I have a four ton package heat pump on my home. My home only calls for a three ton. I currently have a unit that cycles every few minutes. If i were to replace the blower fan to a three ton fan, 1. would i have more or less of a cycling issue. 2 will there be a possible frozen coil issue. 3 what else could go wrong?
A better solution than undersizing the fan (which would decrease your airflow and probably not satisfy the household as well) would be to change the deadband in your thermostat. (Disclaimer: best solution is always to have a properly sized unit!). Most programmable thermostats have a "deadband" that can be programmed in. This deadband is a certain number of degrees, in heating and/or cooling, where the thermostat will not call the system even though you have reached a threshold temperature. I.e. System is set to call for cooling at 76 degrees. there is a 3 degree deadband. When the Tstat reads 76 it will add the deadband (3) and not call for cooling until the room temperature is 79. This will prevent the compressor from cycling quite so much. Adjust your setpoint temperatures (i.e.76) with the deadband in mind and you can arrive at a range that is comfortable and reduces compressor cycling. Good Luck!

12,000 but/ton. If the 101 in your model is their tonnage (101÷12=8.4. its a 8 1/2 ton (5 ton and a 3 1/2 ton combined). That's probably it or very close. I could not look it up cause I don't know the maker of the unit.
Hi, the tonnage of this unit is a 024, which is a 2 ton. There are 12, btu's per ton of cooling, and this number will always be in the model number of the unit. If it were a 21/2 ton it would say 030, 3 ton is 036 and so on. Please feel free to rate me, and I thank you very much. Sincerely, Shastalaker7 A/C, & Heating Contractor
Hello, the tonnage on this unit is a 3 ton unit. Your model number tells you. The 036 is the tonnage. There are 12,000 btu's per ton, so 36 divided by 3 =12 or in this case 12,000 btu's. Sincerely, Shastalaker7 A/C, & Heating Contractor
This is a 3 and 1/2 ton unit. The 042 in the model number is the tonnage of your carrier unit. AC tonnage is based on 12,000 btu per ton. 12,000.....1 ton 18,000.....1 and 1/2 ton 24,000.....2 ton 30,000.....2 and 1/2 ton 36,000.....3 ton 42,000.....3 and 1/2 ton 48,000.....4 ton 60,000.....5 ton. There is no 4 and 1/2 ton unit.
Hi, to find out the tonnage of your unit in b. t. u.'s, look at the 08 in your model number. There are 12,000 btu's per ton of cooling. You have a window /wall unit, and according to the model # 08 is not a 1/2 ton or a 1 ton, but a 3/4 ton unit or 8,000 btu's if indeed this is the correct model number. Most units we come across are in btus as 06 which is 1/2 ton, 12,000 is 1 ton, 018 is 1 1/2 ton and on up with a properly matched indoor coil. Your unit is a package window unit, so both coils are equal. Sincerely, Shastalaker7 A/C, & Heating Contractor
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.
Yes it is a three ton unit, there is no square footage method for determining the correct size for an a/c or heat system, a proper heat load must be performed to verify the heat gain and loss of the structure. Also, if the ASHRAE method was utilized for sizing your sytem them it is sized to keep the structure 78 degrees inside with a 98 degree outdoor temperature. (the thought process that was explained to me was that most areas only spend a couple of hundred hours above 98 degrees) In my mind that is when I want my a/c the most! and I want it 72 inside my house. For my area I use 100 outside and 70 inside for my load calcs, many years ago when I first got out of school , I used the "standard conditions" after replacceing a few units for free, and a few unhappy customers I moved to the paramenters that I gave above. Probably not the answer you wanted...(sorry)
