Example implementations of the present disclosure relate to systems and methods for improving the efficiency of a furnace. This process may include initiating combustion of the fuel in the burner assembly at an intermediate firing rate; operating the furnace in warm-up stage following initiating the combustion of the fuel, the warm-up stage including operating the burner assembly at the intermediate firing rate and not operating the circulation blower; operating the furnace in a boost stage following the warm-up stage, the boost stage including operating the burner assembly at the intermediate firing rate and initiating operation of the circulation blower; and operating the furnace in a low-capacity setting following the boost stage, the low-capacity setting including operating the burner assembly at a low-capacity firing rate, the low-capacity firing rate being a lower firing rate than the intermediate firing rate.
