Most HVAC units slow down and sometimes even stop working altogether when there is a lot of obstruction around it.
Remember that these heating and cooling systems depend on free airflow to work.
Numerous obstacles interfere with the free flow of air, meaning that the HVAC unit either overcompensates and wastes energy in the processor shuts down. For this reason, it is only reasonable to ensure that your air conditioning unit and the furnace have no obstructions. The furnace needs to have clear space for free airflow and prevent avoidable accidents when and fire breakouts. Putting flammable items around the furnace can cause accidents and endanger people and pets’ lives, not to mention that it may destroy a lot of valuable property. Most people do not realize when they accumulate stuff around the furnace, especially when they store their miscellaneous items in the basement. This may be very convenient in summer because the furnace is practically unused and the air conditioner is mostly on; there is a chance that you will forget to move them when the weather changes. This can be disastrous. Do not take chances and avoid putting items near the furnace regardless of whether it is winter or not. Instead, clean the furnace and its surroundings in readiness for the next season’s use. Note that dust and lint accumulation in the furnace can equally affect the furnace’s efficiency when they clog the filters. Ignoring to vacuum and clean will mean changing the filters sooner than you should have to. Avoid wasting your filters by cleaning as regularly as you can and only change the filter when it is necessary.
