FAQ

• What size is my filter and how often should I replace?

  There's no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate. Start by checking the system's filters at least once a month. Hold the used filter up to the light and compare it to a clean "spare". When light is obscured by captured dust and dirt particles, the old filter should be changed. Keep a record for one year and then replace the filter on that basis. At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. Also, it is a good idea to have your heating and air system checked at the beginning of heating and cooling season to insure proper operation.
  

• 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%.
  

• 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.
  
  

• How can I do to make my HVAC more efficient?

  Replace and clean your filters often in order to boost the efficiency of your HVAC. Make sure the blower is ON – it ensures the constant air movement, helping the system cool or heat more evenly. Windows facing the south, or those exposed to direct sunlight most of the time, should be equipped with window treatments (drapes, shutters, blinds, screens).
