FAQs

What does HVAC stand for?
HVAC is the acronym for Heating, Ventilation and Air Conditioning. As HVAC specialists, we have the experience and knowledge to diagnose and repair your heating systems and air conditioning. You may need a HVAC contractor when upgrading your home, moving into a new home, or any time you are experiencing climate issues in your home.

When should I replace my heating, cooling and ventilation system?
You should consider the age, efficiency, performance and frequency of system usage. An indoor weather system that is more than 10 years old is likely driving your energy costs up and should be replaced. Does your system break down often? Replacing parts to an inefficient system is not likely going to solve your problem. Systems operating in extreme weather conditions will need to be replaced more often than one that is not operating as often.

When should I repair my heating, cooling and ventilation system?
If your equipment is in good condition, repairing it may be the right thing to do. Deciding whether to replace or repair is always a tough decision, but our team of experts will be happy to assist you in making that decision. You should have your equipment serviced at least once (but preferably twice) a year to be inspected, cleaned and adjusted. It will reduce risks and allow a team of professionals to repair a problem before it results in system failure.

How can I reduce energy costs in different seasons?
At Carolina Air Services of Raleigh we can help keep homeowners cool in the summer and warm in the winter. In the winter you want to reduce heated air from escaping to the outside. You can do this by keeping your garage closed, using clean filters and lowering your thermostat by a degree or two to save on your heating bills. In the summer, set your thermostat as high as comfortably possible. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. Remember not to place lamps or TV sets near your air conditioning thermostat. Ceiling fans and whole house fans help cool your home by circulating air more effectively. Plant trees or shrubs to shade air-conditioning unit and it will use less electricity. If you're ready to improve the efficiency in your home, contact us and ask about an energy audit program to identify areas where homes waste energy and money.

Should I trust the Yellow Pages in searching for HVAC repair?
The Yellow Pages will not help you in the selection process for a contractor. The Yellow Pages is outdated and static. There is limited information offered, which will not help you distinguish between the different contractors. A website is informative and interactive. Check out your options on the web!

Is there anything I can do before calling Carolina Air Services of Raleigh?
Make sure that circuit breakers are ON or that fuses have not blown. Check your home or office's airflow. Air filters should be clean and vents should be open and uncovered. Look at your thermostat to make sure the system is set on the appropriate settings.

What does SEER stand for and how does it relate to me?
SEER stands for Seasonal Energy Efficiency Ratio. Your SEER number measures the efficiency of air conditioners and heat pumps. The higher the number the greater your energy savings are. Manufacturers build systems with SEER ratings which need to have a 13.0 rating or higher. More HVAC terms and definitions are available here.

What does Energy Star mean?
The Environmental Protection Agency (EPA) has standards for heating and cooling products. The Energy Star marks high-efficiency and energy savings, and investing in such equipment can result in lower utility bills.

What is the average lifespan of heating and cooling equipment?
Most systems have a lifetime of 10-12 years, but we suggest you get your system inspected for efficiency and performance by a professional after 5 years. As your equipment gets older, its efficiency subsequently decreases and may need repairs more often. Preventative maintenance can prolong the life of the equipment.

How often should I clean my furnace?
It is highly recommended that you have your furnace cleaned and checked annually. It may need servicing more often if it is older. Carbon Monoxide can leak out of cracks that develop within a furnace over time. For your safety, it is important to have a professional eye maintain your furnace.

Should I have my ducts cleaned?
Yes. Dirty air ducts can make you sick, impact your utility bills, make your house dirtier and eventually cause system failure. Mold buildup, rodents, dust, debris and other particles can contaminate your ducts. Carolina Air Services of Raleigh suggests cleaning your ducts every 3-5 years. Schedule an appointment immediately if members of your household experience unusual symptoms that may be related to the environment within your home. Read Environmental Protection Agency's The Inside Story: A Guide to Indoor Air Quality for preventable tips for IAQ problems.

What is duct cleaning?
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers, heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.

What are the benefits of a humidifier?
A humidifier will reduce the discomfort people experience with dry air, such as itchy skin and a hard time breathing. Dry indoor air can also inflict damage on your furniture. A humidifier, when used properly, can reduce your energy bill.

Can I plant or garden around my outdoor unit?
Yes, actually shaded units use less electricity than the same ones operating in the sunlight. Make sure you plant the trees or shrubs far enough away so that they do not obstruct airflow.

How often should I change the filters in my home or building?
Replace the filters as often as instructed, but regularly inspect them. Most filters need to be changed every month. Dirty filters will limit the airflow and increase the cost of your utility bills.

Should I turn the air off when I am not home?
No, just turn the temperature up a few degrees to be closer to the outdoor temperature. The AC unit will not have to work as hard when you return as it would if you turned it completely off.

How do I know what size system I need?
There are important factors to be considered when determining the system size for your home. Our team will consider the local climate, humidity, shade, insulation, occupants, appliances, windows, and square feet to be cooled. A system that is too large for your home will cool or heat your house quickly, but maybe too quickly, which can result moisture/mold issues. A system that is too small will not be able to meet your needs, especially in extreme weather conditions.

How do I protect my home or building from Carbon Monoxide pollutants?
Because you cannot see or smell Carbon Monoxide, it is important to understand where it comes from and some of the symptoms. At low levels, the deadly gas can cause headaches, dizziness and fatigue. Most people find themselves more at risk in the winter months. Please be careful with space heaters, gas stoves, and fireplaces. We also recommend you allow plenty of air flow in rooms where these items are used. Ask us about getting carbon monoxide detectors installed in your home.

How do I know if my home or building has poor air quality?
Are you often uncomfortable with the indoor climate? Identifying what it is about your current system that makes you uncomfortable will help you resolve it with our specialists. For example, let us know if the air in your home is too cold, overly hot, overly humid, has lingering odors or you suffer from indoor allergies.

What equipment requires preventative maintenance?
All of it! At least once a year heat pumps and air conditioners require inspection by a professional. We recommend scheduling at least one tune-up on your equipment every year. We recommend getting boilers, chimneys, ductwork, dampers, the gas meter, furnaces, pipes, pumps, the oil tank, radiators and valves inspected. The compressor, coils, fan and refrigerant lines require inspection as well. Contact us if you have questions on a particular part of your HVAC unit and important preventative maintenance.

What are the symptoms of an unhealthy home or building?
  • Eye, nose and throat irritation
  • Sinusitis, Sinus Infection, Bronchitis and long-lasting Headaches
  • Fatigue, Irritability
  • Reduced Concentration
  • Asthma
  • Dry Skin

-Barbara Rudnick

I contacted Blake yesterday since my AC was not working properly. We texted and he let me know I needed to turn it off so as to not cause any damage to the system. Blake worked me into his day. When he arrived, he repaired my HVAC system in less than an hour. As always, he was professional and explained everything that he did and showed me the little part that had worn out. I appreciate his assistance! I would rate Blake as 10 out of 10!!


-Kathy Gogarty-Gajan

Derek and Blake did fantastic in finding the minute leak on the copper joint on my 2nd floor HVAC. I know by discussion with Derek that he would have replaced the outdoor HVAC unit if they could not find the leak at no cost to me. That is highest form of trust, truth in advertising and honoring the warranty. I also told Derek that my June electric bill had a very large drop in cost due to the two new HVACs compared to the May bill. Thanks for all!


-Dave and Valerie Shunk

We have been clients of Carolina Air since 2018 and have found them to be prompt, knowledgeable & professional with each visit - especially our technician Blake. He is always willing to share his knowledge & expertise with us to help us better care for our unit. We would highly recommend them to anyone looking a good, reputable company to service their heating & cooling units. Best regards,


-Bob & Kathie Laufhutte

I am appreciative of prompt, reliable and thorough service with a very personal touch. Blake was patient did not appear rushed during his visit with us. I also greatly appreciated the flexibility I have been offered in scheduling future service. With other companies, I felt I was being taken advantage of but certainly do not have that sense with Carolina Air.


-Bob Doud

I thought I had a thermostat problem but Blake quickly analyzed what I had observed on the thermostat and went to check the HAVAC outside. In approximately two minutes he found the problem: a contactor had burnt out. My thanks to Blake House and Carolina Air!
Update: I called in Thursday morning (21 Dec) and asked if Blake House could stop by Friday because the thermostat was not working correctly. Blake texted me during the day (Thursday) and said he would stop by after his last call! Blake stopped by at 6 PM Thursday night and installed a new thermostat. The HAVAC is now providing amazing heat! My thanks to all!


-Dave Shunk

Blake was the tech that came out to our home and he was nothing short of a courteous professional- exactly what you would want from this type of service. He listened carefully to each of our concerns and answered all of our questions. He also went above and beyond to address the issues we had. I couldn't recommend this company and Blake more.


-Kyle Clifton

We finally found a great HVAC company we can trust. Blake came out on a Saturday and was so detailed. He explained the exact problem and how to fix it. He was very professional and courteous. We will be purchasing a maintenance plan to ensure our system is functioning at it's best ability. Thanks Ryan for reaching out and sending Blake out. He was the BEST!


-Melody B.

My wife and I are extremely happy with Carolina Air Services. Tracy and his team have been providing semi annual service for us as well as emergency repair services for many years. We recently had them replace two 20 year old HVAC systems with modern, updated equipment. This installation was not a simple replacement. It involved relocating both the indoor furnaces and outdoor units to accomplish some other goals that we have. All of Carolina Air Services team members were polite, respectful and most importantly knowledgeable. The job was completed quickly with no interruption in heat or cooling. We give them our highest recommendation!


-Gary K.

Tracy and his team are an excellent team to do business with. They treat you with awesome respect and kindness. They are very patient with you while answering your questions and addressing your concerns. They will do their best to fix the issue at the best rate possible. They guarantee their work.


-Lisa L.

We required service to our furnace during the extreme cold this past winter and as it turned out a replacement of our unit. Tracey and his team were able to perform the replacement in 24 hours, doing an excellent job and upgrading us to a newer more efficient product. I would recommend them for their knowledge, work ethic and excellent customer service.


-Judy K.

I have called Tracy 3-4 times over the last couple years when my AC wasn't working properly and he has always respoded quickly. He and his team are always polite and do a good job! They are honest! It is so nice to work with people that I can say this about. Thank you Tracy and guys for helping me again!


-Cheryl V.

Yesterday I was melting! Today I'm cold! Thanks to Tracy Wood and Carolina Air Services! I will only use Tracy and his awesome team for any and all of my heating and cooling needs! Hands down--the nicest, fastest, most reliable, reasonably priced, and trustworthy service in the Triangle! Thank you!


-Dutchess M.

The installation works as advertised. Nice to get something done that doesn't need a call back or two. Great job.


-Lowell Bonnett

Tracy and his team were the best. They came quickly within an hour on a hot Saturday. They fixed my air conditioning problem quickly and were professional and pleasant the whole time. It was one of the best service calls I have ever had. Thanks


-Warren Briggs

Called Tracy on a Sunday morning at 10am and he was at my house at 1015am. He had the A/C fixed within 20 minutes. Very professional and punctual. I will recommend you and your company to everyone that I can. Thanks again.


-Bradley Macey

Tracy and his team provide fast and quality service at a fair price. We had our AC break down on July 4 th and were pleasantly surprised that they were able to come out to repair our AC on a holiday. Tracy returns calls promptly and shows up when he says he is going to. I have used him twice now and been very satisfied both times.
