Written Even if you leave AC on it's high consumption compressor will turn on and off automatically. The AC fan may keep running all the time, but it's much lower in consumption.If you do manually turn AC on and off consumption will be quite the same. However running AC for short periods of time below 15 min will decrease efficiency. Probably it's best to let AC handle this on-off automatically.Understand Cycle time of air conditioners – frequently with which ac compressor turns off and on | Bijli BachaoWritten Keeping the temperature constant is most energy efficient in general. However, most window air conditioners have the temperature sensor at the air intake into the unit. Which possibly causes large temperature variations at the place where you are.Probably the best practical solution to keep the temperature at the most comfortable point where you are is the solution that some Frigidaire units have, namely to place the thermometer into the remote control.That way you can be sure the air temperature near you is constant.

See my entry "Frigidaire FRA086AT7 8,000 BTU Window-Mounted Compact Air Conditioner with Temperature Sensing Remote" here: http://3tonairconditioner.net/80...water around ac unit furnace The Blower motor on my AC unit turns off at random times while the outside unit continues to run which is causing the coil to freeze up. 4 ton complete ac unitThe blower won't come on for 30-45 minutes after the AC has been turned off, but after that it seems to turn back on fine. average cost to replace home ac unitI have been trying to track the problem down for the last couple months, but it literally only happens every 2 or 3 weeks. Last night it stopped again and I tried to just turn the fan (from the thermostat) on without luck. I took a look at the blower and it seemed to turn just fine.

I put my hand on the back of the fan motor and it wasn't hot to the touch. About 45 minutes after it turned off the blower came back and it was working normally. What could be causing this problem? I ended up calling a buddy of mine who is an HVAC tech and he pointed me in the right direction to check the fan wire on the back of the thermostat. I checked the wire and it was just hanging in the terminal. I'm pretty sure that was the cause of the problem. It makes sense because there wasn't anything wrong with the blower motor itself. The fan wire on the thermostat was in fact the problem. I fixed the connection and it has worked fine for the last 3 years. I have a ruud rheem heat pump, I had this same issue. The unit was installed in 2006. After going through the typical steps of checking air filters and electrical components on the unit, I found the wiring from the thermostat for the blower control to the control board was rusted in the wire nut. I cut the wires and stripped them back and reconnected the wires and the AC unit is running with out any trouble now.

Remember to keep it simple. HVAC service companies love these type of calls that an experienced tech can track down quickly. If you have a basic understanding of how circuits work you can fix this easily and save a bunch of cash. My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem. Check your drain lines for water run off. Make sure they are clear and then check the float for the excess water shut down reset them Also check your ground. I just ran across an intermittent blower issue (cycling on and off constantly during call for heat from the thermostat) that was due to a poor ground connection on my 120 volt to 24 volt transformer on an old Janitrol furnace.

The ground side of the 24 volt half of the transformer had 2 wires connected to it. The good one went to the mounting screw of the transformer. The bad wire went to the circuit board. It was bent over perpendicular just above the connecter, and many of the strands were broken. There was also some minor corrosion. Replacing these ground connections resulted in satisfactory operation. This was difficult to troubleshoot because operation was okay if the air filter was not in place, and the issue showed up only when an air filter was installed on the supply side (dirty or clean filters both had the intermittent problem). Thank you for asking. Your thermostat 24V wire line is lose, interrupted, broken or oxidized. Solution : disconnect old 24V line, and run new line, if this restores your blower motor function the old one was defective. Thank you and have a nice day. Cut back on usage during peak demand and save Hot summer days mean increased air conditioning use, which pushes demand for electricity to a peak.
