Air Conditioning Tips & Advice

Air Conditioning Tips & Advice (4)

One of the best ways to reduce your cooling bill during the summer months is to reduce the sources of heat and humidity inside the home that can make your air conditioner work harder to cool your home. Here are some of the most common sources of heat and humidity inside the home.

1. Lighting - Older incandescent light bulbs lose as much as 90% of their energy as heat loss. By upgrading to more energy efficient CFL or LED bulbs, you won't just reduce the heat, you'll save electricity as well.

2. Kitchen - Kitchens are a major source of heat and humidity inside the home. When the weather is hot, consider cooking outside on a grill, or use a microwave instead of your oven or range. 

3. Laundry Room - Clothes dryers generate a lot of heat and humidity. Consider hanging clothes outside on a clothes line. An exhaust fan installed in the laundry room will help to vent the hot, humid air outside.

4. Dishwashers - During hot weather washing dishes in the sink will reduce heat and humidity. If you run the dishwasher turn off the heat dry and let the dishes air dry instead.

New air conditioners built within the past few years are designed to operate so quietly you will hardly know they are running. So when you hear unusual noises, it is usually the result of a lack of maintenance or a symptom of a part that is about to fail. By staying alert to the sounds of a malfunctioning air conditioner you can fix the small problems before they lead to a major failure.

When your air conditioner is working normally it will often make some noises. Subtle thumping and whining sounds are normal. By becoming familiar with the normal operating sounds that an air conditioner makes, you will be able to more easily recognize unusual sounds that could be cause for concern.

The Sounds of a Malfunctioning Air Conditioner

Air conditioners have many parts; there are fans, hoses, belts, compressor motors, coils and other components that work together to move cool air throughout your home. As air conditioners age belt often become loose, leading to thumping sounds. A clogged air filter reduces air flow and can cause the unit to whine as it cycles on or off. Loose hardware on compressor parts can lead to rattling sounds.

Preventative maintenance is the best way to minimize the likelihood of air conditioner repairs. An AC tune-up includes the following steps that keep your air conditioner operating quietly and reliably:
  • Inspection and lubrication of all moving parts
  • Inspection and replacement of worn belts and hoses
  • Replacement of dirty air filters
  • Ensuring that the unit cycles on and off properly
  • Inspection of electrical connections
  • Inspection of refrigerant levels

If your noticing ice around your air conditioner's condenser coil, or the unit has stopped operating because of freezing, there are a few possible causes. 

1. Lack of air flow. An air conditioner works by taking the heat from inside the home and blowing it over the evaporator coil located outside the home. This split-system enables the heat exchange performed by the refrigerant to take place. Without the exchange of warm air the temperature of the coil will continue dropping, increasing the likelihood of a freeze up.

2. Low refrigerant levels. As the level of refrigerant drops, so does the pressure inside the system. When a smaller amount of refrigerant is forced to expand the same amount, it lowers the temperature.

3. Low outside temperature. If an air conditioner is run when the outside air is too cool, the pressure inside the unit can drop, causing a freeze up. This can occur at temperatures of around 62 degrees.

4. Malfunctioning mechanical systems. A damaged refrigerant line, broken fan, even a clogged up air filter, can cause the evaporator coil to freeze up.

Help! My Air Conditioner Won't Turn On

Written by
It's the first hot day of the season and you go to turn on your air conditioner... and nothing happens. Before calling Maitz for service there are a few things you can check yourself.
  • First, check that the thermostat is set to "Cool" and not been unintentionally switched to the "Off" or "Heat" setting.
  • Turn the thermostat temperature down a few additional degrees to see if it turns on. 
  • Check that the external safety switch is set to the on position. The switch will be located on an exterior wall near the AC condensing unit.
  • Check that the circuit breaker that controls the air conditioner compressor and air handler are set to the “on” position. If a circuit breaker has tripped, reset the circuit breaker. If the circuit breaker trips again, do not try to reset it. Have Maitz check the unit to determine the cause of the problem.
If your air conditioner still won't turn on, call Maitz Home Services, we have fully stocked trucks in your you neighborhood with technicians who can quickly diagnose the problem and getting your air conditioner running again.
