Great product and price

Sunday, September 23, 2012

When my furnace started running erratically, local HVAC companies wanted hundreds of dollars for this module and more hundreds to install it. Estimates ranged from $450 to over $700. After reesearching the part on the internet, I bought the module here, payed a few extra dollars for overnight delivery, and installed it myself. Drillspot saved me so much money I ordered another mnodule as a "backup" - just in case. This is a terrific site.

Cost, ease of ordering, and easy installation

Nothing - it works better than the original

Thankful for This Item!

It was great to find this replacement part for our 26 year old furnace, it has saved me major $$$ and was shipped quickly, in-depth instructions made the installation fairly simple.

Great improvement from the original, the LED lights let you know at a glance, the status of the module and also if it was or wasn't installed correctly... I got it right on the first try!!

DrillSpot had just what I was looking for a great price and I was able to request express delivery for a few extra bucks so I could install it in my duplex in a timely manner. Thank you DrillSpot!
