Tips for Improving The Cooling Efficiency Of Your HVAC System

Just like other mechanical devices, air conditioning systems are prone to operational inefficiencies meaning regular maintenance checks are necessary. Some of the maintenance checks you should undertake to improve the cooling/chilling efficiency of your HVAC unit include:

Water treatment

The majority of HVAC units use water to keep building spaces cool (heat transfer). For this reason, it is advisable to make sure the water that runs through your HVAC system is properly treated to prevent corrosion, scaling, or biological processes that could lead to mold/mildew growth. If your HVAC unit is based on an open-water system, the rule of thumb is to ensure continuous water treatment. On the other hand, water supplied to HVACs based on closed-water systems can be chemically treated once. Furthermore, make sure you clean parts like water strainers and sand filters at least once every three months. If you fail to do so, scales and sand particles could clog your HVAC’s chiller reducing its efficiency.

Oil and refrigerant checks

Once every year, check the oil and refrigerant in your HVAC. It is also wise to carry out a spectrometric chemical analysis to determine the level of acids, metals, water/moisture, as well as the presence of contaminants. Since this is a highly technical task, hire a well-equipped chemical lab to undertake spectrometric analysis. If results are less than ideal, replace the oil. At the same time, check oil filters and replace them if they show signs of wear and tear. 

Compressor leaks

It is advisable to have a qualified technician test your compressor for leaks at least once every four months. This is because it is technologically impossible to design and manufacture a perfectly sealed compressor unit. As such, a compressor could have small gaps that allow in air and moisture. If you are looking for a quality company to rely on in this area, one of the best is HVAC Construction, Inc. Some industry experts reckon that air pressure loss of about 1 psi reduces HVAC chiller efficiency by three percent. 


If your air conditioning unit’s chiller components do not work properly, its

Efficiency will definitely be sub-optimal. To ensure this does not happen,

Treat the water that flows into your HVAC system to prevent problems such as corrosion and development of scales. In addition, hire a qualified chemical lab technician to undertake spectrometric chemical analysis once annually.
