What Mission Viejo Homeowners Can Check First

When the Air Conditioner Runs but Doesn't Cool

If the AC runs without bringing the temperature down, start with the simple checks: confirm the thermostat is set to cool, replace a dirty filter and make sure the outdoor unit isn't blocked by plants or debris. Ice on the refrigerant lines, warm air from the vents with the system running, or a unit that runs constantly usually needs a technician, because those signs can point to low refrigerant, a failing capacitor or a dirty coil.

A Running Toilet Wastes More Water Than You Think

A toilet that refills on its own or keeps running after a flush is usually leaking past a worn flapper or a fill valve that's set too high. To check, put a few drops of food coloring in the tank and wait 15 minutes without flushing. If color appears in the bowl, the flapper is leaking. These parts are inexpensive, and fixing them early keeps the water bill in check.
