How To Fix Common HVAC Thermostat Problems?

Your HVAC system is supposed to keep your house comfortable during extreme weather conditions. This means it should be running at its optimum at all times. But HVAC systems are also prone to problems like other electronic appliances. One of the most common problems is thermostat issues. If the thermostat is malfunctioning, the unit will not be able to maintain or achieve the desired temperature. This could be a frustrating problem to solve and you may have to call in air conditioner repair services. Here are a few tips that will help you get your thermostat and HVAC system running back to normal.

The Thermostat Screen Is Blank

Modern smart thermostats come with a display or screen that shows the temperature and other relevant information. If you come across a blank thermostat screen, you should not panic. It could be a simple problem, such as the batteries needing replacement. Replace the batteries or restart the thermostat to fix the issue.

If the thermostat does not have batteries and is directly connected to the unit via wires, you will need to access it and check for any cracks or damage. Make sure to turn off the unit before you inspect the wires. Sometimes, rodents and other intruders during the winter season tend to take up accommodation in search of warm areas and end up chewing the wires.

If that does not fix the issue, you will need to check the circuit breaker. The circuit breaker should be in the “On” position. However, if it is on and there is still no power, check for a blown fuse. Try replacing the fuse and switching on the circuit breaker to see if that solves the issue.

The HVAC System Does Not Turn On

The HVAC system itself not turning on can be a seriously frustrating issue. The reason is that there could be a lot of potential causes that could be causing the issue. But your HVAC system not turning on could also be due to a thermostat problem. Then again, it could be faulty wiring or circuitry.

You should keep in mind that modern HVAC units are loaded with safety features as well. So, if there is any risk of the unit experiencing damage, the safety feature will kick in and prevent the unit from turning on. In such a case, the thermostat will simply stop communicating with the unit

If you want to diagnose the issue on your own, make sure you have the skills, tools, and knowledge. Otherwise, you should contact an expert who will handle the issue without causing any damage to other components.

The HVAC System Runs Constantly

If the HVAC system runs nonstop without tripping even after achieving the desired temperature, it could be a thermostat problem. You can try turning the thermostat off. If the HVAC system continues to run, it means the thermostat is faulty and not communicating with the unit properly.

In such a case, the thermostat’s wiring will need replacement or recalibration. For this, you will need to consult an HVAC expert and the good news is that it should not be a major fix that will be heavy on the pocket. However, you should get it fixed ASAP because this issue can lead to compressor problems.

The HVAC System Is Short Cycling

An HVAC system short cycling is a tell-tale sign that the thermostat is experiencing issues. If you notice the HVAC system turning on and off continuously and is running for a very short period of time, it could be due to a thermostat issue. Although HVAC system short cycling could take place due to a variety of reasons but you should also consider thermostat issues.

You should check the air filter as well for any blockages. Try cleaning or replacing the filter to see if that fixes the issue. Otherwise, you will need to check the refrigerant as well. An HVAC system runs on a specific refrigerant level and if the level happens to be low, the system will short cycle.

You may not be able to check the refrigerant level on your own, as there could be a leakage as well. You will need to consult an expert who will use proper tools to find out the source and refill the refrigerant. Moreover, short cycling can also be caused if you have a bigger HVAC system than your house’s requirements.

Erratic Temperature Changes

A failing or malfunctioning thermostat will result in fluctuating temperatures throughout your home. Some areas might be cooler than the others and it could be due to the thermostat not being able to maintain the temperature. But keep in mind that other issues could also be causing this issue.

For instance, if the ductwork has leakages or blockages, you will feel some areas a lot cooler than the others, but it won’t be due to a problem with the thermostat. You will need to inspect the ductwork for any cracks or damage. It can be a tricky diagnosis and you should hire a AC repair services Huntington to fix it.

The Thermostat Shows Incorrect Temperature Readings

When the thermostat is working normally, it should show the correct temperature. An incorrect temperature indicates that the thermostat is facing an issue. If the HVAC system was recently serviced, it could be that it lost its calibration.

Even though you can calibrate the thermostat on your own if you have the tools and know the technique, it would be a lot better to consult an expert, as modern thermostats can be slightly tricky to work with.

The Thermostat Forgets Your Programmed Settings

If the thermostat of your HVAC system keeps forgetting the settings or reverts to another temperature setting, it may need calibrating or a software update. It does not necessarily mean the thermostat is bad. But if the HVAC unit happens to be old, it could be an indication that the thermostat might be failing as well.

You can consult the user manual to troubleshoot the issue, or there is always an option of contacting an expert.

The Unit Is Too Old

If nothing else works out, it could simply be that the unit is too old and needs replacement. Regardless of how well-maintained an HVAC system is, it will experience wear and tear and will eventually need replacement as the components turn weak with time.

At this point, it won’t be a smart move to spend on expensive repairs and replacements. Instead, you should save the money and invest it in a newer unit. This way, you will be able to save money on electricity bills as well since modern HVAC units are a lot more energy efficient.

Conclusion

Thermostat issues are mostly fixable. But you never know when you will face off with them. To prevent panicking, the above-mentioned tips will surely help you get down to the problem, if not fix it or hire HVAC repair services Smithtown. However, you should make sure the HVAC unit receives professional care and does not run into complications when you least expect it to.
