6 Warning Signs That Your HVAC Unit Needs Repairs

Sometimes it’s hard to know when to call the professionals to look at your HVAC unit. Not all the warning signs are apparent, but because the equipment is so expensive, repair professionals should be called to avoid costly repairs later on.

These warning signs often indicate some component or part is failing or under strain, and if caught early enough, can be fixed before severe damage to the equipment can occur. 

Common Commercial HVAC repair warning signs may include:

  1. Uneven Heating or Cooling Output
    • If you have spaces receiving uneven cooling, this is a sign that something is not quite right. It could be a blockage in the ductwork, motor problems, refrigerant leaks, or other components.
    • If your employees complain about one part of the building, it’s time to get an HVAC repair technician out. Blockages or other problems can cause the HVAC unit to work harder to cool those areas than it should, and this increased strain can shorten the lifespans of different components.
  2. Increased Humidity Levels
    • Part of the process of cooling air naturally involves removing humidity. If you notice a rise in humidity levels, especially in particular areas, contact your HVAC contractor. It could be a hidden leak somewhere, or it could be that there’s a problem with you HVAC unit. 
  3. Strange Noises
    • Commercial HVAC units are large, noisy machines that make a lot of noise. The majority of that noise should be the whirring of fans and belts. Your HVAC may need attention if you hear buzzing, rattling, banging, or clicking noises. 
    • Gurgling or hissing noises can indicate a leak in your system. Grinding noises usually occur within the motor fan with a broken component or foreign object.
  4. Unpleasant Odors
    • You may not spend a lot of time around your HVAC unit, but if you notice any strange odors such as chemicals or mold, it’s best to contact an HVAC expert.
    • After switching to heating for the season, a slight burning smell from your HVAC the first few times it starts is typical. If the smell continues or heavily smells like burning, call an HVAC repair technician. 
  5. Short Cycling
    • Have you ever turned on a vacuum or other high electric draw appliance and seen the lights flicker? There are two main reasons this may happen: your electric system is adjusting to the new energy draw, or when a motor is first turned on, the initial energy required to move things is much greater than the energy needed for regular operation. This initial activation is when components are under the most stress.
    • It is known as short cycling when an HVAC unit turns on and shuts off repeatedly every few minutes. If your system is short cycling, that means it’s under a considerable amount of stress. If you find your HVAC short cycling, turn it off until a repair technician can arrive and determine the problem. Don’t let your HVAC short cycle, or you’ll risk more expensive repairs.
  6. Increased Energy Bills
    • It’s always a good idea to pay attention to your electric bills. Sudden spikes in utility bills that don’t coincide with the weather indicate something is wrong with the HVAC system. When components break down in the HVAC, it consumes more energy to do the same job. Call an HVAC repair company if you see a considerable spike in your electric bill.
