Your HVAC system is one of the most essential systems in your home, but it requires care and maintenance if you want to keep it in good working order. The functions of your HVAC system are controlled by the thermostat, which is typically mounted on the wall somewhere in your house. However, there are a number of things that can go wrong with your thermostat, and they can have a major impact on your comfort. If you're experiencing a blank or malfunctioning thermostat display, read on to find out why and what you can do about it.

What causes a blank thermostat display?

There are a number of warning signs that something could be wrong with your thermostat. You may find yourself asking, "Why is my thermostat blank?" In some cases, it may just be that the thermostat is turned off or the batteries are dead. A tripped circuit breaker is another possible cause of a blank thermostat display. Once you adjust the misaligned switch, the thermostat should turn back on. Trapped dust and dirt could also be preventing your thermostat from working correctly. Some house cleaning is usually all that's needed to address the issue.

Changing the batteries in your thermostat or pressing the power button isn't complicated, but you may want professional help with other types of troubleshooting. When the cause of the problem isn't straightforward, you should call an HVAC technician as soon as possible. Trying to repair your thermostat yourself without proper training or tools can put both yourself and your home at risk of serious harm.

Proper maintenance is essential if you want to extend the life span of both your HVAC system and your thermostat. You should have the unit inspected at least once annually, though it's always best to have a professional look at it if you suspect something is wrong. Your HVAC filter should be changed at least once every 90 days, though experts recommend monthly filter changes for peak performance. Both HVAC systems and thermostats have a life span of about a decade, so if your system is older than that, you may want to think about a replacement.

How else can you control the temperature indoors?

A smart thermostat is a great investment for every homeowner. If you're experiencing problems with your current thermostat, you should consider an upgrade. Smart thermostats are Wi-Fi-enabled devices that are compatible with home automation and can be operated via a smart speaker, mobile phone, or web portal. Some thermostats even use an algorithm to learn from your behaviour and adjust your HVAC's schedule accordingly. A smart thermostat can provide you with more control over the indoor temperature and help you save money on your utility bills.

Keep in mind that there are also outside factors that can affect the temperature in your home. The condition of your windows can play a surprisingly large role in your comfort indoors. Cracks, crevices, and other imperfections can allow outdoor air to seep in, which will force your HVAC system to work harder to maintain your preferred temperature. This can cause a noticeable spike in your energy costs. You should ensure that cracks and crevices are caulked or filled if you want to get the most out of your heating and cooling system.

As you can see, there's a lot that goes into making sure your HVAC is operating at peak efficiency. Your thermostat can be particularly sensitive, so it's important that you inspect it frequently and address any problems immediately. Once you've checked for obvious issues, like dead batteries, you can call in a technician to help troubleshoot your thermostat. If you do need a replacement, consider upgrading to a programmable thermostat, which can maintain your desired temperature and cut down on your energy costs. The condition of your home can also affect the indoor temperature, so don't neglect maintenance and repair. No matter what the problem is, it's necessary that you get your thermostat working again quickly.
