Requested service to two (2) gas fireplaces that stopped working & were quite dirty upon living in house for 10 yrs. Mark (Service Technician) arrived right at agreed appointment time & worked diligently on the issues. He recommended the best options based on my use of both fireplaces. Mark worked quickly, while ensuring quality service due to an unexpected appointment I had scheduled. Very satisfied with the work performed- both fireplaces are clean & in great working condition. Would recommend to others & will use for future needs.
