Trane: Classic Charleston, Modern Comfort

Charleston, like much of the South, is a city steeped in heritage, culture, and history—a fact which is nowhere more evident than in its architecture. Sweeping historical mansions stand alongside modern brick condo buildings, their contrasting styles revealing Charleston’s past and present in a single streetscape. Despite these differences, these homes share a common challenge: maintaining comfort—from hot, humid summers to the mild chill of winter.

The Humidity Factor

Why keeping a Charleston home comfortable means managing moisture, too

  Humidity can be sneaky, making indoor air feel damp and sticky—even when the thermostat shows a reading of what should be a comfortable temperature. In Charleston, humidity is both legendary and persistent, even during cooler weather. Beyond affecting comfort, this also affects flooring, furnishings, decorative materials, and even door frames. Managing a home’s humidity levels is crucial to protecting the integrity of its interior.

    “Properly sized and professionally installed HVAC equipment helps to remove excess moisture from the air while maintaining comfortable temperatures,” says Trane Account Manager David Sipple.

    Sipple goes on to explain that while a conventional single-stage system runs at full output, shuts off at temperature, and starts again when needed to re-cool the space, variable-speed systems like Trane’s 20 TruComfort Variable Speed Heat Pump with WeatherGuard adjust their output to match changing conditions. By running longer at lower speeds, these variable-speed systems help maintain comfortable temperatures as well as humidity levels.

    Paired with compatible Trane variable-speed equipment, the Link UX360 Thermostat’s enhanced dehumidification capabilities work as part of a connected system that responds to indoor conditions. Using the Trane Home app, homeowners can also monitor and adjust system settings remotely.

    Naturally, factors such as equipment size, ductwork, layout, and installation quality affect results, so homeowners should always inform HVAC professionals of any rooms prone to damp conditions or uneven temperatures. “Humidity control starts with proper system design,” says Sipple.

One System, Four Seasons

Changing the conversation about heating and cooling all year long

 Heat pumps, despite their name, actually provide both heating and cooling—a fact which greatly benefits Charlestonians during the area’s long, humid summers as well as its winters. Simply put, during summer, the system moves heat from inside the home outdoors. The process reverses in winter, pulling heat energy from outdoor air and transferring it inside. 

​Trane’s 20 TruComfort Variable Speed Heat Pump with WeatherGuard offers this ability while also featuring a protective WeatherGuard top, providing protection for outdoor equipment by keeping sand, rain, and other debris away from critical components and safeguarding the system’s inner workings. Additionally, the system’s ability to increase output during the heat of summer and operate at lower speeds during milder weather helps reduce noticeable temperature swings and improves energy efficiency. 

 Sipple notes that the needs of every home are different. Homes with existing ductwork may be more suited to a traditional ducted heat pump, while in cases where adding ducts would be difficult or require extensive construction, ductless mini-splits are an effective option to provide targeted heating and cooling. “That’s why it’s important to work with a local HVAC professional or Trane Comfort Specialist to determine whether a high-efficiency air conditioner or heat pump is the right fit for your home and lifestyle,” Sipple says. “The key is matching the solution to the home.”
