About Farrell Insulation
Farrell Insulation has operated from Salisbury since 1997, building a client base across five North Carolina metros including Charlotte, Greensboro and Winston-Salem. The contractor holds a five-star rating derived from over 2100 client reviews, reflecting consistent execution across residential, commercial and multi-family projects. Core offerings span insulation upgrades, duct repair and comprehensive weatherization services tailored to structures both new and existing.
What distinguishes Farrell Insulation is its established relationship with regional utility providers, enabling homeowners to access rebates through programs including Duke EnergySaver initiatives. The company participates in income-qualified weatherization (IQWP), residential efficiency (EASE) and multi-family housing improvement pathways, providing documented pathways to utility bill reductions. This direct referral network differentiates the contractor from independent generalists lacking verified program eligibility.
Named technicians appear repeatedly in Five-Star reviews. Diante and Caleb earned praise for explaining each assessment step while winterizing a Duke Energy participant's home; the reviewing homeowner noted feeling secure despite being unaccompanied. Alex and Alexis similarly completed insulation work on a separate property, with the reviewer emphasizing their systematic approach and leaving the space improved. Technicians Sean P, Omari and Alex T received commendation for walking a homeowner through permission-gated repairs, ensuring transparency throughout the process.
What Customers Say
Of 2,118 reviews, the contractor maintains a 5.0 average across both five-star entries and one critical assessment. Positive reviews consistently cite named technicians' communication and systematic workflow; the sole negative review documents a property damage claim tied to a Duke Energy program installation with unresolved follow-up as of January 2026.
