When renovating an old house, one of the most common and most expensive things to repair or replace is the air conditioning system. Some homes do not have any at all and may need a new installation. This is a big undertaking that can also be financially overwhelming. Depending on other repairs, comfortable room temperature may need to take a back seat to roofing and structural renovations. Portable air conditioning units are more affordable than repairing, replacing or installing a central air unit.

Use

One alternative is to use portable air conditioners. These units cool an area well and can be moved from room to room as needed. The square footage for cooling capabilities varies from model to model, but they can generally handle areas up to 450 square feet. The units do not require any type of central control and take up little space. Most models are electrical with a standard plug. For old houses that have somewhat modern electricity, an adapter or straight plug into the wall will be sufficient.

Considerations

Portable types are equipped with a catch can for moisture that prevents the unit from having to be attached to a window. Some types have a hose that can be run out through a window, but the window is functional while this hose is in place. While window a/c units are effective in cooling a room, they are too heavy to move with any regularity and must be attached to a window. Unlike with the portable models, the windows cannot be opened during cooler summer days without losing the window unit. In this case, opening up windows in an old house to get rid of the musty smells during renovation is not an option either.

Features

When using portable a/c units, they are often on wheels and can be rolled from room to room at will. Some models come with a kit that allows them to be installed in a window as well. When the window needs to be used for other purposes, it can be removed without great effort. They average about 40 to 60 pounds in weight and can be moved by one or two people. Many models contain self-evaporative technology. As moisture builds up in the unit it evaporates with help from an exhaust fan. Larger, more expensive types do more than cool down a room. There are some that can be used as heaters and dehumidifiers and fans.

Conclusion

When remodeling an older home, portable air conditioning units can be used to make the house more comfortable for both the people working on it and those living in it. Especially during the summertime, rooms without comfortable temperatures can make renovating a classic old home more difficult and not quite as inviting.
