A failing furnace or air conditioner isn’t a fun situation. There are usually signs that an HVAC is failing, like increased humidity, an odd smell, or changes in power, but what causes them? If you’re noticing issues with your heating or cooling, it’s wise to reach out to an HVAC repair contractor for repair.

Before you notice signs of an HVAC issue that would require repair or replacement of the entire system, you can be proactive and be aware of problems that might be causing your HVAC system to fail. Doing so can prevent you from dealing with significant issues later on!

Leaks

Have you noticed any liquid pooling or dripping from your system? Leaks signal a problem of a failed expansion joint. You might not even be able to see leaks, either, so it’s wise to pay attention to issues like:

  • AC air that seems warmer than usual
  • Ice forming on the lines of your AC
  • Higher electric bills
  • Poor airflow

Drainage

When the condenser fails on your AC, you’ll notice pools of water. You’ll want to address that concern immediately since it will cause water damage to other areas of your home.

Pilot Not Lighting

Is your furnace pilot light not igniting? There are a few reasons for this, like a gas supply issue, short cycling, or worn components preventing ignition. Either way, it’s best to call an HVAC professional to handle any pilot light problems.

Clogged Filters

But not every cause of an underperforming HVAC system is a professional problem. Clogged air filters will make a system work harder and undue strain on all the components working to force air into your home can often be overlooked. Be sure to change air filters every six months.

Electric Controls

Your home’s HVAC system works hard year-round, and electrical wires can begin to fray, wear out or become loose. If you ever notice your system hiccupping as it starts up, the occasional shutdown, or burning smells, worn-out wiring is to blame.

Most problems that might be causing your HVAC system to fail should be handled by a professional! But keeping an eye on how it’s performing can help you stay on top of any concerns and, hopefully, prevent any major repairs or a complete replacement.
