Water Heater Repair & Installation in Melissa, TX: 2026 Rankings
Water heaters aren't really their own trade in North Texas — they're mostly a plumbing job, with a handful of mechanical contractors handling gas tankless conversions on the side, so two names on this list also appear in our Melissa plumbing ranking. That's deliberate overlap, not padding: it reflects how the work actually gets done here. Our top pick, H2 Mechanical Services LLC, moved its operation to Melissa back in 2013 and holds a Texas TACLB84965C license covering both HVAC and water heater work. Masters Touch Plumbing Solutions, also based inside Melissa city limits with a Registered Master Plumber license, runs a dedicated water heater services page. With DFW tap water commonly running 10 to 17-plus grains per gallon of hardness, tank and tankless units in Melissa's newer builds scale up fast without regular flushing — worth asking any installer about before you sign.
How we ranked these four
We looked for a real Texas trade license relevant to water heater work — a Master Plumber or Registered Master Plumber number, or a TACL mechanical license for gas and tankless conversions — plus physical proximity to Melissa and a service page written specifically for water heaters rather than a single line buried in a general plumbing list.

Who is the best water heater company in Melissa, TX?
For 2026, our top pick is H2 Mechanical Services LLC, based in Melissa since 2013 and licensed (TACLB84965C) for both HVAC and water heater work. Masters Touch Plumbing Solutions, also Melissa-based with a Registered Master Plumber license, is a close second.
Is water heater work handled by plumbers or HVAC companies in Melissa?
Both. Standard tank water heaters are typically a licensed plumber's job, while gas tankless conversions often involve mechanical contractors who also handle HVAC work, which is why this list overlaps with our Melissa plumbing ranking.
How much does a water heater cost to replace in Melissa?
A standard 40-50 gallon tank replacement runs $1,200-$2,800 installed in North Texas for 2026, with most like-for-like gas swaps landing between $1,300 and $1,900. Tankless conversions run $4,500-$10,000 once gas line and venting work are factored in.
Does DFW's hard water affect water heaters in Melissa?
Yes. North Texas tap water commonly runs 10 to 17-plus grains per gallon of hardness, which accelerates scale buildup inside both tank and tankless units. Annual descaling flushes, typically $100-$200, meaningfully extend a water heater's service life.
