3 AC Problems for AC Repair 77038

As the cooling season approaches in earnest, this is a great time to give your air conditioning system some preventative care to ensure it runs smoothly for the warm months to come. In South Texas, we increasingly depend on the AC for our health and comfort. While we can do without AC why would you if it was not necessary? Here are the top three AC problems to look for with your air conditioning system.

1 Delayed Maintenance

This is still the #1 cause of air conditioning problems, even though homeowners get plenty of reminders.

• The simple task of changing the air filter regularly helps an AC system function properly and efficiently. Change the filter at least every three months—more if your locale has excessive airborne contaminants.
• Air conditioning function requires metal coils to be exposed to large amounts of moving air; this must happen twice. The first location is the outdoor condenser unit. A central fan pulls air through a network of coiled tubing and very thin fins to quickly dissipate heat. Leaves, grass, dirt, and pollen fill in the gaps between the coils unless it is washed away. A garden hose is sufficient; do not use a power washer since this can damage the fins.
• The evaporator coils are located inside the central air cabinet. Flip the breaker for the AC and remove the cover to expose the A-shaped network of tubes. This coil stays wet, and when dust encounters the wet surface, it sticks. No worries. Fill a spray bottle with a 50/50 mixture of vinegar and water to wash it all away. Be sure to clean the drain pan below to prevent buildup or debris from clogging the drain line.

2 Leaking Refrigerant

Air conditioners use a refrigerant that works just like antifreeze in a vehicle; it collects heat and moves it to the outdoor environment. The product in air conditioners is commonly called Freon, but it refers to several product formulas.

• The compression and release of Freon accounts for the movement of heat, and it ALWAYS responds the same way under the design pressures. Under pressure, Freon turns to a gas. When it is released, it reverts to a liquid.
• When even a little Freon leaks away, the gas chemistry changes. Cold things now freeze the surrounding humidity. When more leaks away, air conditioning functions stop altogether.
• Refrigerant gases can be quite expensive. Remember, recharging the Freon pressure without fixing the leak will result in the new Freon leaking away as well.

3 Aging Electronics

The components that move the refrigerant and the air necessary for air conditioning function are a series of switches, sensors, and motors. These parts experience micro-violence every time a cooling cycle begins, so they do wear out.

• The thermostat on the wall is the ON/OFF switch for the HVAC system, powered by AA or AA batteries, which will need to be changed annually.
• The electrical controls work in series—one switch triggers other switches and sensors. For this reason, when one control weakens or fails, it affects other controls and switches. This system needs to be checked annually so that weakened controls do not stress the rest of the system.
• A blower motor moves a massive amount of air during each cooling cycle: the entire volume of the space recirculates about every two minutes. This powerful motor needs to be cleaned and maintained.

The best step for preventing these three problems is to schedule preventative maintenance annually.
