Chimney Services in Berkeley Heights, NJ
About nine in ten Berkeley Heights homes heat with gas. A gas appliance depends on its vent to carry exhaust out of the house, and this page explains how that vent, carbon monoxide alarms and a yearly check fit together.

What the numbers suggest for chimneys in Berkeley Heights
Census estimates show about 91% of Berkeley Heights's occupied homes heating with utility gas, with electricity at about 6% and fuel oil at 2%. For most households, the flue or metal vent serving the furnace, boiler and water heater is the hardest-working part of the venting system, in use every day of the heating season.
About 33% of the township's 4,905 housing units date from 1940 to 1959 and 35% from the 1960s and 1970s. Chimneys of that age that once vented older equipment may now serve newer appliances with different venting needs, a mismatch explained in the guide to the orphaned water heater.
About 84% of units are detached houses. The numbers describe the township, not the condition of any one vent.
How a gas vent can fail without anyone noticing
Gas burns cleanly enough that a gas flue rarely fills with soot the way a wood or oil flue can, which is exactly why it gets overlooked. CSIA's FAQ points out that a gas chimney can still stop working when bird nests or other debris block it. Other problems are quieter: a connector pipe that has slipped loose at the chimney, a liner damaged by condensation, or a flue too large for a water heater left behind after a furnace upgrade.
When exhaust cannot get out, it can spill back into the house, and carbon monoxide cannot be seen or smelled. Our guide to carbon monoxide and your chimney covers how that happens.
What you can look at near the furnace
From a few feet away, with the appliances running normally, look at the vent connector between each appliance and the chimney. It should rise toward the chimney, be joined tightly at each seam and sit firmly in the chimney opening. Rust holes, streaks at the joints, a pipe that has dropped away from the wall, or tape holding joints together are reasons to call for an inspection. Do not touch the pipe while the appliance runs, since it gets hot, and do not try to refit it yourself.
If a CO alarm sounds. Get everyone out of the house and call 911 from outside. Do not go back in to look for the cause.
Alarms and yearly checks do different jobs
An alarm warns you when carbon monoxide is already in the air; an inspection looks for the conditions that could put it there. The U.S. Consumer Product Safety Commission recommends CO alarms with battery backup on every level of the home and outside sleeping areas. New Jersey's Department of Community Affairs, in its Bulletin 99-3, describes CO alarm requirements for homes that contain fuel-burning appliances or have attached garages, with alarms in the immediate vicinity of sleeping rooms. Our guide to CO alarm placement and testing goes further.
On the venting side, CSIA quotes NFPA 211 as calling for chimneys, fireplaces and vents to be inspected at least once a year. In a gas-heated home that yearly visit includes furnace and boiler flue cleaning where needed, a look at the cap, and a check of the connector and its joint at the chimney.
Local questions
Our furnace burns gas. Does its chimney really need yearly attention?
Yes. NFPA 211, as quoted by CSIA, calls for chimneys and vents to be inspected annually, and CSIA notes that gas flues can be blocked by nests or debris.
Where should CO alarms go?
CPSC recommends them on every level of the home and outside sleeping areas, and New Jersey's rules call for them near sleeping rooms in homes with fuel-burning appliances or attached garages. Follow the alarm maker's instructions as well.
We notice an odd smell near the water heater. What should we do?
If you smell gas, leave the house and call your gas utility or 911 from outside. For other odors near a gas appliance, stop using it and have the appliance and its vent checked before using it again.
Our water heater vents into the old chimney. Is that a problem?
Not by itself. It depends on whether the flue is lined, sized for the water heater and in good condition, which matters most if the furnace beside it was replaced with a model that vents elsewhere.
