Indoor Coil

« Back to Glossary Index

The indoor coil, also known as the evaporator coil, is an essential part of an air conditioning or heat pump system. It works by absorbing heat from the indoor air to cool your home. Inside the coil, cold refrigerant flows and absorbs heat from the air that passes over it. Once the heat is removed, the now-cooled air is circulated back into your living space. The indoor coil is usually housed within the air handler unit or positioned above the furnace in central HVAC systems.

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!

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.

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."

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.

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!!!

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!

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!

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.

I can not say enough amazing things about my experience with Paradise - most importantly, about JONATHAN PERKINSON! He is super knowledgeable about any and all HVAC systems, and he answered all my questions - he actually went above and beyond my expectations. I am excited about this company bc I have tried SEVERAL in the Birmingham area - and I’m telling you - this is the company to use and Jonathan is the one specifically that I will be calling again and 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.

Trustworthy and honest! I'm so thankful for the service I receive from Paradise Heating and Air. I am a repeat customer because I know Jonathan will not try to sell something I do not need. He explains any issues in detail leaving the decision up to me on whether or not to replace a part. Jonathan takes his time to make sure everything is in good working order before he leaves.He truly cares about his customers. I highly recommend keeping your unit(s) serviced twice a year. I am seeing the benefits on being proactive with this. It's totally worth it. I cannot rave enough about the customer service you receive from Paradise Heating and Air. Call them!!!

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!!

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.
