Top 5 Signs Your HVAC System Needs Maintenance

Updated: Jun 4

As a homeowner, keeping your HVAC system in top shape is essential. Regular maintenance ensures your home stays comfortable year-round and helps avoid costly repairs down the line. Here are the top five signs that your HVAC system needs some attention and what you can do about it.


Inconsistent Temperatures

Have you ever walked from your living room, which feels like a sauna, into your bedroom which feels like an igloo? This inconsistency in temperature is a common sign that your HVAC system needs maintenance. It’s often caused by issues such as a malfunctioning thermostat or problems within your ductwork.

I remember one winter, my own home had this exact problem. The upstairs was warm but the downstairs felt like a freezer. It turned out to be an issue with our ductwork not distributing heat properly. After a quick check and some adjustments, our home was back to a consistent temperature throughout.


What You Can Do:

  • Check the Thermostat: Ensure your thermostat is functioning properly and replace its batteries if necessary. A thermostat that is not working correctly can send inaccurate signals to your HVAC system, leading to temperature inconsistencies.

  • Inspect Ductwork: Look for visible signs of damage or disconnections in your ductwork. Use a thermometer to check for significant temperature variations between rooms. Properly sealed and insulated ducts help maintain consistent temperatures throughout your home.

  • Professional Inspection: Consider having a professional from Prime Heating and Cooling perform a thorough inspection to identify and fix ductwork issues. A professional can detect problems that might not be obvious to the untrained eye and ensure your system is balanced and efficient.

Unusual Noises

HVAC systems aren't silent, but if you start hearing unusual noises like banging, rattling, or squealing, it's time to pay attention. These noises often indicate loose parts, motor issues, or other mechanical problems that shouldn't be ignored.

I once had a customer who called me because their HVAC system was making a loud banging noise every time it turned on. It turned out that a small part had come loose inside the unit. A quick fix saved them from what could have been a much larger problem.


What You Can Do:

  • Identify the Noise: Listen carefully to identify the type and source of the noise. Common sounds include clicking (relay issues), hissing (refrigerant leak), and rattling (loose parts). Each noise can indicate a different issue that needs addressing.

  • Turn Off the System: To prevent further damage, turn off the system until a professional can diagnose the problem. Running a system with mechanical issues can lead to more severe damage and higher repair costs.

  • Record the Noise: Use your phone to record the noise. This can help technicians identify the issue more quickly and accurately. A recording provides valuable information that might not be as evident once the system is off.


High Energy Bills

Have you noticed your energy bills creeping up without a clear reason? An inefficient HVAC system could be the culprit. When your system is not operating efficiently, it works harder to heat or cool your home, leading to higher energy consumption.

A friend of mine experienced a sudden spike in their energy bills last summer. They initially thought it was due to the extreme heat, but a quick inspection revealed that their air filter was clogged, causing the system to overwork. After replacing the filter, their energy bills normalized.


What You Can Do:

  • Monitor Energy Usage: Use energy monitoring apps to keep track of your usage patterns. These apps can help you understand your energy consumption and identify unusual spikes.

  • Check and Replace Filters: Regularly check and replace your HVAC filters to ensure efficient airflow. Dirty filters can restrict airflow, making your system work harder and consume more energy.

  • Compare Bills: Compare your current energy bills with past bills to spot any unusual increases. A sudden rise in energy costs can indicate that your HVAC system is not running efficiently.

  • Professional Maintenance: Schedule regular maintenance checks to keep your system running efficiently. A professional can tune up your system, clean components, and ensure everything is working optimally.


Frequent Cycling

Frequent cycling, where your HVAC system turns on and off more often than usual, is another sign of trouble. This can be caused by a malfunctioning thermostat, dirty filters, or even an improperly sized system.

I recall a case where a customer's HVAC system was cycling every few minutes. It turned out that their thermostat was placed in direct sunlight, causing it to register inaccurate temperatures. After relocating the thermostat, the frequent cycling stopped, and the system functioned normally.


What You Can Do:

  • Check Thermostat Placement: Ensure your thermostat is placed in an optimal location away from direct sunlight, drafts, or other heat sources. A poorly placed thermostat can cause your system to cycle unnecessarily.

  • Replace Air Filters: Regularly replace your air filters to prevent blockages that can cause the system to overwork. Clean filters ensure proper airflow and reduce strain on the system.

  • System Sizing: Have a professional assess whether your system is the correct size for your home. An improperly sized system can lead to frequent cycling and inefficiency. A too large or too small system will not operate efficiently and can cause increased wear and tear.


Poor Air Quality

Your HVAC system plays a crucial role in maintaining indoor air quality. If you notice an increase in dust, humidity issues, or a musty smell, it might be due to poor HVAC performance. A well-maintained system filters out dust and allergens, keeping your air clean and healthy.

A family member of mine started experiencing allergy symptoms every time they were home. After checking their HVAC system, we found that the air filters were long overdue for a change, and the ducts needed cleaning. Once these were addressed, their symptoms improved significantly.

What You Can Do:

  • Replace Air Filters: Replace air filters regularly to ensure they effectively trap dust and allergens. Consider using HEPA filters for better air quality. Clean filters are essential for maintaining good indoor air quality.

  • Duct Cleaning: Schedule duct cleaning services to remove accumulated dust and debris. Clean ducts improve airflow and reduce the circulation of allergens in your home.

  • Add Air Purifiers: Consider adding air purifiers to your home to further improve air quality. Air purifiers can help remove pollutants and allergens from the air, providing a healthier environment.

  • Monitor Outdoor Air Quality: Keep an eye on outdoor air quality reports and take steps to mitigate its impact on your indoor environment. On days with poor outdoor air quality, keep windows closed and use air purifiers to maintain a clean indoor environment.

Additional Tips for Maintaining Your HVAC System

  • Seasonal Maintenance: Schedule professional maintenance checks at least twice a year, ideally in the spring and fall. Regular tune-ups can prevent issues before they become major problems and ensure your system is ready for the demands of summer and winter.

  • Keep Outdoor Units Clear: Make sure the area around your outdoor HVAC units is clear of debris, plants, and other obstructions. Proper airflow is essential for efficient operation.

  • Seal Leaks: Check for and seal any leaks in your ductwork to ensure that air is being efficiently distributed throughout your home. Leaks can lead to energy loss and uneven heating or cooling.

  • Use a Programmable Thermostat: Invest in a programmable thermostat to better control your home's temperature and reduce energy usage. These devices can help you set different temperatures for different times of the day, optimizing comfort and efficiency.
