Spine-Fin™ coil

« Back to Glossary Index

A type of outdoor coil used in HVAC systems, made entirely of aluminum and featuring a patented Spine Fin™ design. This design consists of a tube surrounded by a dense network of spiny aluminum fins, which increases the surface area for heat exchange. The all-aluminum construction makes it highly resistant to corrosion, and its enhanced heat-exchange capability improves energy efficiency compared to traditional copper-aluminum coils.

We have had Jonathan and his capable team working on our A/c and Heating for several years. They are punctual, well mannered and reasonably priced. The work they have done including an A/C replacement has always been outstanding. Plus, we have appreciated their problem solving skills in helping our remaining old units get along from year to year. We are so grateful to have them a phone call away!

2025 UPDATE: I needed Jonathan service on Friday, April 3rd. I called his office at 6:40. Jonathan arrived at my home by 2 o’clock that afternoon. Got my unit back up and running in less than an hour. The team at Paradise heating and cooling. Always provide exceptional, customer service and expertise. As long as Jonathan is in business, I will continue to do business with him. "I was so impressed with Mr. Jonathan from Paradise Heating & Air! They were incredibly respectful of my home, even wearing shoe covers. They were punctual and kept me informed every step of the way. Mr. Jonathan took the time to explain the issue clearly and simply, without any confusing technical terms. They offered several options and let me decide what was best for me and my budget. I really appreciated that they didn't try to oversell me on something I didn't need. It's clear that Mr. Jonathan is knowledgeable and truly cares about their customers. I highly recommend Mr. Jonathan and Paradise Heating & Air to anyone looking for reliable and honest HVAC service. It's refreshing to find a company you can trust."

I was fortunately able to get an appointment for the next day. Jonathan & Austin were prompt and kept me advised of their arrival. They quickly found the problem with my "heat" and were able to fix it without problems. They were very friendly and professional, and I felt that their pricing was fair and reasonable. Thanks again, Guys! UPDATE: I once again had a very good visit from Paradise Heating & Air - they are very prompt and reliable and do an efficient job - thanks once again! I definitely recommend these nice guys!!!

Kyle & Joanna Baker

Jonathan was fantastic to work with! We had multiple quotes and opinions on some work we needed to get done and his recommendations and quote came in best and he had some recommendations others did not make that make us feel like he really cared about doing the right thing and really inspected our hvac situation. Jennifer and Gracie were also stellar! Will call them back and recommend to our friends!

Linda Thompson

Jonathan and his helper were awesome. Keeping us informed as to what they were doing as they replaced our heating and air units. They were pleasant to have around and did a great job. They not only left the areas clean they hauled off all the old equipment. We would highly recommended them to everyone.

Yan Zhu

Jonathan came by and discussed my problem with me. He was professional and gave me helpful suggestions. He did not even charge me for his time. It was a pleasure to work with them, please give the company a try.

Amanda Horsley

These guys did great work for us! Installed a new HVAC system at a competitive price, were very respectful in my home, neat, and incredibly helpful. All around just a great experience.

Scheduling was super easy and they were able to work me in quickly. Jonathan was so nice and explained things to me in a way I understood. They were also very quick but thorough

Rory Chrane

From the first phone call, I was impressed, I spoke to Jennifer and on a follow up call, I spoke to Gracie. Both are related to the owner Jonathan who came out today and gave me a breakdown and an idea of what is needed and proposed how to go about doing a mini split, which I’m excited to get done, so much so that I wanted to give a review, even before the work begins which I’m sure will be excellent. He recommended a good brand Mitsubishi and explained why he chooses them, giving a very detailed explanation. Jonathan was very personable and efficient and I look forward to the job being completed and future business with this company.

VWC

Amazing service and very helpful as well as willing to inform me of what was going on.

Katherine Marshall

Extremely nice, on time, helpful and explanatory. Very professional. Thank you

Mary Cavett

Jonathan was great - AC suddenly went out and he was able to get over in 30 min and get it working again! Very knowledgeable and nice!

Jonathan provided excellent service and was extremely knowledgeable. He had our heat up and going in no time and also helped us with setting up functions on our thermostat while he was here!

Jon Hinds

On time, explained everything very well. Came up with come options to repair my system rather than replace. Thank you.

J Harrell

Dana Gaudet

I recently had this company come out to my home because my unit wasn’t working, they had someone out the same day. Jonathan was extremely professional and knowledgeable, definitely recommend this company!!

Cheryl Kruse

I highly recommend Paradise Heating and Air. I contacted them to give me an estimate on adding more insulation to my attic. They were super responsive. They came out, gave me an estimate that I felt was very reasonable. In a very short time I was on their schedule. They showed up at the time they told me they would and they did a great job!! They even took care of the areas that were leaking heat. They are very personable, great to deal with. I am super pleased.

Ralph Ozley

Jon showed up as planned and committed to. A big plus was that he had the components on his truck to fix the broken part. Had my heat running after a 1 hour service call. Yes, I would recommend Paradise Heating and Air ...5 Star rec.

Christine Wilcox

They were great. Came out on a Thursday and looked at my system. Went over all of my options of repairs or replacements. Explained both the advantages and disadvantages of both options in detail so I could make an informed decision. Came back out the following Monday to do the work. Very friendly and knowledgeable staff.

Cynthia Gillantine

Very professional, courtesy and helpful. We needed a part but no pressure to buy it. We will use them again.

Kevin

Thank you Paradise Heating and Air for your quick response, great customer service and fair price!

Brian L

Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!

Nancy Hollaway

Our AC was struggling a bit. Had another HVCA company come check it out first. Their recommendation was a whole new replacement unit. Bare minimum a $6000 repair job. Got a second opinion from Jonathan’s company, Paradise. All the unit needed was refrigerant. Saved us thousands !! We would recommend Paradise every day of the week and twice on Sunday.

samuel wilson

Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.

Chris Mauck

Came out same day and explained the problem I was having and how best to fix it, and also what to look for to get ahead of any future issues before they get too bad

Lauren E Means

Paradise Heating and Air was great to work with—professional, on time, and very thorough. They communicated clearly throughout the entire process and were upfront about pricing and exactly what they discovered was wrong. I’m very pleased with their service and will definitely use them again. Being on time was a huge plus as well!

Mary Williams

Great experience!

Peter Wald

Routine service plus setting changes plus education plus rec's for the future. Spent much more time than normal to satisfy my real needs.

James Coco

Jonathan to the rescue! A quick response saved us from a miserable night. Jonathan had us fixed in a matter of minutes! Highly recommend!

John DiOrio

Jon and his team have renewed my faith in the HVAC industry. They service two homes with aging Heating & Cooling systems, and they've gone above & beyond in both cases. From surveying the attics for proper insulation, to accessing the basements and crawl space for any issues that might need to be addressed, I'm confident I'm in good hands with Paradise Heating & Air.

Kofi Creme

My unit was not working and they were working with my relatives. I asked if they would take a look at mine and they did with no problem. They told me what the problem was an within 2 days they had my unit up and running!

Pat Turner

If only all of our consumer needs were met like the service provided by the team at Paradise Heating and Air. From the very cordial and helpful Paradise employee who answered our after-hours, weekend phone call to the technical service provided by Jonathan and Matthew on Monday - we couldn’t be more pleased. We were informed every step of the way via text of all pertinent information including: scheduled appointment time, tech arrival time with the id’s of technicians who would be performing the work. Jonathan and Matthew arrived five minutes earlier than the one hour scheduled window (no no-shows here), did what they had to do and didn’t use weaponry to determine labor costs. In a land where customers have seemingly been disregarded and led to die, the folks of Paradise have obviously seen themselves and decided to do things a different and better way.

Monti Pres

Wonderful

Amy Graham

Jonathan was highly recommended and came by to look at a situation I had. He spent time looking all over my attic and my system. Had recommendation, seemed knowledgeable about my problem. Very courteous!

Printella Thomas

Wonder job Persistent and thorough in evaluating the problem and correcting the problem

Dave Meyer

I was extremely impressed with Paradise Air and am very glad I found them. I have a very old HVAC system they needed some ducts and a condensate pump replaced. They were extremely thorough and clearly explained everything they planned on doing. The price was excellent given how much work they had to do in the crawlspace and the extra time they spent with me advising me on how to get as much out of my old system as I could. They weren’t there to try to sell me a new system. They were there to repair what I asked them to at a reasonable price and help me extend the life of my current system. I won’t even think of calling anyone else from now on.

Brian Motley

My unit for upstairs had a major leak in the evaporation coils. Jonathan and Matthew came over and spent an hour here investigating and giving me my options. I decided to replace the whole unit and they were here on a Saturday replacing the unit. The knowledge that Jonathan possessed was second to none. The experience was excellent I will be using them again and I highly recommend them.

D. C. Smith

Replaced a furnace vent pipe and roof cap, Jonathan and Matt were competent technicians and explained everything to me clearly and the quote and the final price were the same. comparing quotes, they were very competitive and provided a high degree of professionalism on the job. Thank you very much.!

Polly Norris

I honestly cannot tell you just how highly I recommend these folks. Five stars are not enough! They are friendly, professional, very competitively priced and a real pleasure to work with. I've had them out twice, once for a split unit in my sunroom and then today for my main unit and both times they did an exceptional job.

Steve S

I had paradise come out to get me started with their paradise maintenance package, and had them take a look at my attic because we had concerns with our insulation not being adequate. They didn’t try to over sell work I didn’t need, and were honest with what exactly was needed to get us back on track. Techs Jonathan and Matthew came out for the initial inspection and service and came back to do the attic insulation. They were patient and knowledgeable (I ask a lot of questions) and took their time. They found all the places that my system was leaking (out and in) air, fixed them, and then filled the attic. They kept the house clean and were respectful and had great attitudes the entire time. They have definitely earned my business, and I would recommend them to anyone looking for HVAC work. They are AWESOME!

Perry Koonce

Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.

Melanie Authement

Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough

Daniel Maddox

Jonathan and the guys did a fast and efficient job fixing our ac. Always a worry when it goes out at the start of summer in Alabama. I highly recommend paradise heating and air to fix your ac problem. Communicated arrival time, explained the issue thoroughly, also didn't break the bank! Thanks again paradise!
