Common HVAC problems typically revolve around issues with the air conditioning unit or the heating system. One prevalent problem is insufficient cooling or heating, which may stem from a lack of maintenance or a faulty thermostat. Blocked or leaky ducts can also significantly affect the efficiency of your HVAC system.

In addition, you may face problems with the HVAC unit itself, such as mechanical wear and tear, electrical issues, or even refrigerant leaks in an air conditioner or heat pump. Lastly, a noisy HVAC system often signals a malfunctioning component that needs attention from a skilled HVAC technician like those at JC & JC Mechanical Contractors LLC.

HVAC maintenance from JC & JC Mechanical Contractors LLC is a comprehensive process that involves several steps. Initially, we inspect the entire HVAC system, including the air conditioning and heating units, to identify any visible issues.

Our maintenance service also includes cleaning evaporator and condenser coils, checking the refrigerant level, inspecting and cleaning the blower components, and examining the heat exchanger and heating elements. We also verify the system’s operation, thermostat settings, and electrical connections.

To ensure your HVAC system runs efficiently, we lubricate all moving parts and check the system controls. Lastly, we examine the air filter and replace it if necessary, ensuring optimal air quality.

Typically, JC & JC Mechanical Contractors LLC recommends having your HVAC system serviced at least twice a year, preferably in the spring and fall. These regular service checks allow our HVAC technicians to catch any potential problems early and ensure your system runs smoothly during the hottest and coldest months.

However, if you notice any issues with your system, such as strange noises, decreased efficiency, or uneven cooling or heating, it’s advisable to schedule a service call immediately. Regular maintenance can prevent costly repairs and extend the life of your HVAC unit.

The frequency of changing your HVAC filter depends on several factors, including the type of filter, the size of your home, and whether you have pets or anyone in the house with allergies. On average, it’s recommended to change the filter every 90 days. However, if your home has pets or someone with allergies, it’s advisable to replace the filter every 30-60 days.

Regularly changing your filter helps to keep your HVAC system running efficiently, improving your home’s air quality, and reducing your energy bills. As part of our HVAC maintenance service, JC & JC Mechanical Contractors LLC’s technicians will check your filter and replace it if necessary.

When your HVAC technician arrives for a service call, asking the right questions can help you understand your system’s condition and the necessary steps to maintain it. Here are some questions you may want to ask:

  1. Can you explain what’s wrong with my HVAC system?
  2. What maintenance can I perform myself between visits?
  3. How often should my specific system be serviced?
  4. When will I likely need to replace my current HVAC unit?
  5. Can you provide any tips to improve my system’s efficiency?


At JC & JC Mechanical Contractors LLC, we believe in transparency and education. Our HVAC technicians are always ready to answer your questions and provide useful tips to keep your system running smoothly.
