Can You Use Air Conditioning While Exterior Painting? Essential Knowledge to Keep in Mind – Explained by Kakeru Koumuten Co., Ltd.!

When performing exterior wall painting, you generally cannot open the windows.

Therefore,

“How can I adjust the indoor temperature?”

“Can I use the air conditioner as usual?”

Many people may have these questions.

In this article, we will explain in detail the availability of air conditioner usage during exterior wall painting.

 

Can the air conditioner always be used?

During exterior wall painting, the air conditioner cannot always be used.

In some cases, it may temporarily become unavailable.

Let’s take a closer look at when it can be used and when it cannot.

 

Cases where it can be used without issues

If the outdoor unit is not removed during the work and no protective measures are taken, it can be used without any problems.

Moreover, even if protective measures are taken for the outdoor unit, it is rare for it to be covered throughout the entire construction period, and it is often removed after the painting around the outdoor unit is completed.

In recent years, more contractors have been installing covers to allow the use of air conditioners, so it is advisable to check in advance.

If there is a possibility that the air conditioner may not be usable, please also confirm:

・How long will it be unavailable?
・Is there a way to make it usable?

 

Cases where the air conditioner cannot be used

If the outdoor unit is attached to the wall, it may be necessary to temporarily remove the outdoor unit to paint that area.

In this case, you will not be able to use the air conditioner, so caution is required.

However, whether or not to remove the outdoor unit is up to the client’s decision, so if you express a desire not to have it removed, it can be used without any issues.

 

Additionally, it often cannot be used while high-pressure washing is being performed.

This is because high-pressure washing typically splashes water vigorously, making it common to protect surrounding equipment.

However, this process does not take a long time, so it is rare for it to be unusable for several weeks.

 

Are there any countermeasures if the air conditioner cannot be used?

During spring or autumn, it is possible to live without using the air conditioner, but especially in midsummer, not having an air conditioner can lead to health issues.

If you are considering painting in the summer, please try the countermeasures introduced in the next section.

 

Consulting as a last resort

If you want to use the air conditioner during exterior wall painting, it is recommended to consult with the contractor.

If a contractor prioritizes the customer, they will find ways to make things work.

For example,

・Remove protective coverings when not painting
・Install a protective cover that allows the air conditioner to be used

and so on.

If you don’t consult in advance, there may be times when you cannot use the air conditioner throughout the construction period, so be sure to discuss it beforehand.

 

What you need to be careful about here is that you should consult before signing the contract.

Some people may consult after the construction has started, saying,

“I want to use the air conditioner after all,”

but depending on the contractor, there may be cases where they cannot accommodate this.

Therefore, during the planning stage, discuss whether the air conditioner can be used, and if they say it cannot, let them know you would like them to take as many measures as possible.

 

Use another air conditioner inside

If you have multiple air conditioners, using one that is not related to the work is one option.

This way, it won’t interfere with the exterior painting work, and you can live comfortably at a suitable temperature.

That said, there may be times when there is only one air conditioner in the house.

In such cases, it is advisable to consider other measures, such as going out only during working hours.

 

Could using the air conditioner cause problems?

Regarding the use of air conditioners during exterior painting,

many people think, “I can just consult if I need it,”

but there are cases where it can lead to problems.

So, let’s take a closer look at what kinds of problems are likely to occur.

 

Thought I could use the air conditioner, but I couldn’t

If there has been no confirmation about the air conditioner before the construction, there may be a discrepancy in understanding between the contractor and the client.

In such cases, it can lead to situations where you think,

“I thought I could use it, but I couldn’t!”

To avoid such troubles, it is advisable to confirm with the contractor in advance, and if it turns out you really can’t use it, to decide to request another contractor.

Some contractors may casually say,

“You generally can’t use the air conditioner during exterior painting,”

but there are also contractors who will make various arrangements to allow you to use it, so it’s a good idea to consult multiple contractors.

 

The protective covering was insufficient, and paint got on the outdoor unit

If you do not protect the outdoor unit to use the air conditioner, paint may get on it.

If left unattended, the paint can dry and become difficult to remove, so it is recommended to inform the contractor as soon as you notice it.

During the construction period, most contractors will remove unnecessary paint from the outdoor unit.

However, once the construction is completed, they may no longer accommodate this, so it is important to inform them early.

 

Couldn’t stand the heat and turned on the air conditioner, causing paint smell to come in

Most air conditioners are designed not to draw in outside air, so the likelihood of paint smell entering the room is low.

However, there are types of air conditioners that draw in outside air into the home, so we recommend checking your home’s air conditioner carefully.

Additionally, even air conditioners that do not draw in outside air can take in outside air when set to “ventilation,” so it’s best to avoid using such modes.

In general households, water-based paints are often used instead of oil-based ones, so the smell is usually not too strong, but it is not completely odorless, so please take proper measures against odors.

 

How to Have Exterior Painting Done Without Stress?

To have exterior painting done without stress during the summer, the ability to use air conditioning is indeed an important factor.

If air conditioning cannot be used at all, it can not only make the environment uncomfortable but also pose a risk to your health, so you should look for a contractor who can make arrangements to allow air conditioning to be used.

 

Another option is to request the work during a time when you can live comfortably without using air conditioning.

This way, you can save the trouble of discussing or negotiating the use of air conditioning with the contractor.

 

Conclusion

There may be times when air conditioning can be used during exterior painting work, and there may also be times when it cannot be used depending on the work being done.

Depending on the season, it is possible to live comfortably without air conditioning, but during the summer, not having air conditioning can lead to discomfort.

For this reason, especially when requesting work during the peak summer months when temperatures exceed 30 degrees, it is advisable to discuss the use of air conditioning with the contractor in advance.
