Line Set

« Back to Glossary Index

Line sets are the copper refrigerant pipes used in split HVAC systems to connect the indoor evaporator coil to the outdoor condenser unit. They consist of two pipes: a larger suction line, which carries the refrigerant in its gaseous state back to the condenser, and a smaller liquid line, which carries the refrigerant in its liquid state from the condenser to the evaporator coil. Proper sizing and installation of the line set are crucial for system efficiency and performance. Factors such as the distance and elevation difference between the indoor and outdoor units influence the required size and insulation of the line set. An improperly sized or installed line set can lead to reduced efficiency, poor cooling or heating, and even system failure.

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!

Jessica Ahrabli

Johnathan and his son were excellent in installing a new hvac system in our home we had to have redone. They also fixed our upstairs unit and blew new insulation in our attic. They kept our home cleaned up as well. Great communication, very prompt and super friendly. We are so happy we found them!

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!

john DiOrio

Jonathan and the Paradise team are the best. In my 50 yrs of home ownership, I haven't had anyone I've trusted more. My wife and I downsized recently, and Jonathan helped us upgrade old to new heating & air units, including thermostats and attic insulation. Paradise Heating & Air is a great company... glad we found them years ago.

He was on time and got the insulation job done quickly. I had contracted with another company who no-showed twice, so being able to call Paradise and get it done within a short time was great.

Chris Holland

Jonathan and the whole Paradise staff are professional, courteous, and fast. I had a system failure, and they were able to get to me quickly and diagnose the problem. Through Jonathan's research he discovered my system had a warrantied part needing replacement and saved me $1600. I would HIGHLY recommend Jonathan and the Paradise crew and will be using again!

john norris

Johnathan and Matt very knowledgeable and professional. Addressed my problem and fixed at a very reasonable price. Would highly recommend.

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!!!

Blake

We recently bought a home and right away one of the AC units failed. Of course it was after hours (do AC units ever fail not after hours?). I called Paradise Heating and Air and they dispatched quickly, diagnosed the problem, and had us cool and running again before the kids were even in bed. Jonathan figured out the issue fast, and the quality of work and the cleanup afterward were truly noticeable. They've become our go-to HVAC company, always a notch above on service and workmanship. If you need emergency AC repair or any HVAC work in Vestavia Hills or anywhere in the Birmingham area, don't hesitate to reach out to this team. Love working with them!

Excellent company! Jonathan and Matt were professional, friendly, and extremely efficient. They had my HVAC system replaced in 4 hours! If my other unit ever bites the dust, they will be the ones I call for a new one!! I highly recommend them.

Rory Chrane

Update: May 2026 Paradise came and serviced my business and home this week per the service agreement I asked them to sign me up for. Excellent trustworthy people and processes yields a top level result. You can trust them too. Call them and see what I mean. 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.
