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.

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.

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!

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.

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.

The experience was excellent I will be using them again and I highly recommend them.

Ken Little

Awesome Work! Great Experience with Jonathan and Paradise Heating and Cooling Great experience from Jonathan and Christian! Job: Disassemble and remove old attic ductwork and install new ductwork and runs. Install Accuclean air filter in both attic and main floor systems. Install new smart thermostat and attic insulation infill. 1. Honest assessment of what is needed and more importantly, what is not needed. And not just trying to sell the most expensive option. 2. Competitive and reasonable quote. 3. I asked about radiant heat treatment as an add on, but he said while they could do it, it would not have efficient results and not worth the investment since I had a high hip roof and large attic area. 4. Great work ethic and work product. Duct system, filtering system and thermostat expertly installed, set up and running effectively. 5. All interactions cordial, efficient and polite. 6. Punctual in accordance with automated notices about arrival and appointment reminders 7. Clean work - brought coverings to reduce tracking of insulation through house areas traversed. Cleaned any evidence of insulation. 8. Works relatively quietly. No loud talk or music. 9. Small footprint on street. One van. I expected van and trailer. New materials brought in, unloaded and installed while old duct system all loaded up and removed. Very efficient. Overall, fantastic experience and is highly recommended.

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!!!

Donna Butler

On time. Responsive. Seemed confident with expertise. Explained issues well. Serviced and repaired older ac system and did not try to sell me a new one. Kept everyone cool for Mothers Day.

2025 UPDATE: I needed Jonathan service on Friday, April 3rd. I called his office at 6:40. Jonathan arrived at my home by 2 o’clock that afternoon. Got my unit back up and running in less than an hour. The team at Paradise heating and cooling. Always provide exceptional, customer service and expertise. As long as Jonathan is in business, I will continue to do business with him. "I was so impressed with Mr. Jonathan from Paradise Heating & Air! They were incredibly respectful of my home, even wearing shoe covers. They were punctual and kept me informed every step of the way. Mr. Jonathan took the time to explain the issue clearly and simply, without any confusing technical terms. They offered several options and let me decide what was best for me and my budget. I really appreciated that they didn't try to oversell me on something I didn't need. It's clear that Mr. Jonathan is knowledgeable and truly cares about their customers. I highly recommend Mr. Jonathan and Paradise Heating & Air to anyone looking for reliable and honest HVAC service. It's refreshing to find a company you can trust."

Nancy Hollaway

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.

Chris Holland

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!

glophers hicks

Jonathan was very professional and knowledgeable, with a great personality. I will be doing business in the future with his company. I immediately signed up with the company’s annual service plan.
