Are you there?

 

Have you changed your air filter recently?

Ask Your Own HVAC Question
HVAC Technician: Mr. Jeff Pearson, Mechanical Engineering Technologist replied 8 years ago
The reason I ask is that it is very common that when the air filter is replaced the cover door does not get put back on exactly right and this prevents the whole system from turning on.
