Is It Time for a New Water Heater?

A few clear signs usually point to replacement rather than continued repairs.

The tank is 10 to 15 years old
Repairs are becoming frequent
Rusty water from hot taps
Rising energy bills over time
Water is pooling near the tank
Not enough hot water anymore
Popping or rumbling noises persist

If several of these sound familiar, it’s worth having a technician evaluate your system before it fails and leaves your household without hot water.

What Your Neighbors Are Saying About Us

We have had a great experience with them for both AC service and our boiler. The service team is professional, knowledgeable, and kind. They also make a big effort to get your job taken care of as soon as possible.

Tom, Julian, and Collin did a fantastic job replacing my oil furnace with a natural gas one. This was a very involved oil to gas conversion and they did a fantastic job running the gas lines and installing the new water heater. They were very courteous and did a great job explaining everything. Fair pricing, I would highly recommend!

I've had to call Davis on several occasions with furnace issues. Each time it was fast responses pleasant & friendly technicians they were very informative & got my heater up & running fast. 5 stars from me.

Extremely happy with our experience. We scheduled a tune up thereafter and the technician Nick H professionally maintained our systems, gave us valuable recommendations, and personally rerouted some HVAC piping to help provide additional head clearance in our tight mechanical room without asking. Highly recommend all around.

Furnace was clicking but not igniting. Called Davis and they said they were backed up but would try to get to me. Half hour later they called and said a technician was on their way. Nick arrived and quickly diagnosed the problem. Am up and warming up! Great service! Would highly recommend

Advantages of Upgrading Your Water Heater

A new water heater typically operates far more efficiently than an aging unit, often resulting in noticeable savings on monthly energy bills. Older tanks gradually lose efficiency as sediment builds up and components wear out, so even a water heater that’s still technically running may be costing you more than it should every month. Newer units are also built with improved safety features and better insulation, helping to maintain water temperature more consistently while using less energy.

Beyond efficiency, a new installation often comes with a meaningfully reduced risk of leaks, since aging tanks are far more prone to corrosion and failure than newer equipment. Many homeowners also appreciate that a properly sized new unit resolves the frustration of running out of hot water partway through the day, a common complaint with older tanks that have lost capacity over the years or were undersized for the household from the start.

Water Heater Options to Consider

Traditional tank water heaters remain a popular choice for many Norristown homes, offering straightforward operation and a lower upfront cost compared to some alternatives. These units store and continuously heat a set volume of water, making them a dependable option for households with fairly predictable hot water usage throughout the day.

Tankless water heaters offer a different approach, heating water on demand rather than storing it in a tank, which means a continuous supply of hot water without the risk of running out during heavy use. While tankless units typically cost more upfront and may require adjustments to existing gas or electrical connections, many homeowners find the space savings and long-term efficiency worthwhile, particularly for households with higher hot water demand. Heat pump water heaters are another option worth considering, drawing heat from the surrounding air to warm water more efficiently than standard electric models. However, they perform best in spaces with adequate airflow and moderate ambient temperatures. Our technicians walk through the tradeoffs of each option based on your household’s hot water usage and home setup.

Our Water Heater Installation & Replacement Process

Every installation begins with an assessment of your current system, household hot water usage, and any specific concerns you’ve had with your existing unit. From there, we provide a clear, upfront quote so there are no surprises once work begins. Our technicians handle the removal of your old water heater and complete the new installation with care for your home, including proper connections to existing plumbing, gas lines, or electrical systems, depending on the unit you choose.

Once the new water heater is in place, we test the entire system thoroughly, confirming proper temperature output, pressure relief valve function, and overall safe operation before considering the job finished. We also walk you through your new system. Hence, you understand how to operate it and what maintenance it will require going forward, and we remain available afterward if any questions arise.
