When homeowners want to upgrade to more efficient HVACR systems, complex wiring requirements often become an unwelcome roadblock. tekmar built the Invita 564 specifically to remove these barriers for contractors, allowing them to say yes to jobs they’d typically have to decline or quote at much higher prices.
“Partnering with ACCA keeps us grounded in what matters—supporting contractors with solutions that simplify installs and expand what’s possible in the field,” says Mercedeh Fallahkhair, Senior Product Manager at Tekmar
Customers don’t understand why a thermostat requires tearing open walls
The Invita 564 is installed using existing two-wire connections in homes where conventional smart thermostats simply won’t work without extensive modifications. This eliminates the most common thermostat installation headaches: pulling new wires, patching walls, dealing with unreliable power stealing, weak wireless signals, and constant battery replacements.
One contractor’s experience highlights the difference. When replacing a furnace with a heat pump in an older home with minimal thermostat wiring, the technician faced what would typically require wall damage and additional electrical work. With the Invita 564, the installation took under an hour instead. No rewiring, no return visits, no explaining unexpected costs to the customer.
Every truck only has so much space for inventory
Carrying multiple thermostat models for different wiring scenarios takes valuable truck space and mental bandwidth. The Invita 564 works with nearly all HVACR systems—including forced air, heat pumps, and dual fuel configurations—so contractors need fewer specialized options on hand.
This versatility makes it particularly valuable for hybrid systems and furnace-to-heat-pump conversions, situations where standard thermostats often fall short. When contractors can quickly replace older systems with energy-efficient options regardless of wiring limitations, they avoid the delays and customer frustrations that typically accompany these jobs.
Every hour spent rewiring is an hour not spent making money
The business math is straightforward: contractors who spend less time on wiring complications complete more jobs. Those who make fewer return visits for troubleshooting have more time for new installations.
tekmar consistently hears from contractors that the Invita helps them deliver energy-efficient solutions to customers who thought their home’s wiring made upgrades impossible. When homes with old wiring, mixed systems, or difficult retrofit situations become opportunities instead of problems, contractors sell more with less effort.
Designing for contractors means understanding their daily challenges
tekmar designs with a clear priority: fix what frustrates contractors first, then add features homeowners want. This creates products that work on real job sites, not just in showrooms.
The Invita 564 wasn’t built to win design competitions. It was built to help HVACR professionals make money on jobs they’d otherwise decline. By addressing one of the industry’s biggest installation barriers—limited wiring—tekmar gives contractors a tool that expands what they can offer customers.
As tekmar continues developing products for retrofit challenges, they remain focused on solutions that reduce installation time, improve system compatibility, and help contractors grow by saying yes when they’d normally say no.
