These are the top complaints that we hear from customers calling us for HVAC assistance. Most of the phone calls we get are for scheduled maintenance, broken heating and air conditioning units, or systems not performing at the highest level. At the heart of all of these complaints, is comfort. People want to stay comfortable as the weather changes. We see many heating and air conditioning companies in Charlotte that focus on comfort.

We agree that comfort is important, but it is not all you should be worried about.heat pump vs ac installation cost Comfort is important, but isn’t the safety of your family more important? high efficiency air conditioner wall unitHere at Killingsworth, we are shocked that we do not hear more Heating & AC companies talking about the serious health issues that can be caused by your HVAC system.mini split ac heat systems These are much more serious issues than just staying warm or cool. Did you know that in North Carolina indoor air quality is twice as polluted as outdoor air quality? Homes are now built so tight, that it does not allow fresh air in. That means it is important that the air in your home, that you are breathing, is not contaminated.

The materials used and how your heating and air conditioning system is installed, can go a long way towards ensuring the safety of your family. Minor changes can be the difference in you breathing in clean air or breathing in fiberglass. Another huge health concern is a system leaking refrigerant. It is so common to hear heating and air conditioning companies tell you that you are a pound low on refrigerant, and they can fill it up for a modest price. Did you know that your system’s refrigerant is only supposed to be filled up twice in the lifetime of the unit? If you are doing it more than that, then your system is leaking, and you are breathing in dangerous chemicals. It is always great to hear that an HVAC repair is inexpensive, and you just need to fill up the refrigerant to get you back to comfortable temperatures in the house. How much is your family’s health worth? Your doctor bills may be much more expensive down the road. Make the right choice for your family when choosing a Charlotte Heating and Air Conditioning company.

Another huge threat to your health is mold. Think about your heating and cooling system and where it is in your home. Your system is in a cold or humid dark place and it produces 17 gallons of water every day. If you have a leaky system, it can potentially lead to a huge mold problem. This is just one more thing you will be breathing if your system is not installed, repaired or maintained by the right heating and air company. Killingsworth is the only HVAC company in Charlotte that is qualified to do mold remediation. The final issue that you need to be concerned about is the quality of work. Small issues can turn into very big issues. The wrong advice or sub par HVAC service and inspection could cost you thousands more dollars or impact the health of your family. These are not things to take lightly when deciding on the right heating and air conditioning company for you. A bad HVAC technician cannot only overlook issues, but even over cleaning, oiling or tightening items on your heating and air conditioning system can actually do more harm than good.

Spring is right around the corner. It is time to make sure your air conditioning is serviced. Don't wait until it is too late to properly maintain your heating & cooling systems.

How To Clean Your Condenser Coil Killingsworth Furnace Special - Fall 2015 Killingsworth January 2015 Furnace Tune Up Special Killingsworth Komfort Air: Heating and Cooling Heating & AC Testimonial Brian Holler was our Superman last night, disguised in a Killingsworth uniform. With 100 degree heat, an HVAC unit being out for days could have been deadly for our dogs in the house. He came out when he said he would, discussed the problem with us and was able to fix the issue, onsite, the first time. He went above and beyond to double check the evaporator just to make sure there wasn't a lingering issue to cause trouble in the near future. Definitely would recommend Killingsworth - first class service from the moment their dispatcher LaQuinta answered the phone through the time Brian emailed us our invoice for easy record-keeping.

THANK YOU for taking care of my family like it was your own.If there is a low-temperature difference across the evaporator coil in your air conditioning system, you might have a refrigerant flow problem. The heat-handling capabilities of your system may also be failing as well, as the low-temperature difference also indicates a capacity drop. It can be difficult to diagnose issues with such a complex system as your facilities central cooling and heating applications. However, if you take the time to notice the specific signs that certain parts of your HVAC unit are malfunctioning, it’s easier to fix them. Refrigerant problems are quite common. This week, we’ll walk you through how to diagnose refrigerant flow problems  so you can efficiently rectify the problem with the help of an informed HVAC maintenance team. Subcooling In The Condenser Subcooling is the difference between your system’s measured liquid temperature and the saturation level at a given pressure. To get the amount of liquid subcooling in the condenser, simply subtract the condenser outlet temperature from the saturation temperature.

If charged properly, a forced-air condenser will have 6-10 degrees of liquid subcooler. Condenser subcooling can be an indicator of your system’s refrigerant charge. The less the refrigerant charge, the less the subcooling. Making sure you actively check the amount of subcooling taking place in your condenser will help you diagnose whether or not you have a refrigerant flow problem within your HVAC system. Watch Out For Liquid Line Restriction A restricted liquid line will starve your evaporator of refrigerant. A notable sign that you have a liquid line restriction is low pressure in your evaporator. Liquid line restrictions can be caused by a restricted filter-drier, a restricted thermostatic expansion valve screen, a kinked liquid line, a bent lower condenser coil, or an oil-logged capillary tube. An evaporator that is starved of refrigerant will house a starved compressor and condenser as well. Liquid subcooling will also increase because of most of the refrigerant charge is housed in the condenser.

A blocked line will drastically affect refrigerant flow. The worse the restriction, the harder your system will need to work in order to adequately heat and cool your facility. This is extremely wasteful! Save energy and money by knowing how to diagnose your refrigerant flow problems. With no refrigerant to subcool, undercharged systems have a lowered mass flow rate, low suction and discharge pressures, and high superheat in the evaporator coil. With decreased refrigerant flow, the compressor’s draw will be very low. Symptoms for an undercharge problem are quite similar to a line restriction issue, except the latter usually shows signs of subcooling in the condenser, whereas an undercharged diagnosis does not. On the opposite side of the spectrum, if your refrigerant flow problem is the direct result of an overcharged HVAC system, it will have high condensing temperatures, increased amp draw, and higher head pressures. If your system is more than 10% overcharged, the liquid may enter the suction line.
