I was wrong it is suppose to be a 3.5 ton. i looked at my quote. But i still say something is wrong. The tech just left and he took out a strip (he said there are 3 and he took out 1 to see if it helped) he said the only thing he could see was that it was cutting off to quick after cutting on. and supposedly taking out the strip should help. the temperature right now is 74 and i turned the heat on (to check it out) to 77 about 10 minutes ago and it hasn't come on yet.
He told me it is all electric. i don't have a heat pump.
The previous unit was a carrier 561AJX042000 (C.U.)it also says Nanleg 15 KW (FM) #RCAB045-500. The writing is hard to read.
Checked the model #'s on actual units and the outside unit is #24APA542A300 - Puron. and the unit in the attic is #FY4ANF042.
When it comes on i will see if the outside unit is running as someone asked.
You have an AC condenser when you need the sister mdl in a heat pump condenser.
Someone has really screwed up here, either you or your dealer.
Genuinely sorry for your trouble.
Did you recieve a new thermostat with your system?
What type of thermostat do you have Digital or Analog?
What are the initials of the installing company and what part of town are you in?
Seems very odd that the t'stat is set on 77 it is 74 in the house and the heat has not come on yet!
Electric resistive heat has a COP = 1 It's doesn't matter if you are using 1000 electric hairdryers to heat the house. Electric resistive heat is 100% efficient. Either you are just not used to electric heating bills as opposed to a heat pump or the outside unit is cooling while the strips are on. One of the two.
The tech just left and he took out a strip (he said there are 3 and he took out 1 to see if it helped) he said the only thing he could see was that it was cutting off to quick after cutting on.
I tend to believe the former.
what do you mean "sister mdl in a heat pump condenser"? As i said i know nothing about ac/heat. we just needed a new system and so i called and got quotes, the company that installed the unit is the people that are suppose to know what they are doing, not me. i told them i wanted a new energy efficient A/c & heat not one that was gonna double my electric bill and make it to where the temperature is never comfortable.
As i said i have called them out i can't count how many times since the install because it hasn't seemed to have ever run right. They keep telling me nothing is wrong.
Why don't you try this.
He's in your area and has offered to help. I would take the offer if i were you

Tamayra instead of looking at the dollar amount on your bill look at the kiowatt usage. Rates have gone up and the last few months have been colder this winter than last winter.
Tamayras......this poster "classical" is a professional member here. He lives in your area. He has asked you to look under his profile for his webpage and give him a call. He has offered to help you. What more could you ask for?
You have an AC condenser that cools only when you need a heat pump condenser that both cools for air conditioning in the summer and heats for winter heating. It's that simple. Maybe a communication issue with your dealer. But that's the problem in a nutshell.
This is not really true, until recently heat pumps have been a very poor option for the Houston market. Even now unless you are going to go to the added expense of installing an ECM her system still makes good sense.

Our winters are so mild it can sometimes be a hard option to recomend.
I assume you technician is competent enough to check refrigerant charge. If charge is okay then you may have a size issue. It is quite possible the carrier salesman sold you a unit sized to satisfy your heating load. If you need only a 2.5 ton (cooling) and they installed a 3.5 ton(cooling) unit then the compressor will come on and off quickly. The main reason is because your compressor is too big to meet the load...the compressor does not modulate down to 2.5 tons. Excessive compressor cycling will lead to the compressor failing prematurely.

What happens here is that the compressor is able to cool the air temp to the desired temperature but not on long enough to dehumidify, to remove moisture from the air. The compressor needs to be on longer to dry out the air. Eventually you will get cold but damp air in your house and quite possibly mold. The only solution for an oversized condensing unit is to have them install a "Rawal APR valve". www.rawal.com... the dude who owns this company is turd but he makes a good device that works. Compressors like to work...which is why the french don't make one. You may want to watch your compressor, listen for how many times in a fifteen minute period it comes on and off.
Classical, she said her electric bill doubled. I wonder what temp she kept it at before.
Classical your wrong. We are in the midst of global warming, AllGore said so. You must be delierious from the heat.
