Airconditioning Maintenance
Unit will not start
Actually, the most common reason for this complaint is usually that the unit is not properly switched on at the thermostat. Make sure that the heat/cool selector switch is turned to "cool" and make sure the thermostat is turned well below room temperature so that there is no doubt that it should be calling for the cooling to come on. If the unit still will not come on, check all breakers and fuses that feed power to the unit. Make sure to observe safety-first guidelines when working with fuses and breakers. If you are sure that the power is on to the system (there is usually more than one circuit) you probably will need to call for professional help.
Unit doesn't cool well
The most common reason for this complaint is an air conditioner has lost part of its refrigerant charge because of a leak, but there is a few other things that can cause the same symptom. Make sure that you have done your normal air conditioning maintenance. If you still have poor cooling performance you will need professional service;
Water is coming from indoor unit.
There is usually two common reasons for this problem and a few other reasons that are not too common. The most likely things that can cause water to come from the indoor unit is simply that the drain line that normally carries the water to the sanitary sewer is stopped up. This is not a major repair, but most homeowners do not feel comfortable trying to diagnose and repair this themselves. Another common reason for this complaint is that the unit is freezing up (you often can not tell that the unit is froze from the outside) and when the ice melts, it doesn't drip into the pan that normally catches water produced by the evaporator. Several things can cause freezing. You should make sure that your normal air conditioning maintenance has been done. If all of your normal maintenance has been done, and you are still leaking water from the indoor unit, you probably need a professional to diagnose what is causing the problem;
Outside will not come on.
This is a common complaint. There is a whole list of things that can cause this problem but only a few that would fall into the area of a homeowner repair. The first thing you should do is make sure that your normal air conditioning maintenance has been done. Next, check all breakers and fuses that feed power to the outdoor unit making sure to observe the safety first guidelines. If you don't feel comfortable checking electrical fuses and breakers, call for service. Make sure that you have the system switch on the thermostat set to "cool" and that the thermostat is set well below room temperature.. If you have done your regular maintenance, all breakers and fuses are good, and you are sure that the thermostat is in the "cool" position and set well below room temperature, and the unit still wont cool, you need to call for service;
Blower never shuts off.
There are several things that can cause this complaint, but only one that would fall in the category of a homeowner repair, or in this case, it is actually just homeowner training. Make sure that the fan "auto/on" switch is set to the "auto" position if you don't want the indoor fan to run all the time. In the "on" position, the fan normally operates ALL the time, whether or not there is a call for cooling. You can operate the air conditioner with the fan in either position. Most homeowners operate the fan switch in the "auto" position. If you have the fan switch in the "auto" position and the indoor fan will not shut off, then you need to call for service.
