We have a fireplace with forced air We are having problem keeping the humidity in our house we run a humidifier all the time. Our house is 1600 sqft the humidifier is an floor unit for a 2400 sqft

Consider installing a whole-house humidifier onto your furnace. Those portable units are rarely adequate for anything more than a single room.

I have a 4T residential heat pump on a 2300 sqft house. The unit will run all day and keep the house nice and cool. then around 5 - 6pm when the outside cools down the unit stops cooling but stays on

I can't answer your question. I just wanted to mention a slightly different way of looking at things. Manufacturers increasingly over the last few decades tend to be accountant -led and therefore very concerned with profitability. This means manufacturers do not make things better than they absolutely need to be, taking into account the projected market price and that of competitors.

These days equipment is built down to a price and possibly a target weight/size and to be capable of a certain duty cycle. The duty cycle of some domestic equipment is appallingly low and even versions aimed at a business market is surprisingly low.

Industrially rated equipment tends to be the only equipment that is designed and built for a 100% duty cycle. It would be reasonable to expect any equipment that is designed and built for a 100% duty cycle, regardless of the destination market, would cost at least as much as industrially rated equipment. Domestic equipment is often considerably cheaper than industrial or business equipment and the lower price tends to manifest as a reduced duty cycle and/or a reduced lifespan.

It could be wise to adjust your expectations somewhat...

What size central a/c,heater do I need to cool-heat a 2400 sq/ft house in west Texas

You haven't included enough information to give you an accurate number. Things to consider are:
- R value of attic and wall insulation
-cubic footage of the living area
-are the windows single double or triple paned... low E ?
-how many hours of direct sun?
-how many points of return air do you have?

Its better to over size your system than to undersize.

One more thing to consider.... heat rises, cooled air falls and if you want to run your ducting under the house? insulate the crawlspace walls.

I would like to know how many square feet a Model # BRCQ0421BD Serial # 990905429 Coleman Central Air Conditioning Unit will cover. The unit supply is 208-230V 1 PH 60 Hz 10.8 RLA 97 LRA.

The Old Rule of Thumb is 400 square feet per ton, but you really need to do a heat load calculation to be safe. A lot of windows on the west or south side of the house will really increase your load and you may need a lot larger unit. Insulation also changes your load so you may be able to cool a larger area. You may be able to get the Heat Load Calculation Form either online or from Johnstone supply. They are on the internet.

Wont heat a 1,500 sqft one story home..air is cold by time gets to far end of home..gas pack 3 years old

One thing you can do is slow the blower down, this
will give you greater temperature rise and heat evenly.
The length of the home is what is needed.

Its possible that you need to have dampers installed in your ductwork or you need a booster fan installed
on the ductwork that feeds that side of the house.

My guess is that you need 80,000 btu heat output
to come close to heat the house. Since ductwork is
sized for cooling you would need 36,000 Btu Cooling
output. More information is needed
