Reliance Home Comfort

My 10-yr old, high-efficiency Trane furnace needed repairs. I was on the Reliance heating protection plan, so someone came to replace the circuitboard. It worked for 2 weeks, then the igniter went out. Something to do with the new circuitboard. A new igniter was ordered, delivered - but it was the wrong part. After some back and forth with the courier Reliance hired, it came a few days later and was installed. That went a week later. Very frustrating experience. After all that, they told me parts were too hard to find for this furnace and it needed to be replaced. I did some quick research and was satisfied with the price and product they proposed - a Rheem unit with a 5 yr warranty. It was installed the next day, which was great. Unfortunately the installers damaged a carpet and wall in the basement. Fortunately they paid me for the damages, although it was still an inconvenience. Lots of ups and downs. In summary, I had a good experience with all technicians and the saleman, but I was frustrated with the courier employed by Reliance (they mixed up the part with another order, making me wait an extra day or two), and the installers - a different company. I think Reliance needs to be more selective with its subcontractors.
