My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

Average rating: 1 out of 5 stars
To be short,An alarm system was installed for free but a five year security plan was signed., never worked properly , after many ,many repair visits and 1 year or so passed without feeling safe , we had to get a new company, marran would not give up on contract and had to go to small claims court ., which by the way was full of marran customers. Terrible experience!! Don’t do business with them!

They installed a full central ac setup for my house is Nesconset. It works perfectly. I look forward to using it again this summer.

Absolutely Phenomenal Service! Phenomenal service from all of the people at Marran. My boiler failed completely, which I confirmed with second opinions. Marran replaced it and got it up and running the next day.

Good quality work. Would hire again. The service guys did a very thorough job installing a new boiler. The person who maintains my boiler said it had a leak, but I wanted a bigger company to do the replacement, so I hired Marran Oil to do it.

They installed a new water tank, and I now have as much hot water as I could want. I didn't even run out when I had six house guests at once. I also have them deliver oil to the house.

They replaced my boiler. I haven't had any problems with the new one, and I'm using less oil. The people who installed it were very professional and friendly.

I had Marran install some nest thermostats, and the man who came did a great job. I will call them again next time I need security or HVAC work done.

Commented: How much energy would I save with this boiler?Hi Ed! It depends on a lot of factors, including which system you have now, and the size of your house, but our average customer saves about 30% on their bills after they switch. Give us a call, and w...
