My water heater broke and water was spilling out. It was after hours and we called Mullen Refrigeration. They were very prompt in responding. Tim the service technician arrived and installed a new water heater. He was highly knowledgeable and thorough with the installation. Thank you Mullen Refrigeration for the great service. I highly recommend this company.

5 stars, fantastic service. Hot water tank died overnight. Within 2 hours of calling Mullen, we had a brand new tank and supply line valve installed, all at a very reasonable price that beat my expectation. Will recommend to anyone.
