Many folks just flip the switch to the air conditioner on when the weather starts getting warm. However, it is possible that the AC system suffered some damage over the winter that needs to be corrected before turning it on. It is a good idea to take a few minutes to check your a/c system before turning it on.
Step One: Visual Inspection
Start by taking a good look to see if there is any visible physical damage. If you happen to see some minor flattening of the aluminum fins that cover the coils do not be alarmed. This would not be classified as a big problem. However, if you see large sections of the fins flattened, this will prevent air from flowing over the fins thus diminishing performance. A professional should be called on to address the issue of flattened fins. Look for any plant or animal debris blocking moving parts. A twig could block the fan of a central air unit from turning. Be sure to inspect carefully. Spiders, wasps, bees and hornets may have taken up residence.
Inspect power cables for damage. Outdoor units may have damage caused by rotary trimmers. Indoor units may have a plug or cord damaged by furniture, pets or a vacuum cleaner. Don’t just fix a damaged cord or cable. Have it replaced. Air conditioning units use lots of power to run. A damaged cord or cable can overheat and cause a fire.
Step Two: Clean The Unit and Filters
Outdoor units can be cleaned with a garden hose and some detergent. Avoid using a pressure washer because the high pressure might actually break sensitive parts or inject water into sealed housings. Beware when using your hose to clean the fins as the fins bend very easily. Clean or replace the filter of the indoor unit before turning it on. If a musty odor is present, a light spray of Lysol brand disinfectant on the metal coils may help.
Step Three: Do A Sound Check
When your system is turned on for the first time after the winter, it should sound the same as it did last year. Any strange or unusual rattling or grinding sounds will be a sign of a potential problem. A slight whistle or squeak that rapidly dissipates, should not be a concern. If it continues and does not dissipate, the unit should be shut off and a professional should be called.

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!
