Why is my AC working upstairs but not downstairs?
Check for blocked or dirty registers. If they’re blocked by furniture or have dust and debris in them, it can affect air flow. Closing some vents on the first floor can help you redirect air for better circulation on the second (and beyond) floor. Check the attic.

How does dual zone AC work?
a Dual-Unit System. With a zoned system, one unit provides heating and cooling to multiple areas of your home. In a dual-unit system, you have two totally separate units that each operate a single zone with separate, unconnected thermostats.
What is the major cause of thermostat and zoning failure?
Thermostats that go wrong – Thermostats can go wrong, resulting in zones being heated and cooled at the wrong time of day or to the wrong temperature. Problems in the wiring between thermostats can cause this to stop working properly. Damaged dampers – Dampers control the airflow in systems with ducts.
Why is my AC not reaching upstairs?
Ductwork, Insulation and Seals Any type of faulty ductwork like improperly installed installation, or leaking or old ducts will force the HVAC unit to work harder to cool your home. Another issue could be that there is not enough ductwork reaching the second floor.
Can you run heat and AC at the same time?
If these two temperatures are too close together, the thermostat will be cycling continuously between heating and cooling. Most thermostats have physical interlocks that won’t allow both units to run simultaneously. With “heat pump” systems it is physically impossible because the heater and a/c are the same unit.
What is dual zone?
Summary: If you’re shopping for a car and see the term “dual-zone climate control,” it refers to a climate control system with two sets of controls: one for the driver and one for the front passenger. Some cars offer “tri-zone” or even “quad-zone” climate control. These third and fourth zones are for rear passengers.
What happens when the vent dampers get stuck?
You should be able to access and adjust them manually. Make sure all of the dampers in your home are completely open. Sometimes dampers can get stuck closed or can become loose and close on their own. This will completely obstruct the air in that particular duct and could affect the airflow in your entire house.
What is zone system air conditioning?
Single- and Multi-Zone Systems. Ductless systems can be configured with either one or multiple indoor units powered by a single exterior compressor.
What is an AC zoning system?
Zone Control Panel: The zone control panel is the main control that communicates between the dampers,thermostats and the HVAC system.
