Free Second Opinion

Before committing to a costly HVAC repair or replacement, homeowners in the Greater Cincinnati area should consider getting a free second opinion from Air Authority in Mason, Ohio. All too often, other companies pressure homeowners into full system replacements when a simple, affordable repair would do the job. And when replacement is truly necessary, quotes from local competitors frequently include inflated pricing and unnecessary add-ons that drive up the total cost. Air Authority has built a strong reputation for honesty and integrity by helping homeowners avoid these pitfalls—consistently saving them thousands of dollars by providing expert second opinions that cut through upselling and exaggeration. A second opinion from Air Authority isn’t just free—it’s smart peace of mind.


Award Winning

Air Authority proudly serves homeowners throughout North Cincinnati with industry-leading service, repair, and maintenance for home heating and cooling systems. As a locally owned and operated company, Air Authority brings unmatched integrity, reliability, and customer care to every job—qualities often missing from out-of-town HVAC providers or firms backed by large investment groups based in places like New York City. Homeowners are frequently surprised to learn that some companies claiming to be local are actually owned and operated far from the Greater Cincinnati region. Air Authority stands apart, not only through its deep local roots but also through its recognition by respected industry organizations like the NATE Association (North American Technician Excellence), Angie's List, and CincyBest.com. As active members of the Mason and Deerfield Chamber of Commerce and with an A+ rating from the Better Business Bureau, Air Authority is a proven, award-winning choice for trustworthy, high-quality HVAC care in Cincinnati.

Satisfaction Guaranteed

Your satisfaction begins with the little things. At Air Authority we want you to understand your HVAC issues before you make a decision. That’s why we offer a twice-a-year, multi-point performance and safety check that includes:

Check of capacitors, electrical connections, refrigerant levels

An evaluation with you about your system’s performance. We answer questions such as: Are any registers sweating? Is the system cooling as it should? Are there any unusual noises when it starts? Is your electric bill higher than normal? Is the temperature in rooms consistent?

  • Check for loose fan belts, a potentially serious issue
  • Evaluation of the HVAC unit’s physical condition
  • Airflow Test – “If you’re not testing you’re only guessing”
  • Condensing coil cleaning with the right equipment. Dirty coils decrease efficiency and increase costs. Clean condensing coils will save you dollars
  • Duct inspection
