Refrigerant charge

« Back to Glossary Index

The specific quantity of refrigerant that must be present in an HVAC system for it to operate efficiently and effectively. Maintaining the proper refrigerant charge is crucial because an undercharged or overcharged system can lead to problems such as reduced cooling or heating performance, increased energy consumption, and potential damage to system components. The correct refrigerant charge is determined by the system manufacturer and is typically measured by weight or pressure.

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.

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!

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

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.

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!!!

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!

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!!

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.
