While there are some important spring HVAC maintenance tasks you can take on yourself, many others can only be safely performed by a professional. Call AC Dave heating & Air to schedule your Spring check.
Airflow within your home:
Replace the filter. If you do not know where your system’s air filter is, or how to replace it, ask your HVAC pro to show you.
(Here at AC Dave Heating & Air, we replace your filters as part of our maintenance agreement.) Then, change your filters regularly. How often depends on your system and the type of filters your use. When in doubt, change them out every 6 months.
NOTE: A dirty filter can reduce efficiency, increase operating costs and damage your system.

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.
WEEK ONE:
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… Part 3
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.
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.
