Smart Thermostats for Houston & Brazoria County Homeowners: A Guide to Better HVAC Control & Energy Savings

What Is a Smart Thermostat?

A smart thermostat is a connected HVAC control that can automatically adjust heating and cooling settings based on programmed schedules, temperature preferences, occupancy information, and other available inputs. Unlike a basic manual thermostat, it can provide additional automation and remote control.

Many smart thermostats connect to a home's Wi-Fi network and allow homeowners to manage temperature settings through a smartphone, tablet, or computer. Depending on the model, features can also include learning capabilities, geofencing, room sensors, humidity monitoring, and HVAC-use information.

Common smart thermostat features include:

• Wi-Fi connectivity

• Smartphone and remote control

• Programmable schedules

• Learning capabilities

• Occupancy or temperature sensors

• Geofencing

• Energy-use information

• Voice-assistant compatibility

• Vacation settings

• Maintenance or system alerts

The exact features vary by manufacturer and model.

How Does a Smart Thermostat Work?

A smart thermostat communicates with the HVAC control system to manage heating and cooling according to the settings and capabilities programmed into the device.

Depending on the model, a smart thermostat may use information from:

• Indoor temperature sensors

• Room sensors

• Occupancy sensors

• User schedules

• Smartphone location for geofencing

• Outdoor temperature or weather information

• User-selected comfort preferences

The thermostat uses this information to determine when the HVAC system should operate and what temperature settings should be used.

A smart thermostat does not increase the heating or cooling capacity of an air conditioner, heat pump, or other HVAC equipment. Its primary function is to improve control over when and how the equipment operates.

What Are the Benefits of a Smart Thermostat?

Smart thermostats can provide more control and automation than conventional thermostats. Their usefulness depends on the home's HVAC system, the thermostat's capabilities, and how the homeowner uses its features.

Can a Smart Thermostat Improve Energy Efficiency?

A smart thermostat can help reduce unnecessary HVAC operation by adjusting temperature settings when heating or cooling is not needed.

For example, homeowners may use automatic schedules or occupancy-based features to reduce conditioning while the home is unoccupied. Some models can then restore a preferred temperature before occupants return.

Potential energy-management benefits include:

• Adjusting temperature settings during unoccupied periods

• Creating automatic heating and cooling schedules

• Reducing unnecessary HVAC runtime

• Using occupancy or geofencing features

• Reviewing HVAC-use information

• Adjusting settings remotely

ENERGY STAR notes that certified smart thermostats are independently evaluated using real-world data to demonstrate energy savings. However, savings are not identical for every household and depend on factors such as climate, occupancy, equipment, and thermostat use.

Can a Smart Thermostat Improve Comfort?

Smart thermostats can make it easier to maintain preferred temperature settings throughout the day.

Models that support additional room sensors can provide temperature information from multiple areas of a home. This can be useful when different rooms experience different temperatures because of factors such as solar exposure, insulation, or room location.

A thermostat can manage the HVAC system, but it cannot independently correct underlying problems such as inadequate insulation, restricted airflow, poorly distributed ductwork, or an improperly sized HVAC system.

How Does Remote Thermostat Control Work?

A Wi-Fi-connected smart thermostat can allow homeowners to change HVAC settings through a compatible mobile application.

Depending on the model, remote control may allow homeowners to:

• Change temperature settings

• Adjust schedules

• Activate vacation settings

• Review temperature or equipment-use information

• Receive system notifications

• Change settings while away from home

Remote access can be useful when plans change or when homeowners want to adjust the HVAC schedule before returning home. ENERGY STAR identifies remote control as a common feature of certified smart thermostats.

How Does Smart Thermostat Scheduling Work?

Smart thermostats can automate temperature changes according to a schedule.

A homeowner may create different settings for:

• Morning

• Work or school hours

• Evening

• Sleeping hours

• Weekends

• Vacations

Some smart thermostats can also learn temperature preferences or occupancy patterns and use that information to create or adjust schedules.

What Are Learning Thermostats?

A learning thermostat is a type of smart thermostat designed to adapt to household routines and temperature preferences.

Depending on the model, learning features may use information such as:

• Temperature adjustments

• Time of day

• Occupancy

• Home and away patterns

• User preferences

Learning capabilities vary considerably between manufacturers, so homeowners should review the specific features of a thermostat before purchasing it.

What Are Energy-Use Reports?

Some smart thermostats provide information about HVAC operation and temperature history.

Depending on the model, homeowners may be able to review:

• HVAC runtime

• Temperature history

• Energy-use trends

• Schedule information

• Efficiency recommendations

This information can help homeowners understand how their HVAC system is being operated. ENERGY STAR certified smart thermostats are required to provide information about HVAC energy use, such as monthly runtime.

How Does Geofencing Work on a Smart Thermostat?

Geofencing uses location information from a compatible smartphone or other device to determine whether occupants are near or away from home.

When enabled, a thermostat may adjust HVAC settings after occupants leave and restore preferred settings as they return.

Geofencing can reduce the need for homeowners to manually change the thermostat when their daily schedule changes. The feature depends on the thermostat, its application, permissions, and connected devices.

Can a Smart Thermostat Work With Voice Assistants?

Some smart thermostats can integrate with compatible voice-assistant platforms.

Depending on the thermostat and connected system, homeowners may be able to use voice commands to change temperature settings or perform other supported controls.

Compatibility should be checked between the thermostat, voice-assistant platform, and other smart-home equipment before purchase.

Why Does Heat Pump Compatibility Matter?

Heat pumps can have control requirements that differ from conventional air-conditioning and furnace systems.

A compatible thermostat must correctly communicate with the heat pump and any associated auxiliary or backup heating equipment.

Homeowners with heat pumps should verify compatibility before installation rather than assuming that a thermostat designed for a conventional central air conditioner will provide the correct controls.

When Should You Consider Replacing a Thermostat?

A thermostat upgrade may be worth considering when the existing thermostat no longer provides the control features or scheduling options a homeowner needs.

Common reasons for considering an upgrade include:

• A manual thermostat requires frequent adjustment

• An older programmable thermostat is difficult to configure

• Remote control would be useful

• The household schedule frequently changes

• Temperature settings are difficult to manage while away

• The homeowner wants additional HVAC-use information

• The existing thermostat does not provide desired smart-home features

A thermostat upgrade is not necessarily the solution to an HVAC performance problem. If a home has persistent comfort problems, the HVAC system, airflow, ductwork, insulation, and equipment sizing may also need to be evaluated.
