Thermostat Not Wokring? 3 Common Causes & SolutionsIt’s finally starting to feel like summer, and the outdoor heat will soon be on.

While many of us are looking forwad to warmer termperatures, many of us prefer to keep things cool inside our homes. However, a malfunctioning or not-so-efficient thermostat can’t exactly help offer relief from the heat.

If your thermostat isn’t working, take a look at these common causes and solutions for each.

1. Dirt & grime build-up

Yes, your thermostat can be affected by dirt, dust, and grime after years of use. Depending on the type of thermostat you have, dust can accumulate in the vents and block airflow and temperature detection, or on the double-metal spin arm which reduces its reactivity to changes.

Remove the thermostat cover and clean out the dust each season. If you can’t or don’t feel comfortable exposing the inner workings of your thermostat, using a can of compressed air to blow through the vents is also a good option. If you go this route, however, make sure that your thermostat is turned as off as you can make it, and expect not to turn it back on for at least an hour afterwards. (Compressed air introduces an artificial cooling effect on the electronics of the thermostat. Use sparingly and in short, controlled bursts).

2. Less-than-ideal thermostat location

Generally, you can’t really control the location of your thermostat, however, it is a potential problem.

Ideally, the thermostat should be in a location in your home where the ambient temperature is least affected by your HVAC system or heater, so if you can move it, keep it away from vents, ducts, windows, and any heat or cold generated appliances.

If that isn’t an option, replacing your thermostat with a newer model that regulates temperature from the same location, but has moveable sensors in other locations – such as the Honeywell Prestige IAQ – may the best approach. Contact Pronto to schedule an appointment with a thermostat expert, who can help determine an optimal model for your home and HVAC system.

3. Extreme use/old age

Thermostats are subject to normal wear and tear just like anything else in your home and are not designed to last forever. If you have a thermostat that’s more than 20 years old, it may be on its last legs already.

Replacing your thermostat is crucial under these conditions, but it’s also a good idea whenever your home goes through a major renovation. Many older thermostats rely on mechanical processes to detect the current temperature, and those parts do wear down over time. Investing in a newer model can also significantly improve energy efficiency, which means lower utility bills as well.
