Buzzing Noises in AC Units



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. 

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 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. 

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.

Preparing Your HVAC Unit for Summer



Preparing Your HVAC Unit for Summer Heat!

It’s starting to get warmer, which means the Sacramento heat will be here before we know it! We’re just as excited for summer as you are. As you put final touches on your plans for summer, don’t forget to get your HVAC system ready for the heat waves. In this article, the best residential ac company in Placerville shares some simple tips for preparing your HVAC unit for summer.

Change the Air Filters

Summer is a very demanding season for HVAC systems, and one of the easiest ways to ease the work of the system is by replacing the air filters.

When filters are dirty, the entire system has to work a lot harder in order to circulate conditioned air throughout your home. This leads to the use of more energy than is necessary, and the system components are put under added strain that can make them fail prematurely.

Clean filters avert these problems, and they also serve the added benefit of keeping the ductwork free from contaminants like pollen and dust.

If you aren’t sure about how often to change the filters, talk to our service techs at Gilmore Heating and Air.

Clean the Condenser Coils

The grill-like sections on the outdoor unit of your AC are referred to as condenser coils. They play a crucial role in transferring heat, and once clogged, the proper functioning of your HVAC unit will be compromised.

HVAC repair professionals in Placerville, therefore, recommend that you clean these coils as you prepare the unit for summer. Use a garden hose to get rid of all the dirt and grime that had accumulated on the coils.

Keep the Surrounding of the Outdoor Unit Clean

If you check the manual of your HVAC unit, you will notice that the manufacturer recommends a certain clearance (of about 2 feet) around the outdoor unit.

Sacramento HVAC maintenance experts say the clearance is important in allowing airflow around that outdoor component. So, to get your outdoor unit prepared for summer, you should remove any debris, mulch, foliage, and any other objects that are too close to the unit.

Dry vegetation is particularly problematic because it poses a fire risk, and it can also attract rodents to nest in the condenser unit.

Replace or Repair Damaged Pipe Insulation

Placerville HVAC technicians point out that there is a suction pipe which links the outdoor unit to the indoor HVAC unit. If the insulation on this suction pipe is damaged, then your home will not get as much cool air as possible.

According to Tureks Plumbing, a plumbing company in Appleton, WI, says that pipe problems are bound to happen at some point. Like many home problems, the suction pipe insulation is normally damaged due to normal wear and tear, humidity, or even pests. No need to worry, contact our Sacramento HVAC technicians at Gilmore HVAC for a repair or replacement. Our team will have your central ac unit functioning at its best just in time for summer.

Schedule Its Annual Maintenance

Having a professional from Gilmore Heating and Air perform scheduled maintenance on your HVAC unit is worth it. Our heating and air tune-up services ensure that the HVAC system will continue to work when you need it most. You don’t want your HVAC system to develop a serious problem in the heat of the summer, do you?

Invest in a Programmable Thermostat

If you don’t already have one, now is the time to install a programmable thermostat before summer sets in.

The summer months are characterized by a lot of outdoor activities and travel. A programmable thermostat can come in handy to ensure comfortable conditions in your home without breaking the bank.

Ask your Folsom AC service technician for advice on the most suitable programmable thermostat. You can control the HVAC system P on the go! 

Consider Updating Your Unit

Has your HVAC unit been breaking down frequently, or is it more than ten years old? Now maybe the right time to upgrade to a newer model. Gilmore Heating and Air will provide their expert opinion about the best energy-efficient ac systems around. Don’t wait until your central ac system breaks when it’s over 100°F outside!

Dangers of Not Fixing an Air Conditioner



When an air conditioner doesn’t work properly, people become frustrated. Their frustration grows when they think about spending money on repair work. While worries about cash flow are understandable, also realize that a failing air conditioner presents hazards. Some dangers are serious ones.

A Faulty Air Conditioner Can Cause a Fire

Any electronic device that isn’t working properly may present a fire hazard. Air conditioners that spark or make crackling sounds are likely indicating a high risk for causing a fire. Some fire threats may not be noticeable to someone who doesn’t work with air conditioners and their wiring. Take that as a reason why calling in a repair pro makes sense. Gilmore Heating Air & Plumbing⁣ has provided air conditioning repair services in Placerville, CA, since 1979.

The Air Conditioner Might Trip the Circuit Breaker

Once a malfunctioning air conditioner takes out the breaker, all the other electrical devices in the house can go out. Loss of electrical power could put you and family members at risk when reliant on a device plugged into an outlet. What if flipping the breaker switch doesn’t turn everything back on right away, if at all?

The Interior Becomes Blazing Hot

Without a steady supply of cold air, a home’s interior temperature goes up. Staying in the house could become more than uncomfortable. People exposed to excessively hot conditions may face threats to their health. An air conditioner doesn’t need to go entirely out to create a hazardous situation. Decreased performance may be all that’s required for the temperature to skyrocket.

The Electric Bills Go Up

You won’t save much money if the trade-off to delaying repairs means higher electrical bills. An old, faulty air conditioner can turn out to be a shocking drain on your power. A minor fix might lead to more efficient performance and a lower electric bill.

Don’t suffer any troubles with a broken air conditioner. If you live in the Sacramento area, call up Gilmore Heating Air & Plumbing⁣ to request a fix. In addition to HVAC services, Gilmore Heating Air & Plumbing⁣ also offers plumbing services.

How to Choose the Right HVAC Contractor



With an influx in the number of HVAC contractors, finding one can be an uphill task without having the essential comparison criteria. The silver lining is that this guide intends to help you settle on the right HVAC contractor. Here are a few areas worth considering when comparing HVAC contractors.

Reliability

What current and previous clients are saying about a particular HVAC contractor should have a significant impact on your final decision. Those contractors with a satisfied clientele ought to be at the top of your list, as hiring them is likely to result in you joining the satisfied clients’ list. However, contractors with a significant number of dissatisfied clients are likely to frustrate you.

You can establish the reliability of a contractor by looking at their online reviews. Alternatively, you may ask around to see the kind of referrals they have. You may also choose to look at their licensing, as obtaining a license is an endorsement of their practices by the issuing body.

Cost

In most homes, the air conditioning system is the most expensive item. Therefore, proactive steps need to be taken to ensure that it’s taken care of so that you don’t incur the expense of purchasing a new model.

When choosing an HVAC contractor, don’t just settle on the one with the lowest cost. Instead, choose one that offers the best services within your price range. The contractor should come to your premises before quoting a price since there are other factors to consider, such as your space and home layout.

Additionally, if they offer to look at your entire system, then they might save you unnecessary costs. Before making a repair or replacement decision, ensure that they’ve walked you through your various options.

Efficiency

Air conditioning systems come in different models. Each model consumes a unique amount of energy. More efficient models are being developed as the years progress; hence, your chosen HVAC contractor ought to be familiar with their evolution and the efficiency of each model. The contractor should also be familiar with the federal government’s Energy Star-rated models.
