Ways the AC Compressor Might Fail

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

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R-22, sometimes called Freon (a brand name), is an outdated refrigerant blend that was used for decades in air conditioning systems.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!

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?

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.

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

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?

February 25th, 2019

tankless-water-heaterSaying goodbye is tough. You may not think of saying goodbye to a major appliance in your home as difficult.

Heater Starting to Lose Heating Power? Some Possible Reasons Why

February 11th, 2019

dog-under-blanketYou just want your heating system to get through the rest of the winter and into spring—but now it’s showing signs that something is wrong. You’re not getting the amount of heating you expect or need from the system, and you find yourself pushing up the thermostat higher and higher than normal to try to make up for it.

First—stop adjusting the thermostat. If you’re doing that, something is wrong with your heater that needs heating repair in Staten Island, NY. Trying to force it to work harder by changing the thermostat setting will probably just worsen the problem, even leading to a full breakdown.
