The ABCs of A/C Maintenance

Posted by Paul Wadsworth on Wed, Sep 01, 2010 @ 09:09 AM

It may seem like school is just around the corner and summer is slipping away, but your A/C unit still has quite a few weeks left of hot and steamy weather to combat. By reviewing the ABCs of A/C maintenance, you can help ensure your unit makes the grade for the rest of the season.

Here is a handy air conditioner maintenance checklist recommended by the Environmental Protection Agency (EPA).

[  ] If your unit has been running continuously for a while, turn it off and let it sit for a minute. Then turn it on again. If it starts, it has passed the first test.

[  ] Check the settings on your thermostat. Now that it’s been running for a couple of months, why not see if you can set the times so that it feels even better in your home. More importantly, make sure that the unit turns on and off at the appropriate times.

[  ] See if all the electrical connections fit tightly. You can even test your A/C motor’s current and voltage, if you have the proper tools. Most of the time this is best done by a qualified technician unless you have a lot of experience and the proper tools and safety equipment.

[  ] Unclog the drain if necessary. Sometimes debris can collect on the cooling coil located above the furnace.  There is a drain from this unit and it can become clogged.  Again this is project that may be left to a qualified technician to make sure the problem is magnified by pushing the debris the wrong direction.

[  ] Check your coils. Again, yard clippings, dust, and pollen can clog your unit’s coils. Clean them out with a commercial coil cleanser that is rated not to deteriorate the coil material and a garden hose set on shower or fan. Performing this necessary and basic A/C maintenance task will increase the both the efficiency and life of your A/C unit.  Make sure that you are sure that all electrical power is off at the main panel inside the home or building and verify this with an appropriate electrical meter.

[  ] Change or clean your filter every month or at the interval suggested by the manufacturer

[  ] Check the pressure of the refrigerant. Again this is almost always the job of a qualified technician.  Even with the proper gauges, tools, and specifications, this can get tricky. But if you notice that your air conditioning unit isn’t cooling as much as it used to, and it’s been properly cleaned, you may need to have a technician check/recharge your unit.

[  ] Check the airflow and clean the blower if it needs it.  Make sure there are no obstructions to air conditioning outlets or inlets.  Also make sure that no adjustments dampers have gotten loose.  A cleam filter is also important here.  Some of the internal components can become clooged and this will likely take a qualified technician to evaluate most of the time.

These are just  basic measures any homeowner can take- often with the assistance of a qualified technician.  . However, if you follow a good routine of A/C maintenance, you can keep your unit running cooler—or warmer, winter is coming—for years to come.  Of course, having us come out regularly to maintain your air conditioning equipment will give you extra peace of mind that your A/C won’t let you down when you need it.
