Service page

We have more than 30 years of experience

If it breaks down in the middle of summer, you can look forward to hot, sticky, humid conditions until it’s been repaired. Extreme temperatures can even be dangerous, especially to the elderly.

It’s important to have an experienced and trustworthy technician examine your system. Improper care like adding the wrong refrigerant, failing to fix a leak or making other errors can create even more problems. No matter what your AC needs are, we’ve got you covered. We provide everything from seasonal AC tune-ups to emergency air conditioning repairs for complete, state-of-the-art, energy efficient HVAC systems. We even provide low-cost monthly protection plans for your home’s systems to help safeguard your family and budget from unexpected emergency repairs or unplanned installations and replacements.

Turn to the professionalism and technical expertise of Missouri Heating & Cooling technicians to make sure the job is done right.

Air Conditioning Inspection and Diagnosis

Our HVAC experts will inspect your system, diagnose what went wrong and thoroughly explain what your options are.

There’s a variety of problems that can cause your air conditioner to not function properly. It could be that your thermostat or sensor is not working correctly, or the motor or compressor may have failed. A dirty filter or evaporator could also cause problems, or you might be low on refrigerant.

While we cannot know for sure what has caused your home’s air conditioning system to stop working, our technicians have identified the most common issues in AC repair jobs.

  •  Fan not working
  • Indoor coils have frozen
  • Malfunctioning thermostat
  • Musty, damp or high utility bills
  • System is short-cycling
  • System is not maintaining desired temperature
  • Leaky refrigerant or ductwork

Here at Missouri Heating & Cooling, we service all major AC brands and models. No matter what is wrong with your home’s air conditioning system, our technicians will thoroughly inspect your unit to make sure they completely understand the problem and provide an appropriate solution. Your complete satisfaction is our goal during the service.

Air Conditioner Replacement

A professional cleaning may get your unit back up and running, but you may need to replace a part, or it might make sense not to repair and consider replacing your air conditioner.
