Water heater repair vs HVAC repair

Water heater service versus HVAC repair. Two different systems, sometimes confused — compare when to call which specialist.

Water heaters heat domestic hot water for taps and showers — they are plumbing appliances. HVAC systems heat and cool the air in your home. The confusion arises because both involve heating, but they are separate trades. If you have no hot water at the tap, you need water heater repair (a plumber). If your house is cold but the taps run hot, you need HVAC or furnace repair. Some combisystems blur the line — in those cases, start with HVAC. HireLocal lists both; compare local pros.
