When most people think about cooling their home in Raleigh or Durham, they think about about air conditioning. They know that air conditioners blow cold air, and they think that this how they cool. The reality is a little more complex. Air conditioners don’t actually cool your house by blowing cold air. They cool by removing heat and humidity from the air – and that difference is important.
An air conditioner extracts the heat and humidity from the air inside your home and moves it outside. A heat pump does the same thing in the summer, but in the winter it can reverse this process, and extract heat from the outside air and move it inside your home. Air conditioners and heat pumps require an indoor coil to transfer heat, as well as a fan component to move the air it conditions. They can use an electric air handler (for electrically heated homes), or a gas or propane furnace.
For those who want more technical explanations, you can visit the EnergyQuest website or How Stuff Works for excellent video demonstrations. For those of you who don’t care HOW it works, only that it DOES, the important thing to remember is that these are both heat transfer devices, but a heat pump can heat as well as cool.
Because they are not creating heat (like a furnace), only moving it from one place to another, air conditioners and heat pumps are energy efficient. Advancements in the refrigerants and compressors over the past few years have made them even more economical. If your home already has an air conditioner, newer models can be 30% or more efficient than those manufactured just a few years ago.
Heat pumps tend to be most efficient when the outdoor temperature is over the freezing point. We’re fortunate that in North Carolina we have very few days of the year when temperatures dip below freezing – so heat pumps are a great option here. If you are interested in cooling your home, a heat pump can be a very attractive option.
Properly sized and installed duct work is critical for the proper operation of air conditioners and heat pumps. Remember – they rely on transferring heat from the air, so if airflow is inadequate they will not work properly. Heat pumps are especially sensitive to air flow, so there may be situations where air conditioners are a better option – unless duct renovations are being done. Your contractor should evaluate your duct work to ensure it is sized and installed properly.
For homes without central duct systems, ductless AC and heat pump units are a great option. And if you really want to maximize your energy efficiency, Geothermal heat pumps use the relatively stable temperatures found below ground to provide great indoor comfort year-round, along with exceptional energy savings.

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!
