What To Check

If you believe that your thermostat is not functioning correctly, there are a few things that you should check first.

Check Your Batteries

However, these connections are there to control the system and not to power the thermostat. To check your batteries, remove the front of the thermostat and put new batteries in. If your HVAC starts functioning correctly, you have solved the problem.

Are You Experiencing A Brown-Out?

A less common cause of the problem is if the power supply to your home is bottlenecking or sort of impedance. This is also known as a brownout. Brownouts can cause your HVAC system to malfunction and it may not even be the thermostat. Before you have your thermostat repaired or replaced, you should make sure that there is no power issue in your home.

Check The Mode

It is essential that you check the mode that your thermostat is on. If someone in the house has accidentally switched the thermostat to cool rather than warm, you might think that your system or your thermostat is not working. Before you assume that your thermostat is malfunctioning, make sure that it is set to the correct mode.


Is Your System On?

This may sound like a dumb question. However, it happens more than you think. If your thermostat displays information all the time, even when it is set to off, you might not even realize it. If you are changing your thermostat settings, you should make it a habit of always being sure that the system is on.

What Is The Ideal Thermostat Setting?

Fan-Only Mode: Some thermostats have a fan-only mode. When this happens, the fan is the only component in the system that is working. It may sound like the unit is operating. However, it could just be that the system is blowing hot or cold air, depending on the season. You should never set your unit on “fan-only”. Instead, always keep it set to “auto.” This is a great way to keep your home comfortable while conserving energy.
The Thermometer Room Temperature and the Settings Don’t Match: If the interior of the thermostat gets dirty, it can give you an inaccurate reading. When this happens, you may think that the temperature in the room is not changing even though the system is on.

The tips above can help you diagnose the problem with your thermostat, and they can save you money. If you can figure out the problem, you won’t need to pay for a professional to come in and diagnose the issue. Some companies will charge you for a service call even for a battery change.
If none of the tips listed above have rectified your problem, there could be an issue with your HVAC system that needs to be inspected by a heating and cooling technician. If the problem is with your HVAC system, you should never try to fix it on your own. A DIY repair can make the problem worse. It is also dangerous to your home and your health.

If you want to work with the most trusted HVAC company in the area, give Lawes Company a call. We can diagnose your thermostat issue and install a new one if necessary.

As a side note, if you do need a replacement, it is a great time to switch to a smart thermostat or a wifi thermostat. Honeywell thermostats are an excellent choice. All of the features available on these thermostats make them well worth the money. If you aren’t sure if an upgrade will be beneficial or if you don’t know much about smart thermostats, one of our technicians can talk you through it. You can also check out thermostat reviews to narrow down your search.
