One question we want to answer is whether there’s such a thing as too much maintenance. The answer is certainly “yes!”
To keep your heater or air conditioner in good shape, you only need to have it checked once a year. So, if your heater and AC are two separate systems (i.e. not a heat pump), then you’ll actually be scheduling maintenance two times in the year.
On this note, we want to talk specifically about why gas furnace maintenance is not the maintenance you want to skip. In addition to some operational issues, neglected maintenance can also bring about safety hazards.
