Common questions
Helpful answers before you schedule.
Do you repair both gas and electric heating systems?
Yes. Liquid HVAC diagnoses gas furnaces, electric heat kits, air-handler heating components, thermostats, controls, blowers, and related airflow problems.
Is a heat pump the same as a furnace?
No. A heat pump moves heat using the refrigeration system, while a furnace produces heat through gas combustion or electric resistance. Some systems combine more than one heating method.
Why does my furnace start and stop repeatedly?
Short cycling can involve airflow restrictions, thermostat or control problems, safety limits, ignition concerns, or equipment sizing. A complete diagnostic is needed to identify the cause.
Should I repair or replace my heating system?
The answer depends on equipment condition, age, repair history, safety, comfort, efficiency, and repair cost. We explain the practical options after evaluating the system.
