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.

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. The weather here in Staten Island is already climbing up past warm and will soon reach hot—so we hope you’ve already had your annual air conditioning maintenance done. 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…

Skipping Spring AC Maintenance Can Mean Plenty of Wasted Dollars

Should You Talk to Your Maintenance Tech About Getting a New AC?

Monday, March 25th, 2019

air-conditioning-recyclingIn our last post, we put up a friendly spring reminder: have your air conditioning system professionally maintained! There’s nothing better for a hard-working central AC than to have an annual inspection and tune-up. It means better performance, fewer repairs, energy-efficient operation, and a long system life.

But let’s talk about that last advantage a bit more: how long can an air conditioner keep working? Maintenance extends its service life, but no level of diligence can make an AC work forever. Your home’s current air conditioner will eventually need to be replaced. Is this something you should discuss with your HVAC technician during maintenance?

Spring Is Almost Here: Time for an AC Tune-Up!

Monday, March 11th, 2019

The time between winter and summer is when HVAC technicians help customers get their air conditioning systems ready for hot weather. Technicians are dealing with fewer emergency calls for heating repair, and that makes it much easier for customers to schedule an annual AC inspection and tune-up.

We strongly encourage you to arrange for your annual AC maintenance services early this spring. It’s okay if you do it a bit later, but please don’t skip it entirely!

autumn-backgroundWe aren’t asking you to show pity for your air conditioner: it is, after all, a piece of machinery. It doesn’t have feelings.
