Why Is My Thermostat Draining Batteries?

Las Vegas, NV, Thermostat Maintenance

The minute homeowners start noticing inconsistencies in their home temperatures, they usually assume the whole HVAC system is on the fritz. But sometimes, a nonresponsive thermostat is just that: nonresponsive. Your expensive heating and air conditioning systems are only as good as the thermostat that detects and sets the room temperature. If you have a digital wall unit that’s starting to fade or flash, the batteries are impacting the efficiency of your whole heating and cooling system.

Thermostats can be hard-wired or battery-operated, but even battery-powered models should work for several months to a year or more without new batteries. If you’re replacing batteries in your thermostat unit as often as once a month, that’s not normal for most systems and you should give our team a call.

Why thermostats can drain batteries

The simplest answer is also the most likely: The thermostat is old or just faulty. The temperature settings you program into a digital wall thermostat don’t impact battery usage (e.g., turning down the air conditioning in the summer won’t save the battery life of your thermostat; you’ll just save on your energy bills). Since there’s not much in terms of usage that causes the problem, it’s most likely a problem with the type of battery or with the unit itself.

Checking the batteries

First, check to make sure the batteries are, in fact, dead. Depending on the exact thermostat model, you should see a battery compartment on the side, back, or underneath a sliding panel with space for two or more AA or AAA batteries. Most thermostats are not compatible with rechargeable batteries, which don’t deliver the right voltage, so stick to single-use options.
Once removed, test them in another device to make sure it’s the batteries that are draining and it’s not a problem with the thermostat unit’s ability to connect and draw power. Even if the screen on a digital thermostat fades or a “replace battery” light comes on, that’s not a sure sign the battery is dead, only that the wall unit isn’t getting enough power. Non-lithium batteries may also drain faster, so make sure you’re using a quality, brand-name lithium battery to ensure the longest life.

If the problem is with the wall unit, either because it can’t get enough power from good batteries or it’s draining them unusually fast, it’s normally not very cost-effective to repair the small thermostat. Instead, it’s easier to replace the wall thermostat with a new unit and see if the charge holds longer. Sometimes, the thermostat will be covered by a manufacturer’s warranty (Honeywell is one of the most common brands) or by your builder’s warranty and/or homeowner’s insurance. Yes! Air Conditioning & Plumbing can replace the unit with the same kind or take the opportunity to upgrade the model while we’re at it.

Why we love the Nest thermostat and smart home products

If you decide it’s time to upgrade from a battery-powered digital thermostat that’s draining AAs at a blinding speed, you have a great opportunity to opt for a programmable or even smart home thermostat to help minimize energy usage.

The reason Yes! Air Conditioning & Plumbing loves to recommend the Nest thermostat is because we’re committed to 100% satisfaction for our customers and exceptional service. If there’s one product we’re most confident about delivering on these promises, it’s the easy-to-use Nest system. You don’t need to rewire your whole house, and the Nest thermostat works with 95 percent of low-voltage (also called 24-volt) heating and cooling systems used with furnaces and central HVAC systems that are common around Las Vegas.

A smart thermostat like Nest learns without being laboriously programmed when you’re most likely to be home and what temperatures you prefer throughout a given day or season, adjusting automatically or via your command over a Wi-Fi connection to keep you comfortable without running unnecessarily while you’re away. As a result, you can save anywhere between 10 and 15 percent on your heating and cooling expenses, making it a great upgrade option if your current thermostat is costing a small fortune in fresh batteries alone.
