Recently my 18 year old 10 Seer 3 Ton Tempstar system sprung a freon leak outside. It was decided that it needed to be replaced but a replacement 10 Seer could not be found so I had to get a 13 Seer 3 Ton system which meant the inside coils/furnace also had to be replaced with compatible system. I was fine with that since the system was on its last leg and the 13 Seer would save me some money in the long run to cool my 1600 SqF house.
So I had a new system installed inside and out (Concord 80 Plus Furnace) after two days the house was just not cooling right. In the heat of the summer 90-95F here, my old system blew 52-55F during the day and 45F at night (I have a guage 1 inch out from the vent) the new system blows 60F-62F all day and it feels like 75 about a foot from the vent. The wind speed is about 5.5 mph right out of the vent. I have my air set to 71 and the new system runs all day and the temperture just climbs 1 degree every 1.5 hours or so to about 78 in the heat of the day and won't get to back to 71 until around midnight when the outside temp is about 74. Were my old system would run 20 min, shut off for about 10 min and then run for another 20 and so on all day keeping the house at 71 all day.
I had the tech come out and look at the system and he said it was about
5% low on freon filled it up and said it was working at optimal performance. He tells me it won't ever be able to get below 72-74 in my house when it is 95 outside?!?! Were as with my old system I could freeze you out of my house even when it was 95 outside?!?! The new system runs all day to maintain 72 degrees even if it is only 83F outside.Now 3 weeks have gone by and today the system has completly iced over. The tech is coming back out tommorow but I know he is just going to say it has a feon leak, fix the leak and then turn back on the crappy system which will run all day an still not get below 77. The back of the house it is like 80+F.
I feel like this guy doesn't have a clue, someone help me to tell him what to look for, or what to check because this can't be right. The air should be colder than 62F 1 inch from the vent?? and 78F in my house when running all day. Also, the air that is coming out doesn't feel crip and cold more like damp and cold like the humidity is not being removed.
I have also gotten my Energy Bill and on my 10Seer it was $240 and on the 13 Seer the bill is now $265.
Maybe something isn't calibrated like wrong load calculations, or expansion valves, variable air fan or blower speed? I know squat about AC so I have nothing to stand on when he says "This system is running great, thanks for the $5,000 and have a Hot summer."
Thanks in Advance, sorry for the long post.
