The Most Common HVAC Problems

by Mary Hahn

Ever since HVAC was invented, this machine provided a great contribution to many countries around the world, including Australia. The kind that this technology makes in promoting indoor air quality is superb that suppliers definitely experience incredible sales. For households that need heating and cooling Melbourne has a lot of companies which can satisfy this need.

But even though HVAC machines are beneficial to everyone, it’s not immune to damages and expensive repairs when not properly taken care of. Without the right maintenance, ignoring the problems can cost thousands of dollars for repair. Therefore, it’s extremely important for owners to know the most common HVAC repairs and what should be done when these problems are observed.

Malfunctioned Circuit Breaker

A blown fuse or tripped circuit breaker can trigger your HVAC to malfunction. It can be caused by a problem to the system. To address this, always check for any blockages on the airflow or assess the air filters.

System blockages can lead to an overworking blower and these can be due to dirty air filters. Other causes may also include duct leaks, dirty coils and blocked air registers. Take note that you need to replace the dirty filter first before repairing the circuit breaker.

Malfunctioning Thermostat

There have been many cases where the HVAC is less functional not because of the unit itself, but due to the thermostat. This can be due to causes such as low battery or the heat has not been activated.

Fortunately, if the problem is detected earlier, you can simply check the settings. Replacing the battery will also solve the case.

It’s also highly recommended to read the manual prior to first use to save yourself from an expensive service charge. If the problem still persists despite applying these solutions, call your technician.

Water Leakage

Just like the water cycle, condensation is also part of the HVAC cycle. The system produces condensate which is then drained through drain pipes. However, if the drainage isn’t functioning properly, this can lead to water leaks.

Clogged pipes are actually one of the most common HVAC problems. This is where the condensate starts to overflow out of the drain line. To prevent this problem, you can pour bleach down the pipes.

Other causes of water leakage include cracked pipes and malfunctioning evaporator drain, collector box and heat exchanges. HVAC technicians usually address this problem by first cleaning the pipes prior to identifying the source of the leak.

Reduced Efficiency

Have you experienced cases where the room is no longer that warm or cool as before? If this happens, you need to have a checklist of possible problems.

First thing to do is to check the filters since it’s the most common cause of reduced efficiency. If you can do it yourself, you can change the filter. Aside from the fact that it’s easy, it saves you money from hiring someone to do it for you.

Reduced efficiency can also be caused by blockages. If this is the case, try to locate the blockage and clear it to regain the efficiency of your HVAC. But if your machine’s components are already dirty, it’s best to contact a professional to clean the entire system with the use of a special cleaner.

Other problems you may experience with HVAC include unusual noises, continuous running of the blower and leaks on the refrigerant. Always remember that if you’re hesitant on fixing the problem yourself, the best method is to contact a technician to do it for you.
