Are Wireless Smart Thermostats Worth the Investment?

After purchasing a new programmable thermostat, the next question you will likely have is how to install and configure it. 

Depending on the wireless smart thermostat you purchase, you may encounter a complicated installation process. At least, this is how it may first appear. The good news is that the setup procedure is frequently far simpler than the manufacturer’s instructions make it appear. 

Manufacturers have a propensity to employ technical writers who transform relatively easy jobs into extensive undertakings. Assuming you have a conventional HVAC system, you should be able to configure your wireless smart thermostat using only a few common tools. 

How do thermometers operate? 

First and foremost, how do thermostats function? 

The functioning of traditional thermostats is based on simple scientific concepts. The gadget manages the heating and cooling systems in your home by monitoring the ambient temperature and activating or deactivating the HVAC systems accordingly. A thermostat is surprisingly straightforward and has some intriguing technologies. 

Almost all thermostats manufactured in the last two decades are digital, however, older homes may still have analog thermostats. Most conventional thermostats use a mercury switch, which is a glass vial containing a tiny quantity of liquid mercury. The mercury is electrically conductive and flows like water. 

Your thermostat uses connections to decide when to turn on the heat and when to turn on the air conditioning. Traditional thermostats began to be replaced with programmable thermostats in the late 1990s. 

Signs You Need a New Thermostat 

Thermostats, like every other component of an HVAC system, are susceptible to failure and will ultimately require replacement. Knowing the warning indications that your thermostat is reaching the end of its useful life will help you to replace it before your HVAC system becomes inoperable. Consider these four indications that your thermostat needs to be replaced.

  • Improper Temperature Readings

If your thermostat misreads the current temperature, you cannot rely on it to heat and cool your house properly. There are a variety of causes for inaccurate thermostat readings, not all of which necessitate replacement. Occasionally, repositioning or re-leveling your thermostat is sufficient to restore correct temperature readings.

If your thermostat is level and shielded from drafts and bright sunshine, you may need to clean it. The accumulation of dust within a thermostat can form an insulating layer, rendering the device’s temperature readings significantly less precise. If erroneous readings persist after cleaning the thermostat, it is likely that a technical flaw necessitates replacement. 

  • Blank Display

Never allow blank digital screens on contemporary thermostats. Even when not in operation, the majority of thermostats display the current temperature, time, and perhaps other data. A thermostat with a blank display is an indication that it should be investigated.

Checking the thermostat battery and the circuit’s breaker or fuse is the first step in diagnosing a thermostat with a blank display. In uncommon instances, your thermostat may have switched off because a safety switch in your HVAC system was activated. The activation of safety switches may result from a clogged condensate drain pan or an overheated heat exchanger.

When inspecting your system, if you discover no indication of these issues, the next potential failure point is the cabling that supplies electricity to your thermostat. If your thermostat wasn’t properly fitted, the internal wire may have been separated from the contacts. An expert in heating, ventilation and air conditioning (HVAC) may examine your thermostat to determine whether faulty wiring or replacement is necessary. 

  • Difficulty Saving Configurations

Wireless smart thermostats include customizable capabilities that enable you to fine-tune your HVAC system to your specifications. The majority of wireless smart thermostats allow you to program your furnace and air conditioner to operate at specific hours or in reaction to temperature changes. If you must reprogram these settings every day, they will not be very beneficial to you.

Occasionally, a malfunctioning thermostat will have trouble preserving the settings that the homeowner has selected. This might be caused by anything as simple as a dead battery or something more severe, such as a memory fault in the thermostat. If the issue persists, reset the thermostat to factory settings per the manufacturer’s recommendations. If you continue to be unable to save your changes, this is likely a hardware issue. 

  • Cycle Problems

In the central heating, ventilation, and air conditioning system, the furnace, air conditioner, and fan rely on signals from the thermostat to start and stop. When your thermostat fails or displays false temps, your HVAC system will not operate at the correct times.

Short cycling occurs when a defective thermostat causes the HVAC system to operate for extremely brief periods of time before turning off. Alternately, if the thermostat never transmits the shut-off signal, your furnace or air conditioner may operate continually.

To diagnose cycle difficulties, time how long your system operates at your regular temperature before switching off. A professional should evaluate your thermostat and maybe the remainder of your system if they run duration is less than ten minutes or greater than an hour. 


In our energy-conscious culture, wireless smart Thermostats are one approach to cutting your energy use and utility bills. The HVAC systems of tech-savvy households may be programmed for maximum comfort and efficiency. 

The environment in your house is the largest element in determining your day-to-day comfort. Wireless smart thermostats are an excellent choice for keeping a pleasant atmosphere with no effort.
