Today, we got an emergency call from a homeowner saying, “I think my heat pump waterlogged!” It’s unlikely due the the small amount of rain we actually get here in our area of AZ. But, it is also possible that she may be right. It happens from time to time. Especially after a bad storm moves in, and EVERYTHING gets flooded.

For most, there are no worries…HVAC systems don’t need much time to “dry out.” Heat pumps and other outdoor HVAC systems are designed to withstand the elements of weather—all kinds of weather–and that includes a lot of rain. But, what happens if excessive rains caused flooding? How does a homeowner know that the A/C is going to work properly after? Flooding has it’s own problems…

Of course, the first thing to do is to make sure it is safe at the home after the flood. It probably is the best idea to call out an Alaskan Air Conditioning technician to your house. Depending on how severe the flooding was, some or several of your electrical circuits may not be functioning properly. Breakers may be tripping and as we all know water and electricity don’t mix. Again, it’s better to be safe than sorry so have it checked out by one of our technicians.

If the unit was submerged for any length of time, you may need to replace all the wire in the system and if there are any control boards in the unit, you may have to replace those.  Water soaks into the wire. Water could cause the board to go bad and short circuit. Over the long term, depending on the mineral content of the water, the wire will corrode, If the condenser was flooded, in a heat pump or conventional air conditioning system, it definitely needs to be replaced. It may just be best to get an entire new heat pump system, especially if it is already 10 years or older.

For a professional diagnosis of your heat pump system that has been flooded, do the safe thing and call an Alaskan Air Conditioning technician.
