Common AC Installation Issues We Resolve in Islip

Aging R-22 Freon Systems

Phased-out R-22 refrigerant makes repairing older 10-15+ year systems prohibitively costly compared to high-efficiency R-410A/R-454B upgrades.

Hot & Cold Second-Story Temperature Imbalances

Undersized duct trunks and single-speed equipment unable to push sufficient conditioned air to upper floor bedrooms.

Excessive Long Island Summer Humidity

Oversized, short-cycling legacy air conditioners that cool rooms too quickly without running long enough to wring moisture from indoor air.

Skyrocketing Electric Bills

Older 10 SEER units that consume double the electrical wattage of modern 18+ SEER2 variable-speed inverter systems.
