I always took my home's heating and cooling system for granted. That is until I found myself battling one of the hottest days in years and my air conditioner simply refused to turn on. After contacting my local HVAC contractor, I learned that my cooling coils had frozen over from a lack of maintenance. He did get my AC back up and running that day, but he also helped me to look at my heating and cooling system in a whole new light. I have spent a lot of time over the last few years learning more about how to properly maintain my HVAC system and ultimately lower my energy costs. Today, I would like to share this knowledge with you so that I can help you to avoid some of the costly mistakes I have made in the past.
If you recently decided to install a ductless air conditioning system, you have made a good choice in an efficient means of cooling your home. However, like all residential cooling systems, you can expect that at some point, your system will have a problem and need residential AC repair. Going forward, you should know what to expect in terms of repairs for this type of system.
The Heat Pump May Go
A ductless system relies on a heat pump. The heat pump is the main part of the system that hangs out outside of the house. It is exposed to all weather, and therefore more likely to wear out. Heat pumps are very efficient for warmer climes but do not always fare well where temperatures turn cooler in fall and very cold in winter. The only exception is a heat pump that doubles as both a heating source and a cooling appliance, and that generally does not work that way with ductless systems. If the heat pump wears out, there is only one option for it. You have to replace it.
A Wall Unit Could Drop Or Be Knocked Off The Wall
Wall units are essentially the air collectors that are mounted to walls in a room. They are lightweight and connected to a hose and a few cables and that travel to electricity sources and the heat pump outside. If it drops off the wall or gets knocked off the wall (which would require some force!), it could break, or it could pull cables and the hose out of the wall and create some damage. If that happens, the HVAC repair technician has to repair and/or replace the damaged parts and get a new wall unit mounted more securely to the wall.
The Air Collection Hoses Could Split Or Be Chewed
The air collection hoses that travel from the wall units to the heat pump outside are very thick and very sturdy. However, they are not indestructible. They may split over time, or if you end up with a rodent problem, the rodents might chew on the hoses in the walls. If that happens, your hot air will collect inside the walls and the house will not feel any cooler. The first issue is to get rid of whatever caused the problem, whether that be pest control or the removal and replacement of a split hose, and then the AC will work properly.Share
