Frequently Asked Questions

What are the effects of dry air in your home?

We all have an investment in our health, our home and its furnishings. Protecting those investments from the dry air may not seem like an important task, but the effects of dry air are astounding:

  • Dry sinuses and throat
  • Increased bouts of flu, colds and other infections
  • Itchy, dry, cracked skin
  • Cracking of expensive woodwork of floors, furniture, window frames and artwork
  • Damage to musical instruments, such as an expensive piano or violin
  • Increased heating bills! As the window frames on the house crack, they let cold outdoor air in; causing you to turn up the thermostat!
  • Static electricity shocks that can damage computers, VCRs and other electronic equipment
  • Sleeping difficulties that adversely affect your mental concentration

The Solution: The GeneralAire® 1042LH Legacy Humidifier is a whole house solution to restoring your home to proper humidity levels; levels that protect your belongings, your home and more importantly, the health and comfort of you and your family. Imagine purchasing a portable unit for every room of your house. It would be expensive, noisy and would require repeated cleaning and re-filling water trays. Maintenance with the Model 1042LH whole-house humidifier is minimal: simply change the vapor pad once per year! Easily installed and tucked away in your HVAC system, it’s so quiet you’ll forget it’s there.

Stagnant water serves as a breeding ground for mold and lime, and older technology drum-style humidifiers can be harmful to your health. What can I do?

The Solution:

Bypass flow-through style:  A pipe brings water directly to an electrically-controlled valve at the top of the humidifier. Air passes through an aluminum pad which is similar to a piece of extremely coarse steel wool. The pad has a coating of a matte ceramic, resulting in an extremely large surface area within a small space. When the hygrostat calls for humidity, the valve is opened and causes a spray of water onto the pad. Hot air is passed through the pad, causing the water to evaporate and be carried into your home.

Advantages include:

  • Always fresh water and a lack of a pan of potentially stagnant water that serves as a breeding ground for mold as with a drum-style humidifier
  • Reduced maintenance (new pad required only when clogged with dust or mineral deposits, typically once per year)
  • No incidental humidification caused by a constantly-replenished pan of water in a high velocity air stream
  • Uses little electricity
  • Easy to use damper clearly marked “Summer” and “Winter”

What is AFUE?

AFUE is the abbreviation for Annual Fuel Utilization Efficiency ratio. AFUE is used to rate furnace efficiencies by dividing the ratio of heat output by heat input. This measurement describes how well gas or oil is consumed to produce heat by a furnace. As the AFUE rate increases, the efficiency of your furnace also increases, lowering your fuel costs.

What is Freon R-22?

R-22 is the common name for hydro-chlorofluorocarbon (HCFC). R-22 has been used as a refrigerant by HVAC manufacturers for over 40 years, but studies in the past decade have shown that HCFCs contain chlorine, an ozone-depleting agent. For this reason HVAC manufacturers must cease the production of products that use R-22 as of January 1, 2010.

What is R-410A?

R-410A is the common name for the hydro-fluorocarbon (HFC) that is being used as a refrigerant in the HVAC industry. R-410A is more environmentally friendly than R-22 and is the replacement for R-22 by HVAC manufacturers. At the beginning of 2010, the use of alternate refrigerant will be required in HVAC manufacturing.
