Capillary Tube System

« Back to Glossary Index

A capillary tube system is a simple type of refrigerant control device used in HVAC systems, typically in small cooling appliances like window air conditioners or refrigerators. It consists of a long, thin tube with a very small internal diameter, through which the refrigerant flows. The tube’s narrowness and length create a resistance to the refrigerant flow, controlling the pressure difference between the high-pressure side (condenser) and the low-pressure side (evaporator) of the system. This pressure drop ensures that the refrigerant enters the evaporator at the proper rate and pressure for efficient cooling.

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.

Jason Motley

I would highly recommend Jonathan and Paradise Heating and Air. I called multiple places to get quotes on replacing my two older units. What sets Paradise apart is Jonathan took the time to explain my current system, as well as pricing comparable new systems. Not once did he try and sale me the bells and whistles that did not align with what I was replacing like the other businesses. He was not pushy and his prices can't be beat. You can't go wrong with Paradise Heating and Air and they will be my shop for any HVAC needs moving forward. Thank You for being fair and honest.

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.

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.

Karen

Johnathan was great! We had a moisture problem in our kitchen cabinets that were on an interior wall. He spent a good amount of time figuring out what was going on, gave us a solution and answered all of our questions. A very good experience!

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!

David Brainerd

Jonathan did a great job. Highly recommended.

Kellie L

I can not say enough great things about Jonathon and Paradise Heating and Air. From the moment they answered the phone I knew I made the right choice. This team is top notch! I called on Monday for attic insulation, Tuesday Jonathon came out and spent time showing me what I needed and Thursday the job is done! Clean, professional and treated me and my home like family. I will be using them for EVERYTHING they specialize in. You CAN NOT GO WRONG with this company! 1000% satisfied and never have been so happy to spend money on insulation 🥰.

Melanie Authement

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

Ashley Ponter

We were very pleased with the service we received! The men were knowledgeable, honest, and timely. We would HIGHLY recommend this service!

Cynthia Belyeu

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!

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.

VWC

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

Brian L

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

Adam Myers

One of our AC units decided to give up, or so we thought. We had several companies come out and give us a quote to replace our unit, all exceeding $13k. Paradise came out, and instead of just giving a price to replace it, they asked if they could tinker with the equipment. They had it fixed within 10 minutes!!! Paradise gave us a quote so we have an idea of the cost for when this ancient unit ACTUALLY dies, and it was $3k-$8k cheaper than our other quotes!!! They could have easily just given us a price for a new unit like everyone else. I appreciate that Paradise put forth the effort to figure out the problem, and saved us THOUSANDS!!!

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.

Marianne Herman

Exactly what I needed!

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.

Pam Cain

Great, fast and professional service always!!

DIONDRA ROBINSON

If you are having any HVAC issues please do not hesitate to call Paradise Heating and Air. Mr. Jonathan and his team were quick and provided answers to all my questions. I appreciate how quick they came out and fixed my issue being that we have had some extremely hot temperatures lately. I look forward to working with them in the future. I will be recommending them to anyone who has an issue. Thanks again to Paradise Heating and Air.

J Harrell

Katherine Marshall

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

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!

Ramona Martin

Trustworthy and honest! I'm so thankful for the service I receive from Paradise Heating and Air. I am a repeat customer because I know Jonathan will not try to sell something I do not need. He explains any issues in detail leaving the decision up to me on whether or not to replace a part. Jonathan takes his time to make sure everything is in good working order before he leaves.He truly cares about his customers. I highly recommend keeping your unit(s) serviced twice a year. I am seeing the benefits on being proactive with this. It's totally worth it. I cannot rave enough about the customer service you receive from Paradise Heating and Air. Call them!!!

Andrea Martin

5 stars! Look nowhere else for all of heating and cooling needs. Jonathan is amazing - experienced, reasonable and reliable. Look nowhere else!

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.

Pam Bennett

I can not say enough amazing things about my experience with Paradise - most importantly, about JONATHAN PERKINSON! He is super knowledgeable about any and all HVAC systems, and he answered all my questions - he actually went above and beyond my expectations. I am excited about this company bc I have tried SEVERAL in the Birmingham area - and I’m telling you - this is the company to use and Jonathan is the one specifically that I will be calling again and again!

A.K. Powell

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

Steve

Always polite. They were at my house at 8:30 pm making sure we had cool air.

Audray Jones

First of all they are very courteous people. Secondly they gave me an appointment asap and was there right on time in which I was able to keep track of the arrival by text messages. They diagnosed the problem and it was resolved in less than 30mins. I am truly grateful for Paradise Heating and Air. Thank you for your service. Side note: they chose the best name for the company. I was in Paradise after the repair lol

Jonathan and his crew are always quick to respond and on time. They always help me to understand what is going on with our AC and heating units. I get a concise explanation of what needs to be done. I have always gotten an honest answer about my current units and I have never gotten any pressure to replace the equipment that did not need replacing. It feels great to be able to trust the information you get from the people looking after your HVAC equipment, and that is what we get from Paradise. T. Marvin

Mark Hamblen

Did a very thorough job of servicing my system. Will use again.

Zac Goozee

Jonathan and team are hands down the best folks I have ever worked with in the home services industry. Reasonable prices, high quality work, great communication and responsiveness, 5 stars all around. Highly recommend.

Ruthie McNeil

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!!!

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.

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.

Nae Nae

I’ve used them several times now and they are always quick to respond, very polite and honest. I would highly recommend them.

Misty Hughes

I had my new unit installed about a week ago. Johnathan was the best. It was effortless , perfect workmanship , on time. Explained everything! Thank you Paradise !! FIRST RATE. TOOK CARE OF ME ASAP. WILL USE IN FUTURE FOR NEW UNIT

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!
