Typical line voltage spec is ±5%. 110 x 1.05 ≈ 115.
120v has been the US standard since 1967 🙄
120 * 1.05 = 126.
126 volts is ≈30% power increase into 110v transformer resistance [which will increase a little from excess power dissipation]
Check your mains voltage and get written certification from the manufacturer that the unit is 120v nominal rated. Insurance companies can be sticklers.
