I am a home owner. I want the Owner's Manual, not the installation Manual. Where do I get it?

Our "Installation and Owner's Manuals" are written for both the contractor and the home owner. Keep yours handy for proper maintenance and repair reference for the life of your unit. If you no longer have yours, you can download the applicable manual here

I want to install one of your units in my place of business. Is that alright?

While our products are manufactured for whole house residential applications, commercial installation is acceptable. Please carefully review product specifications prior to installation to ensure the model adequately accommodates your space.

EXCEPTION:  Installation of our steam humidifiers in commercial settings is not recommended.  To install a steam humidifier in a commercial setting voids their warranty.

What do I do if I suspect that combustion appliances are affecting my health?

If you suspect you are being subjected to carbon monoxide poisoning get fresh air IMMEDIATELY. Open windows and doors for more ventilation, turn off any combustion appliances, and leave the house. You could lose consciousness and die from carbon monoxide poisoning if you do nothing. It is also important to contact a doctor IMMEDIATELY for a proper diagnosis. Remember to tell your doctor that you suspect carbon monoxide poisoning is causing your problems. Prompt medical attention is important.

Remember that some symptoms from combustion pollutants - headaches, dizziness, sleepiness, coughing, and watery eyes - may also occur because of common medical problems. These medical problems include colds, the flu or allergies. Similar symptoms may also occur because of other indoor air pollutants. Contact your doctor for a proper diagnosis.

To help your doctor make the correct diagnosis, try to have answers to the following questions:

  • Do your symptoms occur only in the home? Do they disappear or decrease when you leave home, and reappear when you return?
  • Is anyone else in your household complaining of similar symptoms, such as headaches, dizziness, or sleepiness? Are they complaining of nausea, watery eyes, coughing, or nose and throat irritation?
  • Do you always have symptoms?
  • Are your symptoms getting worse?
  • Do you often catch colds or get the flu?
  • Are you using any combustion appliances in your home?
  • Has anyone inspected your appliances lately? Are you certain they are working properly?

Your doctor may take a blood sample to measure the level of carbon monoxide in your blood if he or she suspects carbon monoxide poisoning. This sample will help determine whether carbon monoxide is affecting your health.

Contact qualified appliance service people to have your appliances inspected and adjusted if needed. You should be able to find a qualified person by asking your appliance distributor or your fuel supplier. In some areas, the local fuel company may be able to inspect and adjust the appliance.

Why is it so important that I hire a NATE certified, licensed contractor?

A contractor cannot obtain a license without possessing a minimum amount of training / experience / knowledge / skill; therefore they are more qualified to do the job. Because they are more likely to do the job correctly the first time, you'll experience fewer callbacks and less frustration. Most often people that take the time to get certified are more likely to enjoy their job and are more likely to stay with it a long time. The applicant also may be subjected to a criminal history background check, and must not have any unresolved contracting complaints outstanding.

Should you experience problems with licensed contractor, a residential property owner has significant protections not available to persons utilizing an unlicensed contractor. Among them is the ability to file a complaint against the contractor's license, in most cases, for a period of two years from the date of occupancy or date the last work was performed (check local laws). This is your guarantee should the workmanship be below standard or in violation of existing codes.

A NATE certification is not required to be a licensed contractor; however, a NATE certified contractor has gone through some of the most rigorous training in the field. NATE certification tests represent real world working knowledge of HVACR systems. All of the NATE tests are rigorous, multiple-choice, knowledge-based tests and validate a technician’s knowledge.

How can I be sure a contractor is licensed?

  1. Ask him / her to provide written proof of licensing and insurance.
  2. Confirm with the company; ask if they do background checks and drug screenings of their employees.
  3. Ask them for online references, such as facebook, Angie's List or Google Places. (Anyone can give you a list of people who like them. The online sources are not as easily controlled by the contractor and represent a more solid investment in his / her / the businesses' future.)
  4. Ask for their product, parts and labor warranty information.  (Do they back their work?)

Additionally, to ensure satisfaction of the work you hire this person to do, you may also ask:

  1. What is your experience? (How many years have you been doing this?)
  2. Does your organization, or do you, carry a Surety Bond? (If the contractor fails to meet conditions of the bond, the consumer may file a claim against the bond.)  Simple liability insurance does not necessarily protect the home owner.
  3. Do you carry any special certifications?  (Certifications represent someone who has sought further education above and beyond meeting the minimum requirements to get a license!)
  4. Will you provide a written estimate of the work?

Why should I install a Whole House system Vs. a portable / one-room unit?

Portable units can be very effective in treating a room in which they are placed, but they treat the air in their immediate vicinity only.  Unfortunately, you travel to other contaminated rooms throughout your home.  When you re-enter the treated room, you re-infect the room with the same contaminants you are trying to remove.  You would have to purchase a portable unit for every room of your home to ensure the whole house is treated.

Portable units can take up ample space in a room (felt most by those living in tight quarters) and aren't always very attractive. Additionally, one-room, portable units require more maintenance and can be quite noisy.

Whole House systems are easily installed in you HVAC system; are quiet, out of site and require little maintenance. Additionally, the whole house is protected 24-7; 365 days per year. 

Where can I find brochures for my humidifier and air cleaner?

Literature for a particular product can also be found on each product (humidifier, dehumidifier, air cleaner, UV Air Purifier, heat / energy recovery ventilator) page throughout our site.  In addition product catalogues / guides for GeneralAire® and General Filters, Inc. products can be found here.

Your order will be shipped USPS-Priority Mail. We've found this to be the best value to you and provides additional benefits:

  • USPS-Priority Mail is as reliable and fast as other carriers.
  • USPS-Priority Mail reaches over 90% of the United States within 2-3 days.
  • For packages sent in one of the USPS standard-sized boxes/packages, you are not penalized for being located further away from our offices (than a closer zip code). USPS ships their standard-sized packages at a flat rate throughout the USA.
  • USPS-Priority ships on Saturdays at no extra cost.
  • There may be a rare occasion we would ship via a different carrier when we find it benefits YOU.

CALL YOUR ORDER IN, TOLL FREE:  (866) 476-5101 in the following circumstances:

  • To request a different carrier other than USPS Priority.
  • If you need overnight delivery.

I used your "Find a Local Contractor" tool, but when I searched using my zip code, no contractors were listed. Why?

If you perform a search but the words "Sorry, there were no results that matched your search" was returned, it simply means we have yet to hear from contractors in your area that want to be listed with our site. They might not even know it exists.

If you hire a contractor with which you are pleased, please ask him / her to fill out the Contractor List Request Form to be included with our "Find a Local Contractor" search tool.

Your recommendation is one of the best ways we can be sure qualified, honest GeneralAire® contractors are included!
