No! If you have the tools required, you should be able to replace a thermostat yourself. There are instructions with the new thermostat that will tell you exactly how to do it but if you don't feel comfortable doing it yourself, you can hire a local handyman, HVAC tech or electrician.
The cost to install a thermostat is $182 on average, but you could pay between $113 and $264. Thermostats play an important role in our daily lives, cooling us down during the sweltering summer heat and keeping us warm and cozy during winter. While the average cost to install a thermostat is $182, pricing can vary.
So, can a bad thermostat cause your AC not to cool? Absolutely. While it may seem like a small part of your HVAC system, the thermostat plays a crucial role in ensuring your home stays cool and comfortable.
A malfunctioning thermostat has a harder time maintaining a setting, and may quickly shift temperature settings with no warning. If your central air has a difficult time maintaining the set temperature, even after lowering a setting for a test trial, it could be the thermostat.
Switch the thermostat to the off position. Locate the breaker that powers your HVAC system and turn it off. Wait 30 seconds and turn the breaker back on. Turn your thermostat back on and confirm it has reset properly.
Your thermostat instruction manual can tell you exactly how to change a thermostat. Installing the thermostat yourself is an easy task that will typically take about an hour from start to finish.
There are a number of reasons why your AC unit may stop working unexpectedly, including electrical problems, blockages, thermostat issues, and more. Troubleshooting includes checking your circuit breakers, thermostat settings, and replacing your air filters.
Your thermostat reads the temperature of the room, then sends an on or off signal to the air conditioner. The AC itself isn't detecting the temperature in your home, so it has to rely on the thermostat.
You can typically just replace the outdated thermostat with a new thermostat – assuming the latter is compatible with your HVAC system. There are a few things you should know, however, when upgrading your thermostat.
Replacing your thermostat when you install a new AC system is a great idea. The connection between the thermostat and AC is important to the function of the system. Problems with the thermostat can cause the AC to run more often than it should or not as often as it should.
If your wires are connected but your thermostat still isn't working properly, that means it's time to hire a professional. They'll open the thermostat and test the wires individually to see which one is faulty. Since messing with wires is dangerous, you'll want to contact a certified HVAC technician.
Yes, many smart thermostats are designed for DIY installation, and manufacturers typically provide step-by-step guides and videos. However, if your HVAC system is older or lacks proper wiring (like a C-wire), the installation might become more complex, and you may need professional help.
Clean the Thermostat
Sometimes, when the room temperature doesn't match the thermostat setting, the problem could be dirt buildup on its interior parts. A dirt coating around the inner components may create excess heat and cause the thermostat to give the wrong readings.
The average cost of a new thermostat, including installation, ranges in price from $50 to $500 or more based on several factors including the type of thermostat, labor costs, the complexity of the installation, and more.
A bad thermostat can be detected when your AC or furnace is not turning on, your HVAC systems are not turning off, the thermostat not responding, your HVAC system is short-cycling, the room temperature not matching the temperature displayed on the thermostat, and the programmed setting resetting themselves.
In most cases, installing a new thermostat is a relatively simple do-it-yourself project that can result in improved comfort and convenience and one that can help you save energy.
The heating, ventilation, and air conditioning (HVAC) system in your home is controlled by your thermostat. If your thermostat isn't working, your furnace, whole-house fan, and AC unit are probably not functioning correctly, either.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
In AC systems, the air conditioner reset button is on the outside unit's lower edge, typically close to the ground. Some models have the reset button located behind the service panel, which may require tools to remove. Reset buttons are usually red or yellow with a clear “reset” label.
Any time you are having an issue with heating and cooling units, such as after a sudden power failure or after your children have had 'control' of the system while you've been away, resetting the thermostat should be the first thing you try when attempting to rectify HVAC system issues.
HVAC repair pros are a good option if you're looking for someone to replace a thermostat. In fact, you may find that many thermostat installers work with an HVAC company. Plus, by hiring an HVAC expert to replace your thermostat, you can also book an HVAC inspection at the same time.
