work.

 

Q: How about Insulation?

When insulation is installed significant savings can be made on the running costs of air conditioning and a lower wattage unit could be installed, i.e. Saving on the purchase cost.

 

Q: What are some of the factors to consider when buying and installing split air conditioners as well as window mount units?

Make sure the unit you purchase is correctly sized allowing the unit to cycle off when the correct temperature is reached. This allows for the compressor to switch on and off as required rather than running continuously.

Set your thermostat so that you feel comfortable rather than cold. Most of us feel comfortable at between 24 and 26 degrees in summer. Remember that in summer you will be dressed in summer attire.

Consider insulating the ceiling so that you may be able to use a smaller capacity unit.

Make sure the unit is securely mounted to avoid unnecessary vibration. Mounting through the wall will generally give a more secure install than through glass.

Maintain the filters of your air conditioner on a regular basis and in the case of split systems, have your unit serviced by a qualified tradesperson at least every two years depending on the environment the unit is installed in, some units require a professional service once a year.

 

Q: What are some of the factors to consider when locating your outdoor unit?

Is the unit going to be sitting on a concrete path or in a garden? Concrete paths are a highly reflective surface and will allow sound to travel further. A condensing unit mounted close to an adjacent wall will allow sound to be reflected off multiple surfaces making the sound louder.

Be sure to have maximum clearances around the outdoor unit, so there is no chance of the hot air from the outdoor being re-circulated back into the outdoor unit especially if there is a wall directly opposite the unit. As this can cause the unit to over heat and fail especially on hot days.

Is the condensing unit going to be located under a carport or roofed entertainment area? These areas are more reflective of sound.

Is the condensing unit mounted on brackets on a wall? Make sure the unit is well isolated from the wall so as to avoid unnecessary vibration.

Is the fence between you and your neighbour's house a solid fence or a paling fence with gaps? A solid fence will not allow as much sound through.

 

Q: General Information of Interest

Horsepower is a measure of the rating of a compressor and does not relate to the cooling capacity of an air conditioner. Use watts or B.T.U.

Placing the outdoor unit in direct sunlight makes the outdoor unit work harder.

In cooling mode remember that the method of sizing most commonly used is designed around a maximum differential of around 10 degrees.

Most of us feel comfortable at between 24 degrees and 26 degrees and at a humidity level of 60% to 75% in summer and 55% to 70% in winter.

Over sizing is just as bad as under sizing as the unit may cycle off before the appropriate amount of dehumidification has occurred.

Installation is important. If a unit fails due to a problem with the installation (faulty flare connections etc.) it will not be covered under the warranty.

Location of the outdoor unit must be easily accessible.
