 Energy Saving Tips

  1. Install and set a digital thermostat, it could help you save up to 10 percent on heating and cooling costs per year.

  2. Use a fan. Ceiling fans will allow you to raise the thermostat setting about 4 degrees without impacting your comfort.

  3. Insulate your attic and walls, and seal cracks and openings to prevent warm air from leaking into your home.

  4. Insulate and seal ducts. Aair loss through ducts accounts for about 30 percent of a cooling system's energy consumption.

  5. Don't heat your home with appliances. On hot days, consider using an outdoor grill instead of your oven.

  6. Install energy-efficient window coverings that let natural light in and prevent solar heat gain.

  7. Buy an ENERGY STAR-qualified A/C unit. On average, they're up to 15 percent more efficient than standard models.

  8. Use the bathroom fan when taking a shower or bath and a range hood when cooking. This helps remove heat and humidity from your home.

  9. Inspect your A/C Filter monthly and replace when needed. An easy way to remember to do this, is every time your electric bill arrives. Dirty filters cost money in poor efficiency, and also cause unnecessary extra wear on the system.

Common A/C Problems

Your Air Conditioner has a hard time keeping your house cool:
Possible Cause: Explanation:
Refrigerant Your refrigerant could be low or leaking. Our trained technicians can repair the leak and recharge the system.
Check your thermostat to make sure it is set properly and it is reading the correct temperature.
Check your unit's drain to make sure it isn't clogged.
A clogged filter restricts airflow through the unit, decreasing its efficiency and reducing its ability to effectively cool the air.

Your A/C isn't turning on:
Possible Cause: Explanation:
A breaker is by design to prevent an overload to a circuit. Although a breaker that continues to throw itself off could be simply a faulty breaker, it is best to call Castle Air in this case as something in the A/C unit may be over heating and will cause additional further damage if left untreated.
Electric Control
Your compressor and fan controls could be worn out from having your system turn off and on too frequently. Call Castle Air and our trained technicians will check your unit's electrical connections.
Thermostat Make sure your thermostat is working -- it might need new batteries or might need to be replaced entirely.

A clogged filter restricts airflow through the unit, decreasing the efficiency and reducing the ability to effectively cool the air.

Water from my A/C is leaking into my house: The warm air that is removed from your house blows over the evaporator coils. This causes condensation, similar to water droplets that form on a glass of cold water on a hot day. Your A/C system returns this water outside through a drain, but sometimes problems develop and it leaks into the house.
Possible Cause: Remedy:
Clogged condensation
