How is the airflow? Sounds like a clogged evaporator coil.... is it icing up?
That is what I thought as well as I do have older windows and I don't think I have the best installation in the walls. My house is not brick as well. It's the older vinyl type of siding. I would think it would still cool the house down pretty fast at night though? Currently as I type this my themostate is at 79 and the unit is coming on about every 7 min and is taking about 10 min to cool down. It's also not as high as its been here.Either that, or you simply have too much heat gain to counter-act the cooling from your unit.
Things like attic insulation, leaking windows, amount of exposure to sunlight, etc. do matter, and can make a unit operate continuously, and seem to not be up to the task of cooling.
Could you explain more about this dehumidifier technique you mentioned? I was a little loss reading your post when you mention that part. How does a dehumidifier help cool the house down? Sorry if it seems like a dumb question, but I would like to know more about this as you have peaked my interest with this one.exiledone1--So you are in Columbus and I am in Albany, say about 100 miles apart. I come to Columbus often and I know, as most of the others on this site don't, that in the last four weeks we have had one hell of an unusual heat wave with the daily temps hanging in the 98 degree+ range with nightly temps in the mid-80 degree+ range. On top of this we always have high humidity to factor into any A/C and HVAC installation. IMO-you are having a problem at this time due to a number of factors, unusual high temps around the clock, high humidity, I'm willing to bet your home is not properly insulated, and that system you describe, which I am familiar with is not one of the best that were out there when new. Suggestion: I have a dehumidifier in my home that I run every night this time of year. The tank on this unit holds five quarts of water, I can fill this tank in less than six hours starting at 10:00 P.M. EACH night at this time of year. My A/C people highly recommended doing this about four years ago and I now swear by it for helping cool the house. We do run it on weekends when we are home, and it will fill the container in less time during the day. IF you know someone who has a dehumidifier and can borrow it, try it for a couple of days to see if it helps. Based on the square footage of you gave us and the description of the home, your unit was probably sized correctly when installed. In today's world they may spec a three ton unit based on the home construction, such as lack of proper insulation, single pane glass, etc. Do all you can to reduce air loss at windows and doors. Maybe use sunblock window tint on windows that face the south side. Any little trick will help, then they all add up. Good Luck, David
......all this speculation and guessing is getting us exactly nowhere fast. we need to start at the beginning with some solid facts. you need a GOOD tech to come out and evaluate all the following: low side and high side pressures. subcooling and superheat readings. dry bulb and wet bulb airflow temps . static press readings and an accurate assesment of your actual airflow amount. Also your make and model of your ac and heating eqp't. Without all this to start with we can take guesses all day long on this or any other site & not know how to help u. also check with mr Beenthere as he is the 'real deal' when it comes to really difficult problems like this. C'mon get on it we'll help:yes:..........Jack........o yea ,,,temp drop across the evap........Could you explain more about this dehumidifier technique you mentioned?

To be honest I'm starting to think it's not just one thing, but many different factors going on at my house. I will try the tint idea, but would love to hear about this Dehumidifer technique and exactly how it works. Just for everyone knowledge my A/C does this every time around this time of the year. I agree though, it has been really hot lately!
