Through the Wall Air ConditionersThrough the wall air conditioners offer an effective, convenient and energy efficient way to cool your home. They're a lot like window units, but they're installed through a hole in an exterior wall rather than a window, so they're a good choice for rooms without suitable windows. Through the wall air conditioners are also often more energy efficient than window units, since they create an airtight seal.In order to install a through the wall air conditioner, you'll need to make sure you have an exterior wall with an area that's free of pipes and electrical structures. The unit is generally installed in a wall sleeve, which may be a through-the-wall sleeve or a slide-out chassis.Before choosing an air conditioner, determine how much cooling power you'll need. A 150 to 300 square foot space will require about 5,000 to 6,000 BTUs, a 400 to 600 square foot space will require 7.000 to 8,000 BTUs, a 600 to 950 square foot space will require 9,500 to 12,500 BTUs, and a 950 to 1200 square foot space will require 13,000 to 21,000 BTUs.

Also, consider what special features you may want, such as a remote control or a timer.At Walmart, you'll find Every Day Low Prices on air conditioners and other heating, cooling and air quality supplies. Heating & Cooling 101 The following products are called 'Unitary' air conditioners: • All Packaged Terminal Air Conditions (PTACs), • Vertical Terminal Air Conditioners (VTACs), • Window Room Air Conditioners (WRACs), • 26" Through the Wall Air Conditioners (TTWs) Unitary systems are single units that provide both heating and cooling operations from one product. This is different from the air conditioning systems used in most North American homes which use split systems. This name is derived from the fact that two components are required to complete the system; an indoor coil (inside the home) and an external condenser (outside the home).Using electricity as its power source, the unitary system compressor pumps refrigerant through the system. The refrigerant attracts heat and moisture from indoors and then transfers it outdoors.

Heat and moisture inside are removed when warm air passes over the cool indoor coil. The heat and humidity in the air are removed by the coil, thereby "cooling" the air indoors. When the unitary system operates in the heating mode, the unit operates in reverse. The refrigerant is used to create a heated indoor coil. As air passes over the heated coil the heat is transferred to the air inside the room creating warm air. Indoor comfort all year – Unitary systems can rapidly remove heat and moisture from indoor air. You simply set the units thermostat to the temperature that you desire and the unit automatically cools to that level. You can manually select fan speed or use the automatic fan speed setting. When you need the room to be heated you use the same basic settings. Just set the thermostat to the temperature you want and select the heating function.Simple Installation – Unitary systems are easy to install because they come in standard sizes and shapes. Regardless of the heating and cooling load requirements, the unit is the same size.

Since both the heating and cooling systems exist inside a single unit, installation is easier than the installation of a split system.Independent Operation – Unlike split -system heating and cooling systems which condition whole buildings through the use of ductwork, unitary systems cool and heat only the rooms or spaces where they are installed. coleman ac unit partsThis means you cool or heat only what you want with individual temperature control. floor ac unit reviewsWith multiple unitary systems installed, you can easily control indoor temperature on a room to room basis.​ cleaning a window ac unitPTAC Interior and Exterior Let Energy Rebate Programs Work For You Busting Myths About Electric Heat Pumps Heat Pumps vs. Baseboard Heat: Two Very Different Ductless Options

Turn off the electricity to the circuit. 2. Hold mounting bracket to the wall, level it, then mark the screw hole locations and where to bore a hole for the refrigeration lines, condensate discharge line and electrical cable. 3. From inside, bore hole into the block wall with rotary hammer and 3-inch-diameter masonry coring bit. Once the bit's pilot penetrates the wall, finish boring the hole from the outside.

4. Screw the mounting bracket to the wall, making sure it's level. 5. Install the air-conditioning unit to the wall-mounted bracket. Pass the refrigeration lines and condensate discharge line through the hole in the wall. 6. Attach a vertical chase directly below the hole in the exterior wall; the chase will house the refrigeration lines, condensate discharge line and electrical cable. 7. Extend the condensate discharge line down to within a few inches of the ground by attaching a length of PVC pipe. Secure the discharge line to the pipe with duct tape. Fasten the lower portion of the pipe to the chase by screwing on a metal C-clamp. 8. Carefully bend the copper refrigeration lines down into the chase. Use two adjustable wrenches to remove the compression fittings from the ends of the copper lines. 9. Slide a brass nut onto a new length of copper tubing, then use flaring tool to flare the end of the copper tubing. 10. Hold the tubing's flared end against the end of the refrigeration line coming from the air conditioner.

Hand-tighten the nut to hold the copper tubing to the refrigeration line. Repeat to attach the remaining refrigerant line. 11. Set the outdoor condensing unit onto a level pad adjacent to the chase. 12. Use two adjustable wrenches to tighten the compression fittings on the refrigerant lines. Then wrap pipe insulation around each line. 13. Run weather-tight conduit from an outdoor electrical box to the condenser unit. Feed electrical wires through the conduit. 14. Run a length of nonmetallic electrical cable from the condenser unit through the hole in the wall to the indoor air conditioning unit. 15. Snap the cover onto the chase to conceal and protect the lines and cable. 16. Make all electrical connections at condenser and at air conditioner, then pressure test the system with nitrogen to 300 pounds per square inch. 17. Vacuum out the nitrogen, then open valves to release refrigerant into the system. 18. Turn on the electricity and test the air conditioner.
