Had what I thought was an issue with my furnace at MIDNIGHT and was in a panic trying to decipher what I thought was an error code. Called numerous places advertising 24/7 assistance and no one could/would help. Jonathan Perkinson with Paradise actually called me back, explained it all to me and kept me from shutting it all down on a cold night. So kind and helpful!!! Highly recommended!

Highly recommend Jonathan and Matthew. They were able to come same day when my air stopped blowing cool air none other than the first week of consistent upper 80s weather. They were on time and from the brief description I shared over the phone they knew right where to start. They had the part that needed to be replaced and I had cool air flowing in less than an hour! Thanks guys will use you again.

Melanie Authement

Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough

Chris Holland

Jonathan and the whole Paradise staff are professional, courteous, and fast. I had a system failure, and they were able to get to me quickly and diagnose the problem. Through Jonathan's research he discovered my system had a warrantied part needing replacement and saved me $1600. I would HIGHLY recommend Jonathan and the Paradise crew and will be using again!

Gayle Wroclawski

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!!

Christine Wilcox

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.

Pat Turner

If only all of our consumer needs were met like the service provided by the team at Paradise Heating and Air. From the very cordial and helpful Paradise employee who answered our after-hours, weekend phone call to the technical service provided by Jonathan and Matthew on Monday - we couldn’t be more pleased. We were informed every step of the way via text of all pertinent information including: scheduled appointment time, tech arrival time with the id’s of technicians who would be performing the work. Jonathan and Matthew arrived five minutes earlier than the one hour scheduled window (no no-shows here), did what they had to do and didn’t use weaponry to determine labor costs. In a land where customers have seemingly been disregarded and led to die, the folks of Paradise have obviously seen themselves and decided to do things a different and better way.

Adam Myers

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!!!

Linda Thompson

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.

Malachi Ray

Great honest and helpful people.

Cynthia Gillantine

Very professional, courtesy and helpful. We needed a part but no pressure to buy it. We will use them again.

Steve S

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!

Kofi Creme

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!

Routine service plus setting changes plus education plus rec's for the future. Spent much more time than normal to satisfy my real needs.

Cynthia Belyeu

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.

John DiOrio

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.

Quick response for broken AC. Found the problem quickly and was able to fix on the same visit. They also recommended some improvements based on another issue I was having. Overall great experience.

Marianne Herman

Exactly what I needed!

Cassandra Moore

Always on time and very well please explain everything that they did

Brian Motley

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.

Polly Norris

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.

Andrea Martin

5 stars! Look nowhere else for all of heating and cooling needs. Jonathan is amazing - experienced, reasonable and reliable. Look nowhere else!

akash ahmed

Good service.

Donna Butler

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.

Natalia Nagorneac

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.

Dana Gaudet

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 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.

Audray Jones

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

Sandy Farris

Brian L

Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!

Rory Chrane

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.
