Thermostats and Temperature Control Systems  

Explore temperature control options that let you schedule, automate and monitor temperatures at home or on the go, and choose controls that match your HVAC system for reliable performance.

Thermostats

Dial in comfort and efficiency with the right thermostat. Choose from simple non-programmable models, programmable options for set-and-forget schedules or smart Wi‑Fi thermostats you can control from your phone. Look for compatibility with your system and helpful features like room sensors, geofencing and energy-use insights.

HVAC Controls

Behind the scenes, HVAC controls coordinate how your system heats and circulates air. Zone controls help direct heat where you need it, while relays, fan or limit controls and control boards manage blowers and burners for safer, more reliable performance. Replacing a worn control with the correct spec can restore consistent operation and improve comfort.

Temperature Alarm Systems

Temperature and freeze alarms add peace of mind for basements, garages and vacation homes. Choose plug-in or battery-powered units with audible alerts, or Wi‑Fi smart monitors that send notifications if temps drop too low or rise too high. Many models track humidity, too, so you can spot issues early and protect pipes, pets and stored items.

Heating System Components and Replacement Parts

Keep essential parts on hand to solve common heating issues fast.

Igniters

If your gas furnace won’t light, the hot surface igniter may be due for replacement. Match the shape, connector and voltage to your model for proper fit. Ceramic and silicon nitride designs offer dependable ignition and fast warm-up, helping restore heat safely without repeated pilot attempts.

Thermocouples

A failing thermocouple often shows up as a pilot light that won’t stay lit. This safety sensor confirms the flame is present before gas flows. Universal thermocouples come in multiple lengths and millivolt ratings to fit common water heaters, wall heaters and older furnaces, for an easy, affordable fix that supports safe operation.

Radiator Vents & Valves

Steam radiator air vents and radiator valves help balance room-by-room heat and quiet noisy radiators. Replace sticky or hissing vents to improve heat distribution, and use quality shutoff valves for maintenance or seasonal adjustments. The right parts can reduce spitting, cut down on air in the system and boost comfort.

Installation and Ventilation Supplies

Finish the job with accessories that simplify installations, seal connections and improve air flow. Choosing the right materials helps prevent leaks, protect equipment and support efficient operation.

Duct Tape

For HVAC projects, choose tapes designed for ducts, such as UL 181 foil or HVAC tape, for durable, temperature-resistant seals on metal ductwork. General-purpose duct tape is useful for temporary fixes and household tasks. Proper sealing helps prevent air leaks that waste energy and strain your system.

Dryer & Vent Hose

Keep laundry rooms safer and dryers performing with the right vent hose and fittings. Select the correct diameter, use smooth metal where possible and secure connections with clamps or elbows designed for tight spaces. Replacing damaged or crushed hose can improve airflow and help reduce lint buildup.
