Your Thermostat’s Temperature Readings Are Wrong

Is your thermostat in a poor location?

If your thermostat is set to a comfortable 72 degrees, but you spend hours feeling too hot, it could mean that your thermostat isn't reading the ambient temperature correctly. Or maybe getting the right temperature has always been a struggle, so you might need to move its location to get optimal control. After all, if the thermostat is in a spot often hit by drafts or cool air from entryways, its incorrect readings might not have much to do with your actual home temperature or your thermostat's function.

The Department of Energy estimates that you could save as much as 10% on heating just by programming your thermostat to deliver heat on a schedule. However, this only works if it properly responds to changes made to its settings.

While many homes have programmable thermostats, only 1 in 3 homeowners program temperature settings and usage times, according to the U.S. Energy Information Administration.

Upgrading to a smart thermostat is a great way to avoid similar issues in the future, as it will notify you when it needs battery or air filter replacements. Plus, smart thermostats bypass the need for programming because it automatically learns about your standard usage and adjusts the temperature for optimal performance, saving you money on heating costs.

How To Fix

When changing the temperature setting on your thermostat doesn't seem to do much to change the ambient temperature, it's time to troubleshoot before you call in the experts at Thornton & Grooms. Start by checking the thermostat’s battery to see if it’s fully charged. Many of them have both a hardwired connection and a battery.

Also, take a moment to change out your air filters if you haven't already. Clogged air filters can make it difficult for your thermostat to adjust your home’s temperature. Insufficient airflow means your HVAC system can't meet your set temperature.

If those two basic checks don't deliver results, it's time to consult our professional technicians for a replacement thermostat. Older thermostats may rely on mercury thermometers which need leveling for optimal performance, while newer thermostats could have a bad sensor. Our comfort specialists can quickly determine what issue is causing the malfunction and recommend the most cost-effective solution.

Your Thermostat Needs Electrical Wiring Repairs

Your thermostat may have faulty wiring.

As thermostats age, they can have problems with the wiring that communicates between them and the HVAC unit. Pests like mice can chew on wiring, and power surges can also cause significant damage to thermostat wiring.

No matter what caused the issue, you'll want to call an expert to restore your thermostat’s function. Working with electrical wiring is a job for a professional.

How To Fix

Generally, bad electrical wiring needs replacement. If the broken wiring doesn't directly connect to the thermostat, you can keep your existing unit after repairing it. However, if the damage is near the connectors for the thermostat, you'll likely need to replace it. Faulty wires leading into the thermostat could also damage its delicate electronics.

Your Heating System Is Malfunctioning

Is your furnace continually running?

What if the heating system keeps running non-stop after you check the thermostat? The problem is most likely your furnace or boiler. While too much heat is better than not enough when powering through a Michigan winter, neither option is desired.

If you've done the basic troubleshooting for your thermostat and think the problem might be with your unit, it's time to contact Thornton & Grooms for fast, reliable boiler, furnace, and thermostat repairs.

How To Fix

A fix for a malfunctioning heating system depends on what exactly is causing the problem. If your heat keeps running even after you shut off the thermostat, it could have a broken primary controller. The controller handles on/off operations, so a failure could have the heat running no matter what temperature you set.

Thornton & Grooms can perform comprehensive diagnostics as part of our furnace and boiler repairs to check for problems.
