All AC & Heating, Inc.

Editor's verdict

All AC & Heating is the Staten Island pick in this ranking with the fullest publicly-asserted certification stack. Its company site advertises technician-level NATE certification and EPA Section 608 refrigerant handling, and the entity carries an active DCWP Home Improvement Contractor licence. That combination — licensed at the city level, plus per-technician federal refrigerant handling — is what a homeowner wants for any AC repair that involves refrigerant work, which in NYC covers most central-AC and ductless jobs.

Two nuances shape the verdict. First: NATE and EPA credentials are per-technician, not per-company, and All AC does not publish card numbers on its site. The company statement is a strong signal but not the same as a verifiable card lookup — ask the office to name the specific technician assigned and, if it matters for your building requirements, request the physical EPA card on-site. Second: the founding-year story has two dates. The company advertises "since 1975," while BBB and DCWP records incorporate the current entity in 2016. We treat the corporate registration date (2016) as the verifiable founding of the current legal entity; the 1975 claim may reflect an earlier related business, a family predecessor, or brand heritage that is worth confirming directly with the office.

The review base is small (Google 4.7 across 41 company-stated reviews; Yelp 3.0 across only 4) — not enough volume to draw statistical conclusions from either source alone. In that reality, the DCWP HIC licence, the BBB A+ (unaccredited but no unresolved complaints), and the certification claims do most of the trust-signal work. For a Staten Island residential job with refrigerant scope, All AC is a defensible pick with the questions above answered on the intake call.

Watch-outs

• Small review base. Four Yelp reviews is too few to average meaningfully. Ask the office for three recent references (same borough, same job type) before scheduling a large install.
• Certifications are claimed. The site asserts NATE and EPA 608 without card numbers. Ask which technician is assigned and request the EPA card on-site — EPA 608 is a per-technician requirement under the federal Clean Air Act.
• Founding-year ambiguity. Ask the office to reconcile the "since 1975" claim with the 2016 corporate registration — a related earlier entity, a family predecessor, or brand heritage — so the year in your quote reflects the same story the company tells other customers.
