SANDI OR MIKE Posted May 20, 2015 Report Share Posted May 20, 2015 Above system was put in new 2004 and just bought this house in 2014. Anywhoo, when we hit the 85 or higher temp, the ac system just keeps running for one and a half hours just to cycle. Both ac repair guys said we have adequate freon and system is good. The last guy said to put more ceiling fans. The problem happens when we have high humidity which is pretty much all summer on the gulfcoast. Note: If we raise temp to 79 or 80, it will cycle but at 78, it just runs! ?????? Link to comment Share on other sites More sharing options...
Jim Katen Posted May 20, 2015 Report Share Posted May 20, 2015 The system might just be undersized. If it's not, then you've got a disconnected duct somewhere. Link to comment Share on other sites More sharing options...
Marc Posted May 20, 2015 Report Share Posted May 20, 2015 How big is the house? Marc Link to comment Share on other sites More sharing options...
SANDI OR MIKE Posted May 21, 2015 Author Report Share Posted May 21, 2015 The house is 1460 ft in living space with 12 foot ceilings in the living and kitchen area! My husband seems to agree the unit is not big enough! We have a home warranty to repair the items in the house, would this be covered under warranty if we had to replace the system!

Scottpat Posted May 21, 2015 Report Share Posted May 21, 2015 A 2 1/2 ton unit in Gulfport on a 1500sf home with 12' ceilings is on the small side, IMVHO?. Was the home built in 2004 or is it older? No a warranty would not cover an undersized system. Link to comment Share on other sites More sharing options...
SANDI OR MIKE Posted May 21, 2015 Author Report Share Posted May 21, 2015 Yes, home built in 2004! We just bought this house in November so this is our first summer. When temperatures are under 80, system works like a charm! With all the humidity we have now, this is when the problem started. The high ceilings are only in the living/kitchen area. Bedrooms have regular ceiling and master has a tray! Link to comment Share on other sites More sharing options...
Marc Posted May 21, 2015 Report Share Posted May 21, 2015 I agree with Scott. 2 1/2 tons on a 1460SF house, built 2004 in Gulfport is on the lean, lean side. You can change it to a larger size or just leave and buy a 15,000 btu/hr window unit. Stick it in any room that has a register and use it like that until the central system is old enough to replace it. Keep the thermostat on the window unit a little lower than the central thermostat, so the central still regulates temperature. The window unit option would benefit you when the hurricanes come and the electricity goes out. A 4 KW power plant will power that window unit easily and leave additional room for the fridge, all lights, all general purpose receptacles, tv and other small loads.
