A single-stage furnace design that operates exclusively at its maximum capacity, meaning it always runs at 100% output whenever it’s on. Unlike modulating or two-stage furnaces, which can adjust their heating levels based on the home’s needs, a high fire only furnace does not have variable capacity and is either fully on or completely off. This can result in less energy efficiency and less consistent indoor temperatures.

just left us a 5 star review
Great service, price, and quality workmanship! Highly recommend! I will use them again.
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!!!
Fast on time & courteous
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.
5 stars! Look nowhere else for all of heating and cooling needs. Jonathan is amazing - experienced, reasonable and reliable. Look nowhere else!
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.
Thank you Paradise Heating and Air for your quick response, great customer service and fair price!
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!
I would definitely recommend this company they were very knowledgeable and a decent price!
Always on time and very well please explain everything that they did
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!
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!
We were very pleased with the service we received! The men were knowledgeable, honest, and timely. We would HIGHLY recommend this service!
Paradise was very responsive and was able to come same day. Very professional, nice and honest - would recommend to anyone!
Always polite. They were at my house at 8:30 pm making sure we had cool air.
Great prompt service fair price. Thanks..
Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!
Amazing service and very helpful as well as willing to inform me of what was going on.
Paradise Heating & Air was conscientious about scheduling and doing a thorough job in installation and servicing.
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!
Being a first time customer I was extremely impressed with how punctual and professional the technicians are. I highly recommend Paradise Heating and Air
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!
Came out same day and explained the problem I was having and how best to fix it, and also what to look for to get ahead of any future issues before they get too bad
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!
Extremely nice, on time, helpful and explanatory. Very professional. Thank you
Jonathan to the rescue! A quick response saved us from a miserable night. Jonathan had us fixed in a matter of minutes! Highly recommend!
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.
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.
I was fortunately able to get an appointment for the next day. Jonathan & Austin were prompt and kept me advised of their arrival. They quickly found the problem with my "heat" and were able to fix it without problems. They were very friendly and professional, and I felt that their pricing was fair and reasonable. Thanks again, Guys! UPDATE: I once again had a very good visit from Paradise Heating & Air - they are very prompt and reliable and do an efficient job - thanks once again! I definitely recommend these nice guys!!!
They scheduled me in a timely manner. The technician (Jonathan)was very professional, explained the system, and answered all my questions.
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!
Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.
Quick service, fair price, and very thorough with explaining different options. Jonathan was straight and to the point without any sort of pushy sales talk which is rare in the HVAC industry today. Highly recommend!
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 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.
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.
I’ve used them several times now and they are always quick to respond, very polite and honest. I would 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.
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.
Great, fast and professional service always!!
Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.
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.
Wonderful
I can not say enough great things about Jonathon and Paradise Heating and Air. From the moment they answered the phone I knew I made the right choice. This team is top notch! I called on Monday for attic insulation, Tuesday Jonathon came out and spent time showing me what I needed and Thursday the job is done! Clean, professional and treated me and my home like family. I will be using them for EVERYTHING they specialize in. You CAN NOT GO WRONG with this company! 1000% satisfied and never have been so happy to spend money on insulation 🥰.
I would highly recommend Jonathan and Paradise Heating and Air. I called multiple places to get quotes on replacing my two older units. What sets Paradise apart is Jonathan took the time to explain my current system, as well as pricing comparable new systems. Not once did he try and sale me the bells and whistles that did not align with what I was replacing like the other businesses. He was not pushy and his prices can't be beat. You can't go wrong with Paradise Heating and Air and they will be my shop for any HVAC needs moving forward. Thank You for being fair and honest.
