If you have some carpentry skills it generally isn't that hard to resize your opening, but it's a chore. You can probably find something modern and efficient that will blow freezing cold air and fit easily into the existing opening with minimal alteration. You're definitely going to get spendy if you want to retrofit an old house with central A/C. You could blow through $10,000 pretty easily depending on the house.

Instead they have a wall unit (looks the same as window unit, but hole in the wall). best way to clean outside ac unitThe unit looks old but functions. air conditioning units for hire londonI have noticed in wall units cost significantly more than windows units. cheap outside ac unitsI have no idea why, they look the same to me.

At any rate I have decided that when the unit dies out I am going to fill the hole, possibly with a window and install a mini-split/heatpump system in the room. It looks like it'll be in the neighborhood of $2000, but they are much quieter and a whole lot more efficient. Since I plan in spending a significant amount of time in this room I have little desire to hear the rrruuueerrrr rrruuueeerrr sound of an in wall air conditioner. So yourself a favor, look into the mini-split systems. Lots of videos on youtube showing them. Lots of info to be found online. Mind you, we are not living in this house yet, but will be next month. I already brought the mini-split system idea to DW. At that price she laughed at me. However, I have a feeling once she lives in that room with the loud AC unit, she'll be more than happy to go mini-split when its time to replace it.Ask an assistant to help you remove a wall-mounted air conditioner on the second floor. Smaller homes and certain rooms within larger homes often have a wall-mounted air-conditioning unit that fits into the wall.

The controls are on the inside of the building and the exhaust vent is on the outside. If the unit is not delivering the desired temperature of air as it should, the unit should be removed and tested at an air-conditioning service center. In most cases, removing a wall-mounted air-conditioning unit takes a relatively short time. Unplug the power cord from the unit at the electrical outlet inside the room. If the unit is hard-wired, switch off the breaker for that electrical circuit at the breaker panel for the house.

Cut the bead of caulking where the wood trim meets the face of the inside wall, using a utility knife. Remove any trim or casing from around the outer edges of the unit by prying the pieces loose with a wood chisel. If necessary, use a light hammer to drive the tip of the chisel beneath the trim. Skip this step if wood trim or casing is not installed..

Look for small screws that secure the cover of the unit to the main body, and remove these with the appropriate screwdriver, then pull off the cover by hand. Where screws are not used, gently pry the cover loose with a screwdriver, and pull it off of the unit. Go the outside wall of the house where the unit is installed. If necessary, place a stepladder for access to the outside portion of the unit. Remove the screws from the bottom, top and sides of the chassis, or outside cover. Push on the vents at the rear of the unit by hand to unseat it from the chassis. Go back inside the room. Grip the sides of the unit and pull it toward you to remove it from the chassis in the wall. If the unit will be replaced, loosen and remove any screws that secure the chassis to the framing in the wall, and pull out the chassis. How do you change the filter on an in-wall air conditioner?

Some air conditioners may have an air filter in the furnace, which may be located behind a filter cap or a plastic or metal housing. After removing the old filter, it is necessary to find an appropriate replacement. There are fiberglass, pleated and media filters. Fiberglass filters look similar to the screen in a window, but with a bigger frame. Pleated filters are roughly 1 inch wide and rectangular. Media filters are also rectangular and usually around 4 inches wide.

People who are not sure what kind of filter they have can bring it to a hardware or home goods store to compare it to new filters. This can be helpful to determine accurate sizing as well.
