Does an air handler and condenser have to match?
The short answer is that a handler and condenser can be different brands and the unit will function properly. Ideally, it is better to match the same brand of condenser and handler if possible, and have them both replaced together.
Will a 3 ton condenser work with a 4 ton coil?
Registered. I have a 3 ton condenser with a 4 ton coil and I haven’t had any issues with it. I do live in a dry climate, so it’s not an issue. If you live in a more humid area, I’d suggest not over sizing the coil.
Can a 4 ton EVAP coil run a 3 ton condenser?
For instance, a 4 ton evap coil on a 3 ton condenser causes longer run times. Thereby increasing the air contact time with the coil. As long as the airflow is set for the smaller condenser then you are ok. So you would set the fan in the 4 ton evap to flow at a 3 ton equivalent CFM. 0 · Share on Google+.
Can a 5 ton furnace work with a 3 ton condenser?
In my opinion (don’t) The 5 ton furnace will have a to high a CFM across the coil for proper heat transfer. If the blower motor was a multiple speed motor and was able to match the CFM for a 3 ton condenser it perhaps might work.
Can a 4 ton furnace be used as an oversize coil?
I am replacing condenser and coil, keeping my current furnace. I currently have a 4 ton unit , which is oversized for my house. One contractor wants to use a 4 ton coil with a 3.5 ton condenser, citing better airflow with my furnace if he installs the larger coil. Any one know of any pros or cons to this?
How big of an evaporator coil do I Need?
The larger the tonnage, the more heat it can remove. Most residential AC sizing varies from 1 to 5 tons. So, for example, a 2-ton evaporator coil should only be paired with a 2-ton condenser coil. Now let’s look at some problems that can pop up when these two coils don’t match in size.

Can a 5 ton air handler work with a 4 ton condenser?
The 5 ton Rheem air handler will work with MOST 4 ton condensers if the correct metering device for the condenser is used. Since you specify that the condenser is variable speed then perhaps it requires communication to the indoor unit and thermostat.
