How to choose an HVAC company in Ronkonkoma
- Ask for a load calculation before you replace a system, not just a size match.
- Compare efficiency ratings (SEER2/AFUE) and available rebates.
- Ask what maintenance plans cost and what they cover.
Check the license: your city or county licensing office (in New York City, the Department of Consumer and Worker Protection licenses home improvement contractors).
