We will be starting our project soon and I think it’s possible that we will want to add a chiller in the next several years. Being in the Houston area, I want to still be able to enjoy my pool during the hottest days of summer... Is that a fairly easy retrofit? What should I do now during the build to make things easier if we decide to go that route? We are planning on an 8’ equipment pad, so we should have plenty of room.. any suggestions?
