Hi,
I have a 1993 vintage Carrier furnace that has been cycling frequently and takes forever to reach the set temperature (probably 1-2 degree change per hour!). Yesterday the furnace stopped working so I changed the filter and reset which got it going again so it seemed like the furnace was not getting enough airflow from the returns. The filters I have been using are MERV 8 rated pleated filters. Today I switched out the MERV 8 filters for plain fibeglass filters and the furnace seems to be performing much better, not cycling as much and temperature raises 1-2 degrees in 10 min. Is it possible that the better quality filters were restricting the airflow cuasing my furnace to work harder?
