How We Handle Your Installation

The process starts with properly sizing your system based on your home’s actual cooling needs, not just square footage. This prevents the energy waste and comfort problems that come with oversized units.

Installation day involves careful handling of your existing ductwork, proper refrigerant line installation, and electrical connections that meet code requirements. Our team protects your home during the work and cleans up completely when finished.

After installation, we test the entire system to verify proper operation and walk you through basic maintenance. You get documentation for warranty purposes and information about ongoing service through the Dempsey Comfort Club if you’re interested.

Most residential AC installations take 6-8 hours for a simple replacement but can extend to a full day or more if ductwork modifications are needed. The timeline depends on your home’s existing setup, accessibility, and whether you’re upgrading from an older system that requires electrical updates. We provide realistic timeframes upfront so you can plan accordingly. We focus on doing the job right rather than rushing through installation, because proper installation prevents the callbacks and problems that waste everyone’s time later.
AC sizing depends on factors beyond just square footage, including ceiling height, insulation quality, window placement, and local climate conditions. A proper load calculation considers heat gain from windows, appliances, and occupancy patterns to determine the right capacity. Oversized units cycle on and off too frequently, wasting energy and failing to remove humidity properly. Undersized units run constantly without achieving comfortable temperatures. Professional sizing confirms your system runs efficiently and maintains consistent comfort throughout your Braintree home during peak summer conditions.
Ductwork replacement isn’t always necessary, but it should be evaluated during AC installation. If your existing ducts are properly sized, sealed, and in good condition, they can often be used with a new system. However, leaky or undersized ductwork can reduce efficiency by 20-30% and create comfort problems regardless of how good your new AC unit is. We assess ductwork condition and sizing as part of the installation process, recommending modifications only when they’ll meaningfully improve performance and comfort in your home.
AC replacement typically makes sense when repair costs exceed 50% of a new system’s value or when your unit is over 10-12 years old and requiring frequent repairs. Constantly rising energy bills, uneven cooling, and inability to maintain comfortable temperatures are signs your system is struggling. If you’re calling for repairs multiple times per season, replacement often provides better value than continuing to fix an aging system. A professional assessment can help you understand whether your current system has useful life remaining or if replacement will save money long-term.
New AC systems need regular filter changes every 1–3 months, depending on usage and filter type, annual professional tune-ups, and basic upkeep like keeping the outdoor unit clear of debris. Professional maintenance includes checking refrigerant levels, cleaning coils, inspecting electrical connections, and testing system performance. Proper maintenance extends system life, maintains efficiency, and prevents small problems from becoming expensive repairs. Our Comfort Club membership program provides scheduled maintenance to keep your investment protected and running efficiently throughout its lifespan.
Ductless systems work particularly well in older homes that lack existing ductwork or have ductwork that’s difficult to access or modify. These systems provide zone control, allowing you to cool specific areas without the energy loss associated with long duct runs. Installation is less invasive than central air, requiring only small holes for refrigerant lines between indoor and outdoor units. Ductless systems can supplement existing heating systems or provide complete cooling solutions. They’re especially effective for additions, converted spaces, or homes where traditional ductwork installation would be extremely disruptive or expensive.
