Alright, here's the deal, and it may end up being long, so bear with me! Quick questions are at the bottom if you don't want to read through all of this :) Wife and I just bought a new house, 2 story,
2100 sq. feet. Master bedroom downstairs, 2 bedrooms, bonus room upstairs. 3.5 ton centrail air unit. Upstairs wasn't cooling very well, and no air was coming out of the vent in the master bedroom. Called American Heating and Cooling. They came out, found the damper for the bedroom was closed. They opened it...nice cold air. The tech didn't feel like the dampers were closed in the upstairs room as he could feel air coming from them. The vents in the upstairs rooms are in the ceiling. The rec room vents (which are on the opposite side of the house from the unit) do blow cold air, but the two bedrooms aren't blowing very cold air. Could this also be a damper issue? Should I have had him go in the attic to check? Where exactly would the dampers be? He went under the house to open the one for the bedroom downstairs....would the upstairs dampers be on the trunk under the house right next to where it comes out of the unit like the downstairs vents? Does each vent have a damper control? I'm assuming so but wanted to make sure.Now, here's the next problem. He discovered a freon leak in the evaporator coil. The unit (4 year old Bryant) is still under warranty, but the labor was going to be $368. Instead of having him do it, we are going to utilize the warranty that the seller purchased for us when we bought the house last week. The warranty company sent their tech out yesterday, and he did verify that there is indeed a leak in the coil and it would have to be replaced. So we're waiting one the part. Does anyone have any experience with Old Republic Home Warranty? That's who we have. On our last house we had AHS, and had a major problem with them when we had to use it to replace the entire unit in our last house. Hopefully someone can let me know OR is better to deal with. So, in summary, my questions are:
1) Is this unit big enough for the house? Both techs have said yes, but the fact that the return in downstairs and so is the thermostat, I may have problems in keeping both floors at the same temp. Is this true? 2) Would low freon and an evaporator coil leak be the cause of the lack of cold air coming from some of the upstairs vents? The vents downstairs are cold even with the low freon and leak. 3) Are the dampers to the vents all located under the house on the trunk where it connects to the unit, or will I have to crawl through the attic to check on the upstairs dampers?Thanks for any help!!!
