Southern California homeowners know that Santa Ana winds bring more than dry air and high gusts – they often arrive hand-in-hand with wildfire smoke.

The combination creates difficult conditions for both your home and your HVAC system. If your air conditioner or heater is not prepared, you may end up with poor indoor air quality, clogged filters, and systems that have to work harder than usual.

The good news is that with the right steps, you can protect your HVAC system and your family’s comfort. Below, we’ll cover what Santa Ana winds and wildfire smoke mean for your home, common issues that come up, and how to prepare your system effectively.

Why Santa Ana Winds and Wildfire Smoke Affect HVAC Systems

Santa Ana winds are hot, dry winds that sweep through Southern California, often reaching speeds strong enough to carry dust, pollen, and smoke deep into neighborhoods. When combined with wildfire smoke, these winds push harmful particles into the air you breathe.

Your HVAC system is designed to circulate and filter air, which means it becomes the first line of defense against airborne irritants. However, the influx of dust and smoke can overwhelm filters, infiltrate ductwork, and reduce your system’s efficiency. Without preparation, your home’s air quality can decline quickly.

Signs Your System is Struggling

It’s not always easy to tell when outdoor conditions are impacting your HVAC system, but there are several warning signs to watch for:

• Dust buildup around vents even after cleaning
• Air that smells smoky or musty indoors
• A system that runs longer than usual to maintain temperature
• More frequent allergy or asthma symptoms in your household
• Unusually high energy bills during windy, smoky periods

Recognizing these signs early allows you to take action before more serious problems develop.

Steps to Protect Your System and Air Quality

Step 1: Start with a Fresh Air Filter

Your air filter is your HVAC system’s first defense against airborne particles. During Santa Ana season, filters clog much faster due to the extra dust and smoke in the air. Replacing your filter before winds pick up helps your system start clean and maintain airflow.

Look for high-efficiency filters with a MERV rating of at least 8-13. These can capture finer particles, including smoke, while still allowing good airflow. Keep spare filters on hand so you can replace them more often when conditions are severe.

Step 2: Seal Air Leaks Around Your Home

Dust and smoke can sneak in through small gaps around windows, doors, and even ductwork. Sealing these areas helps your HVAC system work less to maintain indoor comfort and keeps harmful particles out of your home. Caulking, weatherstripping, and duct inspections all make a difference when preparing for Santa Ana winds.

Step 3: Switch to Recirculation Mode

Most HVAC systems and thermostats allow you to switch between bringing in outdoor air and recirculating indoor air. During wildfire smoke events, always choose recirculation mode. This prevents smoky air from being pulled into your home and allows your filter to focus on cleaning the air already inside.

Step 4: Schedule a Professional HVAC Checkup

Preventive maintenance is critical during wildfire season. A professional technician can clean coils, check ductwork for leaks, and ensure your system is working efficiently. This not only improves your indoor air quality but also reduces the risk of breakdowns when you need your system most.

You can learn more about professional HVAC maintenance services and why they matter year-round.

Step 5: Consider Upgrading Indoor Air Quality Equipment

If your family struggles with allergies or respiratory conditions, or if you want extra protection from smoke, there are several upgrades to consider:

• Whole-home air purifiers: Installed directly into your HVAC system, these remove a wide range of airborne pollutants.
• UV lights: These help neutralize airborne bacteria and viruses circulating in your ductwork.
• Dehumidifiers: Although Santa Ana winds bring dry air, balancing humidity indoors helps with comfort and filtration efficiency.

These add-ons work with your existing system to provide cleaner, healthier air during harsh conditions.

Step 6: Keep Outdoor Units Clear

Santa Ana winds carry debris like leaves, dirt, and trash, which can collect around your outdoor AC unit. Clear at least two feet around the unit to maintain proper airflow. After a wind event, inspect the unit for debris buildup and call a professional if you notice unusual noises or reduced performance.

Long-Term Protection

Preparing your HVAC system for Santa Ana winds and wildfire smoke is not a one-time effort. Making filter checks, system maintenance, and air quality upgrades part of your routine ensures your home is always ready for the next event.

Regular inspections, timely repairs, and proactive measures like sealing ductwork not only improve air quality but also extend the life of your system. For homeowners in Southern California, these steps provide both comfort and peace of mind.

Are your utility bills climbing as fast as the temperature? Staying cool during a Riverside summer can be expensive – but it doesn’t have to be. If you’re wondering how to save on energy bills during summer, you’re not alone.

At Dragonfly Heating & Cooling, we help Riverside homeowners keep their homes comfortable without overspending. In this guide, we’ll break down how to reduce cooling costs with smart strategies, simple home improvements, and HVAC upgrades that make a difference.

Why Summer Energy Bills Spike

As outdoor temperatures rise, your air conditioner runs longer and works harder to keep your home cool. But it’s not just the heat – factors like:

• Poor insulation
• Leaky ducts or windows
• Outdated equipment
• Indoor heat sources (like ovens or dryers)

… can cause your energy bills to rise quickly. Knowing how to address these issues is the first step in keeping cooling costs under control.

Smart Cooling Strategies To Lower Energy Costs

You don’t need to suffer through the heat in order to cut costs. Try these energy-saving strategies that really work:

Thermostat Settings That Save Money

Your thermostat is one of the most powerful tools for managing summer energy usage.

• Set your thermostat to 78°F or higher when you’re home
• Raise it by 7–10 degrees when you’re away for more than a few hours
• Use a smart thermostat to automate schedules and reduce waste

Each degree you raise your thermostat can cut cooling costs by about 3%–5%. Combine that with fans and good air circulation, and you’ll stay comfortable without overworking your system.

Easy At-Home Adjustments

Small changes around the house can lead to big savings:

• Seal air leaks around doors, windows, and ductwork with weather stripping and caulk
• Close blinds or curtains during the hottest part of the day to block out radiant heat
• Run ceiling fans counterclockwise to create a wind chill effect that helps you feel cooler at higher temperatures

These adjustments reduce how hard your AC has to work and improve the overall comfort of your home.

HVAC Maintenance and Upgrades That Pay Off

Your cooling system is the heart of your summer comfort, and the biggest opportunity for energy savings.

Regular AC Maintenance

• Replace air filters monthly during high-use months
• Clear debris around your outdoor condenser
• Schedule seasonal tune-ups to catch issues before they become expensive problems

Energy-Efficient Upgrades

If your system is more than 10–15 years old, consider these upgrades:

• High-efficiency AC units – Use less energy while cooling more effectively
• Zoning systems – Cool only the areas you use, reducing waste
• Duct sealing – Prevents cool air loss in transit
• Smart thermostats – Learn your preferences and optimize your energy use

Many of these upgrades qualify for rebates or tax credits, which make them more affordable than you might think.

When to Call a Professionals

It’s time to call your HVAC technician if you notice:

• Unusually high energy bills
• Uneven cooling in different parts of the home
• Constantly running AC system
• Hot or humid air coming from vents

Catching and correcting inefficiencies early can save you money all season long. Routine service helps ensure your AC isn’t silently wasting energy behind the scenes.

Your heating and cooling system’s efficiency and lifespan directly affect your home comfort and energy costs. If you want reliability at every stage – whether it’s installation, repair, or replacement – you need an HVAC contractor who brings both precision and expertise.

In this guide, Dragonfly Heating & Cooling shared trusted tips to help you choose the right HVAC contractor. A smart choice today can save you money, prevent safety issues, and ensure your comfort for years to come.

1. Start With Local Recommendations

Word of mouth is still one of the most reliable ways to find a trustworthy contractor.

Ask friends, neighbors, and family members in your area about their experiences with HVAC companies. First-hand recommendations give you honest insight into quality, reliability, and customer service.

2. Verify Their Credentials & Certifications

Before letting anyone work on your HVAC system, make sure they’re properly qualified.

What to look for:

• State HVAC licenses
• Liability insurance coverage
• NATE-certified technicians

These credentials show the contractor is trained, experienced, and working to professional standards.

3. Look at Online Reviews

Reviews are helpful, but you need to go beyond star ratings. Focus on:

• Consistency in service quality
• Communication and responsiveness
• How the company handles issues or callbacks

Reliable contractors will have positive patterns across multiple platforms, not just one.

4. Request a Detailed Home Evaluation

A good contractor won’t offer a quote without seeing your home first. A proper evaluation includes:

• Checking your current HVAC system and maintenance history.
• Reviewing your home’s square footage and layout
• Inspecting ductwork and insulation
• Asking about your comfort needs and energy goals

If they skip this step, it’s a red flag.

5. Compare Multiple Written Estimates

Don’t settle for the first quote; you want to get a few, and be sure to pay attention to equipment quality, labor and material breakdowns, warranty terms, and long–term value. Remember, the cheapest option isn’t always the best.

6. Ask About Warranties & Service Guarantees

A confident HVAC contractor backs their work with solid warranties. Ask what’s covered, how long it lasts, and what happens if something goes wrong post–installation. This is a great way to gauge their long-term commitment to your satisfaction.

7. Evaluate Their Communication & Responsiveness

The best contractors are clear, respectful, and easy to reach. Did they explain things in a way that made sense? Were they patient with your questions? Strong communication now usually means strong service later.

8. Make Sure They Use Proper Sizing Methods

System sizing is one of the most critical parts of HVAC design, and one of the most commonly overlooked.

Avoid contractors who size systems based only on square footage. The right method includes heat load calculations that factor in insulation, windows, orientation, and other variables.

9. Check Their Business History & Reputation

Choose a company that’s established and well-regarded in your area. Contractors with a long-standing presence in Orange County have a reputation to maintain and are more likely to be around if you need support later on.

Your HVAC unit running non stop will undoubtedly leave you scratching your head because you know it’s not right. The unit running continuously puts a huge strain on the components, increases the risk of sudden breakdown – and shortens your equipment’s lifespan.

(Not to mention, it makes the system’s efficiency irrelevant.)

With every day that passes, you’ll lose a LOT of money – so, what can you do in this scenario? It depends on the cause of the problem. We’ll look at the various reasons your HVAC system runs without stopping and what you can do about each one.

Thermostat Problems

A malfunctioning thermostat is one of the most common reasons your HVAC system will run without stopping. It may be reading the temperatures wrong due to an internal malfunction, wrong programming or because of poor placement.

Check the thermostat to ensure you’ve entered the right settings. If necessary, reset the system and start over.

If that doesn’t fix the problem, consider moving the thermostat to a more central location where it’s not in direct contact with drafts, sunlight or other heat sources.

Dirty Air Filters

Clogged HVAC filters will cause the system to work harder to deliver hot or cool air.

Thankfully, this is an easy fix.

Replace the filter if it’s dirty and your system should go back to normal. Ideally, you should clean or replace your HVAC filters every month to ensure consistent airflow, efficient performance and healthy indoor air quality.

Refrigerant Leaks

Low refrigerant levels will leave your HVAC system running non-stop as it has to work harder to complete the heat transfer process.

Some confirmatory signs of refrigerant leaks include ice buildup on the refrigerant lines and hissing sounds while the system is in use. However, there’s no DIY fix here. You’ll have to call an HVAC technician to deal with the leak.

Electronic Control Board Issues

The electronic control board on an HVAC system controls all the processes that deliver your conditioned air. Certain issues in the circuitry can throw the configurations off balance, causing your system to run non-stop.

Control board issues are highly complex, and you have to call an HVAC technician who will test the board and recommend a replacement if necessary.

Poor Equipment Sizing

Have you noticed your HVAC system running non-stop almost from the first day of installation? There’s a high chance that you have a system that is too small for your space and is not powerful enough to reach your desired temperatures.

The only solution here is to call a professional HVAC technician to recommend and install an accurately sized unit for your home (hopefully, you’re still within your warranty window!).

Since Southern California has long, hot summers with wet and chilly winters, you’ll likely use your heating and cooling system often to remain comfortable indoors. Unfortunately, HVAC units are major energy consumers, so running your equipment too frequently without the proper care will decrease HVAC performance and increase energy expenses. 

The team at Dragonfly Heating & Cooling understands that several performance measures make understanding HVAC efficiency and performance capabilities easier. Here we discuss those key points and offer tips for improving heating and cooling system performance for Southern California properties. 

How to Assess an HVAC System’s Energy Efficiency

A significant portion of a furnace, air conditioner, or heat pump’s performance level ties into how well it uses energy. Choosing the right energy-efficient equipment is the first step in optimizing system performance.

Different ratings or performance measures help explain whether a system’s design makes it energy-efficient. Though several scientific ratings are available, the top ones are:

• Seasonal Energy Efficiency Ratio (SEER): Air conditioners with SEER ratings above 16 can lead to substantial energy savings. 
• Heating Seasonal Performance Factor (HSPF): This rating measures heat output in heat pumps in British Thermal Units. The ideal rating range is between eight and ten.
• Energy Efficiency Ratio (EER): An EER rating measures the cooling capacity of a heat pump or air conditioner. The higher the rating, the more energy-efficient the system is. 

Whenever your home or business needs a new HVAC system, refer to its ratings to determine if the model has the energy efficiency baseline you need for your property and energy usage needs. For instance, getting an air conditioner with a SEER rating over 13 is best if you want an energy-efficient HVAC unit. 

Top 4 Ways to Optimize HVAC Performance

To improve HVAC performance, consider the following tips and strategies:

• Change Air Filters: Every HVAC system has an air filter that traps dirt, dust, and other airborne debris as air passes through it. You must change or clean the filter at least once every season to prevent clogs from restricting airflow and reducing HVAC performance.
• Use Your Thermostat Smartly: Anytime you leave your property for more than four hours, you should adjust your thermostat up or down a few degrees, depending on the season. Letting your equipment run when no one is present is a waste of energy. 
• Clean Your Compressor: The compressor unit is the outdoor portion of an HVAC system that disperses heat waste from buildings. Always maintain a clear space around it by removing weeds, plants, and debris from it. This step is necessary to prevent airflow restriction.
• Schedule Annual HVAC Inspections: Getting a professional HVAC inspection each year is important for maintaining great system performance. The technician will assess and clean your equipment and calibrate everything for optimal efficiency.

Getting an HVAC tune-up is a crucial maintenance step for keeping your air conditioning and heating systems operating proficiently year-round. One does not approach the process only when a problem arises; a tune-up can help prevent expensive breakdowns in the first place. It can also save you money by keeping everything running at peak efficiency. While each system is different, there are things that any HVAC tune-up checklist should include.

START WITH CARBON MONOXIDE TESTING

Safety should be the top priority, so a tune-up checklist needs to include combustion testing of your furnace. A fuel-fired furnace does not spend all its gas during operation and releases some of that fuel as carbon monoxide (CO). Inspecting the level of CO released while the furnace is running can tell you if it is wasting too much gas.

Trained personnel can inspect the furnace with equipment once temperatures in the system stabilize and at each heat exchanger cell. That will help keep your furnace running efficiently and prevent unwanted CO buildup that could endanger everyone in the home.

TEST ALL HVAC SAFETY EQUIPMENT

Inspecting your HVAC’s safety equipment to verify it is working is another crucial step on every tune-up checklist. This equipment includes gas shut-off valves and the limit switch that keeps temperatures from climbing too high around the combustion chamber. The air pressure switch, carbon monoxide detectors, and mercury flame sensors or thermocouples that help with pilot light safety will be checked as well.

Our technicians will check safety equipment to make sure it operates as intended. They will identify potential issues and help to correct them. This safety equipment protects your family, home, and HVAC system from wear and potential hazards.

CHECK BURNERS AND CLEAN THEM IF NEEDED

The burner plays an integral part in your heating system by mixing air and natural gas to produce the flame that heats your home. Dirt and other debris can cause burners to operate poorly, and connection or valve issues could develop over time.

Technicians check the flame to verify it is burning blue and evenly across the burner, cleaning it if needed. Connections might work loose and require reattachment or replacement. Properly functioning burners are cost-effective, produce adequate heat, and produce minimal carbon monoxide, no matter if the furnace is running or off.

CHANGING AND CLEANING FILTER MEDIA

A clean filter can stop dust, pet dander, pollen, and other small particles from circulating throughout the air column in your home. Those particles become trapped in the filter media and clog it over time. A dirty filter is less efficient at keeping the air clean and can restrict airflow through your HVAC system.

No tune-up checklist would be complete without checking, cleaning, or replacing the filters. Disposable filters need to be changed every three months. Permanent filter systems can be cleaned and reused. Our technicians will inspect your filters to help keep the air you breathe clean.

EXAMINING THE DUCTWORK

Your system’s ductwork moves air from your air conditioner, furnace, and ventilation pipes throughout your home. This integral part of your HVAC system can become filled with debris or become damaged. That leads to reduced air circulation and poor air quality.

A tune-up checklist should include examining the airflow through your HVAC’s ductwork. A technician can look for signs of dirty air flowing out of a
vent, limited airflow, rooms with different temperatures, or signs of vent damage near seams. You may need to have the ducts cleaned, patched, or resealed along seams to fix the problem.

VERIFYING THE THERMOSTAT IS WORKING PROPERLY

Your HVAC thermostat is the brain, sensing the air temperature and turning your air conditioner or furnace on and off when needed. A tune-up list should include inspecting the thermostat to verify it is sensing the proper air temperature and that all connections are secure.

Trained professionals can examine your HVAC system to verify the thermostat is kicking on your air conditioner or furnace when adjusted to various temperature ranges. That includes short cycling when your HVAC shuts down before full cooling/heating cycles are complete. A tune-up can also help you set programable thermostats to match your schedule and needs.

CHECKING THE SYSTEMS CONTACTORS AND RELAYS

Your HVAC contactors and relays open and close circuits, controlling electrical flow to your system’s components. That flow is what turns equipment on and off. Signs these components are not working include inconsistent operation, noises like chattering or humming sounds, and signs of charring or melting.

Our technicians can inspect these components using specialized equipment like multimeters. They can isolate and test these parts, replacing them if they do not close or open correctly. This tune-up step will allow your HVAC system to produce consistent temperatures in your home and help equipment shut down or start up properly.

CLEAN AND FLUSH DRAIN LINE AND TRAP

The HVAC system requires a condensate drain and trap to prevent the air from the system from escaping. It prevents conditioned air from blowing outside in a positive pressure system. When attached to a negative pressure system, it stops condensation from pooling in the air handler.

Our personnel can inspect the air conditioner drain tube to check that it is not blocked and unclog it if needed. That can prevent overflow at the condensate plate and stop algae growth and other debris from creating a block. They can also verify water is flowing correctly at the trap.

CHECKING THE AIR CONDITIONER REFRIGERANT LEVELS

Your HVAC system needs to maintain a proper level of the chemical compound used to absorb heat and provide cool air after running through compressors and evaporators. Low levels of this refrigerant make your air conditioner lose its ability to transfer heat, resulting in warm air circulating within your home. Our trained technicians can inspect and handle these chemicals in a safe and environmentally friendly manner, keeping your HVAC running cool.

ADJUST BELTS AND LUBRICATE MOVING PARTS

HVAC belts connect components like the motor pulley to the blower wheel pulley, helping push air throughout the ductwork. Adjusting these to the proper tension should be standard during a tune-up to prevent slippage and belt deterioration. Motor bearings and other moving parts require lubrication to reduce friction and reduce wear and tear on these parts. Regular lubrication can also reduce the amount of corrosion and heat buildup that affects sensitive components.
