Common HVAC FAQs

Your home’s HVAC unit is a complex system built to weather mother nature’s many elements and keep you and your loved ones in the comfort zone 24/7. At Carolina Comfort Air, we know there are many questions you have as homeowners about your heating and cooling needs. We’re here to answer the most frequently asked HVAC questions. 

  1. How often should I service my HVAC system? 

Servicing your HVAC system can reveal leaks, rust or wear and tear, so scheduling regular preventive maintenance is the best way to ensure peak performance year round. It is recommended for homeowners to have their heating and cooling systems serviced 2X a year, bothin the spring and fall. Schedule your preventive maintenance with us! 

  1. What type of air filters should I use and how often should I replace them?

For optimal efficiency and filtration, we recommend that you replace your disposable filters at least once a month. Standard filters work to keep your system and its ductwork clean, but they can only do so much to improve indoor air quality. A media air cleaner does a much better job of trapping small particles. It rests between the main return duct and the blower cabinet and will improve dust and particle removal up to 7X more effectively than a standard filter. 

Upgrading to a pleated media filter will remove everything from dust to airborne viruses from the filtered air! 

  1. When should I replace my home’s heating and cooling system?

Understanding the tell-tale signs that your HVAC system has reached the end of its life and may soon need replacement is vital as a homeowner. The sooner you acknowledge these warning signs, the more time you have to budget and explore the best financing options. Frequent repairs, the use of R-22 refrigerant, and well aged equipment are among many indicators that your HVAC system may need to be replaced soon.

  1. What size HVAC system do I need? 

To ensure your new AC system is the right fit for your home and comfort needs, Carolina Comfort Air performs a detailed load calculation to determine the capacity of the equipment needed, as well as the distribution of air for each room. During your free in-home consultation, our consultants will ask a series of questions to further understand your current comfort issues. Do you have hot or cold spots in your home? High humidity? Our approach to professionalism is valuing our customers as partners. 

  1. Is a bigger HVAC system better?

Size does matter when it comes to choosing an HVAC system for your home, and bigger doesn’t always mean better. Right-sizing your system is all about choosing an HVAC system that is properly sized for your home after taking into account the size and configuration of your house, window locations, insulation levels of its thermal envelope, climate, number of occupants, and several other factors. Special calculations need to be conducted to determine which size system would best meet the heating and cooling needs of your home.

  1. What are the advantages of a programmable thermostat?

Programmable thermostats are more accurate and efficient than thermostats that contain mercury. A properly programmed thermostat can save up to 20% on energy costs! With a programmable thermostat, you can program settings in advance so that you can control the temperature at different times of the day. 

You will never have to worry about remembering to adjust the settings manually. By scheduling your programmable thermostat to a higher or lower temperature based on your weekday work hours, you can save money on energy bills without sacrificing comfort. A Carolina Comfort Air technician will gladly walk you through how to use your programmable thermostat.

Not only do programmable thermostats save homeowners money, but they also allow you to easily manage your indoor home temperature with smart controls. Remotely raise and lower temperatures using your smartphone, receive system diagnostics, and stay up to date with maintenance alerts.
