Troubleshoot Your Thermostat

Thermostats very seldom fail, and when they do it’s typically due to minor issues.  Of course, in time it can wear out and will require replacing. This article will assist you in checking your HVAC thermostat before you call your technician for repair.

The first step is to check the thermostat settings. The fan setting on the thermostat should be set to ‘Auto’, and the operation should be set to cool.  If this is not the case, make sure that your desired temperature is lower than the current room temperature reading. This may be all it takes to correct the problem. If that does not work, inspect the panel box and ensure the breaker has not flipped.

Smart thermostats aren’t immune from developing problems. Check for a low battery message or red blinking light. This may mean the thermostat is having difficulty connecting to the WIFI and can cause the AC system to not operate.

If you have opted to install a Smart Thermostat yourself you may want to reconsider that depending on the model you have selected. Proper installation is essential for the correct operation. That’s why it may be to your advantage to schedule the install by your HVAC technician. When working with electricity, it is always better to let a professional handle it.  Some of the problems you may encounter with a self installation include crossing wires and receiving heat for cold or cold for heat. Continuous rebooting is an another example. If you aren’t comfortable with the installation, trust your technician who will also explain its operation after installing.

Smart thermostats

As previously stated, the failure to connect to the WIFI in an established thermostat, may be due to a low battery level. Some Smart Thermostats have a wire to keep the battery charged or use a common wire. Problems can develop from these connections, especially if not properly installed.  Without a proper connection for charging the battery, problems will continue. Your Metro Express Service technician will determine the problem.

Types of Thermostats and Features of Each

Besides Smart thermostats, other types include programmable, non-programmable, and manual. Smart thermostats offer the greatest features and energy savings plus much more. Some can also “learn” your schedule, that’s an advantage if you don’t like programming a thermostat. They can be monitored and controlled when you are not even at home. This is thanks to the fact that it is able to connect to your home’s WIFI network and has internet access. Which allows you to use the internet to connect to your thermostat to monitor and/or change settings while away from home. All that you require is an internet connection and an included app.

Most of the latest models are voice activated, and compatible with Google Assistant and/or Amazon Alexa. An additional advantage is many more of them are easier to program than earlier models. Earlier features are still available such as email updates, monthly energy reports with suggestions for saving even more energy, and a vacation mode may be featured. If your schedule has you arriving home at various times, having the flexibility of a Smart Thermostat could serve you well. Resetting your thermostat remotely with a WIFI connection when your away can save you greatly on energy consumption.

Other handy features of some models include notifying you when a problem occurs with your HVAC system, or when someone in your home adjusts the temperature, for example. Smart thermostats offer flexibility and maximum savings for your busy and varied schedule.

Programmable Thermostats

A programmable thermostat provides you with the ability to preset temperature changes on a daily or weekly basis. This feature helps to conserve energy while you are away or sleeping, and ensures your comfort when you arrive home. They are available in with options of available settings, and you select the one that serves your typical daily or weekly schedule. Some models offer smart phone compatibility with a WIFI connection. This enables you to change your settings with your tablet or phone. If you tend to forget adjusting the thermostat while you’re away from home, or before bedtime, a programmable thermostat can ensure energy savings by controlling temperature according to the settings you program into it.

Manual Thermostats

Manual thermostats are the original mechanical ones, this means they are manually controlled. They are often known for their unreliable temperature fluctuations. They are neither digital or energy efficient. While fairly simple to install, if you are concerned with saving energy, a manual thermostat is not the best option. However, you are typically home and don’t mind adjusting the temperature, a manual thermostat is an inexpensive option.

Non-Programmable Digital Thermostats

A non-programmable digital thermostat is controlled with a manual digital display. They don’t offer smart technology or presetting, but are typically easy to read. While they are manually controlled, they typically offer reliable temperature control. If you select this type of thermostat, opt for a backlit display. That way if you forget to adjust the temperature before going to bed, you won’t have to turn the lights on to do so. The non-programmable digital thermostat offers a higher degree of temperature control than a manual thermostat. It offers an affordable choice for those who are home most of the time. They often operate on batteries, so keep extras for use.
