Heating Maintenance is Particularly Important in South Carolina

Living in Charleston means dealing with some pretty unpredictable weather. One minute it’s mild, and the next, we’ve got a cold snap rolling through. Your heating system takes the brunt of that, working harder than you might think, even in our mild winters. That’s why staying on top of repairs and regular maintenance is key. If you wait until something breaks, you’re risking not just discomfort, but a bigger repair bill down the road.

Plus, let’s not forget about the coastal humidity. That salt in the air can do a number on your system over time. Corrosion happens quicker around here, especially in parts that might go unnoticed. Routine check-ups help us catch those issues early, saving you from an unexpected breakdown when you need your heater the most. A well-maintained system is going to last longer and run more efficiently, which means lower energy bills and fewer headaches for you.

Facts and Case Studies

“By combining proper equipment maintenance and upgrades with recommended insulation, air sealing, and thermostat settings, you can save about 30% on your energy bill while reducing environmental emissions.” ~ Energy.gov

“Modern furnaces—especially high efficiency models—are more complicated than models from decades ago. The efficiency gains are due in large part to the careful balancing of fuel, combustion air, and exhaust gasses. The management of these systems is accomplished through electronic controls, which need periodic adjustment and cleaning for optimum performance. An annual clean and tune of the furnace will keep the systems properly adjusted, and potentially reduce costly future repairs.” ~ MN.gov

“Research has shown that the performance of existing residential and small-commercial heating ventilating and air-conditioning (HVAC) systems is far from optimal. In many cases, the systems were never installed correctly and have never operated optimally, resulting in lower efficiency than implied by the nameplate rating. In other cases, the performance has degraded over time, either because of faults or improper service, causing the equipment to malfunction or to perform poorly. Measures such as duct sealing and repair, condenser and evaporator coil cleaning, refrigerant charge and air flow adjustments, economizer retro-commissioning, and HVAC controls can potentially produce significant savings” ~ CARMAC.org
