Did You Know . . .
- During winter, indoor humidity is much lower. Increasing indoor humidity by installing a humidifier can help reduce COVID lifespan
- Most A/C and Furnace equipment manufacturers require regular maintenance to preserve your warranty (just like a new car)
- Regular pre-season maintenance prolongs equipment life, reduces repair costs, and can
reduce annual utility costs by hundreds of dollars - During last summer, A/C and Furnace manufacturers experienced equipment shortages resulting in delaying replacement of failed A/C systems. If there is a COVID surge this winter, manufacturing and service personnel could be affected and prolonging equipment and service response times. Be proactive and have your heating equipment checked to avoid possible extended outages at inconvenient times in the cold of winter.
