When Does Putting in a Ductless AC Make Sense?

Monday, August 12th, 2019

ductless-system-with-technicianYou may already have some familiarity with ductless mini-split AC systems in Staten Island, NY. You can find them in businesses and in older apartment complexes. When you see what looks like a small-sized window AC up on the wall—and with no actual window behind it—that’s the air handler part of a ductless mini-split.

Instead of exhausting the heat from the room directly out the back of the unit the way a window AC does, the air handler of a ductless system connects through refrigerant and power lines to an outdoor condenser cabinet that looks the same as the condenser cabinet of a standard central air conditioner. This outdoor unit can connect to multiple indoor air handlers (from 4 to 8 depending on the capacity of the system) so cool air can be sent into rooms all around the house.

What “MERV” Mean for Air Filters

Monday, July 29th, 2019

air-fliter-cuMERV 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.

Don’t Try to Scrape That Ice off the AC Coils!

Monday, July 15th, 2019

frozen-acIf 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?

Monday, July 1st, 2019

water-dropletsWhen 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.

It’s Summer—But It’s Not Too Late for AC Maintenance!

Monday, June 17th, 2019

checkmark-greenThis week is the official start of summer. That doesn’t mean it gets instantly hot, of course. Sometimes summer weather starts in early, and sometimes the “June Gloom” hangs around for a stretch.

It’s the best way to have your AC “armored up” to make it through the gauntlet of summer heat.

If you haven’t had maintenance done … no time like the present! With most of the summer still ahead, you’ll receive the best benefits of maintenance and prevent major AC troubles.

Ways the AC Compressor Might Fail

Monday, June 3rd, 2019

compressor-in-ac-unitThere’s no such thing as a “non-vital” part of your central air conditioning system. All parts need to work well for the system to operate effectively and efficiently. But if any part were to be awarded the title “The Most Important AC Component,” it would be the compressor. It’s the literal heart of the air conditioner because it is what causes the refrigerant to circulate through the system. The compressor changes the refrigerant to a high-pressure hot gas that allows for the heat exchange process to start. Without a working compressor, an air conditioning system will function as nothing more than a large fan blowing around room temperature air.

The compressor usually lasts for the full life of the AC. In fact, it’s often a dead compressor that signals the end of the air conditioner’s lifecycle (around 10 to 15 years). However, a compressor might fail early—and usually it’s not worth the cost to fix it.

The R-22 Phaseout Is Almost Done—Time to Replace That Old AC

Monday, May 20th, 2019

wall-clock

The clock is running out for old air conditioning systems that use R-22 refrigerant. If you aren’t certain what the R-22 phaseout is or how it affects your air conditioning system, here’s a quick rundown:

R-22, sometimes called Freon (a brand name), is an outdated refrigerant blend that was used for decades in air conditioning systems. Because R-22 creates ozone-depleting substances, the US Environmental Protection Agency started a process of gradually phasing-out use of this refrigerant blend to replace it with R-410A (a.k.a. Puron), which is not only healthier for the environment, but is a more efficient refrigerant blend for heat transfer.

The phase-out is now reaching its conclusion. As of 2020, professional HVAC technicians will no longer be permitted to use R-22 for any repairs to air conditioning systems, even using reclaimed refrigerant. So this means…

The Difference Between Heat and Energy Recovery Ventilators—Revealed!

Monday, April 22nd, 2019

airflow-diagramThere are many ways you can improve your home’s indoor air quality and its ventilation. One of the most useful is the installation of an energy recovery ventilator (ERV) or heat recovery ventilator (HRV), devices which allow fresh air into your house without it drastically changing the indoor temperatures and placing more stress on the AC or heater.

We usually talk about energy and heat recovery ventilators together, but they aren’t the exact same device. When people are looking for better home ventilation, they’re often curious about what’s different between the two. We’ll explain ERV vs. HRV below.

Should You Turn Off Your Boiler This Summer?

Monday, April 8th, 2019

boiler-residentialWe haven’t yet reached the point where the warm weather will have settled in and our air conditioners will take over as the main comfort systems in our homes. But it’s still a good idea to start planning for that day. The first order of business is to arrange for air conditioning maintenance from a professional HVAC company in Staten Island, NY. You can rely on our technicians for this job—you only have to sign up for one of our maintenance agreements.

But what about your home’s boiler? Should you shut it down for the summer? Hopefully, you already know that you shouldn’t shut your boiler down in winter whenever you go on a vacation, as the pipes might freeze. But is it fine, even beneficial, to have the boiler shut down during summer weather?
