I want to purchase a 4 ton 14 seer AC for my home in Fl. I have quotes on Trane, Carrier and Amana. How do I compare these 3 units as to which one is the best and why

Please post the full model numbers of both the indoor and outdoor units as provided on the 3 quotes. It would be helpful if you provided what is included in each quote (ductwork, lineset, thermostat, warranty, etc.) as well as each price to accurately compare the quotes.

How was sizing determined? Hopefully not merely going off the size of the unit being replaced.

Is this quote for a furnace/AC or a heat pump? Either way it seems like an excellent price for a Carrier 3.5 ton with a 14.5 SEER rating. As far as the humidifier goes, if you have an extremely dry winter in your area, then go for it.

The equipment you posted is a approved match on the AHRI directory. Out of curiosity I also entered the 5 ton CBA38MV-060-230 model. Here are the results: The numbers seem strange, but the 4 ton air handler produces 57,000 BTU of cooling with a 18 SEER and 11.2 EER. The 5 ton air handler only achieves 55,000 BTU of cooling wit 17 SEER and 10.5 EER. In this case the 4 ton air handler outperforms the 5 ton model and is more efficient. I imagine the 4 ton costs less than the 5 ton. You Lennox contractor has done his homework by offering the better equipment. If you have more questions I suggest you start a new posting rather than tagging onto this old one.

"Bad" power factor does NOT increase the REAL actual power consumed, "REAL" or actual power is measured in kW, that's all you use and that's what you're charged for. If device(CFL) uses 80% of the power going into it, the power factor is 80%. Power factor is the Real Power divided by the Apparent Power. For example, 98 kW (Real Power) ÷ 100 kVA (Apparent Power) = 98%. Again, residential customers are charged only for the REAL Power actually used, not the Apparent Power sent, That's not our problem, it is for the utility, believe me if it was a significant amount we would be billed a fee for power factor. Factories are billed for power factor,power factor does require the utility to compensate a little bit, it's at a far, far lower level than would be the case if they had to make up the total difference between the actual power factor and a power factor of 1.We can and do ignore the power factor issues in residential, there would be no way to diagnose anything if no rules applied or reality unable to be qualified. To prove this point, I set up an experiment with CFLs vs. incandescent lights (resistive loads with a power factor of 1.0), and measured watts and volt-amperes delivered by my inverter. Then I measured the amps from my power source, a bank of L-16 batteries, which are DC sources wise to the tricks of reactive power....The low power factor did not require the batteries (or the utility) to produce any extra energy.

So there is no "correct" amount of tons needed per square foot. It should be based on load calculations based on orientation and shade and location. For a mobile home, there is no right answer. If the house can stay at 74 degrees on a hot day then the unit is big enough. The usual design temp is 75 so getting to 74 is a luxury. Now if some days, the temp can't get below 80 then you have an issue. You don't actually mention what the interior temp is. I am guessing that it isn't cold enough for you. I am going to guess that it isn't really the a/c's fault. I think your infiltration or insulation is the problem. For the amount of windows that I've usually seen on a mobile home, 2 tons should be fine for a new home.

None of the quotes include a variable-speed indoor unit, which I would recommend (of course I can't tell for the Rheem). Brand isn't as important as finding a competent installer to do the work! The Amana also does not use the new refrigerant; it uses freon (R-22). I'd ask for an upgrade price to a variable-speed blower (Amana: AEPF series blower, Trane: 4TEE series blower, Carrier: FV4 series blower, and Rheem: RHKL series blower). Prices sound reasonable. Did the old 4-ton unit cool okay, since that's the replacement size? Things like new lineset, ductwork modifications, new thermostat, etc. would be helpful to know for each quote.

Here are the efficiencies from what I could pull up:
Amana: 12.2 EER, 14 SEER
Trane: 11.2 EER, 13.5 SEER (due to no variable-speed blower)
Carrier: 11.5 EER, 14 SEER

here are the performance numbers I found from the AHRI Directory. Of course, I didn't have the Rheem model numbers. While you said 5 ton in the subject, I assume you meant four ton. I agree with Ryan about the var speed air handler. You should be aware the Amana system is rated at only 45,500 BTUs which is shy of 2500 BTUs of being a full four tons. This raises a question if you need the cooling BTUs.
