Signs Your System is Due for Maintenance

Your HVAC system often gives clues that it needs service. Ignoring these warnings can lead to bigger problems. Here are common signs that it’s time for an HVAC system tune-up:

Unusual Noises: Groans, squeals, or rattles can indicate loose parts or motor issues that a tune-up can address.
Weak Airflow: If air from your vents feels less powerful, it could be caused by dirty filters, blocked ducts, or blower motor issues.
Inconsistent Temperatures: If you’re constantly adjusting the thermostat, your system may be struggling with calibration or component inefficiencies.
Increased Humidity: If your indoor air feels clammy even when the AC is running, your system may not be removing moisture effectively.
Higher Energy Consumption: A sudden spike in utility bills is a telltale sign of inefficiency. A system can lose 5%-15% efficiency each year without maintenance.
Frequent Cycling: A system that turns on and off too frequently (short cycling) is inefficient and experiences increased wear.

A timely HVAC system tune-up can resolve these issues, restoring comfort and preventing more serious problems.

How Often Should You Schedule a Tune-Up?

For HVAC system tune-ups, consistency is key. We recommend scheduling a tune-up at least once a year, but for optimal performance, semi-annual maintenance is best.

Spring AC Tune-Up: Schedule your air conditioning tune-up in the spring to ensure your AC is ready for summer heat and to prevent breakdowns.
Fall Furnace Tune-Up: The best time for a heating system tune-up is in the fall, before cold weather arrives, to ensure reliable and safe operation.

This twice-a-year approach is ideal because your cooling and heating systems have different needs. A spring tune-up focuses on cooling components, while a fall tune-up emphasizes heating. This ensures both aspects of your HVAC system are properly maintained. Older systems or those with high usage may benefit from more frequent checks. Regular tune-ups also help maintain compliance with manufacturer warranties, which often require annual professional service.

How long does an HVAC tune-up appointment take?

A professional HVAC system tune-up is efficient, typically taking 1 to 2 hours to complete. The exact duration can depend on the complexity of your system. If our technicians find minor issues that can be fixed on the spot, it may add a few minutes but can prevent a future breakdown. For any significant repairs, we will discuss our findings with you and schedule a separate visit. Our goal is to be thorough without disrupting your day.

What is the role of refrigerant in my AC system?

Refrigerant is the essential heat transfer fluid in your air conditioning system. It makes cooling possible by absorbing heat from inside your home and releasing it outside.

This process, known as the refrigeration cycle, involves the refrigerant changing between a liquid and a gas. Inside, liquid refrigerant in the evaporator coil absorbs heat from your indoor air, turning into a gas. This gas travels to the outdoor condenser unit, where it releases the heat and turns back into a liquid. This cycle is continuous and occurs in a closed loop, meaning refrigerant should never be “used up.”

Signs of low refrigerant, such as poor cooling or hissing sounds, almost always indicate a leak. Professional handling is required for all refrigerant-related issues due to safety, environmental regulations, and the need for specialized equipment. If you suspect a refrigerant problem, call a certified professional.
