Another fairly evident element to air conditioning repair that is a safety concern is specific to the window and wall mounted devices Day & Night Air . These devices can be exceptionally heavy for their little size and generally are awkward and challenging to physically deal with for one person. If during the repair you have to remove the air conditioner from its mounting, be sure to have at least one other individual to assist with the job. This can be far more challenging with heavy window mount devices that will require someone on the inside as well as someone on the exterior of your house to successfully relocate the device without harming the window frame or resulting in some type of physical injury.
Sometimes where the conventional or forced air cooling systems are used, the installation might have been done incorrectly and the vent lines from the air conditioner might have been incorrectly hooked to the sewage lines or the plumbing vents. In these circumstances, the system can build up dangerous levels of bacteria in the moist, wet conditions created in the lines plus sewer line gases can also back up through the air conditioner creating severe health concerns. If any nasty smell or odor is noticed in the air conditioning system or in the air when it is on, do not attempt the air conditioning repair yourself, rather, call in an expert that can safely remedy the problem.
Newer air conditioning devices utilize various other coolants that are safer than Freon, however even Freon itself is not harmful in small amounts unless there is an open flame present. If you believe that the air conditioner is leaking coolant or if you smell any “odd” smells in the room or air after finishing some type of air conditioning repair the best option is to turn the unit off and immediately speak to a trained and licensed technician. Since Freon is odorless, it is most likely not the problem, however, there could be some other problem that is causing the noticeable odor. Make certain all heaters, stoves or other type of flame is totally out in your house or area till the unit can be checked and fixed.
