Reliance Home Comfort

Had a new furnace and central air unit installed less than 10 years ago, annual maintenance on the regular, dust filter changed bi annually. A Saturday morning past there's a beeping and temperature drop (it's winter; lol). Upon checking the furnace control panel there were errors, called the service center they were closed. Called Reliance they'd be there before 6:00pm it was around 11am when I made the call. With in the time window the Reliance tech showed friendly, polite, understanding, personable, and professional. A short time later the furnace seems to be working the tech is preparing to leave when the beeping started anew, back he comes the circuit board he had just changed is faulty, another was installed still working. It been weeks since that day looking back on that day I'm thankful.
