Whether your unit is on its last leg or you’re looking to upgrade to energy-efficient technology, you can trust our plumbers to get the job done right.

New Water Heater Installation – Built for Comfort and Efficiency

If you’re building a new home or upgrading an aging system, choosing the right water heater is key to long-term performance and savings. We offer complete installation services for all major types and brands of water heaters, including:
  • Traditional tank water heaters (gas or electric)
  • Tankless (on-demand) water heaters
  • Hybrid or heat pump water heaters
  • Commercial high-capacity units
Our team will help you select the right system based on your home size, water usage, energy preferences, and budget. We handle everything from permits and plumbing hookups to venting, gas line adjustments, and final inspections—so your new system is fully operational and compliant with Kent building codes.
We also specialize in tankless water heater conversions, perfect for homeowners looking to save space, energy, and time with endless hot water on demand.

Water Heater Repairs – Fast Fixes You Can Rely On

No hot water? Strange noises or rust-colored water? These are signs your water heater may need professional repair. At Design West Mechanical , we provide prompt, reliable water heater repairs to get your system back up and running—fast.
Common water heater issues we repair:
  • No hot water or inconsistent temperature
  • Pilot light won’t stay lit
  • Leaking tank or pressure valve
  • Sediment buildup or discolored water
  • Strange banging or rumbling sounds
  • Faulty thermostat or heating element
We’ll diagnose the issue, walk you through your options, and provide an honest recommendation—whether it’s a quick fix or time for a replacement. Our trucks are stocked with common parts so we can often complete repairs in a single visit.

Water Heater Replacement – When It’s Time for an Upgrade

Most traditional water heaters last about 8–12 years, while tankless systems can last up to 20 with proper care. If your system is nearing the end of its life, constantly needs repairs, or struggles to keep up with demand, a replacement may be the more cost-effective solution.
At Design West Mechanical , we make the replacement process easy and stress-free:
  • Free consultations and system assessments
  • Proper disposal of old units
  • Efficient, code-compliant installation
  • Manufacturer-backed warranties
  • Optional upgrades for energy efficiency
Replacing your water heater not only improves comfort but can also lower your utility bills and reduce your carbon footprint—especially if you opt for ENERGY STAR® certified equipment.

Preventive Maintenance – Extend the Life of Your Water Heater

Want to avoid cold showers and unexpected breakdowns? Regular maintenance is the key to long-lasting performance and energy savings. We offer annual and bi-annual water heater tune-ups that include:
  • Tank flushing to remove sediment
  • Anode rod inspection and replacement
  • Thermostat calibration
  • Leak checks and safety valve inspection
  • Burner and pilot light cleaning
Whether you have a tank or tankless system, routine care can help you avoid costly repairs and keep your water heater running efficiently for years to come.

Great experience with Design West Mechanical! Called late on a Saturday evening and talked to Joe. Since it wasn't an immediate emergency, we agreed to address the issue on Sunday. Joe called to confirm in the morning, arrived 15 minutes later, and replaced the parts by noon. The repair cost was reasonable and Joe was professional and personable. I would recommend their services.

I had a floor drain backup and flood part of my basement on a Tuesday evening, I called and Joseph was out the next morning to start diagnosing and fixing the problem. The clean out was in a very odd spot under a cabinet and he was able to come up with a solution to get to it and snake the pipes without having to remove the the full cabinet. He was able to clean the pipe and also show me the integrity of the pipe and location of the pipes with his camera and locator. I will definitely be calling them for any of my future plumbing needs.

Design West Mechanical, specifically Joe and Tarryn, are professional, trustworthy, and fair. My wife and I had Joe "hook-up" a natural gas line to run our generator. It worked out so well during the " bomb-cyclone" event! Thank you Joe and Tarryn for keeping my family warm and safe. I highly recommend Joe and Tarryn of Design West Mechanical.

Responded quickly, did a good job replacing a dead sump pump, very easy to work with. Did job for quoted reasonable rate, didn't charge for follow-up visit next day. Very impressed. He also gave some ideas for lowering our need for a sump pump.

Accountable and very knowledgeable cuts to the chase. Love working with Joseph and crew gets the job done right every time. I used to hate calling a plumber they always give you the go around always want to do extra work that doesn’t need to be done. Calling them is peace of mind knowing that the job will get done right the first time.
