How Does My Furnace Work?

Arianne Large - Sunday, October 14, 2018
Without a doubt, cooler temperatures are arriving.  It won't be long until we all switch our HVAC systems to heat mode.  Have you ever wondered how your furnace works?

A gas furnace can be fueled by propane, oil, or natural gas.  When you set your thermostat to heat, the furnace's ignitor will fire up the burners.  The burners produce heat that moves into the heat exchanger.  The blower then moves the heated air through your ductwork and into the rooms of your home.

If you have an electric furnace, electricity powers heating elements which heats the air.  The heated air travels through the electric resistance coils and blower circulates the it throughout your home. 

No matter your heat source, your system will continue to run until the desired temperature set on your thermostat is satisfied.

Until we get back to our warm Carolina weather, furnace maintenance is essential.  Our Technicians will deliver the TLC that your furnace needs to reduce wear and tear to components, maintain the highest efficiency possible, catch issues before they progress into costly repairs, and ensure that all safety features are working properly. 

We hope you do not have issues with your furnace.  If you do find yourself without heat, call Helms Heating & Air Conditioning at 704-821-6255.  Our Technicians are trained to diagnose and repair all brands of furnaces.  We are available seven days a week, 24 hours per day, should your family have a heating emergency.

Beware This Expensive A/C Scam!

Arianne Large - Thursday, September 20, 2018
Have you ever heard an HVAC Tech say they’re going to “gas up your A/C” or “top it off with Freon”? Most homeowners know that refrigerant, Freon (R22) or Puron (R410A), plays a vital role in cooling their homes. So when a Tech says they’re low on refrigerant - they pull out their wallets way to easily. 
How often should your air conditioner need to be refilled with refrigerant? 


Your air conditioner does not “use” refrigerant like a car uses gas. The refrigerant flows through a sealed loop of copper throughout the system. So, you should never have to add refrigerant - unless there is a leak. If a leak is not repaired, you will eventually find yourself in the same uncomfortable and expensive situation.
If refrigerant is added to your air conditioner, the Tech should take the time to explain that there is a leak in the system and discuss your options:

Option 1: Recharging your air conditioner without locating/repairing the leak. Since locating and repairing a leak can be an expensive, we may not suggest the leak search in certain situations. If you are a new customer and we have no history of adding refrigerant, we can assume that it may not have been charged properly by a previous service provider. If you have plans to replace unit before the next cooling season, we wouldn’t recommend investing more money into the old equipment.

Option 2: Locate and repair the leak. A Technician may use an electronic detector, a bubbling agent, or other methods to determine the source of the leak. Once it is found, they will need to repair or replace the leaking component. Once completed, refrigerant will be added back to the system and tested for correct operation.

Beware of an HVAC Technician that says you need new refrigerant on a regular basis or on a free routine maintenance visit when your system has been running and cooling properly. You may also want to reconsider your choice of contractor if they are quick to charge your system without discussing the possible leak.

3 Tips about HVAC That Your Realtor Doesn’t Tell You

Read this if you’re in the market for a new house with the hopes of energy efficiency.

Is increased energy efficiency on your wish list for your next house? There are a lot of things your realtor can help you with, but energy efficiency and your HVAC system aren’t on that list. Here are three tips about HVAC your realtor might not tell you that you need to know before purchasing a new home:

Tip #1: Don’t Trust the Inspector Alone

The majority of home buyers will have an inspection done before closing on a property. This is great, but you should also consider having your own HVAC tech examine the unit before you sign on the dotted line. Your tech can spot even small problems and give you an idea of what it will take to fix them. This step can help ensure you aren’t stuck with an energy-sucking HVAC system.

Tip #2: Know the Age of the Unit

No matter how well a system is running, its age will have an impact on its performance, specifically on its energy efficiency. Most HVAC units will start to decline at about 15 years of age, even if they seem to be still functioning properly. Advances in heating and cooling technology mean a new unit will save you significantly over time and make your home more energy efficient.

Don't play a guessing game with your new home's HVAC system. Ensure energy efficiency by calling in the experts at Helms Heating and Air Conditioning.


3 Ways to Say Goodbye to Airborne Pollutants This Summer

Improving your indoor air quality can be as easy as 1-2-3.

Summer is the height of allergy season, and with it comes compromised indoor air quality. What can you do when you’re still sneezing after you get inside? Take a look at three ways to say goodbye to those pesky airborne pollutants this summer:

#1: Don’t Neglect Your Air Filter

Your air filter is the doorway to your air conditioning system. What goes in can also come out if your filter is dirty. Changing the air filter is the easiest way to help keep your indoor air clean. The filter traps pollutants, including allergens, and prevents them from getting pulled into your HVAC. Not only does this help protect the cooling system from those pollutants, but it also keeps those pollutants from recirculating throughout your home.

#2: Invest in Air Filtration

A good air filtration system will trap up to 98% of airborne pollutants and keep them from blowing around in your house and irritating your sinuses, eyes, skin, and respiratory system. Some of the things that could be floating around your home without you even knowing include mold, bacteria, pet dander, pollen, smoke, and household chemicals. Getting rid of these with a filtration system can help you breathe easier and feel better.

#3: Humidity Control

Air that is very humid is going to hold onto pollution more readily than air that is less humid. A dehumidifier in the summer can keep your indoor relative humidity in check and help reduce the pollutant levels.

No one wants to breathe polluted air, especially in your own home. To say goodbye to airborne pollutants and improve your indoor air quality, reach out to the pros at Helms Heating and Air Conditioning today.
