First, check to see if your thermostat has batteries. If so be certain that the batteries are good batteries alkaline batteries. If your batteries are checking well, proceed to the next step.
Check your breakers. By flipping the breakers off and then back on can reset the electronics. Make sure you start with the outside unit first and then the inside. If the unit is still not blowing air verify if the outside unit is working. If both units are not functioning you might have a sensor switch in your drain line that might be tripped because of algae buildup. Please call us for a thorough drain line cleaning. If all the algae are not addressed the problem will continue to persist and cause system breakdown and possibly permanent damage.
If your unit is operating outside and not inside it’s likely you have an electrical issue and you should call us to have a certified technician check the system’s functions.
