Overview
If you’ve watched home improvement shows and gotten tips on how to save energy, you have probably replaced your incandescent light bulbs with compact fluorescent or light-emitting diode bulbs. And you may have looked into your attic to check out the insulation and ventilation. You may also be aware that it’s important to seal the air leaks that cause drafts and learned that the best way to identify them is with a blower-door test. Unfortunately, you can’t rent one at the home improvement store.

But there is a solution: Have a home energy checkup through our Home Energy Solutions program. For a small co-pay, a technician will pinpoint air leaks and seal them, test your heating system, check your ductwork, assess your insulation needs and give you recommendations for additional energy-saving improvements that qualify for rebates. Whether you go on to do the work yourself or hire someone, you benefit from expert advice specific to your home.

Phasing Out HCFC Refrigerants to Protect the Ozone Layer

December 1, 2019
What you need to know when servicing or replacing an air conditioner in your home.

Read More

HCFCs and the Ozone Layer
The stratospheric ozone layer shields the Earth from the sun’s harmful ultraviolet radiation. Emissions of certain synthetic chemicals—including CFCs, halons, and HCFCs—destroy the ozone layer, and have created an “ozone hole” over the South Pole.

Through the Montreal Protocol on Substances that deplete the Ozone Layer, the United States committed to a collaborative, international effort to regulate and phase out ozone-depleting substances. While the US phased out of CFCs and halons in the mid ’90s, we now must reduce HCFC consumption in a step-wise fashion.

What are HCFCs and R-22?
Hydrochlorofluorocarbons, or HCFCs, are chemicals that are mainly used as refrigerants. Unfortunately, releases of HCFCs deplete the Earth’s protective ozone layer and contribute to climate change.

R-22 is an HCFC refrigerant that is often used in air-conditioning equipment. To protect the Earth’s protective ozone layer, the United States is phasing out R-22, along with other chemicals.

As the United States phases out refrigerant R-22, you will need to make informed choices when servicing, repairing, or replacing an existing air-conditioning unit or when purchasing a new unit. EPA has banned the manufacture of new equipment that contains R-22. As a homeowner, you need to consider and balance several key factors in your decision to purchase a new unit, such as energy efficiency, performance, reliability, cost, and the refrigerant used.

The lengthy phaseout period allows you to replace your air-conditioning equipment that contains R-22 when you normally would, for instance, if it becomes old, inefficient, or ineffective. Realizing that supplies of R-22 will become more limited and that the price may increase should also be factors. In the meantime, R-22 remains available for servicing equipment made before 2010.

Availability and Cost of R-22
R-22 is a refrigerant that is often used in air- conditioning equipment. Because R-22 depletes the ozone layer, production and import were further limited in 2010.

In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. The production (not use) of R-22 is being phased out. You are not required to stop using R-22 air conditioners nor to replace existing equipment.

The phaseout period provides time to switch to ozone-friendly refrigerants when you normally would replace your air conditioner.

In the future, R-22 supplies will be more limited and costs to service equipment with R-22 may rise.

Servicing Systems with R-22
You may continue to have your equipment containing R-22 serviced.

The most important thing you can do is to maintain your unit properly. Appropriate servicing minimizes potential environmental damage and maintenance costs.

It is important to select a reliable service contractor. Technicians must have EPA Section 608 certification to service equipment containing R-22.

Request that service technicians locate and repair leaks instead of “topping off” leaking systems. This protects the ozone layer and saves you money by optimizing the performance of your existing equipment.

It is illegal to intentionally release any refrigerant when making repairs. Technicians must use refrigerant recovery equipment during service.

Buying a New Air Conditioner
EPA has prohibited the manufacture of new air-conditioning systems that use R-22.
Systems that use alternative refrigerants that do not harm the ozone layer are available and will become more common.

New energy-efficient air conditioners save energy costs. Even if your air conditioner is only 10 years old, you may save significantly on your energy costs by replacing it with a newer, more efficient model.

Energy efficiency is measured by the seasonal energy efficiency ratio (SEER). The higher the ratio, the more efficient the equipment.

A central air-conditioner that has earned the ENERGY STAR® label is at least 14% more efficient than a standard new system and can save you money on your cooling bill.

ENERGY STAR® qualified systems are available for both R-22 and alternative (R-410A) systems.

Alternative Refrigerants
The most common alternative to R-22 is R-410A, a non-ozone-depleting HFC refrigerant blend.

R-410A is manufactured and sold under various trade names, including GENTRON AZ-20®, SUVA® 410A, and PURON®.

EPA reviews alternative refrigerants and maintains a list of acceptable substitutes for household and light commercial air conditioning.

It is illegal to intentionally release refrigerant substitutes when making repairs. Technicians must take efforts to avoid releases during service.

Onofreo Home Comfort Systems LLC installed a new ductless, mini-split air conditioning system in our home. Very completive pricing when compared with other area contractors.

Nick N.

Everyone in the office I spoke with was so friendly and responsive. They called to notify me that the technician was running late, so I wasn’t sitting around waiting.
Our Technician, Giovanni, was excellent.

Ellen L.

We recently had to replace our central Air Conditioning and received estimate from various HVAC specialists, including the one we currently have a service contract with. Shane, the sales constant, was by far the most professional, patient, kind, honest, and thorough person that I met with.

Christine K.

Bravo to Pat from Onofreo! He walked me through all the service needs for my hot water heater and heating ducts & vents. An overall fantastic experience and I will be calling Onofreo HCS for all future HVAC needs. Thank you 🙂

Carmen F.

Just amazing people even helped me with rebate paperwork from my electric company.Will use them again and so should everyone else.

Ralph S.

Anthony called prior to the visit. Arrived on time & found a capacitor was bad on our compressor. He went on to check the entire system to make sure it was running right, without me having to ask. Very friendly & explained everything he was doing. Kelly was also very pleasant to deal with on the phone.

Wayne S.

They were both very professional, informative and very neat and went out of their way to any other issues. I highly recommend them and hope their service lives up to the same.

John T.

Onofreo is an amazing company That is represented by excellent products and professional staff. When I first called them they were extremely responsive to my needs and took care of the initial concerns that I had with an old air conditioning system.

John S.

Excellent service and quick response. Also had what I thought was a leaking hot water heater but turned out something far less expensive. They responded back quickly and had everything finalized within 2 hours of my initial contact with their office

James V.

This company was an absolute joy to deal with helping me switch from oil to gas and taking care of every step of the process, from sales to installation to dealing with gas company. Kelly is a gem. Can not recommend enough!

Terri M.

The installation was installed neatly on the date scheduled and at a terrific price. We are completely happy with the professionally executed work.

Michael L.

We just had a ductless split unit system installed in 4 rooms of our house. The people at Onofreo are amazing to work with, from the owner Mark, to the office staff to the guys coming out and doing the work. The install happened much quicker than I anticipated and they were SO clean, I would have never known they were in my house cutting into walls, etc. The system itself is awesome – very quiet and cools down the house super quick. When Tom came for the consult, he told me I’d never want to leave the house again and he was right. Best thing we ever did! Thank you Onofreo!

Heather D.

Amazing to experience an oil to gas conversion with Onofreo! Efficient, fast, and beautiful work!!

Melissa B.

Anthony, Mark, and Kelly have helped install, fix and maintain our furnace and AC units for many years now — they are the best, and yes, we have tried the rest. But we will always call Onofreo from now on. Excellent work, done fast and reasonable rates — great people too.

John B.

Onofreo has proven themselves yet again to be the best in the business. My wife and I went to them a second time, this time to replace our Central AC unit. First of all, they came right out to inspect, then they gave us a price that was much lower than I had expected. The install happened very quickly and everything is perfect. Mark and his team are absolutely wonderful and I can’t recommend them highly enough. Truly a first class company all around. If you need work done, this is where you should start. Thank you for another great experience!

Joe B.

Mark and his team are the best. They are honest, transparent, hard working, professional and punctual. They answer all of your questions, even the dumb ones, and I had plenty of those. They removed my antique furnace and installed a complete heating system in 2 days as promised as well as a hot water heater on an emergency basis. They also wear masks. Call them. You won’t be disappointed.

Elaine M.

Had to change the zoning board, wiring to HVAC and thermostats on an 30 year old system . Responsive, on time arrival, fair pricing – true professionals. Was absolute pleasure to see how their engineer arrived on time, communicated everything he has done, and the work performed. Will definitely contact them again for anything HVAC related.

P K

The install was well planned and started on scheduled date. It required multiple condensers and 4 wall mounted units. The team was friendly, professional and worked non-stop through two very hot days directly in the sun. The install finished ahead of schedule. Cabling is very neat. Team cleaned up when finished. So, start to finish just as promised. The Mitsubishi units work very well and are extremely quiet. An overall A+!

Jeffery B.

I had an issue with hot water system. They were very fast to send someone out on the same day to diagnose the problem and quickly got in parts the next day to complete the job. Kept me closely updated on when a repair person would come to my place. Very happy I can shower again with hot water!

Monkol L.

The technician was very polite. He assessed the situation quickly but thoroughly and provided a honest diagnoses. He told me exactly what was wrong and needed to be done and he performed the job well because everything is working perfectly. I will call them for my future needs and recommend them if you do not have a HVAC provider.
