PSIG stands for “pounds per square inch gauge,” which is a measurement of pressure. It represents the pressure of a system relative to atmospheric pressure. In HVAC systems, PSIG is often used to measure the pressure inside refrigerant lines or tanks. If the pressure reading is zero PSIG, it means the pressure inside the system is equal to the atmospheric pressure outside.
just left us a 5 star review
Jonathan is highly technical, knowledgable, and efficient. I wish I had known his company years ago. I highly recommend Paradise for all heating and air needs.
Called Paradise on a Sunday(Father's Day) and got a call back and service/ repair the same day. They explained what was needed and did the necessary repairs. I have a nice cool home again.
Fast on time & courteous
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.
5 stars! Look nowhere else for all of heating and cooling needs. Jonathan is amazing - experienced, reasonable and reliable. Look nowhere else!
Great service, price, and quality workmanship! Highly recommend! I will use them again.
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.
Awesome customer service. Exceeded my expectations compared to past experiences with different companies
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.
Extremely nice, on time, helpful and explanatory. Very professional. Thank you
Jonathon, as always, provided great service! He is very efficient and honest. Thanks Jonathon, Charles
Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.
Amazing service and very helpful as well as willing to inform me of what was going on.
Jonathan has serviced our AC unit for many years and I continue to trust his expertise. I would recommend him to anyone seeking an honest and fair HVAC company.
Great service, very professional! Highly recommend.
Jonathan was very professional and knowledgeable, with a great personality. I will be doing business in the future with his company. I immediately signed up with the company’s annual service plan.
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.
Paradise company is very reliable and trusted. Jonathan is very knowledgeable and understanding. He replaced A C Unit in my home and since then it's working efficiently. I want to recommend this company for everyone
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!
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.
Always on time, easy to communicate, finest quality of workmanship and character, affordable pricing. Highly recommended.
Thank you Paradise Heating and Air for your quick response, great customer service and fair price!
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!
Most honest, knowledgeable and affordable HAVC company I've ever dealt with.
Jonathan and his staff were very communicative! Would highly recommend.
Jonathan was very knowledgeable and friendly. Appreciated his candor and non-salesy guidance. We will be using them again.
Johnathan and Christian did and amazing job and were well versed and knowledgeable about the unit. They fixed it in a timely manner and my house was cool again within an hour
We were very pleased with the service we received! The men were knowledgeable, honest, and timely. We would HIGHLY recommend this service!
Paradise has become our go-to HVAC company. We have used them for several smaller repairs and they always provides a reasonable price and didn’t try to upsell replacing our 30 year old unit before we were ready. Then, when we were finally ready to replace our unit we got quotes from Paradise and several other companies. Paradise was by far the best value not only in terms of price but also unit brand and warranty. We even ran all of the quotes through AI and his came in 1st in terms of value, price and ROI! Great company overall - can always trust them to provide great, high quality work and reasonable prices.
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
Professional, on time, fair prices, great job!
Jonathon and Christian did an excellent job! We would recommend them highly!
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!
Jonathan was nothing more than stellar. Very engaging as well as very knowledgeable at his profession. I would highly recommend to anyone looking for HVAC services.
Very prompt, respectful, thorough, and didn’t break the bank.
Very professional and knowledgeable. No need to look over their shoulder. Very satisfied with their work.
Jonathan was great to work with. He came within a couple of hours after I called at around 4pm. and had us operational around 12 the next day (because he didn’t have a motor for my condensor and had to get one the next day). Will definitely use him again.
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.
Did a very thorough job of servicing my system. Will use again.
Excellent service, very kind, and very reasonably priced. Went the extra mile to help me out. Really appreciate you guys!
Jonathan to the rescue! A quick response saved us from a miserable night. Jonathan had us fixed in a matter of minutes! Highly recommend!
We've been doing a complete renovation of our family home of 30 years to sell and retire. We also needed to make sure we had adequate insulation and have the ductwork inspected. I called Paradise Heating and Air, and found that this was a service they could provide. They were very responsive. I had an estimate within a few days and the job completed the following week. They fixed anything that could become a problem and blew in the amount of insulation to meet the current Hoover building code. Jonathan was so friendly, explained everything that was done and the cost was very reasonable. In fact he talked me out of insulating an area that wasn't really needed!!! I couldn't be happier with the service, and feel good that everything is secure and to code. I highly recommend Jonathan and Paradise Heating and Air!!
Being a first time customer I was extremely impressed with how punctual and professional the technicians are. I highly recommend Paradise Heating and Air
Excellent service, on a Sunday, highly recommend :)
Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.
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.
