We are renting a 2 year old house, approx. 1600 sq. ft, 1 level. It has a ComfortMaker unit that I think is a 3 ton. Air flow is great in the living room and kitchen, very powerful, so much so that when the unit kicks on you have to turn up the volume on the TV.
But in the two smaller bedrooms (which are actually closest to the HVAC unit), there is very little air flow and those rooms are about 8 degrees hotter than the others. Even though we have dark curtains on the windows and keep the blinds closed, the system runs NON STOP from 8 AM - 11:30 PM.
Thermostat is set at 72 degrees. The temp. outside has been from 85 - 95 degrees. We live in SC, so it is only going to get worse over the next few months. Our energy bill for April was already almost $200. Had the freon checked and the tech says it is OK. Any ideas? My toddler cannot sleep b/c her room is so hot.
Have changed the air filter once per month. I am using a 3M allergen filter.
Any ideas on what to do next? We have sliding glass doors on the back side of the house, and from 1:00 - sundown the sun is hitting those doors. We keep the vertical blinds closed, but you can feel the heat coming in. Is this a major factor in the house being several degrees hotter than the thermostat is set for? (i.e. set for 72, but is currently reading 76).
Thanks so much for any advice you can offer. I want to be educated when I call someone out here to look at it. I don't want to waste time or money.
