What Customers Say

“My girlfriend, my mother and I have been dealing exclusively with Mersey Service Experts for several years because their service is second to none.

Today, Zhao from Mersey came to help me resolve an issue with my hot-water heating system. One radiator was always far too hot while another, fed by the same supply line, was always cold. This problem persisted throughout last year’s heating season even when the regulator valve on the hot radiator was completely shut off. I naively believed that this problem was caused by a defective regulator valve, which needless to say, would be very expensive to replace.

I was very relieved when Zhao explained that the problem was caused by an airlock within the system. He patiently adjusted and readjusted the system’s water pressure until he was convinced that the problem was resolved. He then taught me how to clear airlocks and how to set the water pressure to the correct level for my system.

For all of this, I was only charged for a service call, which cost me less than $100 including taxes. Thank you (谢谢) Zhao and thank you Mersey!”

“Had a hot water heater installed by Jordan and Mike – they did a great job optimizing placement and running intake/exhaust pipes, gas supply and water pipes to minimize obstruction in my basement. A professional job and they cleaned up everything afterwards. Thanks.”

Frequently Asked Questions

How often you need a new water heater depends on a variety of factors, but most need replacing every 7 to 15 years. Things like the model, quality of installation, and maintenance of your water heater can all impact how long it will last. If you think it’s time for a replacement, call us for a free in-home assessment and our experts will let you know for sure.

There are a few ways to tell if your water heater needs replacing. The most obvious way is if your unit isn’t working very well or isn’t working at all. But the best way to tell is to hear it from an expert. Our expert technicians will let you know at an annual maintenance appointment or at a free in-home assessment if your water heater needs replacing.

How long installation takes will be different for every home, but you can expect most water heater installations to take 2 to 4 hours. The model of water heater you choose and even its location in your home can impact the installation time. You can help make the process as quick as possible by clearing the areas we’ll be working in.

We try and complete every installation as quickly as possible while holding your water heater installation to the highest quality standards. The best way you can prepare your home for installation is by clearing any areas we will be working in. This includes clearing a pathway through your home and clearing out your furnace room.
