Do I need two air handlers?

Two units allow for an easier time balancing the desired temperature in your home. Generally, one area of your home will be warmer or more difficult to cool than another. In a two-story home, the upstairs area is often warmer, as warm air rises. Having two AC units in your home can help balance out the temperature.

How do you control 2 AC units?

The first of the two popular methods to control two or more HVAC units with one thermostat is to eliminate all of the low voltage transformers in all of the HVAC units, and install one large low voltage transformer in one HVAC unit. The second method involves using a master control panel.

What is the difference between single split and multi split aircon?

A single split air conditioner has only one indoor unit connected with the outdoor compressor. Multi split ACs contain several indoor devices linked to the outdoor one.

Can 1 thermostat control 2 AC units?

Why does my house have 2 thermostats?

A single zoned system has many of the advantages of a two-unit system: The house is divided into two or more zones — in this case, upstairs and downstairs. Each zone of the house can be turned down or closed off to save energy. The thermostat in each zone controls the temperature in the zone.

How big should an air handler be for a condenser?

How does a condenser work in an AC system?

It does this by passing warm indoor air through return ducts and then over the refrigerant coil within the AC system. The condensing unit’s job is basically to transfer heat from the air outside of the building by compressing refrigerant and pumping it through its condenser coils.

How big of an air conditioner do I Need?

The manufacturers do not list the air conditioner size on the unit. The system capacity will be coded into the model number of the outdoor unit. For example, model GSX140241K is a 2 ton unit. Why? There are 12,000 Btu’s per ton. The number 24 in the model number indicates the unit is 24,000 Btu’s, divided by 12,000 Btu’s per ton, equals 2 tons.

How big is a three ton air handler?
