Columbia Gas Home Energy Assessment starts with a technician standing in a quiet hallway, infrared camera in hand, tracing the faint blue outline of a cold spot around an old window frame. The service turns NiSource’s gas utility know-how into a practical home visit aimed at cutting bills and boosting comfort.
What the home visit includes
Columbia Gas Home Energy Assessment is offered by NiSource’s Columbia Gas utilities in select states, including Ohio and Pennsylvania, as a residential efficiency service for natural gas customers. During the visit, a trained energy advisor walks through the home, checking heating equipment, insulation, windows, and air sealing opportunities.
In Ohio, Columbia Gas describes the assessment as a full-home energy audit that can include diagnostic testing such as blower door tests to measure air leaks and combustion safety checks for gas appliances. Customers receive a written report with recommended upgrades and information about rebates, often focused on high-efficiency furnaces, smart thermostats, and building envelope improvements.
NiSource and its efficiency programs

Pricing, rebates and US availability
For US households, the hook is simple: Columbia Gas Home Energy Assessment can be low cost or even free, depending on the program structure in each state. In Ohio, Columbia Gas lists a customer co-pay of around 50 dollars for standard audits, with deeper assessments in some cases tied to weatherization partnerships.
In Pennsylvania, Columbia Gas highlights that certain income-qualified customers may access enhanced audits and upgrades at reduced cost or no cost, in line with state-approved efficiency plans. Availability is confined to Columbia Gas service territories; a customer must already receive natural gas service from Columbia Gas to schedule the visit, typically by phone or online request.
Inside NiSource’s efficiency play
For NiSource, the Columbia Gas Home Energy Assessment program is less about selling a gadget and more about steering regulated efficiency spending into services that households can touch and see. NiSource’s chief executive Lloyd Yates has repeatedly framed energy efficiency as a pillar of the company’s transition strategy, arguing in recent earnings calls that customer-focused programs reduce long-term usage and support climate goals.
That policy backdrop matters in the living room. An advisor might point at a humming, older furnace and explain, in plain terms, how a high-efficiency model paired with tighter ductwork could shave 10 to 20 percent off winter gas usage, depending on the home’s baseline. These numbers flow back into NiSource’s filings: the company reports cumulative gas savings by program category to state regulators, often in terms of million therms reduced.
How the assessment works in practice
On the ground, Columbia Gas Home Energy Assessment is executed by a mix of utility-employed auditors and contracted energy service firms, depending on the state program design. Program managers such as Columbia Gas of Ohio efficiency lead Lisa Miller oversee training, quality control, and the integration of audit results into rebate workflows, according to state-level filings and program descriptions.
A typical visit can last two to three hours. The advisor will usually start at the basement furnace or boiler, checking flue pipes, gas connections, and filter condition. They often carry a handheld combustion analyzer to confirm that appliances are burning cleanly and within manufacturer specifications. Later, they move through rooms checking for drafts around outlets and baseboards, sometimes using a smoke pencil or thermal camera to visualize hidden leaks.
From report to action
The output of a Columbia Gas Home Energy Assessment is a written report, sometimes delivered on paper at the end of the visit and later accessible online. It prioritizes measures based on estimated savings, cost, and available rebates. High-impact recommendations frequently include upgrading to a high-efficiency furnace or boiler, installing smart thermostats, adding attic insulation, and sealing major air leaks.
For NiSource, those recommendations feed a regulated pipeline of incentive spending. State public utility commissions require detailed reporting on program costs and achieved savings, and Columbia Gas aligns its home energy assessments with those filings so that the utility can earn allowed returns on efficiency investments. The interplay of customer comfort, lower bills, and regulatory metrics gives the product a dual identity: it is both a household service and a compliance tool.
Customer experience and first-hand impressions
From a customer’s vantage point, the Columbia Gas Home Energy Assessment feels less like a sales pitch and more like a guided tour through the invisible physics of a house. The advisor might gently press a hand against a chilly exterior wall on a windy day, demonstrating how missing insulation turns heating into a losing battle. That kind of tactile moment tends to stick more than a line in an email.
NiSource emphasizes in its materials that auditors are not there to sell specific brands of equipment, but to highlight efficiency opportunities and connect customers with approved contractors and rebates. Independent reviews from energy bloggers and local news outlets describe the experience as structured and fairly technical, with advisors explaining terms like "U-value" for windows or "R-value" for insulation in plain language.
Impact on usage and billing
For US retail investors and homeowners, the key metric is gas saved per home. NiSource’s sustainability reporting indicates that its gas efficiency programs, including home audits, have delivered cumulative savings in the tens of millions of therms over several program cycles, translating into sizable avoided emissions.
At the individual level, Columbia Gas suggests that a typical home implementing recommended measures can trim gas usage by around 10 to 30 percent, depending on starting efficiency and the scope of upgrades. For a household spending 800 dollars per year on gas, that could mean roughly 80 to 240 dollars less on annual bills after improvements, before considering any changes in gas commodity prices.
Regulatory and policy context
Columbia Gas Home Energy Assessment sits within formal efficiency plans approved by state public utility commissions. In Ohio, for example, Columbia Gas’s plan filings detail budgets, target savings and cost-effectiveness tests, often using metrics like the Total Resource Cost test to evaluate whether programs deliver net benefits to customers and the system.
NiSource, as the parent holding company, aggregates these program outcomes and highlights them in investor presentations as part of its ESG narrative. Analysts following NiSource stock often treat efficiency programs as stable, regulated investments that earn allowed returns and support rate base growth without the volatility of commodity trading or unregulated businesses.
