Quick tip from Chris: Before the no-heat calls pile up, confirm that your general liability policy includes products-completed operations coverage and that your tools and the equipment in your vans are on an inland marine floater. Those are the two gaps I see most often with heating and cooling contractors. In general, an HVAC business in Pennsylvania needs general liability, workers' compensation once it has an employee, commercial auto for its vans, and coverage for tools and equipment. If you do residential work, Pennsylvania's home improvement registration also requires proof of liability insurance.
Every November, the phones at HVAC shops across Central PA start ringing the same way: a furnace that won't light, a heat pump that's icing up, a boiler that sounds like a freight train. It's the busiest, most profitable stretch of the year, and it's also when the biggest claims tend to happen. A missed flue connection, a cracked heat exchanger or a condensate line that backs up into a finished basement can turn a routine service call into a five- or six-figure problem.
From our offices in Hershey and York, we insure contractors across Dauphin, Lebanon, Cumberland, Lancaster, York and Adams Counties, plus Harford, Baltimore and Carroll Counties in northern Maryland. Here's how we look at an HVAC contractor's insurance program.
What insurance does an HVAC contractor need?
Most heating and cooling businesses we work with build their program around a handful of core coverages.
General liability. This responds when your work or your crew causes bodily injury or property damage to someone else, such as a customer who trips over a tool bag or a ceiling stained by a leaking line set. It's the coverage general contractors, property managers and homeowners ask to see first.
Products-completed operations. This is the part of liability coverage that applies after you've packed up and left. For HVAC work, it's often the most important piece, because many claims trace back to an installation or repair that failed weeks or months later.
Workers' compensation. Pennsylvania requires it once you have even one employee (more on that below).
Commercial auto. Service vans and pickups used for the business generally belong on a business auto policy.
Tools and equipment coverage. An inland marine floater can cover tools, gauges, recovery machines and the equipment you're carrying to a job.
Umbrella or excess liability. Larger commercial customers and general contractors often require higher limits than a primary policy provides.
Does Pennsylvania require HVAC contractors to carry insurance?
Pennsylvania doesn't have one statewide HVAC license. Licensing for mechanical trades is handled locally in some municipalities, so check with each township, borough or city where you pull permits.
What does apply statewide is the Home Improvement Consumer Protection Act (HICPA). According to the Pennsylvania Attorney General's office, contractors who do $5,000 or more of home improvement work in a calendar year must register, and the definition of home improvement includes installing central heating and air conditioning. To register, the AG requires proof of at least $50,000 of personal injury liability coverage and $50,000 of property damage coverage. Registration costs $50 and must be renewed every two years.
Those are minimums, not recommendations. A single furnace fire or water loss can exceed $50,000 quickly, and many commercial customers ask for $1 million per occurrence or more.
What if I also work in Maryland?
Maryland does license HVACR contractors through the Maryland Department of Labor. The Department's HVACR board requires licensed contractors to carry at least $300,000 in general liability and $100,000 in property damage liability, for a combined $400,000. If your trucks cross the line into Harford, Baltimore or Carroll County, make sure your certificate shows limits that meet those rules.
Why does completed-work coverage matter so much for heating jobs?
Heating equipment involves combustion, gas, electricity and water, often in the same mechanical room. A claim might come from a fire, carbon monoxide exposure, a refrigerant leak or water damage from a clogged condensate drain, and it may not show up until long after the invoice is paid.
Products-completed operations coverage is typically included in a contractor's general liability policy, but limits, exclusions and how the aggregate is shared vary by carrier. Some policies also carry exclusions that matter to HVAC work, so it's worth reading the endorsements, not just the declarations page.
Are my tools and the equipment in my van covered?
Often, not by your property or auto policy alone. The Insurance Information Institute (Triple-I) notes that standard property insurance typically doesn't cover equipment that moves from place to place; that's what floaters are for. Two are especially useful for HVAC shops:
A tools and equipment floater covers your hand tools, power tools, vacuum pumps, recovery machines and similar gear wherever you use them.
An installation floater covers equipment such as a new furnace, air handler or condenser while it's in transit, being installed and being tested at the customer's site, before ownership passes to the customer.
Theft from vans is a common claim in our area, so ask how your policy handles tools left in a locked vehicle overnight.
Do I need workers' comp if I only have one helper?
In Pennsylvania, yes. The Department of Labor & Industry says any employer with at least one employee who could be injured on the job in Pennsylvania must carry workers' compensation, and part-time workers and family members count. Sole proprietors with no employees are generally excluded. The penalties for going without are steep, including potential fines and criminal charges for each day of violation.
HVAC work carries real injury exposure: ladders and roofs, attics in summer, crawl spaces, heavy equipment and sheet metal. Your workers' comp premium is based on payroll and job classification, so keeping clean payroll records and certificates from any subcontractors helps avoid surprises at audit time.
What else should HVAC contractors think about?
Refrigerant handling. The EPA requires technicians who maintain, service, repair or dispose of equipment that could release refrigerant to hold Section 608 certification. Certification isn't insurance, but carriers often ask about it, and a pollution exclusion on your policy may affect how a refrigerant release claim is handled.
Certificates and contracts. General contractors and property managers will ask to be named as additional insureds, and hold-harmless clauses can shift liability onto you. We're happy to look over the insurance section of a contract before you sign.
Frequently asked questions
How much general liability insurance should an HVAC contractor carry?
Pennsylvania's HICPA registration minimum is $50,000 of personal injury and $50,000 of property damage coverage, and Maryland requires more for licensed HVACR contractors. Many contractors in our area carry $1 million per occurrence and $2 million aggregate because that's what commercial customers and general contractors commonly require.
Does general liability cover my own faulty workmanship?
Usually not. General liability typically responds to damage your work causes to other property or to injuries, not the cost of redoing your own work. Every policy is different, so check the wording.
Do I need commercial auto if my van is in my name?
If the vehicle is used mainly for business, a personal auto policy may not cover it. Triple-I notes that business vehicles generally need a business auto policy. We can review how your vehicles are titled and used.
Are my subcontractors covered under my workers' comp?
If a subcontractor doesn't have their own workers' comp, your policy may end up covering them, and the auditor may charge you for their payroll. Collect current certificates from every sub before they start work.
Does Pennsylvania require an HVAC license?
There's no single statewide HVAC license in Pennsylvania; some municipalities have their own requirements. Residential contractors above the $5,000 threshold must register under HICPA, which requires proof of liability insurance.
