MERV may look like a misspelling of the name Marv, but these four letters are vital for understanding the air filters in HVAC systems designed to trap particles from circulating through a building. Not all filters are the same: the simple panel filter on your HVAC cabinet is designed to stop large contaminants like dust and lint from getting into the system, while the HEPA filters used in hospitals are powerful enough to stop the movement of bacteria and viruses. MERV is the rating that explains the filtration power of the filter. The higher the MERV rating, the tighter the filter weave.

Monday, July 29th, 2019Don’t Try to Scrape That Ice off the AC Coils!
Monday, July 15th, 2019
If you’re reading this, it’s because you already know that ice forming along the indoor evaporator coils of your air conditioning system is a bad thing. We’re glad to hear it. Too many homeowners make the mistake of thinking that ice appearing on the coils is just a normal part of how an air conditioner runs. It’s not. When you see ice or frost on the coils, it means something is wrong with the AC’s ability to draw heat from the air.
However, the solution to this problem isn’t scraping the ice from the coils. No matter what tool you’re thinking of using to remove the ice, please put it away. A frozen coil requires calling for air conditioning repair in Staten Island, NY from professionals.
Why Is Water Dripping From My AC?

When an air conditioner is running, it makes a number of sounds as part of its basic operation: the hum of the motors running the blower fans, the low whirring of the compressor when it starts a cooling cycle, the whoosh of air moving through the ductwork—and the sound of water dripping from the inside unit.
Why is there water in your air conditioning system in the first place? It’s part of the cooling cycle, but the AC is designed to keep this water from getting out of the cabinet and dripping into the house.
But no part of a central air conditioning system can operate 100% free of trouble 100% of the time. When you see water dripping from the indoor cabinet of the AC, you’ll need to call for central AC repair in Staten Island, NY right away.
