Last night our furnace decided to call it quits on the holiday weekend Saturday . We called Primo Heat Inc., and they responded within a couple of hours. Our ignition box had failed on our Lennox furnace. Luckily Dave had one on his truck and had us fixed up. Heat is now working, filter is changed, and he also did a carbon test to ensure safe operation. They also charged me regular rate even though it was on Sunday. This company goes over and above the call of duty. I highly recommend them
