Do You Know the symptoms of heat stroke?

Do You Know the symptoms of heat stroke?


With the temperatures getting hotter, AC Dave Heating & Air would like you to know that heat exhaustion and heat stroke are preventable. Do You Know the Symptoms of Heat Stroke? Read on for some do’s and don’ts.

According to the CDC, signs of heat stroke, also known as hyperthermia, include:

  • Body temperature of 104 degrees Fahrenheit or more (40 degrees Celsius)
  • Fainting
  • Confusion
  • Fast and strong pulse
  • Dizziness
  • Skin that is hot to the touch. The skin may also be red, dry, or damp.
  • Upset stomach, nausea, or vomiting


Call 911 immediately if someone is showing heat stroke symptoms

 Heat stroke is a medical emergency. In the U.S., dial 911.

While you wait for help, the CDC recommends that you provide first-aid treatment:

  • Move the person to a cooler place out of the sun.
  • Cool the person by applying cold, wet clothes or by placing the person in a cool-water bath.
Do not delay care, even if you are worried that the person may contract COVID-19, the disease caused by the novel coronavirus. Hospitals are working to protect patients during the pandemic, for example, by limiting visitors and separating COVID-19 patients from others.
If a person shows heat stroke symptoms, do not force them to drink water or other fluids.


Know the symptoms of heat exhaustion

Heat exhaustion is a less serious condition than heat stroke. But without treatment, it can progress to heat stroke, according to Johns Hopkins Medicine. The CDC lists the following symptoms of heat exhaustion:

  • Heavy sweating
  • Cold, pale, and clammy skin
  • Fast, weak pulse
  • Nausea or vomiting
  • Muscle cramps
  • Tiredness or weakness
  • Dizziness
  • Headache
  • Fainting

The CDC advises you to treat heat exhaustion by taking these steps:

  • Move to a cooler place out of the sun.
  • Remove or loosen your clothes.
  • Cool yourself by applying cold, wet clothes or by bathing in cool water.
  • Take sips of water.
 Seek immediate medical help if you experience any of these problems:
  • You vomit
  • Your symptoms worsen
  • Your symptoms do not go away within one hour
 To reduce the risk of heat exhaustion and heat stroke, watch the forecast
 Heat exhaustion and heat stroke are more likely to occur when the weather is hot, so monitoring the weather forecast is an important prevention step. Keep in mind that asphalt and concrete absorb heat, so if you live in an urban area with many parking lots, buildings, and other structures, your block may be significantly warmer than other areas of your city. High humidity is also dangerous. On hot days, you cool down as sweat evaporates from your skin. But when the air is very humid, sweat evaporates from your body only slowly, which prevents it from cooling itself effectively. When you check the weather forecast, look for the heat index, a number that includes the effects of both temperature and humidity levels. If the heat index is 91 degrees Fahrenheit or higher, you should take steps to stay cool, according to the Mayo Clinic.
  • Make sure to drink plenty of water. Avoid caffeine.
  • Wear light-colored, loose-fitting clothing.
  • Avoid exercising outdoors during the hottest times of the day.
  • If you are playing, exercising, or working outdoors, take breaks to cool down under shade.
  • If you supervise people who are playing or working in hot weather, offer them plenty of chances to take breaks and drink water.

Seek shelter during heat waves. To stay healthy, your body needs a break from high heat and humidity. If you do not have air conditioning, seek shelter in air-conditioned buildings. Many communities offer cooling centers in libraries and other public spaces. But those buildings may be closed or have limited capacity because of the COVID-19 pandemic, so also consider these options:

  • Do you have friends or family members living in an air-conditioned building who would allow you to shelter with them?
  • Do you know someone who would allow you to borrow a window AC unit?
  • Is your local government offering window AC units or temporary shelter in spaces where self-isolation is possible, such as in hotel rooms?
Know who is most at risk for heat-related illnesses
 Anyone may fall ill because of overheating, but some people are at special risk:
  • Athletes
  • Outdoor workers
  • People who lack access to air conditioning
  • Children
  • People aged 65 or older
  • People who take certain drugs. According to the Mayo Clinic, some drugs may reduce your body’s ability to maintain its temperature or hydration levels. Such drugs include beta-blockers, diuretics, antihistamines, tranquilizers, antipsychotics, and others.
Understand that global warming is making heat waves more frequent
 Carbon pollution from vehicles, factories, and power plants is trapping extra heat in the Earth’s atmosphere, much like an overly thick blanket can trap too much heat around you at night. That extra heat is making heat waves more frequent.

Please stay safe. Remember to CALL 911 if you or an elderly friend or family member is experiencing symptoms of heat-related illness.

There are several things you can do on your HVAC unit that will help you determine its efficiency. You will need to check and determine the following aspects that could play a part in how well it is performing: Below are four ways to improve your HVAC systems efficiency:

1 . You Keep Paying to Repair an Old System

Buying a new heating and air conditioning system is a significant investment. If your HVAC system must be fixed frequently, you could just be throwing money away on repairs.  You might be trying to hang on to your old unit to avoid the cost of buying a new one. Of course, occasional repair issues happen with HVAC systems.

Investing in a new unit can avoid repair issues and save money over time. With a new, energy-efficient unit, you may be able to save on your heating and cooling bills in the long run.

If you’re unsure whether your unit needs to be replaced, consider having it looked at by AC Dave Heating & Air. Then, you can get professional advice about whether it’s time for a replacement. You can also get advice about the best unit to purchase for your home.

  1. You Don’t Have a Programmable Thermostat

Investing in a programmable thermostat is an excellent idea for many families. With a programmable thermostat, you can avoid heating and cooling your home all day when no one is home.  You can also avoid walking into a hot or cold house after a long day. Your programmable thermostat can be programmed to suit your lifestyle and preferences. Investing in a programmable thermostat is an excellent idea for many families.

  1. You’re Using Other Sources of Heat or Air Conditioning

Some people are under the impression that using space heaters in the winter can be a more affordable way to heat the home. Even though a space heater may be able to save you money if you’re only heating a small room, it’s generally not as efficient as using your heating unit.

In addition, an HVAC system that’s working properly can keep your home at a more comfortable temperature than a space heater can.

The same principle is true with window unit air conditioners during the hot and humid summers. If you don’t use your system for cooling, you could still feel hot and sticky and might also end up with a higher electric bill.

  1. You Haven’t Had Your Unit Serviced

When you’re busy with other things, it’s easy to put off things like having your HVAC unit serviced. This big mistake can cost you money in a few ways. For example, when a professional services your HVAC unit, they will help ensure that your unit is operating as efficiently as possible. This can help you save on heating and cooling bills.

Additionally, failing to service your HVAC unit can lead to excessive wear and tear.  If your HVAC unit has not been serviced, it could be more prone to breakdowns.  If it hasn’t been adequately maintained, it might have to be replaced sooner. It’s a good idea to have your unit serviced seasonally to save money and ensure that your family stays comfortable.

If you’ve noticed any of these signs, then it might be time to implement one or more of the four ways to improve your HVAC systems efficiency. For help, contact us today at AC Dave Heating & Air (661) 270-1961.   Our Nate-trained experts will advise you on repairing or replacing your system. We’ll provide a solution to your heating and cooling problems that is best for your family.


Is A Ductless split right for you and your home? 

Is A Ductless split right for you and your home? 

Is a ductless heating and cooling system right for you and your ductless mini-split system vs a standard heating and cooling system?

Depending on the application, a ductless heating and cooling system could be a great addition to your home and improve its overall value.

Pros of a Ductless Heating & Cooling System

  1. Very Energy Efficient

Ductless heating and cooling systems are extremely energy efficient compared to a standard HVAC system.

Energy usage for these units is measured using a SEER rating (Seasonal Energy Efficiency Ratio).

Many of these units have a variable speed motor that can be adjusted based on need.

Also, the ductless system has an advanced inverter-driven compressor that operates in a cruise control style setting. It ramps up only when needed and then slows back down to conserve energy.

With a ductless heating and cooling system, you are generally looking at a 40% increase in energy efficiency compared to a standard ac unit! Options include more than 30 energy-star certified systems making it right for your home.

  1. Flexibility in Usage

One great benefit of a ductless system is its ability to “spot treat” certain areas of your home that are hard to heat and cool with your normal HVAC system.

If a room is located far away from your central HVAC system, the room may become hot in the summer and cold in the winter due to reduced airflow to that area of the home.

Without the hassle of ductwork needing to be run or air returns installed, these systems can be installed in almost any room you can imagine with room-by-room temperature control now at your fingertips.

Popular areas in a home for a ductless unit include:

  • Finished basements
  • Attics
  • Rooms located over garages
  • Sunrooms

Options for ductless systems include single rooms, multiple rooms, or even your entire home. Adding a ductless system is also a great way to increase your home’s value and right for your home.

  1. Better Air Quality

Unless you have a HEPA filter or an advanced air cleaning system installed on your central heating and cooling system, the air from your ductless unit will generally be cleaner.

A large factor contributing to this is the absence of ductwork.

Over time, ducts become lined with dust and other debris that slip past your furnace filter.

No matter how many times you change your furnace filter, if your air ducts are dirty, the air you breathe will be dirty as well.

By not having to worry about dirty ductwork, a ductless system can provide cleaner air consistently.

The ductless system also uses a sophisticated multi-part filtration system to reduce contaminants such as allergens, viruses, and bacteria from the air.

With regular cleaning of your ductless system, the filters can last up to 10 years!

  1. Quieter Operation

Compared to a standard central air system, a ductless heating and cooling system is generally much quieter during operation. Unless you are standing right next to the unit, you generally won’t even hear it operating.

As the ductless unit needs to only cool and heat one room, it does not have a loud blower motor that needs to force large amounts of air into your home.

During operation, you can generally expect noise to not exceed 19 DB in the indoor unit. Compare this to the average dB level of 40 at your local library.

  1. Can Both Heat and Cool

One of the greatest benefits of a ductless system vs a standard air conditioner is its ability to both heat and cool making it a year-round system and right for your home.

Tips for Summer Ready HVAC

Summer HVAC Tips from AC Dave Heating & Air
AC Dave Heating & Air 16 years in business


Now that summer is heating up, you’ll want to begin your seasonal preparations for your HVAC if you haven’t already. Specifically, you’ll want to get your air conditioner – whether it’s a central, portable, or window A/C unit – ready with our useful tips for summer ready HVAC.

The following tips will not only keep you from overheating this summer, but they’ll also keep your bank account from overheating from high energy bills.

It’s important to make sure that your air conditioner will be up to the task when you need to crank it up to full blast on those sweltering summer days. Schedule an annual tune-up for your air conditioner and have a professional perform preventative maintenance, check the refrigerant levels, and take care of any mechanical problems your unit might have. Even if your air conditioner seems to be in perfect working order, it might have small problems that can lead to large utility bills, not to mention even larger repair bills should those small problems turn into big ones.

Replace the air filter

At the start of the cooling season, check the air filter in the furnace and replace it if it’s dirty. Then check it every month that you run the air conditioner (and the furnace, for that matter) and if it is dirty replace it with a new filter. A dirty air filter blocks airflow, making your HVAC system work harder.

Clean the condenser coils

Cleaning the condenser coils makes it easier for the air conditioner to remove heat from the air, which also helps the condenser use less energy. Ideally, taking care of this job before the air-conditioning season starts.

First, turn off the AC inside the thermostat. Then shut off the condenser—look for a metal box attached to the outside of the house near the AC’s condenser unit and switch it to the off position. Some models have a block to remove instead of a switch. Then remove dried leaves, overgrown vegetation, and other clutter on and near the condenser unit.

Next, use a garden hose without a spray attachment to gently rinse the condenser coils with water. Avoid the electrical connections on the back. Flush the space between the coils too. Keep the water pressure low, or you could bend the fins. Turn the condenser on. Allow ample time for the coils to dry before turning on the AC inside the thermostat completely.

Check the insulation on the freon line

A freon line connects the evaporator on the air handler to the condenser outside. If the foam insulation that covers the line is torn, contact AC Dave Heating & Air to replace the insulation. 

Shut off the furnace humidifier

If your furnace is equipped with a humidifier, turn off the humidifier. Your air conditioner helps keep you cool by removing humidity from your house—so you don’t want the humidifier attached to your furnace to be pumping moisture into the air If your humidifier doesn’t have an on/off switch, move the damper door lever to the Cool position, which reroutes the cool air, so it doesn’t go through it.

You don’t want the first time you use the unit to be when it’s already sweltering hot outside. While the weather is still somewhat cool, do a few test runs with your unit. That way, you’ll be able to diagnose any issues before you really need the extra cooling power.

If you’re not comfortable doing any of the above steps or something not working, right? Need help getting your AC ready for warm weather? Keep your cool and let our experts handle it, call AC Dave Heating & Air at 661-270-1961 to schedule your appointment today.

Thermostat doesn’t turn on / thermostat screen is blank

This two-week informational topic will discuss the most common 8 reasons why your thermostat is not working, whether that be that it’s not turning on or that the screen is blank.


Incorrect thermostat setting: If the thermostat has been turned off, its display will be blank. Thermostats should be left on throughout the year rather than being turned off, but accidental adjustments are possible. Verify this setting and ensure the thermostat itself is on.

Dead Batteries: Check your batteries often to ensure this is not the issue. Without batteries, the thermostat cannot turn on or control the heating unit.

No electrical Power: Some thermostats are hardwired and powered by the home’s electrical system. A tripped breaker or blown fuse in the electrical panel may prevent the thermostat from receiving power. Resetting the power or replacing the blown fuse will correct this issue.

Loose Wiring: If thermostat wiring becomes loose, its operation may be disrupted. An HVAC technician here at AC Daves Heating and Air is able to identify issues with wiring and electrical connections within the thermostat/ Sometimes these issues are repairable, while other times it may be necessary to replace the thermostat.

Please make sure you always put your HVAC system in the hands of a licensed Technician. Call us if you need assistance. TEL: 661 270 1961.  LIC # 877683




Furnace Filter become clogged faster than Usual… Part3

High levels of indoor contaminants:

High levels of indoor air pollutants create a bigger burden for furnace filters and they become clogged much faster. Filters typically don’t last as long in homes with indoor pets or where indoor smoking takes place. Weatherizing the home to prevent winter heat loss traps contaminants indoors which can increase this issue.

If you haven’t changed your winter filters out yet, you may want to start thinking about it soon. If you are unsure what filters you need, or you would prefer a professional Licensed HVAC company to come out and do a service call, please call us here at AC Dave Heating & Air. We are here to serve.
