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?

Yes—wire it into the low-voltage safety circuit per the unit’s control board diagram.

Do I need maintenance after installation?

Keep drains clear, test the float at service visits, and replace the switch if it shows wear or fails a function test.

Complete Systems & Replacement Units — HVAC Equipment

Build and replace comfort systems with HVAC equipment selected for real residential and light-commercial jobs. This section focuses on complete heating and cooling systems rather than small replacement parts, so you can plan full system changeouts, new installs, and major upgrades from one place. From central air systems and heat pumps to ductless mini-splits, packaged units, and PTAC / VTAC equipment, you’ll find options sized for typical homes and light-commercial spaces across the U.S., supported from our Doral, Florida base.

Central air systems for straight-cool and gas furnace split systems when you need traditional, ducted comfort with proven reliability.
Heat pumps (1.5–5 ton) for all-electric or dual-fuel applications where higher efficiency and lower operating costs are a priority.
Ductless mini-split equipment for additions, bonus rooms, garages, and other areas where running full ductwork isn’t practical.
Packaged units and rooftops that combine heating and cooling in a single cabinet for small commercial buildings and tight mechanical rooms.
PTAC / VTAC units tailored to hotels, multifamily properties, senior housing, and hospitality projects that need in-room control and fast replacement.

Every job starts with proper sizing and application. Use your load calculations, existing model numbers, and project details to narrow down the HVAC equipment that fits the building, ductwork, and local code requirements. Once you’ve identified the right system type, the Compare section and detailed product filters on this page help you drill into capacities, voltages, configurations, and efficiency ratings.

Pro tip: When you’re planning a system changeout, snap photos of the nameplates for both indoor and outdoor units and save them with your notes. Share those model numbers with us and we can help confirm compatible HVAC equipment and point you toward matching OEM parts if you’re also updating coils, motors, or controls on the same job.
