Called due to a rattle in our furnace. They were awesome in that they had a cancellation and were able to come out that morning. No sooner did the rep take the panel off, he said that our inducer was bad, the furnace was at the end of its life being 12 years old. He did not really check the furnace thoroughly and said he would get a sales rep out that day to go over buying a brand new furnace since a new inducer would cost $1900. He also mentioned our AC unit was at the end of its life despite us not having any issues with it. We cancelled the sales rep appointment and sought out a second opinion from another company. Turns out a sticker had blown in to the fan and then blown out causing the rattle. Since then, no rattle and furnace has been going for 30+ minutes at 78* with fan on high. Additionally, we were charged for a maintenance agreement that I nor my husband agreed too at a whopping $230ish dollars. I told the rep over the phone it s something we would discuss with the repairman once he arrived and found the issue. Instead, we were charged and nothing was explained to us. We thought it was a same-day charge until I started connecting the dots. Supposedly they were going to reverse it but haven t seen confirmation of it. So disappointed in this experience.
