Factors That Affect the Ideal Temperature for a Vacant House

What Temperature to Leave a Vacant House

When you think of what condition to leave a vacant house in, you also think about the heat settings of the home. Having the right cooling and heat settings can make all the difference in avoiding hazardous damage and saving energy costs

As we know not all accommodations are built the same. So, there is no one-size-fits-all solution. There are several factors that you need to address before you can set a  proper environment and go on that vacation without worrying. 

It’s important to consider the home location, insulation level, plumbing, its condition and kind of heating and cooling system, duration of unoccupied period, and desired level of comfort for the homeowner’s return. 


One of the most important elements when calculating the ideal condition for your home is the location. The climate of the area that you live in, determines the ideal heat for your residence. In locations like Canada and the North of the USA, heating levels are often low. The climate of the house needs to be maintained above freezing point. 

However, if you live in a warmer climate, the heating system can be set to a lower degree. This will also help in saving air conditioning costs. Another thing to consider is what season you will be leaving your home vacant. If it is vacant during summer the atmosphere will be different. If you leave a higher degree you can prevent your living space from getting too hot and humid, which can lead to mold growth. 


The insulation of the home is an important wave to keep in mind. The type of insulation you have installed can affect the conditions of your lodging. A very well-insulated house can maintain warmth for a longer time. 

While on the other hand if the house is not well insulated, then there is a possibility that your pipes might freeze if, you don’t set the temperature higher. 


The plumbing system of your residence must be taken into account when choosing the right cooling or heating system for a vacant home. As we know if the level of the warmness in the house drops, the water in the pipes will freeze. Which causes the pipes to expand and burst. This can further cause severe damage to the property. 

To avoid this mishap the owners should set the thermostat in such a way that it is high enough to prevent the pipes from freezing and low enough to save energy costs. The ideal range is between 50 to 60 degrees Fahrenheit.

To stop this from happening, it is important to set the thermostat to a degree that is high enough to keep the pipes from freezing, yet low enough to save energy. By doing this, homeowners can protect their homes from potential damage while also being mindful of their energy consumption.

Seal all the drafts, drafts are little spaces or cracks that let the cold or warm air out of the house. The drafts can let in the cold air in winter and hot air flow in summer. If you seal all the drafts of your house you will feel a notable change. Drafts are usually found in doors, windows, air vents, and other areas stripped by the weather. 

Insulation of your rooms is the most important part. Good insulation will keep your living space  warm in winter and cold in summer. Insulation creates a barrier between your home and the outdoors. Try insulating your attic, floors, and walls and save money on energy consumption. 

Ceiling fans are a great way to keep your home airy throughout the summer. Ceiling fans help spread the air flow throughout the living and keep you from feeling warm. A little tip for winters is that, if you set your fan to rotate clockwise it will push the warm air downwards. 

You can also keep your home warm in winter by closing the curtains and blinds. Closing the blinds in summer will prevent direct sun heat from getting into your home and making it warm.
