Not Sure If You Should Repair or Replace Your AC?

Deciding between an AC repair and a full replacement can be tough. At Michiana Mechanical, we make it simple. Our experts will assess your system, clearly explain your options, and help you choose the most cost-effective and energy-efficient solution for your home.

Whether your AC is failing to cool, leaking refrigerant, or causing your energy bills to spike, we’ll help you make the smart call.

Common Air Conditioning Problems We Fix

We diagnose and repair a wide range of AC issues for homeowners throughout Northwest Indiana and Southwest Michigan.

Warm Air Blowing from Vents

If your system runs but does not cool, we’ll check refrigerant levels, compressors, and coils.

AC Unit Cycles On and Off

Frequent cycling can strain your system. We’ll inspect sensors, thermostats, and airflow restrictions.

Weak or No Airflow

If your home is not cooling evenly, your blower motor, filters, or ductwork may be to blame.

Strange Noises or Odors

Buzzing, rattling, or musty smells often signal electrical or moisture-related issues.

Water Leaks Around the Unit

Pooling water can indicate a clogged drain line or a frozen evaporator coil.

High Energy Bills with No Explanation

If your utility bills are climbing, we’ll check for inefficiencies or worn-out components.

Recently, Ayden completed routine maintenance, and he did an excellent, efficient job. As with all of MM’s employees, he is courteous and took the time to answer my questions so that I could understand the system and its capabilities. Our home is so comfortable, with no hot or cold spots. Very happy with Michiana Mechanical.

I just had Edgar G complete my summer maintenance on my Daiken air conditioner and replace my furnace filter. He is friendly, professional, and courteous. I’m very happy with my Daikin furnace and air conditioner system and Michiana Mechanical.
