You may need to call a service rep..Sounds like things are siezing up or it needs freon....Are you having brown-outs in your area? If so that could be why..the electrical company does that to save on energy.
When you say "the switch will blow", do you mean the breaker? A thermostat cant cause the breaker to trip. Being low on refrigerant could cause the breaker to trip when you run the A/C longer.
It may vary from company to company. The most important points are what
we consider the most important. There may be more done while on the job
at no extra cost, but this list contains every thing that is done every
time by us.

• Calibrate thermostat
• Replace or clean filters
• Clean and adjust blower components
• Lubricate all moving parts
• Measure temperature rise
• Check combustion efficiency with digital
It is not dangerous. Is it cooling your house? If it is not condensating or producing water like it should then you have a couple of problems, an airflow issue or too much refrigerant in your system! When was the last time you had it serviced?
This could be a serious problem with the compressor. However, it could be a capacitor or fan motor. Best to call in a professional.
We recommend that electrical appliances such as air conditioners be worked on by ONLY TRAINED TECHNICIANS. The problem you describe may be a bad motor or capacitor. If its a dual cap for both the compressor and fan look for bulging at the top of the cap. Typical sizing for A/C is 20-80 micro farad for compressors and 5-10 MC for fan motors at 370-440 VAN. You must match the existing micro farad to work properly.
This is a sign of a coil freeze up and thaw. It can be caused by a number of reasons that will require a service technician to help you with. You can check for a very dirty furnace filter (airflow) and a clog or problem with the drain from the coil. If the unit outside is extremely dirty, it will also freeze up, it can be cleaned with a regular garden hose. If its none of these, your system may be low on refrigerant and a technician should attend.
If you are referring to the area outside the coil that is on the inside of the house, the problem is either lack of air flow i.e., dirty air filter, blower wheel, too many registers closed, etc. Or lack of refrigerant flow which is usually cause by a freon leak, but less often by a restriction of refrigerant flow. The coil on the outside unit would only freeze if it were a heat pump, and then only in the winter time.
Your coil could be dirty inside between the fins, or your filter needs to changed, there are a few other things that could cause that besides low freon. It could be your outdoor unit is not shutting off when the indoor unit does, also you should not run it if it is 65 degrees outside, because its colder outside than the air conditioner can cool the inside so the unit will not cycle off and will ice up.
