English to Spanish Marketing Energy / Power Generation survey about energy usage

As in "which of the following types of air conditioning systems, if any, do you have in your home"? (followed by multiple choice responses including "central air", "room air conditioners", "evaporative coolers" etc.)

Please help me figure out how the "if any" would be written within the context of the entire question (where it would be placed, etc.).

So far I have " ¿Con cuáles de los siguientes sistemas de aire acondicionado, si los hay, cuenta su hogar? "

Is that correct, incorrect, could be better? Any suggestion is welcome, but I'm most interested in finding out which is the most common way this is translated, particularly in market research surveys.
