How to Lower Your Energy Bills in Mount Laurel, NJ

New Jersey has some of the highest residential energy rates in the country, and Mount Laurel homeowners who pay PSE&G every month feel it in every season: higher electric bills in the summer for air conditioning and in the winter for heat. The good news is that the same upgrades that cut those bills can qualify for thousands of dollars in New Jersey rebates and 0% financing, and they often increase what your home is worth when you sell.

This guide walks through how Mount Laurel energy costs compare to the national average, why a home energy audit is the smart first step, which upgrades actually pay off in South Jersey homes, and exactly which 2026 rebate programs to ask about. Whether you live in a mid-century ranch in Southgate or a newer colonial in Stonegate, the same playbook applies.

How High Are Energy Costs in Mount Laurel, NJ?

According to the U.S. Energy Information Administration, New Jersey's average residential electricity rate was roughly 23 cents per kilowatt-hour in late 2025, well above the national average of about 16 to 17 cents. Natural gas for home heating ran around $1.55 per therm, and a typical 100-therm winter heating bill lands between $130 and $150 before delivery charges. Add the hot, humid South Jersey summers and the cold winters in between, and utilities are a real line item in the Mount Laurel cost of living.

In Mount Laurel specifically, PSE&G is the regulated delivery utility for both electricity and natural gas, so the delivery portion of your bill is fixed no matter what. What changes is how much energy your home actually uses, and that part is largely under your control. Homes in this township range from post-war ranches to modern builds, and the older ones, especially the classic mid-century colonials found in Barclay and the Country Club area, tend to leak the most energy. If you would like to see how utility costs fit into the full monthly budget picture, our Mount Laurel cost of living guide breaks down the numbers side by side with property taxes and commuting costs.

How Do You Find Out Where Your Home Is Wasting Energy?

The single best first step is a home energy audit, and in New Jersey it is also the required first step for nearly every state rebate program. An auditor runs a blower-door test that depressurizes your house to find air leaks, uses thermal imaging to reveal missing insulation and cold spots, and produces a certified energy model that determines which incentives you qualify for.

• Ask PSE&G about an audit first. PSE&G covers the cost of a whole-home assessment in many cases, and other New Jersey utilities run audits for roughly $100 to $200. A paid audit is still worth it when it unlocks thousands in rebates.
• Expect blower door and thermal imaging. These two tests find the exact spots where conditioned air escapes, which are rarely where you think they are.
• Ask for the modeled savings number. Your audit report estimates the percentage of energy a package of improvements would save, and that percentage drives how much rebate you get.

Even without a formal audit, a cold autumn evening walk around your home tells you a lot. Run your hand along window and door edges, check the attic hatch, and look at how much insulation is visible in the attic. If you bought one of the charming older homes in Southgate or Holly Hills, chances are good there is room to improve.

Which Upgrades Save the Most in a South Jersey Home?

Not every improvement is worth doing first. The New Jersey Home Performance with ENERGY STAR path pays for up to half of insulation and air sealing work, up to about $4,000, because that is where the biggest, fastest savings live. Heat pumps and high-efficiency water heaters round out the list for homeowners ready to make a bigger move.

• Attic insulation and air sealing. Heat rises, and an under-insulated attic is the biggest single leak in most homes. This is the classic do-it-yourself or contractor project and the first thing auditors recommend.
• Duct sealing in forced-air homes. Leaky ducts in unconditioned basements and attics waste a surprising share of heated and cooled air before it ever reaches a room.
• Cold-climate heat pumps. New Jersey utilities offer rebates of roughly $1,000 to $2,000 on qualifying heat pumps, which both heat and cool efficiently and replace an aging system.
• Weatherstripping and smart thermostats. Cheap, fast, and easy. Door sweeps, window seals, and a programmable thermostat pay for themselves within a season or two.

What Rebates Can Mount Laurel Homeowners Get in 2026?

New Jersey runs the strongest energy incentive programs in the region, and they are worth reading carefully, because the details change year to year. As of 2026, these are the main paths for Mount Laurel homeowners.

• Whole Home Energy Efficiency Program. A $2,000 base rebate once your audit shows at least 5% modeled savings, plus about $200 for each additional point, up to a $7,500 cap. You get 0% financing up to $25,000 repaid on your utility bill over 7 to 10 years.
• Home Performance with ENERGY STAR. Covers up to 50% of insulation and air sealing costs, up to roughly $4,000, when installed by a participating BPI-certified contractor.
• PSE&G equipment rebates. Since PSE&G serves Mount Laurel, your utility rebates stack on top of the state programs. Ask about heat pumps, and note PSE&G also runs a building decarbonization program that can reach $10,000 for qualifying projects.
• Comfort Partners for income-qualified households. If your household income qualifies, Comfort Partners provides no-cost energy-saving measures and weatherization with 100% coverage, delivered through PSE&G and the other utilities.

One honest caveat: the federal Inflation Reduction Act rebates (often called HOMES and HEAR) were still being designed in New Jersey as of mid-2026, so they were not yet open for applications. Do not let that stop you, the state and utility programs above are live today. Start with an audit through PSE&G and ask your contractor to bundle every incentive you qualify for.

Should You Switch to a Third-Party Energy Supplier?

New Jersey deregulated electricity and natural gas in 1999, which means the supply portion of your bill is open to competition even though PSE&G still delivers the energy and reads your meter. Your bill shows a Price to Compare, the default supply rate set through Board of Public Utilities auctions. Licensed third-party suppliers can beat it, but only if you compare carefully.

The official comparison tool is NJ Power Switch, and the rule of thumb is simple: compare the supplier's per-kilowatt-hour or per-therm rate against the Price to Compare printed on your PSE&G bill, read the contract length, and watch for early termination fees and variable rates that can jump later. A good fixed rate can save a modest amount; a bad variable deal can cost you. If a door-to-door pitch promises savings that seem too good to be true, check the numbers against NJ Power Switch before signing anything.

Do Energy Upgrades Actually Raise Your Home's Value?

Yes, and appraisers are taking notice. Energy-efficient homes sell with a measurable premium in many markets, in part because buyers in Mount Laurel are increasingly asking about utility costs before they make an offer. A home with a newer heat pump, sealed ducts, and a well-insulated attic is not only cheaper to run, it is easier to finance and easier to insure, and it appraises for more when everything else is equal.

If selling is on your horizon, energy improvements are one of the few upgrades that can pay you twice: once through rebates and lower bills while you live there, and again at closing when buyers compare your home to similar ones in Ramblewood, Springdale, or along the Route 38 corridor.

Frequently Asked Questions

Start With an Audit, Then Let the Rebates Work

You do not need to replace everything at once. Book an audit, tackle the attic insulation and air sealing, and let the rebate programs cover a meaningful slice of the cost. In a town with high New Jersey rates, energy efficiency is one of the few home improvements that pays you back every single month. And when the time comes to buy or sell, an efficient home is a more valuable home, in Mount Laurel and everywhere else in Burlington County.
