Heat gain

« Back to Glossary Index

Heat gain refers to the increase in temperature within a conditioned space due to various sources. These can include heat from sunlight entering through windows (solar radiation), warm air infiltrating through gaps or leaks, heat generated by people as they breathe and move around (occupant respiration), and heat emitted by lighting, appliances, or other devices inside the space. This concept is important in HVAC as it helps determine the cooling capacity needed to maintain a comfortable indoor temperature.

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.

Kyle & Joanna Baker

Jonathan was fantastic to work with! We had multiple quotes and opinions on some work we needed to get done and his recommendations and quote came in best and he had some recommendations others did not make that make us feel like he really cared about doing the right thing and really inspected our hvac situation. Jennifer and Gracie were also stellar! Will call them back and recommend to our friends!

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!

Charles Reynolds

Jonathon, as always, provided great service! He is very efficient and honest. Thanks Jonathon, Charles

Melanie Authement

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

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.

Good service.

Nancy Hollaway

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.

Andrea Martin

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

Carole Grimes

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.

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!

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."

Jessica VanLandingham

He was on time and got the insulation job done quickly. I had contracted with another company who no-showed twice, so being able to call Paradise and get it done within a short time was great.

Nichole Pompey

Johnathan and his son came out quickly and repaired my air conditioner. He explained very clearly what the issue was and temporarily fixed my air while we waited on the warranty part from the manufacturer. Service and hospitality was excellent!

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.

Dave Meyer

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.

Brian L

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

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.

Amazing service and very helpful as well as willing to inform me of what was going on.

SteelCityScreenPrint

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!

A.K. Powell

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

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

Paradise Heating and Air was great to work with—professional, on time, and very thorough.

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.
