Buzzing Noises in AC Units

Buzzing Noises in AC units

Why is My AC Unit Making a Loud Buzzing Noise?

Oh no! Is your AC unit making a loud buzzing noise? Today on the blog, our HVAC experts share all of the common reasons for these type of noises, and what to do when this occurs.

Why is My AC unit making a Loud Buzzing Noise?

Nobody wants buzzing noises in AC units. The smoother and quieter the appliance is, the better for everyone. Unfortunately, your AC unit is not immune to mechanical issues. It will, every now and then, develop problems that require fixing. These issues are usually indicated through things like buzzing noises. 

Loud buzzing noises in AC Units are usually an indication of a problem that will require money to fix. Not to mention that problems cause inconveniences. What then, could be the problem when your usually quiet AC unit starts to buzz?

Our residential AC company shares what could be wrong with your AC unit if you hear a buzzing noise. 

Buzzing Noises in AC units

Faulty Compressor 

The compressor pressurizes and cools the refrigerant within the AC system. It is located in the outdoor unit and is integral in the circulation of the refrigerant throughout the entire system. A buzzing sound could mean that the compressor is not working properly or that there is a power problem on the outdoor unit. 

Frozen AC unit

Your AC unit will freeze if the refrigerant leaks from the system. McQuillan Bros, Twin Cities HVAC Contractors, urges customers to remember that the refrigerant used in the system is extremely cold. Leaks can happen due to a number of reasons. When they do, you are likely to hear a buzzing sound. 

Loose Parts 

Loose parts are normally accompanied by a buzzing and rattling sound. Your AC unit is likely to encounter a loose-parts problem as it ages. After all, it is not uncommon for your AC unit to vibrate when working. Loose parts such as bearings can lead to additional or premature wear throughout the system, which can, in turn, lead to buzzing sounds.

Missing or Damaged Isolation Feet 

Isolation feet are used to mount the compressor. The isolation feet are small and usually made of rubber to keep the compressor off the floor and keep it properly balanced. Continued use of the AC unit can lead to cracking or disintegration of the isolation feet, which interferes with the balance of the compressor. When this happens, you are likely to hear a buzzing or loud vibration whenever the AC unit is working. Luckily these can easily be fixed during your next Placerville HVAC service.

Electrical issues 

An electrical issue can also cause a buzzing noise within the AC unit. Sadly, there are many electrical issues that may result in this kind of noise. For example, the unit might undergo ‘electrical arcing.’ This happens when an electrical current misses its intended path and takes on other parts of the circuit. 

Other electrical issues that could lead to a buzzing noise within the AC include:

  • Loose wiring
  • A bad capacitor 
  • A faulty condenser fan motor 
  • Contractor relay switch on the outdoor unit

Dealing with a Buzzing Noise 

No one wants a buzzing AC unit in their home. Your AC system is complex, and it requires a combination of parts working together to provide you with the right conditions for your comfort. Therefore, the best way to deal with a buzzing noise is to switch off the unit and call a trained professional.

Repairing vs. Replacing Your AC

Repairing vs Replacing Your AC

Repairing Vs. Replacing Your AC System

Today on the blog, our HVAC professionals tackle a debate that many homeowners are presented with – repairing vs. replacing their HVAC unit. Our specialists share a number of factors to consider before you make the decision to repair or replace!

Repairing vs. Replacing Your AC System

Most homeowners prefer buying things that will last for a long time in their homes. The longer the item lasts while still providing service the better. An HVAC unit is always built to last.  A typical AC unit can last from 10-15 years. However, with time, you might be faced with the dilemma of repairing or replacing it. This is usually the case when you feel that it is not providing service as expected. Given everything involved in replacing your HVAC unit, it helps to take a moment and decide whether you really want to buy a new system. Below are a number of factors from our Sacramento’s Top hvac company to consider before you make the decision of repairing vs. replacing your ac. 

Repairing vs Replacing Your AC

Lifespan and Condition of the Unit

Chances of an AC replacement increase with time. The more you use it, the more it wears down. The system will be more likely it is to suffer from breakdowns. You might be forced to replace your AC system as the number of repairs increases with time. 

Additionally, the ENERGY STAR program by the Department of energy and the EPA recommends that AC systems that are older than 10 years be replaced. Headwaters Construction, Sacramento commercial construction company explains that this is because, with time, these systems lose their efficiency. This then leads to a rise in energy bills. 

Health and Safety Concerns

Replace your HVAC unit if your contractor says it is safer to do so. There are a number of factors that would determine whether your AC unit poses a hazard. For example, if the heat exchanger on the furnace is cracked, then it makes sense to replace the unit. A cracked heat exchanger will lead to the leakage of carbon monoxide which is highly dangerous to humans. A leaking HVAC system might also introduce humidity in the house. Humidity provides the perfect conditions for mold and mildew to grow within your house. 

You might also be prompted to replace the AC system if the cost of repairing to prevent potentially hazardous situations is higher than that of replacing it. 

Heating Effectiveness 

An effective HVAC unit will ensure that your home is comfortable to live in all year round. Additionally, it will guarantee that you do not waste your money. Effectiveness in an AC unit is measured by how much it is able to regulate the atmosphere in all your rooms. 

Therefore, if your AC unit is not providing enough heat for all rooms, our Sacramento HVAC company explains that it is not effective enough and might warrant an HVAC replacement. This is usually the case with older systems. This would require that you replace it with newer and more efficient systems. 

With time, also, manufacturers develop newer and more efficient systems that will reduce your energy spending. A much older system might not match up to a newer system’s efficiency. 

Recommendation by Your Contractor 

Are you still wondering whether to go for HVAC repair or replacement? How about talking to a professional? Your Sacramento HVAC contractor should be able to provide you with the right answers after examining your system. At Gilmore Heating Air Plumbing Home Services, we will offer you useful advice and provide quality ac repair, ac tune-up, and ac replacement services.

Common AC Problems

A functioning air conditioning system is essential as we head into these hot summer months… However, like any home appliance, problems can arise with your air conditioning system. Our HVAC professionals share the most common AC problems to anticipate. From faulty fans to dirty condenser coils, there are a variety of problems that could occur. Check out our weekly blog post so that you can be prepared for any AC related issue this summer.

Most Common AC Problems

A functioning air conditioning system is one of the best things to have in a home all year round. Their invaluable benefits allow people to enjoy the best atmospheres and bring an added level of comfort in homes. Like every other appliance in your home, an AC system can encounter problems. The problems can vary and they will definitely cause a lot of inconvenience. Our Sacramento HVAC company shares a number of the most common AC problems to expect. 

Most Common AC Problems

Frozen Evaporator Coils 

The work of evaporator coils is to absorb heat from the atmosphere and lower room temperature. Usually, evaporator coils freeze due to a lack of system airflow caused by a faulty air handler or a closed air register. Lack of airflow on the evaporator coils will prevent it from absorbing enough heat from the atmosphere. This, in turn, allows the condensation accumulated on the coil to freeze over. 

Faulty Fan 

An AC unit normally has two fans. One fan blows cool air into your home. It is located inside while the other one blows air over the condenser coils thus directing hot air outside. If any of these fans malfunctions, then the AC unit will cease functioning properly. 

Faulty fans can be as a result of debris, especially on the outside fan, a faulty motor, insufficient lubrication, or worn belts. This, in turn, hinders the amount of air flowing in and out of your space and can lead to further damages to the central AC unit. If this is happening in your home, contact Gilmore Heating, Air, and Plumbing immediately. 

Leaking Ducts 

There are ducts leading from the air conditioning unit and into your house through the walls. These ducts are responsible for carrying cooled air and distributing it across your entire space. However, due reasons such as interference from rodents or damages from any intense physical work happening at home, the ducts may start to leak. This leads to the cool air being deposited inside the walls instead of being driven to the rooms. Such a scenario will cause the AC unit to work harder to supply cooled air thus leading to increased energy bills. 

Clogged Drains 

Drains help remove excess water from your AC unit and expel it outside. The water comes from the humidity in the atmosphere which is converted into water before being drained outside. When an obstruction happens along these drains, mainly due to dirt and debris, the water can accumulate within the system and cause problems inside your house. 

Turek’s Plumbing, plumbing company in Appleton, WI explains that these problems can range from water leakages from the ceiling, stained ceilings, a dump-moldy smell around the house, a failing AC unit due to a triggered water safety switch, or a full condensate pan. 

 

Dirty Condenser Coils 

The condenser coils are found in the outdoor unit. Their work is to remove hot air from your house. Dirt on the coils caused by debris, dust, and grime will affect the condenser by reducing the amount of heat expelled from your interior. This, in turn, affects the efficiency of the whole unit making to work harder and increase the wear and tear of the unit’s parts. Sometimes, a dirty condenser can lead to a complete system failure. 

Most, if not all, HVAC problems are easily fixable. All you need is to find the right HVAC repair company to get your system running again. Call Gilmore Heating and Air for your residential ac service in Placerville and enjoy unmatched professional service.

Clean Air in Your Home

Clean Air in Your Home

Achieving Clean Air In Your Home

Clean air in your home is so important for the overall health of everyone in your family. Today on the blog, our HVAC Technicians discuss achieving clean air in your Sacramento Home.

Achieving Clean Air in Your Home

If you’re like most homeowners, you probably don’t stop to think about your home’s air quality. What many Sacramento homeowners don’t realize is that your HVAC system directly affects your indoor air quality. Over time, mold and bacteria will start to build up, which eventually is blown into the air you breathe. At Gilmore Heating, Air and Plumbing⁣, we put the safety and health of our customers first. In this article, you’ll learn a few tips on how to keep clean air in your home.

Clean Air in Your Home

How Can You Improve Air Quality?

One of the best ways to keep your air quality clean is by staying up to date with your HVAC tune-ups. You’ll see a drastic difference in your air quality when your heating and air condition unit is properly cleaned and maintained. When searching for a Sacramento HVAC company near me, keep an eye Gilmore Heating and Air special offers

UV Lights

UV lights are another great way to improve your home’s indoor air quality. Many Sacramento homeowners are shocked to learn how much mold and bacteria are in their home. Professionally installed Ultraviolet or UV lights can help kill bacteria and allergens by sterilizing the air supply. UV lights are commonly used in laboratories, hospitals, and food manufacturing plants for better air quality and sterilization.

By having UV lights installed inside your HVAC system, you can enjoy the same sterile air quality required by hospitals to help keep patients healthy. Ultraviolet lights can be placed near the air handler to kill bacteria and viruses, so they don’t get dispersed into the air you breathe. And they can also help keep the evaporator coil mold-free, as well as purify and sterilize the air coming from return vents and air ducts.  

Upgrade Your Air Filtration

Air filters with higher Minimum Efficiency Reporting Value (MERV) ratings are available to improve your home’s air quality. These higher MERV filters are more effective at trapping viruses, bacteria, and other contaminants than standard air filters to better protect you from the flu. But before you replace your standard air filter with a higher MERV rating filter, call Gilmore to find out which filters work best for your AC systems. 

We will never stop stressing the importance of changing your air filter regularly. That’s because old dirty filters hold germs that can be filtered throughout your home. A clean, strong air filter can prevent bacteria and germs from passing through your home. So, it’s important to change your air filters regularly if you really want to remain healthy.

Humidity Control

Indoor air humidity can affect the survival of germs and viruses in your home. We asked our friends Tureks Plumbing, a plumbing company in Appleton, WI, about humidity. The professionals warn that high humidity can cause an increase in mold and mildew growth. This could put your home and your family’s health at risk. Your HVAC system plays an important role in humidity control. So contact us today for an inspection and regular maintenance, you can keep humidity control in check. If your HVAC system is poorly maintained, your indoor air quality suffers. Have your system inspected by one of our Sacramento HVAC technicians to make sure it’s keeping clean air in your home.

System Balancing Can Improve Your Air Conditioner’s Performance

Comfort—it’s why you have a central heating and air system. But if all rooms don’t cool or heat equally, your home may be a candidate for system balancing.

System balancing is all about carefully balancing airflow throughout your home.

Balancing your system means measuring and adjusting the volume of airflow into each room through a system of ducts in your home. Creating this balance is critical to maintaining comfort. As hard as this may be to believe, it’s not uncommon to find systems 30% to 50% low on airflow.

A number of tests using specialized tools are used in balancing your system:

  • Air balancing hoods measure the amount of air at each grille.
  • Hygrometers measure system temperature and humidity.
  • Manometers measure system pressures.

Static pressure is one of the key vital signs of your comfort system. Think of it like a doctor’s visit. Someone always checks your blood pressure. That’s your system’s static pressure. Measuring static pressure helps identify any significant blockage or leakage. Cracks in your home’s infrastructure, such as pet doors and poorly sealed windows and doors, all contribute to temperature loss or gain.

By measuring airflow, a certified technician can see your system’s performance, and then diagnose, repair, and balance the duct system for maximum performance. Many systems have dampers located at specific duct points. These dampers slide open or shut to increase or limit the airflow through certain ducts. Adjustments can increase balance.

Ductwork must also be checked for leaks, holes, and crushed areas.

Your ductwork must be manually checked for any holes or crushed areas. The more accessible your ducts, the easier it is to perform balancing. Leaking in your ducts leads to a loss of air supply, which will directly affect the temperature in your home.

Because rooms are different sizes, different amounts of air are needed to heat or cool one compared to another. This sometimes means adjusting registers. A small room may only need its air register opened halfway to heat or cool it, while larger rooms may need registers fully opened to achieve the same temperature. The end result:

  • The same temperature in every room
  • Cleaner air
  • Better humidity control
  • And real energy savings with the equipment you have on hand

If the rooms in your home aren’t cooling evenly when you run your air conditioner, with one room sweltering while the next sends you running for your sweater, then your central AC system is due for system balancing. Call the experts at Gilmore to schedule a system balance for your home, and start enjoying the full level of comfort that your AC has to offer.

Maintenance Tips to Keep Your HVAC System Running Effectively

We’re getting towards the end of the summer, but here in Central California we still have another month or so of hot weather to get through. You’ll need to keep your air conditioner running strong for a few more weeks, and perhaps more importantly, you’ll want to make sure that your HVAC system as a whole is set for success, no matter what the weather.

Chances are that you’ve been running your air conditioner a lot the last few months, which means that conditions are primed for ductwork contamination.

 

Ductwork is one of the most vulnerable parts of any HVAC system. Moisture accumulation due to leaks can result in mold contamination, and debris buildup can choke off air circulation and eventually overwork your system.

Have you had Gilmore perform a checkup on your HVAC system? Then now is the time to give us a call at 888-868-2316, or send us a message with our appointment scheduler form to take advantage of our special promotional pricing before it ends!

Even if you’ve had your HVAC system checked recently, it’s always a good to have preventive maintenance program for your air ducts—whether or not you decide to have the air ducts in your home cleaned. It not only helps prevent contamination—it provides great peace of mind knowing that your indoor air quality is the best it can be.

8 Ways to Prevent Dirt from Entering Your HVAC System:

  1. Use the highest efficiency air filter recommended by the manufacturer of your heating and cooling system.
  2. Change filters regularly.
  3. If your filters become clogged, change them more frequently.
  4. Be sure you do not have any missing filters and that air cannot bypass filters through gaps around the filter holder.
  5. When having your heating and cooling system maintained or checked for other reasons, be sure to ask the service provider to clean cooling coils and drain pans.
  6. During construction or renovation work that produces dust in your home, seal off supply and return registers and do not operate the heating and cooling system until after cleaning up the dust.
  7. Remove dust and vacuum your home regularly. (Use a high efficiency vacuum (HEPA) cleaner or the highest efficiency filter bags your vacuum cleaner can take. Vacuuming can increase the amount of dust in the air during and after vacuuming as well as in your ducts).
  8. If your heating system includes in-duct humidification equipment, be sure to operate and maintain the humidifier strictly as recommended by the manufacturer.

How to Keep Moisture from Building up in your HVAC Ductwork

When water builds up in ducts, this can promote biological contamination, such as mold that is unhealthy and even dangerous to breathe. That’s why it’s very important to make sure there is no moisture in your air ducts by carefully controlling the environment.

Moisture can enter the duct system through leaks, or if the system has been improperly installed or serviced. Research suggests that condensation on or near air conditioner cooling coils is a major factor in moisture contamination. So, condensation or high relative humidity is an important indicator of the potential for mold growth on any type of duct.

3 Smart Tips for Controlling Moisture:

  • If you know something is wrong, don’t delay in getting your A/C system repaired. Promptly and properly repair any leaks or water damage.
  • Pay attention to cooling coils which remove water from the air—they can be a major source of moisture contamination of the system that can lead to mold growth. Make sure the condensate pan drains properly. The presence of substantial standing water and/or debris indicates a problem requiring immediate attention. Check any insulation near cooling coils for wet spots.
  • Make sure ducts are properly sealed and insulated in all non-air-conditioned spaces (e.g., attics and crawl spaces). This will help to prevent moisture due to condensation from entering the system and is important to make the system work as intended. To prevent water condensation, the heating and cooling system must be properly insulated.

If your AC system isn’t working at its peak capacity, it’s probably time for a checkup, especially as the weather starts to turn in the next couple months and increased moisture raises the odds of indoor air quality concerns.
