The wet bulb temperature is the lowest temperature to which air can be cooled by evaporating water into it at a constant pressure. It combines the effects of both heat and humidity, representing how cool the air feels when evaporation occurs. This measurement is often used in HVAC to assess cooling processes and is crucial for designing efficient systems to maintain comfort and safety.

just left us a 5 star review
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
Paradise Heating and Air are the BEST in the area! They’re very responsive and adapted quickly to our needs. Highly Recommend!!
Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.
Jonathon and Christian did an excellent job! We would recommend them highly!
Great company to work with AGAIN! The minor issues found were carefully explained and resolved. We setup a biannual service plan to keep this 20 yr old house in tip top shape. This is the company you need to handle your HVAC needs.
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!
Always on time, easy to communicate, finest quality of workmanship and character, affordable pricing. Highly recommended.
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.
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.
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
Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!
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
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!
Routine service plus setting changes plus education plus rec's for the future. Spent much more time than normal to satisfy my real needs.
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.
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
Being a first time customer I was extremely impressed with how punctual and professional the technicians are. I highly recommend Paradise Heating and Air
They scheduled me in a timely manner. The technician (Jonathan)was very professional, explained the system, and answered all my questions.
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!
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!!!
Did a very thorough job of servicing my system. Will use 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.
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
Thank you Paradise Heating and Air for your quick response, great customer service and fair price!
Fast on time & courteous
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.
Very prompt, respectful, thorough, and didn’t break the bank.
Always knowledgeable, respectful, and right on time!
Great, fast and professional service always!!
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.
Awesome customer service. Exceeded my expectations compared to past experiences with different companies
Extremely nice, on time, helpful and explanatory. Very professional. Thank you
Awesome Work! Great Experience with Jonathan and Paradise Heating and Cooling Great experience from Jonathan and Christian! Job: Disassemble and remove old attic ductwork and install new ductwork and runs. Install Accuclean air filter in both attic and main floor systems. Install new smart thermostat and attic insulation infill. 1. Honest assessment of what is needed and more importantly, what is not needed. And not just trying to sell the most expensive option. 2. Competitive and reasonable quote. 3. I asked about radiant heat treatment as an add on, but he said while they could do it, it would not have efficient results and not worth the investment since I had a high hip roof and large attic area. 4. Great work ethic and work product. Duct system, filtering system and thermostat expertly installed, set up and running effectively. 5. All interactions cordial, efficient and polite. 6. Punctual in accordance with automated notices about arrival and appointment reminders 7. Clean work - brought coverings to reduce tracking of insulation through house areas traversed. Cleaned any evidence of insulation. 8. Works relatively quietly. No loud talk or music. 9. Small footprint on street. One van. I expected van and trailer. New materials brought in, unloaded and installed while old duct system all loaded up and removed. Very efficient. Overall, fantastic experience and is highly recommended.
Paradise answered my call late at night and made me an appointment for first thing in the morning and even showed up early. They crawled under my rental house through the dirt and mud to inform me that my landlord had me living in a dangerous environment. He was upfront and honest about everything and let me know the steps I needed to do to get my family out of this situation. No bandaid fixes from these guys, they do things in a professional manner and I couldn’t be more appreciative. Top notch customer service. Highly recommend!
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!!
Jonathan was very knowledgeable and friendly. Appreciated his candor and non-salesy guidance. We will be using them again.
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.
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!
Wonderful
Very professional and knowledgeable. No need to look over their shoulder. Very satisfied with their work.
Great service, assessed the issue in no time. Discussed all available options, extremely professional and friendly . Appreciated the help. Provided the best price .
We were very pleased with the service we received! The men were knowledgeable, honest, and timely. We would HIGHLY recommend this service!
Always on time and very well please explain everything that they did
Good service.
Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.
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!
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.
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!
Great service - always on time and very professional.
