Thank you Rocco for the attention and expertise you showed in fixing my plumbing problems today. Always a pleasure in seeing a friendly face. (Or half of one due to the face mask lol) Stay safe!!

Dark H

So glad we have the Reliance Plumbing Protection Plan! Plumbing is something you definitely want to leave to a licensed plumber. Rocco arrived on time, was courteous, knowledgeable and a true professional. Thanks Rocco!!

Sandra E

Exceptional. I got it all - new furnace, air filtration system, de-chlorinator, and reverse osmosis water system - and so far so good. The team from Reliance were all amazing, polite, respectful and competent. Everything went smoothly and was done in two days. Awesome job Reliance!

Jeff F

The service technician went above (the water heater) and beyond (the back of the furnace) to reattach a heating/cooling duct which had come loose. Is it possible to add the adjectives "Agile" and "Determined" to the above descriptor list?

Cupola C

Called reliance after my water heater that I owned started to leak late in the night. Reliance got a rental in place within 14 hours of my call. Rental price is reasonable too. Sales representative was very clear and very nice. Installer that came out was super nice and very good at his job. Very happy reliance customer.

Mike V

What I Love most about being an HCA is the interaction I have every day with homeowners. I get a gratifying feeling helping them find solutions to their concerns in regard to their home comfort and safety.
