Condensing Unit Suggestions & Maintenance Tips for FAHU   

 In an air conditioning system, a condensing unit is often a high-side assembly. It consists of a mounting plate, a fan rotor, a compressor, a condenser, and controllers. It features a heat exchanger that cools and condenses the entering refrigerant vapor into fluid, and it also includes a fan that circulates exterior air through the heat exchanger component to cool the refrigerant interior. Small appliances for the home to extremely big commercial units utilized in the food and manufacturing industries—condensing units are available in a wide range of shapes and sizes.

Fresh air handling unit is referred to as FAHU. These are typically centralized devices that are used to provide the enclosed spaces with fresh air. These are present whenever there are restrictions on the absorption of fresh air, either directly or indirectly through Air handling units. FAHUs are either of regular construction, which uses a blower fan to circulate 100% clean air, or they are cleansed, which uses an extra cooling coil to introduce treated air into the small area without harming the indoor environment.

Listed below are a few maintenance tips for your fresh air handling unit:

Checking your components

Checking all the components of your FAHU thoroughly must be the first step on your agenda. Verify the functionality of the air dampeners, conditioning and heating coils, and regulators. Verify that all the belts and bolts are secure and are not damaged by aging or wear. Most of your ventilation requirements are exclusively dependent on this as it is the HVAC system's main unit!

Periodic change of filters

The simplest and most important FAHU maintenance advice is to change your air filters often. The equipment may have to work extra hard due to a clogged filter, which would reduce efficiency and raise power bills. Every so often months or as recommended by the vendor, filters must be replaced. Keep in mind that outdated filters might potentially pose a fire risk.

Programmable thermostat

By enabling you to select various temperatures at varying times during the day, a smart thermostat will enable you to conserve both money and energy. You may program the thermostat to reduce the temperature during the night or while you're away from home, for instance. This will assist you in lowering your energy costs and extending the lifespan of your fresh air handling unit. 

By compressing and pumping refrigerant via its evaporator coil, the condensing unit simply transfers heat from the air outside the structure. For the highest efficiency and greatest result, fresh air handling units and condensing units are designed to work in conjunction with corresponding units.

General tips on fan coil unit maintenance

 When was the last time you performed preventive maintenance on your fan coil unit? FCU units are used to heat or cool a room and are ideal for multiple small spaces that require individual temperature control.

Fan coil unit is a device which heats or cools a room using a fan and coil.

In this article we will discuss what they are, how they work, and how to perform fan coil unit maintenance.

Trosten Industries Company LLC., located in Dubai, UAE provides Eurovent Certified Fan Coil Units with UL recognized motor components for your interior spaces.

Preventative maintenance helps avoid many of the common problems associated with FCUs. These can include failing to cool or heat the room, removing dirty air filters and coils, fixing thermostat problems and checking for clanking noises while the unit is operating.

Listed below are some general tips on fan coil unit maintenance

  1. Make sure to follow proper lockout and tagout procedures by ensuring the unit is disconnected from the main power supply and that the circuit or fuse has been properly tagged so that no one accidentally turns the unit on while it is being serviced.
  2. The inside and outside of the unit should be inspected to remove any visible debris and dust, especially from the motor and fan blades. Dust collected on the blades can cause the unit to become unbalanced and cause excessive wear and tear to the fan as well.
  3. Removing the filter and replacing it is the key. This helps ensure that the fan coil unit has proper airflow and that small particles like dust, dander and pollen are being removed from the indoor air.
  4. Add lubrication of the oil tubes if your unit has one and ensure that all moving parts are lubricated so they will not be exposed to excessive heat. If you do not have oil tubes, consult your operating manual for the proper procedures on lubrication.
  5. Close and seal the unit and test its operation after the maintenance procedure is completed.

Fan coils vs. heat pumps: What is the difference?

 Fan coils and heat pumps are both HVAC systems used to regulate the temperature and air quality in buildings. Both have their unique advantages and disadvantages, and the choice between the two will depend on the specific needs of the building and its occupants.


Fan coil units (FCU) are typically used in multi-unit buildings such as apartments or office buildings. They consist of a coil and a fan that work together to circulate air throughout space. The coil is filled with a refrigerant, which absorbs heat from the air passing over it. The cooled air is then circulated back into the room via the fan. FCU is often used in conjunction with a central AC unit, which cools the refrigerant in the coils. In locations like hotel rooms and office buildings, HVAC systems are frequently adjusted using a fan coil unit. It produces more cooling and heating while taking up less space.


One major advantage of FCU is their ability to provide precise temperature control in each unit. This is particularly useful in multi-unit buildings, where different occupants may have different temperature preferences. Additionally, fan coils are simple and easy to maintain, making them a cost-effective option for buildings with multiple units. Better indoor air quality can be achieved by reducing the growth of mold, viruses, bacteria, and other pollutants in the air by using FCU. They can assist in reducing your energy bills by working in conjunction with your heat pump.


Heat pumps, on the other hand, are used to both heat and cool a space. They work by absorbing heat from the air or ground outside and transferring it into the building. In the summer, the process is reversed, and the heat pump removes heat from the building and releases it outside. Heat pumps are often used in single-family homes and small commercial buildings. Due to their continuous use for heating and cooling throughout the year, heat pumps' lifespan can also be greatly shortened, which will increase the cost of HVAC equipment service and maintenance.


One major advantage of heat pumps is their efficiency. Because they transfer heat rather than generate it, they use significantly less energy than traditional heating systems. Additionally, heat pumps can also provide hot water, further increasing their efficiency and can be used in a variety of climates, from extremely cold to mild.

If you need FCU for your building, contact Trosten team, a recognized and reliable HVAC products supplier in the UAE and all products are manufactured in their state-of-the-art facility.

Importance of ventilation in indoor air quality

 Modern homes are becoming more and more energy conscious. We have blocked chimneys, insulated, draught-proofed, double-glazed, and gradually shut our homes from a necessary source of fresh air to conserve energy. Limitations of ventilation may lead to humidity, which causes moisture and mildew and lowers the quality of the air within our houses.

We must be fully aware of the quality of the air we breathe because we spend 90% of our time indoors. Pollutants produced indoors have an impact on interior air quality, which also relies on the surrounding outside air. Health and well-being are significantly impacted by indoor air quality. It is under stress because of the building envelope's ongoing compression and the addition of several new materials that might release dangerous pollutants. The absence of contaminants that irritate, injure, or harm inhabitants is a common definition of good indoor air quality.

Enough air must be pulled in and dispersed to ensure that it covers every part of the house to offer good air quality. Windows and structural components let practically all dwellings let in the fresh air. To increase the flow, many homes feature additional HVAC Equipment. A specific ventilation unit is required for some sources, such as restrooms and stoves, to eliminate the pollutant they produce. To prevent dispersing airborne contaminants from cooking within the house, the ventilation unit above the stoves must move the air outdoors.

Ventilation units aid in lowering indoor air pollution, however, they are most effective when used in conjunction by excluding identified sources of pollutants from the structure. For instance, smoking is not permitted inside or close to entrances, which is the only way to lessen the effects of passive smoking indoors.

Here is how poor ventilation can affect your health and living conditions:

  • Indoor pollution accumulates when there is not enough airflow. Occasionally attempts to make structures more energy efficient might backfire by preventing adequate air from moving, causing pollutants to accumulate.


  • Homes with inadequate ventilation may have elevated levels of radon, which can result in lung cancer.


  • High outdoor humidity can increase interior humidity, which raises the possibility of moisture damage inside, including the formation of mildew or wood rot.
