Air Conditioner Experts


With high Metro East heat and humidity during the summer, your air conditioner can easily be stretched to its limit. But with proper maintenance and effective repairs, the Ehret team will make sure it’s operating at peak efficiency. Our comprehensive AC services will keep your cooling system strong and resilient all summer, come what may.

Preventive Air Conditioning Maintenance


Ehret’s seasonal AC tune-ups and preventive service agreements can virtually eliminate AC breakdowns. Why put yourself through the hassle of waiting for air conditioning repair on a hot and muggy day?

Studies show that preventive maintenance can reduce your energy costs by up to 40 percent. They also show a 95 percent reduction in air conditioning repairs with regular equipment servicing.


    Emergency 24/7 AC Repair


    Is your air conditioner in distress? Any unusual activity or noise on the part of your AC is cause for concern. Turn the unit off and call Ehret immediately.

    If you call us right away, we may be able to resolve the difficulty over the phone and save you an AC repair call. Running the unit when it has issues can quickly turn a small AC repair into a whole new air conditioning installation.

    Our certified technicians understand each step to take when your air conditioner is experiencing issues, and we’ll only finish the job when we feel confident your AC is fit to run again.
