When to switch from cooling to heating mode – guidance for Sheffield homes

Have you ever wondered exactly when to switch from cooling to heating mode as the seasons change in Sheffield? It’s a question many homeowners ask when autumn approaches, and it can make a real difference to both your comfort and your energy bills. As your trusted air con installer in Sheffield, we’re here to share some expert guidance to help you get the timing right.

 

Why timing matters

In Sheffield, temperatures can swing quite quickly. One week you might be relying on air conditioning to keep the house cool, and the next you’re reaching for the heating controls. Switching too early can mean unnecessary energy use, while waiting too long can leave your home feeling damp and uncomfortable.

It’s all about balance. Knowing when to change from cooling to heating isn’t just about comfort; it also affects the efficiency and lifespan of your system.

 

Signs it’s time to switch

So, how do you know when the moment has come? Here are a few tell-tale signs:

  • Consistent overnight chills – When the evenings dip below 12°C, it usually signals the start of heating season.
  • Feeling damp indoors – Autumn brings higher humidity, and heating helps to keep condensation under control.
  • Energy efficiency drops – If you’re running the air conditioning but constantly reaching for a jumper, you may be wasting electricity.

As a rule of thumb, once daytime highs are around 15°C or lower, it’s sensible to start heating instead of cooling.

 

The best way to manage the switch

If your system has both heating and cooling modes, make sure the settings are correct before the weather turns. Switch your thermostat over to heating mode, and test it on a mild day to check everything is working as it should.

This is also the ideal time to book a professional service. A seasonal check ensures your heating system is safe, efficient and ready for use. Our qualified engineers can carry out full servicing at transparent rates – you can view our prices here.

 

Common mistakes to avoid

Many homeowners leave their system in cooling mode for too long. This can cause strain on your unit and waste energy. Another common issue is switching modes back and forth within a short time frame, which can wear out components unnecessarily.

Instead, wait until you’re sure the cooler weather is here to stay, and then make a one-off switch.
