"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."

Central humidifier installations and replacements FAQs
Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.
With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.
It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.
Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.
If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
