« Back to Glossary Index

PSI refers to “Pounds Per Square Inch,” which is a unit of pressure measurement. It describes the amount of force applied over one square inch of area. In HVAC systems, PSI is commonly used to measure the pressure of refrigerants in different parts of the system, as well as the pressure in compressed air systems or gas lines. Proper PSI levels are critical for the efficient and safe operation of HVAC equipment.

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.

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!

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 🥰.

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

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."

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!!!

We were in dire situation last last summer when our AC system went off with no repair really feasible. We took some time to shop around despite of awful heat in the house. Johnatan from Paradise Heating and Air is honest, articulate, skillful professional. He offered the best value and cost, the easiest ways to pay, and great service plan. I would recommend everyone to contact Johnatan and Paradise Heating and Air for the AC service.

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.

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!

Had what I thought was an issue with my furnace at MIDNIGHT and was in a panic trying to decipher what I thought was an error code. Called numerous places advertising 24/7 assistance and no one could/would help. Jonathan Perkinson with Paradise actually called me back, explained it all to me and kept me from shutting it all down on a cold night. So kind and helpful!!! Highly recommended!

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!
