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.

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."

I’ve used them several times now and they are always quick to respond, very polite and honest. I would highly recommend them.

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.

Mark Hamblen

Did a very thorough job of servicing my system. Will use again.

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.

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.

Peter Wald

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

Cassandra Moore

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

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.

A Borden

Jason Motley

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.

Jerry Smith

On time. Made excellent recommendations. Work performed quickly and reasonably.

Kyndall Alexander

I would definitely recommend this company they were very knowledgeable and a decent price!

Wilson Moores

I have been extremely pleased with the work performed and customer service.

Steve

Always polite. They were at my house at 8:30 pm making sure we had cool air.

Charles Reynolds

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

Karen

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!

Blake Driskill

Excellent experience!

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.

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.

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!!!

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!

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

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.

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!

Katherine Marshall

Extremely nice, on time, helpful and explanatory. Very professional. Thank you

Cheryl Kruse

I highly recommend Paradise Heating and Air. I contacted them to give me an estimate on adding more insulation to my attic. They were super responsive. They came out, gave me an estimate that I felt was very reasonable. In a very short time I was on their schedule. They showed up at the time they told me they would and they did a great job!! They even took care of the areas that were leaking heat. They are very personable, great to deal with. I am super pleased.
