I don’t smoke or have pets—how dirty can my air be?

Indoor air pollution is caused by many things—fumes from household cleaners and cooking, volatile organic compounds (which are emitted by paint, carpeting, and other common materials), pollen and dust that make it through disposable filters, and more. All these things can be trapped inside and accumulate over time. Even the tidiest of homes can have air that is much more polluted than outdoor air.

Doesn’t my furnace or AC filter clean the air?

Yes, to some degree, but its primary purpose is to prevent dust and other particles from getting inside the system and slowing it down. An air purifier, however, is designed to eliminate these pollutants from the air you breathe. In fact, a Carrier® system with Captures & Kills™ technology removes up to 99 percent of all airborne impurities, including mold and bacteria that can make you sick.

How important is humidity?

Air moisture levels have a big effect on comfort—too much humidity and you’ll feel hot and sticky, too little and you’ll feel cold and itchy. They can also impact your health, especially when dry winter air leads to irritated eyes, sore throats, bloody noses, body aches, and more frequent colds and flus. If that’s not enough to make you want a humidifier, know that your home wants one, too—without proper humidity, your wood floors will warp, furniture can crack, and wallpaper can peel.

What can I do about rooms that are always too hot or too cold?

The HVAC experts at Gross Heating have solutions to make every room just-right. Zoning is an option that uses motorized dampers inside your ductwork to direct treated air where it’s needed most, without wasting energy or leaving certain areas over-serviced. Ductless split systems are also a great choice if you have specific rooms that don’t have ducts or don’t receive enough heating or cooling. These small units utilize a heat pump to control temperature one room at a time.

What does the message on my thermostat mean?

Today’s thermostats can help you make smart decisions about your comfort systems. They can be programmed to provide heating or cooling service around your schedule, remind you to change the filter, or tell you when you need to call a technician. What if it doesn’t say anything? A blank screen could simply mean you need new batteries, so try replacing them. If that doesn’t restore your thermostat, call Gross Heating right away—a non-responsive thermostat will not allow you to control your temperature.

Should my heating and cooling system fan switch be set to “on” or “auto?”

If you’re interested in keeping your energy costs down, use the auto setting so the fan only runs when needed to maintain the set temperature. However, if you prefer a more consistent temperature, use the on setting for uninterrupted airflow. This option may also be beneficial if you have allergies or asthma because air will constantly be filtered as it flows through the system.

Do I need an air test?

Gross Heating offers the AirAdvice for Homes™ test that can identify air quality problems in about one minute. This includes an accurate measurement of the temperature and particle, chemical, carbon dioxide, relative humidity, and carbon monoxide levels in your home. While some may be annoying, particularly if you have allergies, the risk of CO should not be ignored—we recommend a test every other year to protect your family. We also offer testing and mitigation services to protect you from another airborne hazard—radon gas, which can enter your home through even the tiniest cracks in your foundation.
