Does HVAC Include Water Heater? (Who Should You Call)

The water heater is one of the most essential appliances in your home. It provides hot water for showers, baths, dishwashers, and laundry machines.

This guide will help the reader understand, “does an HVAC service include a water heater?” and who they should call if it malfunctions.

What Does HVAC Consist Of?

The term HVAC stands for heating, ventilation, and air conditioning. The HVAC system is responsible for regulating the temperature and airflow in a home. It consists of the furnace, air conditioner, ductwork, and registers. The water heater is not traditionally considered to be part of the HVAC system; however, it can be included in some cases.

The HVAC system deals with appliances such as the refrigerator, oven, dishwasher, and clothes washer. These appliances produce heat and moisture that must be removed from the home in order to maintain a comfortable environment. The HVAC system does not include the water heater.

Is Water Heater Included In HVAC?

Let’s clear up whether a water heater is HVAC or plumbing. A water heater is a household appliance that produces hot water. It is usually in the basement or garage and connects to the plumbing system. The water heater is not part of the HVAC system, but it is included in the plumbing system.

The plumbing system includes the water heater, the pipes, and the fixtures. It is responsible for bringing water into the home and removing wastewater. It also includes the septic system or the municipal sewer system.

For example, when you take a shower, your plumbing system brings water into the bathroom but the water heater makes it heat up. HVAC has no part in that.

The HVAC system regulates the temperature and airflow in the home. It includes the furnace, air conditioner, ductwork, and registers. When you are feeling hot or cold, the HVAC system regulates that.
