Worked great. 01/23/2020
By Jeffrey Hazel
Furnace in my workshop was intermittently not starting when thermostat called for heat. Used the furnace manual to decipher the flashing LED code on the circuit board which indicated that the pressure switch was open for the induced draft blower. Induced draft blower exhausts combustion gases out through the PVC vent to outside. Found, the pressure switch, didn't look too scary, (never tried fixing a furnace before, but this one is away from living area), Google searched for PN, found these guys with the replacement equivalent. They shipped it out quickly, got it, two screws, two rubber lines and two push on wire connectors later, furnace works perfectly. Cost $25 with shipping, probably saved $150 or so over HVAC tech service call.

Fast and easy 05/20/2020
By Eric Maynard
I could not find the part I was looking for at any of the local HVAC stores. One quick online search brought me to Keith's and using the website made it extremely easy to find the part. I called the store and they were very helpful. I got the part from Keith's delivered to my house before I could get a call back from one of the stores on whether not the part was available for me to order. I will use this store for all future purchases. Good work!

Furnace PSI Switches 01/10/2020
By Roy Johnson
My furnace went out for one of these psi switches just before Christmas. Due to age, I chose to replace both.I checked the local supply shops, and no one had these, or ones that I could convert to easily. They had both, and at a better price. Shipping was quicker than other web sites said that they could get to me. Parts showed up on time as promised and worked perfectly. Will defiantly use them again.

Concord Furnace Pressure Switch 11/10/2014
By Curtis Davenport in MI
Found this site by accident searching for a replacement pressure switch and I'm glad I did. The price was much better than my local supplier. I ordered online on Sunday, paid with PayPal and received the part via UPS on Tuesday! Installed the part and the furnace is running like new......I couldn't be happier!

Thanks Keith Specialty, excellent service always wins!!

Got it fixed! 05/30/2019
By Jacob Anderson
Needed a pressure switch for the furnace and this replacement part did the trick. My only complaint it that it took 5 days to get here but the price was cheaper than everybody else and I wasn’t in a hurry.

Had a tough time finding the correct part, but found it for a good price here.
Shipping to Canada was expensive, but overall was still worth it.
