Most common questions used to investigate
Is it turning ON?
Check the power switch. Is it turned ON?
Check the thermostat settings. Is it configured properly according to the required temperature?
Check the main gas inflow pipe. Is it clogged or closed or is the valve OFF?
Check the igniter. Is it working properly?
Check the filters. Are they dirty or clogged with debris?
Is it producing enough heat?
Check the thermostat controller. Is it set to a proper/high temperature?
Is it producing enough cool air?
Check the thermostat controller. Is it set to a proper/low temperature?
Is the HVAC continuously running?
Is the thermostat configured to a really high/low temperature?
Is the HVAC system producing noise that is not normal?
Is there a smell of gas coming from near the HVAC base?
Common conclusions
First turn the switch as it acts as the master power controller.
Simply change the settings by changing it to either hot or cold according to the temperature requirement.
If clogged clean the pipe yourself or contact a professional and if the valve is turned OFF, simply turn it ON and try again.
The cause for the malfunction may be a faulty igniter. Replace it yourself or contact a professional.
Clean the filters or replace them with new ones as they may block the air flow.
Contact the original manufacturer or a professional to get the system diagnosed and fixed.
The thermostat controls the temperature so reconfigure the thermostat using the controller to get greater heat.
Clean the filters or replace them with new ones as they may block the flow of hot air.
The problem may be that the HVAC cannot produce enough heat for the room due to the area being much larger or there being some open windows or doors.
The thermostat controls the temperature so reconfigure the thermostat using the controller to get cooler air.
Clean the filters or replace them with new ones as they may block the flow of air.
The problem may be that the HVAC may be lacking cooling agent, contact a local technician to get it refilled. Another problem may be that the system cannot produce enough cool air for the room due to the area being much larger or there being some open windows or doors.
When the controller is set to a higher/lower temperature value the longer the work cycle. So first change the temperature setting to a moderate level and try again.
The problem may also be with the room being large in size or a door open from which air is passing. This may lead the system to work for longer periods to regulate the temperature. Additionally, it may be due to a broken thermostat or limit switch. Contact the original manufacturer or a professional.
Contact the original manufacturer and file a request for service or hire a professional to get the HVAC diagnosed as the problem may be with loose bolts or expanding ducts or something stuck in the vents.
First turn the main gas valve OFF as there may be a leak, then contact a professional to get the gas connections checked.
Contact the original manufacturer and file a request for service or hire a professional to get the system diagnosed.
