Have HVAC Questions? Ask an HVAC Expert for Answers
Most heating and air conditioning questions require some diagnosing of the specific situation.Very few are one line asnwers .To be professional and provide you with an accurate answer may require me gathering some details such as model number on units and specifics on the issue at hand.To tell you to replace a part or exactly what is wrong with your unit without knowing this information would not be doing you justice ,would be less than professional on my end and a guess at most.Please provide information I ask for so that I can provide accurate answers to your specific equipment and situation.
. 1. What is model on thermostat?
2. Have you checked for batteries
3.Do you have a volt meter for troubleshooting?
Most digital thermostats have a front cover and a sub base. Do you see a seam mid ways from front to wall. If you have a pic would help.
