Thermocouple

« Back to Glossary Index

A thermocouple is a sensor made of two dissimilar metal wires joined at one end, which generates a small voltage when there is a temperature difference between the joined end (called the “hot junction”) and the other ends (called the “cold junction” or reference junction). This voltage increases as the temperature difference grows, allowing the device to measure temperature. Thermocouples are commonly used in HVAC systems to monitor and control temperature, especially in gas-powered equipment like furnaces and water heaters.

john DiOrio

Jonathan and the Paradise team are the best. In my 50 yrs of home ownership, I haven't had anyone I've trusted more. My wife and I downsized recently, and Jonathan helped us upgrade old to new heating & air units, including thermostats and attic insulation. Paradise Heating & Air is a great company... glad we found them years ago.

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!

Melanie Authement

Rory Chrane

Update: May 2026 Paradise came and serviced my business and home this week per the service agreement I asked them to sign me up for. Excellent trustworthy people and processes yields a top level result. You can trust them too. Call them and see what I mean. 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.

Kelly Rowe

Explained options in detail in a way that I easily understood. No pressure to do unnecessary work. Very nice and professional team.

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!!

Misty Hughes

I had my new unit installed about a week ago. Johnathan was the best. It was effortless , perfect workmanship , on time. Explained everything! Thank you Paradise !! FIRST RATE. TOOK CARE OF ME ASAP. WILL USE IN FUTURE FOR NEW UNIT

Hector Orozco

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!

David Brainerd

Jonathan did a great job. Highly recommended.

Ralph Ozley

Jon showed up as planned and committed to. A big plus was that he had the components on his truck to fix the broken part. Had my heat running after a 1 hour service call. Yes, I would recommend Paradise Heating and Air ...5 Star rec.

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!

Amanda Horsley

I had to leave another review for this company because we continue to be very impressed. Jonathan is an absolute pleasure to work with.

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.

Bryan Sutton

J. Chapman

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.

Zac Goozee

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.
