Air Conditioning Frequently Asked Questions and Tips

  • Check your thermostat settings and make sure it is set below room temperature and that it’s on the COOL or AUTO position.
  • The fan switch should be set to ON for continuous airflow. AUTO will make the blower run only when the air conditioning system is operating.
  • Try to get the system to turn on by lowering the thermostat to the lowest temperature setting.
  • If there is low air flow from your registers, the air filter may need to be replaced.
  • Check all registers to make sure they are open and unblocked.
  • Check the power disconnect switch by your indoor and outdoor units.
  • Make sure your electrical panel breaker box isn’t blown for your indoor and outdoor units.
Seasonal Energy Efficiency Ratio measures the efficiency of your air conditioning unit on a scale between 10 and 20 SEER. Since 2006, the federal government requires residential A/C systems to have a minimum of 13 SEER. The higher the rating, the more money you save on energy bills!
Summer days with a high level of humidity feel about 20 degrees warmer than the real temperature. Using a dehumidifier will absorb the humidity inside your home and make it feel cooler than what your thermostat reads. A/C systems naturally have a built-in function to dehumidify, but it’s always a good idea to pair the two units together to maintain the best quality of cool and dry air. This is especially necessary if one room of your house has a high level of humidity, like the basement or laundry room.

It’s important to maintain an even amount of humidity for anyone with allergies. Too much humidity can cause bacteria, dust, and mildew to grow—common triggers for an allergic reaction. A dehumidifier is key to cutting costs on energy bills—while saving the earth at the same time!

When fall arrives, winter is only a couple months away. It’s a nice little reminder to prepare your A/C unit for the frigid cold months ahead. This will extend the life of your unit and ensure it works properly for the next season.

First, flip the switch to your electrical circuit located next to your air conditioning unit. Next, remove any leaves, debris, or sticks next to your system. Wrap foam covers around the exterior pipes leading to your air conditioner to insulate them and prevent the pipes from freezing. Finally, cover the system with plastic or vinyl that is waterproof and secure it with a bungee cord. Check your unit periodically during the winter months to remove snow from the top of your unit and make sure it is still covered properly.

This is a myth. Your house needs the appropriate-sized air conditioning unit that is recommended for the square footage of your home. This will ensure it runs at peak efficiency. If your air conditioner was installed by Sabre, you can rest assured that your unit is the proper size.

Another reason you don’t want an oversized unit is it takes a lot of energy for your unit to start up and shut off. If it is consistently powering up and down throughout the day, then you’re shortening the life of your air conditioner. This will also cause some costly repairs down the road and your energy bills will be high.

Your air conditioner should definitely be cold to the touch, but not so cold that ice appears! Call Sabre as soon as you notice ice. Turn off the unit so that it can defrost. To avoid the formation of ice, replace your air filter at the recommended intervals. Insufficient ductwork, a dirty unit, a broken blower, or a small amount of leaking refrigerant could be other causes.
