Hearing Odd Sounds?

Loud vents? Air conditioner unit making a loud humming noise? Some noises are normal, such as a quiet hum or the sounds of air whooshing through the vents, but sometimes HVAC systems make strange noises and can become disruptive annoyances in the home. This doesn’t have to be the case. Check out these common causes of noises in an HVAC system and what you can do about them:

COMMON HVAC NOISES

Humming

An HVAC system that is running normally will make a soft humming noise. But if it’s more similar to clanking, that’s a sign that something is wrong. While normal humming could be from loose parts, such as the blower motor fan, loose blades, or loose pipes that are rubbing together, louder humming noises could be the result of loose wiring, circuit breaker overload, or failed condenser fan motor.

Clanking-like humming noises are a bit more serious because loose parts, if not addressed, can cause costly damage to your system. Your best bet is to turn the system off and call your technician.

Rattling

Hearing a rattling noise coming from your HVAC system could mean a few things. If it originates from the outdoor unit, chances are you have some kind of debris in the system, such as a twig. (While the grate will protect your system from most large debris, it’s still possible for small things to get through.)

Turn your system off and cut the power to the unit, then remove the debris. If you see visible damage to the condenser coils, compressor, or fan, call your HVAC technician. If the rattling seems to be internal, from a furnace or other internal component, turn the system off and call your HVAC technician since removing the obstacle isn’t as simple.

Hissing

Hearing a hissing noise most likely means air is escaping from your system. If the noise is coming from the walls, there’s a good chance your ducts are leaking. Not only can this cause noise, but it also wastes money because the air that should be circulating throughout your home is leaking into the walls.

Duct repair isn’t really a repair that homeowners can do on their own, so if your system is making a loud hissing noise,  call a technician. However, if the hissing is light, it could originate from your air vents. Typically when you hear this noise it is because your filter is not “set” right or you have the wrong size filter which is creating the gap in the seal. If this is the case, the air is squeezing past the filter or around it, instead of being pulled through it. This is a simple fix that starts with ensuring the filter is the right size and is placed correctly, leaving no room for gaps.

ADDITIONAL HVAC NOISES YOU COULD BE HEARING

Loud Whistles or Screaming

Hearing a whistling or screaming noise from your HVAC unit likely means that you have either a refrigerant leak or an excessive amount of internal pressure building up. Both of these causes are dangerous, so you should call an HVAC contractor as soon as possible.

Clicking

When you are turning your unit on and off, you are going to hear clicking noises. However, if you are hearing loud clicking coming from inside the cabinet of your HVAC you should be concerned. Most of the time this means that your capacitor is on its last leg. A poorly functioning or failing capacitor can be detrimental to your entire HVAC system. You should turn off your unit and call an HVAC professional to help you in this situation.

HVAC SYSTEM NATURAL NOISES

Keep in mind that your HVAC system is exactly that – a system. As it works, it will make noise. Hearing the motor running or humming, as wells as the fans blowing or air moving through the vents, is totally normal. However, unnatural sounds like rattling, hissing, or clanking, or the sounds becoming loud enough to be disruptive, can be signs of problems.

As with anything else, regular maintenance tune-ups, changing air filters, and other general repairs are the best way to avoid this, as well as knowing what sounds are normal and which ones are cause for concern.

TIPS FOR PROLONGING THE LIFE OF YOUR HVAC SYSTEM

HVAC systems can be a costly investment, one most homeowners should only have to make a few times in their life. The average system lasts about 15 to 20 years, and there are several things homeowners can do to maximize the life of their system and get the most out of their investment.

  • Pre-season cleaning and check-ups. It’s important to get your system cleaned and checked before the start of each season, generally once in the spring (for cooling systems) and once in the fall (for heating systems). This will catch any problems before the season starts and ensure your system runs smoothly. Schedule maintenance cleaning and check-ups early to ensure you have a quality visit from a licensed technician.
  • Checking air filters regularly. Clogged or dirty air filters can restrict the flow of air to your HVAC system, which creates extra stress for it by making the system work harder. This can cause costly damage to the blower motor because it has to work harder. Checking filters regularly can help avoid the build-up of dirt or dust, ultimately causing less stress on the motor and prolonging the life of your HVAC system.
  • Inspecting your equipment. Regularly inspecting your HVAC equipment can help catch small problems before they turn into big ones. While you’ll want a technician to inspect your ducts for air leaks and maintain your equipment, there are things you can check yourself. Keep an eye on any equipment that is vulnerable to excess corrosion or wear and tear. In the case of central air conditioning systems or heat pumps, any parts of the system that are located outside the house need to be visually checked for damage or a buildup of leaves and debris regularly. Out of sight, out of mind can’t become a habit, as the systems need to be checked even when not in use! In addition, every homeowner should regularly check for leaks in outdoor equipment. For example, finding an oily substance on outdoor surfaces could indicate a refrigerant leak, which can be a costly and damaging problem if not caught early.
  • Give your system a break. For a lot of homes in America, your HVAC system runs 24 hours a day, seven days a week. That’s a lot for any system to handle. Giving it a break can help to keep your system from being overworked and prolong its life. Installing and using a programmable thermostat can help with this, because it will allow you to adjust your temperature at night or when you aren’t home to a temperature that isn’t too high or too low. This way, when you return home, it’s less work on the system to get your house back to the ideal temperature. Overall, that slight ‘break’ for your system will make a big difference when it comes to the stress on it in the long run and will help you to get the max savings possible. There’s no way to predict or guarantee the life of an HVAC system, but with these tips you can keep your system running smoothly and efficiently, prolonging its life and helping you get the most out of your investment.

HVAC at Christmas

With 2020 coming to a close, it feels like now is the time to relax a bit and enjoy the holiday (safely, of course). Some people have noticed an uptick in their winter allergy symptoms, though. The reason may be a simple one: your Christmas tree.

Whether you opt for getting a live tree or are pulling an artificial one from storage, there are some things you should be aware of. Live trees are often in the elements, causing mold spores to have an opportunity to land on them, along with dust and any other pollens. These allergens can cause respiratory issues to worsen. Artificial trees not stored properly can have mold and mildew issues, as well.

What should you do? Well, one thing to do, especially with live trees, is to spray them down and then blow dry them before bringing them inside. This will usually get most of these irritants off the tree. You should also make sure the ornaments you use have been stored in a good place (as the issues with artificial trees can be seen in ornaments, as well).

On top of that, make sure your HVAC system is up to date and working efficiently. Check your filters, if you haven’t done so already. Of course, keep Air Handlers in mind for your HVAC maintenance needs!

Fall Weather Tips

The weather has changed and it’s obvious. It almost seems like we went from decently cool to needing our heaters with a snap of someone’s fingers! As always, make sure you have your system checked and that you’re good to go for the rest of the season (and call Air Handlers if you notice problems).

While your heater can help keep your home warm, you may be wondering about what you can do to make sure that your heater doesn’t work overtime. If so, here are a few simple tips we have to help your system work smarter, not harder.

Curtains, curtains, curtains: While it seems simple, this is easy to forget or overlook. When the sun is out and shining, open the curtains facing the sun so that some natural heat will be pulled into the house. Of course, closing the curtains on cloudy days or after dark will act as an extra bit of insulation to keep some warmth inside.

Maximize the flow: Make sure that warm air from your vents can move as freely as possible. For instance, you may want to sit close to a vent for that warm air to hit you, but it is better to move your chair or couch so that the air can go as far as possible to more efficiently heat your home.

Block the cracks: While things like making sure windows are properly sealed are standard knowledge, you should consider blocking the spaces around your doors, too.

Tips for keeping COVID at bay indoors

The weather is changing and starting to cool off. For now, being outside is manageable thanks to fairly comfortable (if wet) weather. When the temperatures begin to drop, though, we will all be spending more time indoors.

Recent reports have stressed the importance of ventilation to help curtail the spread of COVID (especially as many areas begin attempting to hold in-school classes again). This discussion has, largely, focused on schools, stores, and large office buildings. What about at your home, though?

An efficient HVAC system is the best first step. Make sure your system is working properly and that the filters are taking particles out of the air. This will help circulate the indoor air, for the most part. Here are some other things you can do while the weather is still fair:

  • Oscillating fans: make sure that any fans set up to oscillate (and thus help circulate air) do not have the chance to blow from possibly infected people to others.
  • Window fans: placing fans in the windows to circulate air into a room can prove very helpful.
  • Air filters: We recently experienced very poor air quality due to smoke from wildfires. During times like this, opening windows is not possible. In these instances, air filters can be beneficial.

Is your filter ready for the warmer weather?

When did you last check/change your system filter? Changing your filter regularly and properly is important for indoor air quality, your family’s health, and the life of your heating and cooling equipment. Neglecting to change your filter results in poor airflow and decreased filtration power.

Many homeowners should change their disposable furnace filter once a month, but the bare minimum is once a season. That’s why now is a great time to go ahead and change it out properly. Do you know the correct way to change your filter?

  1. The first thing you need to do is find out where your furnace filter is located. Is it in your ductwork? Near your furnace? Inside the air handler or furnace cabinet?
  2. Next, find out what size filter you need along with the proper filtration power. Higher efficiency filters can eliminate dust throughout your home and block all sorts of harmful airborne contaminants.
  3. Correctly place your furnace filter. This is where knowing which way the arrow is supposed to face is important. Always make sure that the airflow arrow on your filter is pointing towards your furnace or air handler.

If you have questions or concerns about your furnace’s filter, or aren’t sure where your filter is located, call Air Handlers today. You don’t want to go poking around in your ductwork or furnace cabinet to try and locate your filter. When in doubt, call a professional!

Are you ready for a warm up?

It’s almost that time of year again. The weather is going to get warmer and you’re going to want a cool place to retreat to. Is your system ready for the weather change?

Clear away any debris. Gunk built up can restrict airflow. Restricted airflow to your condenser leads to increased utility bills.

Plan your garden around your condenser. If you’re planting a garden, or even considering expanding one, make sure you account for your HVAC equipment. You want to allow at least two feet of clearance around your condenser.

Controlling Your Indoor Air Quality

Spring is quickly approaching. With it comes an uptick in pollen and other allergens outside. What about inside, though? Pollen, pet dander, dust, and other allergens can easily get into your home. How can you avoid them?

1. Air Filters

The biggest thing to remember is to keep your air filter clean. Your air filters should be changed regularly. You can also have Air Handlers check your system to make sure it is working properly for your home.

2. Floors Floors Floors

Do you have carpet or wood flooring? Is one better than the other? When it comes to in-home allergens, not really. Certainly, carpet can hold onto dust and dander, but wood flooring can, as well (especially in any hard to reach areas, such as at the corners of the room or under low objects). One way to handle this would be regularly vacuuming. While this is a good step, you need to be careful how you approach it, since some vacuums could blow allergens back into your home. You should also consider having your floors professionally cleaned annually.

3. Venting About

If your home uses a furnace, stove, fireplace, or a similar item (which should cover most homes), then proper ventilation will help with indoor air quality.

Other “combustibles” (or products that create toxic particles in the air) include things like tobacco smoke. Avoid using these items indoors to help keep some particles out of the air.

Overall, start with your HVAC system. Have it checked by a professional and then make sure you change your filters regularly. Call Air Handlers Inc today for a system check!

Have You Changed Your Air Filter?

While it’s a simple question, changing air filters is one thing some people don’t always think about. Many people don’t think about their HVAC system until it stops functioning the way it should. When an HVAC system stops functioning properly, the culprit is often a clogged air filter.

HOW DO AIR FILTERS WORK?

Air filters are generally made of spun fiberglass or pleated paper and surrounded by a cardboard frame. They are inserted into a specific place in the HVAC systems and act as a barrier to prevent contaminants and other particles from circulating in the air, or from reaching sensitive parts of the system. Some of the common things that filters block are dust, pollen, lint, mold, hair, animal fur, bacteria, etc.

HOW OFTEN SHOULD FILTERS BE CHANGED?

This answer depends on the type of air filter you are using. Most manufacturers recommend that basic filters are changed every 30 to 60 days, but there are other circumstances that could affect that schedule.

  • A filter in a regular home with no pets should be changed every 90 days 
  • If your home has a single pet, the filter should be changed every 60 days 
  • For multiple pets, or if anyone in your home suffers from allergies, you’ll want to change the filter anywhere between 20 to 45 days
  • People in single-occupant homes with no pets, or those who own vacation homes that don’t get much use, can usually wait for 6 to 12 months before changing their filter

WHAT HAPPENS WHEN YOU DON’T CHANGE YOUR FILTER? 

When air filters are not consistently changed, they get clogged by the buildup of particles and contaminants that stick to the filter.  While the filter is designed to accommodate these minuscule items, the buildup creates an almost impenetrable barrier so that the air cannot completely flow through, which can ultimately cause multiple problems for the entire HVAC system.  

Higher Energy Bills

When the filter becomes clogged, air cannot easily flow through the system. This causes the whole system to have to work harder to distribute heat or air where it is needed, which increases your utility bills since the air is running for longer. 

Poor Temperature Regulation 

Since clogged air filters make the system strain to create airflow, warm or cool air cannot adequately go where it is needed. This means that some rooms could be too cold during the winter or too hot in the summer.

Health Concerns 

If the air filter is clogged and cannot trap contaminants as it did before, those things can end up back in the air that everyone in your home is breathing. Immediate issues could include headaches, itchy eyes or throat, and dizziness. If the air filters are not changed and the issues continue, the long-term effects could be respiratory diseases, heart disease, or cancer.

Furnace Failures

As the system is working harder to get around clogged air filters, it can cause the entire system to overwork and eventually break. If this happens, you’ll need to replace the entire system, which can be expensive. Air filters usually cost less than $40, so they are easy to replace frequently compared to replacing the entire system.

Clamped-Up Coils 

Evaporative coils, which help remove heat from the air to keep your home cool, can freeze up if they are overworked. With a clogged air filter, the air won’t flow over the coils correctly, which makes them stop working and leads to total system failure. Again, the price to fix this issue is greater than simply purchasing a new air filter every few months. Protect your HVAC system and your wallet by replacing the air filters on a regular schedule.
