The Most Common Fall HVAC Problems

HVAC Problems

As the leaves start to change and cool breezes replace the summer heat, it’s a sign that fall is upon us. But with that transition comes an array of potential problems for your HVAC system. Many homeowners find that, as they switch from air conditioning to heating, unexpected issues can emerge. 

In this blog post, we’ll delve into the most common HVAC problems you might encounter during the fall season, providing insight on how to identify these issues early and tips to prevent them from burgeoning into more significant problems. So, let’s prepare your HVAC system for the cooler months ahead together!

Identifying Cold Air Leaks Around Your Home

  • Poor Heat Circulation: It is common for heat to not circulate evenly around the house due to blocked or leaking ducts. If you notice some rooms are warmer than others, it might be time to seek professional help.
  • Furnace Noise: Unusual sounds emanating from your furnace could indicate mechanical problems. A professional HVAC technician can diagnose these noises and perform necessary repairs.
  • Frequent Cycling: If your HVAC system is frequently turning on and off, it could be due to an oversized system, poor insulation, or thermostat issues.
  • Ignition or Pilot Control Problems: A faulty ignition or pilot could make it difficult to heat a home or commercial space. This can be caused by thermocouple problems, clogs, or drafts.
  • Dirty Filters: Over time, HVAC filters can accumulate dirt and dust which may result in reduced efficiency and potentially damage the system. Regular filter changes are essential for optimal performance.

Checking Your HVAC Filter for Clogs and Replacing it if Necessary

Ensuring that your HVAC filter is clean and free of clogs is crucial to the overall performance and longevity of your heating system. A clogged filter can lead to decreased efficiency, higher energy costs, and even system failure. Here’s a step-by-step guide on how to check your HVAC filter for clogs and how to replace it if necessary:

  • Locate Your Filter: You can typically find your HVAC filter behind the return air vent or inside the HVAC system itself. Refer to your system’s manual if you’re unsure where it is.
  • Inspect the Filter: Once you’ve located your filter, remove it and hold it up to a light source. If you can’t see light passing through, that’s a sign your filter may be clogged.
  • Replace If Necessary: If your filter is clogged, it’s time to replace it. Make sure to purchase the correct size and type for your HVAC system. Follow your system’s manual for instructions on how to install the new filter.
  • Regular Checks: It’s a good habit to check your filter at least once a month, especially during high-usage months. Regular checks will ensure your HVAC system runs efficiently, saving you from potential costly repairs and energy bills.

Remember, your HVAC system is critical to your home’s comfort during the cooler months.

Scheduling Regular Maintenance to Ensure Your System is Running Properly

  • Engage a Professional: To keep your HVAC system functioning optimally, it’s advisable to schedule regular maintenance checks with a professional. Experts can spot potential problems early and perform preventative maintenance.
  • Check the Thermostat: Ensure your thermostat is working correctly. If it’s faulty, your HVAC system might not heat your home efficiently.
  • Inspect Outdoor Units: Leaves and other debris can accumulate in your outdoor units, causing them to work harder and increasing energy usage. Regularly inspect and clean these units.
  • Maintain a Clear Space: Try to keep the area around your HVAC units clear of furniture and clutter. A clear space allows for better airflow and efficiency.
  • Inspect Vents and Ducts: Regularly check your vents and ducts for dust accumulation and blockages. Clean them regularly to ensure efficient heat distribution throughout your home.

Inspecting the Outdoor Unit for Debris or Damage

The outdoor unit of your HVAC system is exposed to the elements and can often accumulate debris or get damaged. Regular inspection is important to keep your system running efficiently. Here are some steps to help you inspect your outdoor unit:

  • Examine the Exterior: Start by visually inspecting the unit for any obvious signs of damage. This could include dents, rust, or loose parts. If you notice anything unusual, it may be time to call a professional.
  • Check for Debris: Over time, leaves, dirt, and other debris can gather around and inside your outdoor unit, potentially causing it to overheat. Ensure you clear away any debris found around the unit.
  • Inspect the Fan: Check the fan for any signs of damage. Bent or broken blades can affect the efficiency of your system.
  • Check the Coil: The coil should be clean and free of dirt or grime. A dirty coil can restrict airflow and reduce system efficiency.
  • Professional Inspection: While you can perform basic checks yourself, it’s advisable to have a professional HVAC technician conduct more thorough inspections. They have the expertise to identify and resolve any hidden issues that might not be immediately apparent.

Remember, regular inspection and maintenance of your outdoor unit can go a long way in preventing unexpected HVAC problems, especially during the change of seasons.

Testing the Thermostat to Make Sure It’s Working Properly

Your thermostat plays a pivotal role in controlling your HVAC system and ensuring your home stays at a comfortable temperature. Testing it can help detect any issues early and maintain system efficiency. Here’s how to test your thermostat:

  • Step 1: Adjust the Temperature: Start by turning the thermostat up a few degrees higher than the current room temperature, and listen for the furnace to start running.
  • Step 2: Wait: Give it a few minutes. If your furnace doesn’t start running, this may be a sign that your thermostat isn’t functioning properly.
  • Step 3: Check the Wiring: Turn off the power and remove the thermostat cover to inspect the wiring. Look for any loose or disconnected wires. But remember, if you are unsure about handling electrical components, it’s best to contact a professional.
  • Step 4: Clean the Interior: Dust accumulation within the thermostat can affect its performance. Gently clean the interior using a soft brush or compressed air.
  • Step 5: Replace the Batteries: If your thermostat is battery-powered, try replacing the batteries as these can often be the cause of thermostat problems.

If you’ve conducted these tests and your thermostat is still not functioning correctly, consider calling a professional HVAC technician to diagnose and resolve the issue. A faulty thermostat can lead to inefficiencies in your HVAC system, resulting in higher energy costs.
