Cover ADU in Fort Worth, CA | Ellery ADU Studio
We’re Ellery ADU Studio, an independent design-build practice that services, repairs, and installs Cover in Arlington and across Fort Worth. We are not a Cover dealer and we don’t answer to a manufacturer’s playbook. What that means for you: when a Cover S Series in a converted garage off Camp Bowie shuts down on a 105°F afternoon, we diagnose the actual failure, use OEM parts where they matter, and tell you plainly when a quality aftermarket component is the better call. Call (971) 497-2402 for service from a team that has worked on these units in Fort Worth’s specific housing stock and climate for years.
Why Fort Worth Residents Choose Us for Cover Service
Cover builds a tight, well-engineered prefab shell, and we respect that. We’ve also spent enough time inside Cover units in Fort Worth to know exactly where the system strains under local conditions: the mini-split fighting 100-degree afternoons, the condensate line choking on cottonwood fluff from the Trinity Park area, the air handler in a converted garage attic cycling harder than it ever would in a coastal climate. Nadia Ellery founded this studio in 2015 and has kept the focus narrow: accessory dwelling units, their permits, their utilities, their HVAC. That’s it. We’re not a general contractor dabbling in ADUs. We’re a team that specifies, services, and repairs Cover systems inside the same single contract we use for the rest of the project. Every job gets a written price before work starts, per Haven Standard Clause 1, and a documented photo record when we’re done.
Common Cover ADU Problems We Solve in Fort Worth

- Condensate drain clogs and overflow shutoffs. Fort Worth’s hard water leaves mineral crust in the drain line, and spring cottonwood from the Trinity River corridor adds a second layer of gunk. The float switch trips, the unit shuts down, and you’re left with a warm ADU. We clear the line, flush it, and often re-route the drain so it’s easier to service next time.
- Compressor contactor pitting from heat-wave cycling. When Fort Worth sits above 100°F for two weeks straight, the contactor opens and closes constantly. The contacts arc, pit, and eventually weld or fail open. We replace contactors with rated components and check the compressor’s amp draw at the same visit so you’re not back in the same spot in August.
- Evaporator coil freeze-ups from Blackland Prairie dust. That fine gray dust from Fort Worth’s expansive clay soil gets through even clean-looking filters. It packs the coil, airflow drops, and the coil ices over. We clean coils, correct airflow, and check refrigerant pressures rather than just telling you to change the filter.
- Failed run capacitors in attic-mounted air handlers. Converted garage ADUs in Fort Worth’s 1950s-1970s ranch neighborhoods frequently put the air handler in a hot attic. Run capacitors hate heat. They fail early up there. We stock the common ratings and swap them on the first visit.
- Undersized mini-splits that never keep up. A Cover unit spec’d for a mild climate gets installed in a Fort Worth garage conversion with a west-facing wall and no shade. The heat load is brutal. We run a proper Manual J load calculation and often find the system is a full half-ton short. That’s a design fix, not a Band-Aid.
Cover Service in Fort Worth: What Local Conditions Mean for Your Equipment
Fort Worth’s Fairmount-Southside Historic District is the clearest example of how local rules reshape Cover work here. The city’s Historic Preservation officer must sign off on any ADU design, and the exterior must match the surrounding 1920s Craftsman bungalows: wood siding, specific rooflines, no modern boxes. But Fort Worth’s zoning also allows a detached ADU to sit closer to the rear property line than most other Texas metros permit. So we frequently design narrow, deep Cover ADUs and New Detached ADU in Fort Worth options that fit those historic setbacks while still giving you real square footage. That’s not a generic brochure answer. That’s what happens when you pull permits for these units in Fort Worth week after week. It also means the mechanical placement matters more: a unit tucked tight to the rear fence has different service clearance than one in the middle of a big suburban lot off the Chisholm Trail Parkway corridor. We plan for that from the first site visit.
Cover Models & Products We Service in Fort Worth

We service the Cover S Series and the Cover C Series. Both lines share a common DNA: panelized shells, efficient envelopes, and a mini-split strategy that is generally solid but demands proper sizing and install. For parts, our rule is simple. If the unit is under warranty or the failing part is central to system performance, we use OEM Cover parts. If you’ve got an older unit and the capacitor or contactor is gone, we’ll tell you when a quality aftermarket component will outlast the original at a lower price. We keep the common failure parts stocked for fast turnaround across Fort Worth, which means we’re not waiting on a distributor in Dallas when your unit is down in July.
Cover Service Pricing in Fort Worth
Service calls in Fort Worth run $95 to $185 for diagnosis, and we credit that toward the repair if you move forward with us. Common fixes like a capacitor or contactor replacement land between $180 and $340 including parts and labor. A full evaporator coil clean on our Garage Conversion ADU in Fort Worth typically runs $250 to $450 depending on access. Compressor replacement on an out-of-warranty Cover S Series: $1,800 to $2,900 all-in, which is why we always lay out repair versus replace numbers side by side before any work begins. Your free estimate covers the diagnosis, the written scope, and the exact line-item price. Call (971) 497-2402 and we’ll put it on paper before anything gets unscrewed.

FAQs - Cover ADU in Fort Worth
In most Fort Worth homes we see, it’s the condensate line or the contactor. Hard water scale plus cottonwood fluff clogs the drain and trips the float switch, or months of heat-wave cycling pit the contactor until it fails. We test both on the first visit and fix them the same day in most cases. Call (971) 497-2402 for an exact diagnosis, free with your estimate.
Yes. Everything we do inside the building envelope, like servicing the mini-split, replacing a compressor, or re-running a condensate line, does not touch the exterior and does not go in front of the Historic Preservation officer. Any exterior change, including a mechanical penetration or a new condenser location visible from the street, does require design review. We’ll tell you which is which before you file anything.
In Fort Worth, that’s usually Blackland Prairie dust packed into the evaporator coil. The filter catches the big stuff but the fine clay particles get through and choke airflow until the coil ices. We clean the coil and check refrigerant charge, because a slightly low charge compounds the same symptom. Call (971) 497-2402 and we’ll get it sorted.
Often, yes. Fort Worth’s mid-century ranch stock frequently still has 100-amp panels, and a Cover ADU with a mini-split, water heater, and kitchen loads can push that past safe capacity. We’ll have an electrician assess the panel during the free estimate and include any upgrade in the written scope, so there’s no surprise line item later.
If the compressor is fine, repair is almost always the right call. A capacitor, contactor, or coil clean costs a few hundred dollars and buys real years. If the compressor is dead, you’re looking at $1,800 to $2,900 to rebuild what’s still a decade-old system. We’ll show you both numbers and let you decide. Call (971) 497-2402 for a written breakdown.
