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.
Fall is upon us, and that means the atmospheric pressure is changing as well. Atmospheric pressure is defined as the pressure exerted by the earth's atmosphere at any given point. During this change of the season, we all need to begin learning what this means for our heating and cooling systems, and even our pockets.
Every outside heating and air unit needs to be able to handle change in weather and atmospheric pressure at any given time. Seeing as internal pressure is important to how a HVAC unit runs, It is good to also considering the pressure around the unit itself.
There are a few signs showing that your unit is experiencing negative air pressure. The signs include but are not limited to; random drafts of air, whistling sounds including odd noises, unregulated temperature in various rooms such is too hot or too cold, and the air seemingly pulling your door shut before you can do it yourself.
The main cause of negative air pressure within home is when the pressure inside your home is lower than the pressure outside. This is directly affected by the atmospheric pressure. Negative air pressure can bring various dangers inside your home such as poor air quality as well as Carbon Monoxide poisoning.
Luckily, our family team at Rudd Heating and Air can help you understand the importance of pressure inside and outside of your home. We want to help and make sure that your home is as healthy as it possibly can be. Take some time today and give us a call so we can schedule a time where we can inspect your home and see if your HVAC unit is working properly and pressure within your home is where it needs to be.
There is nothing quite like the comforts of home, and at Rudd Heating and Air, we could not agree more with this statement. There are many ways the weather can affect our lives, and with no way to control what's going on outside, there are measures to take that will help you and the ones you love make the best of a bad situation. Hurricane season in South Carolina can be a stressful time, but with the right plan in place you can decrease this worry, and we are here to help.
Heating and air conditioning units outdoors are at high risk of damage during bad weather this time of year, so you’ll want to have precautions in mind before the threat of a storm.
To prevent flood damage, your unit should be off the ground or on a platform, usually built on a concrete slab or reinforced cinder blocks. If this is not the case, you will want to buy a fitted cover, or a tarp to secure around your unit, then surround it with sandbags or quick-dams to make sure the water can not reach the unit. Covers and tarps will also help protect against flying debris from directly hitting the unit, and possibly crashing through to the wires and mechanics inside. If you choose to cover your unit for these situations, it is very important that the power is turned off before and during the time it's covered.
Even with these precautions, there is no guarantee the units will survive unscathed, so it's safer if all power to your units are turned off to reduce risk of starting a fire and damaging your home.
Not everyone has the knowhow or the capabilities to do these things, so we are here to help. Our team here at Rudd Heating & Air have special kits for these situations, please be sure to contact us if you are looking for advice or assistance!
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!
The Importance of Regular Maintenance
Investing in an HVAC system is a big step for some homeowners. However, after they have taken the time to pick a system that is right for them and their home, they fail to keep up with maintaining the proper condition of the unit. At Rudd Heating and Air, we want you to understand the importance of maintaining your HVAC unit to ensure the quality of air as well as the longevity of the unit itself.
Did you know that keeping a regular maintenance schedule on your HVAC system actually helps lower your utility bills? Thats right. When you take proper care of your unit, it runs smoothly and efficiently inside your home which prevents your bills from skyrocketing from using too much electricity.
Another great thing about keeping your system on a maintenance schedule is continuing to have healthy air produced in your home. If a system is poorly maintained, the air you breathe could be filled with the impurities you wanted out in the first place. This ties into the efficiency of the system. If a unit is dirty and unkept, it is known to work 20% harder than a well maintained system. No one wants a system that is not doing the job it is meant to do at full potential.
Rudd Heating and Air is here to serve the community with any needs that arise. We want our customers to have as much knowledge as possible about their units in order to take proper care of them. If you have any questions regarding the care of your HVAC unit, or to schedule a maintenance visit, contact us today!
Air filters are one of the most important tools to keeping your home clean and efficient. Removing dust, pollen, and debris from the air you breathe is a staple when it comes to central heating and cooling.
For a new homeowner, filters may be at the bottom of the list when it comes to remembering how to keep a home efficient. The Rudd staff wants to help you understand air filter etiquette!
The first thing to remember when it comes to changing out air filters is when to do it! In order to keep the system operating at optimal efficiency, changing your filter is suggested every one to three months. That may come off as quite frequent, but this is your air we are discussing. Knowing you are breathing clean air is a priority.
The second is the type and size of filter you should purchase. At Rudd Heating and Air, our family can help you assess your ducts in order to find a filter appropriate for your unit! Measure the opening or reference from the filter already in place. This will make sure you do not waste money on incorrect sizing!
Finally, Installation. When removing your old filter, make sure you have turned your unit off completely. When open, remove the old filter and clean the vent cover from excess lint and debris. Check the filter for the orientation of the the air flow arrow. You want the arrow to point toward the duct work to instill proper filtration. Latch the clean vent cover closed and turn your unit back on. Lastly, properly dispose of the old filter.
Rudd Heating and Air wants you to feel confident in taking care of your home and HVAC units. Filter changes are crucial to the lifespan of your unit as well as efficiency. Stop by our office or contact us if you have any questions regarding HVAC unit or central heating and cooling system care!
