Most residential AC installations take 6-8 hours for a complete system replacement. If we’re installing central air for the first time, it might take 1-2 days depending on ductwork requirements. We’ll give you a realistic timeline during our initial assessment. Simple unit swaps where the existing connections work perfectly can sometimes be completed in 4-6 hours. Weather conditions and any unexpected issues with electrical or ductwork can extend the timeline, but we always communicate any delays immediately.
AC size depends on your home’s square footage, insulation, window placement, and ceiling height. A system that’s too small won’t cool effectively, while an oversized unit cycles on and off too frequently, wasting energy and creating humidity problems. We perform detailed load calculations during our assessment, measuring your space and evaluating factors like sun exposure and existing ductwork. Most homes in Pembroke need between 2-5 tons of cooling capacity, but proper sizing requires professional evaluation rather than guesswork.
Yes, existing heating ductwork can often be used for central air conditioning with some modifications. We evaluate your current duct system to ensure it can handle the airflow requirements for cooling. Sometimes we need to add return air ducts or resize certain sections for optimal performance. If your home has radiators or baseboard heating without ducts, we can install a complete ductwork system, though this increases installation time and cost. Mini-split systems are also an excellent option for homes without existing ductwork.
Modern AC units typically require 220-240 volt electrical service, which most homes already have. However, older homes might need electrical upgrades to handle the power requirements safely. We check your electrical panel capacity and existing wiring during our assessment. If upgrades are needed, we coordinate with licensed electricians to ensure everything meets current codes. Most installations only require a dedicated circuit breaker and proper wiring to the outdoor unit. We handle all electrical connections as part of the installation process.
We handle complete removal and proper disposal of your old AC system as part of our installation service. This includes safely recovering refrigerant according to EPA regulations, disconnecting electrical components, and removing both indoor and outdoor units. We dispose of all materials at appropriate recycling facilities – AC units contain metals and refrigerants that require special handling. You don’t need to arrange separate pickup or worry about disposal fees. The removal process is included in your installation cost.
Installation scheduling depends on the season and current demand. During peak summer months, we typically schedule installations within 3-7 days for emergency replacements. Spring and fall installations often happen within 1-3 days of your approval. We keep popular AC units in stock to avoid delays waiting for equipment delivery. If you’re planning ahead for next season, we can often schedule installation within 1-2 days. Emergency situations where your AC has completely failed get priority scheduling, especially during heat waves.
