Relax! This question comes to us R & S Mechanical often from our Residential customers!
Have you noticed times in which your heat pump is producing steam or vapor clouds during the winter heating season? Not to worry; your outdoor heat pump uses what’s called a defrost logic board. That board typically goes into a defrost cycle when the defrost thermostat is closed and the required amount of time has been satisfied. This causes the outdoor fan to stop, reversing valve returns to the cooling position and your auxiliary heat kicks in to temper the air temperature inside your home during this defrost cycle. Once this cycle concludes the outdoor fan comes on again and the reversing valve returns to the heating position, in which you may notice a “swishing” sound. This is due to the coil in the outdoor unit heating up during the defrost period that is meant to melt any ice building up. As the fan draws moist cooler air over the hot coil, this will create the water vapor or cloud that you are noticing. The vapor will stop momentarily as the coil quickly cools as the heat pump returns to the heating mode.
So sit back and relax as this cycle is a normal process and as temps drop down into the 20’s you may notice it less often as colder air retains much less moisture.

Gary R Jeff designed a great Mitsubishi Mini Split for my new Music Room. Julio and Marlon did a great job on the initial pre-plumb, and Julio and Jake returned to finish the install. I did have one minor glitch, and Jeff sent Barry out to take care of that. Great equipme...
Lisa G Have had nothing but positive experience working with R&S. Brittany is the front end of the company and does a great job representing company. friendly, pleasant and helpful. Provides accurate information and follows up as she says.
Sean H. I had R and S come out to my house for the second time in the last couple of years to fix an issue with our heating system, and they were able to show up quickly and promptly and fix the issue the same day. The folks I have dealt with at R and S have all been very friendly and helpful in explaining the two issues with our heater thus far. We've had very good experiences and would definitely recommend to other homeowners.
Mancy M. I would recommend R & S Mechanical at any time for those who are looking for professionalism and ability to make a major job look like it's a minor one. I contacted R & S as one of 5 suppliers and service companies to install a new unit in my house. Even though price was a factor, but I was also looking to work with an organization that would be honest and caring. I did find such values with R & S. They were the only one out of the five who actually called to follow up on their offer and ensure that everything was well explained and clear. Absolutely great guys and they made sure to keep the place clean after they left. I definitely made the right choice.
Jennifer R. I have dealt with R&S since I moved to Raleigh four years ago and they have taken consistently good care of my HVAC units. They are prompt, professional, courteous and definitely pick up after themselves. They even call me to schedule regular maintenance that comes with my service contract instead of me having to remember. I can get an appointment very quickly if something breaks on me and they always arrive early. I'm overall very satisfied.
Gail S. I have always been pleased with their service. They are quick to respond, even on weekends. I would definitely recommend them.
Carol C. Our overall experience with R&S has been exceptional. We have been homeowners for over 30 years and have never had better service, concern and respect as we have received from R&S. Highly recommend.
Barb and Jerry Our AC system failed on a Friday afternoon at our Daughter's condo. Shortly after our call, Randy and Mike came to our condo, diagnosed the unit and loaned us portable cooling units over the weekend. They installed a new system and got us up and running the following Tuesday. Their prices and service were great! Very responsive, very straight forward, no hard sell unlike the big companies. Highly recommended - excellent service!
