OWNERS MANUAL 3.5 TON 13 SEER HEAT PUMP AC #RPLA042JAZ

SOURCE: 1997 Amana 2 or 2.5 ton heat pump, 13 seer - air handler only blows 4-5 min

do you have a totaline t-stat. they and some other brands have a fan recirculation setting in the installers menu.

this is assuming that this happens in addition to the heating or cooling normally

Check your filter. Make sure it is clean. Make sure the outdoor unit is operational. (power on). Clean your condenser coil with a garden hose. If possible check your evaporator coil. If it is dirty clean it. Your furnace (or air handler) blower speed should be set on high. All of your registers (supply & return) should be open and unobstructed. Check for proper thermostat settings. If none of this information solves your problem , then your units charge needs to be checked. You could be over or undercharged with freon.
Good luck......

On a heat pump the difference from heat to cool is the reversing valve.
In cooling or heating the Y1 terminal will always be energized, this is the contactor.
Depending on brand the reversing valve will either be energized in Heat or Cool. At the outdoor unit check to see if the reversing valve is getting 24 volts in cool, if not check to see if it is getting 24 volts in heating. The easiest way to check if the reversing valve is shifting, is to feel the big copper tube, (it is not the suction line on a heat pump) this is a refrigerant vapor line. It will be cold in cooling and hot in heating.
Check your thermostat installation instructions and heat pump installation instructions to determine the proper terminal designations for your heat pump and thermostat. There are some brands out there that use the B terminal as common to the 24 volt circuit, so you have to check the wiring and make sure this is not common.
If it is energized in Cool then the Y1 and O terminal will be energized. You will have 24 volts from common usually the C terminal to Y1 and O.
If it’s energized in Heat then the Y1 and B terminal should be energized. You will have 24 volts from common usually the C terminal to Y1 and B.
If you get heat when you’re calling for cooling or vice versa then switch the wire between the B and O terminals.

SOURCE: Can I mix brands/tons when installing AC unit to existing coils?

First off - the 'rule of thumb' is 600' per ton of Air Conditioning. In other words your old unit is a 2 ton unit. So - 2 tons x 600' = 1200'. As you can see if you install the 2.5 ton unit - you will be installing a AC that 'could' cool a 1500 sq ft house (2.5 x 600' =1500 sq ft.). Slightly more than what you need; and the 3.5 ton unit is 'way to big,' (3.5 x 600' = 2100 sq ft.).

Note: fyi - many in the AC business will sometimes refer to tonnage in btu's, i.e. 1 ton = 12000 btu - hence a '2 ton unit' can also be referred to as a 24000 btu unit and vice versa.

So... from the above - you can easily see that "2 tons" of Air conditioning is what is required to cool the 'average' home of 1100 sq ft. "roughly speaking."

Note: it is always best to have a professional 'size' your cooling/heating needs.

One of your questions was could you 'mix tonnage?'

The answer is 'usually you don't mix the tonnage of your outside/inside units.' However, professionals sometimes do (mix the tonnage) in certain situations, and installing a 2.5 ton outside unit with an existing 2 ton inside unit is often done, however, there are some 'tech issues' here and - I would "again" recommend that you call a Service Tech to help you with the sizing/mixing of your cooling/heating needs.

hope this has helped

SOURCE: LOW VOLTAGE WIRING CONNECTIONS BETWEEN

Hi!!
The Rite Temp thermostat can be wired many in ways according to your unit's needs, I would like to send you an installation guide showing the different configurations, then you tell me which and how many wires come from the heat pump and we go from there. For this I need an email address to send it to. Thanks
