AC Repair | Central Air Conditioning Units: 7 Easy Maintenance Tips Pt. 2

AC Repair |  2. Wash pollen and other debris off condenser unit

If your outdoor air condenser unit is in an unnoticeable location, it’s very easy to forget about cleaning it regularly. But you don’t want to neglect this very easy chore. The condenser pulls in air, and when it does, pollen and other debris often cling to its exterior. This will restrict airflow and cause a decrease in cooling efficiency and perhaps even cause the unit to overheat.

The solution…

Pull out your garden hose and with a hard stream of water, working top to bottom, hose off each side of the condenser.

3. Do not close any registers completely

With a two-story house the upper level is often warmer than the lower level even with the central air running. This is the case with our home, and knowing that hot air rises and cool air falls I figured I could easily balance the air temperature by adjusting the register (air vent) openings.

The mistake:

It is true that closing some registers on the cooler lower level forces more air out of the registers upstairs. The cooler air then works its way downstairs and the air temperature becomes more even throughout the house. However, by doing this the air conditioning unit may completely shut off!

In fact, when I totally closed some lower level registers, the coils in the unit froze and the A/C quit functioning. Luckily, by shutting off the entire cooling system and giving the coils time to thaw, the A/C was up and running again within a few hours.

The lesson:

Do not completely close registers. To balance the air temperature, registers can be slightly closed, but do not close them completely. (It took me two times to learn this lesson.) Additionally, make sure supply vents are not blocked.

4. Change the filter regularly

Maintaining a central air conditioning unit is all about maintaining airflow. That is why it is important to regularly change the air filter on the system. Filter packages usually state a recommended schedule for replacement (i.e. every 90 days or so) but it really depends more on how much the unit is running and how dirty the air is. During hot months it may be beneficial to change the air filter more frequently. The process is often as simple as sliding the old filter out and sliding in the new one.

 

5. Set temperatures in a programmable thermostat

It stands to reason that the less the air conditioner is actually in use, the less wear and tear it endures. For anyone with a programmable thermostat, setting the temperature by day and time is a good way to reduce the unit’s overall usage.

For example, we set our temperature higher during the daytime and colder during the hours when we sleep. It’s far more efficient to program in desired temperatures than it is to shut the unit off completely and then turn it on after a day of work.

6. Keep the sun out

Another excellent way to keep the air conditioner from needing to run as often is to block the sun during the hottest part of the day. During the hours when the sun shines in the most, blinds or drapes should be closed. This way the home’s interior temperature will not rise as much. Additionally, consider planting trees or installing awnings to diffuse some of the sunlight.

7. Get a professional inspection and cleaning done annually

Before each cooling season it is a great idea to get a regular maintenance check and cleaning done on the unit by an HVAC professional. Service professionals usually inspect the control box; coils; fan motor and blades; and compressor and tubing; among other things. Additionally, refrigerant levels are inspected and adjusted if necessary, and the unit cleaned.

As the old saying goes, an ounce of prevention is worth a pound of cure. If you’ve ever had your central air conditioner quit working on the hottest day of the year, you fully understand that preventative A/C maintenance is definitely preferable to repairing or replacing it due to neglect. -Hub pages
