Introduction
For homeowners in Edwardsville, IL, having a reliable heating, ventilation, and air conditioning (HVAC) system is essential for comfort throughout the year.

Understanding Your HVAC System
The first step in troubleshooting any HVAC issue is to understand how the system works. An HVAC system typically consists of:
- Heating Unit: Usually a furnace or heat pump.
- Cooling Unit: Typically an air conditioning unit or central air system.
- Ventilation: Ducts that circulate air throughout your home.
- Thermostat: The control center for your heating and cooling needs.
By familiarizing yourself with these components, you’ll be better equipped to identify issues as they arise.

What Causes Temperature Fluctuations?
One of the most common complaints from homeowners is uneven temperatures throughout their homes. This problem can stem from several factors:
- Blocked or dirty vents
- Poor insulation
- Malfunctioning thermostat
- Uneven ductwork distribution
How to Fix It?
Check Vents: Ensure that all vents are open and free from obstructions. Inspect Insulation: Examine areas like attics and basements for proper insulation. Thermostat Calibration: Consider recalibrating your thermostat or replacing it if it's old or malfunctioning. 2. Strange Noises from Your System
Identifying Noises
Every HVAC unit will make some noise, but loud or unusual sounds can indicate problems:
- Banging noises could suggest loose parts
- Hissing might point to a refrigerant leak
