Frequently Asked Questions

How often should I service my HVAC system?
Most manufacturers recommend a professional tune-up at least once a year for each system you own — once for your air conditioner in the spring, and once for your furnace or boiler in the fall. Regular maintenance catches worn parts, refrigerant leaks, and airflow problems before they turn into breakdowns, and it's often required to keep a manufacturer's warranty valid. Our Long Island technicians inspect electrical connections, clean coils, check refrigerant levels, and test safety controls at every visit.
Do you offer free estimates?
Yes. Call us or fill out our contact form and we'll schedule a free, no-obligation estimate for installation or replacement projects anywhere in Nassau or Suffolk County. We'll evaluate your home or business, walk you through your options, and give you a written quote before any work begins — with our Price Match Guarantee backing every estimate against a competitor's written quote.
What size HVAC system do I need?
The correct size depends on your home's square footage, ceiling height, insulation quality, window count and orientation, and local climate — not just a rule of thumb. An undersized system runs constantly and never keeps up; an oversized one short-cycles, wastes energy, and wears out faster. Our technicians perform a load calculation on-site and recommend the properly sized central air, ductless, or heating system for your specific home.
Are your technicians licensed and insured?
Yes. Able Air Heat has been licensed and insured on Long Island since 1999. Our technicians are trained and certified across all major heating and cooling brands, including Carrier, Trane, York, Rheem, Navien, American Standard, Goodman, and Mitsubishi, so you can expect factory-trained service regardless of what equipment you already have installed.
Do you offer emergency service?
Yes. We provide 24/7 emergency heating and cooling service across Nassau and Suffolk County, including nights, weekends, and holidays. Emergency calls are billed at our same flat-rate pricing — no overtime surcharges — for repairs like no heat, no cold air, boiler failures, and hot water heater outages.
What towns and areas do you service?
We serve homes and businesses throughout Nassau and Suffolk County, Long Island, including Oceanside, East Rockaway, Lynbrook, Rockville Centre, Freeport, Baldwin, Long Beach, Hempstead, Garden City, Valley Stream, Merrick, Massapequa, and surrounding communities. If you're unsure whether we cover your area, call us at (516) 764-4300 and we'll let you know right away.
Do you offer financing?
Yes. We offer 0% interest financing on qualifying central air conditioning, heating, and system replacement installations, so you can get the comfort you need now and pay over time. Ask about current financing terms when you schedule your free estimate.
