Frequently Asked Questions

What does a humidistat do?
A humidistat is a very useful device that helps you keep your home dry and mold free.A humidistat detects the amount of moisture in the air and automaticallt turns on your air conditioner when the moisture in the air gets too high.

A humidistat can lower your utility bill becasue your air conditioning unit comes on only when the humidity is higher than desired.While useful all your round, a humidistat is espcially important when you are away from home for any length of time.

How often should I change my air filters?
For best performance of your system your air filters should be changed every three months but this can depend on the conditions in your home. If you typically have to dust your furniture once a week then you should stick to the quarterly filter changes. You can tell when to change an air filter by inspecting the back side of the filter, any discoloration on the back side (dirt) indicates the filter is fully loaded and is releasing dirt into the air stream.

What does SEER stand for?
SEER is an acronym for Seasonal Energy Efficiency Ratio. The SEER rating of a unit is the cooling output in BTU's (Britich Thermal Units) during a typical season divided by the total electric energy used in watt-hours during the same period. The higher the unit's SEER rating the more energy efficient it is.

How much money will a high efficiency air conditioner save me?
This depends on the age of your system, how you use your system, and the temperatures you set on your thermostat. Efficiencies have increased dramatically over the years. Air Conditioners ten to fifteen years old or older typically have an efficiency rating of 7 to 10 measured in SEER. While today you can purchase air conditioning equipment with ratings as high as 18 or 19 SEER.

What does a thermostat do?
A thermostat is a device that is used to control a heating or cooling system so that it maintains a certain temperature or keeps the temperature within a certain range. In a home, for example, this device can automatically turn on the heating system when the temperature in the home drops or turn on the air conditioning when it gets too hot. As the warm or cool air fills the room and the desired temperature is achieved, the device then turns off the system. There are two main types of thermostats: mechanical and digital. Many digital thermostats also are programmable, which allows a user to set different preferred temperatures for different times of the day or days of the week.

Will a programmable thermostat really save me money?
Generally, as with anything, this depends on how it is used. A rule of thumb is the more you set the thermostat to adjust the temperature above or below your standard setting the more you save. Adjusting the temperature just a couple of degrees while your sleeping will save you money alone but if your home is unoccupied during the day then the savings can be substantial. You can expect a basic programmable thermostat to pay for itself within the first year under the best circumstances and easily within two to three years in circumstances where the adjustments are minimal.   

How does a maintenance service save me money?
Many times during a regular maintenance service an inexpensive part such as a motor capacitor is found to be faulty, when this type of failure is unknown it will lead to failure of much more expensive parts such as the motor itself. This alone will save you hundreds of dollars in repairs. Many compressor failures on air conditioners could also have been prevented by catching simple inexpensive items such as the capacitor for the condenser fan, again just liked mentioned above except in this case the failure of the condenser fan motor leads to the failure of the compressor. Keeping the system clean and operating at peak efficiency will not only obviously save you energy but will also prevent failure of expensive parts like the blower motor and compressor.
