10 Common HVAC Problems, and Kelvin’s Recommended Solutions
From keeping your infrastructure cool during summers to ensuring warmth in the winter, your HVAC unit works tirelessly throughout the year. But like any machine, it isn’t immune to wear and tear. Over time, even the most reliable system can encounter issues that impact efficiency, comfort, and even your energy bills. The good news? Many of these issues are preventable or fixable if you know what to look for and take timely action.
That’s why Kelvin Air Conditioning and Ventilation Systems – a leading team of HVAC contractors in Mumbai and annual HVAC maintenance contractors – decided to share the 10 most common HVAC problems and share practical solutions to tackle them. Read on!
Dirty or Clogged Filters
The Problem: Dust and debris get trapped in the filters, obstructing the airflow and making the system work harder.
The Fix: Replace disposable filters every 1 to 3 months, or clean the reusable ones regularly. This simple task improves air quality and reduces excess energy consumption.
Refrigerant Leaks
The Problem: If the air coming through your vents is warm rather than cool, low refrigerant levels might be the reason. Leaks can also cause damage to the compressor.
The Fix: Always hire a licensed HVAC maintenance technician to check for leaks, repair the leaks, and recharge the refrigerant. Here, a do-it-yourself approach is usually not helpful.
Thermostat Issues
The Problem: A faulty thermostat could lead to inconsistent temperatures, frequent cycling, or complete shutdown of the system.
The Fix: Replace the thermostat batteries. If that doesn’t work, recalibrate or replace the thermostat with a smart model for better control and efficiency.

Drainage Problems
The problem: Clogged drains in the condensate can cause water leaks, mold formation, and dampness indoors.
The fix: Periodically flush the drain with vinegar or a cleaning solution. If clogging keeps occurring, call a professional.
Uneven Heating or Cooling
The problem: Some rooms are too hot while others remain cool. Duct leaks, poor insulation, or blocked vents usually cause it.
The fix: Check the vents for blockages and make sure the ducts are sealed correctly. Sometimes, a zoning system can be put in place to balance the temperature in specific areas.
Dirty Coils
The problem: Dust accumulating on the condenser or evaporator coils obstructs heat exchange and stresses the system
The fix: Schedule annual HVAC maintenance for cleaning the coils professionally. Do not use chemicals that may cause harm to the parts.
Frequent Cycling
The problem: Short cycling (system turning on and off too frequently) wastes energy and stresses components.
The fix: Causes may include clogged filters, oversized units, or thermostat problems. Experienced HVAC professionals like Kelvin Air Conditioning and Ventilation Systems can diagnose and correct the root cause.
Blown Fuses or Tripped Breakers
The problem: Electrical issues are common when the system overworks, especially during peak usage.
The fix: Reset the breaker first. If it trips repeatedly, it may indicate motor issues or electrical faults—contact a technician immediately.
Strange Noises
The problem: Rattling, buzzing, or squealing noises can point to loose parts, motor issues, or worn-out belts.
The fix: Turn off the system and schedule a professional inspection. Ignoring unusual sounds may lead to costly repairs.
Lack of Maintenance
The problem: Most HVAC breakdowns result from skipped maintenance. Without tune-ups, small issues turn into expensive repairs.
The fix: Schedule preventive maintenance at least once a year. A professional checkup includes cleaning, inspection, and performance testing to keep the system running efficiently.
