DX stands for “Direct Expansion,” which refers to a type of HVAC system where the refrigerant absorbs heat directly from the indoor air and evaporates as part of the cooling process. In this system, the refrigerant circulates through coils and changes state (from liquid to gas) as it absorbs heat. This is a more efficient and compact design compared to systems that use secondary heat-transfer fluids, such as water, to transfer heat.

just left us a 5 star review
Jonathan and his helper were awesome. Keeping us informed as to what they were doing as they replaced our heating and air units. They were pleasant to have around and did a great job. They not only left the areas clean they hauled off all the old equipment. We would highly recommended them to everyone.
Great service, price, and quality workmanship! Highly recommend! I will use them again.
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.
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.
Always on time, easy to communicate, finest quality of workmanship and character, affordable pricing. Highly recommended.
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!
Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!
They scheduled me in a timely manner. The technician (Jonathan)was very professional, explained the system, and answered all my questions.
Paradise was very responsive and was able to come same day. Very professional, nice and honest - would recommend to anyone!
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.
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!
Wonderful
Jonathan to the rescue! A quick response saved us from a miserable night. Jonathan had us fixed in a matter of minutes! Highly recommend!
These guys got the job done! Came in did not try to sell me a unit but fixed my existing unit and I appreciate them so much bc it was the hottest day of the year and my unit was completely out. I recommend 💯
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!
Excellent service, very kind, and very reasonably priced. Went the extra mile to help me out. Really appreciate you guys!
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!
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!
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.
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!!
Awesome customer service. Exceeded my expectations compared to past experiences with different companies
Jonathon and Christian did an excellent job! We would recommend them highly!
Jonathon provides excellent service! Shows up on time, no mess, good at explaining the problem and does high quality work.
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.
Paradise Heating and Air are the BEST in the area! They’re very responsive and adapted quickly to our needs. Highly Recommend!!
Johnathan and Matt very knowledgeable and professional. Addressed my problem and fixed at a very reasonable price. Would 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!!
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.
Jonathon, as always, provided great service! He is very efficient and honest. Thanks Jonathon, Charles
Most honest, knowledgeable and affordable HAVC company I've ever dealt with.
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 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.
Thank you Paradise Heating and Air for your quick response, great customer service and fair price!
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.
Jonathan was very knowledgeable and friendly. Appreciated his candor and non-salesy guidance. We will be using them again.
Great service, assessed the issue in no time. Discussed all available options, extremely professional and friendly . Appreciated the help. Provided the best price .
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
Excellent service, on a Sunday, highly recommend :)
Did a very thorough job of servicing my system. Will use 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!
Professional, on time, fair prices, great job!
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.
Very prompt, respectful, thorough, and didn’t break the bank.
On time. Responsive. Seemed confident with expertise. Explained issues well. Serviced and repaired older ac system and did not try to sell me a new one. Kept everyone cool for Mothers Day.
Has spring service. Right on time, got it in good shape. Professional. Highly recommend!
Explained options in detail in a way that I easily understood. No pressure to do unnecessary work. Very nice and professional team.
Being a first time customer I was extremely impressed with how punctual and professional the technicians are. I highly recommend Paradise Heating and Air
