Gervais Heating & Air Conditioning | Experienced HVAC Services in Andover, MA

Short cycling in Andover is often caused by an oversized unit, a dirty air filter restricting airflow, or a faulty flame sensor or thermostat. It can also be a sign your system is working too hard due to aging components. Our technicians perform a thorough diagnostic to pinpoint the exact cause—often a simple fix—to restore proper operation, improve comfort, and prevent higher energy bills.

Consider replacement if your system is over 15 years old, requires frequent repairs, or your energy bills are climbing steadily. Other signs include uneven heating, excessive noise, or the system struggling to maintain temperature. We provide honest, no-pressure assessments in your Andover home, comparing repair costs against the long-term savings and reliability of a new, high-efficiency system tailored to your needs.

For older Andover homes, biannual professional tune-ups are crucial. We focus on cleaning components like the flame sensor and heat exchanger, checking for carbon monoxide safety, ensuring proper airflow, and calibrating the thermostat. This proactive maintenance helps aging systems run more efficiently, reduces the risk of sudden breakdowns during cold snaps, and can extend the life of your equipment.
