Dry bulb thermometer

« Back to Glossary Index

A dry bulb thermometer is a device used to measure the air temperature without taking into account humidity or moisture levels. It simply measures the heat energy in the air and is a key tool in HVAC for assessing temperature conditions. It is called “dry bulb” because the thermometer’s bulb is not affected by wetting or evaporation.

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.

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 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.

Jonathan and his crew are always quick to respond and on time. They always help me to understand what is going on with our AC and heating units. I get a concise explanation of what needs to be done. I have always gotten an honest answer about my current units and I have never gotten any pressure to replace the equipment that did not need replacing. It feels great to be able to trust the information you get from the people looking after your HVAC equipment, and that is what we get from Paradise. T. Marvin

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!

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!!!

I can not say enough great things about Jonathon and Paradise Heating and Air. From the moment they answered the phone I knew I made the right choice. This team is top notch! I called on Monday for attic insulation, Tuesday Jonathon came out and spent time showing me what I needed and Thursday the job is done! Clean, professional and treated me and my home like family. I will be using them for EVERYTHING they specialize in. You CAN NOT GO WRONG with this company! 1000% satisfied and never have been so happy to spend money on insulation 🥰.

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!

I was fortunately able to get an appointment for the next day. Jonathan & Austin were prompt and kept me advised of their arrival. They quickly found the problem with my "heat" and were able to fix it without problems. They were very friendly and professional, and I felt that their pricing was fair and reasonable. Thanks again, Guys! UPDATE: I once again had a very good visit from Paradise Heating & Air - they are very prompt and reliable and do an efficient job - thanks once again! I definitely recommend these nice guys!!!

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!

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!

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.
