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.

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!

What Causes AC Freeze-Ups?



When ice forms on air conditioning units, it robs them of their ability to cool. These freeze-ups can lead to expensive repairs. That’s why it’s critical to understand the causes of freeze-ups and the steps you can take to prevent them.

Common causes of freeze-ups include:

  • Dirty filters
  • Dirty evaporator coils
  • Low refrigerant levels
  • Closed-off supply registers

As it cools your home, your AC unit condenses water vapor into liquid that drains outside. When airflow is impeded by a dirty air filter or other obstruction, water ends up freezing on the evaporator coils before the condensed water can be drained away. The AC still runs, but doesn’t properly cool, and uses more electricity. Running your AC with ice on the coil can result in serious damage that requires repair or replacement of the compressor, the most expensive component in your system.

Thankfully, there are steps you can take to prevent AC freeze-ups.

If you see ice forming on the outdoor unit or pipes leading from the compressor, check your filters. Blocked or closed vents can also impede airflow, so make sure that yours are open and free of blockages.

Other common causes of freeze-ups include faulty fans that don’t circulate air through your ductwork, faulty thermostats, and low refrigerant levels. Low refrigerant levels make the coils too cold, preventing the system from absorbing enough heat, leading to a freeze-up. Since air conditioners do not burn refrigerant, low levels indicate a leak. Locating a leak is work for a licensed technician, who will likely need to recharge your refrigerant.

Cold weather is another cause of freeze-ups in certain regions. When nighttime temperatures drop below 60 degrees Fahrenheit, you should switch off your AC and open windows, or install an ambient temperature control, which allows air conditioners to operate properly in lower temperatures.

Annual maintenance tune-ups are your best defense against freeze-ups. These checkups should include cleaning both indoor and outdoor coils, checking and replacing air filters, a check of refrigerant levels, and a variety of other important elements of your system.

If your air conditioning system isn’t operating properly, or hasn’t been looked over by a professional recently, it’s time to call the experts at Gilmore. Our trained technicians will take all the steps necessary to ensure that your AC unit doesn’t experience a freeze-up or other breakdown when you need it most during the hot days ahead this summer.
