Your new air conditioner runs efficiently because every connection, every duct, and every component was installed to manufacturer specifications.

The difference shows up in your monthly utility bills and in how your home feels during those humid Massachusetts summers. You’re not just buying equipment – you’re investing in reliable comfort that lasts.

AC Installation Process

Here's Exactly What Happens

First, our technician evaluates your home to determine the right system size and placement. This isn’t guesswork – we calculate your cooling needs based on square footage, insulation, windows, and local climate factors.

Next, we handle permits and coordinate the installation timeline that works with your schedule. On installation day, our team removes your old system (if applicable), installs the new equipment, connects all electrical and refrigerant lines, and tests everything to ensure proper operation.

Before we leave, we walk you through your new system’s operation and maintenance requirements. You get documentation for warranties and service records, plus information about the Dempsey Comfort Club for ongoing maintenance that keeps your investment protected.

AC Replacement and Installation

What's Included in Professional Installation

Professional AC installation means more than just connecting equipment. Our team handles load calculations to ensure your system is properly sized – not too big, not too small, but exactly right for your home’s cooling needs.

Installation includes all electrical connections, refrigerant lines, condensate drainage, and ductwork modifications if needed. We pull necessary permits, coordinate inspections, and ensure everything meets local codes before considering the job complete.

You also get startup and testing of the complete system, plus a walkthrough of operation and maintenance. Many Marshfield Hills homes have unique considerations – from coastal humidity to older electrical systems – and our experienced local technicians know how to handle these challenges properly.

Most residential AC installations take 6-8 hours for a straightforward replacement, or a full day for new installations requiring additional electrical or ductwork. The timeline depends on your home’s specific requirements – older homes sometimes need electrical upgrades, while new construction might need complete ductwork installation. During your initial consultation, our technician will give you a realistic timeframe based on your situation. Emergency replacements can often be completed the same day if you’re dealing with a complete system failure during peak summer weather.
System sizing depends on several factors specific to your home: square footage, ceiling height, insulation quality, window placement, and local climate conditions. A professional load calculation determines the exact BTU requirements – this isn’t something you want to guess at. Oversized systems cycle on and off too frequently, wasting energy and failing to remove humidity properly. Undersized systems run constantly without adequately cooling your home. Massachusetts homes, especially in coastal areas like Marshfield Hills, have unique humidity considerations that affect sizing calculations. Our technician measures and calculates rather than estimating.
Yes, most AC installations in Massachusetts require permits, especially for new installations or major replacements involving electrical work. Local building codes in Bristol County have specific requirements for HVAC installations, electrical connections, and refrigerant handling. We handle permit applications and coordinate required inspections as part of the installation process. Attempting installation without proper permits can create problems with home insurance, future sales, and local code enforcement. Working with licensed contractors ensures all permit and inspection requirements are met properly.
If your system is over 10-12 years old and requiring frequent repairs, replacement usually makes more financial sense than continuing to fix an aging system. Other signs include dramatically increased energy bills, uneven cooling throughout your home, or repairs that cost more than half the price of a new system. Systems that use R-22 refrigerant (being phased out) often make better candidates for replacement since refrigerant costs have increased significantly. We can assess your current system’s condition and help you make an informed decision based on repair costs versus replacement benefits.
Central air systems use ductwork to distribute cool air throughout your home and work well for whole-house cooling. Ductless mini-split systems cool individual rooms or zones without requiring ducts, making them ideal for additions or homes without existing ductwork. Heat pumps provide both heating and cooling, which can be efficient in Massachusetts’ moderate climate. Window units cool single rooms but aren’t practical for whole-house comfort. The best choice depends on your home’s layout, existing infrastructure, and cooling needs. We can assess your situation to determine which system type matches your specific needs.
Regular maintenance keeps your new AC system running efficiently and extends its lifespan significantly. This includes changing air filters monthly during peak usage, keeping outdoor units clear of debris, and scheduling annual professional tune-ups before cooling season begins. Professional maintenance includes cleaning coils, checking refrigerant levels, testing electrical connections, and identifying potential issues before they become expensive problems. Many homeowners join service programs like the Dempsey Comfort Club to ensure consistent maintenance scheduling. Proper maintenance can extend system life by several years and maintains energy efficiency throughout the equipment’s lifespan.
