Great guy and fast service. Hired another plumber originally who's price was outrageous more than double. Glad I've found someone trustworthy!

Thank goodness for Lazzaro Gas. We were told a gas line may need to be replaced, so we booked 3 companies to check this. Two said the pipe would have to be replaced at a huge cost, and Lazzaro Gas came out, dug further, and cleared everything with our gas company. We are so thankful there are honest companies that don't take advantage of regular people like us. Thank you. Highly recommend.

Such a pleasure to deal with! Came 1 day to disconnect the gas line (old gas dryer) and returned later to reconnect the gas line to the new dryer. Gabe went above and beyond what he was hired to do. We truly appreciated his help and expertise. Do not hesitate to contact Lazzaro Gas for your HVAC and gas needs, he will confidently see you through this quickly and professionally.

I needed a repair for my older natural gas pool heater. The Lazzaro team fit me into their schedule quickly and made the repair with no hassle. They were very transparent on their pricing. Would recommend.

Lazarro was a huge help with our pool heater! He came out as quickly as possible and had it fixed in less than an hour. He even took the time to look over our whole setup and gave us some great tips for keeping everything running smoothly.
