"Mansfield Plumbing charges $69 to come do an estimate. They say they can't give estimate on phone because each house is unique. The price they charged however is not individually made. They charged $489 to install my Kitchen faucet that I bought. Only labor for less than 1 hour. I called them to get a break down of how it cost $489 for installation of a faucet and they didn't call me back. I will never use them again."

We offer fast, reliable air conditioning repair and replacement in Dallas, TX. We are also licensed plumbing and electrical experts. At Xtreme Air Services, we believe in doing right by our customers. That’s why all of our work comes backed by our 100% satisfaction guarantee. We also don’t charge extra for service on nights or weekends. Work with a team that is dedicated to treating you like family. Xtreme Air Services is the leader in HVAC, plumbing, and electrical service in the Dallas-Fort Worth Metroplex. Call Today, Service Today!

"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."

"AAC is not just a family business, it's the family! They contacted me right away after my search on Angi to set up an appointment. Joe (the son) came out the next day and knew exactly what was wrong with our "vintage" 6-burner Viking cooktop (4 of the burners would not ignite). He ordered the parts and came back with his father, Don (the co-owner with his brother), and they fixed it. Since we moved into the house 15 years ago, 2 of the burners never ignited and a previous repairman had no idea what was wrong. Joe is super knowledgeable about various kitchen appliances, having worked for several different companies over the years. He was nice, helpful and professional. I am very pleased and highly recommend AAC! I would definitely use their services again. "

"We had to have a new hvac system installed. 05/22 We bought a Daikin system. We also had a duct cleaning performed, an air scrubber installed, & a new damper system put in. We also signed up for the quarterly service. 06/23 During quarterly maintenance, tech informs us of poor air quality and tells us we need a duct cleaning. I said we just had one done a year ago. The next day Chad (service manager) comes out and looks at it and says the tech had faulty equipment. 08/23 The discharge thermistors were faulty, the fuses tested weak, and the compressor was bad. There was an issue with how the system was installed. They replaced the parts all under warranty. It took around two weeks. They provided 2 window units at no charge. 06/24 Upstairs was not cooling, tech came out and the damper needs replaced, it was under warranty & was replaced the next day. The techs that come out have all been very polite, respectful, and efficient. They will charge a service fee anytime they come out for anything, even if itâ s under warranty. The manager Phillip came out and spoke with me personally about some of the issues I had. Honestly an HVAC system in Texas is going to be a pain in the butt. Overall Minuteman is one of the best HVAC companies around to help you deal with that."

FAQs for central a/c service or repair projects in Crowley, TX

A condenser fan motor is a crucial part of your air conditioner that prevents the compressor from overheating. It pulls heat from your AC unit to cool the refrigerant moving through the condenser coils. This allows your system to blow cool air and keeps everything running smoothly.

The most common causes of AC fan motor failure include loss of lubricant in the system due to overheating and a rusted or leaking run capacitor. Poor lubrication can also cause failure in the belt drive, which may impact the AC fan motor. Weather and electrical components can also affect your AC. For example, a storm could send water into your motor windings and damage the internal components.

Air conditioner fan motors last about 12 years on average, though they can last longer if maintained well. This includes keeping them clean and cooled as needed with annual air conditioner checkups. Routine maintenance is essential to catch AC fan issues early. An HVAC inspection can cost between $70 and $500, while AC cleaning services may range from $100 to $400.

A broken AC fan motor may need replacement because this part usually can’t be repaired. Several things indicate it’s time to replace your AC fan motor, including buzzing noises, a constantly running fan, unusually high energy bills, or an aging system. If you notice these signs, call an HVAC pro for help before the faulty motor starts to strain other parts of the AC system.

There are clear warning signs of a bad AC fan motor, including unusual interruptions in the fan operation. The motor might be malfunctioning if you hear weird noises like grinding or rattling or if the fan continues to spin when the unit is off. These indicators compromise your AC’s cooling performance and increase your energy costs. Addressing these issues immediately by contacting a trusted HVAC professional prevents further damage and safeguards your HVAC's efficiency.

Replacing your AC fan motor takes a professional one to four hours. The technician will start by assessing your system and safely removing the damaged motor. If a new part needs to be ordered, it might take a few days. Once the part is available, your pro will install it properly and make sure your system is running smoothly.
