5 Common Myths About HVAC System Services

Information arms you with the power to make smart decisions. However, not every type of information is trustworthy. False information can lead to problems due to poor choices, although its effects are likely to become noticeable only down the line. Confounding the problem with misinformation is its ready availability. False info and fake news are everywhere. Many people even insist on myths, making them completely and willingly oblivious to the truth.

Homeowners often fall victim to these myths, especially when it comes to HVAC equipment care and function. Unfortunately, these HVAC service myths not only lead to poor decisions, but they also tend to be damaging and ultimately, costly.

5 Common Myths Regarding HVAC Services

Certain myths persist to this day about HVAC services. To help you get around this potentially problematic information, we have outlined the most common myths you need to avoid.

Myth #1: You Only Need To Replace The Air Filter Once Every Year

Why this myth exists is still a mystery. However, its persistence is probably due to the fact that many HVAC air filters are high-efficiency types. There is a mistaken belief that they are so efficient that they only need an HVAC air filter replacement once each year. The truth is that air filters need to be checked and changed every one to three months to keep them reliable.

Air filters can have a significant impact on indoor air quality. Filters trap particulates such as dust, pollen, pet hair, dander, and other types of airborne particles. Without air filters, it will be quite difficult for you to breathe easily. Filters also help reduce the risk of respiratory diseases, allergic rhinitis, asthma, and other related conditions. They do, however, become clogged and when they do, they either need to be cleaned or replaced. Clogged filters also contribute to poor airflow, which significantly reduces your comfort level and system’s efficiency.

Myth #2: A Bigger Sized HVAC System Is Always The Best Choice

Well, not always. A big HVAC system does not always equate to the best performance. Many homeowners think that just because a hearting or cooling system is large means it will give the best service. This is largely due to the common belief that the bigger the HVAC system, the more reliable it is.

Although size does matter when it comes to HVAC systems, bigger systems are not always the best choices. Installing an AC unit that is too large for a small-sized home, for example, will only cause the system to short-cycle, which will ultimately lead to premature wear-and-tear. The system will also fail at reducing the amount of humidity indoors.

To ensure that your HVAC system works as it should ask an HVAC professional to perform a proper sizing of your home. The correct HVAC system size will perform optimally, so it is unlikely you will need a unit replacement soon.

 

Myth #3: HVAC Maintenance Is A Waste Of Time

Here’s a myth that can do more harm than good. Waiting until your HVAC system is damaged or broken before calling an HVAC technician is never a good idea. All HVAC systems come with specific maintenance requirements that manufacturers recommend. This is to ensure that the system functions optimally and does not become subjected to premature wear-and-tear.

If you wait too long to call a professional and something has already been broken or damaged, the repair work will likely be quite costly. Keep in mind that preventive work saves money. Therefore, getting your system inspected regularly helps you avoid frequent repairs.

If your system is still under warranty, the manufacturer might refuse to accept the coverage if their recommended maintenance schedule was ignored. To keep the warranty and/or ensure that your HVAC system is at its best form, have your local HVAC technician perform tune-ups at least once a year.

Myth #4: Spotting Air Leaks Is Easy

No, it is not. Air leaks are invisible and unless the leak is substantial, you likely will not be able to locate it using your senses. Air leaks lead to system inefficiency. If there are cracks, holes, and gaps in the ductwork, for example, warm or cold air can escape, affecting the ideal temperature indoors. To compensate, the HVAC system will have to work harder and thus consume more energy.

Air leaks are difficult to spot. The best way to find them is to ask an HVAC professional to perform an energy audit and check your home for possible sources of leaks. HVAC technicians are trained to perform a thorough inspection and have the right tools and equipment for the job.

Myth #5: The Thermostat Is A Reliable Temperature Controller

A thermostat is designed to sense temperature indoors. It will then send a signal to the HVAC system to regulate the heat or cold. Simply set the desired temperatures and the thermostat will take charge. Unfortunately, it is not always this perfect.

Although thermostats are usually reliable, they could also produce the wrong reading and thus create indoor conditions that are less than ideal. If the thermostat is installed next to a window, for example, it might receive too much heat from the sun. This will cause the sensors to generate false temperature readings which in turn will affect how the system performs.

If your home suffers from serious air leaks or insufficient insulation, your HVAC system will fail at reaching the ideal temperature setting. If you want optimum performance and reliable comfort, work with a trusted HVAC technician to get your thermostat working properly.

 

Conclusion

Myths are invented and become beliefs because some people do not have the proper understanding of how heating and cooling systems actually work. To avoid the pitfalls of HVAC myths, do your research and scrutinize everything. Better yet, ask an HVAC technician from Wilcox Energy for real advice.
