Which brands do you service?

Our technicians service equipment from many leading HVAC manufacturers, including Carrier, Trane, Mitsubishi, and Bosch. Call with your model information to confirm support.

How fast can you get to me in an emergency?

Maintenance-plan members can request 24/7 emergency service and receive priority scheduling, subject to call volume, weather, location, and technician availability. Non-plan customers can request service during normal business hours.

Should I replace or repair?

We'll give you both options honestly. As a rule of thumb, if your system is over 12-15 years old and the repair is more than half the replacement cost, replacement usually wins.

Do heat pumps work in Connecticut winters?

Modern cold-climate heat pumps work efficiently down well below 0°F and are a great option for many CT homes — often paired with backup heat for the coldest stretches.

HEATING & COOLING
