Check Valve

« Back to Glossary Index

A check valve is a device used in HVAC systems that allows fluids, like air, water, or refrigerant, to flow in only one direction and prevents them from flowing backward. It works automatically, using internal parts like a disc or ball that move to either block or allow flow, depending on the pressure in the system. These valves help protect equipment and maintain proper operation by making sure fluids always move the right way.

Trustworthy and honest! I'm so thankful for the service I receive from Paradise Heating and Air. I am a repeat customer because I know Jonathan will not try to sell something I do not need. He explains any issues in detail leaving the decision up to me on whether or not to replace a part. Jonathan takes his time to make sure everything is in good working order before he leaves.He truly cares about his customers. I highly recommend keeping your unit(s) serviced twice a year. I am seeing the benefits on being proactive with this. It's totally worth it. I cannot rave enough about the customer service you receive from Paradise Heating and Air. Call them!!!

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.

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.

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 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!!!

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.

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.

I highly recommend paradise heating and air to fix your ac problem. Communicated arrival time, explained the issue thoroughly, also didn't break the bank! Thanks again paradise!

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

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!

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.

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.

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!

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 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 🥰.

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!

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.

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.

It was a fluke I got them. I called to order a part, instead I got the best service of any HVAC service in the Birmingham area. Fast response, honest, efficient, and fairly priced. Professionals who care about their reputation. Thank you.
