Tech Tips:

Our HVAC equipment can’t run without the contactor coil, but contactors can develop problems with age and during high-voltage electrical events. Contact pitting is unmistakable, and it’s unfortunately all too common in areas where bugs can get into the coil and fry on the contacts. Factor in problems with the utility, such as brownouts and […]

Crankcase Heaters and Single-Pole Contactors

We keep two-pole, 40-amp 24v coil contactors on all of our vans. They are versatile and reliable, and you can replace most residential A/C contactors with them.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this short episode of the HVAC School podcast, Bryan and Tom Lorenz from Copeland talk about the new Sensi equipment interface. This product has been in field trials for months and will be launching in February. It will also be featured at the 2025 AHR Expo in Orlando. You can learn more about when and where the product launch will be at AHR at https://ahr25.mapyourshow.com/8_0/sessions/session-details.cfm?scheduleid=197.

Sensi is launching the new Sensi equipment interface module (indoor and outdoor), which eliminates the need to pull additional thermostat wire, and it’s great for upgrades from A/C units to heat pumps or single-stage or multi-stage units. These have a strong wireless connection that can be picked up approximately 100 feet through walls.

The ideal indoor application will be whenever you have single-stage to multi-stage upgrades and can’t pull more wires. Outdoor applications are best for A/C-to-heat pump conversions and upgrades from single-stage to multi-stage. This module also contains outdoor sensors and can work with accessories like dehumidifiers. The Sensi equipment interface module has been tested in extreme weather conditions and has proven its durability.

These will be launched as part of a kit with indoor and outdoor modules and a Sensi Touch 2 smart thermostat. The Sensi Touch 2 will also receive an upgrade to make it compatible with the new Sensi equipment interface module. The Sensi equipment interface module will also come with contractor branding capabilities, which is an option for Sensi smart thermostats and traditional White-Rodgers thermostats.
