Air filters trap mud, filth, and other particles, but over time, they’ll turn into clogged, reducing airflow. Blocked vents and soiled ducts may also impede air circulation, causing uneven heating or cooling throughout your home.
When to call a contractor: When you’ve replaced the air filter and cleaned the vents but still expertise poor airflow, it might indicate a more serious subject like a failing blower motor or ductwork problems. In such cases, it’s best to seek the advice of an HVAC professional to evaluate the system.
2. Refrigerant Leaks
Refrigerant is a crucial element in any air conditioning system, accountable for cooling the air before it’s circulated in your home. If the refrigerant level is low, your HVAC system will wrestle to cool efficiently, leading to higher energy bills and inadequate cooling.
When to call a contractor: Refrigerant leaks aren’t something residenceowners can typically handle. These leaks not only reduce the system’s effectivity but may pose environmental hazards. Call a licensed contractor to find and repair the leak, as well as recharge the refrigerant levels. It’s vital that this task is handled by a professional, as improper handling of refrigerants can be dangerous.
3. Thermostat Points
Typically, the problem with your HVAC system lies not within the equipment itself but with the thermostat. If your house will not be reaching the desired temperature or the system is cycling on and off too steadily, it could be resulting from a malfunctioning thermostat.
When to call a contractor: First, check if the thermostat is set to the proper mode and temperature. If it’s still not functioning correctly after resetting it, it may be time to replace the thermostat.

If your system starts making loud or unusual sounds, turn it off and call an HVAC professional to diagnose and resolve the issue before it causes more damage.
5. Brief Cycling
Brief cycling occurs when your HVAC system turns on and off in short intervals, stopping it from completing a full heating or cooling cycle. This subject can lead to higher energy consumption and uneven indoor temperatures. Quick biking is often caused by an oversized system, a malfunctioning thermostat, or a dirty air filter.
When to call a contractor: If changing the air filter doesn’t remedy the problem, brief cycling may point out a more significant concern like a refrigerant leak or electrical malfunction. A contractor can consider your system and determine the basis cause of the problem.
6. Unpleasant Odors
In the event you discover musty or burning smells coming from your HVAC system, it might be a sign of mold growth within the ductwork, a burned-out motor, or a clogged condensate drain.

If totally different rooms in your house are experiencing varying temperatures, it could indicate a problem with your HVAC system. Uneven heating or cooling is often caused by poorly insulated ductwork, improper system sizing, or issues with the blower motor.
When to call a contractor: If adjusting the vents or checking the thermostat does not fix the problem, a contractor ought to be called. They will determine whether or not the problem is due to ductwork, zoning problems, or an undersized or oversized system.
8. Elevated Energy Bills
A sudden spike in your energy bills may very well be a sign that your HVAC system isn’t working efficiently. Issues like dirty air filters, refrigerant leaks, or malfunctioning components can cause your system to work harder, consuming more energy.
When to call a contractor: In case your energy bills have increased without a significant change in usage patterns, it’s a good suggestion to have your HVAC system inspected. A professional contractor can establish the underlying challenge and recommend repairs or maintenance to improve the system’s efficiency.
Conclusion
