Considering the hot climate we experience here in San Antonio, with summer days often exceeding temperatures of 100 degrees, you need your AC system to operate at optimum levels at all times. If you haven’t had anyone look at your air conditioning yet this year, it’s not too late. There are hot days ahead. Preventive maintenance checks can ensure that your AC system works well on an ongoing basis and also extends its life.
The Air-Conditioning, Heating and Refrigeration Institute (AHRI) provides the following tips on how to keep your central air conditioning system running efficiently:
- Check the air filter to be sure it is clean. If it is dirty, either change it or wash it (if it’s the reusable type). Air filters should be cleaned or changed on a monthly basis.
- Clear away debris, such as leaves, weeds, mulch, grass, plants and hoses that block the airflow through the outdoor condensing unit.
- Periodically clean the outdoor condensing unit by spraying it with a water hose.
- Check to be sure that your home’s air conditioning vents are not blocked by furniture or other large objects.
- Close off rooms that are not being used and close the air conditioning vents in those rooms. You should consider adding zone controls in the seldom-used areas, which will substantially reduce cooling costs.
- Fan speed should be placed on high.
You should also have a trained, certified HVAC technician perform a preventive maintenance check on your air conditioning system. The contractor will check:
- Refrigerant level and possibility of leaks
- Electrical connections — Tighten and clean
- Thermostat settings and accuracy
- Condensate drain — Make sure it’s not clogged
- Duct work — Seal any leakage
- Belts and oil motors — Tighten; check for wear and tear
- Evaporator coil airflow
- Electrical control sequencing
- Blower components
