These sleeves will usually accompany NEW products , either as a package or an add on equipment purchase.Contact a Licenesed PROFFESSIONAL at once ! Some HVAC contractors do sleeve installs, some sub them out to a General Contractor, because it involves cutting into the wall, maybe relocating electrical or plumbing if you are confined to a bad location, then installing the sleeve and properly tying it into the interior wall and siding, insulating the gaps, and properly waterproofing the interface - not the sort of things HVAC contractors usually do or do well.

And if a large unit, requires a carpenter to put in a header over any studs that are cut out.The actual install of the unit can actually be legally done by anyone, at least under federal law - the part that specifically requires the license is the charging with gas and the approval to start up. OF course, using anyone but an HVAC contractor to install one makes little sense, plus of course to keep the warranty you have to go that way except with a self-contained plug and go unit like a window air conditioner.

How long to replace a AC evaporator coil? Easy access in garage. Ac unit right behind unit out side the wall. As suggested I replaced a new sears AC unit for freon leak but still leaks. How often should a central AC unit be serviced if there is no problem?Sandwiched between the coils are a compressor, two fans, a motor, and thermostat controls.

Both of the major components of a room air conditioner are contained in one housing. The condenser coil faces outside, and the evaporator faces inside. The coils, the compressor, and the motor of a room air conditioner are sealed components, so any repairs to them should be left to a professional service person. Otherwise, let an air conditioning technician do it.Now that you're ready to work on your air conditioner, try to determine exactly what needs to be done. Look for your problem, and solution, on the chart on the next page.Although a portable air conditioning unit is designed to fit in a window opening, its downside is that it prevents opening the window in mild conditions for natural cooling. By building a unit into a wall, you can free up the window for operation and have a permanent installation. This works particularly well for cooling a small addition or part of the house that isn’t cooled naturally. A key requirement is to place it near a 115-volt electrical outlet, or have one added near the location on the wall.

A carpenter will build a 10,000 BTU energy-efficient air conditioner into a wall for $730, which includes the labor, framing material and the unit. central ac india priceIf you have carpentry experience, you can do the job for $540, the cost of the unit and framing material, and save 26 percent. used heating and air conditioning units for saleYou’ll have to cut away enough of the interior wallboard to frame in an opening. how much are air conditioning unitThen you cut the siding to match the framing and position the unit in the opening and secure it.

Gene and Katie Hamilton are veteran do-it-yourselfers whose column, “Do It Yourself Or Not,” has been in newspaper syndication for 20 years. They've been in the home improvement trenches long enough to know when to hire a contractor and when to do a project yourself and share their sage advice with real life experience and dollar and cents figures. The award-winning authors have penned 20 home improvement books. Their latest best-seller, “Fix It and Flip It,” is a handbook for investors who want to buy, fix and sell houses.

The Hamiltons are best known for their quirky, no-nonsense philosophy of home improvement and demystifying a home repair so it's not intimidating. Their offbeat humor can be found in a series of “Dummies” titles including “Painting and Wallpapering for Dummies,” “Plumbing for Dummies,” “Carpentry for Dummies” and “Home Improvement For Dummies.” , the first home improvement site on the Web.

Basic Rule No. 1: Hot air rises, cold air falls.Ducts should be installed to take maximum advantage of natural air movement. For instance, for air conditioning to work properly, air returns, the large ducts that carry air back to the central unit, need to be installed high up on the wall of each upper floor, to capture warmer air and return it for cooling. Efficient heating means installing a return at a low point on the first floor, to capture cooled air and return it for heating.Registers that deliver warm air should be in the floor or low on the wall; registers to deliver cool air should be installed high up on the wall. (The best systems may require a mix.)Basic Rule No. 2:Ducts should be installed so they run as straight as possible from the basement to each register. That's because the more turns you make, the slower the air will move and the less air will be delivered to the register.Basic Rule No. 3:Every register should be fed directly from the central unit (or basement trunk line) by its own duct.

If you stacked registers on a single duct on second and third floors, for instance, all the heat would go to the second floor.Basic Rule No. 4:Map out your duct path to upper floors before you start cutting any holes. Ducts should be able to run between studs in the wall and then turn into a joist bay (the space between two joists). Make sure the studs and bays line up well enough to leave a clear path.Basic Rule No. 5:When you make a turn, use a fitting designed for the purpose. That will keep the air moving efficiently. (An old-fashioned shortcut was to make square turns, but they cause eddies that reduce air movement.)Basic Rule No. 6:Plan heating ducts to emerge at external walls -- those are the coldest walls. Registers should be placed in the middle of the external wall (in the floor or low on the wall); if there are two external walls, both need registers in the middle. (If the room is tiny, one duct may work, even if there are two external walls.)Basic Rule No. 7:Ducts that run through unheated spaces should be insulated.

An uninsulated duct will lose a lot of its heat on the way to the register. (This rule is especially important if you're putting an addition over an unheated crawl space.)Even if you're not installing the system yourself, knowing the rules will make you a more informed heating and air-conditioning systems consumer.In our case, we hired an installer to put in the furnace, the air-conditioning equipment, basement trunk lines, exhaust flue through the roof and the largest air return, which goes to the very top of the house, a cathedral ceiling on the third floor.The rest of the ductwork we're doing ourselves -- partly to save money, but partly because we are so fussy about where it goes.We always add a couple of rules to the basics. For instance, because it's an old house and we're retrofitting with the first real heating and air conditioning the structure has ever had, we don't want it to show. So all the ducts will be concealed in the walls and ceilings. There'll be no chases (drywall boxes), except for the largest cold-air return and the exhaust flue, which run on either side of an existing fireplace flue.

We were able to use one of these chases for some plumbing pipes as well, and to conceal it behind a closet on the second floor.Our other extra rule is that air conditioning has to be just as effective on upper floors as it is on the first floor. That means running high air returns for every major room on the second and third floors.Fortunately, we discovered something called "button-lock oval pipe," which is easy to work with and fits neatly into the space between 2-by-4 studs. It comes in 5-inch, 6-inch and 7-inch widths, so it delivers a lot of air. There are dozens of fittings to connect it around corners, to registers, and to round pipe (used for floor registers).Where it's necessary to join two lengths of oval pipe, we've been using two half-inch sheet-metal screws and wrapping the joint with aluminized duct tape that is so strong it would hold the pieces together by itself.Unfortunately, we discovered all this neat stuff at a wholesale supply house, and not in our local home-supply supermarkets, which means it's hard for do-it-yourselfers to buy.
