Even though the unit seems to be running fine it could still be on the verge of failing.
There can be a number of reasons for a noisy air-conditioner such as a dirty blower evaporating coil, foreign objects in the condenser unit, the motor or fan blade etc. It is advisable to call in a professional to assess and repair the problem.
When the room reaches its set temperature, the condenser stops operating.
Once the temperature rises it will resume operation.
Possible reasons could be:
It is normal for water to drip from the condenser as condensation takes places when warm air surrounds the piping condensate.
Air-conditioner water discharges through a drainage pipe that runs from the fan coil unit to the drain.
Water will start leaking from the fan coil if:
No tray or receptacle should be placed beneath or on top of an air-conditioning unit as this can create conditions favourable for mosquito breeding.
This is due to the smell of the room, furniture, cigarettes etc., being absorbed into the unit and being discharged together with the airflow. When this occurs it's advisable to call a qualified serviceman to service your air conditioner.
The life span of the air-conditioner is shortened, efficiency decreases and water leaking problems may occur.
These factors also cause an increase in electricity consumption.
All buildings have indoor air quality or pollution problems, they just differ in severity.
The source can be internal, or from outside air that enters the building.
All premises have some problem with dust which is usually most noticeable while you're dusting.
There are also fumes from paint, hairspray, cooking, numerous aerosols, chemicals, plastic molecules, machinery and others, continuously being discharged into the air.
1. Determine the areas that require air conditioning.
2. Determine the cooling capacity required. (see below)
3. Determine the type of air conditioner that you want.
A commonly used quick estimation rule of thumb, for average room height, is:
Area (Length x Width) x 650 = BTU/hr
Eg. Room size 5m x 5m = 25m² x 650 = 16250 BTU/hr.
However, there are too many variables for this to be relied upon in every instance.
The only way to accurately determine the HVAC capacity is to have a professional evaluation.
There are many good quality air conditioner brands on the market today that offer similar functionality. We assist you with making a selection based on your specific requirements rather than just opting for a particular brand name.
Regular servicing helps keep your system in tiptop condition and is critical to making your equipment last a long time and run efficiently, and pays for itself in the long run.
Small problems can be detected before they become serious problems.
No one wants their air conditioning system to fail in the middle of the night or on the hottest day in the afternoon.
It is impossible for any company in the air conditioning industry to offer the cheapest price, have the highest all round quality, provide the best service, and stay in business long enough to back up their products and services - all at the same time.
Your decision in choosing an air conditioning contractor should be based on the overall service which you are going to pay for and receive.
More efficient equipment, better-trained technicians, and reliable service and products may initially cost more, but will save your company time and money in the long run.
An air handling unit is the component in an HVAC system, which conditions and circulates air. The larger industrial / commercial air handlers are usually housed in a metal casing containing a blower, heating/cooling elements, filter racks/chambers, sound attenuators, and dampers. Air handlers are usually connected to ductwork that distributes the conditioned air through the building and returns it to the AHU.
An air handler designed for outdoor use, is known as a packaged unit (PU) or rooftop unit (RTU)
The amount of energy that's needed to change the temperature of one pound (.454kgs) of water by one degree Fahrenheit.
A system in which air is treated at a central point and carried to and from the rooms by fans and ducts.
An air conditioning system that has no refrigerant in the unit itself. Due to their efficiency, these systems are commonly used for large HVAC installations.
Comfort air conditioning systems are designed for human comfort and not for protecting equipment.
The compressor cycles the refrigerant between the condensing unit and the fan coil unit.
An air conditioner condenser is a heat exchanger component. The condenser unit takes in hot, high-pressure refrigerant gas, which is condensed to a sub cooled liquid.
A refrigerating mechanism which pumps vapourised refrigerant from the evaporator, compresses it and liquifies it.
Ducting (piping), referred to as ductwork in HVAC systems, can be used to supply, ventilate, return, and exhaust air. Duct design involves detailed planning, such as sizing, layout, pressure tracking and maximisation. Duct piping can be made out of various suitable materials.
An air conditioner unit that is installed inside the building and can be freestanding, wall mounted or ceiling mounted.
A device used to remove particles from the air, and to protect the HVAC equipment. Filters vary greatly in particle arrestance capabilities.
Heating, Ventilation, and Air Conditioning.
This is installed inside the building or covered area and contains the indoor coil, fan, motor, and filtering device.
As opposed to having the air-conditioner working at maximum capacity or switched off, an inverter regulates the rotational speed of the compressor. This reduces the number of times the compressor stops and starts.
A self-contained heating and/or air conditioning system designed for outdoor use, is known as a packaged unit (PU) or rooftop unit (RTU).
Precision air conditioning systems are designed for equipment cooling, and not for human comfort.
A heating and air conditioning system that has all of the components encased in one outside unit.
A single-split unit consists of the outdoor unit (condenser) and indoor unit (fan coil).
A multi-split unit consists of the outdoor unit (condenser) connected to more than 1 fan coil unit thus having the capability to cool more than one room.
