Who cares if the flooring inside the closet doesn't match. I wish you luck in your effort to stay cool. Don't hesitate to contact me if I can help. Residential air conditioners, both central and window units, are like shoes.
They come in various, different sizes. Buy the wrong shoe and you will be uncomfortable. It is no different with air conditioning. So you really want your house cold. What are you going to do? Buy a monster 5-ton central unit? That could be a mistake. If you put in a unit that is too powerful produces too much cooling , it will short cycle. It will turn on, blast out vast quantities of cool air, and then shut off.
The result will be improper dehumidification. You will be cool and clammy. The air conditioner needs to run for a sufficient time to squeeze out the humidity that has seeped into your house. You achieve the highest comfort when the air conditioner removes as much humidity as possible from your interior air.
To properly size an air conditioner, one has to perform a heat gain calculation. In other words, you must determine how fast heat is getting into your house and what things inside the house are contributing to heat gain.
To perform the calculation, you need to know how much insulation is in your exterior walls, how much is in your attic, the size and type of glazing for each window, the type of construction of each window, extra special lights or cooking appliances that generate heat, compass direction that each wall of your house faces, etc.
In other words, you have to do some work to get the equipment sized right. Tables and charts have been around for years that convert these measurements into BTUs. Once you know how many BTUs your house is gaining, you can purchase the correct sized air conditioner. When purchasing a unit, ask for these calculations! Don't just buy the same size unit you now have.
Maybe it was not sized right. Maybe you have upgraded your windows or insulation. Maybe you added a small or mid-sized room addition or remodeled an attic space. If you have an existing house that needs a new central AC unit, be careful! For you to achieve the published efficiency and performance that is sold to you by the salesperson, the interior coil housed in the furnace must be compatible and matched for size!
If it is not, the outdoor unit will struggle to keep your house cool. It is a question you must ask the installer. Remember, the inside coil could have been wrong from the beginning! The original furnace contractor could have downsized one size to save money. These forced air systems also need vents for return air. Back then the cold air returns were in the floor.
So should you install cold air returns high or low? You can do both. In most homes the builders will use the wall cavity as a cold air return. That means the space between two wall studs.
If you have this type of air return system in your home then you can have a vent at the ceiling and at the floor. In the picture you can see the cold air return close to the ceiling. I needed to do some drywall repair so while I had the wall open I installed a plaster ring for the cold air return vent.
You can see how the cavity in the wall is used for the return air. I outlined the plaster wring in black so you can see it. First go to your local home improvement warehouse and find a vent that you can open and close. Purchase two of them. Try to find one that is the same size or bigger than the one you already have so you wont have to patch drywall.
Install one in your existing location. Then in the same line as your existing vent cut a hole in the drywall just above the base boards and install the other vent. In the winter close the top vent and open the bottom and the cold air close to the floor will be drawn in. If this is the case, you should mark it. From the bottom mark, you should make a top mark as well. Make a mark in both of these locations. The stud should be cut on the bottom and top lines.
This will help ensure that the studs remain sturdy. You can cut the lumber using a circular saw. You should have a piece for the top and a piece for the bottom. You can put the lumber in place and secure them using nails. Make sure that everything is perfectly secured before moving on. Use a pencil to place marks on the bottom and top of the headers. The duct work should be placed through the opening you just created. Remember to add some insulation to the equation.
This will provide you with the best results and help keep the air inside. The insulation can be sealed by utilizing metal foil tape. You should measure the height from the bottom and top headers.
This will be your jack studs. These studs should be placed on both sides of the duct work. A small gap should be left between the studs and the insulation.
