What does a Drain Alert condensate safety switch do?

It detects condensate backups or pan overflow and opens the safety circuit to shut the system down before water damage occurs.

Where should I install the switch—primary line, secondary pan, or both?

Follow local code and manufacturer instructions. Many installs use a float in the secondary pan plus an inline switch at the primary drain for redundancy.

Is wiring normally open or normally closed?

Most HVAC safety switches are wired in series as normally closed; when water is detected they open the circuit. Verify on the product’s diagram.

Will the switch work with heat pumps and furnaces?

Premium Variable-Speed Comfort - 19 SEER2 Inverter Systems

The 19 SEER2 Inverter category is dedicated to premium variable-speed HVAC systems for projects where top-tier comfort, sound levels, and energy savings matter more than lowest upfront cost. These 19 SEER2 inverter air conditioners and inverter heat pumps are designed for high-performance homes, sensitive spaces, and owners who expect precise temperature control, tight humidity management, and very quiet operation. Inverter compressors ramp capacity up and down in fine steps instead of simply turning on and off, which keeps rooms more stable and reduces energy waste during part-load conditions.

19 SEER2 inverter air conditioners for high-end ducted cooling in primary residences and premium retrofit projects.
19 SEER2 inverter heat pumps delivering efficient heating and cooling with excellent part-load performance and comfort.
Variable-speed compressor technology that modulates capacity instead of cycling on/off at full load.
Low sound ratings and smoother runtimes ideal for bedrooms, offices, and noise-sensitive areas.
Matched indoor coils, air handlers, and communicating controls needed to unlock full system performance and OEM warranty protection.

When you propose 19 SEER2 inverter systems, you are selling a comfort upgrade as much as an efficiency upgrade. These systems shine in markets with high energy costs, long cooling seasons, and owners who notice noise and temperature swings. Use the Compare tools on this page to review capacity, SEER2 / HSPF2 ratings, minimum and maximum operating range, compressor type, refrigerant, and sound data. Make sure the duct design, blower, and controls are compatible so the system can modulate as engineered.

Pro tip: When quoting a 19 SEER2 inverter option, highlight comfort and sound benefits alongside energy savings. Capture model and serial numbers from the existing equipment, plus photos of the air handler, duct connections, and thermostat. Share that information with us and we can help identify compatible inverter systems, required OEM parts, and control strategies so the upgrade runs smoothly from design through commissioning.
