Common questions

Air Conditioning FAQs

How do I know if I need AC repair or a full replacement?

If your AC is under 10 years old and the repair cost is less than half the price of a new system, repair usually makes sense. If it's over 12–15 years old, requires frequent repairs, or uses R-22 refrigerant, replacement is often the smarter investment.

How long does AC installation take on Long Island?

A standard central AC replacement typically takes one day. New installations that require ductwork may take two to three days. We'll give you a clear timeline before we start.

Do you install ductless mini-split systems?

Yes. We install ductless mini-split systems from Mitsubishi, Daikin, and other leading brands. Mini-splits are ideal for homes without existing ductwork, room additions, or for zoned cooling.

Why is my AC blowing warm air?

Common causes include low refrigerant, a dirty air filter, a failed compressor, or a frozen evaporator coil. Call A1 at 631-331-2102 for a diagnosis — we offer same-day AC repair across Long Island.

How often should I have my AC serviced?

We recommend an annual AC tune-up every spring before the cooling season. Regular maintenance improves efficiency, extends system life, and helps catch small issues before they become expensive repairs.
