Birmingham's Navien Certified Specialists
Certified Expertise for Tankless Water Heater Service
A&K Plumbing holds certified specialist status for Navien tankless water heaters, backed by annual manufacturer training. That means when something goes wrong with your unit, or when you are planning a new installation, you are getting a technician who knows these systems at a deep, brand-specific level. Most plumbers can swap a tank water heater. Far fewer can accurately diagnose a heat exchanger issue, troubleshoot a flow sensor fault, or properly size a tankless unit for a high-demand Birmingham household. Our certification closes that gap. We service Navien units throughout Birmingham, Homewood, Mountain Brook, Hoover, and the surrounding area, and we bring the right diagnostic tools to every call.
What We Handle
Tankless Water Heater Repair, Replacement, and New Installs
Our tankless water heater service covers the full range of residential needs. For repair calls, we troubleshoot loss of hot water, error codes, inconsistent output, and gas supply issues connected to your unit. For water heater replacement, we remove your existing equipment, handle all gas line connections, and commission the new unit to manufacturer specs. For new installations, we assess your home's demand, recommend the right unit size, and handle the full rough-in including gas line work if needed. As a Master Gas Fitter operation, we are qualified to run or modify the gas lines that feed your tankless system, which is a step many plumbing firms have to subcontract out. At A&K, it is all handled in one visit by one crew.
Why Homeowners Choose Tankless
The Case for an Energy-Efficient Water Heater
Traditional tank water heaters keep 40 to 80 gallons of water hot around the clock, regardless of whether anyone in the house is using it. A tankless water heater heats water on demand, which eliminates that constant energy draw. For homeowners in Mountain Brook, Homewood, and Hoover who are investing in high-value properties, switching to an energy-efficient water heater is a practical upgrade that reduces operating costs and frees up physical space. Tankless units also tend to outlast traditional tanks by a significant margin when they are properly installed and serviced by a certified technician.
Honest Pricing, No Pressure
A Flat-Rate Assessment and Non-Commissioned Technicians
Every tankless water heater service call starts with a $99 flat assessment fee. That fee covers a thorough diagnostic by a trained technician, and it is applied directly to the cost of your repair or installation if you proceed. You will never be handed a bloated estimate padded with parts you do not need. A&K does not pay its technicians on commission, which means the recommendation you receive is based on what your system actually requires, not on what earns the technician a bonus. Owner KC Margaritis built this firm on that principle from day one, and it remains the standard for every call across Birmingham and the surrounding communities.
Tankless Water Heater Questions
Answers About Our Tankless Water Heater Services
What does it mean that A&K is a certified Navien specialist?
A&K Plumbing holds certified specialist status specifically for Navien tankless water heaters, which requires completing annual manufacturer training. This goes beyond a general plumbing license. Technicians are trained to diagnose brand-specific issues, use the correct diagnostic tools for Navien units, and install or service those systems to the manufacturer's exact specifications. For homeowners in Birmingham investing in a Navien unit, this certification means the technician working on your system understands it at a deeper level than a generalist plumber would.How much does a tankless water heater assessment cost with A&K?
A&K charges a flat $99 assessment fee for all service calls, including tankless water heater visits. This fee covers a thorough diagnostic of your unit by a trained technician. If you choose to move forward with the recommended repair or installation, the $99 is applied directly to the total cost of the work. The fee is not a deposit or a separate charge on top of the repair price. It is credited back, so you are essentially paying for a professional evaluation that counts toward whatever work gets done.Can A&K handle the gas line work that a tankless water heater installation requires?
Yes. A&K Plumbing operates as a Master Gas Fitter, which means the team is qualified to install, modify, or repair the gas lines that supply a tankless water heater. Many standard plumbing companies have to subcontract gas line work to a separate trade, which adds time and coordination to the project. Because A&K holds Master Gas Fitter certification, a single crew can handle both the plumbing and gas connections for a new tankless installation or a replacement, covering the full scope of the job in one visit.What types of tankless water heater problems does A&K repair?
A&K handles a wide range of tankless water heater repair situations, including loss of hot water, error code diagnostics, inconsistent water temperature, and gas supply issues affecting the unit. The team uses brand-specific diagnostic tools, particularly for Navien systems, to identify the root cause rather than guessing. Common issues like heat exchanger faults or flow sensor problems require a technician who knows the system well. A&K's certified Navien training is specifically aimed at closing that gap for Birmingham-area homeowners.Does A&K serve areas outside of Birmingham for tankless water heater work?
Yes. A&K Plumbing serves a wide area around Birmingham, including Homewood, Mountain Brook, Hoover, Indian Springs, Irondale, and Trussville. The firm is headquartered in Homewood and operates a fleet of branded service vans that cover these communities.What are the practical benefits of switching from a tank water heater to a tankless unit?
A traditional tank water heater keeps a large volume of water heated continuously, even when no one in the household is using hot water. A tankless unit only heats water when it is needed, which removes that constant energy draw. For homeowners in higher-value neighborhoods like Mountain Brook or Homewood, an energy-efficient water heater can reduce operating costs and recover physical space previously occupied by a large tank. Tankless units also tend to have a longer operational lifespan when installed and serviced correctly by a certified technician.Will A&K recommend parts or services I do not actually need?
No. A&K does not pay its technicians on commission, which is a deliberate policy set by owner KC Margaritis. In firms where technicians earn bonuses based on what they sell, there is a financial incentive to recommend additional parts or services regardless of whether the customer needs them. At A&K, technicians are paid a straight wage, so their only job on a service call is to diagnose accurately and fix what is actually broken. The $99 flat assessment fee reinforces this approach by ensuring the technician's focus is a correct diagnosis, not a larger ticket.
