We have a Lantana that is 6 months old. When the A/C first comes on we get a "burst" of warm air then the cool air fron the A/C. Is the air in duct work getting that hot between the cycle? The duct work is insulated, but maybe not enough! Anybody else have this problem?

Don't know because my AC is on pretty much all the time right now.

The ducts run through the attic and it gets very hot up there. The ducts will heat up when the AC is off and you will get a burst of hot air initially on start up. I doubt you could put enough insulation around the ducts to prevent this.

Ditto. Attics can get up to 150 degrees in the summer depending on the color of your roof.

Yes, we get this too. Our ranch is 6 years old; we have a Trane. Makes me think the heat is coming on. Weird, huh?

You'll proably notice in the winter heating season that you'll get cold air coming from the vents before you feel warm air...it's just the temperature of the static air in the ducts. It is what it is.

for the best performance and maintenance of your system try running the fan constantly (switch from auto to on). You will find the elimination of the hot rush of air. Circulation of the cooled air continues after the thermostat shuts off the compressor (when it reaches the set temp), hence extends the time until the thermostat kicks the compressor on for the next cooling cycle.

Many folks do not do this because they think it adds cost. Well it does but no more than leaving lights on in the house....which can be out weighed by the benefits.

Others will be concerned that the motor will wear out....very unlikely.

If you have ceiling fans they should be running 24/7 as well. You will not wear these fans out and the cost is insignificant to keep them running.

Doing the above results in a much more consistent temp throughout the house....try it. It will also be filtering more of the air you breath as well.

The fans in our 8 year old home have never been turned off.

To add to billethkid's post: Just remember to check/change your furnace filter more often.

Seems to help! Will compare cost with my next SECO bill.
