The average lifespan of an air conditioning unit is 10-15 years, while the average lifespan of a furnace unit is 15-25 years. It is simply impossible to tell you exactly how much life your hvac system has left because there are so many factors that cannot be accounted for. What we do know is that you can help to lengthen the life of your air conditioning and heating system by ensuring that the air filters are regularly changed and the outdoor unit is clean.

You should consider calling a technician to your home if your AC or heating system isn’t doing what it is suppose to be doing. For instance, if you are trying to heat your home, but after 10 minutes the air coming out of your vents is either room temperature or cold, then call a technician. Or, if you’re trying to cool your home and the air coming out of your air registers is either hot or room temperature, then call a technician. If you are trying to run your HVAC and there is no air coming out from your vents, then we suggest to call a technician.

The single most common HVAC issue that we see homeowner have, which can be easily rectified are dirty air filters. If you have pets in the home that shed, we suggest changing your air filters 3-4 times per year. If you don’t have pets, then we suggest to have your air filters changed 2 times per year, once before summer, once before winter. A dirty filter can be the root cause of a variety of different issues.
