AC Installation Service Process

Straightforward Installation, Zero Surprises

First, we assess your home’s cooling needs with proper load calculations. This isn’t guesswork – we measure square footage, insulation levels, window placement, and existing ductwork to determine exactly what size system you need.

Next comes equipment selection. We’ll explain your options for energy efficiency, features, and warranty coverage so you can make an informed decision that fits your budget and cooling requirements.

Installation day starts with protecting your floors and furniture. Our team removes your old system, installs the new equipment, connects all electrical and refrigerant lines, and tests everything thoroughly. We clean up completely before leaving and walk you through your new system’s operation.

Most AC installations in Plympton take 6-8 hours for a complete system replacement. This includes removing your old equipment, installing the new indoor and outdoor units, connecting refrigerant lines, and testing everything thoroughly. If your home needs electrical upgrades or ductwork modifications, add another 2-4 hours. Our team works efficiently while maintaining quality standards – we’re not rushing through your installation just to get to the next job. Weather can affect timing slightly, but we’ll give you a realistic timeframe upfront and keep you updated throughout the day.
AC sizing depends on your home’s square footage, insulation quality, window placement, ceiling height, and local climate conditions. A proper load calculation is essential – too small and your system runs constantly without reaching comfortable temperatures, too large and it cycles on and off frequently without removing humidity effectively. Most Plympton homes need between 2-5 tons of cooling capacity. Our team performs detailed measurements and calculations rather than guessing based on your old system size, because that old system might have been incorrectly sized from the start.
Yes, there are several options for homes without existing ductwork in Plympton. Ductless mini-split systems are popular because they don’t require extensive ductwork installation and offer zone-by-zone temperature control. For whole-house cooling, new ductwork can be installed through basements, crawl spaces, or attics depending on your home’s layout. High-velocity systems use smaller ducts that fit in tight spaces where traditional ductwork won’t work. The best solution depends on your home’s construction, your cooling preferences, and your budget. We’ll assess your specific situation and explain all viable options.
Modern AC systems are significantly more energy-efficient than units installed even 10 years ago. If you’re replacing an older system, you’ll likely see lower energy bills despite having reliable cooling. New systems with high SEER ratings use 20-40% less electricity than older units. Your actual costs depend on how much you use the system, your home’s insulation, and local electricity rates. Proper installation and sizing are crucial – an incorrectly installed system wastes energy regardless of its efficiency rating. We’ll help you understand the energy costs based on your specific equipment choice and usage patterns.
New AC installations come with manufacturer warranties on equipment and workmanship warranties on installation. Most equipment warranties cover parts for 5-10 years, with some components covered longer. Installation workmanship is typically warranted for 1-2 years. Dempsey Energy’s service team handles warranty claims and repairs, so you’re not dealing with multiple companies if issues arise. Our Dempsey Comfort Club members get priority service scheduling. Most problems with new installations are minor and easily resolved – issues like thermostat programming, airflow adjustments, or refrigerant fine-tuning that don’t indicate major system problems.
Spring and early summer offer the best scheduling flexibility and sometimes better equipment pricing, but AC installation is needed year-round in Massachusetts. If your system fails during peak summer, don’t wait – heat waves can be dangerous, especially for elderly family members or those with health conditions. Emergency installation is available when needed. Fall and winter installations are possible and often have shorter wait times, though you won’t know how well the system performs until the following summer. The key is not waiting until your old system completely fails, because that’s usually when you need cooling most urgently.
