Licensed & Insured HVAC in Hyattsville, MD

The most expensive HVAC mistake a homeowner makes is not choosing the wrong equipment — it is hiring someone unlicensed and uninsured. When an unlicensed installer damages your home, injures themselves on your property, or vents a furnace incorrectly and creates a carbon monoxide hazard, the liability can land on you. Licensing and insurance are not bureaucratic boxes; they are the difference between a problem being the contractor’s and a problem being yours. Here are Swellfort’s credentials, in full, so you can verify them before you ever let a truck into your driveway. All license and policy numbers below are placeholders in the correct format — Marvin replaces them with the actual credentials before publish.

Maryland HVACR Contractor License

Swellfort Heating & Air Conditioning operates under Maryland HVACR contractor license #01-148326, issued through the Maryland Board of Heating, Ventilation, Air-Conditioning and Refrigeration Contractors, part of the Maryland Department of Labor. This is the state credential legally required to perform HVAC work in Maryland. It is not optional, and it is verifiable: anyone can look up a Maryland HVACR license through the state’s public licensing records. We encourage you to. A contractor who hesitates to give you a license number is telling you something.

EPA Section 608 Certification

Owner Marvin Federico holds EPA Section 608 Universal certification #608U-2011-337194. Federal law under the Clean Air Act requires this certification for anyone who handles refrigerants — the R-410A in most current systems, the R-22 in older ones, and the R-454B and other A2L refrigerants in new equipment under the AIM Act phasedown. Universal certification covers all equipment types. Handling refrigerant without it is a federal violation, and improper handling vents potent greenhouse gases and can leave your system undercharged and failing.

WSSC Water Gasfitter License

Gas work in Prince George’s County is regulated separately from the state HVACR license, through WSSC Water. Swellfort performs gas piping and connection work under WSSC gasfitter license #GF-72241. This matters specifically for furnace, boiler, and gas-line work, where an improper gas connection or venting error is not a comfort problem — it is a fire and carbon monoxide risk. Many contractors quietly skip this credential and do gas work they are not licensed for. We hold it and work within it.

Fully Insured — General Liability & Workers’ Compensation

Two insurance policies protect you when we work on your property:

• General Liability — $2,000,000 aggregate through [INSURER NAME]. If our work damages your home — a wall, a floor, the structure — this covers it. Without it, you would be pursuing an uninsured contractor in court for repairs.
• Workers’ Compensation — active coverage through [CARRIER NAME]. This is the one homeowners most often overlook. If an uninsured contractor’s technician is injured on your property — falling from an attic, hurt moving equipment — you can be held liable for medical costs. Workers’ comp moves that liability off you entirely.

We carry certificates of insurance and will provide them on request. For larger or commercial jobs, we can have our insurer send a certificate naming you or your property directly.

Permits: Licensing in Action

Being licensed is what lets us pull permits, and we pull them on every installation through the Prince George’s County Department of Permitting, Inspections and Enforcement. A permit means a county inspector independently verifies the work meets code. Unpermitted work — common from unlicensed installers — routinely surfaces during a home sale, when a buyer’s inspector flags it and the sale stalls until it is corrected and re-permitted, at your expense. Our permits protect the resale value of your home, not just its comfort.

How to Verify Us Before You Hire

You should never take a contractor’s word for their credentials, including ours. Here is how to check:

• Maryland HVACR license — searchable through the Maryland Department of Labor’s public license verification system using our license number above.
• EPA 608 — ask to see the certification card; we will show it.
• Insurance — request a certificate of insurance, which we provide on request and which comes directly from our insurer.
• Permits — the permit number for your job appears on your invoice and is on file with the county.

Frequently Asked Questions

Is Swellfort a licensed HVAC contractor in Maryland?

Yes. Swellfort operates under Maryland HVACR contractor license #01-148326, issued by the Maryland Board of Heating, Ventilation, Air-Conditioning and Refrigeration Contractors under the Maryland Department of Labor. This is the state credential legally required to perform HVAC work in Maryland, and it is publicly verifiable through the Department of Labor’s license lookup. We provide our license number openly precisely so you can confirm it before hiring.

Why does gas work require a separate license?

In Prince George’s County, gasfitting is regulated by WSSC Water, separately from the state HVACR contractor license. This means a contractor can hold a valid HVAC license and still not be licensed to perform the gas piping and connection work that furnaces, boilers, and gas lines require. Swellfort holds WSSC gasfitter license #GF-72241, so our gas work is properly licensed. This matters because an improper gas connection or venting error creates fire and carbon monoxide risks, not just comfort issues.

Why should I care whether my HVAC contractor carries workers’ compensation?

Because without it, you could be financially liable if a technician is injured on your property. If an uninsured contractor’s worker falls from your attic or is hurt handling equipment, their medical costs can become your responsibility. A contractor who carries active workers’ compensation coverage moves that liability entirely off you. It is the single most overlooked protection in hiring an HVAC company, and we carry it on every job.

What happens if unlicensed, unpermitted work was done on my home?

It commonly surfaces at the worst time — during a home sale, when a buyer’s inspector identifies HVAC work that was never permitted or inspected. The sale can stall until the work is evaluated, corrected to code, and re-permitted, at your expense. Beyond resale, unpermitted work was never independently verified for safety, which is a real concern with gas and electrical connections. If you suspect prior unpermitted work, we can inspect the system, identify code issues, and help bring it into compliance.

Can you prove your insurance before starting a job?

Absolutely. We carry certificates of insurance for both general liability and workers’ compensation and provide them on request. For larger residential projects or commercial work, we can have our insurance carrier issue a certificate naming you or your property as a certificate holder directly. You should ask any contractor for proof of insurance before work begins, and we make it straightforward to get ours.
