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

Common Water Heater Problems We Fix

A failing heating element or pilot light issue is one of the most frequent problems we see, often resulting in water that won’t heat at all or takes far longer than usual to warm up. Sediment buildup inside the tank is another common culprit, particularly in areas with hard water, and it can cause popping or rumbling noises and reduced efficiency over time. As sediment accumulates, it insulates the bottom of the tank from the heat source, forcing the unit to work harder to heat the same amount of water.

We also regularly address thermostat malfunctions, which can cause water temperature to fluctuate unpredictably or run hotter or cooler than the set temperature. Leaks are another common concern, sometimes originating from a faulty pressure relief valve and at other times from corrosion inside an aging tank. Anode rod deterioration is a less visible but important issue we check for as well, since a worn anode rod accelerates corrosion inside the tank and can shorten the unit’s overall lifespan if left unaddressed.

Our Water Heater Repair Process

When our technicians arrive for a water heater repair, we start with a full diagnostic that covers the heating element or burner assembly, thermostat, pressure relief valve, and tank condition, rather than assuming the cause based on symptoms alone. This helps us catch related issues that might not be obvious from the original complaint, since several components can contribute to a similar symptom.

Once we’ve identified the actual source of the problem, we explain what we found and what repair options make sense before any work begins. We carry parts for most major water heater brands, which allows us to complete many repairs in a single visit. After the repair is finished, we test the system through a full heating cycle to confirm proper temperature output and safe operation before considering the job complete.

A water heater failure rarely happens at a convenient time, and a leaking tank, in particular, can quickly cause water damage if it isn’t addressed right away.

Frequently Asked Questions

Why is my water heater making popping noises?

This is often caused by sediment buildup inside the tank, which insulates the heating element and forces the unit to work harder.

Why does my hot water smell strange?

A foul odor can indicate bacteria buildup inside the tank or a corroding anode rod, both of which should be inspected soon.

How quickly can you respond to a water heater emergency?

Our 24/7 on-call service means a technician can typically respond the same day, including nights and weekends.

Can a leaking water heater be repaired instead of replaced?

In some cases, yes, especially if the leak stems from a valve rather than the tank itself. Our technicians diagnose the source of the issue before recommending a repair or replacement.

How long does a typical water heater repair take?

Most water heater repairs are completed within 1 to 2 hours, depending on the issue and the unit’s age.
