Just performed a Routine Maintenance and Tune Up on a 10 year old Luxaire Heat Pump in Wilmington Delaware. Found a couple of issues and are working with the owner to find the best solution for them to handle it! As of now everything is working great, just found some potential issues that will eventually be a real problem. Staying ahead of the problems as they come makes everything way easier and way cheaper. Sometimes the issue is to just let it run its course of natural selection.
