What to expect from our heating repair service.
Tennessee winters don't last long, but when a cold snap hits Chattanooga the heat needs to work, period. Cranfield Services repairs every kind of residential heating system: 80% and 90%+ gas furnaces, electric furnaces, air-source heat pumps, and dual-fuel hybrids. Common calls we resolve every week include weak airflow, short cycling, a system that runs but won't heat, error codes on the control board, ignitors that won't light, flame sensors that need cleaning, and blower motors at end of life. Every gas heat repair includes a free combustion safety check, we want you and your family safe, not just warm. We carry the most common parts on every truck so most no-heat calls are fixed in one visit. And because we live here too, we know which neighborhoods get hit hardest when temperatures drop, we prioritize emergency heat calls accordingly.
Frequently asked questions.
Why is my furnace blowing cold air?+
Common causes include a tripped high-limit switch, a failed ignitor or flame sensor, a clogged filter restricting airflow, or a thermostat set to 'fan on' instead of 'auto.' A technician can pinpoint it in a single visit.
How often should I service my heating system?+
Once a year, ideally in early fall. Annual maintenance catches small issues before they become winter emergencies and keeps your manufacturer warranty valid.
Do you work on heat pumps in cold weather?+
Yes. We diagnose defrost issues, reversing valves, low-charge problems, and auxiliary/emergency heat strips on every major heat pump brand.
