It's simple to give your heating and cooling system very little thought. It never stops, making sure that the temperature in your house or workplace is always comfortable. But you know how everything comes to a screeching halt when you have a problem? No, not always. Your system may exhibit some very tiny but noticeable issues as a warning that maintenance is urgently required.
Loud, Unusual Noises
Squealing, grating, or grinding noises indicate that something is wrong with your system. These noises could signify a problem with the motor, an absence of lubrication, or the misalignment of a component. This article from Angie's List provides a list of additional strange noises that your HVAC assemblies shouldn't make, such as repeated clicking or shrieking. Additionally, if you hear a "thwapping" sound, there might be a blower issue. Unattended use could cause the motor to deteriorate.
Strong or unpleasant odors coming from your HVAC system are typically indications of a deeper problem. One of its components may have burned through the wire insulation. Or, if the air conditioner has a musty odor, this may be a sign that there is mold growing inside the device or its ductwork. In either scenario, you must immediately make a service request.
Dusty inside of your building
Dominion Power asserts that excessive levels of dust in your house or place of business may be caused by clogged air filters or leaky ducts. This issue can probably be resolved by changing the filters and repairing the ducts, but if it persists, you'll need to contact a specialist in heating and cooling maintenance.
Uneven distribution of temperature
It's likely a sign of poor air movement if some rooms in your home or place of business are excessively hot or chilly without your intentional involvement. Only a qualified HVAC professional can now accurately identify and resolve the problem.
Not Enough Cool Air
Even if you run your AC at full capacity, it either doesn't turn on or doesn't provide any cool air. It's possible that your compressor or thermostat is acting up, or that your unit's Freon levels are low. It's a malfunction that calls for assistance from an HVAC expert in any scenario.
The age of your HVAC system exceeds 15 years.
The average HVAC system can operate effectively for 15 to 20 years. After then, you ought to think about switching it out for a new, more energy-efficient model. Even if you are not currently having issues with your heating or cooling, it would be beneficial to replace your HVAC assembly every ten to fifteen years. According to the US Department of Energy, upgrading to a more modern system may allow you to cut your energy bills by anywhere between 20% and 40%.
It might be best to request assistance right away.
Your HVAC system's minor issues may develop gradually over time or emerge suddenly. However, little annoyances can quickly escalate into serious problems until your heating and cooling quit functioning altogether. Before your system entirely fails, keep an eye out for warning signals of impending failure and make sure you have a trustworthy, qualified HVAC technician you can call.
