How Often Should I Service My HVAC System?

Regular maintenance is essential to keeping your heating and cooling system in top shape. We recommend scheduling a professional tune-up at least twice a year—once before the summer season and once before winter. Routine service helps prevent costly breakdowns, extends the lifespan of your unit, and improves energy efficiency.

What Are the Signs That I Need HVAC Repair?

If your HVAC system is acting up, here are some common signs that indicate you may need repair:

  • Weak Airflow – If the air coming from your vents is weak, your system may have a clogged filter, duct issues, or a failing blower.
  • Inconsistent Temperatures – If some rooms are too hot while others are too cold, your HVAC system might have a thermostat issue, duct leaks, or an aging system.
  • Unusual Noises – Banging, rattling, screeching, or grinding sounds could indicate mechanical problems such as loose parts or a failing motor.
  • Strange Odors – A musty smell may indicate mold in the ducts, while a burning smell could mean electrical issues.
  • Short Cycling – If your system frequently turns on and off without completing a full cycle, it may be overheating, have thermostat problems, or need maintenance.
  • Higher Energy Bills – A sudden increase in energy costs could mean your HVAC system is working harder than it should due to inefficiency or malfunction.
  • Excess Humidity – If your home feels excessively humid, your system may not be regulating moisture properly.
  • Leaking or Moisture Buildup – If you see water pooling around your unit, it could be due to a clogged drain line or refrigerant leak.
  • No Heating or Cooling – If your system isn’t producing heat in the winter or cool air in the summer, it may have a refrigerant leak, compressor issue, or thermostat failure.
  • Constantly Running System – If your HVAC system runs continuously without shutting off, it could indicate an issue with the thermostat, sensors, or internal components.

If you notice any of these signs, it’s best to schedule an inspection with our professional HVAC technicians before the problem worsens.
