Most residential AC installations take one full day, though larger homes or complex installations might require two days. The timeline depends on your home’s layout, whether ductwork modifications are needed, and the type of system being installed. We’ll give you a realistic timeframe during our initial assessment so you can plan accordingly. Our team works efficiently while maintaining quality standards, and we’ll keep you updated throughout the process if anything changes.
AC size depends on your home’s square footage, ceiling height, insulation quality, window placement, and local climate factors. A system that’s too small won’t cool effectively, while an oversized unit will short cycle and waste energy. We perform detailed load calculations during our assessment to determine the right capacity for your specific home. This isn’t guesswork – proper sizing is critical for efficiency, comfort, and equipment longevity.
Yes, we handle all necessary permits and inspections required by Nassau County and local Baldwin Harbor regulations. HVAC installations typically require permits to ensure electrical and mechanical work meets current codes. We’re familiar with local requirements and will pull permits, schedule inspections, and ensure everything passes. This protects you and ensures your installation is compliant with all safety and building standards.
Absolutely. Many Baldwin Harbor homes were built before central air conditioning was standard, so we regularly work with older electrical systems, limited attic space, and existing ductwork challenges. We’re experienced in adapting modern AC systems to older homes while maintaining efficiency and aesthetics. Sometimes this requires creative solutions for ductwork routing or electrical upgrades, which we’ll discuss upfront during our assessment.
Our installation work comes with a comprehensive labor warranty, and your new equipment includes the manufacturer’s parts warranty. We stand behind our workmanship and will address any installation-related issues at no charge during the warranty period. Equipment warranties vary by manufacturer and model, but typically cover parts for several years. We’ll explain exactly what’s covered and help you register your equipment for warranty protection.
Installation costs vary based on system size, equipment type, complexity of installation, and any additional work needed like electrical upgrades or ductwork modifications. We provide detailed written estimates that break down all costs so you know exactly what you’re paying for. There are no hidden fees or surprise charges. We’ll discuss different equipment options and their costs upfront so you can choose what fits your budget and needs.
