Sometimes you know that the old system wont make it to next season. Doing a changeout in the “off” season allows for flexibility in all aspects of changing to new system. Also, milder attic temperatures allow technicians to not rush and work continuously without worrying about overheating.

In the last several posts we have been discussing different consequences of not changing air filters or not having them at all. Some of the more severe consequences are frozen evaporator coils (inside/ air handler), which we have also discussed. When ice expands so rapidly sometimes things move and or shift. That can create small cracks in the coil which eventually leads to bigger cracks. Some systems have high and low pressure switches built into the condencers that would stop its operation if system is running outside of designed refrigerant parameters. Some do not. Those condensers tend to have burnt out compressors. At that point that is a huge expense if wether parts are under warraty or not. So again, please change your filters and make sure to do a diagnostic/ system check up at begining of each cooling season. A skilled technician (ours) can spot issues before they occur and recommend best possible solution.
Leaking evaporaor coil. Not repairable
August 3, 2017 in Uncategorized
Last week I wrote an article about having a really dirty air filter and why it is a important to change them regularly. In that article we discussed that dirty filters will restrict airflow in the air handler, which can cause serious malfunction in the system. Now, lets talk about the repercussions of removing the air filter entirely and forgetting to put one back in . The same effect as a dirty filter is recreated inside the evaporator coil. Dust gets lodged in between the coil fins, which forms into a giant patch and restricts air flow. Side effects may include coil freezing and compressor burnout. At the least it will require the coil to have specialized cleaning which may be expensive and in extreme situations the coil must be removed entirely for propper cleaning. However, this can all be avoided if the air filter is replaced regularly.

Evaporator coil dirt blockage due to lack of filter

What to do if there is a leak from attic air conditioning unit? First and foremost it is best to turn the system off at the thermostat. If possible, access the attic and confim that leak is actually coimng from ac system. There can be several reasons why the air handler (the attic unit) is leaking water.
One reason the ac can leak is a frozen system. You can see it by looking where the refrigeration line is going into the evaporator coil (the attic coil) it will have ice on it. Let the system thaw out and replace the air filter. Dirty air filter is the most common reason for a frozen system. After 24 hours of thawing, turn system on again and see if it still freezes. If it still does, there may be other underlying issues that may need to be addressed. If so, call for service (hopefully us 😀).
Other possibility could be a blockage or a break in the condensation drain line. In this situation call a professional to clear the blockage, or repair the leak.
