Many homeowners wonder whether it’s safe or practical to run their air conditioning system in Rotherham during the colder months to control indoor humidity in homes or small businesses in Rotherham or the surrounding areas in South Yorkshire.
The quick answer is you can run your AC in winter to dehumidify, but it’s generally not recommended because most air conditioners aren’t designed to operate in low outdoor temperatures; doing so can cause the coils to freeze, reduce efficiency, and potentially damage the system, meaning alternative dehumidification methods are usually safer and more effective during colder months.
At Brookhouse Gas, we regularly help customers across Rotherham assess how their systems can be used year-round. While running an AC in winter can help with dehumidification, there are specific technical and practical points you need to consider first.
How Air Conditioners Dehumidify Your Home
Air conditioners don’t just cool your indoor air—they remove moisture too. When air passes over the cold evaporator coils inside the unit, moisture condenses and drains away, leaving your rooms feeling drier and more comfortable. This process naturally reduces humidity, which can help prevent problems like damp, mould, and condensation on windows.
However, when the outdoor temperature drops significantly during winter, the refrigeration cycle inside your AC system can be affected. The coils may freeze, and the system may struggle to operate efficiently without specialised settings or a heat pump feature.
Is Running AC in Winter for Dehumidification in Rotherham Safe?
If your air conditioning system comes with a built-in “dry” or “dehumidify” mode, you can use it briefly even in winter. These modern systems are designed to manage moisture without significantly dropping the room temperature. However, if your unit is a traditional cooling-only air conditioner, running it in very cold conditions can damage the compressor or lead to ice build-up on the coils.
In Rotherham, where winter temperatures can hover around freezing, the best approach is to check your system’s manual or consult a certified engineer. A professional technician can assess whether your model has a safe low-temperature dehumidification mode, or if you should use an alternative solution like a dedicated dehumidifier.
Alternatives and Energy Efficiency Tips
When tackling indoor humidity in winter, it’s worth exploring options beyond just your air conditioner. Using a heat-pump air conditioning system—one that provides both heating and cooling—is particularly effective. These efficient systems can provide warmth while simultaneously drawing out moisture from your indoor air.
- Use your AC’s “dry” mode rather than the cooling mode when temperatures are low.
- Run short cycles to avoid freezing the condenser coils.
- Ensure your system is serviced regularly to maintain efficiency.
- Consider a properly sized standalone dehumidifier for persistent dampness issues.

Why Winter Humidity Control Matters
Managing humidity in winter is more important than many realise. Overly humid air can make rooms feel colder, encourage mould growth, and even damage wooden floors or furniture. On the other hand, air that’s too dry may cause discomfort. Therefore, achieving balanced humidity—typically between 40–60%—can enhance indoor comfort and protect your home’s structure.
At Brookhouse Gas, our engineers also advise homeowners to make seasonal maintenance a priority. Properly maintaining your unit before and after winter helps prevent performance issues and ensures reliability when the weather shifts.
