My home A/C stopped producing condensation. Its still cold, but it runs longer than it used to. Repair time?
Question:
Answers:
Time to recharge your A/C...Part of regular maintenance..
If the air is dry with very little humidity, there won't be much condensation being made.
Check the coil in the frunace and see if it's iced up, if so then you are low on freon.
The amount of condensation produced is related to the relative humidity, but if it seems to be taking longer to cool,, you should arrange for a service call. Before you call anyone, check your air filter, I can't tell you how many 59 cent filters I change every week, the service calls for filters pay my mortgage...LOL Oh, and by the way, in no way is charging your system regular maintenance,, if it needs freon, it has a leak. Plain and simple.
check your temperature sensor (small copper rod-like attached to the grille), it may be out of its original place. it is located on the inside unit.
it determines the temperature of your AC wether it needs to be shut down due to cold temperature, or the other way around
Not necessarily, if the air isnt that dense, there wont be that much condensate produced. The time for repair is when it doesnt cool or take too long to make temperature. Until then, dont sweat it, you should be good if the filters have been kept up.
Oh, and to the top contributor. If you think recharging a unit is just something that has to be done normally, a shady tech will make a killing on people like you.
Education saves money.
In reality, many other questions need to be answered. First of all, the cooling part of a residential cooling system is desigened to work with an outdoor temp of 95 F., at 50% humidity, and an indoor temp of 75 F. Unless you live in the driest areas in the world, the evaporator coil will be getting cold enough to cause condensation on the coil. The only way the coil would not be getting condensation formation is in zero humidity or a malfuntioning system. It could be that the refrigerant charge is low and causing the compressor to kick out on an internal thermal overload or there could be a low pressure switch that is opening and auo resetting. The condenser coil ouside could be dirty and causing a high pressure switch to open, shutting off the compressor. A technician will clean the condenser coil, clean/replace air filter, and check the refrigerant charge as well as a leak check as a part of a standard service call. I would call someone soon before it gets really hot and it could take a week for service. For the most part, beyond cleaning the condenser coil outside and replacing the air filter regularly, there is not much the average homeowner can realisticlly service on the system.
