Two Common Summer Repair Calls
This week, since we will likely see our first 90 degree day in Richmond, we’ll take a look at two of the most common air conditioning repair calls we get in the summer and how you can take a few steps to take care of these problems before you need to call an AC repair technician out to your home. The issues we’ll be looking at are clogged drain lines and a frozen indoor ac coils.
Some signs that you may have a clogged drain line:
- No condensation is running outside from your condensate drain line that comes off the indoor ac unit.
- Your digital thermostat display is blank.
- Water is leaking from your indoor ac unit.
- There is a visible blockage in the condensate drain line trap.
If there is a visible blockage in the drain line trap you may be able to clear it up with a long brush. Another method is to pour bleach into the drain line to try to dissolve the clog. Consider having an EZ-Trap installed if you have problems with drain line clogs. This type of trap makes it easy to spot and clear blockages. We can install a Safety switch on your system to prevent damage to ceilings and floors.
A frozen indoor coil is more difficult to notice, but can easily be prevented by changing your filters routinely and having regular maintenance by your HVAC company. When a filter gets very dirty it will cut down on the amount of airflow through the indoor unit and cause the indoor coil to freeze up.
Symptoms of a frozen indoor coil include:
- Very little airflow from your vents.
- Excessive condensate drainage.
The easiest way to thaw a coil is to turn the system off and let it melt by itself. This can take some time, depending on how long the system has been frozen. If your system is frozen, but your air filter is not excessively dirty, this may be an indicator of other problems in your system which will require a diagnosis from your heating and cooling company.
