Heating Issues Charleston Homes 2025 - What To Do

As temperatures continue to dip here in the Charleston area, your home’s heating system will take center stage in keeping your family comfortable this fall and winter.

 

 

 

No matter if you have a traditional furnace or ductless heat pump that keeps your family warm, it’s the time of year when it will be tested the most.

 

 

 

Switching from cooling to heating can stretch many HVAC systems this time of year, but with lows consistently sticking around your heating equipment will be also be operating more consistently.

 

 

 

With that additional usage rate, issues can naturally occur more often.

 

 

 

If you find yourself in a cold situation this fall and winter, here are a few areas that could be the culprit of your issues.

 

 

 

1. Primary Unit Issues

 

 

 

Especially for HVAC systems that are older or have had frequent repairs in recent years, there very well could be an issue within your primary unit.

 

 

 

Whether you have a traditional furnace system or a ductless heat pump, there could be issues happening inside this primary piece of equipment that will need to be addressed.

 

 

 

The source of the exact issue within your primary HVAC unit will have to be diagnosed and repaired by a professional, but could be any number of items.

 

 

 

2. Air Handler Issues

 

 

 

For those with traditional heat pump units, the source of the issue could be the air handler.

 

 

 

The air handler – as the name implies – pushes and pulls the air throughout your home’s ductwork.

 

 

 

Even if your primary unit is working properly, if the air handler is running into issues, heat won’t flow throughout your home.

 

 

 

3. Thermostat Issues

 

 

 

The HVAC systems’ control mechanism, your thermostat could also be the source of the issue.

 

 

 

From not turning on (or not turning off) and other issues, thermostats can be the heart of your heating woes.

 

 

 

Your Local HVAC Company Will Have The Best Diagnosis

 

 

 

While the three items listed above are likely sources of the heating issues in your Lowcountry home, a professional heating & air conditioning contractor will be best equipped to hunt down and correct any lingering issues.

 

 

 

DIY HVAC fixes may result in more issues – some more costly than others – so having an HVAC technician address them is the best bet to getting your family living more comfortably again in the Charleston area.
