What Proper Installation Actually Gets You

When your AC is installed correctly, you notice the difference immediately. Even temperatures throughout every room. Lower energy bills because the system isn’t working overtime to compensate for poor installation. Quiet operation that doesn’t wake you up at night.

You get years of reliable cooling instead of constant service calls. Your system lasts longer because it’s not straining against improper sizing or faulty connections. Most importantly, you have confidence that when the next heat wave hits Lakeville, your home stays comfortable.

The right installation means your investment pays off for years, not months. You’re not dealing with hot spots, humidity problems, or that sinking feeling when the system struggles on the hottest days.

How We Handle Your Installation

Next, we provide a clear recommendation based on your home’s requirements, not our profit margins. We explain what size system you need, why, and what the installation involves. No surprises, no pressure.

On installation day, our team arrives with everything needed to complete the job. We protect your floors and furniture, install your new system properly, and test everything thoroughly before we leave. You get a walkthrough of your new system and clear information about maintenance and warranties.

What's Included in Professional Installation

Professional AC installation means more than just connecting equipment. We perform load calculations to determine the right system size for your home’s square footage, insulation, and layout. Undersized systems run constantly and never cool properly. Oversized systems cycle on and off, wasting energy and creating humidity problems.

We handle all electrical connections, refrigerant lines, and ductwork modifications needed for optimal performance. Our installations include proper drainage, secure mounting, and thorough testing of all system components. You receive manufacturer warranties plus our commitment to address any installation-related issues.

For Lakeville homeowners, we understand the importance of systems that handle our humid summers efficiently. That means proper refrigerant charging, sealed ductwork, and electrical connections that won’t fail when you need cooling most. Our Dempsey Comfort Club members get ongoing maintenance to keep their investment running smoothly year after year.

Most residential AC installations take 6-8 hours for a straightforward replacement, or 1-2 days for new installations requiring electrical work or ductwork modifications. Lakeville’s mix of newer and older homes means installation time varies based on your specific situation. Older homes often need electrical upgrades or ductwork adjustments that add time but ensure safe, proper operation. We provide realistic timeframes upfront so you can plan accordingly. Weather delays are rare since most installation work happens indoors, but we’ll communicate any schedule changes immediately.
System sizing depends on your home’s square footage, insulation levels, window placement, and ceiling height – not just square footage alone. Most Lakeville homes need between 2-5 tons of cooling capacity, but we perform detailed load calculations to determine your exact requirements. Factors like sun exposure, number of occupants, and existing ductwork all affect sizing. An oversized system wastes energy and doesn’t remove humidity properly. An undersized system runs constantly and never achieves comfortable temperatures. We measure and calculate rather than guess, ensuring your system matches your home’s actual cooling needs.
Yes, we obtain necessary permits and coordinate required inspections for AC installations in Lakeville and throughout Bristol County. Most AC replacements need electrical permits, especially if we’re upgrading electrical service to handle modern, more efficient systems. New installations typically require both electrical and mechanical permits. We handle the paperwork, scheduling, and inspector coordination so you don’t have to navigate town requirements. Our familiarity with local codes and inspector preferences helps avoid delays and ensures your installation meets all safety and efficiency standards from the start.
Absolutely. We install both central air systems with new ductwork and ductless mini-split systems depending on your home’s layout and your preferences. For homes without existing ducts, we evaluate whether traditional ducted systems or ductless options work better. Ductless systems often make sense for older Lakeville homes where adding ductwork would be disruptive or impractical. Central systems work well when we can run ducts through basements, attics, or crawl spaces. We explain both options, including long-term costs and performance differences, so you can make the right choice for your situation and budget.
All our installations come with manufacturer warranties on equipment plus our guarantee on installation workmanship. If you experience problems related to our installation work, we return to address them at no charge. Most issues in the first year stem from installation problems, not equipment defects, which is why proper installation matters so much. Our Dempsey Comfort Club members get priority service and regular maintenance to prevent problems before they start. We maintain detailed records of every installation, so if you need service months or years later, we know exactly what was installed and how your system is configured.
Installation costs vary based on system size, equipment efficiency, and installation complexity. Straightforward replacements typically cost less than new installations requiring electrical upgrades or ductwork. Higher-efficiency systems cost more upfront but reduce monthly energy bills significantly over time. We provide detailed estimates that break down equipment and labor costs clearly, so you understand exactly what you’re paying for. Rather than give you a range that might not apply to your situation, we prefer to assess your specific needs and provide accurate numbers. Our estimates include everything needed to complete the job properly – no surprise charges later.
