"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."

FAQs for humidifier repair projects in Keller, TX

If your refrigerator needs to be repaired, contact an appliance repair company to diagnose the issue and repair your refrigerator. It’s okay to leave it plugged in and running, but unplug it if it makes unusual noises.

Signs that your refrigerator may need repairs include:

  • Food items are not being held at the correct temperature (between 35 and 38 degrees Fahrenheit)

  • The fridge is using too much energy and seems to run all the time

  • Loud and/or unusual noises

Possible causes include:

  • A damaged door 

  • Faulty condenser coil 

  • Malfunctioning control board

Contacting an appliance repair professional as soon as possible can help save items in your fridge from spoiling. Common fridge repairs include the compressor, control board, thermostat, defrost motor, coils, and ice maker.

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost to repair an appliance depends on the appliance, make, model, the part that needs repair, and how long it takes to replace or repair a part. The following are the average repair costs for the most common appliances:

  • Refrigerator: $200–$300

  • Freezer: $90–$500

  • Oven, cooktop, range: $100–$500

  • Microwave: $50–$400

  • Dishwasher: $160–$300

  • Garbage disposal: $70–$250

  • Washing machine: $50–$450

  • Dryer: $100–$400

Appliance repair contractors may charge $40 to $120 per hour for labor, and most also provide the replacement parts necessary at an additional cost.  It’s also important to note that these prices can go up on holidays and emergency fees may apply if you need your appliance fixed immediately.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
