Air Conditioning the Lanai

[waltwl]

Looking to extent one of my air condition ducks out to my Lanai. Anyone know of someone that does this kind of work?

You would want to make sure that your current air conditioning system could handle it. To do it properly, a Manual J should be done. You do not want to compromise your entire system by adding a duct without making sure it can handle the additional load.

If you find that your present system cannot handle the additional load, you may want to consider a mini-split system.

Also...neighbors did this and when it came time for them to sell, the inspector didn't pass it. You may need to check with the "powers that be" before doing this as well.

What if the installing AC company approved and did the job?

Your current HVAC system will not have enough capacity to cool an addition room.

On what ground did the inspector "not pass it"? Shoddy workmanship? wrong number of vents? bad duct work?

Extending the AC to your Lanai also increases the square footage of your home and thus increases your property taxes. Consider an external vented AC unit available from Lowes or Home Depot for around $350-$400 dollars.

Frank,

What is a manual J. If your present unit is over sized for your present S/F would vents work?

Our Lani has been enclosed for a year now
We just leave our sliding doors open turn ceiling fans on to circulate the air.
Lani and house are very comfortable found no need for additional conditioning
The only thing we did do was add solar shades to block the sun and add privacy

A neighbor purchased one of these units and it also has a heat cycle to take the chill out of the room during the winter months. Got to say that this unit works very well with cooling and heating the lanai. They have a Foxglove CYV with the standard lanai.

Basically, this is not a good idea. You are effectively trying to negate the laws of physics in the sense that the house AC is not really designed to handle the additional load. It won't cool it that effectively plus will put more stress on your AC over time. It's like driving your car with an extra 1000 lbs in the trunk. You can do it but at some point you pay the price.

The right way to do it is a) insulate your ceiling and b) install a Mini-split.
