"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Abraham was awesome! He installed a new oil furnace system and did a conversion and disconnect for my new water heater also to be installed. Which I will review separately since it was two jobs. As far as, the heating system he listened to what was important to me as far as the energy-saving factor and efficiency of a new unit. I also wanted a great warranty and to know that he would be able to maintain and service my heating unit for-- tip-top condition for years to come. He made all of this happen! The tenants also gave him a rave review for his professionalism and knowledge to explain what he was doing every step of this job. It was also mentioned that he was neat and clean throughout the job. As I am an out-of-state owner he was communicative and kept me updated on progress via pics. Would highly recommend it and definitely will use it again in the future!"

"Expensive, but came when it was an emergency. Checked most of the boiler (not the hot water coil). Gave a complete price for all their recommendations. I agreed to ALL of their recommendations. Paid in full. But have not done the service part and even changed the appointment to do this service from November 11 to December 6. Seems if they came all the way here and spent 4 hours to evaluate, and fix at their suggestions, it would be time efficient to stay one more hour to finish what was paid for."
