 and that is have your HVAC system serviced annually. This will save you money. Get on a maintenance plan, take care of it, get them to clean out the coils, make sure everything's going good. If you've got an older system, they'll make sure the capacitor that starts the motor works correctly, isn't swollen up. That way, when it gets super hot, it doesn't cut out on you. Most of the time, a good technician can predict that from happening.
