HVAC Resource Guide
Western Mass winters push heating systems hard, and our humid summers put AC units to the test. Here are the most common HVAC problems we see across Hampden, Hampshire, and Franklin counties, and what you can do about them.
This is one of the most common calls we receive, especially during Massachusetts winters. Causes can range from a tripped breaker or blown fuse to a faulty thermostat, a dead pilot light, or a malfunctioning ignition system. Before calling a technician, check your thermostat settings, circuit breaker, and furnace power switch.
If some rooms are too hot while others are too cold, you may have ductwork issues, improperly sized equipment, or blocked vents. This is especially common in older Western Mass homes with additions or converted attics. A professional can perform a load calculation and duct inspection to identify the source of the imbalance.
Banging, squealing, rattling, or humming sounds from your HVAC system often indicate loose components, worn belts, motor bearing issues, or debris in the system. Don't ignore unusual noises. They often signal a problem that will worsen over time.
If your heating or cooling bills have spiked, your system may be running inefficiently. Common causes include dirty filters, leaking ductwork, low refrigerant, or an aging system that's past its prime. A tune-up can often improve efficiency by 10-25%.
When your HVAC system turns on and off frequently without completing a full cycle, it could be caused by an oversized system, a dirty filter restricting airflow, thermostat issues, or a failing compressor. This wastes energy and puts unnecessary wear on your equipment.
Dusty, musty, or stale air in your home can be caused by dirty filters, mold in ductwork, or inadequate ventilation. Regular maintenance and air quality assessments can dramatically improve your indoor environment, which matters when your home is sealed up tight through a Western Mass winter.
