not very well. a 4 ton system needs about 1600 cfm to provide it's full capacity of cooling. a 3 ton furnace puts out about 1200 cfm. in addition, the evap coil typically attached to the furnace needs to match the tonnage of the outdoor unit. so, the evap coil must be 4 tons. If you currently have a 3 ton furnace and evap coil, the system will not work, and you will most likely ruin the compressor in the outdoor unit.

Half way between the the condenser and air handler, in the liquid line.


Can use 7 ton condenser unit hook up the 6 ton evaporator?

you can probably get away with that just make sure you have an expansion valve on the evaporator. An expansion valve will keep liquid from getting back to the compressor.


What is the best gas furnace and how much should it cost?

It all depends on the efficiency of the unit you want (80%, 92%, 95% etc.), how big the unit is, and what brand you're going with. I recently replaced my gas furnace. We have a 3 ton unit for our house. We went with the 95% eff. unit because we were able to get a tax credit, it cost us a hair below $2500. The 80% unit was $1,400. The 92% unit was $1,800.="h2headingh2"style="color:rgb(0,0,0);"name="it_all_depends_on_the_efficiency_of_the_unit_you_want_(80%,_92%,_95%_etc.),_how_big_the_unit_is,_and_what_brand_you're_going_with._i_recently_replaced_my_gas_furnace._we_have_a_3_ton_unit_for_our_house._we_went_with_the_95%_eff._unit_because_we_were_able_to_get_a_tax_credit,it_cost_us_a_hair_below$2500._the_80%unit_was$1,400._the_92%unit_was$1,800.">


What is the meaning of standard ton of refrigeration?

A Ton is the measurement of the amount of heat required to melt one ton of ice. It is also 12,000 BTU (British Thermal Unit) So the Ton is a measurement of the amount of heat that the refrigeration system can remove.


What are units for work?

Work is defined as Force applied over a distance i.e. W=F*x. The units are, therefore, 1Newton*1meter=1Joule. Work is measured in Joules! Work is energy. Any unit used for energy is a perfectly good unit for describing work. The SI unit is the joule. Other examples include foot-pound, watt-second, kilowatt-hour, dyne-centimeter, ton-furlong, horsepower-hour, etc.

Can a 4 ton indoor evaporation unit be matched to a 3 ton condenser unit to make it more efficient?

No. It will be less efficient.


Have a 5 ton condenser with a 5 ton coil have a 3 ton drive furnace any way this will work or will you have to get a 5 ton drive furnace?

You may be able to turn up the blower speed but you will probably still not get the appropriate cfm. You may be able to swap out the blower but you may run into problems with fitting the new one in place or the proper sizing of the return and supply duct work.

Can you install a 3.5 ton condenser on a 3 ton evaporator?

Installing a 3 1/2 ton condenser on a 3 tr evaporator will not function properly. There isn't enough evaporator coil surface area to absorb heat and vaporize refrigerant liquid for its return back to the condenser compressor. What can be done is a 3 ton condenser unit with a 3 1/2 evaporator coil.


Do you have to have a 4 ton coil for a 4 ton ac unit?

The rating is technically a minimum. You could use a larger coil and have it work. But if its a Evaporator coil it will need to be matched on the far end with a similar or larger condenser coil. If the Condenser coil is larger it will probably just take a little more refrigerant.


Will a 4 ton condenser work with a 3 ton furnace?

It may run. But not efficiently or to capacity as there will probably not be enough air flow.You also run the risk of ruining the compressor by flooding it, as residential a/c units are notorious for not having hi and low pressure cut-out switches.


5 ton condenser with a 3 ton drive furnace is there any way to fix this without replacing the furnace with a 5 ton drive?

No easy answer with the information given. You might be able to increase the blower speed but that probable wont get you enough air anyways. You might be able change the blower depending on your furnace. Depending on the evaporator coil 3 or 5 ton you either wont remove the proper amount of moisture from the air(the biggest part of what makes you feel cool) or there will not be enough air blowing over the coil and it will freeze up. Technically could put a freeze switch to turn of the condenser. Most likely you will wear out the condenser quicker then it should.


What size condensor for 1800 square foot home?

A condenser is typically installed based on 400 square feet per (1) ton. That is, in a dwelling of 1800 square feet, a 4 & 1/2 ton unit, (for air conditioning), will be needed. Any less and the condenser will have to work too hard. Much more and the condenser will over work, (due to start-up and cool down energy overlapping, as well as the excess energy required to run the larger unit), thereby wasting money.
