</section> 
<section class="dwc-outer"> <div class="dwc-layout"> <main class="dwc-prose" id="dwc-article-top"> <p>A ductless system in a Wildwood Crest home had reached the end of its life &mdash; three indoor units (one ducted into the attic, two wall-mounted) all running off a single aging outdoor condenser. The whole system needed to come out and be replaced, not patched.</p> <p>Budd&rsquo;s installed a new <a href="/ductless-hvac-systems">Fujitsu Airstage ductless system</a> in its place: a new outdoor unit, a ducted unit in the attic, and two wall-mounted heads, each one controllable on its own through the Fujitsu Airstage app. Here&rsquo;s what the job actually involved, including the parts that didn&rsquo;t go according to plan.</p> <div class="dwc-spec-list"> <span class="dwc-spec-list__title">Equipment Installed</span> <ul> <li><strong>Outdoor unit:</strong> Fujitsu AOUH45KWAS</li> <li><strong>Ducted indoor unit:</strong> 18,000 BTU, installed in the attic</li> <li><strong>Wall-mounted head:</strong> 12,000 BTU, bedroom</li> <li><strong>Wall-mounted head:</strong> 7,000 BTU, living room</li> <li><strong>Controls:</strong> Wi-Fi module on each indoor unit for independent control through the Fujitsu Airstage mobile app</li> </ul> </div> <h2 id="scope-of-work">Removing the Old System and Setting the New Outdoor Unit</h2> <p>The job started with demo &mdash; pulling all three old indoor units and the old outdoor condenser out of the home and clearing the space for the new equipment. Once the old outdoor unit was out, the crew set the pad and positioned the new outdoor unit in its place.</p> <p>With the outdoor unit set, the crew removed the old attic ducted unit and mounted the two new wall heads &mdash; one in the bedroom, one in the living room. Running refrigerant lines from the outdoor unit to each indoor head meant cutting new access holes on the first floor to route the line sets up through the house.</p> <h2 id="attic-ductwork">Rebuilding the Attic Ductwork</h2> <p>An 18,000 BTU ducted unit doesn&rsquo;t always work with whatever ductwork was left behind by the system it&rsquo;s replacing &mdash; and that&rsquo;s what turned up in the attic here. Once the old attic unit was out, it was clear the existing ductwork wasn&rsquo;t going to support the new equipment.</p> <p>Instead of forcing the new unit onto ductwork it wasn&rsquo;t sized for, the crew fabricated and built new ductwork on-site, wrapped (insulated) the supply run, and modified the attic space so the new ducted unit would actually fit and perform the way it&rsquo;s supposed to. That&rsquo;s not a step every ductless replacement needs &mdash; it depends entirely on what the existing ductwork can support &mdash; but it&rsquo;s the kind of thing that turns a straightforward swap into a longer job.</p> </main>  <aside class="dwc-sidebar"> <div class="dwc-toc"> <p class="dwc-toc__label">In This Article</p> <nav aria-label="Article contents"> <a href="#scope-of-work">Removing the Old System</a> <a href="#attic-ductwork">Rebuilding the Attic Ductwork</a> <a href="#mid-install-issues">What Came Up Mid-Install</a> <a href="#programming-app-control">Programming &amp; App Control</a> <a href="#the-result">The Result</a> </nav> </div> <div class="dwc-service-card"> <h3>Ductless system due for an upgrade?</h3> <p>We install and service Fujitsu, Samsung, and Gree ductless systems throughout Cape May County and Atlantic County, NJ.</p> <a href="https://www.buddsplumbing.com/contact-us">Request Service</a> </div> <div class="dwc-phone-card"> <span class="dwc-phone-card__label">Call us directly</span> <a href="tel:+16094653759">(609) 465-3759</a> </div> </aside> </div>

<section class="dwc-outer"> <div class="dwc-layout"> <div class="dwc-prose" id="dwc-article-lower"> <h2 id="mid-install-issues">What Came Up Mid-Install: A Storm, an Undersized Drain Line, and a Refrigerant Leak</h2> <p>Not every job wraps up in a single visit, and this one didn&rsquo;t. Three separate issues turned up near the end of the first day&rsquo;s work:</p> <ul> <li>A thunderstorm knocked out power at the house, which took the customer&rsquo;s home Wi-Fi down with it &mdash; with no network available, there was no way to get the new Wi-Fi control modules connected and configured that night.</li> <li>The existing condensate drain line was undersized for the new system. The Fujitsu ducted unit calls for 3/4&Prime; PVC; what was already in place wasn&rsquo;t up to that spec. The crew rerouted and replaced the drain line with proper 3/4&Prime; PVC running out to the gutter drain point.</li> <li>One of the newly installed line sets developed a leak at a flare fitting after the system was pulled down to vacuum and the refrigerant was released into the lines. Rather than charge a system with a known leak, the crew cut out the affected section of line set, replaced the flare fitting, and restarted the evacuation process from scratch.</li> </ul> <div class="dwc-callout"> <p>None of that is unusual for a full system replacement on an older home &mdash; it&rsquo;s exactly why a proper vacuum-and-leak-check happens before a system gets its final refrigerant charge. Finding a leak at this stage means it gets fixed before the system is ever running, not after.</p> </div> <p>Between the storm and the leak repair, the crew couldn&rsquo;t finish programming the ducted unit that evening, so the job carried over to a second visit.</p> <h2 id="programming-app-control">Finishing the Job: Programming and Independent Room Control</h2> <p>On the return visit, the crew finished setting up and programming the ducted unit&rsquo;s control settings. The system is fully operational &mdash; all three zones (attic-ducted, bedroom, living room) heating and cooling on their own, with no shared settings between rooms.</p> <p>The one piece still pending at the end of the job was the Wi-Fi connection. The new Wi-Fi modules are installed and ready to go, but the home&rsquo;s router was broadcasting a combined 2.4GHz/5GHz signal, and the Fujitsu Wi-Fi modules only connect to a 2.4GHz network. Once the homeowner splits her router into separate 2.4GHz and 5GHz networks &mdash; a setting most routers have, though it&rsquo;s sometimes buried in the admin panel &mdash; connecting the modules and pairing the Fujitsu Airstage app takes a few minutes.</p> <h2 id="the-result">The Result</h2> <p>The homeowner now has three independently controlled comfort zones in a home that previously ran off a single aging ductless system &mdash; heating and cooling in the attic-ducted space, the bedroom, and the living room, each one adjustable on its own through the Fujitsu Airstage app once the Wi-Fi step is finished on her end.</p> <figure class="dwc-article-img-wrap"> <img src="https://cdn.prod.website-files.com/650cd965726009dccb50a827/6a68d15b1666d83f0e6e5343_aircon-indoor-unit.png" alt="Newly installed Fujitsu Airstage indoor unit in a Wildwood Crest, NJ home, fully operational after the ductless system replacement"> <figcaption>One of the new Fujitsu Airstage indoor units, installed and fully operational.</figcaption> </figure> <p>If your home&rsquo;s ductless system is aging, mismatched to your ductwork, or you&rsquo;re considering a switch to independent zone control, Budd&rsquo;s installs and services <a href="/ductless-hvac-systems">ductless mini-split systems</a> throughout Cape May County and Atlantic County, including Wildwood Crest, Wildwood, and Avalon.</p> <div class="dwc-inline-cta"> <a href="https://www.buddsplumbing.com/contact-us">Schedule a Ductless System Evaluation &rarr;</a> </div> </div>  <div class="dwc-sidebar-spacer" aria-hidden="true"></div> </div>

Ducted mini-split units are sized to specific airflow and duct requirements, and ductwork built for a different system doesn&rsquo;t always match up with new equipment. If the existing ductwork can&rsquo;t support the new unit, it needs to be rebuilt or modified as part of the installation &mdash; that&rsquo;s a normal part of some ductless replacements, not a sign anything went wrong.</p> </div> </div> <div class="dwc-faq-item"> <button class="dwc-faq-btn" aria-expanded="false" aria-controls="dwc-faq-answer-2" id="dwc-faq-btn-2"> What size drain line does a ductless mini-split system need? </button> <div class="dwc-faq-answer" id="dwc-faq-answer-2" role="region" aria-labelledby="dwc-faq-btn-2"> <p>It depends on the manufacturer and system, but many ducted mini-split units require a minimum 3/4&Prime; PVC condensate drain line. An undersized drain line can back up or leak, so it&rsquo;s worth checking during any ductless installation or replacement rather than assuming the existing line is adequate.</p> </div> </div> <div class="dwc-faq-item"> <button class="dwc-faq-btn" aria-expanded="false" aria-controls="dwc-faq-answer-3" id="dwc-faq-btn-3"> Can each room on a ductless system be controlled separately? </button> <div class="dwc-faq-answer" id="dwc-faq-answer-3" role="region" aria-labelledby="dwc-faq-btn-3"> <p>Yes &mdash; that&rsquo;s one of the main advantages of a multi-zone ductless system. Each indoor head or ducted unit can run its own temperature and schedule, and with Wi-Fi modules installed, each zone can be controlled independently through a mobile app instead of one shared thermostat for the whole system.</p> </div> </div> <div class="dwc-faq-item"> <button class="dwc-faq-btn" aria-expanded="false" aria-controls="dwc-faq-answer-4" id="dwc-faq-btn-4"> Why won&rsquo;t my mini-split&rsquo;s Wi-Fi module connect to my home network? </button> <div class="dwc-faq-answer" id="dwc-faq-answer-4" role="region" aria-labelledby="dwc-faq-btn-4"> <p>Most ductless system Wi-Fi modules, including Fujitsu&rsquo;s, only connect to a 2.4GHz network. If your router broadcasts a single combined 2.4GHz/5GHz signal, the Wi-Fi module may not be able to find or connect to it. Splitting your router into separate 2.4GHz and 5GHz networks in the router&rsquo;s settings usually resolves it.</p> </div> </div> </div>

Ducted mini-split units are sized to specific airflow and duct requirements, and ductwork built for a different system doesn't always match up with new equipment.

An undersized drain line can back up or leak, so it's worth checking during any ductless installation or replacement rather than assuming the existing line is adequate." } }, { "@type": "Question", "name": "Can each room on a ductless system be controlled separately?", "acceptedAnswer": { "@type": "Answer", "text": "Yes — that's one of the main advantages of a multi-zone ductless system. Each indoor head or ducted unit can run its own temperature and schedule, and with Wi-Fi modules installed, each zone can be controlled independently through a mobile app instead of one shared thermostat for the whole system." } }, { "@type": "Question", "name": "Why won't my mini-split's Wi-Fi module connect to my home network?", "acceptedAnswer": { "@type": "Answer", "text": "Most ductless system Wi-Fi modules, including Fujitsu's, only connect to a 2.4GHz network. If your router broadcasts a single combined 2.4GHz/5GHz signal, the Wi-Fi module may not be able to find or connect to it. Splitting your router into separate 2.4GHz and 5GHz networks in the router's settings usually resolves it." } } ] } ]
