AC Freeze Up in Sacramento



What Causes an Air Conditioner to Freeze Up?

Is your AC unit frozen? Nothing good comes from an AC freeze up. It is expensive to fix and has the potential of causing more damage to the unit. Also, a freeze-up means that you will, for some time at least, pay for energy bills while your AC unit isn’t working how it should. Such a problem needs to be fixed fast. What then causes an AC freeze up in Sacramento? Our Sacramento heating and air specialists share the top reasons that could cause this issue in your home. 

Poor Airflow

Warm air from your house blows over your AC’s coils. The air keeps the coils from freezing while also cooling the air inside your home. If this fails, the coils will start to freeze over due to the super cold refrigerant inside them. Poor airflow can be caused by a number of reasons. They include: 

A Collapsed Duct 

The air inside your house is directed to the coils through a series of ducts. Any obstruction inside these ducts will prevent the warm air from reaching your coils. This will lead to an ac freeze up in Sacramento.

Bad Blower Motor

The blower motor blows air towards the coils. It also provides additional pressure to the air, which maintains a consistent rush of warm air whenever the AC unit is running. If the blower motor stops running, then air stops flowing and freezing starts. 

Low voltage to the Fan 

Sometimes, the problem will not be the AC unit but your electricity. Our friends at McQuillan Brothers, an HVAC company in St. Paul, explains that if the blower or fan will not run effectively if they are not receiving enough power. This will lead to an ac freeze up. 

A Clogged Air Filter 

The air filter is situated between the outdoor unit and the interior of your house. It traps impurities and allows clean air to enter your home. It also keeps the compressor coils clean. A dirty air filter prevents consistent airflow over the coils. This is why the air filter needs to be changed every 30-90 days. Contact Gilmore today for a Sacramento AC tune-up.

Blocked Coils 

An ineffective air filter leads to dust accumulation on the coils. The dust settles on the dump coils and cakes from the combination of dump surface and the dust. This creates an insulator effect, which prevents the warm air from reaching the coils and increases the cold temperatures inside the coils. 

Insufficient Refrigerant 

The refrigerant is responsible for transferring heat from the indoor unit to the outdoor unit where it is then dispersed. Its movement is aided by the compressor (outdoor unit), which compresses the gas turns it into a liquid. 

The liquid is then pushed through the circuit and into the house where it meets the warm air and turns into a gas as it absorbs heat energy. 

Low refrigerant means that the refrigerant will not absorb enough warm air to turn it into a gas. This ultimately leads to the freezing of the condensate on the coils, which will then form ice cubes and make its way to the outdoor unit. 

What to do when your Placerville AC Freezes Up

The first step should always be to switch off your thermostats. This stops the system and prevents the refrigerant from flowing. You can also turn on your fan to increase airflow, which will then aid in melting the ice. 

Call a Sacramento AC service company to fix the issue. Make sure they know what they are coming to fix. You can mention the ice so they can treat it as the emergency it is.

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.

5 Causes of One Hot Room in the House



5 Causes of One Hot Room in the House

One of the HVAC problems that we often get at Gilmore Heating and Air are complaints about having one hot room in the house even when the AC is turned on. Before this problem can be fixed, you’ll need to find the source of the problem. Here are the common causes of one hot room in the house.

Undersized HVAC Equipment

Over the years, the load that your Sacramento HVAC system is tasked with handling can change as different rooms evolve. For example, when you convert a bedroom into a home office, and you install electrical equipment there, the heat generated by the equipment may be too much.

Residential air conditioning company in Placerville says that as a system becomes undersized for the load, it has to bear, the furthest rooms from the air handlers will be the first victims to show insufficient cooling. Headwaters Construction Inc, a Sacramento commercial construction company, agrees that undersized HVAC equipment can play a big factor in properly cooling your space.

Gilmore Heating and Air techs will recommend the best option for you. For example, we may advise you to use ceiling fans or improve the insulation of your home. However, some cases may only be remedied by getting a bigger sized AC selected and installed by your Sacramento HVAC replacement technicians.

Warm Air Rising to Upper Floors

As you may know, cool air is denser than warm air. Consequently, warm air tends to rise while cool air occupies the lowest level in a conditioned space. This may explain why the rooms on the upper floor of your home are warmer than the rooms downstairs.

Residential AC service Placerville professionals can help to fix such a situation. For example, adjusting the air vents or dampers can deliver more conditioned air upstairs. Boosting attic insulation can also help, just as adding a ventilation fan in the attic can extract warm air. If all these conservative options don’t yield results, professionals may suggest that you install an HVAC system solely for the upper floor of your home.

Leaking Ducts

It is also possible that one room in your home is always hot because the ductwork is leaking. Such a leakage not only wastes energy but also creates room for other problems.

Fortunately, Gilmore Heating and Air have effective tools to test and establish which ducts are leaking. Thereafter, our residential AC maintenance personnel will seal and insulate the ductwork properly. 

Improperly Positioned Thermostat

The location of your thermostat will have a great bearing on the degree of comfort in your home. For example, if the thermostat is located near a heat source (behind an oven, for example), the sensor will get an inaccurate reading of the temperature inside the home. Therefore, you will get uneven cooling in the house.

Other unsuitable locations for a thermostat include close to exterior doors that are frequently opened. Your home’s thermostat shouldn’t be close to windows where direct sunlight reaches it.

When you complain about having a hot room in your house, Sacramento HVAC personnel will determine whether the location of the thermostat is ideal, in addition to checking for other possible causes. If the placement of the thermostat isn’t appropriate, we will relocate the device.

Dampers and Vents That Need to Be Adjusted

There has to be a balance in an HVAC system if it is to deliver satisfactory cooling throughout a building. However, renovations and alterations in the way rooms are used can throw this balance off.

For example, when a wall is removed during a remodel, the dampers and vents have to be adjusted to address this alteration. Otherwise, the bigger space created will not get sufficient cooling. 

As you can see, several factors can cause one room in your home to be hot. The best way to determine the cause behind this is by contacting your local HVAC company, Gilmore Heating, Air, and Plumbing. Our experienced professionals can fix the problem.

 

Main Causes of AC Failure and How to Prevent Them



The air conditioner is generally considered to be among the most important appliances in a residential property. Like any appliance, it’s prone to suffering from issues due to all of the parts and mechanisms that are included. As a homeowner, it’s essential to be aware of the main causes of AC failure and how to avoid them.

1. Low Refrigerant

The refrigerant in the AC system is used to remove the heat from the air as the interior setting is cooled. Leaks can often develop in the refrigerant lines, which means the air won’t get cool. This problem can be avoided by hiring a professional from a company like Gilmore Heating Air & Plumbing⁣ to perform a tune-up every six to 12 months. This will allow you to monitor the condition of the refrigerant lines.

2. Thermostat Issues

Your thermostat may eventually begin to malfunction, especially if it’s an old dial-type that’s not calibrated correctly. Your AC system may not be getting the right instructions from the main control system. The problem can be avoided by replacing an outdated thermostat early on or checking the manual to ensure the settings are accurate.

3. Issues With the Fan

A faulty motor or a lack of lubrication can prevent your AC fans from operating. To address the issue, hire a technician to lubricate the parts every six months with tune-ups that are scheduled. This will keep the fan operating properly.

4. Dirty Condenser Coils

Condenser coils are prone to getting dirty and accumulating grime. Once the dirt becomes too thick, the AC will break down or turn off frequently. Make it a point to clean the coils to improve the operation of the parts.

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.
