Comprehensive Air Conditioner Repair Services

Your residential or commercial AC unit has three major components. When choosing an HVAC contractor for repairs, it’s crucial they have the knowledge, tools, and experience to diagnose and repair issues with each of the system’s components. Luckily, the professionals at Grissom Heat & Air have the right parts and tools to ensure your system is working correctly. When you choose us for repairs, our team will conduct a thorough inspection of the major components, including:

  • Mechanical – Over time, the mechanical parts within your AC system will begin to break down. Deterioration causes your system to run slowly and inefficiently.
  • Electrical – Your AC’s electrical systems power it. However, faulty electrical can prevent it from turning on, create a fire hazard, or make it run less efficiently.
  • Ductwork – The ductwork is the system that delivers the air conditioning through different parts of your property. Our team will identify air loss throughout the ductwork and inspect for excessive debris buildup.

Does My AC Need Maintenance or Repair?

You can always count on Grissom Heat & Air for reliable repair services. The best, most affordable way to ensure your system is working correctly is with yearly maintenance services. However, as a homeowner, it’s essential you’re aware of the warning signs that your AC unit isn’t working at maximum efficiency.


  • Uneven Cooling – Your AC unit should provide even cooling throughout your home. If you find that one room is comfortable while the other is sweltering, it could be an issue with your ductwork.
  • Rising Energy Costs – When you’re experiencing unexpected rising energy costs, it could be that your AC system isn’t running at peak efficiency.
  • Water – Your AC unit should never be leaking water. If you find water near your AC unit, it’s an indication there is a broken part.
