Float Switch

« Back to Glossary Index

A float switch is a safety device used in HVAC systems, usually installed in the drain pan of an air conditioning or heat pump system. Its purpose is to detect when the water level in the drain pan rises too high, which could indicate a clog or other drainage problem. If the water reaches a certain level, the float switch triggers a mechanism to shut off the system, preventing water overflow and potential damage to the surrounding area.

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.

If you are having any HVAC issues please do not hesitate to call Paradise Heating and Air. Mr. Jonathan and his team were quick and provided answers to all my questions. I appreciate how quick they came out and fixed my issue being that we have had some extremely hot temperatures lately. I look forward to working with them in the future. I will be recommending them to anyone who has an issue. Thanks again to Paradise Heating and Air.

I called at the end of the workday on Friday when we arrived back home from a trip and the temp in our house was 114! We had, fast, fair service and were cooling off within the hour I had called. Excellent experience!

Jonathan and his helper were awesome. Keeping us informed as to what they were doing as they replaced our heating and air units. They were pleasant to have around and did a great job. They not only left the areas clean they hauled off all the old equipment. We would highly recommended them to everyone.

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.

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.

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!

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 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!

Paradise has become our go-to HVAC company. We have used them for several smaller repairs and they always provides a reasonable price and didn’t try to upsell replacing our 30 year old unit before we were ready. Then, when we were finally ready to replace our unit we got quotes from Paradise and several other companies. Paradise was by far the best value not only in terms of price but also unit brand and warranty. We even ran all of the quotes through AI and his came in 1st in terms of value, price and ROI! Great company overall - can always trust them to provide great, high quality work and reasonable prices.

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.

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!

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

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

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.

We recently bought a home and right away one of the AC units failed. Of course it was after hours (do AC units ever fail not after hours?). I called Paradise Heating and Air and they dispatched quickly, diagnosed the problem, and had us cool and running again before the kids were even in bed. Jonathan figured out the issue fast, and the quality of work and the cleanup afterward were truly noticeable. They've become our go-to HVAC company, always a notch above on service and workmanship. If you need emergency AC repair or any HVAC work in Vestavia Hills or anywhere in the Birmingham area, don't hesitate to reach out to this team. Love working with them!
