What People are Saying About Us

Don’t just take it from us, let our customers do the talking!

I thought I would drop you a line to tell you what a wonderful product you have. 

I live in southern California just outside Los Angeles in the San Fernando Valley. The area where I live sometimes gets to 100 degrees during the summer and down to 40 degrees during the winter. In our Fall and Spring it can be 75 degrees during the day and 40 degrees during the night. This would be a challenge for any air conditioning and heating system.

My house is a two level house approximately 2800 square feet. It is nearly evenly split upstairs and downstairs. Three of the four bedrooms are upstairs. After the 1994 earthquake my house was “Red Tagged” meaning we had to take it down to the two by fours and reinforce the foundation.

My house was always difficult to balance heating and air conditioning the two levels. The A/C contractor wanted to zone the house and put in two separate systems, one upstairs and one downstairs. This made sense, but was very expensive and we were running out of rebuilding funds.

I happened to read a Popular Science review on your system (I believe your company was Enerzone at the time). It sounded cool so I called Jerry to discuss my situation and see what he thought.

We designed a Five zone system; each bedroom had it’s own zone plus one zone for the Living Room, Dining Room and Kitchen. Since Fall and Spring nights were cool, we designed a system to bring in outside air when the outside temperature was less than the temperature setting of a zones thermostat.

I installed Two Airzone panels SPP-6 and SPP-2, plus one panel of relays to connect to the EWC zone control panels. I have 14 Flexdampers of various sizes to complete the zoning.

Over the years our single Lennox Forced Air unit and condenser has been able to keep us cool or warm and we minimized our power usage. We had to replace the Lennox in 2010.


My zoning system has worked since the nineties. I have only had to replace a couple of 24 Volt transformer over the years. This year the EP-1 vacuum pump finally gave up (Rest in Peace).

My Air Conditioning maintenance company that services the Lennox Forced Air unit every year suggests I replace the Zoning system with their mechanical damper system. When I ask if the could match the reliability of the current system, they always answer no.

Thank you for many decades of great comfort.”

“Just replaced my old Synchronic damper motor with a new Belimo motor and now my zoned heat is working great. I was unsure of what I needed, but Jerry worked with me and get me set up with all the adapters and equipment I needed. I will definitely recommend RetroZone to my friends and family, and willl happily use them again if needed”

“Great product, and excellent service.  The item took minutes to install and worked perfectly.  Don't pay more than necessary...so buy this one.  You won't regret your decision.”

“This is the second time I have used Retrozone Inc and I am truly a satisfied customer!

They are prompt in answering my call, answering my questions and determining the correct part/product that I needed.

I tried to use local sources for the parts and had to make a minimum purchase and/or be an active contractor.

I love their customer service!”

Retrozone products and customer service absolutely amazing. Technical help to choose the correct replacement got it right. Price very fair and shipping immediate. Needed a little help installing and was offered above and beyond support. Damper motor far superior than the original. Can't wait for something else to fail to do business with Retrozone again.

Great product - RZ3-1M.  Got a 2-zone system on the second floor of my home and after 10 years the Honeywell motor on one zone stopped working, this works perfectly in its place.

Their tech Jerry is well informed and bends over backwards to help making their customer service second to none. Sure their products are well priced and good, but customer service is what really sets them apart.
