I ordered a Terrova foot control pedal. This was the cheapest price by a significant amount. Delivery was quick.

great service and fast delivery. Thank you!

Package was beat up. Igniter was broken. Main gas pipe was also broken. Reused old parts from furnace I removed.

I tried to do a return and it will not accept the return

Quick & painless
