Enjoy a Cool Summer with a Perfect HVAC System

With summer season round the corner it is important to check the effective functioning of your heating and cooling system so that it provides a comfortable environment. It is a good idea to schedule a professional service who can guide you with various tips on how to perform a regular maintenance of your HVAC system or tell you if any of the heating and cooling parts need an upgrade with new coils or new parts.

Checklist of items of your HVAC System

Here are some of the pointers to keep in mind when you hire a professional service and check if they inspected the important parts before they wrap up.

• One of the important parts to be checked while evaluating the efficiency of your HVAC system is the condenser coil. Over a period of usage your condenser coil may not work as expected. For instance, even after setting your thermostat level to provide an optimal cooling temperature if the room feels warmer then it is time for an upgrade or replacement of your condenser coil.
• The next crucial factor to be checked is the evaporator coil. In general, the coil leakage is the one of the common problems found in the evaporator coils. This can be easily identified if your refrigerant level is too low than the normal range. 
• Some of the reasons of the coil leakage are rust and corrosion build up in the building parts which are unavoidable in certain situations. 
• In some of the HVAC systems, chilled water coils are used for a comfortable and energy efficiency cooling method and also used for dehumidification. But in winters these chilled water coils may tend to freeze in extreme winter conditions. Thus, proactive measures help to prevent these coils from freezing. 
• However, diligence care should be taken while installing these chilled water coils for longer durability like measuring the height of casing accurately, determining the number of rows and the fins and so on. 

Thus, it is important to keep your HVAC parts up and running to give you a cool summer season.

Condensing Units and Its Types

Condensing units can be categorised into three types namely water, air and combination of both air and water based on how the heat is removed from the condensing unit. Let us see briefly about each type.

Air Cooled Type

This type of air-cooled types is used in small companies and for household applications. Air cooled are suitable for low capacity which is under 20 tons only. There are several benefits in using air-cooled condensing type units like it does not require a separate water piping units or water disposal system. This type is economical, and it will not have any scaling issues which is caused by some mineral deposits. Easy to install and it gives less initial set up cost. Thus, the overall maintenance expenses are much less when compared to other types of the condensing unit. However, these air-cooled type has few disadvantages as well. For instance, the compressor lifetime is relatively short that is when more cooling is required, it will not be available or sufficient. Also, it needs high power per ton of refrigeration.

Water cooled Type

Water cooled type is another form of condensing unit which further is sub divided into three categories which are ‘shell and condensing coil’, ‘double tube’, and thirdly ‘shell and tube’. The most widely used model among these three categories is shell and tube type. These are available from as low as two-ton capacity to a higher capacity of two or more hundred tons. This is possible by the unique design of the model which requires only a little power consumption per ton of refrigeration and also the compressor has a longer lifespan when compared to a previous model that is the air-cooled type. For a high capacity application, a water-cooling tower is generally used.

Evaporation Type

This evaporation model is a mixture of water- and air-cooled type condensing units. Thus, in all these types the air blows through an effective condenser coil for these conducting units which in turn transfers the heat into the outdoor air. The presence of a high-pressure liquid refrigerant makes the condenser coil to make a U-turn, and it reverts to the evaporator coil.
