Most importantly, you get peace of mind. No wondering if corners were cut or if you’ll face expensive repairs because someone rushed through the job.

Here's How We Handle Your Installation

First, we assess your home’s cooling needs and existing infrastructure. This means measuring spaces, checking electrical capacity, and evaluating ductwork. No guesswork on sizing because an oversized unit wastes energy and an undersized one never keeps up.

Next, we handle permits and schedule the installation around your availability. Our crew arrives with the right equipment and materials to complete the job without multiple trips to the supply house.

Installation day involves careful placement of both indoor and outdoor units, proper refrigerant line connections, electrical hookups, and thorough testing. We clean up completely and walk you through operation and maintenance basics before we leave.

Most residential AC installations take between 6-8 hours for a straightforward replacement where existing ductwork and electrical are adequate. If we’re installing central air for the first time or need to upgrade electrical panels or add ductwork, it can take 1-2 days. We’ll give you a realistic timeline during our initial assessment so you can plan accordingly. Weather delays are rare since most of our work happens indoors, but we’ll communicate immediately if anything changes your scheduled completion time.
AC sizing depends on your home’s square footage, insulation levels, window placement, ceiling height, and local climate factors. We perform Manual J load calculations to determine the exact cooling capacity needed. Most Walpole homes need between 2-5 tons of cooling capacity, but guessing wrong costs you money either way. An oversized unit cycles on and off too frequently, wasting energy and failing to remove humidity properly. An undersized unit runs constantly and never reaches your desired temperature, especially during peak summer heat.
Yes, Walpole requires permits for air conditioning installation, especially when electrical work is involved or when installing new systems. We handle all permit applications and coordinate required inspections with the local building department. This protects you by ensuring the work meets current codes and maintains your home insurance coverage. Some homeowners try to skip permits to save money, but it creates problems when selling the house or filing insurance claims later.
Absolutely. We install both central air systems with new ductwork and ductless mini-split systems depending on your home’s layout and your preferences. Ductless systems work well in older homes because they don’t require major renovations or space for large ducts. Central air with new ductwork provides whole-house cooling but involves more extensive installation. We’ll evaluate your home’s structure, available space, and budget to recommend the best approach for your specific situation.
Many older homes need electrical upgrades to safely power modern air conditioning systems. We coordinate with licensed electricians to upgrade panels or add dedicated circuits when necessary. This is common in Norfolk County homes built before central air was standard. The electrical upgrade typically adds 1-2 days to the project timeline and additional cost, but it’s essential for safe operation. We identify electrical limitations during our initial assessment so there are no surprises on installation day.
Change your air filter every 1-3 months depending on usage and filter type. Keep the outdoor unit clear of debris, leaves, and vegetation that can restrict airflow. Schedule annual professional maintenance to check refrigerant levels, clean coils, and catch small issues before they become expensive repairs. Our Dempsey Comfort Club membership includes priority scheduling for maintenance visits and discounts on repairs. Most manufacturer warranties also require proof of annual maintenance to remain valid, so regular service protects your investment.
