Bad service, unprofessional, angry furnace service owner/sole technician for his business who refused to honor the 90-day warranty of his own work and could not handle customer questioning and complaint. He charged me twice for the same service 87-days apart. The owner of Champion Heating and Plumbing and sole furnace-service person first came out to fix my furnace in November 2015 to address a no heat service call. He charged me for a furnace inspection, no heat service call, and evap coil cleaning. He recommended monthly filter change with 20x25x1 filter. I trusted him being the pro and had been replacing with that size ever since. I did not like his attitude being arrogant at that time. But he did get my furnace working. In October 2018, the same problem arose, "system tipping on high limit." I called the furnace business with magnet ad attached to my furnace mistakenly thinking that was the business I used prior to 2015 because I did not want to use the same service as 2015. That was my fault. I later found out that he was the same person/serviceman. I was desperate with a cold house at that time, so I used his service. Again he serviced the furnace with a 15-minute service call and evac cleaning with a 90-day no breakdown guarantee. Surprisingly, 87 days later, my furnace broke down. He refused to honor his own handwritten warranty on top of the printed warranty on the service order invoice. I insisted on the warranty. He got upset, was shaking, and called me a Pitbull. This is witnessed by my boyfriend and my boyfriend told him to leave. The angry serviceman still charged me for the repeat service. My furnace is still not working and I have to hire somebody else so I do not have to use portable heaters. I am nervous writing this review but other consumers have to be aware. The serviceman insisted my furnace still works. My house is cold without the use of portable heaters as the heat keeps turning off by itself before it reaches 71 degrees where I have the thermostat set at. Also, the size of the filter he told me to get is wrong. It fell down because it was too small so it was his fault that I had the wrong size. My furnace was running without a filter. And then he changed what he wrote on the invoice about the size 20x25x1. He now said I need to order a customized size of 22x25x1 that is not available premade. He again placed the wrong size in my filter too small which I paid for and taped it to place which he did not do before so it will not drop out of place.
