FAQ

• What is meant by a 'ton' of refrigeration?

  Confusingly, the unit has little to do with weight, as used in everyday language. One ton of refrigeration is the term used to refer to 12,000 B.T.U.s/hour (British Thermal Units/Hour) of cooling effect. Thus, a condensing unit with a cooling capacity of 60,000 B.T.U.s/hour is said to have a capacity of 5 tons.
  

• What maintenance should I do on my air conditioner?

  The most important maintenance you can do is to change your filters regularly. Ground mounted outdoor units need to be kept clear of debris, clutter; weeds or landscaping that can grow too close and reduce the airflow to the unit. Also, keep pets away from the unit because pet urine can cause expensive damage. Use caution with a weed trimmer around the unit to prevent damaging control wiring. Any additional maintenance should only be performed by qualified personnel.
  

• Is HVAC with more capacity better?

  No. Larger system is more expensive to operate, and it delivers less comfort. A system is the least efficient when first turning on. HVAC with too much capacity will continuously turn on and off, proving to be less efficient than the HVAC of the right size for your space. It is important to remember that an air conditioner dehumidifies air only when it is on, thus the HVAC with more capacity will not perform the job very well.
  Should I close the registers and doors to areas I am not using?
  Every system is made to cool a defined number of square feet. If you close the registers and/or doors to certain rooms that you do not use, you disrupt the airflow, and your system will work harder to circulate air to those areas. It will use more energy to cool less space, making it less efficient.
  
  

• Why are humidifiers used in heating more often than cooling?

  When outdoor air enters a home and gets warmed up, it dries out, which increases static electricity and can even lead to sinus problems. A humidifier helps add moisture back into the air, helping to minimize the chances of sinus problems. The average comfort level for humidity is 35-45%.
