Edit ArticleHow to Maintain an Air Conditioner The amount of maintenance a homeowner can perform on an air conditioner is rather limited, but some simple, easy to perform steps can breathe new life into an older, poorly performing units or those that produce foul odors. Read on for more. Unplug the air conditioner. Remove the filter and bezel or cover of the unit if needed. Spray the front coil of the air conditioner with a cleaning agent designed for this use. Replace cover and filter and restore power after about 10 - 15 minutes. Run the air conditioner. Shut the unit off and disconnect power. Inspect the outdoor coils. Clean the outdoor coils if desired. Rinse foaming cleanser away with garden hose. Reconnect power and test. Know when it's time to get a new one. Air conditioners that fail to get more than just "cool" may respond favorably to an indoor and outdoor coil cleaning. If it does not - it could indicate a failed compressor or lost refrigerant charge.

This problem is nearly always more expensive to repair than replace - except for the cases of very large value BTU units (12,000 - 15,000 BTU and larger) and Central Air Conditioning Systems. Apply these same steps to Central Air Conditioning systems, too. The "air handler" in an attic space or basement contains the "indoor coil" and the compressor unit outside contains the "outdoor coil". Always follow directions on cleanser can and use only as directed. A dirty filter or dirty indoor coil can result in "ice ups" of the indoor coil. Ice ups will block the flow of cool air into the space and contributes to coil and compressor failure. Dirt is an air conditioner's enemy. Dirt acts as a thermal insulator and robs efficiency - ultimately driving up the cost of operation. A dirty outdoor coil can impede the ability of the coil to give up the heat collected inside. Shrubs, fencing, etc. can reduce air circulation around the outdoor coils, and have similar effect as a dirty coil.

Allowing either condition to exist for a long period can cause compressor failure.

Manuals, Information & Guides Shop For Your Lennox® System Costco Contractor License/Registration ListSticking outside in all their boxy metallic ugliness, dripping onto passers-by, and blocking light and views indoors, window mounted air conditioners are as ubiquitous a feature of NYC apartment life as fire escapes and water towers.  

(For more info, check out BrickUnderground's guide to all things window a/c).PTACs are usually installed when a building is constructed and hooked up to a building’s hot-water system.  Hot water produced by the boiler flows into the PTAC, and circulates the resulting heat into the apartment.  The PTAC has a separate chamber containing coolant that produces cool air.  They are vented to the outside through a cutout below the window typically covered with a metal grill, similar to a through-wall a/c, says Gary Cottam of Cottam Heating & Air Conditioning. 2. Choosing the right through-wall unitFriedrich, LG, GE, Amana, and Frigidaire are the most popular brands.  There are standard calculations  to determine the number of BTUs you need--room size, ceiling height, amount of sunlight, number of occupants, and proximity to the kitchen.And don’t forget to jot down the voltage and amperage of the electrical plug, along with the capacity of the outlet the a/c will use.  If you’re buying a unit that requires more electrical power than your existing outlet can handle, you’re going to need an electrician to upgrade your wiring. 

And that will require lots of permits along with permission from your landlord, or co-op or condo board.3. Installing a through-wall a/c where none has gone beforeAlthough cutting an opening through the masonry of an exterior wall is physically a relatively simple undertaking that costs around $2,000, like most things connected with New York City real estate you’ll have to get the requisite building and construction permits, permission from your landlord, co-op, or condo board, and maybe even an architect,  says Ranjit Singh, president of Cool Air Inc.Arline Kob, a principal at Key Real Estate Associates, which manages co-ops in New York, says that she’s “never known a co-op board to allow the installation of a through-the-wall unit where none exists.”  The board would be concerned about façade uniformity and breaking the seal of the building’s exterior. If your board is through-wall-friendly, you will be expected to install an exterior grille that matches existing ones and lines up to them, says property manager Michael Wolfe of Midboro Management.  

The grilles will also need to be flush with the building's facade and the building's architect or engineer will need to review the proposed installation.In addition, says Kob, "the resident and future buyers, not the co-op, would be responsible for maintaining the newly installed sleeve and the wall into which it was cut.  That includes damage to surrounding apartments that may result.”If you live in a landmarked building or district you’ll have to get the go ahead from the Landmarks Preservation Commission too.  Good luck with that, especially if the altered wall will be visible from the street.  “Landmarks would never allow it,” says Kob.Because a PTAC is hooked up to the building’s water, the units need to be rigorously maintained to get rid of clogs that can cause leaks. These can go unnoticed for long periods of time, causing floors and walls to buckle and often damaging apartments below the one in which it’s housed. Damage from PTAC units is, in fact, among the most common apartment insurance claims in New York City, says Jeff Schneider of Gotham Brokerage, with an average claim size of $5,000.In addition, PTAC units are prone to the musty, mildew-y odor known as 'dirty sock syndrome', which is generally thought to be caused by bacteria and mold accumulating on heat pumps.
