Background: A Florida family was having to deal with low-quality air and regular replacement of the HVAC system. The old filters were not giving the necessary filtration and the HVAC system was working too hard.
Challenge:
The air was full of dust, pollen, and pet dander.
As the HVAC system was under too much pressure, it led to increased energy consumption, breakage, and random repairs.
Solution:
Suggest using a 14x28x1 air filter.
The filter is designed to be highly efficient and collect most of the suspended particles in the air.
Additionally, it is capable of making the HVAC run at its best by reducing the level of friction it has to experience.
Results:
Cleaner Air:
No more allergy attacks, and the air smells fresh.
Better HVAC Efficiency:
The system ran like a well-oiled machine.
Use of less energy and fewer week-by-week cycles.
Saving Money:
60% less maintenance cost on HVAC systems.
The lifespan of the HVAC system was stretched, and only a few repairs were needed over time.
Takeaway: Swapping the 14x28x1 air filter has upgraded the air quality and the HVAC system's performance, thus just one simple step is enough to have long-term savings as well as the pleasant living environment.
