Tankless Units in Comer Homes
Many Comer homes are brick ranches where the tankless went onto an outside wall or into the garage. Occasional hard freezes and gas supply sizing cause most of our calls.
What we run into in Comer
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.
- Retrofit installs. Retrofits are common in this housing stock. When a unit throws flame codes only while the furnace or dryer runs, the gas supply is the first suspect.

Call (380) 273-8196Tankless Problems We Fix Around Comer
When people phone about tankless water heater repair in Comer, GA, it is nearly always one of these problems. Each has a short list of causes.
Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.
Water under the unit
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.
Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.

Fix It or Retire It? Deciding in Comer
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.

Comer Homes by the Numbers
Electricity heats about 61% of homes in Comer, so electric tankless units, with their heavy-amp circuits and element faults, are as common here as gas ones. With a median build year of 1989, homes in Comer sit in the middle: plenty were retrofitted with tankless units, and plenty of those units are now old enough to need parts. Comer is about evenly split between owners (around 59%) and renters, so calls come from homeowners and from landlords and property managers alike.

Comer Weather and Water Temperature
Freezing nights are not constant in Comer, about 40 a year, but the coldest one in the last three years reached about 10°F. A unit mounted outdoors or in an unheated garage is exposed on those nights, and a leak found in spring often started in January.
In Comer the cold tap is probably around 53°F in winter and 72°F in summer, based on a January average of 44°F, a July average of 82°F and a yearly average of 63°F. Heating that water to 120°F takes a rise of about 67°F in winter, so a 199,000 BTU gas unit at 90% efficiency tops out near 5.4 gallons per minute, compared with roughly 7.5 in summer when the rise is only about 48°F.
For comparison, a shower draws roughly 2 gallons per minute, so two at once plus the dishwasher can pass the winter figure. If the water goes lukewarm only when several taps run, the unit is likely maxed out; if it goes lukewarm at one tap, the cause is more often scale, a flow sensor or the flame.
Comer sits near 694 ft, well under the 2,000 ft level at which gas appliances commonly need altitude adjustments, so burner output should not be a concern from elevation alone.

Tankless Water Heater Repair in Comer, GA: FAQs
Question not covered here?
Call and ask. Someone who repairs tankless units answers, and the phone quote is free.
Call (380) 273-8196How much does tankless water heater repair in Comer, GA cost?
Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.
How long does a tankless water heater last?
Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years. In Comer the heat exchanger works through a rise of about 67°F on a typical winter day, which is why flushing on schedule matters there.
Why does my tankless water heater go hot then cold?
A brief cold slug after a tap reopens is the unit restarting. Swings during one shower usually mean flow below the unit's minimum, scale on the exchanger, or a failing flow sensor. Around Comer the winter supply is likely near 53°F, which limits a typical gas unit to roughly 5.4 gallons per minute at 120°F, so a swing that only happens with several taps open is usually that limit.
Can a tankless water heater be repaired?
Usually, yes. Nearly every part on a tankless unit can be replaced, and a scaled exchanger can be cleaned. The exception is an old unit whose heat exchanger has started to leak.
