Get matched with top tankless water heater installers in Bay Pines, FL

"Two old shower pulls were hard to work and one leaking profusely. Also, water heater not making lots of hot water and 12 years old. Asked for a flush and recommendation for replacement. Tech showed up on time and ready to work. Rebuilt pulls quickly and knowledgeably. Attempted to flush water heater but too far gone. Showed me work done and patiently listened to and answered all my questions concerning replacement options. Gave me a good deal on new water heater and was available and ready to install same day. Completed the installation cleanly and efficiently. Couldn’t be happier with the experience. Tech (I’m sorry, I don’t remember his name) was professional and courteous and worked efficiently. Prices are fair and their use of a standardized pricing guide eliminated any feeling that they were pricing on the fly. Two thumbs up."

"I will say this they did what I wanted. However, it would have been better to have been told that it was not the best option. The plumber that arrived did the work but relied on the plumbing supply house to make suggestions on what tankless heater to use. I am aware at the time I did not have many options as I only had access to 110 service. The tankless heater that was installed really does not work for either the sink or my dishwasher much to my dismay. I went and bought a new dishwasher thinking that was the problem since my dishes were not getting clean and soap residue was present but I later learned it was because the water was not hot enough. The 4 stars for customer service is for the polite young man I spoke to on the phone who tried to rectify the problem by making the company aware of the situation. Although I did not expect them to do anything as some time had elapsed since the installation was done."

"Very prompt and quick to respond. First company to reach out to me with the desire to help me out. Great communication and showed up as promised on an Easter Sunday. I realize not the best day for water heater to break. I agreed to pay an additional $100.00 on top of their $124.00 service call price to get my water heater fixed on Easter Sunday. The plumber gave me an estimate of $480.00. Price was a little high, but they did come out at an inconvenient time for everyone. The plumber didn t have what he needed to fix the water heater-said he could come back first thing Monday. I completely understood - nothing was open. The plumber did show up Monday morning as promised and job was completed. The total charge was $549.00. Was very happy with the communication and the job they did."

"The plumber was quickly able to determine the cause of problem & repair the hot water heater."

"I called Cass in November 2021. The hot water heater went out the day before Thanksgiving. Richard, the service repairman, came out that day and replaced the heating element. This past week, almost 7 months to the day, no hot water again. Cass was very busy but Richard did make it out in 2 days. It was the heating element again. He replaced it again and mentioned our water was very 'hard'. There was no charge because it was under warranty. I am now planning to have Cass install a new tankless water heater. I would definitely recommend Cass for your plumbing needs. Richard was prompt, personable and qualified. Customer service is great!"
