Why Hire Qualified HVAC Technicians?

When your heating or cooling system needs service, it can be tempting to go with the cheapest option. But HVAC work involves refrigerants, electrical systems, gas lines, and complex mechanical components — the stakes for getting it wrong are high.

EPA Section 608 certification is required by federal law for any technician who handles refrigerants. This certification ensures the technician understands proper refrigerant handling, recovery, and disposal — protecting both the environment and your equipment.

NATE (North American Technician Excellence) certification is the gold standard for HVAC technicians. NATE-certified technicians have passed rigorous exams covering installation, service, and troubleshooting across all major HVAC systems.

In Pennsylvania, HVAC contractors performing home improvement work must be registered with the Pennsylvania Attorney General's office under the Home Improvement Consumer Protection Act. Always ask for a contractor's PA HIC registration number — Heirloom Mechanical's is PA196206.

Beyond certifications, look for contractors who carry general liability insurance and workers' compensation coverage. This protects you if something goes wrong on the job. Ask for proof of insurance before any work begins.

At Heirloom Mechanical, all of our technicians are fully certified, insured, and background-checked. We believe you deserve to know exactly who is coming into your home — and that they have the training to do the job right the first time.
