A heat exchanger is a device in an HVAC system that transfers heat between two substances, such as air and a heating element or fluid, without the substances mixing. In a furnace, the heat exchanger warms the air by transferring heat from the combustion gases to the indoor air before circulating it throughout your home. This ensures efficient heating while keeping harmful combustion gases separate from the indoor air.
just left us a 5 star review
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 did a great job. Highly recommended.
Replaced a furnace vent pipe and roof cap, Jonathan and Matt were competent technicians and explained everything to me clearly and the quote and the final price were the same. comparing quotes, they were very competitive and provided a high degree of professionalism on the job. Thank you very much.!
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.
Paradise ALWAYS delivers high quality service! I love the honesty and integrity of this company. Paradise is without a doubt my first choice for all my heating and air needs!
Excellent service, very kind, and very reasonably priced. Went the extra mile to help me out. Really appreciate you guys!
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
Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough
Jon and his team have renewed my faith in the HVAC industry. They service two homes with aging Heating & Cooling systems, and they've gone above & beyond in both cases. From surveying the attics for proper insulation, to accessing the basements and crawl space for any issues that might need to be addressed, I'm confident I'm in good hands with Paradise Heating & Air.
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!
Very professional, courtesy and helpful. We needed a part but no pressure to buy it. We will use them again.
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.
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.
Has spring service. Right on time, got it in good shape. Professional. Highly recommend!
Great service - always on time and very professional.
Jonathon and Christian did an excellent job! We would recommend them highly!
Exactly what I needed!
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.
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.
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.
We were very pleased with the service we received! The men were knowledgeable, honest, and timely. We would HIGHLY recommend this service!
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!
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!
It was a fluke I got them. I called to order a part, instead I got the best service of any HVAC service in the Birmingham area. Fast response, honest, efficient, and fairly priced. Professionals who care about their reputation. Thank you.
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!
5 stars! Look nowhere else for all of heating and cooling needs. Jonathan is amazing - experienced, reasonable and reliable. Look nowhere else!
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."
Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.
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.
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.
Paradise Heating & Air are always on time, friendly, & do a professional job.
Our AC was struggling a bit. Had another HVCA company come check it out first. Their recommendation was a whole new replacement unit. Bare minimum a $6000 repair job. Got a second opinion from Jonathan’s company, Paradise. All the unit needed was refrigerant. Saved us thousands !! We would recommend Paradise every day of the week and twice on Sunday.
Johnathan and Matt very knowledgeable and professional. Addressed my problem and fixed at a very reasonable price. Would highly recommend.
Excellent experience!
Thank you Paradise Heating and Air for your quick response, great customer service and fair price!
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.
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!
I have been extremely pleased with the work performed and customer service.
Great, fast and professional service always!!
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.
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.
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.
I’ve used them several times now and they are always quick to respond, very polite and honest. I would highly recommend them.
I had to leave another review for this company because we continue to be very impressed. Jonathan is an absolute pleasure to work with.
Always knowledgeable, respectful, and right on time!
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!
Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.
Always on time, easy to communicate, finest quality of workmanship and character, affordable pricing. Highly recommended.
