FAQs

We have answers to all of your heating and cooling questions.

When is the best time to replace my furnace?

Don’t wait until your furnace dies to consider replacing it. In an emergency—usually in the dead of winter—you’ll be in such a rush to restore heat that you might not carefully weigh all your options for service and savings, plus it will be more difficult to schedule an install in a timely manner. If you have annual maintenance performed, we’ll be able to catch early warning signs and give you recommendations for a new installation.

Is it cheaper to install an AC with a furnace?

Yes, upgrading your air conditioning or adding air purifying products during a furnace installation will save you an extra trip charge and labor fees. Your Gross Heating technician knows exactly how they work together and is happy to take care of several comfort needs in a single trip.

How often should I service our furnace or boiler?

Annual maintenance is recommended to ensure safe, reliable, and efficient heating through the winter. It’s always a good idea to test and adjust your system before you really need it, so call us up before the temperatures go down.

How often should I replace my furnace filter?

Recommended intervals are as follows: one-inch disposable filters should be replaced monthly while four-inch media cartridges or high efficiency particulate air (HEPA) filters only have to be replaced every six to 12 months. If you smoke indoors, burn candles, have pets, or have construction in your neighborhood, it’s likely you’ll need to replace them more often.

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.

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.
