Hospital operating theatres, in which air is filtered to high levels to reduce infection risk and the humidity controlled to limit patient dehydration. Although temperatures are often in the comfort range, some specialist procedures, such as open heart surgery, require low temperatures (about 18 °C, 64 °F) and others, such as neonatal, relatively high temperatures (about 28 °C, 82 °F).
In very dry climates, evaporative coolers, sometimes referred to as swamp coolers or desert coolers, are popular for improving coolness during hot weather. An evaporative cooler is a device that draws outside air through a wet pad, such as a large sponge soaked with water. The sensible heat of the incoming air, as measured by a dry bulb thermometer, is reduced. The temperature of the incoming air is reduced, but it is also more humid, so the total heat (sensible heat plus latent heat) is unchanged. Some of the sensible heat of the entering air is converted to latent heat by the evaporation of water in the wet cooler pads. If the entering air is dry enough, the results can be quite substantial.
HVAC pros are busy, especially in the summer. Just because you need an AC repair right now, that does not mean an HVAC pro will be available. Additionally, if they are free, your cost to repair the AC unit just went up. Emergency situations call for changes in schedules, surprise road trips and many other sudden situations. As such, air conditioning contractors tend to charge more.
One of the easiest maintenance tasks consumers can do themselves is maintaining the filters. Air filters should be inspected and cleaned once a month. This allows for regular monitoring to eventually determine when the filter needs to be replaced. Most filters can be changed every three months if no other problems exist. Maintaining clean and regularly changed filters will not only produce better air quality, but appliances will function more efficiently, which can save on heating and cooling costs.
If the unit isn't turning on, check on it outside to make sure the condenser is still running. It should be fully plugged in and the thermostat should be set. Lower the thermostat by a few more degrees than your typical setting. You should hear it power on after doing so. If that doesn't take care of the problem, check your fuse box. You could have a blown fuse or a tripped circuit that's causing the air conditioner to not turn on.
