Frequently Asked Questions — Furnace Maintenance & Winter Prep in Lake Charles
A tune‑up ensures your system will heat reliably when temps dip. Technicians can clean and inspect critical components like burners, heat exchangers, filters, and safety controls. It’s essentially preventative maintenance to avoid breakdowns and lower monthly bills.
If you use a standard 1-inch disposable filter, swap it monthly during heating or cooling seasons. Thicker or media filters can last 3–6 months, depending on dust, pets, and usage.
Absolutely. DIY steps include:
-
Changing or cleaning filters every 1–3 months
-
Cleaning vents and returns
-
Clearing clutter from around the furnace
-
Testing thermostat settings
These are safe, straightforward, and keep your system efficient. However, if you suspect that you need a repair or replacement - please do not mess with your HVAC system alone. Call S&S HVAC immediately to keep yourself and your family safe.
Watch for:
-
Strange noises (rattling, banging, whistling)
-
Unusual odors (burning, musty)
-
Inconsistent heating or short cycling
-
Rising energy costs despite normal usage
These can indicate worn parts or airflow issues.
Plan for at least one professional check-up annually—ideally in the fall before winter—or even twice a year (heating and cooling seasons) for peak efficiency and reliability.
Most furnaces last 15–20 years. After that, efficiency drops and repairs become more frequent. Lake Charles homeowners should begin budgeting for replacement once the unit hits around 10 years—and consider full replacement by year 20.
A thorough professional check-up generally covers:
-
Visual and safety inspections
-
Cleaning internal parts and checking airflow
-
Testing for gas or carbon monoxide leaks
-
Tightening electrical connections, lubrication of moving parts
-
Testing start-up sequence and thermostat accuracy
Yes. Well-maintained units run more efficiently, reducing energy use and utility bills. Preventing breakdowns also avoids costly emergency repairs—and can extend furnace lifespan.
Indeed. Most often, people:
-
Skip changing filters
-
Block air registers with furniture or rugs
-
Ignore early warning signs like odd noises or smells
- Skip seasonal tune-ups
Avoiding these mistakes goes a long way toward efficient, trouble-free heating.
