Your HVAC system is the primary method of climate control in your home and works to maintain the comfort levels within the interior of your home no matter what the exterior conditions are like. However, year-round operation can take a toll on your HVAC system, which means that it is likely to begin to malfunction after it has aged for several years. Understanding some of the early warning signs associated with an HVAC system that has started to go can help you determine when you should get in touch with a contractor to consider replacing your heating and cooling units.
1. Loud Noises
While a certain amount of noise is normal when your HVAC system is operating, you should keep an ear out for any loud and constant noises, especially ones that have an irregular bent -- like grinding or screeching that is caused by metal on metal. This can point to damaged internal components which are rubbing up against other pieces of your HVAC system. This is more than an annoying problem that will wake you up in the middle of the night: constant rubbing and friction can cause additional wear and tear that can make a complete unit failure much more likely.
2. Uneven Climate Control
Another common sign that your HVAC system is on its last legs is if you notice that the heating or cooling in your home is no longer even. The existence of hot or cold drafts, or particular areas that just don't seem to be affected by the climate control of the system, all point to improper and inefficient operation. You may also notice that there is little airflow coming out of the vents: this can be because of blocked ductwork, which will require a professional cleaning, or because of a damaged or broken fan and blower system, which is more likely to require replacement of your HVAC units.
3. Increased Energy Bills
Finally, one of the last and less obvious signs that your HVAC system is no longer working as intended is if you find that your energy bills are skyrocketing each month. This is usually because your HVAC units are no longer able to heat or cool your home efficiently, forcing them to work longer to maintain the same temperature that they were able to easily meet beforehand. This can spike your utility bills and can make replacement a financially sound decision by cutting the monthly costs of operating your climate control system.
