Maria Franco has lived in the Park Royale Mobile Home Community for 25 years, in the Van Nuys neighborhood in north Los Angeles. The community has just under 150 rectangular homes, lined up neatly on a large field of mostly asphalt, with fruit trees popping up here and there.

Two years ago, Franco faced a string of bad luck. The 65-year-old lost her long-time job packing orders at a distribution company when it abruptly moved to another county, a commute too far for her to make.

Then her hot water heater clonked out, so she hauled warm water from her stovetop to her bathroom, scooping it over her head for a shower.

“I was depressed,” Franco said in Spanish. “I was in shock.”

The Southern California summer bore down harshly where she lived in the San Fernando Valley, its temperatures regularly 10 to 15 degrees higher than those on the coast.

To cool off, Franco relied on a fan and a partially functional window air conditioning unit. When her adult kids and grandchildren came by, they found the heat inside oppressive.

A knock on her door changed all that. A young contractor named Ben Shamoon stood on her step, wanting to know if he could install a new water heater, and an HVAC system that both cooled and heated her home. The cost to Franco? Absolutely nothing.

“It was an inexplicable experience, a blessing from heaven,” Franco said.

Shamoon won over customers by canvassing trailer parks. By working with families who lived in close proximity, he could buy in bulk and work more efficiently to complete projects faster. The approach maximized incentives from a state program — aimed at supercharging heat pump adoption — to improve homes at no cost to owners.

He found a climate solution with a lot of wins — for customers, tradespeople and the planet. The approach cracked the nut of one way to bring heat pumps, which run on electricity rather than gas, to low-income Californians.

Best of all, Shamoon brought safety and comfort to families.

Cold calls to San Diego

In July of 2024, Shamoon was working to get his home upgrading business Bryge, then called LivSmart Home Services, off the ground. Tons of state and federal money was flowing to homeowners and contractors at the time through an initiative called TECH Clean California, to help deploy appliances like heat pumps that cut pollution. Low-income customers received the highest incentive.

Shamoon is based in Los Angeles, but the government incentives in the current funding cycle were exhausted in most parts of the state. He saw that there was some money left — about a million dollars to install heat pump water heaters for low-income customers in San Diego.

Shamoon often passed by a mobile home community at the end of his street. One day, an idea came: why not pitch mobile homeowners on the upgrades?

He could install the units at no cost to the customer and the roughly $8,885 incentive per job would be enough to pay for the equipment, labor, permits and profit.

Shamoon and a colleague found a list of San Diego mobile home parks and started cold-calling managers’ offices. Most said no, he could not go door to door, hoping to keep predatory schemes away from residents. Shamoon’s offer of free upgrades was hard to believe.

But a few said yes.

Door-knocking his way through each community, Shamoon picked up clients.

He found that — along with a higher concentration of potential customers — the mobile home parks were home to many families who made under 80% of the median income in the area, which meant they qualified for state assistance, and higher incentives.[aside postID=science_2001163 hero='https://cdn.kqed.org/wp-content/uploads/sites/35/2026/06/20260531-RENTERSELECTRIFY-JY-15-KQED.jpg']“We started to see a trend,” Shamoon said. Not only did most customers qualify for incentives, but like Franco, they needed the help.

He met senior citizens who’d been living without working hot water heaters for months. And people with no air conditioning on days when outside temperatures exceeded 100 degrees.

“It was just one door after the next, after the next,” Shamoon said. He started to see his work as not just about comfort, but about dignity.

As installations began, Shamoon stumbled on wins. Sending contractors to one community cut down on commute times and meant he could get three to four jobs done in a day, as opposed to just one or two. He could bulk order supplies and get lower prices.

After he and his colleagues first canvassed mobile home parks, word traveled fast through the tightknit communities.

People who had initially turned his company away visited their neighbors’ homes and were assured that they had indeed paid nothing for their fancy new appliances. They called Shamoon back and wanted in.

For most customers who had older, inefficient air conditioners and live in hot, dry areas, their monthly bills went down noticeably.

The process was not without challenges: electrical panels in some homes did not have capacity to power the upgrades. Different mobile home parks had restrictive rules about where appliances could be placed on the outside of homes.

But Shamoon was not deterred. He repeated the process, adding installations of heat pumps to warm and cool homes.

In the beginning, he worked with homeowners of all income levels, as there were incentives for people with high incomes too, but he eventually zeroed in on low-income homeowners.

Wealthier clients proved high-maintenance, despite getting free appliances, he said. Low-income families were incredibly grateful, and experienced a dramatic improvement in their quality of life.

Hundreds of miles north in Oakland

Consultant Evan Kamei started to take notice.

He had never met Shamoon, nor heard of his company before he started seeing its name pop up on spreadsheets. Kamei works in Oakland for Energy Solutions, an environmental consulting company that implements the state’s incentive program.

Kamei realized more and more mobile homeowners were participating in the program thanks to Shamoon.

His company has installed the majority of the roughly 1,500 TECH-funded heat pump HVAC and water heaters in mobile homes statewide. California’s incentive program has funded about 80,000 heat pump installations on all types of homes.

In Franco’s mobile home park, Shamoon has completed 38 projects.

“That’s the beauty of having a market-based solution of enabling contractors to figure out something that could work,” Kamei said, reflecting on contractor creativity, “It’s not something you typically see with an incentive program like this.”

A lot of wins, and some limits

What Shamoon is doing, swapping gas-powered heating and cooling for electric versions of appliances, lowers carbon pollution by pulling from the state’s mostly green grid. But it also could improve indoor air quality.

Esperanza Sanchez is breathing easier after she upgraded her HVAC system to a heat pump with Shamoon’s help. Sanchez lives in the Blue Star Mobile Home Park in the San Fernando Valley’s Sylmar neighborhood.

Sanchez had previously avoided using her gas heater because it triggered her asthma. “It stung my nose and I couldn’t stand it,” Sanchez said in Spanish. After making the switch, she said her respiratory issues were gone.

“It’s a public health thing. It’s an equity thing,” said Ethan Elkind, a UC Berkeley lawyer and policy researcher who’s studied how low-income Californians can adopt more planet-friendly appliances.

“It’s almost a human rights thing in these really hot climate zones — giving people access to reliable air conditioning,” Elkind said. “It checks a lot of boxes for what we need to do.”

But there are limits to this solution. There’s no way for the state to provide incentives for every low-income Californian to make the switch. California has doled out more than $219 million so far, but bringing electric appliances to all low-income residents would cost in the hundreds of billions of dollars, Elkind said, money the state does not have.

A settlement from a 2016 gas leak in the San Fernando Valley will funnel roughly $30 million in incentives to nearby residents through TECH starting late this summer. It’s unclear when these funds will again be available for Californians who live outside that region, and are not eligible for the settlement money.

One way to stretch the state’s limited funds is to use public dollars to attract private investors, Elkind said. Under this model, the state pays the interest upfront — giving low-income homeowners access to no-interest loans — and covers the loss if a borrower defaults. This safety net eliminates risk for private lenders, allowing them to finance the initial equipment upgrades. Homeowners would then pay back the loan principal over time, using the savings many see from now lower utility bills.

But that could only go so far. National policies incentivizing heat pump adoption like those in the Biden Administration’s Inflation Reduction Act, done away with under the Trump Administration’s tax bill, would need to be reinstated to achieve large-scale adoption.

Reaching renters is another story. Gas appliances are cheaper upfront. So landlords have little financial incentive to make the switch — while there are bill savings, those go to renters.

Elkind said achieving this shift would take policies like those slated to roll out in the Bay Area in 2027, requiring all new water heater installations be electric.

The most glaring limit is California’s high cost of electricity. For many, monthly bills for a gas appliance are lower than electric alternatives. But for Californians like Franco, who replaced old, inefficient window air conditioners, their bills often go down. That’s because new technologies use less energy to do the same – and often a better – job.

Cool air, hot showers

Three months after that knock on her door, Franco watched two men install her new water heater. It had been half a year since she had the ability to step into her shower, turn a knob and have hot water come out.

“That first time using the shower was beautiful,” Franco said.

A month later, she welcomed a new mini-split heating and cooling unit, blowing crisp air in her living room.

The single unit is powerful enough to transform her two-bedroom home from oppressive to refreshing in just 15 minutes.

Before the changes, her gas bill, which covered her furnace, water heater and stove, was $40 to $50 per month. It is now just $10. Her electricity bill went from $150 to around $80. The savings are meaningful given her monthly social security benefits of $1000.

Without Shamoon and his coworkers, Franco would have never learned about the state incentives, and never made the change.

“When I needed help the most, it came,” Franco said. “If it weren’t for them, we’d be suffering from the heat.”
