The setpoint is the desired target value for a specific parameter, such as temperature or pressure, in an HVAC system. It is the value that a thermostat or controller aims to maintain by adjusting system operations. For example, if you set your thermostat to 72°F, that temperature becomes the setpoint, and the HVAC system will work to keep the indoor temperature around that value.

Thank you Paradise Heating and Air for your quick response, great customer service and fair price!
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 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
Always on time and very well please explain everything that they did
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 Heating and Air are the BEST in the area! They’re very responsive and adapted quickly to our needs. Highly Recommend!!
Very professional and knowledgeable. No need to look over their shoulder. Very satisfied with their work.
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!
They scheduled me in a timely manner. The technician (Jonathan)was very professional, explained the system, and answered all my questions.
The only company I'll use for HVAC. Jon and his team explain everything, do meticulous work, and clean up after the job is done. What more could you ask for? Thanks guys!
On time, knowledgeable and friendly.
Response was immediate and was able to fix the issue the next day! Very friendly and great customer service and communication. The cost was very reasonable.
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!!
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!
Amazing service and very helpful as well as willing to inform me of what was going on.
Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.
I had to leave another review for this company because we continue to be very impressed. Jonathan is an absolute pleasure to work with.
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
Great service with very neat job. Highly recommend.
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.
Jonathan to the rescue! A quick response saved us from a miserable night. Jonathan had us fixed in a matter of minutes! Highly recommend!
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.
Great service, assessed the issue in no time. Discussed all available options, extremely professional and friendly . Appreciated the help. Provided the best price .
Did a very thorough job of servicing my system. Will use again.
Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!
Johnathan was great! We had a moisture problem in our kitchen cabinets that were on an interior wall. He spent a good amount of time figuring out what was going on, gave us a solution and answered all of our questions. A very good experience!
Fast on time & courteous
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!!
Always on time, easy to communicate, finest quality of workmanship and character, affordable pricing. Highly recommended.
I called at the end of the workday on Friday when we arrived back home from a trip and the temp in our house was 114! We had, fast, fair service and were cooling off within the hour I had called. Excellent experience!
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 polite, prompt and reliable. Will make sure you’re happy with their service
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.
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.
Great service - always on time and very professional.
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!
Jonathan did a great job. Highly recommended.
Johnathan and Matt very knowledgeable and professional. Addressed my problem and fixed at a very reasonable price. Would highly recommend.
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.
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.
Wonderful
I’ve used them several times now and they are always quick to respond, very polite and honest. I would highly recommend them.
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!
Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough
Jonathan and the guys did a fast and efficient job fixing our ac. Always a worry when it goes out at the start of summer in Alabama. I highly recommend paradise heating and air to fix your ac problem. Communicated arrival time, explained the issue thoroughly, also didn't break the bank! Thanks again paradise!
They did a great job installing my new unit
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.
