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
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.
If you know that your HVAC system, may not be in the best condition, you may consider investing your Tax Refund into replacing or upgrading your HVAC system!
Higher efficiency units may cost a little more, but can result in more rebates, incentives. Government agencies and power companies want to encourage the use of higher efficiency equipment to help reduce power consumption. Incentive, by way of direct rebates, tax credits or tax reductions (depending on your geographic location) may be offered as a reward.
TIP: Incentives are usually tied to efficiency ratings and performance. The efficiency of AC units is measured by “Seasonal Energy Efficiency Rating” or “SEER”, while heat pumps are measured by “Heating Seasonal Performance Factor” or “HSPF’ or “HERS”. A higher “SEER” or “HSPF / HERS” rating, signifies higher efficiency.
As April falls into May, the housing market also starts to pick up. So another good reason to update, or at least get your system checked over, is because, it’s one less thing to worry about if selling your home. Alternatively, if purchasing, make sure the HVAC system of your new home is inspected by a LICENSED HVAC Specialist.
Regularly scheduled maintenance by a LICENSED service contractor is a MUST to keep your system in proper working order. Many of the most common Heating & cooling system repairs can be avoided with proper maintenance by a certified service contractor. You have likely invested thousands of dollars in your home heating and cooling system, so why not protect that investment? If you neglect to perform regular maintenance you will most likely experience unexpected and costly breakdowns, increased energy costs, poor performance, and frustration. Let’s face it; Living in California can be uncomfortable in the Winter and Summer months, so why wouldn’t you want your heat and cooling source to be in tip top condition?
Protect your investment, and gain peace of mind. Call AC Dave Heating & Air to have one of our Licensed HVAC service team inspect your system today!

How to fix it: An air conditioner that is running but isn’t cooling is one of the most common problems. Unfortunately, it has a number of potential causes. It could be a dirty air filter, low refrigerant level, or a blocked condensate drain. You can also check for ice around the coils or a dirty outdoor compressor. Or, you may need to add more coolant to your system. Another problem: it may simply be too hot outside to cool your home to your liking. Most air conditioners can only cool to about 20 degrees lower than outside air temperatures.
The problem: Your air conditioner isn’t coming on at all.
How to fix it: An air conditioner that simply won’t come on may indicate a problem with the thermostat. Set your thermostat to cool and bump down the temperature setting, then check your electrical panel for a tripped breaker or blown fuse. Check for issues in the power supply by looking at wires. You can also check your furnace power switch and thermostat for any problems.

An air conditioner that isn’t working properly is a major problem, particularly in the hot summer months. It can cripple your home, and if it’s hot enough, even require you to spend the night elsewhere. It’s important to properly maintain your air conditioning system with cleaning, air filter changing, inspections, and other essential maintenance, but even the best-maintained units will sometimes go awry. Read on to find out what the most common air conditioner problems are — and how you can fix them.
The problem: Air isn’t coming out of the registers.
How to fix it: If no air is coming out, the fan on the outside unit may not be running. Believe it or not, this is an easy problem you want to have, as it typically means that the breaker is simply tripped and needs to be reset. Or you may have another easy problem: the blower belt, which will simply need to be replaced. Other causes include a problem with your thermostat, control board, or wiring. Your condensate pump reservoir may be full as well.

The furnace filter becomes clogged faster than usual
Air filters need to be replaced on a regular basis, as filters become clogged with contaminants pulled from circulating air. It is normal for filters to require more frequent replacement during the winter months due to increased heating system operation – however, abnormal issues may cause your filter to become clogged sooner, requiring replacement much earlier than expected. It is recommended to replace your filter a minimum of twice a year.
The blower fan is set to ON. When the fan is set to ON at the thermostat, the blower runs continuously. As air constantly circulates through the HVAC system, it completes more passes through the filter, and the filter fills with contaminants at a faster rate. Turning the fan to AUTO is a furnace troubleshooting step that can help filters last longer.
Duct leaks. Duct leaks allow more contaminants into the indoor air supply from the unconditioned areas surrounding the ductwork. With more contaminants in the air, the filter will fill faster as air circulates.
Dirt accumulation near return air vents. The home’s return air vents feed indoor air back to the heating system for conditioning. Accumulation of dirt on or around the return air vent introduces more contaminants to the air supply and forces the filter to fill at a faster rate in order to keep them out of the heating system.
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 concentrations of indoor air contaminants.

The heating system shuts off shortly after coming on. Feb 28, 2022
Heating equipment typically cycles for 10 to 15 minutes at a time. When the system starts up and shuts down again within a minute or two, this issue is known as short cycling. Short cycling has many causes – despite its cause, this issue causes damage to the HVAC equipment along with discomfort in the home, leading to higher heating bills and more frequent system repair needs.
1. Thermostat malfunction.
Faulty electrical connections, dirty temperature sensors, improper location of the device, or even an unlevel older mercury model are all issues that cause short cycling stemming from the thermostat. Gentle cleaning of sensors, recalibration, repositioning, or replacement may be used to solve these issues.
2. Improper thermostat anticipator calibration.
Some older manual thermostats have adjustable heat anticipators which warm up the interior of the thermostat in order to prematurely end a heating cycle. This is done in anticipation of residual heat in the ducts, allowing it to reach the living areas while avoiding overheating the space. Improper calibration of the anticipator can end heat cycles too early, causing short cycling. They can be adjusted, or the entire thermostat can be upgraded.
3. Overheating can be caused by poor airflow.
Dirty air filters and closed room vents restrict airflow through the furnace, which causes interior components to overheat. The furnace’s limit switch shuts down operation when internal temperatures are too high for safe operation. Replace the furnace filter and check all room vents to ensure they are fully open. A blocked flue pipe can also cause furnace overheating – blockages must be found and cleared not only to prevent short-cycling but possible carbon monoxide exposure in the home.
4. Faulty Flame Sensor In Furnace.
The flame sensor detects the presence of a flame when the furnace’s gas valve is open, working to prevent dangerous gas leaks and explosions. When it becomes dirty from soot, it may not detect the flame and the system shuts down shortly after starting as a safety measure. The existing sensor can be cleaned or replaced if broken, as corrosion is a common cause of damage to the component.
5. Faulty furnace draft inducer motor.
Many newer furnaces feature a draft inducer motor that exhausts combustion gases leftover from the prior heating cycle. If its air pressure switch does not detect proper airflow through the heat exchanger, it shuts the furnace down as a safety measure. This malfunction may be caused by an obstructed flue pipe or a fault in the pressure switch or the motor itself.
6. Oversized heating equipment.
When a heating system is installed that is too big for the home, it produces larger amounts of heat fast – this is not a good thing. Air heats up quickly, and the thermostat shuts down the heating cycle once the set temperature is detected. Repetitive short cycles wear out components, leading to higher energy consumption and more equipment breakdowns. Replacement is the only solution.
When the thermostat is properly powered and correctly set, the furnace should activate once the set temperature is reached. The thermostat triggers the furnace’s ignition system, which ignites the burners to start the heating process. If the furnace doesn’t ignite, the home receives no heat.
The pilot light is out.
Furnaces over 10 years old are often equipped with standing pilot ignition systems that utilize a constant burning pilot light. If the pilot light goes out, heating fuel is not ignited. The furnace’s owner’s manual typically includes instructions for relighting the pilot light. However, if the pilot continues to go out, check for nearby drafts. If no drafts are to blame for extinguishing the pilot, the cause may be a faulty thermocouple, which may be corrected through cleaning of the component or replacement. A bad gas regulator could be causing fuel supply issues with multiple gas appliances in the home. Contact your utility providers for immediate assistance.
Electronic ignition is dirty.
Accumulation of carbon on electric ignitors can prevent proper ignition of the furnace. A repetitive clicking noise usually occurs, which indicates the ignitor is not working correctly. Careful cleaning is needed to remove carbon. This is a fragile component, so if you feel uncomfortable doing this, please call our office at 661 270 1961.
Cracked hot surface ignitor element.
If the hot surface ignitor’s heating element has cracked, the furnace will not ignite. Typically, this component has a service life of three to five years and requires periodic replacement, though it may fail sooner when exposed to improper handling or short cycling. Careful homeowners may be able to replace this component, or you can call AC Dave Heating & Air and we can get the job done.
Ignitors sustain damage due to wear and tear, occasionally requiring replacement. To diagnose a damaged ignitor, a multimeter is used. Depending on the type of ignitor and ignition system, replacement may be a complex task and should be left to a licensed HVAC professional.
The wrong ignitor was installed.
Improper furnace installation can lead to the wrong type of ignitor being put into use. An ignitor that requires incorrect voltage can cause the ignition system to fail. Furnace troubleshooting includes replacing the component with the proper part for the furnace’s ignition.
Malfunctioning limit switch.
When operating normally, the limit switch shuts off the ignitor when the furnace reaches high temperatures. If the limit switch malfunctions, it may unnecessarily impede ignition. Poor airflow and dirty filters may also cause the ignition to be shut down prematurely by the limit switch (Replacing filters can prevent this issue and correct overheating). If the limit switch is damaged, it needs to be replaced.
