Heating failures during Connecticut winters create urgent situations requiring immediate professional response. Greenwich experiences freezing temperatures that make functional heating essential for comfort, safety, and property protection. Our heating technicians service all system types including gas furnaces, oil furnaces, electric furnaces, heat pumps, and hydronic boilers. We diagnose ignition failures, thermostat problems, blower issues, and heat exchanger concerns with safety as our priority. Every heating repair includes carbon monoxide testing to ensure safe operation after repairs are completed.
Heating system diagnosis prioritizes safety. We begin with combustion analysis for fuel-burning systems, testing carbon monoxide levels. Ignition systems are tested for gas and oil furnaces. Heat exchanger inspection identifies cracks that could leak combustion gases. Blower operation is verified. Thermostat function and calibration are checked. For heat pumps, refrigerant levels and defrost operation are evaluated. Electrical components are tested throughout. This systematic approach ensures accurate diagnosis and safe operation.
Greenwich's coastal location brings moderate winter temperatures compared to inland Connecticut, but heating remains essential. Salt air can affect outdoor heat pump components. Storm-related power outages may interrupt heating, making backup options important. We recommend annual system inspection for coastal properties.

Answers
Frequently asked questions
Why isn't my furnace producing heat?
No heat from furnaces typically results from ignition failures, thermostat problems, or blower issues. Gas furnaces may have pilot light or electronic ignition failures. Thermostat batteries or settings may be incorrect. Blower motors can fail, preventing heat distribution. We systematically check each component.
How often should heating systems be inspected?
Annual professional inspection before heating season is strongly recommended. This ensures safe operation, identifies developing problems, and maintains efficiency. For older systems, bi-annual inspections provide additional safety assurance.
Why does my furnace keep turning on and off frequently?
Short cycling indicates overheating, dirty filters, thermostat problems, or oversized equipment. Clogged filters restrict airflow, causing overheating and safety shutoff. Thermostat location or calibration issues can cause rapid cycling. We identify the specific cause.
Is a cracked heat exchanger dangerous?
Yes, cracked heat exchangers can leak combustion gases including carbon monoxide into living spaces. This is a serious safety concern requiring immediate attention. We test for heat exchanger integrity and recommend replacement when cracks are found.

“The boiler short cycled on the coldest night of January and the top floor never got past 62. He purged air out of two zones, changed a zone valve that was stuck part open, and checked the circulator. All three floors heat evenly now, and he flagged an aging expansion tank to keep an eye on.”
“Compressor never shut off and the interior sat around 45 degrees. The condenser was packed with dust and dog hair, and the fan motor had quit. He cleaned the coil, fitted a new motor, and it cycles normally.”
“Lower zone climbed six degrees overnight. New zone sensor, door gasket reseated, and it holds steady now. My one complaint is that the sensor took eight days to come in.”
“The oven stalled below 300 no matter what I set it to. He measured igniter draw, found it weak, and changed the igniter and the safety valve as a pair. Roasting temperatures have read true ever since.”
