Why Is My HVAC System Not Working?

When your HVAC system stops working, it can be incredibly frustrating. Several issues can cause heating or cooling failures, and understanding these common problems can help you identify whether a quick fix is possible or if you need professional assistance.

A clogged air filter is one of the most frequent culprits. If your filter is dirty, it blocks airflow, making your system work harder and sometimes causing it to shut down. Checking and replacing your filter every one to three months can prevent many issues. Thermostat settings should also be checked. If the thermostat is set incorrectly or the batteries are dead, your system may not function properly.

A tripped circuit breaker can cut power to your HVAC system, making it seem like it's not working. Resetting the breaker may solve the issue. Ice buildup on the coils due to restricted airflow or refrigerant leaks can cause your air conditioner to stop cooling. If you notice ice, turning off the system and allowing it to defrost is the first step. A faulty pilot light or ignition system can prevent gas furnaces from producing heat, often requiring professional repair.

If these common problems don’t resolve the issue, call American Star at 847-241-2834 to get fast, professional service.

How Can I Troubleshoot My HVAC System Before Calling a Pro?

Before scheduling a service appointment, try these simple troubleshooting steps:

Check your thermostat settings. Make sure it is set to "heat" in the winter and "cool" in the summer. If it is battery-operated, replace the batteries to ensure proper function. Inspect your air filter and replace it if it looks dirty. A clogged filter can cause airflow problems, making your system inefficient.

Reset your circuit breaker if your HVAC system won’t turn on. Locate the breaker box, find the HVAC system switch, and reset it. Sometimes, power surges can trip the breaker, causing your unit to stop working. Look for ice buildup on your air conditioning unit. If ice is present, turn off your system and let it defrost completely before restarting.

Check air vents throughout your home. Blocked vents reduce airflow and can make certain rooms feel colder or hotter than others. Make sure all vents are open and unblocked by furniture or other objects. If your system still isn’t working, call American Star at 847-241-2834 for expert assistance.

How Often Should I Service My HVAC System?

Regular HVAC maintenance is essential for keeping your system running efficiently and preventing costly repairs. Experts recommend changing your air filter every one to three months, scheduling professional tune-ups twice a year—once before summer and once before winter—and cleaning your air ducts every three to five years.

Regular maintenance improves energy efficiency, extends the lifespan of your system, and ensures your home’s air quality remains healthy. Skipping maintenance can lead to system breakdowns, poor performance, and higher energy bills.

When Should I Replace My HVAC System?

An HVAC system that is well-maintained can last 10 to 15 years, but several signs indicate it may be time for a replacement. If your system requires frequent repairs, it may be more cost-effective to replace it rather than continue paying for expensive fixes. Rising energy bills often indicate that your HVAC unit is losing efficiency and working harder to maintain comfortable temperatures.

Uneven heating or cooling, where certain rooms in your home are noticeably warmer or colder than others, can signal that your system is struggling to distribute air properly. Loud noises, such as rattling, banging, or squealing, indicate mechanical issues that could require significant repairs or a full system replacement.

If you’re unsure whether to repair or replace your HVAC system, call 847-241-2834 for a consultation.

What Size HVAC System Do I Need for My Home?

Choosing the right size HVAC system is critical for efficiency and comfort. A system that is too small will struggle to heat or cool your home properly, leading to overworking and breakdowns. A system that is too large will cycle on and off frequently, reducing efficiency and causing unnecessary wear and tear.

Factors that determine the correct system size include square footage, ceiling height, insulation levels, and climate. An expert HVAC technician can perform a BTU (British Thermal Unit) calculation to determine the best system size for your home.

How Can I Lower My HVAC Energy Costs?

Saving money on heating and cooling costs is important for many homeowners. Upgrading to a smart thermostat allows you to program temperature settings that optimize efficiency. Sealing drafts and improving insulation prevent heat loss in winter and help keep cool air inside during summer.

Closing blinds and curtains blocks sunlight, reducing the amount of heat that enters your home. Using ceiling fans to circulate air reduces the strain on your HVAC system, improving efficiency and lowering energy costs.

Is HVAC Maintenance Really Necessary?

Yes! Regular HVAC maintenance is essential for preventing costly repairs, extending the lifespan of your system, and ensuring safe operation. Ignoring maintenance can lead to system breakdowns, poor air quality, and increased energy bills.

Routine service can also help identify small issues before they turn into expensive problems, saving you money in the long run. Preventative maintenance ensures that your HVAC system runs at peak performance, keeping your home comfortable in all seasons.
