I have had my unit for the past twenty-five years.
Typically, gas furnaces last for around 18 years.
The reason mine had lasted this long was because I took very good care of it. The heating business had provided me with a homeowner solutions guide that stated the importance of scheduling regular heater maintenance. When the boiler stopped providing quality heating even after the numerous boiler repairs, I knew It was time to replace it. I consulted the heating dealer since he knew more about heating than I did. He suggested I purchase a geo heat pump from the local company as they had an offer and this quality HVAC equipment would really come in handy in providing moderate temperatures all throughout the year. What was amazing was that this new HVAC would not need as much servicing as my previous unit. Although my previous unit was old, a neighbor of mine was able to take the components and creatively design a beautiful statue. It was nothing short of impressive. It was a statue of a huge rose. It looked beautiful. I put the statue in my house for decoration. The heating technician showed up at my residence the following day and installed the new system. The best thing about this unit was that it was compatible with a wifi thermostat which I could program to be voice-activated. This was such cool technology. The status reminded me of a unit that had served me for almost three decades. Everyone who came to my house commented on how beautiful the statue was. My neighbor even got a couple of referrals from me as everyone appreciated his skill and creativity. As far as I know, this new unit would last even longer than my previous one.
