AC Thermostat Not Working: A Customer’s Tale

Hey there, it’s Russ or Peter from Reliable Appliance & HVAC. Today, we’re going to talk about a common AC problem – a thermostat that isn’t working.

Let me tell you about our recent call with a customer, Jane Smith, who lives in sunny Los Angeles, California. She has a central AC system made by the well-known brand, Goodman. One sweltering day, Jane turned her thermostat down in hopes of feeling a refreshing blast of cool air, but nothing happened. She tried fiddling with the settings, but the display remained stubbornly unchanged.

Frustrated, Jane called our hotline and described her problem to us. Our support team quickly diagnosed the issue as a faulty thermostat and dispatched a certified technician to her home.

John Doe, our technician, arrived at Jane’s home just two hours after her call. After greeting Jane and inspecting her AC system, John deduced that the thermostat’s wiring had been dislodged, causing it to malfunction. He meticulously ran diagnostics to make sure that no other factors were causing the problem.

After identifying the issue, John provided Jane with a detailed quote, summarizing the total cost of the repair. The quote included the cost of replacement parts, labor, and materials. Finally, our managers reviewed the quote, ensuring that it followed the manufacturer’s recommendations, and that we provided Jane with competitive pricing.

Here’s the full breakdown of Jane’s costs:

Description Cost
Thermostat Component $100
Deferred Life Labor $50
Travel Fee $25
Total Cost $175

When we provided Jane with this quote, she was quite surprised. “Wow, that’s even cheaper than the quote I received from another company!” exclaimed Jane. Our technician John beamed with pride when he heard that, as providing competitive pricing is at the core of Reliable’s philosophy.

After Jane gave us the go-ahead, John got to work, swiftly replacing the malfunctioning component. He made sure that the thermostat was clean and fully functional before testing the entire system. Finally, John gave Jane a tutorial on how to use her thermostat and answered all of her questions.

“I never realized how much I relied on my AC until it stopped working,” Jane admits, shaking her head. “But I’m so glad that I called Reliable. Your team was friendly, knowledgeable, and quick. I’m definitely going to recommend you guys to all of my friends and family.”

At Reliable, we know that a faulty thermostat is no small issue. That’s why we make sure that all of our technicians are fully certified and equipped with the latest knowledge and tools to get your AC back to working order as soon as possible.

The Preventive Actions to Avoid AC Thermostat Not Working Issues

AC thermostats are a crucial component in every AC unit. They help regulate the temperature and ensure your indoor space is comfortable. However, like any other device, they can malfunction, leading to discomfort and increased energy bills. To avoid such issues, here’s what reputable manufacturers, local appliance companies, and HVAC technicians recommend you can do;

Regular AC Servicing and Maintenance

It is best to have a professional HVAC technician check your AC unit regularly. They can perform routine maintenance on your AC system, which helps keep the AC thermostat functioning correctly. They check for any signs of wear and tear or corrosion in the wirings or connections, replace worn-out parts or clean any accumulated dirt or debris.

Install a Programmable Thermostat

Installing a programmable thermostat is an easy way to maintain your AC system’s efficiency. It allows for convenient scheduling of temperature changes, giving you better control over your indoor conditions. With a programmable thermostat, the AC unit can remain shut off when it doesn’t need to be on, ultimately extending its lifespan.

Keep the Thermostat Clean and Dust-free

The AC thermostat should be kept clean and dust-free as much as possible. Dust and dirt accumulation on the thermostat sensors can cause it to malfunction. A quick wipe-down with a soft cloth or cleaning brush can help keep your thermostat functioning correctly.

Replace Thermostat Batteries

Old or worn-out batteries in your AC thermostat can cause it to malfunction or shut off completely. It’s advisable to replace the batteries at least once a year to avoid such issues.

Upgrade to a Smart Thermostat

Smart thermostats come with advanced features such as Wi-Fi connectivity, voice control, and energy monitoring. They are designed to learn your preferences and adjust accordingly, ultimately improving energy efficiency and performance. Upgrading to a smart thermostat can be a long term solution to your AC thermostat not working issues.

In conclusion, AC thermostat not working issues are a common problem that many homeowners face. However, regular servicing, installation of programmable or smart thermostats, cleaning, and maintenance can minimize such issues. It’s imperative to have a reputable and professional HVAC company like Reliable Appliance & HVAC check your AC system regularly. Contact us today at (866) 516-1222 and let our experienced technicians keep your AC unit running efficiently.
