Jackson Systems & Supply is an HVAC parts and controls supplier in Indianapolis, Indiana, serving customers since 1997. Its online store is built around heating and cooling contractors, but anyone can buy. The range runs from thermostats by Honeywell Home, ecobee, Emerson, PRO1 IAQ and its own iO HVAC Controls brand to zoning dampers, gas valves, motors, capacitors, condensate pumps, air cleaners and full equipment such as furnaces and air conditioners. It suits technicians stocking a van, and homeowners who know the exact part they need.

In-stock orders placed before 2 p.m. Eastern on a weekday ship the same day, and standard shipping is free over $99 to the contiguous US. It also ships to Canada and Mexico. Many products are professional grade, and Jackson Systems points out that manufacturer warranties may need a licensed contractor to install them.

What's worth a look

Here are six products from the current range, with the prices when we checked.

Thermostats are the store's core. The iO HVAC Atlas 3H/2C thermostat is on sale at $29.99, down from $56.33, and handles multi-stage heating and cooling. If you want a smart thermostat, the ecobee Smart Thermostat Lite is $159.99.
