HVAC work involves gas lines, electrical systems, refrigerants, and combustion equipment. Done correctly, it keeps your home safe and comfortable. Done incorrectly, it can create safety hazards, void equipment warranties, and cost significantly more to fix than it would have cost to do right the first time. The qualifications of the technician doing the work matter.

EPA Section 608 certification

Federal law requires that any technician who purchases or handles refrigerants must hold EPA Section 608 certification. This certification covers the safe handling, recovery, and disposal of refrigerants used in stationary air conditioning and refrigeration equipment. A technician without this certification cannot legally handle refrigerants — and a contractor who employs uncertified technicians for refrigerant work is operating outside the law.

Insurance and licensing

In Pennsylvania, home improvement contractors are required to register with the Attorney General's office under the Home Improvement Consumer Protection Act. Ask for the contractor's PA HIC number and verify it. General liability insurance protects you if something goes wrong on your property. Workers' compensation insurance protects you from liability if a technician is injured on your job. Ask for certificates of insurance before work begins.

Questions to ask before hiring

Ask any HVAC contractor: Are your technicians EPA 608 certified? Are you registered under Pennsylvania's Home Improvement Consumer Protection Act? Are you fully insured, including workers' compensation? Do you pull permits where required? Will you provide a written estimate before starting work? A contractor who cannot answer these questions clearly is a contractor to be cautious about.
