Every year, thousands of people in the United States develop temperature-related illnesses. Extreme heat and cold events even claim hundreds of lives each year.
Those figures could be higher if not for heating, ventilation, and air conditioning.
That’s why it’s vital to ensure your system is always in top condition. For the same reason, it’s imperative to learn the signs you need professional HVAC help.
Don’t worry, as that’s what you can learn in this guide. So, read on to learn the signs and what to do about them.
1. Inconsistent or No Heating or Cooling
Check your air filters first if you’ve noticed weak airflow from your HVAC system. They might have become so filthy they no longer let adequate air pass through them. If they’re dirty, wash or replace them immediately.
Next, make sure nothing obstructs the supply ducts or return vents. For instance, someone may have pushed a piece of furniture too close to these openings. Another family member might have also closed them if they felt too warm or cold.
If your system still doesn’t heat or cool enough after taking those steps, it’s time to look for a pro near you. You can start by researching your options and checking out online ads for HVAC companies. You can check out this link to learn more about such advertisements.
2. Weird or Foul Smells
Filthy air filters can again be the culprit behind an HVAC system producing foul smells. After all, these components trap all sorts of pollutants, such as dust, molds, pet dander, and dust mites. So, if your conditioned air smells funky, be sure to check and wash or replace the filter.
If you smell something like burning plastic, please turn off your system ASAP. That odor can indicate melting and damaged HVAC wires. After powering it off, call an HVAC repair company offering emergency services.
Do the same if your natural gas furnace emits smells akin to rotten eggs or sulfur. That’s a sign of a gas leak, which, in some situations, can lead to an explosion.
3. Sudden Loud and Obnoxious Noises
A hissing noise from a furnace is likely due to a leaky air duct. That sound often comes from the air trying to force itself out of a tiny crack or hole in the ductwork.
Turn off your air conditioner if it’s producing a loud hissing or whistling noise. That can indicate leaking refrigerant, which can lead to poisoning.
Likewise, power off your HVAC if its outside unit seems to be screaming. That signals an overheating or malfunctioning compressor.
You should also turn off your HVAC system when you hear loud banging or clanging. That’s often a sign of a loose component or a foreign object continuously hitting the fan. Unless you power off the unit, it might keep ricocheting and causing severe damage.
After that, your next best bet is to call a pro to inspect and repair or replace your broken HVAC system.
