What Causes my HVAC System to Freeze?
At Rudd Heating and Air, we understand that here in the south, having an HVAC unit that runs smoothly is incredibly imperative. There are many reasons why your HVAC system is giving you trouble. HVAC systems sometimes freeze themselves, creating problems for the homeowner. The following are a few reasons why your HVAC unit may be freezing:
As you can imagine your HVAC system needs proper airflow to work. The first thing you can do in order to check the airflow is to make sure that your filters are clean. The next is to check all of the vents in your home and ensure air is flowing freely through the vents. Don’t block or close any vents as that can cause air restriction to the unit.
The refrigerant used in HVAC units changes its physical properties due to pressure change. This pressure change causes the refrigerant to act differently and therefore, no longer perform effectively. The change in the refrigerant pressure can cause your AC components to freeze up.
Failed Blower Fan
A blower fan on an AC unit helps move the cool air throughout the home and push the warm air back outside. In order for the blower fan to work effectively, there needs to be a balance of airflow in air pressure. If your blower fan is damaged it can also cause the line to freeze.
It is imperative to keep your HVAC system as clean as possible. We have talked about in past blogs of proper maintenance for your HVAC system. If the coils within your HVAC system are dirty it can cause the water pulled from the air to condense and freeze onto the coils themselves or pipes within the HVAC system. Signing up for by annual maintenance can prevent this.
At Rudd Heating and Air, we can take care of all of your HVAC needs in order to prevent your system from freezing. If you have any other questions or concerns please contact Rudd during the week.
If living in South Carolina has taught us anything, it is that is can get really, really, hot! Here in Charleston, Air Conditioning is a welcomes appliance in any home. As with most, consumers have options of different types of appliances. When it comes to Air Conditioning, there is a choice between electric or gas. Even though these categories make it seem as though the units are run only on either or, that isn’t the case. It is just which is used more in the different systems.
Completely electric air conditioner will use that energy to support the use of both cooling and heating. A predominantly electric unit will have a condenser and a furnace. The split system causes warm air to be pushes outwards in summer, and warm air to be pushed inside in the winter. Having this split systems is crucial to home owners because you will want your homes to be comfortable and livable.
Like we states before, this title does not actually mean the unit will only use gas. The furnace will be what is fueled by gas, yet the unit will still need some level of electricity to function the condenser.
While the titles of these units make it seem as though they are an either or case, they still incorporate the same equipment. Heating and cooling systems are the most expensive part of the utility bills for most Americans. The costs of gas and electric will both fluctuate over the corse of the time you have a unit, so in a way, whichever you choose has the potential to run the same amount of money over time if kept at a reasonable temperature.

Noisy Equipment? Here’s Why
There is constant noise around us at all times, but when there is something in your home making a noise you have never heard before— you start to worry. If your home is making a noticeable noise and you think it’s your HVAC system, call Rudd Heating & Air today! In the meantime, here are some reasons your HVAC system could be making that racket!
Does the noise sound like a bang, or even a pop? This noise could be your fan turning on and then stopping. It has to do with negative pressure within the duct. When the fan begins, the ductwork con-caves due to the pressure, and when it stops abruptly, it returns to it’s natural resting shape. This noise and movement of the ducts in your unit can be a sign of a clogged filter, flimsy equipment, and even improper sizing of your duct!
Is your HVAC uniting humming you a tune? A noisy transformer could be the serenader. All transformers make a humming noise, some louder than others. On the flip side, if the unit is not working properly, you may have a bad fan motor or capacitor and in need of servicing.
Does it sound like there is pieces of something being rattled, or maybe even a high pitched sound that gives you a headache? Heat pumps are typically the culprit. Some units have noisy parts such as check valves and metering devices. Once the air filter is checked, and you’ve just had enough of that terrible sound, give us a call and we will service it!
Rumbling noises specifically for gas or oil systems? We take extreme precaution when it comes to this noise with these types of units. It is extremely important that you call for service immediately if you are hearing these sounds because it can be a warning sign of combustion. Turn the equipment off.
Hearing a thump or a vibrating hum? Something is off balance! Particularly the blower wheel. This sound isn’t as disruptive as the others, but shouldn’t be ignored due to further complications.
Hearing a metallic scraping sound? Or perhaps metal hitting metal? Turn your system off as soon as you hear these noises. This sound is the worst of all the sounds described. This sound could indicate pieces of your unit are coming apart and shifting to places they should not be. Once you call for service and we see no signs of damage, we can easily place the parts back in their original positions, re-tighten, and fix the issue. In the possibility that parts are broken instead of solely being out of place, the parts must be replaced.
So now you have an idea of what that noise could be. That doesn’t mean you can go in and fix it yourself! Call our family owned and operated service, and Rudd and we will treat you like you’re a part of the family!
HVAC is an acronym for heating, ventilating, and air conditioning. An effective HVAC system allows the owner to have control of the thermostat and comfort in their home. The three design principles of an HVAC system include; fluid mechanics, heat transfer, and thermodynamics. For a normal household, the energy mostly consists of heating and cooling. The importance comes down to understanding which HVAC system will meet your needs effectively. The last thing you want is for your system to be using more energy than necessary!
H is for Heating
Heating options are available so a customer can choose what is best for their place. Furnaces operate on natural gas or propane, while boilers operate with gas or oil. It is good to take into consideration the product a system runs on before installment.
V is for Ventilation
Ventilation assists in the circulation of fresh air within a home. Air circulation allows the unit to expel air into every corner of the room or house. Without ventilation, the air would be stagnant and feel stuffy. Ventilation should be prioritized when selecting a unit.
AC is for Air Conditioning
Air conditioners come in many different shapes and sizes. Conditioners can be used in an entire house, or simply a single room. It is important to stay cool in the summer months, so the system should be chosen carefully. The different systems include central, evaporative coolers, and ductless mini split air conditioners.
