Since 1953, Dring Air Conditioning & Heating has been known for providing quality HVAC services in Carrollton, TX. Our team aims to keep your home comfortable year-round. We offer exceptional comfort services to our friends and neighbors in the tri-county area. We are a family-owned and operated business going back several generations. Our mission is to provide better air quality and comfort to what’s most important, your family. We are the oldest service company in the Dallas area and are proud to have maintained our core values. Because HVAC emergencies don’t happen on a schedule, we offer same-day and 24/7 emergency service repairs when you need them the most. Dring Air Conditioning & Heating is an industry leader that operates on old-fashioned values you can trust.

"I called Dring AC for a $70 "ac summer tuneup." The only reason I even called them was because they bought out the company that originally installed and maintained my origian AC, SunAir. At the time my AC was working without any issues. Dring came out on July 7 for the tuneup. He looked at the system and said there were parts that needed to be replaced. I specifically told him that I was did not want any repairs done because it was working fine and I asked for an estimate for replacement. He called a sales rep to come give me an estimate for replacement. While speaking with the sales rep, the tech said "I'm just going to replace your contactor to keep you running." which I did not authorize him to do. The contactor was one of the parts he claimed needed to be repaired, however I had already told him that I did not want any repairs done because the ac was already running fine. Then the tech came back inside and said after he changed the contactor, the capacitator blew. He then went to replace the capacitator, and a second one blew. Now I'm left with an ac that no longer worked, and according to Dring, was now unrepairable. This entire interaction is all on video, down to the last word, thanks to my home security system which covers both the interior and exterior of my house. At this point it's late on a Friday afternoon, my ac is out, its over 100 degrees outside and I have a pregnant wife and 3 pets living in the house. I had no choice but to move forward with having them replace the ac and was denied any opportunity to do my research or get quotes from other companies for replacing the system. On July 8, they came to replace the system. System was replaced, however, they were supposed to rerun the duct from the ac to the master bedroom and did not do so, despite that being one of my primary initial concerns not to mention was specifically told they would do that during the installation. They also took my $200 Nest thermostat and left a huge mess in the attic. When they "finished" the installation, I was handed an ipad to sign that didn't show me anything other than to sign. I received zero paperwork from the company at any point in time, not even for the loan I had to take out to pay for the replacement. Infuriated, I started to call other companies to get quotes and discovered I was SIGNIFICANTLY overcharged for the replacement system by almost double what it should have cost, literally thousands of dollars. Additionally, I have to find another company to come resolve the duct issue that Dring was supposed to complete and replace my Nest. I was also charged an additional $1k for service to clean all the hvac ducts, except when the duct cleaning company came, they informed me that there was no reason to clean the ducts since a majority of them had just been replaced. After filing a complaint with the BBB, the issue was considered to be resolved upon someone from Dring calling me and leaving one voicemail and then never returning my return calls. Not only was Dring's service reprehensible, it should be criminal to get away with the price gouging that they use. There's no better evidence for this tactic than their pricing timeline structure. Although it is commonplace for companies to use price incentives to encourage a purchase sooner rather than later, the sheer gap between their price for "today" vs one week vs one month, a gap of more than $10k, is just proof of how much they are padding their profits, all at the consumer's expense. At the end of the day, it is absolutely egregious for a company to come in for a tune-up, literally break your AC that was working when they arrived, and the extremely gouge you on the price of replacement. It's beyond egregious. I would NEVER let DRING touch my hvac unit EVER again. You've been warned."

"Here's a more refined, less repetitive version that maintains the same level of frustration and negativity: WARNING: Read Before Hiring Xtreme Air Services If you're considering Xtreme Air Services, take a moment to read this--there's a treat at the end. Surprise, surprise... yet another negative review. Let's start with Eddy O., the so-called "General Manager." Our Experience Eddy made it clear that Xtreme Air Services "wouldn't be able to help us" if we posted negative reviews about their incompetence, despite the fact that they improperly installed our unit, left us with a potential fire hazard, and disabled one of our heat coils (without our consent). Screenshot attached. After leaving us with a heater that doesn't function properly in winter, their solution? Pay thousands more if we want them to "help." Comical. So, in order to get the service we already paid for, we have to stay quiet? Oops. A Few Key Points: 1. Threatening not to help the customer with an issue you created? That's just ignorant. Zero integrity. 2. Why would we pay more to an unprofessional company that sends unqualified, non-bonded, non-insured workers to botch an installation? Rude, unaccountable, and incompetent from top to bottom. 3. This experience makes spending our money elsewhere EASY. The CEO is an imbecile. We paid over $12K for a unit that now operates on half power because the breaker they installed can't handle it. A professional company would've caught this--Xtreme Air Services didn't. Even their own seventh technician admitted, within seconds, that it was installed incorrectly. Still not convinced? Let's Talk Fire Hazards Both the Xtreme Air Services technician AND a third-party electrician confirmed our system was a fire hazard. Eddy (who is not a licensed electrician) claimed it wasn't because "that's why the breaker trips." That's not how fire hazards work, Eddy. This system was installed in the summer. Clearly, not one of the seven techs they sent even tested the heating function beyond a few moments. Fast forward to winter--our heater trips the breaker after 5-10 minutes, sometimes running inconsistently (aka, a fire hazard). Xtreme Air's Response? * No accountability. * No apology. * Just more incompetence from "General Manager" Eddy, a pompous clown who lacks both professionalism and basic customer service skills. Instead of addressing their negligence, he condescended, interrupted, and dismissed legitimate concerns. He even had the audacity to tell me we "don't have that many cold days in Texas." What does that have to do with selling and installing a properly functioning heating system? The real kicker? Their own sales team KNEW this system wouldn't work. They either failed to test it or outright lied. Either way, we now have a fire hazard and an unusable heater unless we fork over an additional $2,500-$3,000. Xtreme Air Services is an unprofessional, dishonest company that cuts corners and are a JOKE professionally."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
