If your furnace has a pilot light, look for the flame. Check your owner’s manual or the instructions posted inside the furnace cabinet for step-by-step lighting instructions. Usually this involves first turning the gas valve to Off and waiting a couple of minutes. Then you turn it to Pilot. Next, press and hold it down while you light the flame. Last, wait a minute or so, release it, and then turn it to On.

As you decide, insist that the contractor select models in a range of efficiencies and calculate the annual estimated operating cost of each model you're considering, rather than simply estimating it. The contractor can complete those calculations by plugging information on each unit's AFUE and electrical consumption, local utility rates, and characteristics of your home into one of several computer programs designed to easily calculate estimates. Make sure that the quotes also include the cost of any changes to venting required by any appliances in the home.

“Walter Zainey started the Greenwood Furnace Co. in the Greenwood neighborhood of Seattle in 1918 and quickly built a reputation for providing quality products and services. For years we believed Greenwood began in 1921 but only recently, May of 2017, Walter’s granddaughter shared a newspaper ad from 1968 showing that Greenwood was actually founded in 1918! When your company goes back 100 years you are bound to have mixed messages about the history but we now have an accurate founding date and founder. Thank you to the Zainey family and especially Jacklyn for taking the time to share the story with us. I am sure Walter Zainey would be proud the heritage he created is still living on.

To be sure of correct sizing and a proper installation, choose a reputable contractor who will take the time to calculate your heating needs according to an industry standard such as in "Manual J HVAC Residential Load Calculation" of the Air Conditioning Contractors of America. Such calculations take into account the climate and the size, design, and construction of your house. Once the furnace is installed, maintain it regularly according to the manufacturer's recommendations. Our survey helped to confirm this advice. When we asked about the most common reasons for service calls for furnaces, contractors cited human error, inadequate maintenance, for example, or improper installation, twice as often as defective equipment. Read our frequency of repair report for which brands or the most and least reliable.
Even if your air conditioning unit is still working, depending on the type of system in your home today, you could recoup your investment in a new system in as little as three years. However, that doesn't mean that your system needs to be replaced. Furnaces, air conditioners, and other heating and cooling systems have made tremendous gains in efficiency over the past five years, so if you have an older unit, it is worth taking a look at whether or not a repair is the best investment.

Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.

• Furnace is making more noise because it’s turning on and off more frequently. It may need repair, may not have been sized properly to fit the needs of your house, or may not have the airflow available that it needs from the ducts. The ducts are most often the culprit. Sometimes adding a cold air return can solve this. Ensure your vents are all open. If you are closing off vents in your house this can contribute to the issue.
For starters, once a year, vacuum out the area around the furnace’s blower. If possible, also slide out the fan unit, clean each fan blade with a toothbrush, and then vacuum with a brush attachment on a vacuum cleaner. While you’re at it, look for oil ports on the motor, normally located near the motor shaft. If the motor has these, apply two to three drops of non-detergent motor oil into each port (you may have to remove a cover plate to do this). Though most contemporary motors don’t require lubrication, do lubricate motors with oil ports once a year. For more about maintenance, see Maintenance Checklist for Central Heating Systems.
