Crankcase heater

« Back to Glossary Index

A crankcase heater is an electric resistance heater installed on the compressor’s crankcase in an HVAC system. Its purpose is to prevent liquid refrigerant from mixing with the compressor oil by keeping the refrigerant in a vapor state. This helps protect the compressor from damage caused by refrigerant-oil dilution, especially during colder weather or when the system is not running. While some newer cooling systems may not need crankcase heaters, they are commonly required for heat pumps to ensure proper operation and longevity.

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!

Brian Motley

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.

Good service.

Mary Cavett

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.

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!!!

Pam Cain

Great, fast and professional service always!!

Melanie Kettle

Great service - always on time and very professional.

Steve S

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!

Cassandra Moore

Bryan Sutton

Laurie Dunn

Abby Beckloff

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!

Gayle Wroclawski

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!!

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

Jonathan was fantastic to work with!
