The northern half of New Jersey averages about 10 degrees cooler than the south during the winter, averaging in the mid-thirties. However, in the summertime the temperature generally remains constant throughout the state.
New Jersey is roughly 70 miles wide and 150 miles long. It also has an east coast bordered by the Atlantic Ocean. NJ is unusual in that a few of its counties are located within the municipal areas of other states - in particular the city of New York, New York, and Philadelphia, Pennsylvania. Like New York, New Jersey's cities are densely populated, but when you get away from the cities, you'll find that there's plenty of farm and woodland too.
Also like New York, New Jersey has no state licensing laws for HVAC contractors. Consumers and contractors therefore need to check their local jurisdictions for any particular requirements.
If you have a problem with a New Jersey heating, ventilator or air conditioning contractor, contact the Attorney General's Department of Consumer Affairs using their complaint form.
For any low-income homeowners having difficulty paying their heating bills, LIHEAP (Low Income Home Energy Assistance Program) offers assistance.
