Home thermostats are manufactured to have a high level of reliability and efficiency as they control the temperature in a home. Each season, most residents heavily rely on the device to ensure they can remain comfortable in their home and feel more at ease. As a homeowner, it's important to know if thermostats can go bad and the most common issues that can start to occur.

Inaccurate Temperature Readings

You may find that your thermostat temperature doesn't seem to match the temperature in your home. Even as you adjust the temperature, the HVAC system may fail to make your home as cool or as warm as you desire. A professional technician will need to inspect the parts to determine if the issue can be repaired or if the product needs to be replaced.

The temperature may also fluctuate at random times and doesn't remain stable after you programmed it. This can lead to a higher energy bill that can prevent the home from feeling comfortable. If you have a mechanical thermostat, remove the cover and gently dust, and clean the parts to remove dirt and grime accumulated, which can affect the reliability of the device.

The Thermostat Unexpectedly Stop Working

You may approach your thermostat to adjust the temperature and find that the screen is entirely blank. If a thermostat has reached the end of its lifespan, it can unexpectedly shut off and fail to operate. If you own a mechanical thermostat, try replacing the batteries to determine if it restores its operation and allows the screen to light back up. If the thermostat still won't turn on, it's time to hire a technician to inspect it.

The Heater Won't Turn On

You may also notice that the heater won't turn on after several minutes of adjusting the thermostat. This is often due to a wiring defect that prevents electrical signals from transferring to the HVAC system. Consider removing the cover on the thermostat to adjust the wires and check to see that everything is connected to each mounting screw.

The HVAC system may also continue to run and fail to turn off after adjusting the settings. Try to turn the thermostat up or down five degrees before hearing a click. Wait five minutes before checking the supply registers to determine if any air is blowing out air. If the problem continues, contact a local technician to perform an inspection.

Proof We’re the Best HVAC Company Straight From Our Customers

Didn’t Push a Furnace Replacement

Taylor D.

Tom, the owner was awesome. He came out immediately when our furnace went out and completed a challenging fix. When I asked if I should replace the furnace he said no. Honest and did outstanding work. Furnace is quieter and seems to be running better than when we moved in!
Highly Recommended for AC Replacement

Jeremiah D.

Tom came over and thoroughly discussed my options. We discussed at length the pros and cons of the most expensive and least expensive options, and came up with a fair price for the products I chose. The crew showed up on time and finished the same day, and was easy to deal with. The new furnace heats my house so much better than the old one. I would definitely use Master Mechanical again. And I have. I’ve now replaced multiple furnaces and AC units using Tom and his crew at Master Mechanical, and would use them again.
Quick AC Fix During a Power Surge

Jim P.

Master Mechanical responded quickly when our AC failed following a power surge. They quickly diagnosed the problem, and responded patiently to my uninformed consumer questions. Once the team arrived to complete the repair work, they were professional and again, knowledgeable. Prices were fair, and they followed up with me after work was completed. Overall a great company!

Two Great HVAC Experiences

Bill L.

Did an excellent job on two repairs. The first was an emergency call for a furnace repair when it was 4 degrees F outside. They showed up on time, diagnosed the problem, went for parts, repaired the furnace all in about an hours time. The second repair was for the whole house humidifier attached to the furnace. It was a minor issue and corrected in less than 40 minutes. Everything is working great. My experience with their work is excellent.
