As a premier HVAC company in Washington, DC, JC & JC Mechanical Contractors LLC frequently encounters a range of HVAC problems. These often include issues with the HVAC unit like a malfunctioning thermostat, poor air flow, dirty or clogged filters, and refrigerant leaks. We also deal with HVAC systems suffering from wear and tear, which can lead to inconsistent temperatures and increased energy consumption. Sometimes, the issue could be a more complex problem with the air conditioner or heating system such as faulty electrical connections or damaged ducts. We always recommend professional HVAC service to accurately diagnose and address these issues.

HVAC maintenance is crucial for ensuring the longevity and efficiency of your system. At JC & JC Mechanical Contractors LLC, our maintenance services include a comprehensive inspection of your HVAC system. We check the air conditioning unit, heating system, and all components of the HVAC unit. This includes cleaning or replacing filters, checking the refrigerant level, inspecting the condensate drain, and checking all electrical connections. We also clean and adjust blower components for optimal airflow. Regularly serviced HVAC systems often run more efficiently and have a longer lifespan.

As a rule of thumb, your HVAC system should receive professional service at least once a year. However, for optimal performance and to prevent potential HVAC problems, JC & JC Mechanical Contractors LLC recommends servicing your HVAC unit in the spring for the cooling system and in the fall for the heating system. Regular service ensures your HVAC system is running efficiently and can identify potential problems before they become major issues.

The frequency at which you should change your HVAC filter depends on the type of filter your system uses. As a general guideline, we recommend checking your filter every month. Basic filters should be changed every 1-3 months, while more advanced pleated filters can last 6-12 months before needing replacement. Keep in mind that if you have pets or someone in your home has allergies, you might need to change the filter more frequently. Regularly changing your HVAC filter is an essential part of maintaining a healthy and efficient system.

When you schedule a service call with a HVAC technician, it’s important to ask the right questions to ensure your HVAC system is in good hands. Some key questions to ask might include:

  1. What kind of maintenance should I be doing on my own between professional services?
  2. Are there any potential problems I should be aware of?
  3. How can I improve the energy efficiency of my HVAC system?
  4. What is the lifespan of my current system and when should I consider a new HVAC system?
  5. Is my system the right size for my home?


Remember, a good HVAC specialist will always be willing to answer your questions and provide the best possible quality service. At JC & JC Mechanical Contractors LLC, we pride ourselves on offering superior service and ensuring our customers have a clear understanding of their HVAC system‘s needs.
