The Most Common Reasons Behind HVAC Service Calls

Having issues with your HVAC system can be due to several factors, with some easily resolved just by cleaning coils or replacing filters. But if you choose to ignore some of more complex issues, they’ll only grow into bigger problems that force you to pay for the needed repairs. 

To avoid paying more than you should, it’s recommended that you stick with a regular maintenance schedule. If you don’t, you might have to schedule a service call for any of the below reasons.

Dirty Filters

Replacing your filter regularly is one of the most important things you can do to extend your system’s lifespan and efficiency. If your filter is dirty, airflow becomes restricted, which causes your unit to work much harder to circulate air through your home. This puts unnecessary strain on the blower, which will result in comfort issues as well. Having a dirty filter can also cause the furnace to overheat and shut off on high limit, so it’s best to replace them when needed.

Weird Noises

The noises coming from your HVAC are usually part of normal operation, but sometimes it may indicate that you have a mechanical problem. For instance, a whining or squealing motor can mean the bearings in an inducer motor or blower motor are failing. The replacement of the motor may be needed to avoid a failure. Whether the noises are caused by airflow issues or dirty burners, you shouldn’t ignore these signs and have them checked by a trusted technician as soon as possible.

Water Leaks

Your HVAC system produces condensation that drains through the drain pipes. If there isn’t proper drainage, then you’ll have water leaks. In fact, clogged pipes are one of the most common problems for HVAC units, especially when the condensation overflows out of the drain line and the drain pan. To prevent this, just pour bleach down the pipes every now and then. But if cracked pipes are the cause of your leaking, then you might have to get it repaired professionally. Other parts of the HVAC system can leak as well, such as the heat exchanger, evaporator drain and collector box.

Blower Running Continuously

As professional air conditioner repair contractors, we know that a few reasons a unit’s blower may run continuously. First, check the fan switch on the thermostat. The motor will run continuously when the thermostat is set to the fan on position. It often happens that homeowners switch the fan switch to on by accident. There’s a fan relay in the furnace that turns the blower on when there is a call for heat, but if the relay sticks, the blower will not shut off. If this doesn’t stop your blower, you may want to call in your trusted technician.

Leaking Refrigerant

Another common issue that warrants HVAC service calls is leaking refrigerant. This can be a major inconvenience as it’s responsible for cooling and dehumidifying the airflow. Some signs of a refrigerant leak are inefficient cooling and fluctuating temperatures. Having a leaking refrigerant component also means the air produced won’t be cold enough, which leaves the room warm and uncomfortable. This also makes the condenser and other parts of your system go into overtime to compensate.

If the leak is left unaddressed, you’ll get into more serious problems that can be costly to repair. As a result of the leak, your refrigerant levels will run low. If you think you’re having this problem with your system, it’s best to call an HVAC professional who will charge the system with the appropriate amount as a part of the repair.

Noticeable Decrease in Efficiency

You might notice that the room may not be cooling down or warming up as effectively as before, so you’re going to have to go through a long list of potential issues. If you’ve already changed your air filters, then the problem may lie somewhere else in your HVAC system, such as blockage in the registers or around the outside of your unit. Clear these areas to allow your unit to work as expected. Dirty components can also reduce the efficiency of your HVAC system, but in this case, you may need to call a technician to clean the whole system with a special cleaner.

Dirty Condenser or Evaporator Coils

If regular maintenance hasn’t been done, then your unit may likely not work as well as it should. Accumulated dirt and debris can clog the coils of your system, which significantly reduce the efficiency and cause it wear out sooner than anticipated. To avoid this, you can hose off the outdoor coil after shutting off the power to the condenser.

The indoor evaporator coil can also become dirty, especially if the air filters aren’t changed regularly. A dirty evaporator coil reduces the efficiency of both your furnace and air conditioner, which make your system work harder and consume more energy. If you haven’t cleaned your coils at all, you’ll need a trained service technician to clean them thoroughly.

Mechanical Wear and Tear

Your HVAC system relies on several mechanical components, and its performance can be negatively impacted by their normal wear and tear. These include the belts and bearings, which may result in airflow issues, overheating and poor heating and cooling. As such, regular maintenance is recommended to check for worn or stretched belts and oiling bearings, and have them serviced when needed.

Lack of Maintenance

Chances are, you’ve spent a lot for your home heating and cooling system, so you shouldn’t think twice about protecting your investment. Neglecting regular maintenance will mean unexpected breakdowns, increased energy cost, poor performance and other unwanted issues.

This is why a regularly scheduled maintenance by a trusted licensed service technician is needed to keep your HVAC system in good working condition. It’s also worth every cent to have it maintained professionally as many of the most common and more expensive problems can easily be avoided with professional maintenance and care.
