Heat pumps and hot water heaters?

If you are getting ready to sell your home think about the heat pump and hot water heater. They are definitely not eye candy but systems in poor condition will likely cause you concerns during negotiations. I recommend having the heat pump system serviced by a HVAC technician before listing and document so you can show the buyer. If it beyond servicing consider putting in a new, energy efficient system. It will help the selling process to go much more smoothly.
My only comment on hot water heaters is if they are old and corroded they should be replaced. Any competent home inspector will note a corroded hot water heater in their report. A nice new hot water will be much more appealing to buyers.
These recommendations will make the selling process go much more smoothly and possibly but money in your pocket.
