Are you feeling too cold or too hot lately? When it comes to maintaining optimal indoor temperature, the HVAC system plays a vital role. The heating, ventilation, and air conditioning (HVAC) system is used to provide heating and cooling to residential and commercial buildings. This system is responsible for ensuring indoor comfort by maintaining thermal control and heat transfer. The heating and cooling system used in homes is also known as the HVAC system. There are different types of HVAC systems but the purpose of all systems is to keep you and your family comfortable all year long. Any problem within this system could lead to an uncomfortable indoor environment, poor indoor air quality, and even allergies.
HVAC system performs a crucial function yet many homeowners don’t take care of their heating or cooling system—until something goes wrong. To keep the system properly during extreme summers or chilling winters, regular maintenance is incredibly important. Periodic maintenance at least twice a year, once for heating in winters and once for cooling is highly recommended. But often homeowners neglect maintenance and minor issues that result in serious problems. So, to avoid costly repair and replacements, it’s best to identify signs of HVAC malfunction and take prompt action. Here are some signs that indicate you need to hire an HVAC repair service to avoid serious trouble.
Sudden Increase in Energy Bills
It is normal to notice an increase in energy bills during the extreme winter or summer season when your heater or air conditioner works consistently. However, if recently your bills have become way more costly than usual then possibly there’s an issue. Electricity cost goes up when your HVAC system isn’t working as efficiently as it should. High bills are often a result of dirty air filters, duct leaks, or failing parts. So, to avoid paying high utility bills, it makes sense to schedule a tune-up. A qualified HVAC repair specialist can fix duct leaks and ensure proper working of motors, capacitors, and the compressor.
Change in Airflow
Another common sign of malfunctioning HVAC is airflow issues. Hot and cold spots in your home indicate a failing HVAC system. Also, if your air conditioner isn’t cooling as it used to be then you need to get it serviced. When AC becomes slow or you notice any change in airflow, then possibly the compressor is malfunctioning. Insufficient cooling could also be a result of a failing or damaged fan. Ignoring this problem for too long will put pressure on your system and may even cause compressor failure.
Odd Noises and Smells
Any strange noise- clanking, banging, or rattling is a clear sign of a damaged HVAC system. Sometimes, air conditioners make funny noises that can become annoying over time. Avoiding these sounds can be a big mistake because your system might need belt repair or motor replacement. Likewise, any smell means your system needs maintenance immediately. Ignoring an odd noise or smell for too long may worsen the problem and cause a sudden breakdown. Addressing minor issues on time helps in saving money on expensive replacements.
The System Keeps Turning On and Off
Your HVAC unit could exhibit various signs of damage- odd sound, water leak, inefficient cooling, or frequent turning on and off. When the system constantly goes on and off, it means there is some problem with the thermostat. There could be several other reasons also for AC turning on and off in short intervals such as iced or dirty evaporator coil or clogged air filter. Sometimes, simply cleaning the condenser unit, fan, or evaporator can fix the issue. However, to find the exact cause of the problem, call a HVAC professional for repair service.
