Heating or Furnace Questions

  • Do I need a furnace tune-up every year?

    Yes. Like an automobile, your furnace also requires regular maintenance. A furnace tune-up keeps your heater running safely and efficiently, reduces the repairs you will need and helps decrease your utility costs.

  • Why is the air so dry in my home in Winter?
    Dry Winter air can cause your humidity to drop substantially, to levels of 15 percent or less. This humidity imbalance can cause a number of potential problems that can affect your health, your home and especially your comfort. Home humidity levels should be somewhere between 30% and 50% At Custom Air, we help Central Ohio homeowners improve the quality of their home’s indoor air. A whole-home humidifier will increase your comfort and keep you warm all winter. And, because humid air feels warmer, you can actually cut your heating bill.

Air Conditoning Questions

  • Can I zone my existing air conditioning system?
    Some systems can be retroactively zoned. A Custom Air comfort advisor can provide a  FREE assessment of your system to determine your options.
  • How do I know if I should replace my air conditioner?

    If your air conditioner is more than 15 years old, it is probably reaching the end of its lifespan. We recommend replacing your AC system if:

    • Requires frequent repairs
    • It is no longer keeping you comfortable
    • Your utility bills are higher than normal

Indoor Air Quality Questions

  • What Is Indoor Air Quality?
    Indoor air quality, or IAQ, is a relatively new topic. The quality of the air you breathe air mainly has to do with the amount of pollutants inside, but it’s also determined by humidity and ventilation levels.
    • The EPA has found that concentrations of pollutants can be up to 100 times higher indoors than outdoors.
    • The American Lung Association estimates that most people spend 90% of their time indoors, so clean indoor air is very important.
    Our Indoor Air Quality (IAQ) systems can help with allergies, dust, dry skin, sinus pain, airborne bacteria, static electricity, pet dander and more! We also can repair, service, and install Humidifiers, UV lights, Air cleaners, thermostats and air scrubbers.
  • Do Residential environments always have better indoor air quality?

    According to the EPA, indoor pollution in residential buildings is caused by particles and gasses released into the air from many different sources. Volatile Organic Compounds (VOCs) found in paint, home cleaning products, and wood finishes mix with the carbon emissions from your HVAC system to cause poor indoor air quality.

    Other common sources of indoor air pollution include:

    • Tobacco products
    • Fuel-burning combustion appliances
    • Excess moisture
    • Newly installed carpet, flooring, or upholstery

    Even outdoor sources, such as pesticides or radon may cause poor indoor air quality in Columbus.

  • Can air purifiers eliminate or reduce the coronavirus (COVID-19)?

    Yes. If you choose the right air purifier, you can reduce coronavirus within your home. The iWave family of products has been tested by an independent lab to help reduce many pathogens including coronavirus. Call us at (614) 552-4822 or contact us here to learn more about the iWave.

  • Is air pollution only outdoors?

    The Environmental Protection Agency has found that concentrations of pollutants can be up to 100 times higher indoors than outdoors, so air quality isn’t just an outside problem.

    Items inside that release gas are the major cause of indoor air problems. The list includes carpeting, upholstered furniture, paints and solvents, gas appliances, cleaning products, air fresheners, dry-cleaned clothing and pesticides. If you have an attached garage, fumes from the gasoline, oil and antifreeze can make it into your home’s air. Harsh chemicals can also come from cigarette smoke and wood stoves.

    As far as allergens in your home, it’s not just your pet. Pollen particles can blow into your home through open windows, and people and pets can track them inside. Frequently damp areas also can quickly lead to mold and mildew buildup.

    Additionally, Textile fibers from clothing, curtains and other fabrics produce and collect dust. Our Indoor Air Quality (IAQ) systems can help with allergies, dust, dry skin, sinus pain, airborne bacteria, static electricity, pet dander and more! We also can repair, service, and install Humidifiers, UV lights, Air cleaners, thermostats and air scrubbers.

  • Does Indoor air quality have anything to do with allergies, asthma, or respiratory conditions?

    Yes. Indoor air quality in Columbus has a direct impact on allergies, asthma, and respiratory conditions. Allergens found in your bedroom can impact the way you sleep by causing your asthma to become worse, according to the Asthma and Allergy Foundation of America.

  • Will a good air cleaner help reduce asthma attacks?

    Yes. With the right air cleaner, you have the opportunity to improve poor indoor air quality, which could be triggering asthma attacks. If someone in your family has asthma, the right indoor air quality solution will help to eliminate pet dander, mildew, mold, dust mites, and chemical irritants, which can all trigger an attack.
