Looking for expert HVAC services in Fairfield County, CT? Whether you’re battling freezing New England winters or humid summer heat, your HVAC system is your home’s first line of defense. At Edgerton, we’ve proudly served Connecticut homeowners and businesses since 1956, delivering top-tier heating, ventilation, and air conditioning (HVAC) solutions that prioritize comfort, efficiency, and reliability.
What Is an HVAC System?
HVAC stands for Heating, Ventilation, and Air Conditioning — a system that controls indoor temperature, humidity, and air quality. It consists of various components that work together to keep your home or business comfortable year-round. Key parts include:
- Furnace or heat pump (for heating)
- Air conditioner or heat pump (for cooling)
- Air ducts and ventilation system
- Thermostats and control systems
- Air filtration and purification units
Understanding how your system works can help you detect early signs of trouble and avoid costly repairs. For example, your furnace may rely on a gas valve and heat exchanger to generate warm air, while your central AC uses a compressor, condenser coil, and refrigerant to cool your home.
Common HVAC Problems in Fairfield County Homes
As heating & air conditioning systems age or experience seasonal strain, several issues can arise — especially in climates like Connecticut’s that demand year-round use.
1. Inconsistent Heating or Cooling
If one room feels like a sauna while another feels like a freezer, your ductwork may be unbalanced, or your system may be improperly sized.
2. Poor Airflow
Clogged filters, blower motor issues, or duct blockages can restrict airflow, lowering comfort and energy efficiency.
3. High Energy Bills
Older units or poorly maintained systems consume more energy to maintain performance, especially during peak seasons.
4. System Short Cycling
When your system turns on and off frequently, it could be caused by a malfunctioning thermostat, dirty coils, or low refrigerant levels.
5. Unusual Noises or Smells
Rattling, banging, or burning smells often indicate mechanical failure, electrical issues, or a dirty furnace burner.
