"I AM BUYING A HEATER SERVICE CONTRACT FROM PETRO THIS YEAR."

"JDL replaced a defective propane furnace and did an excellent job. The new one is installed better than the original. JDL scheduled an inspection by the county inspector also said they did an excellent job. They were efficient, timely and friendly."

"I had a leak somewhere in my heat pump system from 2013 in a 4 floor condo building. Every other company was quoting me $7k+ to replace the system but it turns out to be a leak in the line set between the 3rd floor and the roof! We had a new line set installed and I spent $2550 in total! The crew was very professional and worked extremely had in the hottest weather to get the job done, too!"

"I won't know until next week how it went so hopefully it will still be 5 stars. They will start on installation soon. So far they have been very responsive and professional. Thanks, Janice"

"I was impressed by how hard working and thorough the workers were. They hauled the old gas water heater out and got the new one installed promptly and did a neat job. They reconfigured an awkward gas pipe near my washing machine, replaced an exterior gas hose with a UV resistant one, and checked all gas piping including our gas fireplace. We were very pleased with the end result and appreciated the fair pricing. Highly recommend."

"It was worth the cost to have a spacious vehicle and not to worry whether they would show up and be on time, but on the return trip there were plenty of cabs waiting at the Metro station, and we paid one of them less than half that. Still, next time I *have* to get to an airport or train station on time, I would probably pay that premium to use him again."

"Great, Heil fixed the plumbing for my irrigation off the main, it was leaking and a mes. They cleaned it up and installed new PVC. It works great and no issues. Fair price. I'd hire them again. Paul"
