Frequently Asked Questions
Why does my thermostat show a different temperature than the room feels?
Your thermostat might be positioned near drafts, or sunlight, or heat sources, which throw off its readings. Make sure it’s installed centrally, out of direct sunlight or vents.
Can a dirty air filter affect my thermostat’s performance?
Yes, a clogged filter can restrict airflow, causing your thermostat to miss its target. Change filters to help your system work efficiently.
How do I know if my thermostat is broken?
If your thermostat doesn’t react to adjustments or its display is empty, it’s possible that it’s defective. Attempt to replace the batteries or reboot it. If problems continue, see a pro.
Could poor insulation cause my home not to reach the set temperature?
Yes, bad insulation allows heat to leave in the winter and come in during the summer. This is what’s causing your thermostat to never reach the set temperature. Think insulation for comfort.
Does the age of my heating or cooling system matter?
Your thermostat isn’t reaching the set temperature. Service or replacement with a new system makes it better.
What should I do if my thermostat is not reaching the set temperature?
First, verify your thermostat settings, power and air filter. If issues persist, have a licensed technician check out your system!
Can thermostat placement affect its accuracy?
Yes, improper placement—too close to windows, doors or vents—can result in erroneous readings. Place your thermostat in a central, inside location for optimal performance.
