Call for no heat. Found furnace trying to light but would not stay lit considering age and symptoms likely flame sensor has a lit bit of debris on it. Recommend furnace tune up. Furnace tune up performed refer to furnace health inspection report. Flame sensor cleaned and equipment began to run appropriately. Furnace does have a little bit of a higher static pressure reading. But overall furnace is burning clean and efficiently with no electrical problems observed. System does not have a surge protector or a wet switch especially given close proximity to main drain it would be a good idea to help prevent any water damage if there was ever a draining related issue with plumbing. No air purifier to help keep system and homes air clean and pure. Recommendations refer to estimates.
