How to Switch from Air Conditioning to Heat?

As we experience the changing seasons, maintaining a comfortable temperature in our homes becomes a dance between heating and air conditioning. However, constant switching between the two can put unnecessary stress on your heating & cooling systems, resulting in increased energy costs.

From understanding the symbols on your AC to learning when the perfect time to switch is, this guide will cover everything you need to know about transitioning from air conditioning to heating and vice versa.

What You Need to Know When Switching Between Heat and Air Conditioning

There’s more to switching between heating and cooling than simply pressing a button on your thermostat. You should ensure that your air conditioning unit and heating unit are prepared for the change.

Regular maintenance, such as checking the air filter, blower motor, and the overall condition of your heating systems, can help you make a smooth and energy efficient transition.

Downsides of Switching Between Heat and Air Conditioning

While switching between heat and air conditioning is necessary as we cycle through the seasons, it can sometimes lead to problems such as moisture buildup in your heating and cooling systems, or unnecessary stress on the blower motor. Moreover, frequent changes in temperature settings can also lead to spikes in energy bills.

Can You Turn on Heat with the AC?

Typically, you cannot use your air conditioner and heat pumps simultaneously. Doing so can cause damage to both systems and lead to increased energy costs. However, some types of heating and cooling systems, such as those with an auto mode feature, can automatically adjust the temperature setting to maintain a comfortable temperature in your home.

What is the Symbol for Heat Mode on the AC?

The symbol for heat mode on your AC can vary depending on the brand and model. However, a common symbol is a sun or a thermometer. For more precise information, refer to your user manual or contact the service providers.

How to Set AC Temperature for Heating?

When setting your AC temperature for heating, a rule of thumb is to aim for a comfortable temperature that also allows you to be energy efficient. This is often between 68-72°F (20-22°C). However, you might adjust this depending on personal preference and the specific heating season.

How to Turn on Heat in House?

Turning on the heat in your house depends on the type of heating system you have. For central heating or combination heating systems, it generally involves switching your digital thermostat to heating mode.

For furnace heat, ensure the pilot light is on. Always consult the instruction manual or call a professional service to help you if you don’t know how to light your furnace yourself.

Maintenance Steps to Take When Switching from Heating to Air Conditioning

When making the switch from heating to air conditioning, it’s important to follow these maintenance steps:

  • Check and replace your air filter
  • Clean and inspect the blower housing secondary
  • Ensure your heat exchanger is in good condition
  • Check the outdoor air conditioning unit for any debris
  • Make sure your thermostat is functioning properly

How do Air conditioning and Heating Systems Differ?

Air conditioning and heating systems operate on similar principles but in opposite directions of heat transfer. AC units remove heat and humidity from the interior, expelling it outside.

On the other hand, heating systems like heat pumps, fuel oil and oil heat systems, or furnace heat systems add heat to the interior from an external source.

Does Air Conditioning Use the Same Parts as Heating?

Some parts of an air conditioning system, such as the blower fan and the thermostat, are also used in heating.

However, each system has components unique to its function. For instance, an AC has a cooling coil, while a furnace includes a heat exchanger and burner.

When Should You Switch Between Heat and Air Conditioning?

The perfect time to switch between heating and air conditioning depends on external temperatures and personal comfort levels. However, a general rule is to switch to heating when temperatures consistently fall below 60°F (16°C), and to air conditioning when temperatures consistently rise above 75°F (24°C).

Final Thoughts

As we move through the seasons, transitioning between heating and cooling is a necessary task for maintaining a comfortable temperature in our homes. Understanding how to smoothly make this switch can save you unnecessary stress on your systems and keep your energy bills in check.

Regular maintenance and being attentive to the age of heating boilers and AC units will help you achieve peak efficiency. By following the guide above, you’ll be well-prepared to make the switch between your air conditioner and hea
